MORE REASONS TO SEE A DENTIST REGULARLY
Data collected from nearly 7,000 participants suggests that women who receive regular dental care reduce their risk of heart attacks, strokes and other cardiovascular problems by at least one-third. The findings, published in the journal Health Economics, compared people who visited the dentist during the last two years with those who did not.

50 percent lower risk of developing the most common forms of breast cancer than postmenopausal women who have never had such symptoms, according to a new study by the Fred Hutchinson Cancer Research Center. Commenting on the study, breast cancer Oncologist
Dr. Stefan Gluck, of the University of Miami’s Sylvester Comprehensive Cancer Center, observes that the reduction in risk evidently linked to a natural decrease in estrogen is substantial. “At age 50, a woman has

Dispose of Body Fat Whole Grains
Human Nutrition Research Center on Aging, at Tufts University, adults who ate three servings of whole grains a day while also eating less than one serving a day of commercially enriched flour products had less of a type of fat tissue that is thought to play a key role in triggering diseases. The fat is known as visceral adipose tissue, or VAT, which surrounds internal organs. The researchers examined 2,834 participants, ages 32 to 83,

and VAT volume was approximately 10 percent lower in the healthy eating group. However, lead study author Nicola McKeown, Ph.D., explains that, “Whole grain consumption did not appear to improve VAT volume if refined grain intake exceeded four or more servings per day. This result infers that it is important to make substitutions in the diet, rather than simply adding whole grain foods. For example, choosing to cook with brown rice instead of white, or making a sandwich with whole grain bread instead of white bread.”

dermatologists to smooth wrinkles; now research reveals why the treatments work. Susanna Dams, Ph.D., describes the process in her biomedical engineering doctoral dissertation for Eindhoven University of Technology. The principle of laser therapy involves introducing heat under the skin with precision. Dams first tested the effect
of heat on cell cultures by giving them heat shocks of 113 degrees and 140 degrees Fahrenheit without a laser, to exclude possible effects generated by the laser light. Next, she conducted similar tests on pieces of excised human skin. Finally, she heated pieces of skin with a laser. The results showed that
the heat shocks led to increased production of collagen—a crucial factor in natural skin rejuvenation that declines after the age of 25, causing wrinkles to form and skin to sag. The best rejuvenation effect in Dams’ research resulted from a heat shock of 113 degrees lasting eight to 10 seconds; her work further showed that just two seconds at the higher temperature damages skin cells.
