The Benefits of Comprehensive Evaluation of Nutritional Status
The human body is comprised of water (60%), plus 60 essential vitamins, 10 essential amino acids, and two essential fatty acids (40%). Essential, in this case, simply means that all 89 of the preceding listed nutrients must be obtained from the diet and not be manufactured in or by ourselves. Fortunately, most of the required nutrients have multiple functions, and to a point, a deficiency of a single nutrient can be masked by other nutrients. Examples of this include two well known causes of anemia, iron deficiency and vitamin B12. We continue to function at reduced efficiency with either deficiency, but severe and prolonged deficiency will cause death. The following graphic, constructed from studies and conducted and the University of Maryland, shows which body systems are affected by 13 of the essential vitamins.
