Why You Need Chocolate

It can heal your heart and mind — but you have to eat the right kind. Here's what to avoid, what to indulge in

If it hasn't occurred to you to toss chocolate shavings into a salad, shake cocoa powder over a bowl of popcorn, or serve chicken with a savory chocolate mole sauce, now might be a good time to ask yourself why. Scientists are finding that chocolate — or, more specifically, cocoa powder made from ground, defatted cocoa beans — contains compounds that have the potential to protect against heart disease, stroke, cancer, and diabetes.

Cocoa beans contain substantial amounts of antioxidants, dietary substances that mop up free radicals. (The cell damage they cause can lead to cancer-triggering mutations or blood-vessel scarring that accelerates heart problems.) Disease-fighting antioxidants are also present in blueberries, kale, spinach, tea, red wine, and grape juice. But chocolate is a particularly potent source; ounce for ounce, dark chocolate has five times as many antioxidants as blueberries.

Food scientists are no longer shy about praising chocolate, and not just as a dip for strawberries. Several studies have demonstrated that antioxidants in chocolate — known as flavonols — help lower levels of "bad" LDL cholesterol while boosting "good" HDL cholesterol. Flavonols seem to ease inflammation, opening blood vessels and improving blood flow. These antioxidants can prevent platelets from adhering to the lining of blood vessels, inhibit blood clotting, and help prevent plaque formation in the arteries, explains Carl L. Keen, PhD, chairman of the nutrition department at the University of California, Davis. "The science is compelling. I think it's a good idea to include flavonol-rich foods such as chocolate in your diet," Keen says.

And like a quality bar of Valrhona, the research keeps getting better. A recent Italian study confirmed that dark chocolate can decrease blood pressure; it also revealed that the dark stuff may help prevent type 2 diabetes by encouraging hormones to transport sugar from the blood into cells for fuel. In another study, published in March, soccer players in Argentina who ate 3.7 ounces of milk chocolate every day for 2 weeks had improved markers of cardiovascular health, including lower blood pressure, LDL cholesterol, and total cholesterol than soccer players who ate white chocolate (which contains few flavonols).

In April, Georgetown University researchers reported that when human breast cancer cells were treated with pentamer — yet another antioxidant found in cocoa — it interrupted the rapid growth that can lead to tumors. It's too early to tell whether pentamer would act the same way in the body as it behaves in a test tube, but if it does, it could have potential as a cancer treatment.

Before you blow next month's grocery budget at Godiva, just remember that the stuff is high in calories. To get the biggest health (and flavor) bang for your buck, you really have to eat the right kind. Happily, the government has been on the job to determine which chocolate is the best. A recent study by the USDA's Agricultural Research Service revealed the antioxidant content in various types, and in April, results were presented at a major science conference. The research revealed that the more cocoa powder the chocolate contains, the more antioxidants you're getting. Here's how the USDA analysis ranks chocolate products, along with some of the healthiest recipes that deliver a flavorful and nutritious punch:

Natural Unsweetened Cocoa Powder

To make chocolate, a manufacturer crushes roasted, fermented cocoa beans, or nibs, into a liquid called chocolate liquor. The liquor can be pressed to separate out its fat (cocoa butter). What remains is a cocoa "cake" (also known as cocoa solids) that can be ground up to become natural unsweetened cocoa powder. This has the highest level of cocoa flavonols because it's the least processed. Also, because the fat has been removed and it contains no extra ingredients such as sugar, it's the healthiest form of chocolate you can find. But it tastes bitter, so you're not about to eat it by the spoonful. Hershey's Cocoa is probably the best known and is fine for everyday use. For a treat, try Scharffen Berger Natural Cocoa Powder (Scharffen Berger Chocolate Maker).

To include natural unsweetened cocoa powder in your diet, sprinkle it into coffee, yogurt, or cereal; stir it into batters for banana or zucchini bread; or use it to make quick, delicious hot chocolate.

I love dark chocolate with nuts. Up to 86% pure chocolate is good. Smile

I suggest the touted health benefits of chocolate is an unsubstantiated mythe. Chocolate is right up there with tea and coffee and sugar. Health benefits zilch, particularly with regards with the quantity consumed. It is just a social custom.

The same thing applies to ginseng.
