People under 65 who eat a lot of meat, eggs and dairy products are four times more likely to die from cancer or develop cancer. diabetes according to the results of a study from the University of Southern California.
Researchers have studied the impact of consuming animal protein on longevity. They analyzed the medical and dietary data of 6,381 people aged 50 and over who participated in the National Survey of Health and Nutrition Examination (NHANES) which tracks a representative group of adults and children in the United States. United .
The control group consumed an average of 1,823 calories per day, of which 51% was carbohydrate, 33% fat, and 16% protein, two-thirds of which was animal protein.
Valter Longo, director of the Longevity Institute at the University of Southern California divided the other volunteers into three groups. The “high protein” one consumed 20% more calories from animal protein, the “moderate” 10-19% more and the “low” minus 10% calories from protein.
A diet too high in protein increases the risk of death
Scientists found that “high levels of dietary animal protein in people under the age of 65 were linked to a quadrupling of their risk of cancer death and cancer. diabetes, and doubled their risk of dying from any other disease over an 18-year period ”.
In contrast, this same high protein diet appears to protect older people. In those over 65, a high-protein diet reduces the risk of death from all causes by 28%, and cuts cancer deaths by 60%.
Valter Longo suggests that “adults should follow a diet low in protein until a certain age. Then, as soon as they start to lose weight and become fragile, they should increase their intake of animal protein to stay healthy. ”
Concluding his study, Valter Longo said that based on the results of the survey and previous work, “adults should limit themselves to a maximum of 0.8g of protein per day for every kilogram of the body. which corresponds to 48 g for a 60 kg person, and 64 g for an 80 kg person. “
