In addition, the inclusion and interpretation of recent clinical research findings relevant to all vitamins, particularly vitamins A, D, E, K, C, thiamin, folate and vitamin B12 is included, along with an expanded discussion on single-carbon metabolism), implications to neuropathies, and more. Presents complete information about vitamins in a format useful as both a teaching text and desk reference Includes coverage of vitamin-related topics not typically found in general nutrition texts (e.g., enteric microbial biosynthesis of vitamins, global prevalence of deficiencies, diagnosing 'silent' asymptomatic vitamin deficiencies, histories of vitamin discoveries) Contains useful appendices of key reference information (e.g., vitamin requirements of humans and animals, vitamin contents of foods, sources of vitamin information)
