Cocoa Has A Rich Content of  Polyphenol Antioxidants and  Middle-Aged and Elderly Swedish  Women Who Regularly Ate a Small  Amount of Chocolate Had Lower   Risks of Heart Failure Risks,

In A Study reported in Circulation: Heart Failure, A Journal of the American Heart Association.

The nine-year study, conducted among 31,823 middle-aged and elderly Swedish women, looked at the relationship of the amount of high-quality chocolate the women ate, compared to their risk for heart failure. The quality of chocolate consumed by the women had a higher density cocoa content (like dark chocolate by American standards.) In this study, researchers found:

· Women who ate an average of one to two servings of the high- quality chocolate per week had a 32 percent lower risk of
developing heart failure.· Those who had one to three servings per month had a 26   percent lower risk. · Those who consumed at least one serving daily or more didn’t  appear to benefit from a protective effect against heart failure.

The lack of a protective effect among women eating chocolate every day is probably due to the additional calories gained from
eating chocolate instead of more nutritious foods, explained the researchers conducting the study.

“You can’t ignore that chocolate is a relatively calorie-dense food and large amounts of habitual consumption is going to raise your risks for weight gain,” said researchers from the Cardiovascular Epidemiology Research Unit at Harvard Medical School’s Beth Israel Deaconess Medical Center in Boston. “But if you’re going to have a treat, dark chocolate is probably a good choice, as long as it’s in moderation.”

High concentration of compounds called “flavonoids” (Polyphenol Antioxidants) naturally present in chocolate may lower blood
pressure, among other benefits, according to mostly short-term studies. However, this is the first study to show long-term outcomes related specifically to heart failure, which can result from ongoing untreated high blood pressure.

In the observational study, researchers analyzed self-reported food-frequency questionnaire responses from participants 48-
to-83-years-old in the Swedish Mammography Cohort. Combining the results with data from national Swedish hospitalization and death registries between 1998 through 2006, the researchers used multiple forms of statistical modeling to reach their
conclusions on heart failure and chocolate consumption.

It’s important to note the differences in chocolate quality which affect the study’s implications. Higher cocoa content is associated with greater heart benefits. In Sweden for example, even milk chocolate has a higher cocoa concentration than dark chocolate sold in the United States.

Although 90 percent of all chocolate eaten across Sweden during the study period was milk chocolate, it contained about 30 percent cocoa solids. U.S. standards only require 15 percent cocoa solids to qualify as dark chocolate. Thus, by comparison, American chocolate may have fewer heart benefits and more calories and fat per equivalent amounts of cocoa content compared to the chocolate eaten by the Swedish women in the study.

Also, the average serving size for Swedish women in the study ranged from 19 grams among those 62 and older, to 30 grams
among those 61 and younger. In contrast, the standard American portion size is 20 grams.

Researchers stressed “This is not an ‘eat all you want’ take-home message, rather it’s that eating a little dark chocolate can be
healthful, as long as other adverse behaviors do not occur, such as weight gain or excessive intake of non-nutrient dense ’empty’ calories.”

Heart failure occurs among about 1 percent of Americans over age 65. A condition in which the heart can’t pump enough blood to the rest of the body, heart failure rates are increasing as our aging population grows.

“Anything that helps to decrease heart failure is an important issue worth examining,” they concluded.
