Key Micronutrients and Their Food Sources

Micronutrients are essential vitamins and minerals that our bodies need in small amounts to function properly. While they do not provide energy like macronutrients (carbohydrates, proteins, and fats), they play crucial roles in metabolism, immunity, and overall well-being. A diet rich in diverse whole foods ensures adequate intake of these vital nutrients. Below, we explore key micronutrients, their benefits, and the best food sources to obtain them.
