Many foods, especially fruits and vegetables, contain substances that help prevent the formation of cancers, or actively attack existing cancers. This seems to be one of the purposes of food, and is a part of the economy of nature. On the other hand, diets high in trans fat and sugar have been linked to a higher risk of colorectal cancer and other health problems. In the move from animal to vegetable fats, food manufacturers have found it necessary to hydrogenate vegetable oils in order to prevent them from going rancid. However, this process also results in the formation of trans fats, which are therefore present in most processed and fast food. Sugar is added to many foods to stimulate the taste buds, and make us want to eat more of that food.
