Micronutrients are essential nutrients required by the human body in relatively small quantities but play a crucial role in maintaining optimal health and well-being. These vital elements encompass vitamins and minerals, each with distinct functions necessary for various bodily processes. Vitamins, categorized as fat-soluble (A, D, E, K) and water-soluble (B-complex, C), act as coenzymes, facilitating enzymatic reactions, supporting immune function, aiding in energy metabolism, and contributing to cell growth and repair. They are obtained through a diverse diet containing fruits, vegetables, grains, dairy, and meats. Minerals, such as calcium, magnesium, iron, zinc, potassium, and others, serve diverse functions, including bone formation, nerve transmission, muscle contraction, oxygen transport, and maintaining fluid balance. These micronutrients are sourced from various food groups, emphasizing the importance of a balanced diet. Deficiencies in micronutrients can lead to various health issues, ranging from weakened immunity, impaired growth and development, to more severe conditions like anemia, osteoporosis, and neurological disorders. Thus, ensuring an adequate intake of micronutrients through a well-rounded diet is crucial for sustaining overall health and preventing deficiencies that may compromise bodily functions.
