Chocolate and runners

"Chocolate! I try to stay away from it!!!" commented my client, a runner who described herself as having a rampant sweet tooth. For her, chocolate fits into the categories of junk food, guilty pleasure and ruiner of good intentions to lose weight. Yet, she also recognized there is potentially a happier side of the story. Ads for (dark) chocolate suggest chocolate is good for us. Chocolate comes from plants and contains the same health-protective compounds that are found in fruits and vegetables.

So what is the whole story on chocolate? Is it little more than an alluring form of refined sugar, saturated fat and empty calories? Or does chocolate (in moderation, of course) have positive qualities that might be beneficial for athletes? Here are some nuggets of information about chocolate. I will let you decide whether or not the health benefits of eating chocolate are greater than the health costs — and if you personally want to define chocolate as a "health food" within the context of your own sports diet.

The bad

The bad news is chocolate consists of primarily saturated fat and sugar. A regular-sized chocolate bar (43 grams) contains 210 calories, 24 grams sugar (46% of calories), 13 grams of total fat (55% of calories) and 8 grams of saturated fat, equivalent to a tablespoon of butter. Boo hoo. (But here is how you can rationalize including this popular treat in your overall well-balanced sports diet: the fat in chocolate does not raise bad cholesterol levels and the sugar, carb, in chocolate fuels your muscles...).

People tend to eat chocolate in bursts — a lot in a day, such as on holidays or pre-menstrually — or none. The question arises: would enjoying some chocolate every day help reduce an athlete's urge to binge-eat the whole box of chocolate pralines in a moment of weakness? That is a good question and one that needs to be researched. We do know that deprivation and denial of food contributes to overeating. You know the syndrome: "I'm starting my diet Monday morning, so Sunday is my last chance to eat chocolate..." and there goes the whole box of pralines! I invite my clients to try taking the "power" away from chocolate by enjoying a little bit every day, such as for dessert after lunch. Ideally, daily chocolate could reduce it to being simply a commonplace plant food, just like bran cereal, an apple or carrot sticks. Give it a try?

The ugly

Some athletes claim they are addicted to chocolate. Perhaps "chocolate addicts" grew up in a household where the parents banned chocolate? Now, as grown-ups, maybe they rebel by eating chocolate by the bagful? Or are they "super tasters" — and the flavor of chocolate is just irresistible? Perhaps they have a genetic difference that makes chocolate highly attractive? Some day, genetic testing may help us find the answer to that question.

The good

Chocolate is made from cocoa. Cocoa comes from a plant. It is a rich source of health-protective phytochemicals, just like you would get from fruits, vegetables and whole grains. Two tablespoons natural cocoa power (the kind used in baking) offers the same antioxidant power as 3/4 cup blueberries or 1.5 glasses red wine.

Of all the types of chocolate, dark chocolate is the richest source of phytonutrients. Unfortunately, dark chocolate has a slightly bitter taste and most people prefer the sweeter milk chocolate. Maybe we should raise today's children on dark chocolate, so they will they learn to prefer it...?

One phytochemical in cocoa is nitrate. Nitrate gets converted into nitric oxide, a chemical known to increase blood flow. Nitric oxide lowers blood pressure, a good thing for aging athletes who want to stay youthful and invest in their health.

Another group of phytochemicals are called flavonoids. They are in many plant foods, including tea, apples and onions. Epidemiological surveys of large groups of people indicate those who regularly consume chocolate consume more of these health-protective flavonoids than non-chocolate eaters. This reduces their risk of heart disease. In the Netherlands, elderly men who routinely ate chocolate-containing products reduced their risk of heart disease by 50% and their risk of dying from other causes by 47%.

Cocoa increases blood flow to the brain. If this means you can process information better and faster — like calculate your split times or help your kids with their math homework — wouldn’t that be a great excuse to enjoy chocolate?!

Many parents keep chocolate away from their children, thinking chocolate makes them hyper. No research to date supports that claim. The party or special event that surrounds the chocolate likely triggers the hyperactivity.

Chocolate is yummy! Most athletes love chocolate. Chocolate lovers don't want sugar-free or fat-free chocolate. They want the 100% real stuff! That's because consumers buy benefits, not products. Being yummy is a huge benefit! Also, chocolate seems to fit every mood, be it happy, sad, tired or celebratory.

Flavanol-rich cocoa may help reduce muscle soreness. Studies with athletes who performed muscle-damaging downhill running and then consumed a cocoa-based carbohydrate and protein beverage experienced less muscle damage and felt less muscle soreness.

Although the chocolate used in flavoring milk lacks the health-protectors found in dark chocolate, the yummy flavor makes chocolate milk a popular recovery drink. The sweetened chocolate offers carbs to refuel muscles; the milk offers protein to build and repair muscle. Plus, milk boosts intake of calcium and vitamin D, needed for strong bones.


Despite all this good news about chocolate, it is still just a candy and not a life-sustaining food. Yet, it does provide pleasure — and pleasure is certainly part of a health and wellness program, right? The trick is to enjoy dark chocolate as part of the 100 to 150 discretionary sugar calories that can be part of your daily sports diet. As for me, I'll enjoy my dark chocolate during a long hike or bike ride. Tastes better than most engineered sports foods and nicely fuels both my body and my mind!
