Despite macronutrients getting much of the attention in the health industry, micronutrients are the nutrients in which many people may experience deficiencies. In this module, you learn the importance of vitamins, minerals, and phytonutrients. You become familiar with specific micronutrient functions, synergies, and contraindications and learn to identify specific micronutrients they may need more of and how to address potential deficiencies. You also learn how to increase dietary intake, taking into consideration factors such as bioavailability, food preparation, and storage. Current findings regarding micronutrient deficiency and its connection to premature aging, morbidity, and mortality are discussed. Students understand the potential needs and limitations of dietary supplements to address micronutrient deficiencies.
