Exercise May Stave Off Early Death for Older Adults T STRESS COULD IMPACT TASTE reating exercise as medicine might go a long way in reducing the chances of earlier death in older adults (women in particular), according to a study by researchers at the Queensland University of Technology in Australia. Analyzing data from five years of research, researchers found out that moderate to highintensity activities are essential to reducing the risk of death in women 50 years and older. Researchers recommend that, in addition to conventional treatments, health professionals should also prescribe customized and regimented exercise programs to older adults. According to Debra Anderson, one of the study’s researchers, older adults should be doing at least 30 to 45 minutes of moderate to high-intensity exercise, five times a week. Do you offer tailored fitness programs to your older guests? Are your staff members welltrained to understand your older guests’ unique health needs and risks? N ew research published in Neuroscience Letters suggests that, under conditions of stress, hormones called glucocorticoids (GC) interact with receptor sites on taste cells, which in the process, affect our sense of taste. The study’s lead author, Dr. Rockwell Parker of the Monell Chemical Sciences Center in Philadelphia, Pennsylvania, thinks that the results may help explain “stress-eating.” According to Dr. Parker, sweet taste, in particular, could be affected by stress. The study found that, when under stress, GC hormones affect the body by activating specialized GC receptors. The highest concentrations of GC receptors were found in Tas1r3 taste cells, which are sensitive to sweet and umami tastes. Taste receptors, however, are found all over the body—including the gut and pancreas. As a result, stress might affect many stages of the ingestion process, including metabolism and appetite.
