What are micronutrients?

Micronutrients are defined as nutrients that are needed in smaller amounts compared to macronutrients, which include carbohydrates, proteins, and fats. This category encompasses vitamins and minerals, which are essential for various bodily functions such as immune response, bone health, and energy production. They play critical roles in metabolism and physiological functions, even though they are required in much smaller quantities than macronutrients.

The significance of micronutrients lies in their ability to support overall health and prevent deficiencies that can lead to various health issues. For instance, vitamins like A, C, D, and minerals such as iron and calcium have specific roles that are crucial to maintaining the body's functions and preventing diseases. Thus, the characterization of micronutrients as those required in smaller amounts is accurate and reflects their fundamental importance in nutrition.
