A question that seems simple, but that triggers endless discussions and alignments between doctors, dieticians and nutritionists: how many proteins a day to eat? Many people think that a high consumption of protein can be harmful to health, when in truth, the studies on the kidney damage that proteins would cause were carried out on patients with kidney disease (hence the theory that proteins damage the kidneys)
. , a very detailed article addresses this issue clearly in light of recent studies.

If it is true that the World Health Organization speaks of a requirement of 0.83 grams per kilo of body weight of protein per day, often approximated to one gram (so, if you think 50 kilos, you should eat 50 grams of protein) , to ensure that we are in balance with respect to the proteins that we break down daily, also allowing us to synthesize new ones. The recommendation, however, is that if you eat 8 grams of protein per day per pound of body weight, these proteins are of high biological quality . 

That is, by favoring animal protein sources and making them follow by vegetable ones such as whole grains and legumes , remembering that to guarantee a complete amino acid spectrum, cereals and legumes must be consumed on the same day, and in the ratio of 2/3 of cereals and 1/3 of legumes.
But let’s get to the studies collected in the article I mentioned earlier, which appeared in Vitals : 1) A study that appeared in  Applied Physiology, Nutrition, and Metabolism explains how those who want to lose weight or maintain a stable body weight, should consume about a little more than one gram to one and a half grams of protein per pound of body weight. This is if you are sedentary but of normal weight. 2) Another study appeared on
