It is generally believed that healthy adults need 0.8 grams of protein per kilogram of body weight every day. It is recommended to be 1.0g in China, because the source of protein in China's diet is mostly plant protein, and its nutritional value is slightly lower than that of animal protein. The demand in protein is also related to the labor intensity. The higher the labor intensity, the greater the demand for protein. According to the supply standard recommended by China Nutrition Society, male 18-45 years old (weighing 63kg) is engaged in extremely light manual labor, and the daily protein supply is 70g. If he is engaged in extremely heavy manual labor, it will rise to 1 10g. Under special physiological conditions, the supply of protein will also change. For example, if a pregnant woman is pregnant for 4-6 months, the daily intake of protein will increase by15g; Pregnant women and nursing mothers who are pregnant for 7-9 months will add 25g on the basis of the original amount. For patients, adjustments should be made on the basis of normal maintenance, taking into account their disease characteristics, disease resistance and tissue repair needs.
It should be pointed out that the above-mentioned supply standards are put forward on the premise of sufficient heat. If the heat is insufficient, protein will be forced to "sacrifice" energy supply through oxidation. Therefore, it is meaningless to talk about increasing protein without thermal energy.
