The vegetarian and vegan diet and lifestyle have been on the upsurge,
resulting in books and a slew of articles in major news outlets. Leading
the list is the December 15, 2006 report
in the prestigious British Medical Journal about a study of some 8,200
men and women with a startling conclusion: Kids with the highest IQs
were more likely to become vegetarians as adults, also possibly lowering
their risk of cardiovascular disease. “Brighter people tend to have
healthier dietary habits,” said the researcher and author Catherine
Gale, PhD.
Dr. Gales' team gathered data on a group of 30-year olds whose IQs had
been tested when they were 10-years old. According to Dr. Gale,
“children who scored higher on IQ tests at age 10 were more likely than
those who got lower scores to report that they were vegetarian at age
30.” [Let's not say, “We could have told you so.]
Also recently, the New York Times ran several vegan-friendly articles.
In the January 11, 2007 article in the Style section called “Uncruel
Beauty,” they write extensively about vegan
fashions, also including favorable mentions of "cruelty-free" diets and
stores like “Whole Foods,” and eco-minded labels like Novacas [no cows].
A week later, on January 24th, the
Times ran a long and flattering article with vegan recipes in the Dining
and Wine Section, called “Strict Vegan Ethics, Frosted With Hedonism.”
In it, they interview vegan chef, Isa
Chandra Mowkowitz.
Also in January 2007, the venerable New Yorker and trendy Internet
magazine Salon wrote long and extensive reviews of Tristram Stuart’s
recent book, “The Bloodless Revolution: A
Cultural History of Vegetarianism from 1600 to Modern Times.” The New
Yorker reviewer wrote, “Stuart is of the opinion that vegetarians have
long had the best intellectual
arguments.” And, there’s much more. In my regular column in the trade
publication, Nurse Practitioners Word News, I wrote about several recent
medical reports of health benefits from a plant-based diet. Among these
was a study of middle-aged vegetarians on a diet relatively low in
protein and calories.
The researchers reported in December 2006 in the American Journal of
Clinical Nutrition that the low-protein group had lower blood levels of
several hormones and other substances tied to certain cancers than
people eating the typical meat-based American diet. [Here’s your answer
to the proverbial, "Where do you get your protein?]
In another cancer study in the November 2006 issue of American Journal
of Clinical Nutrition, Washington University researchers reported that
those staples of the vegetarian diet, onions and garlic, have a lower
cancer risk. The researchers analyzed eight Swiss and Italian studies
and concluded that older people with the highest onion and garlic
intakes had the lowest risks of certain cancers [particularly colon,
ovarian and throat cancer].
Other research also found that garlic and tomatoes may have
“synergistic” cancer-fighting effects when taken together. Vegetables
also fared well against a common eye disease that can lead to blindness
called age-related macular degeneration. A study in the Archives of
Ophthalmology (August 2006) looked at 1,787 women and found that this
disease may be prevented with a diet high in lutein plus zeaxanthin,
which are plant pigments [called carotenoids] that are found in leafy
green vegetables, corn, squash, broccoli, and peas.
While there have been many studies showing positive health benefits from
vegetarian foods, a great many studies show an opposite, negative
effect, from animal foods. Most recently, researchers at Harvard Medical
School found that in a long-running study of 90,659 women, those women
who were premenopausal and ate more red meat had a higher risk of
getting hormone receptor-positive breast cancers. The impetus for all of
these and other studies and for the growing press coverage is
undoubtedly influenced by the fact that vegetarianism and veganism
appears to be inching up statistically in the U.S.
The 2006 Statistical Abstract of the United States found that during the
20 years between 1980 and 2003, the per capita consumption of red meat
fell from 126.4 pounds to 111.9 pounds. In contrast, fresh vegetable
consumption rose from 338.4 to 416.6 pounds and fresh fruits from 105.1
to 126.7 pounds. [Certain disease rates are also down, and statisticians
have yet to make the connections.]
How many vegetarians are there? Polling data differ. In a 1994 Roper
Poll of 1,978 men and women 18 years and older, 6 % said they never eat
meat (compared with 75% who said they eat everything). An earlier Gallup
Poll in 1991 conducted for the National Restaurant Association found
that about 20 % of the population looks for a restaurant with vegetarian
items when they eat out. Compare this to a 2000 report by the market
research firm Opinion Research for the leading producer of refrigerated
foods called Lightlife, which conducted a random sampling of 1,000
American adults. They found that 44 % of Americans now eat vegetarian
foods as part of a daily diet “because they know how healthy vegetarian
food is for them.”
Among teens and college students. The market research series “The U.S.
Market for Wellness Foods and Beverages” published in August 2003 by
Packaged Facts, claimed that a growing percentage of teens are calling
themselves vegetarian or are open to it. Among college students, a 2004
survey conducted by a company specializing in food services for schools
found that nearly 25% of students said that finding vegan meals on
campus was important to them. Compare all of the above to a 1977 U.S.
Department of Agriculture Nationwide Food Consumption Survey of 37,135
people in which only 1.2 % answered "yes" to the question “Are you a
vegetarian?” The Vegetarian Resource Group (www.vrg.org), in the
previously mentioned Jan. 11th New York Times article claims there are
an estimated 4.8 million vegetarians in the U.S., one-third to one-half
of whom are vegan. “That number has nearly doubled since 1997,” they
report.
