Morning Cup of Hot Coffee
That wonderfully warming cup of morning coffee may have health benefits. The caffeine in coffee stimulates the brain and nervous system, and may lower your risk of diabetes, Parkinson's disease, mood problems, headaches, and even cavities.
Scientists have discovered coffee's many beneficial substances, including chlorogenic acid, a compound in the antioxidant family that may improve glucose (sugar) metabolism. Another perk is that coffee contains magnesium, a mineral that can also improve insulin sensitivity and enhance glucose tolerance -- thumbs up for preventing diabetes.
Another plus is that coffee is naturally calorie-free. Just don't load it up with extra calories from cream, sugar, whipped cream, and/or flavored syrup.
