Some Diet foods are high in salt and nitrites that have shown to cause cancer. Also, to reduce the fat and sugar content in a food item, these are replaced with chemicals and food dyes that are widely known to cause cancer. Moreover, these chemicals do not trigger the satiety signals in brain, causing you to eat more of the “Diet” food, thereby increasing your weight.
