A group of Italian and British scientists identified two factors contributing to premature aging of the body: psycho-emotional stress and a tendency to frequent consumption of alcohol.
The results of the study were published on the site bioRxiv
. Deaths
More than 2,000 people participated in the study, they took samples of urine and blood serum. Scientists have estimated the link between their biological age and nearly 100,000 signs.
It turned out that when aging changes the activity of certain genes. Thus, the methylation profile becomes different – in some parts of the genome (a set of genes), there is a shortage of methyl groups, in others their excess is associated with high levels of consumption. alcohol, anxiety and stress.
Methyl groups – what is it?
They are used in the body to synthesize such important compounds as creatine, choline, adrenaline, etc. The source of these groups is one of the essential amino acids – methionine.
The conclusion of scientists: Alcohol consumption and the state of psycho-emotional stress cause premature aging.
