What is a micronutrient?

A micronutrient refers specifically to vitamins and minerals that are essential for various bodily functions and are required in smaller amounts compared to macronutrients like carbohydrates, proteins, and fats. Despite the smaller quantities needed, micronutrients play crucial roles in metabolism, immune system function, and overall health. For instance, vitamin C supports the immune system, while calcium is vital for bone health. The distinction is important because it highlights that while micronutrients are not needed in large quantities, they are indispensable for maintaining good health and preventing deficiencies that can lead to serious health issues.

Understanding micronutrients is key to nutrition as they must be obtained from a balanced diet comprising fruits, vegetables, grains, and proteins. This concept differentiates them from macronutrients and emphasizes the importance of consuming a variety of foods to ensure adequate intake of these vital nutrients.
