Swiss scientists have obtained notable results while studying the blood composition of individuals over 100 years old. Research conducted within the scope of the "SWISS100" project, a joint initiative by the University of Geneva and the University of Lausanne, has shown that some biological indicators of long-lived individuals are closer to those of young people compared to 80-year-olds.
According to Demokrat.az, during the study, more than 700 proteins in the blood of individuals aged 100–105, 80-year-olds, and volunteers aged 30–60 were analyzed. It was found that the levels of 37 types of proteins in the blood of long-lived individuals are almost identical to the indicators of the younger generation. This does not indicate a halt in the aging process but rather a significant slowing down of certain important biological functions.
The main differences in the study were recorded in proteins related to oxidative stress, which accelerates cellular aging. The level of this stress was lower in long-lived individuals. At the same time, the quantity of molecules causing inflammation was low, and the levels of proteins regulating metabolism remained stable.
Scientists report that approximately one-quarter of longevity is related to genetics. The remaining part depends on lifestyle factors such as nutrition, physical activity, and social environment. The study results show that a healthy and balanced lifestyle can play a key role in slowing biological aging.
