Is chocolate good for your heart?

Cocoa has been long been known for its good taste. But several epidemiological studies and some small prospective studies have shown that cocoa exerts beneficial cardiovascular effects. These beneficial effects seem to be mediated by its polyphenols, especially flavanols, a group of natural chemicals found primarily in fruits and vegetables.

The beneficial effects of cocoa include improvement in endothelial function (the lining of your artery wall), the reduction in platelet function (decreasing the chances of a blood clot), and the potentially beneficial effects on blood pressure, insulin resistance, and blood lipids.

But before you rush out to stock up on chocolate, know this: the manufacturing process to make chocolate from cocoa seeds significantly decreases the concentration of the flavanols. Milk chocolate in particular has the lowest flavanol content compared with cocoa powder and dark chocolate.

And many chocolate products contain milk or processed fats, e.g., palm oils. Your best bet – cocoa powder itself (especially raw cacao powder) because, unlike chocolate, it is low in sugar and fat.

And when you crave a chocolate fix – look for dark chocolate, particularly those with more than 80% cacao. Everything in moderation!

Why 96,000 Square Miles?

President Robertson is fond of saying that OHSU has a 96,000 square mile campus, serving Oregonians “from Enterprise to Coos Bay, from Portland to Klamath Falls.”

This blog aims to highlight that breadth. 96,000 Square Miles (96K for short) will focus on the people of OHSU, the Oregonians we serve and the ripple effect of our work in Oregon and beyond.
