Four cups of coffee a day? If the amount of coffee that can help stave off diabetes is also the amount that would make you more nervous than an agoraphobic on his first sky-dive, relax. You don't have to be a full-fledged java junkie to get benefits. Just one cup brings you some protection.
1. Lower stroke risk by 30 percent. Previous studies suggested you needed more than just a cup, but new research suggests that drinking just a cup of any coffee - high-octane or decaf - may do the trick.
2. Lower cancer risk. A 13-year study of Japanese men and women found that drinking a cup or more a day was associated with 50 percent less cancers of the mouth, pharynx and esophagus than in people who didn't drink coffee.
3. More coffee does more: Two to three cups cuts the risk of all deaths by 18 percent in women and 3 percent in men. Three cups drop your risk of Parkinson's and Alzheimer's, and more may help you dodge type II diabetes.
