Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates , lipids , proteins and fermentation products ...
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 essential elements required by organisms in small quantities to perform various biogeochemical processes and regulate physiological functions of cells and organs. [1] [2] By enabling these processes, micronutrients support the health of organisms throughout life. [3] [4] [5]
Protein is a nutrient needed by the human body for growth and maintenance. Aside from water, proteins are the most abundant kind of molecules in the body. Protein can be found in all cells of the body and is the major structural component of all cells in the body, especially muscle. This also includes body organs, hair and skin.

Nutrient sensing is a cell's ability to recognize and respond to fuel substrates such as glucose. Each type of fuel used by the cell requires an alternate pathway of utilization and accessory molecules such as enzymes and cofactors. In order to conserve resources a cell will only produce molecules that it needs at the time.
Thus, there is gradient from "essential" to completely non-essential, again depending on the condition. Some authors have thus distinguished between genes "essential for survival" and "essential for fitness". [4] The role of genetic background. Similar to environmental conditions, the genetic background can determine the essentiality of a gene ...
