Red wine, we know about. Now for the good news on
benefits of beer
"There are more old drunks than there are old doctors," country star Willie Nelson once said.
Although no doctor himself,
Nelson may have been on to something. Long associated in many minds with a Homer Simpson
sagging belly and lifestyle, beer is gaining status as a drink with definite health benefits,
at least when consumed in moderation.
For some time now, we've been hearing that a glass of red wine every day may help avoid
heart disease. For that glad discovery, we owe a debt to the French.
Now comes further enlightenment about beer, and wouldn't you know it: Australians are
helping to amass the evidence.
Protection against heart disease?
For starters, beer seems to offer protection against cardiovascular disease including
heart attack and stroke. According to Foster's, Australia's global brewery, three glasses
of beer a day (30 grams of alcohol) may reduce heart attack risk by a whopping 25 per cent.
By this logic, total abstinence could be a public health disaster. In the unlikely event that
all Americans suddenly hopped on the wagon, the shocking result would be 81,000 deaths from
coronary heart disease, according to an editorial in the Journal of the American Medical
Association. Fortunately, the chances of such a catastrophe are slim. In Canada alone,
brewers chalk up annual sales of over $10 billion.
It's not the beer, it's the booze
Actually, it's not the beer but the alcohol content that's good for the heart, according
to Dr. Kenneth Mukamai and Dr. Eric Rimm, two Harvard professors who made an exhaustive
review of the scientific literature on drinking and cardiovascular problems. After looking
over 40 studies, they concluded that "consumption of two standard drinks daily
(for beer, 12 fluid ounces) would be expected to lower a person's risk of coronary
heart disease by nearly 25 per cent."
Alcohol in moderation is apparently good for the head as well as the heart. Modest
consumption seems to lower the risk of stroke, the brain equivalent of a heart attack,
perhaps by as much as 50 per cent.
"There's good evidence that beer and alcohol in general is associated with lower
mortality," says Dr. Meldon Kahan, family physician and medical director of the Addiction
Medicine Service at St Joseph's Health Centre in Toronto.
Beer seems to reduce risk of heart disease
"People who drink moderately are less likely to die, primarily from heart disease. That's
because alcohol inhibits the aggregation of platelets, the clumping together of the little
sticky things in blood that stop us from bleeding but can also lead to heart attacks. Also,
it improves the lipid profile by elevating high-density cholesterol, the so-called 'good
cholesterol.' There's very good evidence for that."
Unlikely as it may seem, moderate drinking may also be associated with lower risk of stomach
ulcers. According to the British Medical Journal, alcohol seems to protect the stomach
against H pylori bacteria, the germs associated with gastrointestinal ulcers.
Other studies show moderate alcohol consumption can lower the risk of adult onset (type 2)
diabetes and gall stones. In women, moderate drinking also seems to help maintain bone
density and reduce the chances of rheumatoid arthritis.

The original barley sandwich
On top of its medical benefits, it has nutritional advantages. A litre of beer contains
about 20 per cent of the recommended daily intake of fibre, as well as a heaping dose of
B vitamins and antioxidants. "Beer comes from grain and that's a major source of B vitamins," says Lois Ferguson, registered dietitian and author of the Canadian bestseller Eating For Energy And Ecstasy. "With beer you get a whole range of B vitamins, including niacin, riboflavin, B6 and folate."
Contrary to popular belief, beer is relatively low in calories, being 97 per cent water.
"A 12 ounce bottle of beer contains 151 calories," says Ferguson. "Compare that to a soft
drink with about 150 to 170 calories, or an 8- ounce coke with a shot of rye, which packs
about 300 calories."
Glass for glass, beer contains less calories than even apple juice or even milk. Why, then,
are bulging paunches known the world over as "beer bellies"?
Not many of us are tempted towards multiple refills of milk or fruit juice, for one thing.
If we were, there'd be fewer saloons and more milk bars.
And as a European brewers association points out, beer bellies may be the byproduct of a
generally unhealthy lifestyle as much as a fondness for barley sandwiches.
Despite all its benefits, beer isn't exactly the elixir of a long life. "It's true that
moderate consumption of beer provides some important health benefits," says Howard Collins,
executive vice president of the Brewers Association of Canada.
Not exactly a health product
"It's taken science decades to catch up to what our grandparents seemed to know intuitively
about this. On the other hand, we'd never take the view that beer is a health product. It's
an alcoholic refreshment beverage."
And like any other alcoholic beverage, beer has a dark side. While scientists agree moderate
alcohol consumption has some upsides, they don't know what the "ideal" intake of alcohol
actually is.
"Probably most of the benefits of alcohol can be obtained from one drink every two days,
but it may be higher than that," says Kahan. "Current recommendations in Canada are no more
than 14 drinks a week for men and nine for women.
"Moderation is the key and even then, people have to be aware there are many exceptions to
the general rule that beer is healthy. For one thing, it hasn't been shown to be healthy for
young people. The more young people drink, on average, the more likely they are to die from
accidents, violence or suicide. Pregnant women shouldn't drink. Nor should people on certain
types of medication."
Possible links to some cancers
Cancer is also a concern. Some evidence suggests even moderate amounts of alcohol may elevate
the risk of breast cancer. Several studies have shown a link, although the evidence isn't
clear enough for doctors to advise women to abstain. Cancers of the mouth, esophagus and
liver are also linked to excessive drinking.
"People definitely shouldn't increase their beer consumption just for health reasons," says
Kahan. "Nor should they start drinking because of the supposed health benefit. Exercise and
a healthy lifestyle will cut risk of heart disease just as effectively.
"On the other hand, if people are drinking within safe limits, and if it's not having any
adverse effects, then they shouldn't worry about it. The great majority of people don't have
problems with drinking. For them, beer is fine. They should just enjoy it."
Ferguson agrees wholeheartedly: "People need to be educated so they know beer is a fine
choice as part of a healthy diet and a lifestyle which includes exercise. Within those
parameters, enjoy beer. Pay attention to the taste and enjoy the subtleties of flavor. It's
fascinating to taste different types of beer and train yourself to recognize them.
"Leonardo Da Vinci said 'great love is born of great knowledge of the thing loved.' That
applies to beer. The more educated you are about the intricacies of the flavour, the more
pleasure you get from it.
"And why not? Food and beverages are for our pleasure, as long as we're educated and in
control."
