Most of us enjoy a
drink but know that there are many drawbacks, and we are all becoming more and
more aware of the negative impact it can have on our health if we consume too
much. However, very little has actually been known about the impact of chronic
alcohol consumption on survival rates.
That is until now, as
researchers in Finland have bred rats to either prefer alcohol or to avoid it,
and the results were astonishing. Rats that were genetically predisposed to
avoid alcohol had a death rate three times higher than those that preferred
alcohol.
There has long been
some awareness of genetics being at play when it comes to alcohol consumption,
as tendency towards alcohol abuse can often be genetic, while some people
appear to carry genes that make them unable to tolerate alcohol. More research
will certainly be needed, but it’s safe to say that we shouldn’t all begin
binge drinking with the idea that we will live longer if we do. What the
discovery actually suggests is that having genes that makes us like alcohol is
no bad thing.
