Eating disorders is often related to habits of people eating items of food that are not generally classified under healthy foods such as fruits, vegetables, milk, and similar stuff. Fast and junk food is also termed under those unhealthy qualities of food. It has been discovered that people who suffer from depression resort to eating unhealthy comfort foods than when they feel happy. 

The January issue of the Journal of Marketing carried a description of several studies conducted by Brian Wansink, the John S. Dyson Professor of Marketing, Applied Economics, and Management at Cornell, and his two colleagues. The studies are geared to provide some insight about the relationship in food and mood of the people.

Wansink suggests that people feeling happy try to maintain or extend their moods in the short term. However, they consider the long term and so turn to comfort food with more nutritional value. While at the same time, people, who are feeling sad or depressed, want to take themselves out of that situation with a quick indulgent snack that tastes good and gives them an immediate relief. This is quite a clear indication that people who feel sad tries to eat junk food. 

We can clearly see that there could be a good connection between what your feeling are and what your mind forces you to eat at that time–it sounds very premature to say, but this may turn out to be one of the reasons why people suffer from bad eating habits–they just do not understand what causes them to love the food, which is not characteristically healthy and should be avoided in general routine. However, we need to mention that the study has clearly provided a path for others to follow, and with more research, we may be able to see the picture in a better way.
