Here's a treat for you and all the rest of us chocolate lovers.
A Heart-Healthy Affirmation for the World's Chocoholics
By Jon Marino Times Staff Writer
WASHINGTON — Rather than using those dark delights to win the heart of another on
Valentine's Day (news - web sites), chocolate lovers may want to take that beribboned
box home to improve their own.
Experts gathered Tuesday at the National Academy of Sciences (news - web sites) to
discuss the cocoa-based confection, which contains chemicals, called flavanols, shown
to improve blood flow and reduce blood pressure.
The 2004 Cocoa Symposium — sponsored by UC Davis, UC Santa Cruz, the National
Institutes of Health (news - web sites), the Department of Health and Human Services (
news - web sites) and Mars Inc., the candy manufacturer — also examined ways to prevent
disease in cacao plants, which produce the seeds that make chocolate and cocoa, and to
encourage the cultivation of the plants as a solution for depleting tropical
vegetation.
The potential health effects of flavanols were discovered two years ago, when studies
of blood vessel function compared individuals who ate Dove dark chocolate — which has
high levels of the chemicals — to those who ate chocolate with a lower amount of
flavanols.
Mars, Dove's manufacturer, used that research as the basis for CocoaVia, a low-fat,
flavanol-rich snack that is being test-marketed and is currently only available online.
An 80-calorie bar, which contains 100 milligrams of flavanols, is the first step toward
creating a truly healthful chocolate, said Harold Schmitz, director of science at Mars.
While recognizing the potential health benefits of chocolate, scientists also have
noted that most commercially produced chocolate contains high levels of fats and sugars
— which could negate the beneficial effects.
"Most of the chocolate currently available is delightful and delicious, but it's not a
health food," said Norman Hollenberg, a professor of medicine at Harvard Medical School
(news - web sites). "But it's imminent, it's coming," he said of flavanol-enriched
chocolates.
Ten years of research, dozens of reviews in scientific journals and millions of dollars
— no precise amount was given — have shown that through proper growing, fermenting,
roasting and processing, healthful chocolate can be distilled, Schmitz said. Because
Mars is privately held, he said, it can do research that investors in a publicly traded
firm might consider wasteful. Flavanols also are found in apples and other plant-based
products such as wine and green tea.
The scientists also examined diseases in cacao plants, which cost the industry up to $1
billion annually. Molecular modification, said Raymond J. Schnell, supervisory research
geneticist at the U.S. Department of Agriculture (news - web sites), has the potential
to make cocoa plants more resistant to disease; naturally occurring fungi could also
protect.
Additionally, research conducted through a public/private partnership including UC
Davis, Harvard University and the World Bank (news - web sites) has shown that family
farmers in tropical regions can benefit from growing cacao while replenishing rain
forests. Central and South American nations have most of the world's cacao production,
but African and Southeast Asian countries contribute as well. "The goal is to get out
of poverty, and to do so in a way that is environmentally benign," said the World
Bank's James Bond.
