Food portions

It is well known that the United States is the land of plenty. According to the American Journal of Public Health, food portions have increased significantly since the 1970s. Additionally, research conducted by New York University shows that American food portions are much larger than those in Europe.

The more food consumed the larger the energy supply created. This larger energy supply can lead to obesity, a serious problem facing many Americans. However, since many studies analyze their data as correlations it is hard to make any judgments about the causation of the relationship of food portion size and obesity.
