Here’s another study showing that chocolate can have a beneficial health effect. In this particular case, 1 to 2 servings of dark chocolate a week was found to correlate with a reduced incidence of heart failure.
BUT the study comes with a key caveats: daily or near daily chocolate consumption suggested no beneficial health effects. As the NY Times write-up said, “too much chocolate can cause weight gain, offsetting its benefits.”
My chocolate consumption is pretty irregular since I tend to taste and photograph a lot in a single day. At least they didn’t report a negative effect of excessive chocolate consumption! Well, aside from weight gain.
