Minerals are essential nutrients that play a vital role in maintaining overall health and supporting various bodily functions. From strengthening bones and teeth to regulating metabolism, muscle function, and hydration levels, minerals are crucial for optimal well-being. Unlike vitamins, minerals are inorganic elements found in soil and water, which are absorbed by plants and animals, making their way into the human diet. Consuming a variety of minerals-rich foods, such as leafy greens, nuts, seeds, whole grains, and lean meats, is essential for ensuring the body receives the nutrients needed for proper growth, development, and disease prevention.
