* The finding that decaffeinated coffee is only half as effective is probably due to the stripping of much of the goodness of the coffee in order to remove the caffeine. There is a good reason why decaf doesn’t taste as good.

Also, if you’re interested, I give some tips that I’ve learned as to how to make the healthiest, best tasting coffee possible, at home in comment #2 in this article: Cup of coffee a day can keep Alzheimer’s away, say scientists

Want a drug that could lower your risk of diabetes, Parkinson’s disease, and colon cancer? That could lift your mood and treat headaches? That could lower your risk of cavities?

If it sounds too good to be true, think again.

Coffee, the much maligned but undoubtedly beloved beverage, just made headlines for possibly cutting the risk of the latest disease epidemic, type 2 diabetes. And the real news seems to be that the more you drink, the better.

Reducing Disease Risk

After analyzing data on 126,000 people for as long as 18 years, Harvard researchers calculate that compared with not partaking in America’s favorite morning drink, downing one to three cups of caffeinated coffee daily can reduce diabetes risk by single digits. But having six cups or more each day slashed men’s risk by 54% and women’s by 30% over java avoiders. …

In recent decades, some 19,000 studies have been done…

“Coffee is loaded with antioxidants, including a group of compounds called quinines that when administered to lab rats, increases their insulin sensitivity” he tells WebMD. This increased sensitivity improves the body’s response to insulin.

That may explain why in that new Harvard study, those drinking decaf coffee but not tea beverages also showed a reduced diabetes risk, though it was half as much as those drinking caffeinated coffee.*

“We don’t know exactly why coffee is beneficial for diabetes,” lead researcher Frank Hu, MD, tells WebMD. “It is possible that both caffeine and other compounds play important roles. Coffee has large amounts of antioxidants such as chlorogenic acid and tocopherols, and minerals such as magnesium. All these components have been shown to improve insulin sensitivity and glucose metabolism.”

Meanwhile, Italian researchers credit another compound called trigonelline, which gives coffee its aroma and bitter taste, for having both antibacterial and anti-adhesive properties to help prevent dental cavities from forming.
