Coffee
Coffee and tea may help protect your heart by warding off type 2 diabetes. Studies show that people who drink 3-4 cups a day may cut their risk by 25% — and even decaffeinated coffee works. Caution is due, however, for those who already have diabetes or hypertension; caffeine can complicate these conditions.
Tip: Choose black coffee or a non-fat latte to limit fat and calories.
There is something binary about this advise. It seems to be saying drink the coffee for your heart and it will help prevent diabetes. On the other hand, once you've gotten diabetes, you've got to quit drinking coffee for your heart.
Caffeine is highly addicting and I am having a hard time kicking it. I have stopped buying Diet Pepsi and keeping it in the house. I still buy the stuff at restaurants, unfortunately...
