January 14/Pharma Investments, Ventures & Law Weekly -- With obesity rising markedly, reliance on the accuracy of food labeling is an important weight-management strategy. Since people who are trying to reduce their weight are encouraged to choose meals labeled as "lower in calories" or "reduced-energy" in restaurants and supermarkets, it is essential that the listed data are accurate. In a study published in the January 2010 issue of the Journal of the American Dietetic Association, researchers from Tufts University found that some commercially prepared foods contained more calories than indicated in nutritional labeling.
Measured energy values of 29 quick-serve and sit-down restaurant foods averaged 18% more calories than the stated values. Likewise, measured energy values of 10 frozen meals purchased from supermarkets averaged 8% more calories than stated on the label.
