Study Reveals Differing Amounts of Naturally Occurring Flavanols in Chocolate and Cocoa Powder
Monday April 4, 1:00 pm ET
- Natural Cocoa Powders, Unsweetened Baking Chocolates Rank Highest in Findings
SAN DIEGO, April 4 /PRNewswire/ -- A new Agricultural Research Service (ARS) study evaluating total amounts of flavanols and antioxidant capacity in cocoa and chocolate shows that antioxidants are found in a range of chocolate products -- but more so in those with a higher cocoa content.
Scientists from ARS, the chief scientific research agency of the U.S. Department of Agriculture, presented the findings today at Experimental Biology 2005, an international scientific conference held in San Diego. The study was funded in part by the American Cocoa Research Institute (ACRI), the research arm of the Chocolate Manufacturers Association (CMA).
In this study, the scientists found that the chocolates ranked in antioxidant capacity from highest amount to lowest were natural cocoa powder, unsweetened baking chocolate, alkalinized or "Dutch" cocoa powder, dark chocolates, semi sweet chocolate baking chips, and milk chocolates.
The results were based on chocolate samples from commercially available products under nine brands, as well as reference standards provided by the United States National Institute of Standards and Technology (NIST). ARS scientists, located at the Beltsville Human Nutrition Center, Brunswick Labs, and the Arkansas Children's Nutrition Center analyzed these samples in a blind test for flavanol content and antioxidant capacity.
Flavanols are the main flavonoids found in cocoa and chocolate. Research over the past decade has identified flavonoids as showing diverse beneficial physiological and antioxidant effects. Flavonoids are compounds also found in fruits, vegetables, and certain beverages such as tea, red wine, and grape juice.
"These results indicate that products derived from cocoa beans, which come from the cacao tree, also contain flavanols, with the highest amount in natural cocoa powders," explains Dr. Leah Porter, vice president of scientific affairs for the CMA. "This study also demonstrates that chocolate products containing higher amounts of cocoa have higher antioxidant capacity."
"The findings provide further scientific evidence that cocoa is a rich source of antioxidant activity, such as other antioxidant-rich foods including red wine, cranberries and blueberries," said CMA President Lynn Bragg. "This research increases knowledge of a wonderfully familiar food, and comes at a time when we are finding new ways to use cocoa and chocolate (e.g., as an ingredient and flavor) in a variety of foods. There is a chocolate for everyone and it can be enjoyed -- in moderate portions -- as part of a balanced diet."
According to Chef Carole Bloom, a chocolate expert and award-winning author of Chocolate Lover's Cookbook for Dummies, All About Chocolate, and Truffles, Candies, and Confections, there are many ways to incorporate cocoa and chocolate into a diet in a way that enhances the flavor of healthy foods. Some suggestions include:
-- Sprinkle cocoa powder on popcorn, warm and cold coffee drinks, low fat
or non fat plain yogurt mixed with fresh fruit, and baked pears, apples
or other fruit
-- Mix small bite-size pieces of dark chocolate in with a homemade trail
mix of nuts and dried fruits
-- Add chocolate shavings or cocoa nibs to fresh fruit cups, salad greens,
or cold cereals such as granola or warm cereals such as oatmeal or
cream of wheat
-- Dip fresh or dried fruits such as strawberries, bananas or dried
apricots into chocolate
-- Add chocolate chips into easy to bake vegetable breads or cakes such as
banana bread, pumpkin bread, or carrot cake
-- Incorporate into sauces such as Mexican mole and use with chicken,
fish, turkey or pork
Bragg summarized, "Chocolate has been and will continue to be an important research area, and we are constantly learning more about its many unique properties. The CMA is supportive of industry research that increases the understanding of the dietary contribution and role of flavanols in a healthy lifestyle."
About the Chocolate Manufacturers Association
The Chocolate Manufacturers Association (CMA) has served as the premiere trade group for manufacturers and distributors of cocoa and chocolate products in the United States since 1923. The association was founded to fund and administer research, promote chocolate to the general public and serve as an advocate of the industry before Congress and government agencies. CMA's mission is to serve as the voice of the American chocolate industry and through research, education and public information, works to ensure a continued supply of cocoa and consumption of high value and quality chocolate products for the American people. CMA members represent over 90% of the chocolate processed in the United States. For more information on CMA visit
