balanced diet

Nowadays we can eat many kinds of food.  It is possible in the first world, in our world, but is our diet really healthy?

In this way, there are several studies about this subject which explain how healthy is a balanced diet: it consists of eating meat once or twice per week (chicken is usually the best), fish some days a week, as well as vegetables or fruit every day.

In spite of we eat 4 or 5 times per day, is proved that food we buy in the supermalkets is usually full of quimic prejudicial products. (That sentence doesn't make sense). There are some children and teenagers who are obese, or conversely, develop anorexia or bulimia, which have very negative consequences for their mental and physical health.

We like fast food or cakes so much, despite the fact that we usually know they are unhealthy for us because of their ingredients. What is the real reason we can't stop to eat them regularly?
