Which is least likely to reduce your risk of diabetes?
To dodge diabetes, stay lean and exercise. Studies also find a lower risk in people who drink alcoholic beverages in modest amounts (1 or 2 drinks a day for men; half a drink for women), as well as those who eat nuts, whole grains, and unsaturated fats (like the oils in salad dressing). Processed red meats (like bacon, hot dogs, and sausage), trans-fat-laden foods (like French fries, fried chicken, and pie crust), and sweets may raise diabetes risk.
Vitamin D may reduce the risk of all but one of these. Which one?
Studies suggest that vitamin D may reduce the risk of bone loss, gum disease, multiple sclerosis, and colon cancer. Shoot for 400 IU a day (600 IU if you’re over 70). Good sources include multivitamins, calcium+D supplements, milk, and some yogurts, breads, breakfast cereals, margarines, and orange juices. Sunlight is also a good source, but not in the winter north of the line that connects Los Angeles and Atlanta.
Which is least likely to lower your blood pressure?
The DASH study (Dietary Approaches to Stop Hypertension) showed that a lower-fat diet rich in fruits, vegetables, and low-fat dairy foods can lower blood pressure. Researchers aren’t sure whether the potassium, magnesium, calcium, protein, fiber, or other nutrients made the difference.
