MORE BENEFITS FROM VITAMIN D N
ew research from the Emory/ Georgia Tech Predictive Health Institute suggests that a lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax. The finding adds to evidence showing that insufficient vitamin D leads to impaired vascular health, contributing to high blood pressure and the risk of cardiovascular disease. The body naturally manufac- tures vitamin D when it is exposed to
sunlight. Foods like vitamin-D-fortified milk or cereals and oily fish also are good dietary sources to help provide sufficient amounts of this essential nutrient.
Blueberries Assist Artery Function
A
study conducted by the Agricultural Research Service’s Arkansas Children’s Nutrition Cen- ter and the University of Arkansas for Medical Sciences indicates that eating blueber- ries may help prevent atherosclerosis, or hardening of the arteries. When researchers spiked the diet of 15 lab mice with freeze-dried blueberry powder (comparable to a half-cup of the berries) for 20 weeks, they found that the size of harmful lesions (plaque) measured on two sites in their aortas were 39 and 58 percent less than for 15 mice in a control group.

DON’T TAKE A SEAT
A
multi-ethnic study of 4,757 U.S. adults in a National Health and Nutrition Examination Survey found that those who took the most daily breaks from sitting had, on average, a smaller waist circumference, fewer blood fats and reduced markers for insulin resistance than those who took the fewest breaks. The research- ers also noted increased levels of C-reactive protein in the bodies of sedentary subjects, which is linked to inflammation and many chronic diseases, even in people who regu- larly exercise. To get moving: Stand up to take phone calls and during meetings; walk to visit a colleague, rather than phoning or emailing; use a bathroom on a different floor; centralize trash and recycling bins and office equipment to encour- age short trips during the work day; take the stairs; and park at the far end of the lot.
