The secret, according to French researchers, is to reduce calorie intake and intermittent fasting. This, they believe, increases the levels of certain substances in the body, such as spermidine, and activates the so-called autophagy process (the recycling of cellular components, which plays a key role in preventing aging). In other words, they name a mechanism that increases the stability and survival of cells in any living organism.
“We analyzed,” the scientists write in their article, “an independent group of volunteers who fasted for various periods. Their spermidine levels increased by approximately 50% after only 4 or 5 days and remained elevated during prolonged fasting.”
However, scientists warn that fasting, as well as overeating, can negatively affect the development of age-related diseases.
In 2018, a group of American scientists found that increasing the intervals between meals does indeed improve overall health indicators and increase life expectancy (Science Daily portal). But the Americans claim that the positive effects of intermittent fasting are evident regardless of the caloric content of the food consumed.
And here is another study.
To slow down ageing, it is necessary to “switch off” the so-called TXNIP protein, say scientists at the German Cancer Research Center in Heidelberg. They found that TXNIP controls life expectancy in humans and animals, and its excess accelerates the ageing process. It was found that cells from older people produce significantly more TXNIP protein.
