The importance of protein excessive intake is harmful

The importance of protein too much protein intake is harmful When it comes to protein, many people think that protein intake will make them fat However, a reasonable and scientific intake of protein can help us keep healthy From this point of view, as long as it is appropriate to eat some protein food is good The importance of protein 1 Construct human body: protein is the material basis of all life, an important part of body cells, and the main raw material for human tissue renewal and repair Every tissue of the human body: hair, skin, muscle, skeleton, internal organs, brain, blood, nerve, endocrine and so on are all composed of protein, so diet makes man himself Protein is very important for human growth and development For example, the characteristic of brain development is to complete cell proliferation at one time, and the growth of human brain cells has two peaks The first is when the fetus is three months old; the second is when the brain cells grow violently from birth to one year old, especially from 0 to 6 months old By the age of one year, the proliferation of brain cells has been basically completed, and the number has reached 9 / 10 of that of adults Therefore, the requirement of protein intake for children aged 0 to 1 is very special, especially important for children's intellectual development 2 Structural materials: human body is composed of 10 trillion cells, which can be said to be the smallest unit of life They are in an endless metabolic process of aging, death and regeneration For example, in young people, the epidermis is renewed once every 28 days, while the gastric mucosa is renewed in two or three days So if a person's protein intake, absorption and utilization are good, then the skin is shiny and elastic On the contrary, people are often in a sub-health state After tissue damage, including trauma, can not be timely and high-quality repair, will accelerate the decline of the body 3 Carrier transportation: maintain the normal metabolism of the body and the transportation of various substances in the body Carrier protein is very important to maintain the normal life activities of human body It can carry all kinds of substances in the body For example, hemoglobin transports oxygen (red blood cell renewal rate of 2.5 million / s), lipoprotein transports fat, receptors on cell membrane and transporters So, what are the protein rich foods? What to eat for protein supplement 1 Dairy food and dairy products Such as milk, goat's milk, horse's milk and so on, all belong to livestock's milk These milk contain a lot of protein, of which milk contains the most protein It can be said that skimmed milk powder has the highest calcium content and almost no fat content, so the milk made from skimmed milk powder is the best source of protein and calcium for adults to keep slim 2 Meat food There is a wide range of meat for livestock, such as cattle, sheep, pigs, dogs, chickens, ducks, geese, quails, ostriches and so on All these meat products belong to livestock meat This kind of meat contains amino acids needed by human body, so the nutritional value of animal protein is higher than that of plant protein And in all animal protein, because the protein of milk and egg has the characteristics of easy digestion, complete amino acid types, not easy to cause gout attack, so it can be said that its nutritional value is the best of all protein foods 3 Egg food When it comes to foods with high protein content, egg food is even more advanced Whether it's eggs, duck eggs or quail eggs, the protein in the yolk is slightly higher than the protein The study found that egg yolk contains six times more calories than protein, so egg yolk is also a high calorie food So many people regard egg as the best choice to lose weight It can not only provide nutrition, but also help us to lose weight At last, I would like to remind you that too much protein intake is harmful The harm of excessive protein intake Too much protein is stored in fat cells or excreted in urine So yes, excess protein will turn into fat! Don't forget, too, that meat contains more calories and saturated fat than other forms of protein This leads to weight gain and health problems Other risks of overeating protein, especially too many animal meat, include increasing the burden of the kidneys and the heart, and a higher incidence rate of cancer (plants and nuts proteins protect the heart) Protein is an essential nutrient for our health It should be a scientific supplement Editor in charge: Ma Zhixue
