More caffeine from coffee associated with decreased rosacea risk

October 17, 2018

BottomLine: Consuming caffeine from coffee but not from other foods (tea, soda and chocolate) was associated with less risk of rosacea, a common chronic inflammatory skin disease where the skin appears red and flushed. This observational study included more than 82,000 women in the Nurses' Health Study II with data collected on coffee, tea, soda and chocolate consumption. Compared with people who had less than one serving of caffeinated coffee per month, those who had four servings or more per day had the lowest risk for rosacea. Decaffeinated coffee wasn't associated with decreased rosacea risk. Rosacea symptoms may be lessened because of caffeine's vasoconstrictive and immunosuppressant effects but further studies are to needed to understand the reasons for the observed association.

The Flag and the Fury
How do you actually make change in the world? For 126 years, Mississippi has had the Confederate battle flag on their state flag, and they were the last state in the nation where that emblem remained "officially" flying.  A few days ago, that flag came down. A few days before that, it coming down would have seemed impossible. We dive into the story behind this de-flagging: a journey involving a clash of histories, designs, families, and even cheerleading. This show is a collaboration with OSM Audio.
