How alcohol affects the human DNA

British scientists from the Medical Research Council found that acetic aldehyde, which is a byproduct of the body's breakdown of ethyl alcohol, can cause irreversible DNA damage.


It has also been demonstrated that cells have two mechanisms that protect them from the damaging effects of acetaldehyde.

Thanks to special enzymes, the toxin is broken down, but if this is not enough and acetaldehyde accumulates and begins to damage the DNA, then the second mechanism, which repairs the DNA damage thanks to Fanconi proteins, is the stage.


But when there are not enough Fanconi proteins in the body, the body, including the DNA, is irreparably damaged. The same thing happened when alcohol was tested on pregnant mice.

This proves the fact that drinking can lead to an accumulation of acetaldehyde in the body, which is enough to disrupt defense mechanisms.


The findings force us to take a new look at the mechanisms through which alcohol has a detrimental effect on the body. That is why people often show red spots on the body or reddening of the face or an increase in temperature when drinking alcoholic beverages.

Once again, this study only confirms how defenseless our bodies can be against alcohol.
