I have diabetes and heart problems. About 18 years ago I had a double by pass. Why? All of my life I had lived in the USA and except for the last five years there I ate an American Diet. A good way to kill yourself. For the last 20 years I have been eating only steamed or raw vegetables. Limited amounts of fruit because of sugar content and fish. No salt, msg, oil (except for small amts of olive oil]. I do eat small amounts of chicken but no pork, beef, shell fish. I only drink water and no smoking. I feel great at 72 and am planning on making it to 105. As Davis Knowlton said in the above post, eat fresh health food. Forget diets and fads.
