Chocolate May Lower Cholesterol

Wednesday, June 2nd, 2010

Just say the word chocolate and most people start salivating like a grizzly Rottweiler staring down a mailman.

And not only is chocolate a god among confectionaries, but it’s also been linked to a variety of health benefits; such as protecting against heart disease.

Chocolate has earned that reputation because of its high concentration of antioxidants, which have been shown to reduce oxidation; a risk factor for cardiovascular disease.

And now, published in the American Journal of Clinical Nutrition, researchers say consuming small amounts of chocolate – sorry, only 6 grams – may lower cholesterol levels in some people.

Individuals who already had heart disease showed a reduction in LDL, or “bad,” cholesterol when eating modest amounts of chocolate – so you shouldn’t devour an entire bag of Hershey’s Assorted Miniatures.

And chocolate’s effect on reducing cholesterol was attributed to polyphenols – surprise-surprise, an antioxidant. A 1.25 ounce bar of chocolate contains roughly 300 milligrams of polyphenols.

But if you don’t like chocolate, or are more of a vanilla person – or shudder the thought, a strawberry person – polyphenols can also be found in vegetables and wine.

Chocolate Linked to Depression, Oh No!

Tuesday, May 4th, 2010

Bad day at work, get depressed, pound a gallon of triple chocolate ice cream. Yeah, we’ve all done it…guilty!

And new research confirms the link.

Writing in the Archives of Internal Medicine, experts found depressed people consume 55% more chocolate than non-depressed individuals.

Out of the 900 study participants, depressed men and women ate 8.4 servings of chocolate a month, compared to non-depressed participants who only ate 5.4 servings.

But researchers do not claim eating chocolate causes depression. Instead, it might just be a good pick-me-up for people feeling down.

Makes sense, everyone likes chocolate!

Eating lots of chocolate desserts might not do wonders for your health, but chocolate – specifically the cacao seeds – is loaded with antioxidants.

Overeating and Dieting Linked to Addiction, in Rats

Friday, November 13th, 2009

RATQuitting a bad diet, and switching to a healthy one, might be just as difficult as kicking drug addiction.

When weaning rats off a high-calorie diet, researchers found similar effects on their brain to stopping drugs and alcohol.

Granted, rats and humans have very different brains—most of the time—but scientists believe these findings help explain why diets fail.

Writing in the Proceedings of the National Academy of Sciences, experts claim when overeaters try to go on a diet it causes stress hormones in their brains to run wild.

This freaks them out, leading to anxiety, decreased motivation, and unwillingness to try other foods. A similar effect is seen with drug addiction.

To test this out, researchers gave the rats regular food for 5 days, then switched them to a chocolate-flavored sugary food, and after eating the junk food, the rats didn’t want to go back to the regular stuff.

And when deprived of the sugar, the rats’ brains acted as if they were coming off booze or drugs.

Researchers say knowing how food effects the brain can help treat people with obesity.

Dark Chocolate Lowers Stress Levels

Friday, November 13th, 2009

DARKSure, devouring a pint of triple-chocolate ice cream will make anyone feel better, but we’re not talking about “comfort food” here.

Scientists at the Nestle Research Center in Switzerland suggest compounds in dark chocolate may lower stress hormones during times of high anxiety.

After feeding study participants, both men and women, half a chocolate bar, or roughly 20 grams, every morning, researchers monitored their stress hormone production for two weeks.

Findings showed “chocolate therapy” lowered high hormone levels.

So experts suggest stressed out workers would benefit long-term from daily consumption of chocolate. They recommend 40 grams a day. A whole candy bar, nice!

Researchers believe flavanols in chocolate, which help prevent artery inflammation, are also responsible for the reduction in mental stress.

But dietitians warn not to go overboard with chocolate, since it’s usually high in fat and sugar.
