after the Spring Festival, Festival apart from most young people concerned about the holiday is Valentine's Day. Valentine's essential activity is of course the beloved person to the gift of chocolate. So, chocolate has become a hot commodity, the Healthy Chocolate also re lively topic. A television cooking program that can be assured that eating chocolate will not cause obesity! A newspaper said, chocolate and candy are not the same, its good for the heart! Is this in the end? What kind of chocolate should be good for people? May wish to take a look at the latest research reports.
American Journal of Clinical Nutrition at in July 2008 published a study of different chocolate and cocoa beverages was tested. Researchers put 45 overweight volunteers were divided into two groups, one group to contain 22 grams of cocoa powder and chocolate (of the bitter taste of dark chocolate), another group does not contain cocoa powder to chocolate; And then subjects were divided into three groups, one group does not give the cocoa sugary beverages (including cocoa powder 22 grams), the other group are sugary sweet cocoa beverages (cocoa powder containing the same 22 grams), the third group are sweet cocoa flavored drinks (which do not contain cocoa powder). Disposable after use and immediately measured the changes in physical indicators.
found that taking sugar-free cocoa beverage people, to improve endothelial function in the role of the strongest, sugary clearly some bad, but still more than non-drinking cocoa drinks were a little better. From the perspective of blood pressure, drink sugar-free cocoa, cocoa powder chocolate to eat an average blood pressure fell by 2-3 mm Hg, while it is undeniable could eat chocolate powder or cocoa beverages, blood pressure did not decline, but there is 2-3 mm Hg rose column.
another published in the 2005 study subjects were 15 consecutive days to take dark chocolate (100 grams weight, with more than 500 mg phenol), or white chocolate (It can not be components, very low polyphenol content), then exchange the two groups confirmed that eating dark chocolate can improve insulin sensitivity, reducing insulin resistance, at the same time be able to mildly lower blood pressure. White chocolate is not such a role.
researchers think, cocoa polyphenols in chocolate produced ingredients are the source of health effects, several studies confirmed that cocoa powder can provide substantial antioxidant components, reducing blood clotting, reduce blood pressure, improve vascular endothelial function and erythrocyte deformability. Sugar and cocoa powder fat other than cocoa powder would reduce this effect, there is no so-called chocolate cocoa products and cocoa flavor drinks without any health effects, and may even be opposite.
Looking at the current market our country chocolate contains cocoa ingredients low sugar content as high as 50%. Although this kind of chocolate, sweet and delicious, but very difficult to talk on health effects. It is gratifying that some large supermarket inside a high content of cocoa products, cocoa content up to 65% from 90%. But this bitter taste of chocolate, heavy, sweet very short, or no sweetness, the majority used to eat chocolate candy consumers when difficult to accept.
In fact, chocolate and chocolate is not exactly the same as the concept of Taste is bitter chocolate, and chocolate is a sweet thick . The so-called hot chocolate drinks, nor is it really chocolate products, which contain a lot of hydrogenated vegetable oil, have many sugar.
chocolate because the value of being bitter in its polyphenol components, and certainly not one of the sugar and milk, vegetable oil refining, and even on behalf of cocoa butter. White chocolate have no intrinsic health value, but also because substituting cocoa butter and contains too much sugar, are harmful to the heart.
at the beautiful Valentine's Day give your loved one an IM conversation, of course, can be used with higher sweetness of chocolate, but if for themselves and their families often enjoy words, or select high-sweetened cocoa or sweet products more wisely.
In fact, the same feelings, with Gambari, but also want to share adversity, is worth the love cherish; there is a little bit bitter and difficult before the Living more memorable.
