Q: This book does not give specific instructions that I could find. It is a compilation of the work and writings of many scientists who have studied the effects people get from certain foods on cancer cells, etc in various parts around the world. The scientific community needs to take it seriously as there are serious risks associated with overdosing. There aren't any good plans here for protecting yourself against food allergies. For all we know, there may be adverse health consequences.
A:
Bad review
