Health authorities in developed nations around the world are
making an increasingly determined effort to reduce the burgeoning
waistlines among their citizenry. The U.S. Department of
Agriculture (USDA) is rethinking its famous food pyramid (as it
does every five years), preparing to release new guidelines in
2005. Globally, the World Health Organization (WHO) is focused on
reducing worldwide obesity by encouraging countries to enact public
policies and clinical guidelines promoting healthy diets and
increased exercise.
Recent Gallup polling in the United States, Canada, and Great
Britain* suggests that adults in these three countries are neither
overly enthusiastic nor highly critical about the healthiness of
their diets. Only a quarter (24%) of Americans and about a third
each of Canadians (32%) and Britons (30%) feel that their diets are
"very healthy." Roughly 60% of residents in each country
characterize their diets as "somewhat healthy." Fifteen percent of
U.S. adults see their diets as either "not too healthy" or "not
healthy at all," compared with 11% of Britons and just 6% of
Canadians.

The low-carb dieting theory originated in the United States,
when Dr. Robert Atkins introduced his "Diet Revolution" in 1972.
But this strategy has gained immense popularity in the last few
years, and low-carb products are now offered throughout the world,
including Canada and Great Britain. The recent Gallup Polls also
asked adults in each of the three countries which diet they think
is more beneficial from a health perspective -- a low-carb diet or
a low-fat diet. Significant majorities of people in each country
feel that low-fat diets are more beneficial, although Americans are
slightly more likely than Britons to feel that low-carb diets are
the healthier option.

The USDA recommends that adults consume a varied diet that
includes plenty of fruits and vegetables, whole grain cereals, lean
meats, and low-fat dairy products, while avoiding high-sugar,
high-fat, and high-salt foods.
Which foods do American, Canadian, and British adults actively
include in their diets? All three nationalities report
including many traditionally healthful options -- such as fruits,
vegetables, fish, and poultry -- in their diets, but carbohydrates
fall relatively low on the list of actively included foods,
especially in the United States. Only 33% of Americans, 43% of
Canadians, and 56% of Britons say they actively include
carbohydrates in their diets. Canadians are substantially more
likely than either Britons or Americans to say they actively
include dairy products.

Bottom Line
A recent WHO report found that more than 1 billion people
worldwide are overweight and more than 300 million are clinically
obese. Forty-four percent of Americans, 39% of Canadians, and 36%
of Britons see themselves as either somewhat or very
overweight.
The WHO has examined the sources of the alarming obesity
epidemic and has concluded that several factors -- including
declining physical activity in urban societies and increased use of
automated travel and technology -- are at work. But another obvious
factor is deteriorating diet. In all three countries that Gallup
measured, 15% or less of adults classify their diets as unhealthy,
but more than a third in each country feel that they are
overweight. Adults in these countries, especially those struggling
with weight, may need to re-evaluate what they consider "healthy"
eating habits.
*Results in the United States are based on telephone
interviews with 1,022 national adults, aged 18 and older, conducted
Sept. 13-15, 2004; 1,005 national adults, aged 18 and older,
conducted July 8-11, 2004; 2,250 national adults, aged 18 and
older, conducted June 9-30, 2004; and 1,000 national adults, aged
18 and older, conducted May 2-4, 2004. For results based on
the total sample of national adults, one can say with 95%
confidence that the maximum margin of sampling error is ±3
percentage points. The survey was conducted by Gallup
USA.
Results in Canada are based on telephone interviews with
1,005 national adults, aged 18 and older, conducted Aug. 30-Sept.
6, 2004. For results based on the total sample of national adults,
one can say with 95% confidence that the maximum margin of sampling
error is ±3 percentage points. The survey was conducted by
Gallup Canada.
Results in Great Britain are based on telephone interviews
with 1,009 national adults, aged 18 and older, conducted Aug.
25-Sept. 7, 2004. For results based on the total sample of national
adults, one can say with 95% confidence that the maximum margin of
sampling error is ±5 percentage points. The survey was
conducted by Gallup UK.
In addition to sampling error, question wording and practical
difficulties in conducting surveys can introduce error or bias into
the findings of public opinion polls.
