TODAY'S TOPIC: THE BEST WAY TO ROAST COFFEE
Thanks to its antioxidants, coffee lowers your risk of major diseases like diabetes and heart disease, and offers athletes a boost in performance and reduction in recovery time.
But there are two types antioxidants in coffee, says Kwang Suk Ko, Ph.D., study author and assistant professor at Ewha Womans University in Seoul: chemicals that structurally have their own antioxidant function, like polyphenols, and chemicals that boost the antioxidant function of your cells, like caffeine. “We found that more roasting broke or changed the polyphenols' structure,” he explains. Meanwhile, caffeine, which is stronger against heat, stayed intact even at a higher temperature and longer roasting time.
Most of the disease protection has to do with coffee’s antioxidants battling oxidative stress, so a lighter roast (which has been roasted for less time) might indeed protect your health better than a darker one, Ko says. But when it comes to athletic performance, Ko says the perks are mainly from caffeine’s stimulation of your central nervous system, so the roast level won’t matter much.
