Americans eat 2.8 billion pounds of chocolate a year, enticed by catchy slogans like “Do you dream in chocolate?” And folks are encouraged to indulge by the numerous scientific reports that chocolate is good for you — well, at least 70% dark chocolate is, in 1-ounce-a-day doses. But that, we worry, makes folks who vape think chocolate-flavored electronic cigarettes are healthy, too. Far from it.

A new study found that of all the lung-polluting elixirs added to e-cigs, chocolate flavor (with a high dose of what the researchers say is benzene-ring flavorings) is the most harmful. According to the study published in the American Journal of Physiology/Lung, Cellular and Molecular Physiology, it delivers a brew of toxins that can kill off lung cells and reduce the ability of your immune system to remove bacteria and regulate inflammation. Banana, cherry and cinnamon flavored vapes aren’t much better for you.

So while dark chocolate — with its anti-inflammatory powers — is a smart choice for a sweet treat, you want to eat it slowly and savor a 1-ounce portion. Don’t inhale it!

It’s amazing to think that in 1929, Popeye actually knew more than nutritionists about what it takes to build muscle power and function. It’s only recently that researchers published a study in the Journal of Nutrition explaining that a nitrate-rich diet — predominantly from leafy, green veg…
