Did you know that places where chocolate consumption is highest have the most Nobel Prize recipients? It’s true, at least according to a 2012 study published in the New England Journal of Medicine. Of course, that could be a coincidence. But is it possible that intelligence or other measures of high brain function are actually improved by the consumption of chocolate? A new review summarizes the evidence and concludes with a resounding “maybe.”
Keeping your brain healthy
When it comes to preserving and improving brain function, let’s face it: we need all the help we can get. With age, diseases that cause dementia, such as stroke, Alzheimer’s disease, and Parkinson’s disease, become more common. And since we have an aging population, predictions are that dementia will become much more common in the near future. Yet despite decades of research, there are no highly effective treatments for dementia.
As for preventive measures, the best recommendations are those your doctor would make anyway, such as regular exercise, choosing a healthy diet, maintaining a normal blood pressure, not smoking, and drinking only in moderation. “Brain exercise” (such as challenging math problems or word games) and a variety of supplements are unproven for long-term preservation of brain function or prevention of cognitive decline. While some studies suggest that antioxidants, fish oil, stimulants such as caffeine, or other specific foods may help improve brain function or prevent dementia, these benefits are hard to prove and studies have been inconclusive at best.
What’s the scoop on chocolate and the brain?
A new review published in the May 2017 edition of Frontiers in Nutrition analyzed the evidence to date that flavanols (found in dark chocolate and cocoa, among other foods) may benefit human brain function. Flavanols are a form of flavonoids, plant-based substances that have anti-inflammatory and antioxidant effects. Here’s a sample of the findings:

Every cup of coffee I drink has a scoop of cacao powder in it - great way to consume it. Take it in its raw form - all the bars have added sugar etc.
ReplyDeleteThanks! Great Idea. Have to try it.
