FUMI OSOGAMI^^ Amrican food and culture

As for American food and culture, I have thought why American were more likely to gain weight. Needless to say, the plausible reason is that Amrican food is greasy and high-caloric and large in quantity. Im my opinion, in addition the foregoing, most sweets such as muffins, doughnuts, cupcakes..etc include a lot of suger are cheaper than other foods, so American people are easy to have them. I think that is one of the causes of obesity.
