It has long been a common belief that people always consume insufficient protein and that eating more protein-rich foods is beneficial. However, recent studies have shown that too much protein is not good for the human body. It is true that “no protein, no life” is a true statement. Because each of our body weight of 55% to 65% is water, water outside the part of 70% to 80% is protein. Our muscles, bones, brain, nerves, hair, nails, blood, hormones, as well as the tissues of the internal organs are almost all made of protein. Insufficient protein will result in such ailments as susceptibility to infection, anemia, abnormal blood pressure, abnormal hormone secretion, damaged or sagging internal organs, accelerated aging and loss of appetite. But do not forget, water can carry the boat, can also cover the boat. 1, protein eat more also “poisoned” 7-year-old birthday this day, his father at noon to take Wei Wei to “KFC” full of fried chicken – a meal. Evening mom and specially for him to do a sumptuous “birthday dinner”, a large plate of fried shrimp almost eaten by him. Unexpectedly, 2 hours later, Weiwei feel bloating, abdominal pain, followed by vomiting, panic, chest tightness, etc., his family immediately sent to the hospital for treatment. After examination, doctors believe that this is not a common intestinal bacterial infection, but too much intake of high protein food caused by “protein poisoning. After timely treatment, Wei Wei’s condition is gradually under control. Normal people in the intake of protein more, in addition to a part of the synthesis of tissue protein, the excess will be converted into sugar and fat storage, or complete oxidation of the release of energy, or by the liver synthesized urea discharged from the body, so the general will not appear “toxicity”. However, for a long time in a state of hunger, or liver, kidney function is lower for people (especially the elderly and children), on the one hand, due to hunger, the body decomposition of protein more, on the other hand, the liver of ammonia and other detoxification capacity is poor, when it suddenly large amounts of high protein intake of food, very easy to cause digestion and absorption obstacles, then in the intestinal bacterial action, will produce a large number of ammonia-containing toxins, resulting in a sudden rise in blood ammonia, the blood will not be able to absorb. Ammonia suddenly rises and spreads to the brain tissue, which in turn causes metabolic dysfunction of the brain tissue, and in the light case (like Weiwei), vomiting, dizziness, panic, accompanied by abdominal pain and bloating and other symptoms, and in the heavy case, it may lead to coma or even death. This is the medical so-called “protein poisoning”. 2, protein can cause cancer can also help cancer Although protein can strengthen the body’s anti-cancer immune system, but it can also help cancer cancer. University of Pennsylvania Medical Center, Dr. Michael research shows that eating too much meat and cholesterol-containing foods, not only prone to atherosclerosis, but also harm the blood circulation, so that the supply of oxygen to the cells is reduced, thus increasing the chance of cancer. Tests on animals and humans have confirmed that limiting the intake of meat, animal fats and butter will reduce the risk of cancer. Dr. Moorman of Holland drew the attention of the Dutch people to the experience of cancer reduction during the Second World War. As a result of the war, the nation’s nutrition was sustained only by rations of coarse grains and vegetables cultivated in their own yards, resulting in an average reduction in the incidence of cancer in the nation of 35 to 60 per cent. Now they speak of the lack of animal protein during the German occupation as “Hitler’s cancer cure”. It seems to be even more evident in patients in whom cancer has been detected, where the cancer seems to grow faster when the patient is given increased protein nutrition. Because cancer cells have a more vigorous metabolism than normal cells, they take large amounts of protein to mold themselves in order to overwhelm their growth. This is a major headache for oncologists and nutritionists.
