For centuries people have been puzzled by the inevitability of human aging. For most of the second half of the twentieth century, aging remained a mystery, or an unsolved biological problem. At the end of the 20th century, a remarkable scientific discovery emerged.
Age-related macular degeneration (AMD) and its associated vision loss may be connected to the quality of carbohydrates an individual consumes. In a study published in the July issue of the American Journal of Clinical Nutrition, Allen Taylor, PhD, director of the Laboratory for Nutrition and Vision Research at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University, and colleagues confirmed earlier findings linking dietary glycemic index with the risk of developing AMD.
Individuals age 49 and older with cataract and those age 49 to 74 years with age-related macular degeneration appear to have higher mortality rates over an 11-year period than those without such visual impairments, according to a report in the July issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Lesions commonly seen on MRI in the brains of older patients may be a sign of potentially more extensive injury to the brain tissue, according to a recent study conducted by researchers at the Duke University Medical Center, in Durham, N.C.
Researchers at Tufts University report a temporal relationship between nationwide folic acid fortification and an increase in rates of colorectal cancer. Their analysis and resulting hypothesis adds to ongoing debate and suggests further research on total population effects of fortification.
A new analysis of data from a large national study found that people who took a 200 microgram selenium supplement each day for almost eight years had an increased risk of developing type 2 diabetes than those who took a placebo or dummy pill.
Recent clinical studies have proven that the photo-stabilized Helioplex technology found in Neutrogena(R) Ultra Sheer Sunblock SPF 70, is the best sun protection available in the United States today.
Although a number of studies have suggested that regular exercise reduces inflammation ? a condition that is predictive of cardiovascular and other diseases, such as diabetes ? it is still not clear whether there is a definitive link. And if such a link exists, the nature of the relationship is by no means fully understood.
Among older persons without manifest cognitive impairment, difficulty in identifying odors such as lemon, banana, soap and cinnamon predicts subsequent development of Mild Cognitive Impairment MCI which is often a precursor to Alzheimer’s disease.
Research is increasingly showing that aging doesn’t automatically result in a steady erosion of brain cells. Rather, older adults who work their brains can develop new connections between brain cells.
