On The Benefits Of Alcohol
The Lancet recently reported that any heart
gains from drinking alcohol in moderation are likely outweighed
by the harm. Now Danish research shows that drinking alcohol every
day may not protect womean against heart disease at all.
Previous research has shown that moderate alcohol
intake is associated with a lower risk of heart disease, but up
until now most studies have been in men.
Men and women aged 50-65 who took part in this
study were questioned on their drinking behaviour and then followed
for an average of six years.
Women drank an average of five and a half drinks
a week, and men consumed 11.
In men, the risk of heart disease fell significantly
with increased frequency of drinking - with men who drank a little
every day having the lowest risk.
But for women, although drinking on at least
one day a week was associated with a 36% reduced risk of heart
disease compared to those who drank more rarely, the risk was
the same whether women had one drink a week or drank moderately
each day.
Many health experts are now suggesting that many
of these studies are flawed and that while any heavy drinking
is probably coronary-protective, any benefit will be overwhelmed
by the known harms.
The researchers said there could be several explanations
for the differences found between men and women.
It may be hormonal, or related to the type of
alcohol consumed or there may be differences in the way men and
women's bodies process alcohol. Lifestyle factors may also play
a role.
Lead researcher Professor Morten Gronbaek from
the National Institute of Public Health in Denmark said: "It has
been shown that frequency of drinking has a larger role than amount
but this points towards the fact there is a gender difference."
He added that the benefits of alcohol had to
be weighed against the increased risk of cancer and liver damage.
"You wouldn't get any more beneficial effects
from drinking more."
In an accompanying editorial, Dr Annie Britton,
senior lecturer at University College London warned that the study
participants had a high risk of heart disease because of their
age.
And added that the study had a low response rate
and so may not have been fully representative.
She said: "We do not yet know whether cardioprotective
effects accrue over a lifetime or whether, purely from a health
perspective, we should defer drinking alcohol"
Judy O'Sullivan, medical spokesperson for the
British Heart Foundation (BHF) said: "This study does not change
the fact that alcohol should be enjoyed in moderation only, both
by men and women."
Increasing studies on the doubts of alcohol's benefits may actually
lead to scientists to investigate with additional research that
may someday establish that all alcohol, no matter what type, is
toxic for the human body.
"If you are teetotal you should not start consuming
alcohol in order to reduce your risk of developing coronary heart
disease. However, if you enjoy alcohol you should be aware that
the risks of drinking large quantities significantly outweigh
any potential benefits.
