Cocoa Improves Brain Blood Flow

This is extraordinary information of the food value of cocoa in support of human health.  The present difficulty is that we have never tried to develop food products that are actually safe to eat continuously like we do with tea and coffees.  Sugar and fat laced bars are neat as occasional calories but no one will argue continuous use.

This informs us that the problem now needs to be revisited.

Here is a simple potation inspired by the Aztec version.  Notice the substantial vanilla and lack of sugar.  Other recipes add other spices such as anise which suggests there is ample room for experimentation.

1 ounce unsweetened baking chocolate
1 teaspoon vanilla
2/3 cup boiling water
ground pepper of chilies to taste

Dry cocoa powder has all the oils removed and lacks richness.  Yet it also lends itself to a plausible beverage as we do when we blend it with milk to replace the removed oils.

The take home message for habitual users is to simply eliminate the sugar and take it from there.  If you are brave, this is also a great way to imbibe a daily dose of chili.

This item tells us that finding new ways to use cocoa is a good commercial idea whose time has come.  It is no longer solely part of the luxury trade.

Researchers link cocoa flavanols to improved brain blood flow
August 18, 2008

Cocoa flavanols, the unique compounds found naturally in cocoa, may increase blood flow to the brain, according to new research published in the Neuropsychiatric Disease and Treatment journal. The researchers suggest that long-term improvements in brain blood flow could impact cognitive behavior, offering future potential for debilitating brain conditions including dementia and stroke.

In a scientific study of healthy, older adults ages 59 to 83, Harvard medical scientists found that study participants who regularly drank a cocoa flavanol-rich beverage made using the Mars, Incorporated Cocoapro® process had an eight percent increase in brain blood flow after one week, and 10 percent increase after two weeks.

In this first-of-its-kind study, the researchers found both short and long-term benefits of cocoa flavanols for brain blood flow, offering future potential for the one in seven older Americans currently living with dementia. When the flow of blood to the brain slows over time, the result may be structural damage and dementia. Scientists speculate that maintaining an increased blood flow to the brain could slow this cognitive decline.

"The totality of the research on cocoa flavanols is impressive. This is just one more study adding to an increasing body of literature connecting regular cocoa flavanol consumption to blood flow and vascular health improvements throughout the body," said Harold Schmitz, Ph.D., chief science officer at Mars, Incorporated, which has supported research on cocoa flavanols for more than 15 years. "Though more research is needed, these findings raise the possibility that flavanol-rich cocoa products could be developed to help slow brain decline in older age."

Contrary to statements often made in the popular media, the collective research demonstrates that the vascular effects of cocoa flavanols are independent of general "antioxidant" effects that cocoa flavanols exhibit in a test tube, outside of the body. While research aimed at studying the potential role of cocoa flavanols in the context of blood vessel and circulatory function continues, a number of previously published studies already suggest that the consumption of cocoa flavanols can have important beneficial effects on the function of the body's network of blood vessels. The body of research not only suggests that cocoa flavanols may provide a dietary approach to maintaining cardiovascular function and health, but also points at new possibilities for cocoa flavanol-based interventions for vascular complications associated with cognitive performance, skin health and age-related blood vessel dysfunction.
