What are the seven nutritional pyramids of the human body?

The pyramid of seven nutrients in human body is:

1. Water: Without it, you will die in seven days.

Water is the source of life, and people's demand for water is second only to oxygen. Water is a necessary substance to maintain life, and the substance metabolism and physiological activities of human body are inseparable from the participation of boiling water.

The important component of human cells is water. Normal people's water content is about 70%, infants' weight is about 80%, and the elderly's body is about 55%. You need about 150ml of water per kilogram of body weight, and most of breast milk is water. Water supply should be properly adjusted. You can multiply your weight by 150ml to get the water demand, and then subtract the intake.

Water comes from all kinds of food and drinking water. If you don't take some vitamins or minerals, you may live for a few weeks or get sick for several years, but if you don't have water, you can only live for a few days. Water is beneficial to the chemical reaction in the body, and it also plays the role of transporting substances in the living body. Water plays an important role in maintaining the temperature stability of life.

2. protein: Automatic sewing machine for wounds.

White matter is an indispensable substance to sustain life. Human tissues and organs are composed of cells. The main component of cell structure is protein's growth group, which knows how to repair various enzymes and hormones and regulate biochemical reactions in the body.

The composition of antibodies against diseases, the maintenance of osmotic pressure and the transmission of genetic information are all played by protein. The demand in protein is higher than that of adults, averaging more than two grams per kilogram of body weight every day. Meat, milk, eggs and beans are rich in high-quality protein and must be provided every day.

3. Lipids: the energy pool of the body.

Fat is the main nutrient to store and supply you with energy. One gram of fat provides twice as much heat energy as the same calories, carbohydrates or protein. The composition of nerve tissue technology of body cell membrane can not be separated from it, and fat also plays the role of keeping warm and insulating, supporting and protecting various tissues of visceral joints, and promoting the absorption of fat-soluble vitamins.

5. Vitamins: an important substance to prevent diseases.

Vitamins play an important role in maintaining human growth and physiological functions. Can promote enzyme activity or coenzyme.

6. Minerals: active molecules of nutrition.

Minerals are the main components of the human body. Carbon, hydrogen, oxygen and nitrogen account for about 96% of human body weight. Calcium, phosphorus, potassium, sodium, chlorine, magnesium and sulfur account for 3.95%. Others are trace elements, ***4 1 species, iron, zinc, copper, selenium and iodine that are often mentioned by human body.

7. Dietary fiber: put an end to digestive tract cancer.

There are two definitions of dietary fiber. One is to define dietary fiber as the residue of undigested plants in the digestive system of mammals, including cellulose and hemicellulose. Pectin is resistant to starch and lignification, and the other is from a chemical point of view. Dietary fiber is defined as plant non-starch polysaccharide plus lignin.
