Your fridge could help you live longer! Here are foods that'll help your body fight off dangerous diseases, courtesy of Rodale Publishing: If you want to avoid a stroke. Drink 2 glasses of pure orange juice every day - or eat a whole orange. According to a study by Finnish researchers, people who took 200 milligrams of Vitamin C each day - that's the amount in 2 glasses of O.J. - had a lower stroke risk than people who skimped on the Vitamin C. Why? Doctors say Vitamin C helps protect your arteries from damage and lowers your blood pressure - both of which can help prevent a stroke. Don't like orange juice? Then have half a cup of red bell peppers and a cup of broccoli, instead. That'll also get you your daily dose of C. If you want to prevent a heart attack. Drink tea. Researchers at Harvard Medical School found that drinking a cup of black tea each day can reduce your risk of a heart attack by as much as 45 percent! Researchers think it's because the flavanoids in black tea reduce the buildup of fatty deposits in your arteries, which helps prevent heart disease. If you want to ward off diabetes. Whip up a peanut butter sandwich. A study in the Journal Of The American Medical Association found that people who ate peanut butter just once a week had a *16 percent lower risk of developing type 2 diabetes than people who didn't eat any peanut butter. Why? According to Dr. Rui Jiang, who worked on the study, it's because the 'good' fats in peanut butter improve your body's insulin sensitivity. And the more sensitive you are to insulin, the lower your risk of problems.
