Nutriment essential for human body

Nutriment essential for human body
The human body absorbs different nutriment every day, the nutriment is bearing different function. 1,The main function of protein protein is to maintain the growth of tissue, upgrade and repair. Protein is insufficient, children's development is influenced; Adult's physique drops, it is apt to suffer from disease; Difficult to resume after being ill, even worsen, influence the health. Secondly, protein plays a very important role in regulating physiological function of the human body, catalyzing the supersession. Third, protein is a source of the heat energy. Fourth, the humoral immunity of the organism is mainly finished by antibody and complement, form leucocyte and antibody complement and need abundant protein. 2,Main function of the fat is to supply human heat, protect the viscera, keep the body temperature, kind of lipid is the essential composition of cells, save protein. In term of total energy, children's fat delivery volume accounts for 35% of daily total energy, become it for not exceeding 25%. Non- too many, it causes high lipoprotein blood disease even main reason of coronary heart disease to eat high heat energy, fatty, much cholesterol and refined carbohydrate for a long time, some cancers and taking in the fat more, food fibers are few but concerned certainly. 3,The carbohydrate is mainly starch and sugar in the carbohydrate food, 50-70% of daily total amount of heat of people are supplied by the candy. It is not good that the candy is scarce, it is unfavorable to cross the sugar too. 4,Inorganic salts A.Constant element (1)Calcium and phosphorus: The total amount of human calcium is about 700-1400 grams, the total amount of phosphorus is about 400-800 grams, mainly exist in bone, tooth, serum, rickets, richets, osteoporosis take place in the calcium deficiency, hypertension, diabetes incident. Supplementary 800 milligrams of calcium every day. It is in phosphorus for element why in bone is important, or acid, phosphatides nuclear, component. (2)Potassium, sodium, chlorine: Potassium can keep the moisture, regulate permeating to press, maintain the acid-base balance in the body, the adult supports 2-3 grams of potassium every day. Sodium and chlorine are seldom scarce, prevent too much sodium. Too much sodium is apt to suffer from hypertension. (3)Magnesium: The microelement essential to one kind too in our body of magnesium, magnesium can activate the activity of many kinds of enzymes, magnesium participates in 300 multi-type enzyme in the body to urge to react as activator of many kinds of enzymes; Magnesium has inhibitory activity on potassium, calcium passway; Helpful to skeleton and neural muscle, magnesium is the cell structure of bone and essential element of the function, can keep the growth of skeleton and keep. B.Microelement: Iron, Fluorine, selenium, zinc, copper, cobalt, molybdenum, chromium, manganese, iodine, nickel, tin, silicon, vanadium 14 kinds of elements are needed by the human body, lack growth, development, reproduction and life-span influencing people. It can cause iron deficiency anemia to lack irons. Heart disease is related with lacking copper. It can cause simple goiter to lack the long-term excessive iodine of iodine. Fluorine lacks the growth which influences the tooth, apt to suffer from the decayed tooth tooth, it causes Fluorine poisoning and Fluorine spot tooth at most that Fluorine is crossed. All organs of the body include zinc, growing can't lack zinc. 5,Vitamin vitamin whether various living beings keep first low molecular organic compound that normal physiological function need. People lack the obstacle happens, avitaminosis emerges in vitamin, substance metabolism. But it will be harmful to be too many. 6,The fibrous food fiber of food has physiological function of nutrition that other nutrient can't be replaced in the human body. In the past 20 years, the eating habits of the countries all over the world are changing, the total trend regards fresh, high protein, high vitamin, high cellulose as the best choice.
