Anonymous users2024-02-081. It is generally accepted internationally that healthy adults need grams of protein per kilogram of body weight per day. In China, it is recommended to be grams, which is due to the fact that the protein ** in the diet of our people is mostly vegetable protein, and its nutritional value is slightly lower than that of animal protein.
2. The demand for protein is also related to labor intensity, the higher the labor intensity, the greater the demand for protein. In the supply standard recommended by the Chinese Nutrition Society, men aged 18-45 (weighing 63 kg) who are engaged in very light physical labor should have a daily protein supply of 70 grams; In the case of extremely heavy physical labor, it rises to 110 grams. In people with special physiological conditions, the amount of protein supply also changes.
For example, pregnant women who are 4-6 months pregnant should increase their daily protein intake by 15 grams from the original amount; For pregnant women and lactating mothers who are 7-9 months pregnant, add 25 grams on the basis of the original amount. For patients, adjustments should be made on the basis of the normal maintenance amount, considering the characteristics of their disease, disease resistance and tissue repair needs.
It should be noted that these supply standards are proposed on the premise of sufficient calories, if the calories are insufficient, the protein is forced to oxidize and "sacrifice" for energy. Therefore, it makes no sense to talk about increasing protein separately from heat.

Anonymous users2024-02-07A: The cells in the human body are not static, they are in a constant process of renewal, and the cells that die every day are rebroken down in the human body, and then resynthesized after absorption. According to research, about 300 grams of protein is broken down and synthesized in the adult body every day, which is important for maintaining the body's metabolic needs**.
The protein that adults supplement from their diet every day is mainly to supplement the protein excreted from urine and feces, the protein shed from hair and nails, and the protein shed by epidermal cell apoptosis. Now, according to scientists, the recommended amount of protein per kilogram of body weight for an adult is 1 per day. In other words, for an adult weighing 60 kilograms, the estimated daily protein requirement is around 60 grams to 72 grams.

Anonymous users2024-02-06The amount of protein the body needs per day = body weight (kg). Manual laborers need to add about 20 grams to maintain consumption. One egg contains about 10 grams of protein, and 100 ml of milk contains about 3 grams of protein.
Add some meat and you'll basically be able to meet the needs of the day.
The quantity, type and frequency of protein supplementation are very important, and it only takes 4 to 5 hours for protein to be consumed and metabolized in the body, so protein supplementation should be balanced and cannot be concentrated in one meal.

There is no need to worry too much about the most appropriate amount of protein intake for a day, because you can't count all the protein you eat, so just eat a balanced diet, eat an egg in the morning, and then drink some milk and eat some meat, which can almost supplement a person's protein intake for a day.
