It may come as a surprise to you but few food items that we consume regularly considering healthy are avoided by the nutritionists like Canned soup, smoothies, popcorn and a can of Cola. According to the Daily mail, Canned soup contains plenty of salts. The popcorns are now popular in butter and chocolate form instead of being available in plain whole grain form. A small can of Cola gives you seven teaspoons of sugar. Their regular consumption leads to substantial weight gain and increased risk of Type II diabetes and heart diseases. They can also cause decaying of your tooth.
