In humans, as in most living things, the natural process of aging begins as soon as we reach maturity, which for us is around the age of 25, and continues until death. This process, which is also called senescence, consists of a progressive, irreversible, and more or less rapid degradation of our various tissues and vital functions.
What is aging?
Aging occurs when damage to cells in the body (such as oxidation, inflammation, and DNA damage, mainly caused by free radicals) adds up, gradually leading to organ failure. and that of the body as a whole. While actual aging only begins at maturity, some cellular damage can begin to accumulate at an early age.

Discovery of a substance that would slow aging, improve health and extend the life
During a study by the University of Minnesota in the United States and recently published in the online medical journal EBioMedicine, researchers discovered a substance, fistein, which fights the aging factors of cells. Fistein would allow them to function better and would help reduce the number of damaged cells in the body.
When they treated old mice with this substance, their lifespan increased, as well as their general state of health improved.
Dr. Robbins, who participated in the study, said: “We found greater activity, better endurance, and greater strength after the use of senolytic substances. »
Fistein, a substance that helps prevent aging
Fistein is a molecule belonging to flavonoid polyphenols, which are recognized for their important antioxidant properties. However, antioxidants have the property of fighting free radicals and are therefore powerful senolytic agents, that is to say, that they have the property of promoting the repair of aging and damaged cells called senescent.
During the study and among the ten flavonoids tested by the researchers, it turned out that fisetin was the one whose senolytic effect was the most powerful in improving the health status of the mice.
Because as antioxidants, they help cells fight external aggressions and promote their repair for optimal functioning.
The benefits of fisetin for the human body
The health benefits of fisetin are countless. On its own, fisetin:
— is an excellent anti-inflammatory
— improves memory and brain function
— regulates blood sugar levels
— increases lifespan
— protects bones, skin, and cells in general against attacks and toxic substances
— helps fight infections
— improves blood flow and pressure
Foods rich in fisetin
To counter the aging of the cells of our body, improve our health, and live longer, we have every interest in consuming antioxidants in general, and fisetin in particular.
To consume antioxidants naturally, simply eat fruits, vegetables, and dried fruits, such as lychees, dates, cherries or figs, artichokes, broccoli, eggplant, or shallots.
As for fisetin, it is found in apples, persimmons, and strawberries in particular.
Adopt a healthy lifestyle
To slow down aging and cellular degeneration, it is important above all to adopt a lifestyle that generates as few free radicals as possible. For it :
— do your best to reduce your stress levels: take the time to relax, sleep well, take a vacation, spend time in contact with nature…
— breathe clean air
— avoid alcohol, drugs, and cigarettes
— avoid industrial food, fast food, and junk food in general
— eat a diet rich in fresh and preferably raw fruits and vegetables, as overcooking foods strips them of many of their nutrients, including flavonoids, and dulling of their color during the cooking process is one of the good indicator.
