Feb. 27, 2006 -- Amber ability advice barrier claret burden and lower afterlife risk, new analysis shows.
Brian Buijsse, MSc, and colleagues address the account in the Archives of Internal Medicine. They advised 470 aged men for 15 years, tracking the men's amber consumption, including chocolate.
Cocoa assimilation was angry to lower claret burden and bargain afterlife risk, the abstraction shows. Natural compounds in amber alleged flavanols may be the reason, address Buijsse and colleagues.
However, it's "much too aboriginal to achieve that amber foods are acceptable for cardiovascular health," Buijsse tells WebMD in an email.
Buijsse works in the Netherlands' Center for Nutrition and Health, which is allotment of the National Institute for Public Bloom and the Environment.
Participants were 65-84 years old back the abstraction started in 1985. They were interviewed for an hour in their homes about the foods they ate.
Follow-up interviews were done bristles and 10 years later. All interviews were done in the attendance of whoever able the men's foods, if the men didn't baker for themselves.
The advisers acid in on 24 foods that accommodate cocoa, including amber cookies, amber bars, amber pudding, and amber drinks. Then, they affected those foods' amber content.
Here's a attending at amber burning in the study:
Cocoa eaters were added acceptable to booze alcohol, eat basics and seeds, and absorb low- or medium-fat dairy foods, bathetic confections, cookies, and agreeable foods.
The advisers didn't ask anyone to change their diets. Instead, they empiric the men's amber consumption, claret pressure, and deaths.
"The key bulletin is that our abstraction suggests that application low amounts of amber foods on a circadian basis, according to about 10 grams of aphotic chocolate, may lower claret burden and CVD [cardiovascular] death," Buijsse tells WebMD.
He calls for added studies, including some that anon analysis cocoa's bloom furnishings by allotment bodies to absorb cocoa.
"Although there accept been a few baby action studies published, the bulk of amber in these studies was huge -- in best cases 100 grams per day -- and the aftereffect continuance was absolutely abbreviate (a few weeks)," Buijsse says.
"These studies accept acutely apparent that amber lowers claret burden and improves endothelial function. Now it is time to abstraction whether there is a 'threshold' in the dosage of chocolate. So, action studies that use lower amounts of aphotic amber or amber booze with continuance best than a few weeks are interesting," he continues. Endothelial action is the alive of claret vessels' close lining.
"Of course, we charge to analysis whether the amber flavanols are responsible," Buijsse says "A afresh appear abstraction absolutely indicates that they are. This needs to be confirmed."
His abstraction tracked cocoa, not flavanols. That may be a weakness in the study, says Norman Hollenberg, MD, PhD, who afresh appear a altered abstraction on amber and claret pressure.
Hollenberg's study, appear in Proceedings of the National Academy of Sciences, was adjourned by the bonbon aggregation Mars Inc., which is developing flavanol-rich amber products.
Cocoa is usually candy to abolish bitterness. "Unfortunately, the acerbity is the flavanoids," Hollenberg tells WebMD. Flavanols are a blazon of flavanoid.
"I am acquainted that during the assembly action of amber (especially alkalization and baking of the amber beans), a allotment of the flavanols is burst down," Buijsse says. "This may be accurate to some extent, but commercially accessible amber foods still accommodate flavanols," he says.
"Although the flavanol agreeable of commercially accessible amber foods is lower than that acclimated in assertive action studies, our after-effects advance that these foods may still apply an aftereffect on cardiovascular health," Buijsse continues.
Even so, there's acceptable acumen not to go abdicate with amber and chocolate.
"Chocolate contains endless of calories because of the amoroso and fat in it," Buijsse writes. "If bodies eat a lot of chocolate, they accordingly accretion weight. And accepting a aerial anatomy weight is a above accident agency for aerial claret burden and CVD."
The Dutch abstraction shows "evidence of protection, but we don't apperceive how abundant amber produces how abundant protection, and whether a ample bulk of amber would aftermath alike added protection. We aloof don't know," Hollenberg says.
Like Buijsse, Hollenberg mentions a charge for interventional studies.

Such studies amount "easily tens of millions and frequently hundreds of millions of dollars, and they booty years to do, and you can alone do a bound cardinal of them," Hollenberg says. "So we use affirmation from empiric studies of this array to body our courage. And so we are still architecture our courage."
