Like all health books, there are some familiar ideas which should be common sense for all of us now. Avoid chemicals, preservatives, caffeine, nicotine, sugar substitutes, and fat. Marilu's ideas become more extreme for me as she eliminates all dairy, sugar, and meat which I try to limit, but am not interested in eliminating from diet. I was mainly interested in this book for her ideas on food combining, but like all of her chapters, she does not back up any of her ideas with any scientific data which it makes it hard for me to believe anything she is writing is more than just her personal experience. She also lost my support with her opposition to drinking water with meals.
