Higdon (Linus Pauling Institute, Oregon State U., Corvallis) lucidly presents research-based information on 27 essential nutrients: their function, deficiency, disease prevention and treatment, sources, and safety. Appendices include nutrient-nutrient and drug-nutrient interactions, a quick reference to diseases, a glossary, and the Institute's prescription for healthy living (including a much lower recommended daily allowance of vitamin C than the late Nobel Prize winner controversially advocated). The title page incorrectly shows Health implications and intake recommendations as the subtitle. Annotation ©2003 Book News, Inc., Portland, OR
