Human studies have shown that the consumption of cocoa can improve insulin sensitivity (which lowers blood sugar) and reduce blood pressure, two risk factors which can lead to cognitive decline.  Cocoa also causes vasodilation, which improves blood flow leading to increased brain blood flow (always a good thing).  A 2012 human study confirmed that consumption of a drink enriched with cocoa flavanols improved cognitive function in elderly adults with mild cognitive impairment (MCI).  Desideri G et al. Hypertension 2012;60:794-801. Because cocoa has been shown to increase blood flow to the brain (both 450 mg/day of cocoa flavanols and 993 mg/day of cocoa flavanols have been reported to have this effect)- Sorond FA et a. Neuoropsychiatr Dis Treat 2008;4:433-40.   My favorite method of daily cocoa “consumption” is 8 ounces of vanilla soymilk microwaved for 45 seconds, add one packet of CocoaVia (which contains 375 mg of cocoa flavanols/packet), and honey “to taste” .  A 2015 study by Daniela  Mastroiacovo concludes: “This dietary intervention study provides evidence that regular Cocoa Flavanol consumption can reduce some measures of age-related cognitive dysfunction, possibly through an improvement in insulin sensitivity.  These data suggest that the habitual intake of flavanols can support healthy cognitive function with age”.  Am J Clin Nutr...
