Increases in Food Availability

Research continues to suggest that our easy access to food is one of the major contributors to the obesity epidemic we are currently facing.  However, it is not entirely clear if there are differences in the availability of specific foods that could be responsible for the increase in obesity.

A new study explored this possibility.  To determine what food categories might be responsible, the study investigator analyzed food availability data from 1909 - 2007.  The results of this analysis showed that on a per person average, the consumption of a number of food categories have increased dramatically. 

• Added Oils - increased from about 16 kg/year to about 39 kg/year
• Meat - rose from 56 kg/year to 91 kg/year
• Cheese - increased from about 2 kg/year to about 15 kg/year
• Frozen Dairy Products - increased from <1 kg/year to nearly 12 kg/year

In addition to these categories, increased availability of sweeteners, carbonated beverages, fruits, vegetables, and fruit juices were seen.  Interestingly, many of the food categories that have become more available over the years are foods that are high in fat content.  Since fat is the most energy-dense macronutrient, the increased availability of these foods might be a major contributor to our increased energy intake and increased incidence of obesity.

In addition to an increase in food availability over time, we have also seen an increase in portion sizes.  For example, cheeseburgers have increased in size and caloric content over time.  According to the National Heart, Lung, and Blood Association, the number of calories in a cheeseburger have increased from 333 calories to 590 calories, an increase of 257 calories.  To view more examples and discover what you would have to do to burn those calories, take their Portion Distortion Quiz.

One of the major keys to healthy eating is portion control.  Since food has become more available and available in larger portions, it becomes more important for all of us to become more aware of proper portion sizes.  Whether you are looking to maintain a healthy body weight or to lose weight, my easy plan is a simple way to make sure you eat the right amount of calories each day.  Visit us at www.drtabor.com to learn more!
