As the saying goes, "winter makes up 39, summer makes up three." Especially with the emergence of the epidemic, more and more people began to pay attention to health. Among them, protein as an important component of all cells and tissues of the human body, while providing energy for the body, it can also improve human immunity. Therefore, supplementing some high-nutrient and high-protein foods is beneficial to our health. So how should we scientifically supplement protein in life? How much do you need per day?

Protein exists widely in animal foods and plant foods, which are specifically divided into animal protein and plant protein. The high quality protein of animal is mainly lean meat, eggs, milk and fish. The vegetable protein is mainly soybean, peanut and sesame. The study found that compared with the simple supplement of animal protein or plant protein, the complementary effect of the two after mixing and matching is better, so pay attention to the combination of meat and vegetable in the food preparation process.

For students who have passed the developmental stage, their protein requirements are close to those of adults. For adults, protein intake is 0.8 grams per kilogram per day. Similarly, if it is a 50 kg adult, then the recommended daily intake of protein should be 40 grams of protein, equivalent to the amount of an egg. It should be noted that, under normal circumstances, through the daily diet of eggs, milk, meat supplement can fully reach about 40 grams of protein demand. If you consume too much protein, it will increase the burden on the liver and kidneys, leading to adverse metabolic changes such as decreased insulin sensitivity and increased urinary calcium excretion. Therefore, if the child is not picky, it is not recommended to give the child additional protein supplements.

For students majoring in sports, some supplements rich in branched-chain amino acids or whey protein can be eaten appropriately during high-intensity special training, which is conducive to physical recovery after exercise. However, it is important to note that when choosing these supplements, it is important to test the safety of the source, and try not to supplement if you are not sure whether it is safe or if the safety is questioned.
