In Jiangsu, a Mr. Jiang suddenly felt weak and weak. After going to the hospital, he was diagnosed with nephritis. Mr. Jiang is also a fitness expert. In order to build a perfect figure, he usually consumes a lot of protein every day, which leads to the overload of the kidney. This leads to nephritis, so too much intake of protein will definitely lead to nephritis? This matter is still uncertain. The doctor said that if the daily diet is enough to meet protein's needs, there is no need to take in extra food. 65 grams of protein per day can meet the basic needs of the human body, but protein can't absorb it. Is the doctor right or wrong? The safety of protein is also a problem that we should pay attention to. Whether the protein powder we eat meets the national safety regulations is something we should pay attention to at ordinary times. Lack of protein will lead to the following problems. The balance of body fluids may be affected. For women, menstruation is prone to imbalance and even affects the success rate of pregnancy. Without protein, women's breasts are prone to deformation and their abdomen is prone to protrusion. For men, the kinetic energy of sperm decreases, the quality of sperm decreases, and the speed of sperm production decreases, which will affect the level of sex hormones and lead to a decline in sexual desire. The growth and repair of muscles are strongly inhibited, and the obvious decline of muscle strength can easily lead to anemia. Once the skin is cut by a knife, the wound will heal slowly. Protein deficiency may lead to hair loss. Hair is made of protein. If you don't get enough protein in your diet, it will probably become dry, yellow, slender and fragile. A very low protein diet may lead to hair growth restriction and even hair loss. Therefore, women should consume at least 55g of protein and men should consume at least 65g of protein. If you have indigestion, if you are a vegetarian, if you don't eat enough staple food, if you need to gain muscle, if you are in the second and third trimester of pregnancy and breastfeeding, you need to increase the number. For breakfast, lunch and dinner, it is best to have high-quality protein, which should be supplemented appropriately when adding meals in the afternoon. The cheapest, best quality and convenient source in protein is eggs. It is best to eat an egg every day. If there is no doctor's advice to control cholesterol, people who need to supplement protein don't have to worry about eating 2-3 eggs a day in the short term. No matter what kind of tonic or health care product is suitable, once it exceeds the amount needed by the body, it will definitely affect the health of the body, and the fitness plan may not be suitable for everyone. Everyone's physique is different, the food they need is different, and their energy is different. If you want to keep fit, let professional fitness instructors make plans according to their own actual situation, instead of following other people's suggestions and paying more attention when finding the right one.
