Wait, what are purple sweet potatoes?
I can not say I always knew what they were, but about 5 years I discovered this amazing root at the store! At first I just thought it was a colorful sweet potato, until I started doing some research! Purple sweet potatoes are high in the flavonoids: cyanidnin and peonidin. These two anthocyanin have been shown to reduce inflammation by lowering COX-2 levels, MCP-1, and IL-6! For my friends in medicine, we know these inflammatory markers all too well! At first I was skeptical, I figured all the studies were in vitro with 1000x concentrations, but to my relief there are human studies showing the effects on participants’ metabolic factors, hepatic function tests, and inflammatory markers.
One thing that fascinates me is that these are one of the staples in the Okinawan Diet! A population that is known for longevity, reduced risk of cardiovascular disease, and reduced risk of other chronic age-associated diseases.
