What are the requirements for human nutrients?

Human requirements for nutrients are a number of different types of nutrients needed to maintain optimal health. Nutrients include calories, fat, carbohydrates, proteins, minerals, vitamins and amino acids. Insufficient levels of certain nutrients can lead to various diseases. In developed countries, nutrients are sufficiently serious to cause disease, rare.

The most basic of all nutrient requirements are sufficient calories. Calories provide energy for all body functions and it is important to eat enough calories to give the body enough energy to meet daily requirements. Children in poor countries can develop a condition called marasmus, leading to stunted growth. The body does not have sufficient energy to maintain blood sugar, so it attacks its own protein in an effort to maintain blood sugar.

There are nine essential amino acids that the body needs to synthesize protein. It is important to meet these nutrientsireements because the body cannot these amino acids vyrObit itself. Essential amino acids are valine, threonin, phenylalanine, methionine, leucine, isoleucine, histidine, tryptophan and lysine. Tryptophyn and Lysin are particularly difficult to consume in the right quantity for people on a vegan diet.

Fat is perhaps the simplest of nutrient requirements. It's easy to consume too much fat, but it's the most concentrated form of available energy. Linolic acid, arachidonic acid and linolenic acid are essential fatty acids that the body cannot produce in itself and must be consumed.

Minerals are an important part of nutrient requirements. Some nutrients are required in large quantities, while others are required in such a small amount that it is almost impossible to become insufficient. Food enriched minerals prevent many shortcomings. One example is the Salt table fortified by iodine. Extensive use of table salt iodine almost eLimited iodine deficiency, which can lead to swelling of the thyroid known as goiter and mental retardation if the exact mother is insufficient during pregnancy in iodine.

calcium is a mineral needed for almost all functions in the body, including muscle contractions and blood clotting. Iron is the most common lack of minerals in developed countries and leads to anemia. Women are more likely than men to not reach iron, due to loss of blood from menstruation and increased iron requirements during pregnancy and breastfeeding. However, it is important to be careful when replenishing iron, as iron supplements are the most common cause of accidental poisoning in children in the United States.

non -compliance with nutrient requirements for vitamins can lead to different health conditions depending on the degree of deficiency and vitamin. Lack of vitamin cm can lead to scrotum, vitamin D deficiency can lead to intersections in children and bone softening in adults. People who do not have enough vitamin K can experience slow blood clotting.Low vitamin E levels can lead to anemia and eye damage.
