It is reported that the protein intake of middle-aged people is equal to smoking

The daily mail recently reported a study by the University of Southern California The study points out that middle-aged people should eat less protein rich animal food such as meat, eggs and milk In the past 18 years, Prof Valter Longo of the University of Southern California recorded and compared the diet and health status of about 6400 people In his study, Professor Longo found that those who like to eat high protein animal food, such as meat, eggs and milk, had twice the risk of death and four times the risk of cancer This figure is equivalent to that of smokers Animal experiments also showed that mice on a high protein diet had a higher incidence of cancer The researchers blame the results on animal protein in egg and milk Animal proteins increase the risk of cancer, stimulate hormone secretion, and lead to aging of human cells According to cell metabolism, diabetes is also associated with excessive protein intake Professor Longo pointed out that there will always be a time in a person's life when there will be cancer cells or precancerous cells in the body The question is, will the cells spread? In Professor Longo's opinion, protein intake will affect the result of this problem Excessive protein intake stimulates the body's IGF1 hormone, which can cause cancer and lead to premature aging Professor Longo suggested that the daily protein intake (grams) of people aged 50-65 should be 0.8 times the kilogram of their weight That is to say, a middle-aged person with a weight of 60 kg should take about 48 grams of protein every day, which is equivalent to two pieces of pork chop Women who take the popular "high protein diet" to keep fit may lose color when they hear the news Celebrity Kim Kardashian and actress Jennifer Lopez are both fans of high protein diet However, the current research also shows that the main impact of high protein induced cancer is limited to people aged 50-65 Before and after the age of 50, the intake of animal protein should not be over cautious This is because with aging and infirmity, the absorption rate of human protein will decline, and the secretion of IGF1 hormone will be much lower than before Professor Longo therefore suggested that the daily protein intake of the elderly after the age of 65 should be 1.2 times the kilogram of body weight The study continues a long-standing critique of red meat and meat products by nutritionists Researchers suggest that people of all ages should get most of the protein they need from fish, beans and bean products, and eat less red meat.
