[Obesogenic food environment explains most of the obesity epidemic]

The food environment has undergone a considerable chance over the past 30 to 40 years. Availability, variation and low costs increase the consumption of foods. Other changes in the food environment include: increase of the high-energy density foods, increased consumption of sugar-sweetened beverages, large portion sizes, large packages, increased variety, increased visibility of foods, and marketing food to children, all known to augment eating and energy intake. Societies should especially protect children from the obesogenic environment by legislation and other regulations. The main targets should be decreasing the consumption of high-energy density foods and sugar-sweetened beverages and returning the sizes of portions and packages to normal.
