vitaminAccording to research appearing in the Journal of Nutrition Health and Aging (2011; 15(2): 99-103) looked at the nutritional status of 78 non-institutionalized subjects between the ages of 70 and 75 years over the course of 10 years. At baseline, all subjects ate diets that had adequate (according to the lowest European RDA) amounts of all vitamins, with the exception of thiamin. Over the 10 year course of the study the number of nutrient deficiencies increased. Deficiencies of riboflavin and vitamin A were present in 50% of the subjects and vitamin C deficiency was also present in many of the subjects. The authors of the study concluded that taking a multivitamin may be necessary, even in healthy individuals.
