It is always better to walk in knowledge than blindly without knowing why. I am one who wants to know why, what, and where.
This book explains the reason why you need and should eat the foods for each Vitamin, Mineral, and more. It explains for each Vitamin, Minerals, Trace Element, Cell Salt, and more the foods that go with each and what function in the body that they help with. Deficiencies are how our body reacts (symptoms) when there is not enough. Simple and to the point.
Symptoms are what tells us there is something wrong that we need to correct. It is so easy to look up your symptoms and start the process of healing by either eating the foods or taking what is needed.
