How coffee works
Coffee not only works thanks to caffeine and protects the brain in different ways. Three of them are through the caffeine, their polyphenols (which include chlorogenic acid and quinic acid), and the tregonelline. Uma Naidoo, psychiatrist and nutrition expert explains:
Caffeine. Caffeine increases serotonin and acetylcholine, which can stimulate the brain and help stabilize the blood-brain barrier.
Polyphenols. Polyphenols naturally found in caffeinated and decaffeinated coffee can act as antioxidants to reduce oxidative damage and inflammation of cells.
Trigonellin. Trigonelline can activate antioxidants, thus protecting the blood vessels in the brain.
Not only good for the brain
Drinking coffee regularly can reduce the risk of heart disease and stroke.
Coffee drinkers also have a lower risk of developing type 2 diabetes. Polyphenols and minerals like magnesium in coffee can improve the effectiveness of insulin and glucose metabolism in the body.
