Anutrientis asubstanceused by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies toanimals,plants,fungiandprotists. Nutrients can be incorporated into cells formetabolic purposesorexcretedby cells to create non-cellular structures such ashair,scales,feathers, orexoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as forcarbohydrates,lipids,proteinsandfermentationproducts (ethanolorvinegar) leading to end-products of water andcarbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of theamino acidsthat are combined to createproteins, a subset offatty acids,vitaminsand certainminerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves.Fungilive on dead or living organic matter and meet nutrient needs from their host. Different types of organisms have different essential nutrients. Ascorbic acid (vitamin C) is essential to humans and some animal species but most other animals and many plants are able to synthesize it. Nutrients may beorganicor inorganic: organic compounds include most compounds containing carbon, while all other chemicals are inorganic. Inorganic nutrients includeiron,selenium, andzinc, while organic nutrients include, protein, fats, sugars and vitamins. A classification used primarily to describe nutrient needs of animals divides nutrients intomacronutrientsandmicronutrients. Consumed in relatively large amounts (gramsorounces), macronutrients (carbohydrates,fats, proteins, water) are primarily used to generate energy or to incorporate into tissues for growth and repair. Micronutrients are needed in smaller amounts (milligramsormicrograms); they have subtlebiochemicalandphysiologicalroles in cellular processes, likevascular functionsornerve conduction. Inadequate consumption of essential nutrients, or diseases that interfere with absorption, result in a deficiency state that compromises growth, survival, and reproduction. Consumer advisories for dietary nutrient intakes, such as the United StatesDietary Reference Intake, are based on the amount required to prevent deficiency and provide macronutrient and micronutrient guides for both lower andupper limitsof intake. In many countries, regulations require that food product labels display information about the amount of any macronutrients and micronutrients present in the food in significant quantities. Nutrients in larger quantities than the body needs may have harmful effects.Edible plants also contain thousands of compounds generally calledphytochemicalswhich have unknown effects on disease or health including a diverse class with non-nutrient status calledpolyphenolswhich remain poorly understood as of 2024.
