I changed my eating habits and added moderate exercise, mostly in an effort to lose weight (accomplished) and it did many wonderful things for my health:
1) ideal cholesteral levels now
2) significantly lowered blood pressure and medication needs
3) improved love life (sorry if this is embarassing to folks)
4) totally got rid of depression

I like these books:
The Owner's Manual
The Real Age Makeover

Dr. Michael Roizen, stresses eating "all natural."
He mentioned the following foods as "ideal" on Oprah Winfrey the other day:
1) Olive Oil
2) Tomatoes and tomato sauce
3) Pomegranate juice
4) Spinach
5) Almonds
6) Salmon

I buy the Omega Three Eggs. Somehow I think they taste slightly better.
