Cancer is a disease that can affect many different body parts. But no matter which body part is affected, cancer always involves cells that, due to various causes, go through genetic changes such that they start to proliferate wildly. In most forms of cancer the expanding masses of cells form tumors that eventually push against and invade neighboring tissue, disrupting body systems. In the course of time they may metastasize, travel via the blood or lymph to another part of the body where they set up new colonies that in turn grow and invade tissue. Even though terminal diseases such as cancer rely on genetic factors, a healthy diet can be designed specifically for preventing disease and effectively implemented into a person’s lifestyle and should therefore be utilized by everyone who wishes to decrease his or her odds of promoting cancer.The food that a person ingests often determines whether or not that person is at risk to have or develop cancer. Certain foods promote different cancers in different parts of the body. Diets high in animal protein especially promote cancers of the liver, large intestine, kidney and breast. Diets high in total fat (animal as well as plant - based) are particularly linked to cancers of the large intestine, prostate, breast and pancreas. Inadequate intakes of plant antioxidant vitamins (beta carotene, vitamin C, vitamin E and many other similar substances) are implicated in many cancers. Food components can prevent cancer by mopping up highly reactive chemicals (free radicals) that act throughout the cancer process inhibiting cell division and enhancing the immune system, especially the so-called "natural killer cells". Food components also reduce the enzyme conversion of chemical carcinogens to active forms, boost the ability of cells to repair any genetic damage and inhibit any ability of cancer cells to break away and invade other tissues. Fruits, vegetables, and grains in general are a...
