In recent years you have undoubtedly heard many times about diet for longevity, with protocols such as the fasting-mimicking one of Dr. Longo or diets to favor cellular apoptosis or intermittent fasting protocols .
Today, a new study provides the missing piece that explains why food restriction would promote longevity. It also explains why the longest-lived populations on Earth have high-carbohydrate diets.
The problem would not, in fact, be the calories. Instead, proteins should be reduced.
It is the reduction of certain protein foods that are rich in sulfur amino acids that is the real weapon to increase life expectancy. Let’s see why.
REDUCE PROTEIN TO INCREASE LONGEVITY
There are several studies that underline the problem of an excess of sulfur amino acids in the diet, highlight a reduction in life expectancy and an increase in particular in cardiovascular risk.
Cysteine, methionine and homocysteine are the most common in some protein foods. For example, stockfish, soy and wheat germ are the foods richest in cysteine. Meat, fish, poultry, nuts, and grits contain a lot of methionine. Homocysteine is made from foods rich in folate and foods rich in methionine.
According to a new study, published in the Annals of The New York Academy of Sciences by Professors Dhong and Richie , a diet too rich in soy, nuts, meat and fish increases the risk of metabolic syndrome, visceral fat, cardiovascular problems, and is linked to premature aging.
This does not mean excluding these foods, but for example avoiding eating them in large quantities.
Steaks, cold cuts, large rations of fish and soy or soy products should thus be reduced, either by alternating them with dairy products or legumes such as peas and lentils, or by reducing the portions.
In particular, parts of the meat such as breast, less fat and more protein muscle parts, etc. should be avoided or eaten occasionally.
It must be said that for now human studies are only epidemiological, therefore observational.
The great results were obtained in experimentation with guinea pigs. The study authors simply urge caution.
However, it is possible that the protocols I mentioned earlier work on longevity simply because they naturally lead to a reduction in these foods.
