Causing heart attacks
& strokes is one of the most common ways in which alcohol kills people; and yet the belief
which gives reassurance to many alcohol drinkers is that ‘alcohol in moderation
is good for the heart’. This shows how successful the alcohol industry has been
in shaping public opinion.
Faulty
methodology of studies which make this claim:
If one wants to study the
impact of light alcohol consumption, one must compare those who drink in small
quantity with those who have never taken alcohol (abstainers). However, in most studies which claim beneficial effect of
light alcohol use, past alcohol users (who would have usually quit alcohol
because of it having royally screwed up their health) were included in control
group rather than taking only life-time abstainers. Many systemic reviews have
shown that when you remove such bad quality studies and analyse only the good
quality studies, this claim doesn’t hold true. Eg. In a recent meta-analysis of
87 previous studies on this issue, which analysed the data of 39,98,626
people, after controlling for various quality-related study characteristics
- no significant reduction in mortality
risk was observed for low-volume drinkers (RR = 0.97, 95% CI [0.88, 1.07]).1
Any guesses - how come so many studies
chose a faulty methodology? How come none of the investigators realised that
people with bodies severely damaged due to alcohol were on the control side? Either
they had low IQ or they had decided before the study what conclusion they
wanted to reach. I leave the judgement to you.
Influence of alcohol Industry in
shaping public opinion:
It might interest you to know that
‘International Centre on Alcohol Policy’ is funded by the major alcohol
producers of the world. A lot of ‘gyan’ on alcohol which you or your doctor get
to read could have been funded by them. Two major ideas ICAP tries to propagate
are:
a) Drinking alcohol is not problematic,
only certain drinking patterns are problematic
b) Alcohol industry (which pursues
aggressive marketing to get youngsters hooked on to it) is not at fault, but
the people who drink irresponsibly are at fault.2
Even if we assume the claim of benefit
to heart to be true, its important to keep following things in mind:
What is exactly meant by moderate
consumption:
The industry
uses word moderation as its very vague and most users assume that what they
drink falls within moderate range. So its good to know that what is being
referred to as moderate consumption is upto two drinks (2 small pegs) a day for
men and upto one drink a day for women.
The claim is not applicable to
atleast Indians:
In a multi-centric
Indian study having a large sample size (11898 men), it was seen that the risk for Coronary Heart
Disease (CHD) increased with even occasional alcohol intake, in Indian
population atleast.3
People don’t get addicted by choice
Continuing to drink in control is not
entirely a matter of choice: A significant proportion of drinkers end up
drinking excessively, though they intended to drink in control. This brings in
a lot of negative consequences for the person and his family. Hence, American
Heart Association writes on its website, ““Drinking
more alcohol increases such dangers as alcoholism, high blood
pressure, obesity, stroke, breast cancer, suicide and accidents. Also, it's not
possible to predict in which people alcoholism will become a problem. Given
these and other risks, the American Heart Association cautions people NOT to
start drinking ... if they do not already drink alcohol”4
Many who start with wish to drink in
moderation end up becoming addicts:
3 of my patients of alcohol addiction
had not taken their 1st drink because some friend had forced them,
but because some great doctor had advised them to start drinking alcohol in
control to improve their health.
There are many better ways to improve
your health than to drink an addictive poison:
If you really are bothered about your
health - regular exercise, healthy diet, etc. is the way ahead.
Even light alcohol consumption leads
to many cancers:
There is now evidence that certain
cancers are caused by even light alcohol consumption: In a meta-analysis of 222 studies it was
estimated that in 2004 worldwide, 34,000 cancer deaths were attributable to
light drinking.5
So next time when your friend
reassures you that its safe to drink in moderation, or when you are thinking of
teaching your teenager son ‘responsible drinking’, or when you are thinking of
giving your dear ones a treat of an alcohol party – do keep in mind this
evidence and the fact that this beloved party drink kills around 30 lakh people
every year, 1 person every 10 seconds.
