Are low-tar cigarettes less harmful than regular cigarettes?
Not according to the National Cancer Institute. A review of five decades of scientific data showed no evidence that light or low-tar cigarettes have any significant effect on the health risks for smokers. This may be because smokers may smoke more light cigarettes, smoke more of the cigarette or take bigger puffs, all of which increase nicotine intake. Bottom line: There is no “safe” cigarette.
Is there anything I can do to prevent Alzheimer’s disease?
Possibly. A recent study by researchers at Columbia University revealed that regularly participating in leisure activities such as reading a book, visiting a friend or seeing a movie may help reduce the risk for or delay the onset of dementia. The study evaluated 1,772 people ages 65 and older for seven years. Those who were socially and intellectually active on a regular basis had a 38 percent lower risk of developing dementia.
Previous studies have shown a correlation between high education level and job-related achievements and a reduced risk for Alzheimer’s. However, this study is the first to link leisure activities with a reduced risk for people of any education or occupation level. Staying connected and active socially and intellectually may be positive ways to help lower the risk for dementia.
Could I have osteoporosis and not know it?
Yes. According to one of the largest osteoporosis studies to date, almost 20 million American women have thinning bones and don’t know it. This study, which was funded by Merck and Co., makers of an osteoporosis drug, makes it clear why it is vital for postmenopausal women to take steps to prevent osteoporosis. Regular exercise, good nutrition that includes healthy sources of calcium and vitamin D, and medication can help keep bones strong.
Screenings are also important. If you are postmenopausal and have a family history of osteoporosis or are age 65 or older, talk with your doctor about having your bone density measured.
