Protein's supplement depends on two aspects. First, age, young people have 1~2 eggs a day, and the elderly have 3~4 eggs a week, and it is best to eat only half a yolk. The second is the amount of exercise. It is generally believed that healthy adults need 0.8 grams of protein per kilogram of body weight every day. 18~45 years old male, engaged in extremely light manual labor, with a daily protein supply of 70g; If you are engaged in extremely heavy manual labor, you need 1 10g.
However, many people always think that eggs are nutritious and can be eaten more. In fact, this concept originated from three years of natural disasters. Protein's intake source is extremely scarce, and now it is rich in materials, and too much food can also provide protein. For example, beef or fish contains about 20g of protein, tofu contains about 10g of protein, and the protein content of/kloc-0 per egg or glass of milk is 1 0g. In addition, in the staple food, the two kinds of noodles also contain 8 ~ 10g of protein. Three meals a day can easily meet human needs. With the current diet, 4~5 eggs per person per week is enough.
Excess protein can't be absorbed and utilized by human body. On the contrary, it will increase the burden on organs such as liver and kidney, and a long-term high-protein diet will also lead to abnormal liver and kidney function. Protein's Poisoning Syndrome appeared, which manifested as abdominal distension, dizziness, weakness of limbs, coma and other symptoms.
Eating egg yolk or egg white is not good. Protein not only exists in egg white, but also contains a lot of high-quality protein, cholesterol, fat, various minerals and vitamins, and its nutritional value is very high. Eating them together provides rich nutrition.
Only people who have poor appetite due to diseases such as infirmity, severe malnutrition and high fever, such as pregnant women, can eat protein powder properly. Nutrition experts say that people who exercise must not eat acidic substances such as meat and eggs immediately after exercise, but should supplement enough water and eat some fruits and vegetables. Add protein after an hour's exercise. Otherwise, the body will secrete too much lactic acid, which will make the body more tired and unhealthy.
