1.Introduction As part of cultural traditions and well balanced lifestyles wine,
beer and spirits consumption has been a common staple in diets
around the world. In acknowledgement of such practices, groups
of nutrition experts have included the moderate consumption of
alcohol as an optional component of various dietary guidelines
and food guides such as: the Mediterranean, Asian, Latin American and Vegetarian Pyramids.
Here we outline the key scientifically based nutrition messages in
these pyramids.
The outlined alcohol-inclusive dietary pyramids are part of an
effort by Oldways Preservation & Exchange Trust, a non- profit
education group that is dedicated to preserving traditional eating
patterns with the goal to improve consumer knowledge and diets
around the world. Oldways has prepared these concepts with prominent
nutrition, medical, biomedical and communication experts from
leading institutions such as the WHO Regional Office for Europe
and the Harvard School of Public Health.
Cardiovascular disease and cancer are leading causes of death
in developed nations around the world, predominantly being associated
with diets high in animal fats. With that emerging scientific
consensus, the Oldways pyramids all emphasize fruits, vegetables,
cereals and pulses with little meat (animal fats) consumption.
These nutrition concepts also include wine, beer and spirits,
which have shown to contribute to lower heart disease rates and
improve longevity.
Accumulating scientific evidence suggests that moderate consumption
of wine, beer and spirits does not pose a health risk to the vast
majority of consumers who choose to drink in moderation. AIMs
recommendations also emphasise that adults should enjoy alcohol
beverages in a sensible manner, preferably around mealtimes or
other responsible social settings. Moderation is the key to a
healthy diet and lifestyle, and this is reflected in several traditional
nutrition concepts.
Consumers should follow moderation guidelines such as those in
the Dietary Guidelines for Americans which define moderation as
up to two drinks (12g) a day for men and up to one drink a day
for women; further, consumers should avoid alcohol during pregnancy
or whenever it would put the individual or others at risk. To

Alcohol-Inclusive Nutrition Concepts:The The Eatwise concept
The latest "Eat Wise" Pyramid, including "wine, beer and spirits
in moderation" as part of a daily beverage recommendation was
released at Januarys 2003 Mediterranean Diet Conference sponsored
by Harvard School of Public Health and Oldways Preservation &
Exchange Trust. This new pyramid is modelled on the original Mediterranean
Diet Pyramid, which initially only recommended wine in moderation,
reflecting the cultural preference of the Mediterranean region.
"This Eat Wise Pyramid is a visual guide to healthy living the
Eat Wise way," the accompanying text states. "It shows the partnership
of a balanced diet, plenty of water, regular physical activity,
and alcohol in moderation that wise eaters know strengthen all
their bodies functions." An expert conference discussion emphasized
the potential benefits for all three beverages. Eat Wise Meal
Ideas, shopping tips and recipes are outlined in a special eating
guide that can be ordered via the Oldways website.
The Mediterranean Diet Concept
Long known for its healthy lifestyles and the longevity of its
people, the Mediterranean region is also home of some of the most
palatable and healthy foods on earth. Traditionally, wine has
been included as an integral part of its meals, and cross-cultural
studies have reported significantly lower risk of heart disease
in Mediterranean regions where alcohol is a daily staple of a
healthy diet and lifestyle. As the preferred beverage in this
region, wine is specified as an option on "The Traditional Healthy
Mediterranean Diet Pyramid," developed by Oldways in cooperation
with scientists from the WHO in Europe and from the Harvard School
of Public Health. This traditional diet is based on grains, including
rice, polenta, bulgur and pasta, as well as legumes and vegetables.
It also includes fruits, cheeses, yogurt and nuts along with the
optional choice of alcohol in moderation. Olive oil is given its
own category as a major source of mono unsaturated fat, reflecting
its important prominence in the regions healthy cuisine. Daily
physical activity, a factor contributing to health in the Mediterranean
region and elsewhere, is also included on this and all Oldways
pyramids.
The Asian Diet Concept
As Asian cuisine continues to become popular in diverse regions
of the world, characteristics of Asian diets will continue to
gain importance. In Japan and China, studies have found rates
for heart disease and many types of cancer to be lower than those
in the United States and the rest of the world. The centuries-old
traditional Asian diet of rice, noodles, vegetables and fish is
believed to be a significant contributor to the documented lower
rates for chronic disease in these populations. The "Traditional
healthy Asian Diet Pyramid," developed in cooperation with scientists
at Cornell University and the Harvard School of Public Health,
incorporates these dietary patterns into the pyramid format. Sake,
wine, beer, and other beverages with alcohol in moderation, as
well as tea, are included as part of the pyramid because studies
have shown that their consumption may play an role in reducing
heart disease risk and overall mortality.
"The The Latin American Concept
The Traditional Healthy Latin American Diet Pyramid," released
in 1996, is based on the traditional foods of Latin America. Unlike
the Americanized versions that tend to be high in salt and fat,
this pyramid presents many healthy eating options. It emphasizes
daily consumption of beans, grains, tubers and nuts along with
fruits and vegetablesstaples in most Latin American and Caribbean
regions. Daily physical activity is integrated into the pyramid
structure in recognition of the scientific consensus on the importance
of exercise in maintaining good health. Alcohol in moderation
with meals is included as an option, and, as with other cultural
pyramids, meats, sweets and eggs are at the very top of the pyramid,
in the "occasionally" category to advocate a healthy and balanced lifestyle that can reduce the
risk for several common diseases.
The Vegetarian Diet Concept
The unique "Vegetarian Diet Pyramid," released by Oldways at the
end of 1997, serves as a model for healthy eating with meals built
around vegetables, fruits, whole grains and legumes. The pyramid
also emphasizes daily physical activity, water consumption and
the option of "wine, beer and other alcohol" in moderation. The
importance of this dietary concept, according to Oldways, is that
it reflects the growing number of vegetarians and acknowledges
the nutritional and health benefits of this type of diet. For
example, the Dietary Guidelines for Americans have acknowledged
such a diet as able to meet Recommended Dietary Allowances (RDA)
for nutrients. While some vegetarians are prohibited from consuming
meat and alcohol for religious reasons, all alcohol beverages
are included as a choice because of the potential risk reduction
for heart disease and its cultural role as an accompaniment to
vegetarian eating.
The Scientific Evidence
The nutritional and medical significance of the traditional Oldways
Dietary Pyramids was featured in "Medical News Perspectives" of
the Journal of the American Medical Association in 2000. The author
highlighted the importance of well-balanced and nutritious diets
as a potential disease prevention measure that could be increasingly
conveyed by physicians and healthcare providers to their patients. More recently, Greek and US scientists investigated the health
effects of adherence to a Mediterranean Diet reported in the New England Journal of Medicine in 2003: "Greater adherence to the traditional Mediterranean diet
is associated with a significant reduction in total mortality."
Coinciding with these acknow-ledgements, there is now a developing
scientific consensus that, for many individuals, moderate wine,
beer and spirits consumption is associated with a reduced risk
of coronary heart disease and increased life expectancy which
lead to the above featured alcohol-inclusive nutrition concepts.
In 1997,Sir Richard Doll, Emeritis Professor of Medicine at Oxford,outlined
in the British Medical Journal "massive" evidence for the potential beneficial effect of alcohol
in a review of the clinical data on alcohol and mortality. He
concluded that "the consumption of small and moderate amounts
of alcohol" leads to a one-third-risk reduction for vascular disease.
He also acknowledged a reduction in total mortality in middle-aged
and elderly men and women when they consumed wine, beer or spirits.
More recently, world-renowned expert Dr. Arthur Klatsky from the
US outlined the overwhelming scientific evidence in Scientific American. Dr. Klatsky has published many research studies on alcohol and
health in leading scientific journals from the large-scale Kaiser
Permanente cohort and in the recent article he wrote with respect
to the most appropriate advice to the public, "On one hand, mild
to moderate drinking seems better for heart health than abstinence
for select people. On the other hand, heavy drinking is clearly
dangerous." Merely recommending abstinence is inappropriate health
advice to people such as established light drinkers at high risk
of CHD and at low risk of alcohol-related problemswhich describes
a large proportion of the population." Dr Klatsky along with other
experts from around the world has advocated that health professionals
make case-by-case evaluations based on individual and family histories.
They also emphasize that the public should be entrusted with all
the information on use versus misuse of alcohol so that they can
make informed decisions themselves.
Authoritative findings from cohorts internationally, lead research
experts to feature the option of moderation in each traditional
Oldways Dietary Pyramid. Many peer-reviewed studies from Europe,
Asia, Australia and the US have revealed potential benefits for
moderately drinking adults in multi-ethnic populations. These studies find that moderate drinkers, especially consumers
of 1-2 drinks (12g) daily, may lower their risk of heart disease
significantly. Studies reporting certain health advantages for
moderate drinkers include the Lyon Heart Study, the Copenhagen
City Heart Study, the Australian Dubbo Study and the European
Seven Country Study.
The Oldways experts, working with the Harvard School of Public
Health, specifically considered findings from the ongoing Physicians
Health Study and the Nurses Health Study. Analyzing data from
84,000 women in the Nurses Health Study the effect of a combination
of diet and lifestyle factors were assessed on the risk of CHD,
Dr Meir Stampfer et al concluded," In this population of middle-aged
women, those who did not smoke cigarettes, were not overweight,
maintained a healthful diet described above, exercised moderately
or vigorously for half an hour a day, and consumed alcohol moderately
had an incidence of coronary events that was more than 80% lower
than that in the rest of the population." At the same time, based
on a prospective study of more than 89,000 men as part of the
Physicians Health Study, Harvard researcher Dr Michael Gaziano
et al concluded," In summary, this study reveals the complex effect
of alcohol consumption on various chronic diseases as reflected
in the overall U-shaped relationship between light-to-moderate
alcohol consumption and total mortality in men."The earlier results
from the US governments funded National Health and Nutrition
Examination Survey (NHANES) were also considered, which found
that the risk for CHD is reduced for both men and women who drink
moderately. Published in 1997 in the American Journal of Epidemiology it stated:, "This analysis confirmed previous research showing
that abstainers are at a greater risk for CHD than are most non
abstainers and that a significant protective effect may be demonstrated
with small amounts of alcohol." Along those lines, research published
in The New England Journal of Medicine from American Cancer Society experts concluded, "In this middle-aged
and elderly population, moderate alcohol consumption slightly
reduced overall mortality."
At the same time, there are continuing concerns about alcohol
consumption and breast cancer and women are recommended not to
drink when pregnant , in line with governmental and public health
positions in the US. Authoritative statements from public health
groups such as the American Heart Association, the National Stroke
Association and the American Dietetic Association acknowledge
the scientific evidence pointing to potential benefits of moderation
with respect to coronary heart disease and emphasize, "If you
choose to drink, do so in moderation." A balanced summary position
is reflected in the 1999 JAMA Patient Page on "Benefits and dangers
of alcohol", which defines Moderate drinking as 1 or 2 drinks
(12g) a day for men and 1 drink a day for women and those older
than 65. These messages are embodied in governmental positions
in the US, UK, Australia and Canada.
The Oldways alcohol messages as reflected in the pyramids are,
however, especially notable in that they emphasize consumption
with or around mealtime, as research has shown that these and
related cultural norms facilitate responsible drinking habits,
may slow alcohol absorption and may counter potential harmful
effects of fatty foods. For example, Dr. David Hanson, author of Preventing Alcohol Abuse:
Alcohol, Culture, and Control, explains, "The cross-cultural evidence
indicates that drinking abuse will be low in any group in which
drinking customs, values and sanctions are clear
. and characterized
by prescriptions for moderate drinking and proscriptions against
immoderate drinking." Furthermore, several biochemical studies
indicate that in addition to slowing down the absorption process,
which keeps blood alcohol levels lower, moderate consumption during
or around mealtime may have favourable effects on lipid profiles
and atherogenesis. One 1998 study published in the American Journal
of Clinical Nutrition, suggested "ethanol may reduce cardiovascular
risk by modulating vascular muscle growth during the postprandial
period." Research continues, but it appears clear that healthy
dietary patterns are inversely related with low rates of chronic
diseases. This has been specifically confirmed in the ongoing
Seven Country Study which reported in 1999 that animal-food groups
were directly correlated with CHD mortality while vegetable-food
groups, as well as fish and alcohol were inversely correlated.
In summary, in line with the developing scientific consensus,
public health and governmental positions, the Oldways pyramids
stress moderation and underscore the importance of an overall
healthy meal and lifestyle.Consumption is not recommended for
non-drinkers or those who may have any health contraindications
and consumers are always advised to consult with their healthcare
providers.
