Document Summary

Cannon be synthesized or synthesized fast enough to meet needs of an animal/human for one or more physiological functions. Research is done by using purified diets to find out if a nutrient is essential. This approach improves confidence in results and is a common research approach.

Nutritional status can have various impacts on health: one can have/experience: Many nutritional deficiency diseases are caused by diets low in an essential nutrient if deficiency lasts for long time, they will cause a suboptimal or lethal health outcome i. e. deficiency in: Iron/folate/ vitamin b12 can cause anemia low circulating red blood cell volume decreases o2 transport, triggers fatigue important at key developmental stages (i. e. pregnancy and infancy)
