It is true that food has never, been so readily available to the masses. Add to that a myriad of fast food options, easy food preparation, larger portions and an un-ending selection of snacks; it is easier than ever to get food. The ease, at which we have access to snacks and prepared foods high in calorie, is a big contributing factor to the obese epidemic in our country.
You can also add our social activity. Many gatherings and celebrations occur around the table. We also eat when we are lonely or depressed, along with eating when we are happy or rewarding ourselves.
Add to this the fact that healthy foods are more expensive than high caloric foods, it is no wonder obesity has been on the incline for many years.
