Harvard Medical School: "Your brain on chocolate"


“…For, after all, I had been into cocoa a bit myself. That was back when The Great Winfield had discovered cocoa trading. Occasionally in those more leisured days I would sit with him lazily watching stocks move, like two sheriffs in a rowboat watching catfish in the Tennessee River….”
-'Adam Smith', Supermoney


We'll probably be looking at cocoa a bit more over the coming weeks $1883/tonne, down $9.00.

From Harvard Medical School:
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:
  • Short-term consumption may be helpful. For example, a 2011 study of young adults found that two hours after consuming dark chocolate (with high flavanol content), memory and reaction time were better than among those consuming white chocolate (with low flavanol content). However, other similar studies showed no benefit.
  • Long-term consumption may be helpful. One 2014 study found that among adults ages 50 to 69, those taking a cocoa supplement with high flavanol content for three months had better performance on tests of memory than those assigned to take a low-flavanol cocoa supplement....
