The most important question this book answered for me, was why should someone who eats a sound diet take supplements. I was surprised to learn that, because of all the toxins and stress we are exposed to, a healthy person who doesn't take supplements still runs the risk of getting cancer, cataracts, and other degenerative diseases. The first part of the book deals with the supplements you need to take. The author covers the findings, the dosage and the form you should take. She also discusses 'how much is too much' for each supplement. Then she advices you which foods to avoid (too much iron can make you age, too!) and why. 12 supplements are covered, and three are essential( vitamins E, C and beta carotene), according to the author's research. 5 anti-aging foods are discussed, as well. Even if you are already a cancer patient or aging, the findings indicate that you can reverse the damage, with time. The book was very easy to understand, and fun to read, if you are into improving your health.
