A diet containing a lot of protein is involved in the development of osteoporosis. Processing excess protein requires calcium that the body takes from the bones. Try to ask any 14-year-old boy what he would prefer - whether he would be very tall or live longer. It is very likely that he will choose the first one. Already in 1930, research with laboratory animals has shown that a diet containing large amounts of protein can promote growth and accelerate adolescence. At the same time, it also shortens the average life expectancy.
