English scientists from the medical research Council found that acetic aldehyde, which is a by-product of the breakdown of ethanol in the body, can cause irreversible damage to DNA.

It has also been demonstrated that cells have 2 mechanisms that protect them from the destructive effects of acetaldehyde.
Thanks to special enzymes, the toxin is broken down, but if this is not enough and acetaldehyde accumulates, begins to damage the DNA, then there is a stage of the second mechanism, which restores the damage to the DNA due to Fanconi proteins.

But when Falcone proteins in the body are insufficient, the body, including DNA, irreparable harm. The same thing happened when alcohol was tested on pregnant mice.
This is proved by the fact that drinking can lead to the accumulation of an amount of acetaldehyde in the body, which is enough to disrupt the work of defense mechanisms.

The obtained data force us to look at the mechanisms by which alcohol has a disastrous effect on the body in a new way. This is why people who drink alcohol often have red spots on the body or redness of the face or fever.
Once again, this study only confirms the fact how defenseless our body can be before alcohol.
