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.
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).
Food fortification is the addition of micronutrients (essential trace elements and vitamins) to food products. Food enrichment specifically means adding back nutrients lost during food processing, while fortification includes adding nutrients not naturally present. [ 1 ]
By definition, phytochemicals include all nutritional and non-nutritional components of edible plants. [36] Included as nutritional constituents are provitamin A carotenoids, [37] whereas those without nutrient status are diverse polyphenols, flavonoids, resveratrol, and lignans that are present in numerous plant foods.

Scientific analysis of food and nutrients began during the chemical revolution in the late 18th century. Chemists in the 18th and 19th centuries experimented with different elements and food sources to develop theories of nutrition. [1] Modern nutrition science began in the 1910s as individual micronutrients began to be identified.
UNICEF's programming targeting nutrition services amongst disaster settings include nutrition assessments, measles immunization, vitamin A supplementation, provision of fortified foods and micronutrient supplements, support for breastfeeding and complementary feeding for infants and young children, and therapeutic and supplementary feeding.
