Patients who undergo bariatric surgery have nutritional treatment regimens that often entail supplementation of micronutrients as well as reductions in dietary energy intake. However, it is important to place these regimens in the context of normative requirements of micro- and macronutrients. Many of the multivitamin and multimineral supplements advocated for use are based on published dietary reference values (DRVs) for general populations in good health. In this chapter we contrast and compare subtleties between DRVs for adults in the United Kingdom, United States, and Japan. We present data for dietary energy, fats, proteins, carbohydrates, and a variety of micronutrients, including vitamins A, B1 (thiamine), B2 (riboflavin), B3 (niacin), B6, B12, C, D, E, and K, folate, pantothenic acid, biotin, calcium, magnesium, phosphorus, sodium, potassium, chloride, iron, zinc, copper, selenium, molybdenum, manganese, chromium, and iodine. |
