Micronutrients are essential vitamins and minerals that are required in small quantities for the proper functioning of the body. These nutrients play important roles in various physiological processes, such as metabolism, immune function, and cell repair. Micronutrients include vitamins such as vitamin A, B, C, D, E, and K, as well as minerals like iron, calcium, zinc, magnesium, and selenium. Research in the area of micronutrients focuses on understanding their specific roles in the body, sources of deficiency, and potential health benefits of maintaining optimal levels. This research aims to identify populations at risk of deficiency, develop strategies to improve intake, and investigate the impact of micronutrient deficiencies on health outcomes. Overall, the study of micronutrients contributes to improving overall health and well-being through a balanced and nutritious diet.
