New study finds that food packaging alters what people see as a reasonable serving size, causing people to overeat. Pictures of foods contained on product packaging could make it more difficult to eat healthy by showing portion sizes larger than recommended that include extras, such as toppings or frosting on cakes that are not included on nutrition labels. The results show that manufacturers should be "less misleading" with their packaging. http://www.redorbit.com/news/health/1113413384/packaging-cake-calories-033016/
