Micronutrients are essential components of the diet, vital for numerous physiological processes in the body. These include vitamins and minerals that support metabolism, boost the immune system, and promote healthy bone and tissue formation. Each micronutrient has unique roles; for example, vitamin D is crucial for calcium absorption, while iron is essential for oxygen transport. A balanced intake of micronutrients aids in preventing chronic diseases and supports optimal growth, development, and overall health. Ensuring a varied diet rich in fruits, vegetables, and whole foods can help meet micronutrient needs.
