Alcohol drinking guideline
The Nutrition Taskforce, which I chaired, agonised over
recommendations for alcohol drinking.
After prolonged consideration, we agreed to the statement
“If you drink alcohol, do so in moderation” with intake
recommendation to limit alcohol intake to (or less than) 20 grams per day
for women and 30 grams per day for men.1
The statement has remained the same in subsequent revisions,
although there has been some variation in intake recommendations (up to 40 grams
per day). The variation in the base statement that I would now wish is the
addition of the words “preferably with food”.
In a recent paper published in your
Journal,2
the authors calculate (from undeclared data, much reasoning, and the use of
accepted analytical methodology) very precise conclusions purporting to
accurately represent The burden of death,
disease, and disability due to alcohol in New Zealand.
For many, but not all of the listed “alcohol related
conditions included in the study”, there is a body of literature
supporting benefits with moderate intakes. These benefits risk change to harm
after an intake threshold is exceeded. Others conditions have no discernible
alcohol benefit at moderate intakes and in others there are marginal, difficult
to quantify adverse effect of low to moderate intakes. There are thus two
populations which need separate analysis.
A provocative conclusion of this paper is “there are
no health benefits before middle age”. In fact, it is likely that the
demonstrated benefits may occur earlier in life. Most degenerative diseases such
as coronary artery disease become manifest in middle or old age after a long
incubation. The initiation of deterioration is due to multiple factors including
adverse life styles. Surrogate markers may be present long before clinical
disease is evident and provide an opportunity for an early insight into the
evolution of risk factors and their relationship to alcohol intake.
There is a substantial literature directed to the effects of
alcohol on disease risk markers. Most, but not all, suggest moderate alcohol
intake is beneficial. I list a small sample3–6
A number of these studies include some younger adults but few focus
specifically on moderate young adult drinkers.
Younger drinkers are usually the research target of studies
of binge drinking and overall high alcohol
intake.7 High alcohol intakes, especially if
ingested rapidly (binging), is hazardous with risk of serious adverse social and
long-term health consequences. The intake threshold for adverse events is
generally considered to be about 60 grams of alcohol in 1 day, but for some
people it may be lower. There are two results of inappropriate alcohol use;
unsafe social behaviours (particularly in the young), and medical problems with
loss of life at an older age. The benefits of moderate drink apply to all age
groups.
I believe that the base alcohol guideline recommended by the
Nutrition Taskforce is validated. The guideline would be strengthened by the
addition of “preferably with food”, a concept supported by published
evidence8,9 and offers a pleasurable approach
to foster a culture of moderate drinking for those who choose to drink
alcohol.
