Soup, Nuts and Weight Loss

It is clear that how much food we eat impacts our health and body weight.  Research is also making it clear that certain foods, particularly high-energy, low-nutrient foods, can have a negative effect on our health and cause weight gain.  In contrast, other types of foods can have a beneficial effect on our body weight and overall health.  Two recent studies explored the impact of soup and nuts on body weight changes.

In the first study, researchers investigated the relationship between soup consumption and body weight and other health factors in 103 Japanese men.  The men's intake of soup was measured using a validated food-frequency questionnaire and the link between soup consumption and body weight was analyzed.  The study investigators reported that average soup consumption in this group of Japanese men was 7 times per week and that a higher frequency of soup consumption was linked to a lower body mass index (BMI), smaller waist size, and smaller waist-to-hip ratio.  This study suggests that increased frequency of soup consumption decreases obesity risk factors.

In the second study, researchers analyzed several long-term population-based studies on the impact of nut consumption on body weight changes.  According to the researchers, two large studies reported that adding nuts to one's regular diet reduced long-term weight gain.  A study of over 1,200 people consuming a Mediterranean diet showed that addition of tree nuts to the Mediterranean diet for 1 year had a beneficial effect on waist size.  A third study of nearly 12,000 subjects showed that eating greater amounts of nuts helped reduce yearly weight gain with individuals consuming more than 4 servings of nuts per week gaining an average of 1/2 pound per year compared to about 3/4 pounds per year in those eating fewer than 4 servings of nuts per week.

These are rather interesting studies that might help many of us make healthier food choices.  Nuts are a tasty treat for most people that don't have nut allergies; however, most nuts are rich in protein, fat, and calories.  Their level of fat and calories has made nuts a somewhat cautionary food item for individuals trying to lose weight.  Fortunately, the fat in nuts is mostly of the healthier, unsaturated variety.  According to the study above, nuts might actually have a beneficial effect on weight gain prevention.  However, nuts are one of those snacks that we typically find very easy to over eat, so we should still practice moderation. 

Soups can make a very healthy meal.  If you make your own, make sure to add plenty of vegetables.  This will make the soup a very nutritious meal that will help you get your recommended daily amount of vegetables as well as increase your dietary fiber consumption.  Just remember to go easy on the salt.  This is also true for canned soups, which often contain very high levels of sodium.  Adding soup to your weekly menu plans can be a delicious and satisfying choice, just be sure to choose healthy options.

Weight Loss Misconceptions Still Persist

McNeil Nutritionals, LLC, a marketer of nutritional products, recently revealed some of the results of a recent survey they conducted regarding what American women believe about weight loss and healthy eating.  While the full survey does not appear to be available, a press release discusses some of the results.  Some of the results of this survey are outlined below.

Body Image Perceptions:

• More than 33% of American women think about their body weight at least 3 times each day.
• 81% of the women surveyed do not believe that they are at their ideal body weight.
• Nearly half feel that they will reach their ideal body weight this year.
• However, many American women believe that drastic, overly-strict lifestyle changes are needed to reach and maintain their ideal body weight.

 Dieting:

• 91% of the American women surveyed did not realize that they had to burn 3,500 calories to lose 1 pound of body weight.
• 35% of women surveyed believed that they would need to cut something like sweets or snacks out of their diet completely.
• 39% were under the impression that they would need to reduce their food consumption to below 1,000 calories per day.
• Difficulty in losing weight was frequently attributed to family obligations, finances, stress, and other demands on time.

Healthy Eating:

• Only 17% of the women surveyed ranked the nutritional value of foods as the most important factor when making a purchase decision.
• Price, taste, and quality of foods purchased were more important than the foods' nutritional value in most cases.
• 70% of women added sugars to their foods and beverages.

Among these results were some interesting observations.  If these results are representative of the population in general, it would suggest that the vast majority of us do not give the nutritional value of our foods enough consideration.  Additionally, we appear to hold the opinion that weight loss through dieting has to be a grueling, unpleasant endeavor that might require a severe restriction in the amounts and types of foods we eat.  Overall, it appears that the health professional community still needs to work on getting the appropriate messages out about healthy ways to lose weight.  For example, while restricting the amount of calories we consume is an important part of losing weight, the amount shouldn't be so much that it drops you below 1,000 daily calories.  Also, losing weight does not have entail dramatic lifestyle changes.  In fact, making a number of small changes in our eating habits can go a long way towards reaching one's weight loss goals.  A good example from the results of this survey would be to simply decrease the amount of sugars one adds to their foods and drinks or start reading nutrition labels.  Both these simple changes could improve a person's eating habits dramatically.  Reading blogs like this one and others is a great way to become more informed about healthy weight loss and good nutrition.

Enhance Satiety With Soluble Fiber

Fiber is an important part of our daily diet and can be obtained easily from fruits and vegetables.  It is currently recommended that we consume about 25 - 35 grams of fiber each day in order to obtain the many benefits of fiber.  Unfortunately, it has been reported that less than half of us consume enough fiber.  One way to increase our fiber intake is to add it to the beverages we drink.  Many fiber supplements easily dissolve in liquids, making this a simple way to increase our fiber intake.  A recent study on the impact of soluble fiber and appetite suggests that another benefit of soluble fiber might be its ability to make us feel fuller.

In this nutrition research study, study investigators examined the impact of four types of fiber on feelings of fullness (satiety) and energy intake at the next meal.  For this study, 14 men and 22 women were enrolled and completed 6 study sessions.  Study volunteers were asked to consume a solid snack with a liquid beverage in the mornings.  This liquid beverage contained one of four different types of fiber: soluble fiber dextrin, soluble corn fiber, polydextrose, and resistant starch.  The volunteers' feelings of fullness were measured every 20 minutes for 3 hours and 40 minutes after consumption of this snack and beverage.  Study volunteers were then provided a noontime meal and the amount of food not eaten was measured.  The study investigators reported that all four fibers and the control snack with a similar amount of calories increased feelings of fullness and less hunger compared to a snack with lower calorie levels.  However, the researchers indicated that only the consumption of the soluble fiber dextrin resulted in a reduced calorie intake at the noontime meal.

This is an interesting study that suggests not all fibers are the same when it comes to their impact on our overall food consumption.  While all four of the fibers tested helped the study subjects to feel full and reduced their hunger, only consumption of the dextrin fiber altered how much food the study subjects consumed.  While many people use fiber supplements solely for the health benefits of fiber, some use fiber as a weight loss tool because of fiber's ability to reduce our hunger.  While reducing hunger with fiber consumption can be a good weight loss tool, this study suggests that picking the right fiber might be necessary to obtain the full weight loss benefits of fiber.  Since this was a small study of only a few adults, it will be necessary to confirm these results in a larger study.  In the meantime, if you are considering adding fiber to your drinks in an attempt to lose weight, you might want to consider trying different forms of fiber to find what works best for you.

Plant Proteins Support A Healthy Body Weight

Previous research has suggested that meat consumption is linked to weight gain, though this remains a topic of fairly intense debate.  While meat is a good source of protein, many meats, particularly red meats, are also a high source of total fat and unsaturated fat.  Additionally, we typically eat way too much meat rather than consuming the recommended 3-ounce serving size.

A recent nutrition research study continues to add fuel to this debate on meat consumption and weight gain.  This new study examined the relationship between protein intake and body mass index and compared animal protein to plant protein intakes in volunteers enrolled in the Belgian National Food Consumption Survey.  Eating habits were determined by 24-hour dietary recalls from over 3,000 men and women.  In this group of volunteers, animal protein consumption was nearly twice as high as plant protein consumption. Meat and meat products made up the majority of the animal protein consumption, while cereals and cereal products made up the majority of plant protein intake.  A look at the relationship between different protein intakes and body mass index revealed:

• As animal protein intake increased, body mass index became greater in men.
• Also in men, eating greater amounts of animal protein resulted in greater waist sizes.
• In men and women, an increasing level of plant protein consumption was linked to both a lower body mass index and a smaller waist size.

This new research study continues to suggest that the consumption of animal protein is linked to an increase in body mass index and waist size, putting individuals at risk for becoming overweight or obese.  In contrast, altering our eating habits to include greater amounts of plant proteins might help support a healthier body weight and reduce our risk of becoming overweight.  Unfortunately, this study's summary does not indicate whether this analysis was done such that it adjusted for caloric content of these foods, as this could impact the final conclusions.  Nonetheless, previous research that did make this adjustment still suggested that red meat consumption was linked to weight gain.  Reducing the amount of animal protein we consume or making healthier choices in the animal proteins we choose to consume can be an important part of our fight against obesity.  Fortunately, the U.S. Department of Agriculture (USDA) recently announced that the 40 most popular meat products will be required to carry a nutrition facts panel.  The nutrition facts panel will include the total calories and grams of total fat and saturated fat the product contains and any product that lists a lean percentage statement (e.g. "80% lean") on its label also must list its fat percentage.  This information will make it easier for all of us to choose meat products that fit into a healthy diet.

Healthy, Hunger-Free Kids Act Signed!

As I have mentioned in several previous blogs, childhood nutrition is in need of some major improvements.  This is particularly true in regards to the foods provided to children as part of their lunch, vending machine, and a la carte options offered at schools and daycare facilities.  On Monday, the Healthy, Hunger-Free Kids Act of 2010 was officially approved and signed.  Hopefully, this will be a major step in the right direction towards improving childhood nutrition and decreasing childhood obesity.

The Healthy, Hunger-Free Kids Act sets forth a number of goals and guidelines, some of which include:

• Giving the U.S. Dept. of Agriculture (USDA) the authority to set nutritional standards for all foods sold in schools during the day.  This includes school meals, vending machine options, and a la carte options.
• Aids in the establishment of local 'farm-to-school' networks and school gardens in an attempt to focus on fresh, locally grown foods.
• Sets basic standards for school wellness programs that include nutrition education and physical activity.
• Requires school districts to be reviewed every three years to see if they have met new nutritional standards.
• Requires schools to make nutritional information on school meals more available to parents.
• Provides additional funding to schools that meet the updated nutritional standards.

While updated nutritional standards do not appear to have been developed or released yet, a sample menu suggests that healthier options like more fruits and vegetables, more whole grain foods (whole wheat spaghetti, whole wheat dinner rolls, etc.), more low-fat replacements (low-fat salad dressing rather than regular salad dressings), and leaner protein products (turkey, fish, etc) will be emphasized. Although changes will not appear overnight, this new piece of legislation has the potential to make real improvements in childhood nutrition and wellness that will hopefully lead to reductions in childhood obesity.  You can download a fact sheet that provides more information as well as a sample menu at Let's Move.

Eat Plenty of Vegetables Rich in Alpha-Carotene!

Most, if not all, of us have been told as children to "eat your vegetables so you can grow up strong and healthy" and research continues to show us that eating our vegetables has many benefits.  Vegetables are typically rich in nutrients, low in calories, and contain many health-supporting antioxidants.  One such anti-oxidant is alpha-carotene.

A nutrition research study published a few days ago in the Archives of Internal Medicine examined the possible link between alpha-carotene and the risk of death in over 15,000 adults who took part in the Third National Health and Nutrition Examination Survey Follow-up Study.  At the beginning of the study blood samples were collected from study volunteers, who were then followed for about 14 years.  The study researchers measured blood levels of alpha-carotene and analyzed the link between alpha-carotene levels and risk of dying.  The study investigators reported that higher levels of alpha-carotene were linked with a lower risk of dying from all causes.  Specifically, compared to individuals with low levels of alpha-carotene (0 - 1 micrograms/dL), individuals with alpha-carotene blood levels of:

• 2 - 3 micrograms/dL showed a 23% reduction in the risk of death from any cause
• 4 - 5 micrograms/dL had a 27% reduced risk of death
• 6 - 8 micrograms/dL were at a 34% reduced risk of dying from any cause
• 9 micrograms/dL or more had a 39% reduced risk of death

This new study clearly shows a potential link between higher blood levels of alpha-carotene and a lower risk of death during the study's 14-year follow-up, suggesting that higher alpha-carotene levels might be important for living a longer, healthier life.  This is also supported by the lower risk for death specifically due to poor heart health observed in this study.  As you might expect, higher alpha-carotene blood levels can be obtained by eating more foods rich in alpha-carotene.  These include orange and dark green-colored vegetables like carrots, sweet potatoes, winter squash, broccoli, green beans, spinach, collard greens, kale, and romaine lettuce.

According to current recommendations, adult men and women should eat anywhere between 2.5 to 3.5 cups of vegetables daily depending upon specific needs.  Despite this many of us rarely consume enough vegetables each day.  This new study continues to impress upon us the importance of eating plenty of vegetables each day.

Are you eating all your vegetables?

High Cortisol Levels Increase Calorie Intake

Cortisol is an important hormone produced by our adrenal glands.  Under normal circumstances, cortisol plays an important role in blood sugar health, maintenance of healthy immune function, and much more. However, stress can cause a chronic elevation of cortisol, which then can have a variety of negative health effects.  Chronic stress has also been implicated in the risk for obesity. 

A recent nutrition study explored the relationship between cortisol levels and dietary habits in overweight and normal weight women.  In this study, 127 overweight women and 21 normal weight women had their cortisol excretion rate measured over a 24-hour period.  The relationship between the cortisol levels and information collected on dietary intakes were then analyzed.  The researchers reported that:

• Obese women excreted substantially higher levels of cortisol than women maintaining a normal body weight.
• Regardless of the volunteers' body mass index, higher levels of cortisol were linked to larger waist sizes. 
• Higher consumption of carbohydrates, fats, and overall calories was linked to higher cortisol levels in obese women.

These research results continue to suggest a possible link between chronic stress and obesity.  Because the study summary did not discuss stress, it is unclear whether stress might have been involved in the poor dietary choices of the overweight women.  Since long-term elevations in cortisol can be a sign of stress, it is possible stress might be one of the factors related to the study observations.  Nonetheless, this study indicates that elevated cortisol levels, whether from stress or some other reason, might have a major impact on our dietary habits such that we tend to eat more foods high in calories, high in fats, and high in carbs.  These foods, particularly those high in fats and calories, can have a major negative impact on our efforts to maintain a healthy body weight.  Keeping cortisol levels within a normal range, perhaps be reducing stress, might be one way to help maintain a healthy body weight.

Fast Food Nutrition Still Needs Improvement!

In the national effort to reduce childhood obesity, there has been a large push by a variety of advocates to improve fast food nutrition and marketing.  While this movement has resulted in some commendable improvements in fast food, such as a reduction in the amount of trans fat in fried foods and an increase in more fruit and vegetable options, a new report from Yale University's Rudd Center for Food Policy & Obesity clearly indicates that more still needs to be done.

This new report studied the marketing efforts of 12 of America's largest fast food chains and assessed the nutritional quality of over 3,000 children's meal combinations.  A summary of this new study paints a rather disturbing picture:

Unhealthy foods still the norm:

• Of the more than 3,000 meal combinations analyzed, only 12 met the Yale researchers nutrition criteria for preschool children and only 15 met the nutrition criteria for older children.  That's less than 0.5% of the meals tested!
• Meals purchased by teens averaged 800-1,100 calories, which is about one-half of their daily recommendation.  This suggests that eating at a fast food restaurant puts teens at risk for consuming many more calories than needed.
• At least 30% of the calories from fast food meals came from sugar and saturated fat and a single meal often provided one-half of a child's sodium recommendation.

Healthier options are not emphasized:

• Healthier side dishes are rarely the default or 'regular' side provided with a meal.  The standard, automatically-provided side dishes remain French fries and a soda.
• Fast food restaurants are frequently renaming their portion sizes to give the appearance of being smaller rather than actually providing smaller portions.

Fast food marketing continues to increase:

• The number of fast food advertisements seen by preschoolers and children ages 6-11 in 2009 have increased by about 25-30% on average compared to the year 2007.
• 15% of preschoolers ask their parents every day to take them to a fast food restaurant, while 40% of children 2-11 years of age ask to go at least once per week.
• Over 85% of parents report taking their children to a fast food restaurants at least once per week.

This is important information for everyone, but particularly so for those who choose to dine at fast food restaurants.  It is important to remember that we can choose healthier options when dining at fast food restaurants (or any restaurant for that matter).  For example, one kid's meal that includes 4 chicken tenders + fries + a soft drink provides 645 calories, 906 mg sodium, 63 calories from fat, and 120 calories from sugar. In contrast, by replacing the fries with apple slices and the soft drink with fat-free milk, we cut calories (350 calories) and sodium (515 mg) nearly in half while reducing the amount of calories that come from fat and sugar.  Yale University's Rudd Center for Food Policy & Obesity has established a web site, Fast Food FACTS, where you can learn more about fast food nutrition and your child's exposure to fast food marketing.

Fitness Is Declining In College Students

Most of the time when we think about diet, lifestyle, exercise, and obesity, we think about body weight and weight loss.  While these factors are an important component of being physically fit, we often don't give as much thought to how physically fit we are as a population.

A new obesity and wellness research study (free to download) was conducted to determine if the physical fitness of college students changed over time and, if so, how those changes effected measures of obesity like body mass index (BMI) and body fat.  Nutrition researchers analyzed the results of MicroFit tests from over 5,000 students attending a private Seventh-Day Adventist college where each student enrolled in a physical activity class was required to take the MicroFit test.  Information collected on body weight, body fat, muscle strength, aerobic fitness and more from 1996 to 2008 was analyzed.  Fitness was measured by estimating VO2max, which is a measure of the maximum oxygen uptake during a graded exercise and is considered to be one of the most accurate measures of physical fitness.

The results of this data analysis showed that:

• While there was some yearly fluctuation, physical fitness, as measured by VO2max, declined overall during the 13 years examined.
• Physical fitness declined at a faster rate for male college students (0.812 mL/kg/min) than female college students (0.414 mL/kg/min).
• During the 13 year study period, percent body fat increased in both males (0.513% per year) and females (0.654% per year).
• The proportion of male college students classified as having poor physical fitness increased dramatically, while the number of male students classified as excellent, fit, or fair declined steadily.  Similar, but less dramatic, changes were observed in college females.

Overall, this study showed that both male and female college students are apparently becoming less physically fit and gaining more body fat over time.  One of the most interesting aspects of this study is the study population.  Seventh-Day Adventists are a religious group that stresses a very healthy lifestyle that includes eating a healthy vegetarian diet and getting plenty of exercise.  It has been reported that their lifestyle choices have resulted in a lifespan that is typically about 10 years longer than the average American.  This is reflected in this new study by the fact that the average body mass index of the students was about 24, which falls within the accepted healthy range, while average body fat was only about 12% in male college students and 22% in female college students.

While it is not completely unexpected to see a decrease in physical fitness during the college years due to the college lifestyle of little sleep, skipping meals, too much snacking and too much fast foods, one has to wonder how rapidly physical fitness is declining in the general population where healthy diet and lifestyle habits are not as frequently stressed.  Finding ways to increase physical activity, improve eating habits, and improve overall physical fitness during the college years should be an important part of our fight to reduce obesity.

Reduce Belly Fat By Choosing Whole Grains

Current recommendations from the Dietary Guidelines for Americans 2005 are that we should consume 3 or more 1-ounce servings of whole grains per day to help reduce the risk of several chronic health conditions and potentially support healthy weight control.  Whole grains include cereal grains that consist of the intact and unrefined, ground, cracked or flaked fruit of the grains whose principal components, the starchy endosperm, germ and bran, are present in the same relative proportions as they exist in the intact grain. While whole grains are an important part of our daily diet on their own, recent research suggests that consuming adequate amounts of whole grains each day also improves our overall diet quality.

Although previous research has suggested that whole grain consumption might help support healthy weight control, the impact of the types of grains we consume on body fat is not completely understood.  A recent nutrition study published in the current issue of the American Journal of Clinical Nutrition examined the impact of dietary grain consumption on changes in abdominal visceral fat (fat found around our internal organs) and abdominal subcutaneous fat (fat found under the skin of our belly).  Dietary information was collected from over 2,800 adult men and women who took part in the Framingham Heart Study by the use of a food frequency questionnaire.  Links between grain (whole versus refined) consumption and measurements of abdominal fat volume were analyzed.  The nutrition researchers reported:

• Individuals in the group with the highest whole grain consumption had the lowest amount of visceral fat and subcutaneous belly fat.
• Eating large amounts of refined grains was linked to higher levels of both subcutaneous belly fat and visceral fat.
• Study subjects who consumed at least three servings of whole grains, but still continued to eat large amounts of refined grains did not see any reduction in abdominal visceral fat.

These are very interesting and important findings that can help guide us toward healthier eating habits.  While it is clear that consuming whole grains might have a variety of possible health and nutritional benefits, this new study points out the importance of increasing our whole grain consumption at the expense of refined grains.  The benefits of whole grain consumption on visceral belly fat reduction were only evident when whole grains replaced refined grains in the diet.  So in addition to getting adequate amounts of whole grains in our diets, make sure to substitute those whole grains for the refined grains many of us currently choose.  Instead of dinner rolls made from refined grains, choose whole grain dinner rolls or instead of consuming a sandwich on bread made for refined grains (most white breads), choose 100% whole wheat bread.

Plant Compounds Suppress Inflammation Markers

Obesity has been linked to a low level of chronic inflammation due to the production inflammation-related chemicals by fat cells.  Research has suggested that many of the chronic human health conditions linked to obesity are due to this low-grade chronic inflammation.  Therefore, the concept that reducing the chronic inflammation associated with obesity might help support normal health is receiving a good deal of attention from the scientific and medical communities.  Two recent research studies explored the possibility that natural plant compounds with anti-oxidant and anti-inflammatory properties might help suppress obesity-related chronic inflammation.

In the first obesity research study, investigators examined the effect of resveratrol on the production of inflammation-related chemicals from fat tissue.  Resveratrol is one of the main anti-oxidant and anti-inflammatory polyphenol compounds found in red grapes.  For this study, obesity researchers treated human fat tissue in order to produce an inflammatory response and then treated the fat tissue with resveratrol to determine if it could suppress this artificially induced inflammation.  The study investigators reported that treating human fat tissue with resveratrol suppressed both the induced secretion of several inflammatory chemicals and the gene expression of these inflammatory chemicals.

A second obesity research study examined the impact of lycopene on the production of inflammation-related chemicals from fat tissue.  Lycopene is the chemical responsible for the red/orange color of many fruits and vegetables, including tomatoes.  To evaluate this possible relationship, investigators cultured fat tissue collected from mice fed a high-fat diet as well as human fat cells.  The obesity researchers reported that treatment of fat cells, both mice and human, with lycopene suppressed both the normal production of chemicals involved with inflammation and the artificially stimulated production of these inflammation chemicals. 

Both of these cell culture studies suggest that natural plant chemicals with anti-oxidant and anti-inflammatory properties might be able to suppress the chronic inflammation associated with obesity.  With the high rate of obesity and the link between obesity, inflammation, and human health, methods to reduce obesity-related inflammation could be very beneficial.  Additional studies will be needed to determine if natural plant chemicals like resveratrol and lycopene can have the same anti-inflammatory benefits when consumed and how much is needed in the diet to obtain these possible benefits.  Fortunately, many of these natural chemicals are found in fruits and vegetables, giving us additional reasons to eat plenty of fruits and vegetables.  In addition to being sources of some of these anti-inflammatory chemicals, fruits and vegetables are nutrient rich and low in calories, making them and essential part of a healthy, well balanced diet.

Vitamin D - How Much Do We Need?

Vitamin D has been a hotly debated micronutrient over the last few years.  Current dietary recommendations as set by the Institute of Medicine are that adults up to 50 years of age require 200 International Units (IU) per day, that adults 51 - 70 years of age should obtain 400 IU per day, and adults over 70 years of age should get 600 IU per day.  For purposes of safety the Institute of Medicine has set a tolerable upper level intake at 2,000 IU per day.  Since these recommendations were set, science has continued to explore the health benefits of vitamin D with many of these studies suggesting that much higher doses of vitamin D are needed to achieve health benefits beyond meeting basic nutritional requirements.  The weight of the evidence for a higher daily recommendation has led the Institute of Medicine to re-evaluate their recommendations for dietary vitamin D with a final report due to be released in the very near future.

In an attempt to provide relevant data for the re-evaluation of dietary vitamin D recommendations, a new vitamin D research study aimed at determining the appropriate amounts of vitamin D for health benefits and safety was conducted.  For their assessment of vitamin D the nutrition researchers analyzed previously published research trials on the potential benefits of vitamin D for fractures, falls, heart health, and cancer and on the safety of vitamin D at high doses.  The results of this data analysis showed:

• Fractures - Doses of vitamin D between 482-770 IU per day reduced the risk for non-vertebral fractures by about 20% and reduced the risk for hip fractures by about 18%.  Lower doses of vitamin D did not reduce fracture risk.  Optimum fracture prevention occurred with blood levels of vitamin D between 75-110 nmol/L (30-44 ng/ml).
• Fall Prevention - the risk of falling was reduced by 19% when vitamin D was consumed at doses of 700-1,000 IU per day, while lower doses did not reduce the risk of falls.  Optimum fall prevention was observed when blood levels of vitamin D were between 75-100 nmol/L.
• Non-Skeletal Endpoints - data collected and analyzed from studies on the impact of vitamin D on cancer, heart health, hypertension, and overall mortality suggest that optimum benefits were achieved with a blood level of vitamin D around 100 nmol/L.
• Safety - Elevated calcium levels are typically used to measure vitamin D toxicity.  According to this new report, vitamin D intake up to 100,000 IU per day or blood levels up to about 640 nmol/L had no effect on average blood calcium levels.  While a handful of individual case reports of elevated calcium were identified, all the relevant cases occurred at vitamin D blood levels higher than 500 nmol/L.

This is an important study that might well influence new dietary recommendations for vitamin D.   According to these study results, an optimum blood level of vitamin D for a range of health benefits is between 70-110 nmol/L.  The study investigators indicated that this level can be obtained by consuming between 1,800-4,000 IU vitamin D per day.  This daily consumption amount is substantially higher than the current upper limit of 2,000 IU per day as set by the Institute of Medicine.  However, based on the data from this study, doses much higher than this had no toxicity.  In those cases where elevated calcium was observed, blood levels of vitamin D were 4 to 5 times higher than the optimum levels.  Based on these study results, consuming 1,800-4,000 IU per day appears to have numerous health benefits with little or no risk of toxicity.

In addition to the health endpoints examined in this study, a previous study has suggested that vitamin D might support weight loss. In this study, a vitamin D blood level of 30 ng/ml was associated with a weight loss of about 12 pounds.  A blood level of 30 ng/ml is equivalent to 75 nmol/L and is thus within the optimum range defined by the latest study.

According to this latest study, consumption of 400-800 IU per day leaves about 50% of the adult population with below-optimum blood levels of vitamin D.  It will be interesting to see if the Institute of Medicine changes their recommendation for vitamin D intake and if so to what level.

Eat Your 'Whole Grains'!

The Dietary Guidelines for Americans 2005 recommend that we consume 3 or more 1-ounce servings of whole grains per day to help reduce the risk of several chronic diseases and potentially support healthy weight control.  Interestingly, there was not an official definition of 'whole grains' until one was issued by the U.S. Food & Drug Administration in February 2006.  According to the FDA, whole grains include cereal grains that consist of the intact and unrefined, ground, cracked or flaked fruit of the grains whose principal components, the starchy endosperm, germ and bran, are present in the same relative proportions as they exist in the intact grain. Despite having a better understanding of what constitutes 'whole grains', little information exists on how much whole grain we eat as a population and how it impacts our overall nutrient intake.

A new nutrition research study published in the current issue of the Journal of the American Dietetic Association used data collected in the National Health and Nutrition Examination Survey (NHANES) from 1999 - 2004 to determine the link between consumption of whole grains and diet quality, including nutrient intake.  Data was collected from 7,039 survey participants between 19 - 50 years of age and 6,237 participants 51 years of age or older.  The survey participants were divided into four groups based on their whole grain consumption habits: (1) zero to less than 0.6 servings/day, (2) between 0.6 - 1.5 servings/day, and (3) between 1.5 - less than 3 servings/day, and (4) 3 or more servings/day.  Analysis of whole grains consumption, dietary quality, and nutrient intake showed that:

• When looking at the study population overall, individuals between 19 - 50 years of age only consumed 0.63 servings of whole grains per day on average, while adults over 51 years of age ate an average of 0.77 servings of whole grains per day.
• In adults consuming the most servings of whole grains daily, diet quality and intakes of fiber, polyunsaturated fatty acids (healthier fats), and total energy were substantially higher.
• Micronutrient intake, except vitamin B12 and sodium, was higher in adults consuming the most servings of whole grains.
• Adults eating the highest levels of whole grains consumed significantly smaller amounts of total sugar, added sugar, saturated fatty acids, monounsaturated fatty acids, and cholesterol.

The results of this dietary consumption analysis provide us with a couple of important take-home messages.  First, it is clear that eating recommended amounts of whole grains dramatically improves our diet quality.  This was clear by the increase in the consumption of healthier dietary components like fiber, polyunsaturated fats, and higher amounts of most vitamins and minerals.  Additionally diet quality was improved by the reduction in the amounts of less healthy dietary components like saturated fat, added sugar, and cholesterol.  Secondly (and unfortunately), this new study makes it very clear that the vast majority of us eat no where close to the amount of whole grains that we should.  This lack of whole grains in our diets has a serious negative impact on our overall diet quality.  Based on these study results if we wanted to make one quick and easy dietary change to improve the quality of our diet, it would be to start consuming 3 or more servings of whole grains every day.

How much whole grains do you eat each day?

Maintain A Healthy Body Weight With A Mediterranean Diet

A Mediterranean type diet pattern, which is typically rich in fruits, vegetables, fish, olive oil, nuts, beans, and seeds, with only low to moderate consumption of red meat and wine, has been reported to have a number of possible health benefits.  Some studies have suggested that the possible benefits of the Mediterranean diet might be due to the levels of olive oil consumption in a Mediterranean diet.  In fact, recent research reports that the possible benefits of olive oil might be through a reduction in chronic inflammation.

While research suggests that following a Mediterranean diet plan might support normal human health, the benefits of this dietary lifestyle on obesity risk are apparently less clear.  To examine the impact of the Mediterranean diet on weight gain and obesity risk, nutrition researchers conducted a study in over 103,000 men and over 270,000 women from 10 European countries.  Study investigators collected body characteristics at the beginning of the study and after an average of 5 years and determined the volunteers' adherence to the Mediterranean Diet pattern by measuring their consumption of 9 different dietary components typical of the Mediterranean diet.  The results of this research showed that individuals who stuck to the Mediterranean diet pattern closely maintained their body weight over the 5-year study period.  Compared to individuals who did not comply well with the Mediterranean diet pattern, individuals who complied well were 10% less likely to become overweight or obese.  The nutrition researchers further reported that the low level of meat consumption, typical of the Mediterranean diet pattern, appeared to be the reason for the ability of individuals to maintain their body weight while on this dietary pattern.

Being overweight or obese has been linked to a number of chronic health conditions, which emphasizes the importance of maintaining a healthy body weight throughout life.  A typical Mediterranean diet is rich in fruits, vegetables, nuts, beans, and fish, but low in red meat and wine.  This is in contrast to a typical Western diet, which is generally high in red meat, high-fat foods, refined grains and sweet desserts.  This new research study shows that following a healthier diet pattern might help us each with our weight management goals and reduce the risk for obesity.

Perceiving Our True Body Size

A large part of the fight against obesity revolves around obesity education and obesity awareness.  This involves making us aware of our body weight, exercise habits, eating habits and more and teaching us how to make appropriate changes that will hopefully lead to each of us adopting a healthier lifestyle.

Despite progress in obesity awareness and education, the results of a recent Harris Interactive poll suggests that as a whole, we still do not recognize when we are overweight or obese nor the extent of our body size.  Harris Interactive conducted an online survey between August 17-19, 2010 in which more than 2,400 volunteers answered questions about their body size image and more.  The results of this survey indicated that:

• 30% of overweight individuals think that they are within a normal body size range.
• 70% of obese people believe that they are simply overweight.
• 39% of morbidly obese people believe that they are overweight, but not obese.
• For those individuals who recognized themselves as being overweight, most of them (52% of overweight people and 75% of obese and morbidly obese people) blamed a lack of exercise on being heavy.
• Only 36% of overweight individuals, 48% of obese individuals, and 27% of morbidly obese people felt they ate more food than they should.
• Survey responders believed that weight loss surgery is the most effective weight loss method.

These are rather disturbing survey results that indicate the healthcare industry still has a lot of work to do in regards to educating us about obesity and appropriate body size.  Based on this poll, there is a large population of Americans that do not recognize they have a weight problem or do not recognize the extent of their weight problem.  Without this recognition, it is difficult for any of us to make necessary changes.  The authors of the poll suggest that fat has become the new norm, which if true, is a very unsettling situation.  Knowing your body weight and body mass index is an important part of developing and maintaining a healthy lifestyle.  You can calculate your body mass index for free at many websites, including the National Heart Lung and Blood Institute's website.  What's your BMI?

Higher Calcium & Vitamin D Levels Support Weight Loss

The effect of vitamins and minerals on weight loss has been and remains an active area of research investigation.  Two of the most studied are calcium and vitamin D; however, the results to date have been mixed and inconsistent making the role of the calcium and vitamin D in weight loss somewhat controversial.

A new weight loss study published online ahead of print in the American Journal of Clinical Nutrition further examined this possible relationship.  Weight loss researchers collected and analyzed data from 322 volunteers who took part in the 2-year Dietary Intervention Randomized Controlled Trial.  The results of the weight loss researchers analysis showed that:

• Vitamin D blood levels at the beginning of the study were lower in volunteers with higher body mass index (BMI) scores.
• At 6 months, higher levels of dairy calcium consumption were linked with greater weight loss.  An average of 580 milligrams of calcium per day was linked to a weight loss of about 12 lbs on average, while intake of about 360 milligrams per day on average was associated with a weight loss of about 8 lbs.
• Similar results were observed for vitamin D.  Blood levels of about 30 ng/ml vitamin D on average were also associated with a weight loss of about 12 lbs.
• Each incremental increase in dietary calcium intake was associated with about a 45% increased chance of losing 10 lbs, while each incremental increase in vitamin D blood levels increased the chances of successfully losing 10 lbs by about 70%.

These are excellent results indicating that higher consumption of calcium and higher blood levels of vitamin D, two important micronutrients, might be related to greater weight loss while dieting.  In general, it is very important to make sure you get adequate amounts of vitamins and minerals when dieting since dieting has been reported to lead to insufficient micronutrient intake.  This study not only supports that, but also indicates that getting enough of these two micronutrients might be one key to successful weight loss.  If you are not getting adequate amounts of these and other micronutrients through your regular diet and lifestyle, a good multivitamin/multimineral can be a good way to get your fully daily complement of vitamins and minerals.

Children's School Lunch Choices Need to Improve

It is abundantly clear that there is a childhood obesity problem that appears to stem from a wide variety of issues.  As I mentioned in a previous blog, children utilizing the school lunch program appear to be at an increased risk for becoming obese.  While this might be partly due to the food choices provided to the children, the choices children make while in line at the school cafeteria also plays a part in this growing problem.

A new nutrition research study published in the Journal of Nutrition was conducted to determine if food choices made by school children during lunch met nutrition standards set by the School Meals Initiative (SMI) and the Institute of Medicine (IOM).  For this study, investigators measured food choices and consumption of over 2,000 4th - 6th grade children over a 3-day period using digital photography in 33 schools.  The amount of Calories, fat, saturated fat, calcium, iron, and vitamins A and C were calculated and the percent of children meeting the SMI and IOM nutritional standards was determined.  The nutrition researchers reported that:

• On average, children selected about 760 Calories worth of food, ate about 550 of those Calories and threw the remaining 210 Calories away.
• 77% of the children met the lower limit of the SMI's energy recommendation.
• In contrast, only 16% of children met the Institute of Medicine's recommended energy range with 74% of the children consuming more than the recommended amount of Calories.
• More than 70% of children consumed more than the recommended amount of saturated fat.
• Because children threw more carbohydrate than fat away, they consumed proportionally more dietary fat.
• The majority of the children in the 33 schools tested met recommendations for protein, calcium, iron, and vitamin A.

The results of this study present a mixed bag of positive and negative results.  It is great news that children using the school lunch program are meeting recommendations for protein consumption and intake of a number of vitamins and minerals.  However, these results clearly point out that grade school children are consuming too much food and too much saturated fat.  This excess food and fat consumption might well be one of the reasons why a previous study suggested that using the school lunch program increased obesity risk.   Fortunately, programs designed to improve food choices in the school lunch program are already being installed as part of the nations' fight against obesity.

Exercise & Eat Right To Reduce Menopausal Weight Gain

While many women can probably attest to the fact that they gain weight after menopause, there has been some scientific debate about whether the weight gain and changes in body composition that take place during this time of life are related strictly to menopause or are just another unwanted part of aging in general.

A new research study in Chinese perimenopausal women attempted to clarify this debate.  For this menopausal body composition study, researchers collected data from 438 perimenopausal women between the ages of 44-55 years who took part in a large bone health study.  Body composition information was collected at the beginning of the study and after 9, 18, and 30 months.  Changes in body fat and lean muscle mass were compared between women who remained premenopausal, those who transitioned through menopause and women who were already in menopause at the start of the study.  The study investigators reported that:

• A decrease in lean muscle mass and an increase in total fat mass and trunk fat mass were observed overall during the 30-month follow-up period.
• Age was negatively linked to central obesity (belly fat), such that belly fat increased as the women got older.
• When the information was adjusted for age, menopause was specifically shown to be linked to a decrease in lean muscle and an increase in percent body fat and trunk fat mass.

Overall, this new body composition study showed that though aging in general is related to weight gain, the transition to menopause itself is linked to an increase in body fat, particularly belly fat.  Like many other aspects of the menopausal transition, these changes in body fat distribution have been reported to be due to the loss of estrogen during the menopausal transition.  While hormone therapy has been reported in some studies to decrease obesity in postmenopausal women, hormone therapy comes with its own set of risks.  Developing healthy diet and lifestyle habits remains the best approach to preventing or reducing the impact of menopause on body weight gain and body composition.  Eating healthy foods in appropriate portions and getting plenty of exercise are core to preventing menopausal weight gain.  Starting during the premenopausal years and developing life-long healthy habits is the best approach to maintaining a healthy body weight throughout life.

My easy diet plan is a great way to start developing healthier lifestyle habits and reaching a healthy body weight.  Instead of being punished with hunger, my protein-rich bars and shakes help you feel satisfied and keep you full.  Visit us at www.drtabor.com to learn more and tune in to watch me on QVC September 12th from 1 AM - 2 AM EST!

Don't Make Food Your Reward!

We all experience differences in weight loss success with some of us able to lose weight much easier than others.  In many cases, this can be simply due to differences in the amount of exercise we do; however, some research shows that these differences exist even when the exercise routine is supervised.  The reasons for this are not completely clear, but a new exercise and weight loss study suggests that differences in how we desire food after exercise might play a part in the individual differences in weight loss.

In this new weight loss study, which is free to download, obesity researchers examined exercise-induced changes in the perceived reward value of foods in overweight and obese volunteers.  Study volunteers followed a supervised exercise routine designed to burn 500 Calories per day, 5 days per week for 12 weeks.  The reward value of food was measured in each study volunteer using a computerized procedure that measured liking, wanting, and food preferences based on photographic food images that showed foods with different tastes and fat contents. Study volunteers were classified as Responders (exceeded predicted loss in fat mass) and Non-Responders (lower than expected loss in fat mass) and differences in their perceived reward value of food after exercise were examined at the start and end of the study.  The obesity researchers reported that:

• Responders lost an average of about 11 lbs in 12 weeks compared to Non-Responders who lost an average of 4 lbs.
• After a bout of exercise, the liking for all foods remained unchanged in Responders.  In contrast, Non-Responders experienced an increase in their liking for all foods immediately after an exercise session.  This perception in reward value of foods was similar at both the start and end of the study in both groups of volunteers.
• After an exercise session, Non-Responders showed a greater desire for high fat foods than Responders.
• Non-Responders experienced an increased preference for high fat, sweet foods immediately after exercise, while Responders showed an increased preference for low fat, non-sweet foods after exercise.

This is a fascinating study that concludes that overweight and obese individuals who show an increased desire for food, especially foods high in fat and sugar, immediately after an exercise session lost less weight.  One of the interesting aspects of this study is the fact that even individuals who successfully lost weight showed an increased desire for food; however, their preferences were for non-sweet, lower fat foods.  The obesity researchers also indicated that the preference for high fat, sweet foods after exercise in Non-Responders was only seen at the beginning of the study, suggesting that exercise if maintained regularly might be able to eventually overcome these preferences.  It is apparently unclear why some individuals experience a heightened desire for foods after exercise while others don't.  The study authors suggested that differences in brain hormones after exercise might sensitize some individuals to food and food cues.

This study shows the importance of not making food a reward for weight loss or exercise.  Of course, it makes sense to not use food as a reward because we often eat more than planned and defeat the purpose of exercise.  However, knowing that exercise might increase our desire for food makes it even more important to set up other reward systems.  For example if you meet an exercise goal, plan a relaxing day at the pool, beach or at the spa. Just make sure it is not food!

What reward system do you use?

Exercise in an important part of any good diet or weight loss plan.  My easy diet plan, which uses delicious high protein, low-glycemic bars and shakes, recommends walking 30-45 minutes a day as a great way to start exercising.  Tune in to watch me on QVC September 12th from 1 AM - 2 AM EST!

Lose Belly Fat - Support Normal Blood Vessel Health

Just a few days ago, I mentioned the fact that excess belly fat is dangerous to our health.  These research studies have reported that excess belly fat (also called abdominal obesity) has been linked to poor heart health, poor blood sugar health, and overall mortality.  Previous studies have implied that belly fat gain might be linked to poor heart health by inducing changes in blood vessel health and the ability of blood vessels to stretch normally.  However, this potential link between belly fat and blood vessel health was unclear.

In an attempt to start better understanding the potential interaction between belly fat and normal blood vessel health, heart health researchers examined changes in blood vessel health during a short-term belly fat study (free to download).  For this study, the investigators recruited 43 healthy volunteers with a normal body weight and assigned them to either (1) maintain their weight for 16 weeks or to (2) gain weight for 8 weeks and then lose weight during a second 8-week period.  Changes in the ability of arm blood vessels to stretch and relax were measured at the beginning of the study, after weight gain and at the end of the study.  The heart health researchers reported that:

• Volunteers assigned to gain weight gained about 9 lbs on average over 8 weeks with over 80% of the weight gained as fat.
• In study volunteers that were asked to maintain their body weight, blood vessel health remained normal and unchanged.
• Volunteers who gained weight and belly fat developed poorer blood vessel health with substantial loss of blood vessel stretchability.
• Weight loss after the short-term weight gain resulted in a return to normal blood vessel health.

This is a fascinating study indicating the importance of maintaining a normal body weight or losing excess belly fat  for the support of normal blood vessel health.  According to these current study results, even a modest belly fat gain like seen during vacations or around the holidays can negatively impact blood vessel health.  Fortunately, losing this excess belly fat helped support normal blood vessel health.  While this study shows the possible impact of belly fat on normal blood vessel health, it also raises some interesting questions that will likely be the focus of future research studies.  For example, what happens to normal blood vessel health during long-term (over several years) weight gain, which is typical in many of us?  Also, can losing weight after years of carrying around excess belly fat still help with the support of normal blood vessel health and if so, to what extent?  And, how does weight cycling effect normal blood vessel health.  I look forward to seeing the answers to these types of questions in the future.
