Semi-sweet news for chocolate lovers

Editor's note: Watch Dr. Sanjay Gupta Reports: The Last Heart Attack at 8p and 11p ET on Saturday, September 3rd.

If only everything that looked good, felt good, or tasted good was good for us too. It comes as more welcome news for chocolate lovers, then, that yet another study has linked chocolate consumption with improved heart health. Maybe.

Researchers at the University of Cambridge analyzed the results of seven existing studies and concluded that high levels of chocolate consumption might be associated with a notable reduction in the risk of developing heart disease. Five of the seven studies reported a beneficial link between higher levels of chocolate consumptions and the risk of cardiovascular events. They found that “the highest levels of chocolate consumption were associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke, compared with the lowest levels [of consumption].”

The studies, notably, did not differentiate between dark or milk chocolate and included consumption of different types of chocolate (bars, shakes, etc.)

"The observations represent associations, not cause and effect," says Alice Lichtenstein, director and senior scientist at Tufts University's Cardiovascular Nutrition Laboratory. "The results of the evidence review provide support for conducting controlled intervention trials using well-defined preparations of chocolate before we can determine the actual effect of chocolate on heart disease risk."

By the year 2030, the World Health Organization estimates that nearly 23.6 million people will die from heart disease. In CNN Chief Medical Correspondent Dr. Sanjay Gupta’s documentary “The Last Heart Attack,” Dr. Caldwell B. Esselstyn, Jr. asserts that simply modifying one’s diet can make a person heart attack-proof in just one month. Should chocolate then be prescribed as part of this diet, which advocates the consumption of a plant-based food plan?

A number of recent studies have shown that eating chocolate has a positive impact on human health, thanks to its antioxidant and anti-inflammatory properties, namely reducing blood pressure and improving insulin sensitivity.

But here’s the caveat. Chocolate, as we all know, is full of calories, and eating too much of it could lead to weight gain, diabetes, or even heart disease – the very ailment some believe chocolate is working to prevent in the first place.

The authors of the study stress that further testing is needed to determine whether chocolate actually causes this reduction in heart problems, or if the health benefits are instead better explained by some other unmeasured factor.

"Were there compounds in cocoa that decrease heart risk," says Lichtenstein, "it will be important to identify them, isolate them, and determine the optimal dose and best route to administer them."

One thing is clear. Chocolate does far more for our bodies than activate our taste buds. Given its apparent health benefits, some resources might now be shifted to exploring the fat and sugar contents of chocolate, and how we might go about lowering them. This new “superfood” would be quite sweet indeed.

      I've always loved chocolate... the darker, the better. It even helps with Dementors (if you know "Harry Potter").
      Always thought it was good stuff. Then, it becomes more clear. Does a quote like:

      "Were there compounds in cocoa that decrease heart risk," says Lichtenstein, "it will be important to identify them, isolate them, and determine the optimal dose and best route to administer them."
      ...sound like it came from Big Pharm ?

      They're taking all the fun out of eating chocolate. It's sweet, delicious, and full of calories. I eat chocolate because it tastes good, not because it may/may not be good for me.

    Moderation kills. what's your definition of moderation? 5 chocolate bars a week instead of 12? "Moderation" is code word for "Lazy". Either eat it or don't. The average American definition of moderation is excess. That's why our "moderation" country became fat. I can't believe people would eat crap and feel like crap than eating well and feeling well. Nothing tastes as good as how healthy feels.

    The cardiovascular related benefits they found are probably related to a separate study which demonstrated that people who consume chocolate tend to workout more than those who don't. It makes sense, if you eat something unhealthy, you should workout to compensate for the extra calories. If chocolate does have anti-oxidant effects then it's just a double-bonus!

      Chocolate – especially best-quality chocolate, with high cocoa mass– gives far more satisfaction for fewer calories than, say, a sleeve of cookies or similar junk sweets. People who really appreciate good chocolate are more apt to eat smaller portions of it.

    Another worthless observational study makes another unfounded conclusion. People need to understand that observing correlations can only be used to form a hypothesis, and never to draw conclusions or recommendations – not even through meta-analysis like this study. What is necessary now is a clinical study. Only then can you determine whether there is an actual cause.

    Shame on the Franco for poor science. Just because it's popular in dietary science to draw conclusions from correlations doesn't mean it's valid.

      I actually thought the article was pretty good about noting that correlation does not imply causation. It also ended by saying what you just commented, that clinical trials of chocolate are needed to establish any actual benefit from chocolate. So please forgive me if I don't understand why you're complaining.

      While there are certainly limits to correlative observational studies, they certainly are not "worthless." While proving causation is difficult with correlative studies (something that the article fairly pointed out), a well-designed correlative study can provide very strong evidence to support a hypothesis. By your logic, we have no evidence that seat belts save lives, because we have never done a double-blind study in which participants are randomly assigned to not wear seat belts.

      Unfortunately, nutritional clinical studies are extremely difficult, because you would have to entirely control the food intake of participants. This can be done (I have been involved in studies where participants need to come to the research site for every meal and snack); the problem is that what it really relevant for nutrition is long-term effects, and obviously it is not feasible to perform such studies for the decades required to monitor such effects. Additionally, people cheat and eat things that they are not supposed to, so even clinical trials have sources of error.

    Can we please get out of grade school and expand our research capabilities a bit? Cocoa has benefits that have been observed for centuries (even before we contaminated it with sugar and emulsifiers). Cocoa powder can be bought – gasp – sugar free! Stick ONLY with DARK chocolate at 82% or higher; one ounce a day (which is really quiet enough to satisfy). Many "dark" chocolate brands are not really very "dark" at all. Keep it as pure as possible, being sure that the cocoa used is not contaminated with lead (as some is from growing near roads in countries that still allow leaded gas). Be sure the cocoa is harvested fair trade (meaning no slave labor). This matters greatly. A good 82 % dark will cost more, but at one ounce a day, it's a good investment. Also don't depend solely on cocoa. Get LOTS of color from all kinds of fruits and vegetables. The fiber from produce matters just as much as the color.

    I eat a couple of squares a day of low sugar, extremely dark chocolate (88%). I've given some to friends and family, at first they could not handle it "too bitter, not sweet enough", but some of them later say "hey, I'm actually liking this, now the candy type of chocolate is too sweet for me". My gut feeling is the low cacao content, milk chocolate has minimal positive health impact.

    Forget to mention in the above note that when purchasing cocoa powder, one can then use STEVIA to sweeten with milk, soy milk, almond milk, etc. Tofu, cocoa and walnut oil can make a nice "mousse" when whipped in a food processor. The 82% comes in when selecting chocolate bars. The higher the number, the less sugar. And the dark is an acquired taste. Test out different brands as each does have a different character. There are many places to get chocolate but the supermarket is probably not going to carry much of an 82% or higher unless you ask them to stock it. You can compare different brands at sites such as Chocosphere.com - look ONLY for 82% – no less. And teeth still need to be rinsed well afterward. If enjoyed with NUTS, that stretches the treat, adds good fats and protein that help balance blood glucose. Again, though, only 82% or higher. It does matter greatly. You'll be surprised that one ounce is all you'll likely want. Enjoy.

    Your fat bias is showing. The body needs fats, the body does not need sugars. Eat 'good' fats in a reasonable amount and cut way back on the sugars and you'll be healthier.

      The body need essential fatty acids, and cocoa has almost none–about 3% of the fat is linoleic (omega-6). Cocoa fat is about 1/3 stearic acid (sat'd, but neutral effect on blood lipids), 1/3 oleic (mono-unsat'd, neutral effect on blood lipids), and about 25% palmitic (sat'd) which some research has implicated in raising LDL cholesterol. Moderation is likely best, or cocoa powder, as it is far lower in fat than dark chocolate–~14% vs. 43% and you eat a lot less of it.

      Correct. A colleague went on a totally fat-free diet and after just a few weeks, her skin and hair looked dreadful. Some amount of fat is necessary; most people eat way too much.

    Natural unsweetened cocoa powder from Ghiradelli has 55,653 ORAC. Wild blueberries are around 10,000. Chocolate in its pure form is a superfood beyond compare. Add a little peanut butter and you have a combination for superior absorption of the antioxidants...try it, you will no doubt love it.

    So why the pics of fudge? Half of them are not even chocolate.

    For the ORAC fanatics: don't lose sight of the forest here–chocolate is not going to fix everything that ails you, and besides, free radicals are needed for bodily defenses. Not wise to quench it all. Keep some perspective here.

      Why wait? Make your own. Melt baker's chocolate and add as much cocoa powder as you want and as much sugar (or Splenda) as desired. Then allow to harden and enjoy–if you can. It may be disgustingly bitter and have a so-so mouthfeel. 😉

    Chocolate... semi-sweet... about 70% is served best with a red Medec or Cabernet-Sovignon. give more of the chocolate to your girlfriend over candle light. Perhaps even melt some over ripened strawberries and hand feed them to her. You might get some loving thereafter..... The resulting physical activity will result in an elevated heart rate, comperable to any aerobic activity, and the natural release of hormones that provide and equal to any runners high. The result usually is medically proven to be a highly mind-tempering state.....approved by psychologists worldwide.....

    By chocolate, they are not talking about that delicious milk chocolate stuff pictured above, or white chocolate, which is not chocolate at all. They are talking about semi sweet to bitter chocolate, something like baker's chocolate. I am not a big chocolate fan, but I like it once in awhile.
