Be Careful When Interpreting Size 'Labels'!

Because many of us find it difficult to estimate correct portion sizes and many food providers throughout the world use slightly different portion sizes, we have found it easy to rely on size labels like 'small', 'medium', 'large', or 'extra large' when purchasing and consuming food.  Unfortunately, recent research from the University of Michigan indicates that we as consumers easily misinterpret these size labels.

In a series of 5 studies, nutrition researchers tested consumer's ability to differentiate sizes based on how they were labeled and to determine if the size labeling had an impact on consumption habits.  Some of the observations recorded by these researchers included:

• Labeling a large size as 'small' or 'medium' caused study subjects to perceive them as 'small' or 'medium' rather then recognizing the true size.
• Subjects consumed more food when they perceived large portion sizes to be small or medium based on the size label used.
• Subjects found it difficult to believe that an item labeled 'medium' or 'large' was in fact the size labeled if the item appeared visually small.
• Switching 'small' and 'large' labels caused some subjects to perceive a small item as larger than a large item.
• Individuals less likely to be deceived by the size labels placed on the food were those who were very nutrition conscious.

Overall, the researchers noted that consumers typically underestimate how much they eat and the underestimation becomes larger when the meal size increases.  This can clearly lead to over consumption of food on a daily basis.  Unfortunately, this happens without us realizing it.  Since we generally believe the size label, we tend to believe that we have not consumed too much and feel less guilty about what we are eating.

This is interesting information in the wake of the fast food marketing report, which indicated that some fast food restaurants are simply re-naming their portion sizes to give a smaller appearance rather than actually serving smaller sizes.  For those of us that noticed 'smaller' portion sizes at our favorite fast food restaurant, we might not actually be eating less like we thought because of our tendency to believe the size label.  Becoming more nutritionally aware, particularly about portion sizes, is an important step in our ability to choose foods wisely and fight obesity.

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?

Enhance Your Weight Loss - Read Food Labels

As we all know, exercise and reduced caloric intake are very important aspects of successful weight loss.  However, there are additional weight loss tools that can help with successful weight loss.  These can include things like using safe diet pills, keeping a food diary, partnering with a diet buddy to keep you accountable and more.  A new weight loss study suggests that reading food labels can help with weight loss. 

According to the study summary and a related press release, the weight loss researchers collected information on exercise habits, food label reading habits, and weight loss from volunteers who took part in the National Longitudinal Survey of Youth study.  Analysis of the information collected showed that:

• Women read food labels more often than men
• Women lost weight more successfully than men
• Individuals who read food labels, but did not exercise were more likely to lose weight compared to individuals that exercised, but did not read food labels.
• Consumers who combined food label reading with exercise improved their likelihood of losing weight compared to consumers who just replaced label reading with exercise.

This rather interesting study indicates that reading food labels might be able to enhance weight loss.  Reading food labels is an important part of healthy eating habits.  By reading food labels we are better able to realize what we are putting into our bodies.  The benefits of food label reading in regards to weight loss are likely due to an increased awareness of serving sizes, calorie content of foods, and levels of macronutrients like fat, carbs, and protein as well as levels of micronutrients essential for optimal health.  By reading food labels we become more aware of the nutritional benefits and risks of the foods we are consuming and we begin to discriminate between healthy and less healthy food choices.  Reading food labels is an important step towards increasing our nutritional knowledge and awareness.  So continue to exercise and watch your caloric intake, but also start reading your food labels.

New Menu Nutrition Labeling Laws

On March 23, 2010, section 4205 of the Patient Protection and Affordable Care Act was signed into law.  Section 4205 establishes new requirements for nutrition labeling of regular menu items in chain restaurants, similar retail food establishments, and chain vending machine operators.

This law was enacted as part of our fight against obesity.  According to the background information in a recently released FDA Guidance on the menu labeling, we Americans on average consume one-third of our total daily calories while eating out and in most cases, we are unaware of the amount of calories we consume while eating at restaurants.  By implementing this new menu labeling law, the FDA hopes to provide us consumers with access to nutritional information in restaurants and allow us to make more informed dietary decisions.

For chain retail food establishments (20 or more locations doing business under the same name and offering substantially the same menu items), the new law requires the following:

• Disclosure of the number of calories in each standard menu item on menus and on menu boards.  This includes both food and drink (including alcoholic beverages) routinely presented on the menu and/or menu boards of such restaurants.
• Make additional written nutrition information available to consumers upon request and provide a statement on menus and menu boards that such nutrition information is available upon request.  Should a customer request additional nutritional information, the restaurants must supply the total number of calories, calories from fat, total fat, saturated fat, cholesterol, sodium, total carbohydrates, sugars, dietary fiber, and total protein.
• Provide calorie information for most self-service items and foods on display by posting a sign adjacent to each food item.  This covers such items as foods at a salad bar, buffet line, cafeteria line or other similar self-service facility.

In regards to chain vending machines, operators of such chains must post the calorie content of each article of food sold in the machine in a clear and conspicuous manner.  This only applies to articles that do not allow the consumer to view the nutrition facts before purchasing the item.

While this new law will certainly cover most of the foods at restaurants, it will not cover all of them.  Foods not covered by this new law include condiments and other items placed on the table for general use, daily specials, temporary menu items appearing for less than 60 days per year, custom orders, and food that is part of a market test appearing on the menu for less than 90 days.  Pre-packaged food that lists the nutrition facts and can be viewed before purchase also are not covered by this new law.

While the federal law only went into effect earlier this year, a number of cities and states have previously established menu labeling laws.  It will be interesting to see how this information is both received and utilized.  The idea, of course, is that we will avoid eating less healthy options when we learn just how many calories they provide.  In many cases, menu options contain more that half (sometimes more than all) of our daily energy requirements.  However, it will remain up to us as consumers to use this information and actually choose the healthier option.  This might also impact what restaurants offer to consumers.  The hope is that once restaurants have to disclose the number of calories in their food items, they will start offering healthier, lower-calorie options more regularly.  Whether this strategy will be effective or not remains to be seen, but it has the possibility to help us develop healthier eating habits.
