Eat lots and lots of fresh fruits and vegetables. Sounds simple enough, but not too many Americans do it. They contain lots of vitamins, minerals, fiber, and various anti-cancerous substances. Green leafy vegetables are amongst the healthiest of the vegetables, and berries are amongst the healthiest fruit. Corn and potatoes are NOT vegetables.
Corn is a grain, while potatoes and yams are tubers.
The good rule of thumb to use is to only eat fruits and vegetables that you could eat raw if you wanted to. Avoid vegetable and seed oils. These oils contain large amounts of carcinogenic omega-6 fatty acids. The double bonds on these polyunsaturated fats are easily oxidized by oxygen, forming free radicals which can damage DNA and lead to cancer. Furthermore, one of the ways plaque formation in the arteries is initiated is through the oxidation of the double bonds on the LDL molecule, causing it to be attacked by the body s immune system.
