Consistent exercise is associated with a lower risk of dying from colon cancer, according to a new study led by researchers at the Siteman Cancer Center at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis. The study is among the first to show that physical activity can make the disease less deadly. Check the end of this report for an audio summary of the study results.

Addiction researchers at Washington University School of Medicine in St. Louis have found that a risk for alcoholism also may put individuals at risk for obesity. The results of the study were published in the Archives of General Psychiatry. Included within this report is a audio interview with the lead researcher.

Maybe age really is just a number. How young or old someone feels has a huge influence on their health and how other people view them. An article published in Perspectives on Psychological Science, a journal of the Association for Psychological Science, reviews the research and suggests that feeling young can actually make you look young – and have the health of a younger person, too.

Menthol cigarettes may be harder to quit, particularly for some teens and African-Americans, who have the highest menthol cigarette use, according to a study by a team of researchers. Recent studies have consistently found that racial/ethnic minority smokers of menthol cigarettes have a lower quit rate than comparable smokers of regular cigarettes, particularly among younger smokers.

CSF researchers have identified an existing medication that restores key elements of the immune system that, when out of balance, lead to a steady decline in immunity and health as people age. The team found that extremely low doses of the drug lenalidomide can stimulate the body’s immune-cell protein factories, which decrease production during aging, and rebalance the levels of several key cytokines – immune proteins that either attack viruses and bacteria or cause inflammation that leads to an overall decline in health.
