Query: Outstanding health book for the 21st Century

Dr Ray Strand's book is one of the first I've read that explains the underlying reason so many people in the world are suffering from chronic degenerative diseases -- oxidative stress. He clearly shows how the right diet and the right vitamin, mineral and antioxidant supplements plus essential fatty acids can help bring folks suffering from serious diseases back to health. I've been on the program he recommends for several months and have almost completely recovered from long-standing chronic fatigue syndrome/fibromyalgia. His informative web site, bionutrition.org. has an excellent article on oxidative stress. Thank you, Dr. Strand.
