Bob Barefoot is a chemist who has published several scientific research articles on analytical chemistry and mineral diagenesis. Bob Barefoot is the author of "The Calcium Factor" and "Death By Diet". Bob Barefoot researched enhanced hydrocarbon extraction in the petroleum industry and metal extraction in the mining industry, for which he obtained numerous international patents, and is still active. His use of biochemistry in these fields led him to research the relationship between disease and nutrition, writing two books and appearing as guest speaker at health conventions and on radio and TV talk shows.

Bob Barefoot gives a detailed technical defense to the concept that degenerative diseases are caused by mineral and vitamin deficiency. Scientific evidence provided by some of the world's most renowned scientists is tied together into one cohesive scientific argument that demonstrates that nutritional deficiency is the cause of many diseases.

Although Bob Barefoot has been publicly claiming for more than two decades that nutritional deficiency, especially calcium, is the cause of many degenerative diseases, it has only been recently that medical journals (New England Journal of Medicine and the Journal of the Medical Association) have been quoted in the popular press (Readers Digest, New York Times and U.S. World News Report) as validating that "the humble mineral calcium plays a major role in health and well being". This means that nutrition is finally being recognized and that the medicine of the 21st century should include nutritional therapy.
