There are reports aimed at equipping readers to recognize and beware muddled thinking, misunderstandings and deceptions in media stories about health and nutrition and in the claims made by the peddlars of "alternative" therapies. There is a wealth of information on the science of inner well-being and outer beauty. The secret to good health lies in understanding the chemistry involved. Ask Dr. Joe.
