The Health Benefits of... Food
Many of us have heard the adage 'Let food be your medicine and medicine be your
food" attributed to Hippocrates (ca. 400 BC). In the past century however, what
is deemed 'food" and 'medicine" has changed dramatically. Reading food labels
now requires at least one advanced degree just to pronounce the added
ingredients. This month, we highlight the health-improving properties of two
food ingredients that are known mostly for their flavor- cinnamon and chocolate.
Clinical Trial completed with Cinnamon extract used in Fenunol
Researchers at the USDA have been looking into the glucose regulatory properties of a number of common spices, including cinnamon, for many years. Previous evidence suggests that cinnamon improves glucose regulation in patients with Type 2 diabetes. New and promising data suggests that Cinnulin PF, a proprietary aqueous cinnamon extract standardized for doubly-linked type-A polymers, decreases fasting blood sugar levels and small but statistically significant changes in body fat and lean mass in otherwise healthy pre-diabetic men and women. This suggests that cinnamon may be an excellent candidate for improving insulin sensitivity and glucose utilization for nearly 25% of the US population (those with metabolic syndrome) For complete details on this trial, please see the poster presented at Supply Side West.

Dark Chocolate- Good for the Heart
Chocoholics have been receiving good news lately, as more research confirms the benefits of cocoa and the chocolate products made from cocoa. Researchers have found dark chocolate has the most benefit, while milk and white chocolate have little effect. Recently, a group in Switzerland published their findings in 25 'healthy" smokers, where they measured endothelial (inner lining of blood vessels) function by flow-mediated dilation (FMD) two hours after ingesting either dark (74% cocoa) or white (4% cocoa) chocolate. FMD improved statistically in subjects consuming dark chocolate while shear stress-dependent platelet adhesion was reduced, compared to subjects consuming white chocolate. Total antioxidant status also improved in the dark chocolate group. [Abstract]
We are likely to see much more research on various polyphenolic components found in cocoa and chocolate. Certainly, recruiting for long-term studies should not be difficult.
