Efeitos da suplementação e da fortificação de alimentos sobre a biodisponibilidade de minerais
Keywords:
biological availability, minerals, supplementary, food, fortifiedAbstract
Strategies for the prevention and control of some nutritional deficiencies, such as anemia and osteoporosis, include food fortification and the use of mineral supplements for at-risk populations. Nevertheless, interactions among minerals may occur and jeopardize the health status of subjects. The objective of this study was to review some possible interactions among minerals when supplementation and food fortification are used. Calcium supplements seem to be related to reduce zinc, phosphorus and iron absorption. In addition, iron excess can decrease zinc absorption and utilization, especially in antianemic formulas. Although several
studies have shown controversial outcomes, mineral supplementation and food fortification must be carefully monitored, in order to avoid promoting other nutritional deficiencies.
