Teenage girls lacking in vitamin D
A University of Maine researcher has found evidence that many girls in Maine are not getting enough vitamin D, either from their diets or sun exposure. Lack of the critical nutrient could lead to health risks later in life, especially for osteoporosis. Vitamin D is necessary for the growth of healthy bones and may be critical in other bodily processes as well.  more

Information for patients: Support your bones with healthy habits
Unearthed skeletons from ancient times testify to the durability of bone long after other bodily tissue turns to dust. Living bone in the body, however, can lose mineral and fracture easily if neglected--a disorder called osteoporosis, or porous bones.

Additional information: Low free testosterone levels linked to Alzheimer’s disease in older men
Older men with lower levels of free, or unbound, testosterone circulating in their bloodstreams could be at higher risk of developing Alzheimer’s disease (AD) than their peers, according to new research. This prospective observational study is believed to be the first to associate low circulating blood levels of free testosterone with AD years before diagnosis.  more

The human side of AD research: Religious orders study and the nun study - Lives of service continue even after death
One way that scientists have tried to unravel the mystery of AD and other complex diseases, like heart disease or cancer, is to compare the characteristics, lifestyles, and disease rates of different groups of people. This approach has often provided clues as to why some people get a disease and others don't. more
