junk food:

The fast food chains now sell a high percentage of fats in its products as well as his drinks have chemicals that affect our health, and many years ago we eat these foods thus has the effect obese people have problems cholesterol or weight exceeds the limits, this looks in greater numbers in schools.

 Most of materials used at McDonald´s are not 100% natural:
Food and drinks have incorporated chemicals products risky for people’s health, from the animals used during production, because they have bad living conditions, besides having a bad diet. The products sold at Mc Donald´s branches contain high levels of fat, calories, sodium, etc, which is not good for our physical condition. for this reasons so I think that you should not sell junk food in schools or not to the public as we are the only ones affected humans.
