Micronutrients are essential dietary elements required by organisms in varying quantities to regulate physiological functions of cells and organs. [1] [2] Micronutrients support the health of organisms throughout life. [3] [4] [5] In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and dietary minerals.
Selenium is an essential micronutrient for animals, though it is toxic in large doses. In plants, it sometimes occurs in toxic amounts as forage, e.g. locoweed. Selenium is a component of the amino acids selenocysteine and selenomethionine.
Foods with micronutrients can help you maintain bone, brain and eye health and more. A dietitian shares the types of micronutrients, deficiency signs and more.
Micronutrients are nutrients such as vitamins and minerals required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. [1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
Micronutrients are needed in smaller amounts (milligrams or micrograms); they have subtle biochemical and physiological roles in cellular processes, like vascular functions or nerve conduction. Inadequate amounts of essential nutrients or diseases that interfere with absorption, result in a deficiency state that compromises growth, survival and ...
Zinc is a vital micronutrient that plays a crucial role in enzymatic catabolism, immune cell function, DNA synthesis, and various micronutrient metabolisms. In the elderly, low serum zinc levels have been reported, which weakens the immune system, making them more susceptible to infections and increasing their risk of morbidity.
Micronutrients are present in plant tissue in quantities measured in parts per million, ranging from 0.1 [3] to 200 ppm, or less than 0.02% dry weight. [ 4 ] Most soil conditions across the world can provide plants adapted to that climate and soil with sufficient nutrition for a complete life cycle, without the addition of nutrients as fertilizer .
Copper deficiency and toxicity can be either of genetic or non-genetic origin. [8] The study of copper's genetic diseases, which are the focus of intense international research activity, has shed insight into how human bodies use copper, and why it is important as an essential micronutrient. [9]
