micronut

Micronut is a term that refers to extremely small nutritional components essential for the proper functioning of living organisms. These are distinct from macronutrients, which provide energy and building blocks in larger quantities. Micronutrients are required in much smaller amounts, often in milligrams or micrograms, yet their absence or deficiency can lead to significant health problems. The primary categories of micronutrients are vitamins and minerals. Vitamins are organic compounds that the body typically cannot synthesize on its own and must obtain from the diet. They play crucial roles in a wide range of metabolic processes, including energy production, immune function, and cell growth. Minerals are inorganic elements that are also vital for various bodily functions, such as maintaining fluid balance, supporting bone health, and facilitating nerve signal transmission. Examples of essential micronutrients include vitamin C, vitamin D, iron, and zinc. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is generally sufficient to meet the body's micronutrient needs. However, certain life stages, dietary restrictions, or medical conditions may increase the risk of micronutrient deficiencies, sometimes necessitating supplementation.
