I think the main use of epidemic is that the media tends to sensationalize things. They like to make it sound like a disease that is spreading, and it isn't. It is all about personal responsibility and being conscious of our dining decisions.
We focus on what we like, instead of what our body needs. Food is a source of comfort, not a source of nourishment. We say we are hungry because we caught a whiff of someone else's hamburger instead of actually being hungry. We are a culture where food is readily available, and we don't keep in mind the affect it will have on our bodies. Not in the way we look, but the actual internals of what it changes.
Foods can be favorites, just like movies can be favorites and that is a problem for most people. Mainly because those favorites generally revolve around grease and preservative soaked foods. People crave hamburgers, and rarely spinach. These are the people that help the report have the affect that it has. So, there is something to blame: The restaurant industry. But placing the blame entirely on that isn't right. We can choose not to have those foods, and if enough people don't want the bad food they offer, they will begin offering healthier options.
It is tough, and most people don't want to spend the time thinking about what they put in their bodies. That is why a site like traineo with motivation and support really helps. Remind us lazy people where we actually stand with our diet.
