A new study suggests low-fat dairy products may help bring down the risk of strokes in middle-aged and older adults. Researchers followed the eating habits of close to 75-thousand people ages 45 to 83 for a decade and found that those who consumed the most low-fat dairy were 12 percent less likely to suffer a stroke than those who consumed the least. Low-fat dairy is fortified with vitamin D, which helps lower blood pressure. This is key because high blood pressure has long been recognized as a key risk factor for strokes. The study was published this week in the journal "Stroke."
