Should you take “senior” multivitamins?

There is little scientific proof that multivitamins or special “senior” vitamin formulas helps you live longer, feel better, or avoid disease. Spending money on fresh fruits and vegetables is a wiser and healthier investment.

Back to school

Active aging involves more than moving your body. You also need to move your brain. "When you exercise, you engage your muscles to help improve overall health," says Dr. Ipsit Vahia, director of geriatric outpatient services for Harvard-affiliated McLean Hospital. "The same concept applies to the brain. You need to exercise it with new challenges to keep it healthy."

A fun way to do this is to sharpen your No. 2 pencils and go back to school. "New brain cell growth can happen even late into adulthood," says Dr. Vahia. "The process of learning and acquiring new information and experiences, like through structured classes, can stimulate that process."

Dietary nitrate may lower risk of glaucoma

Eating 10 servings of green leafy vegetables per week, or about 1.5 cups per day, may lower a person’s risk for primary open-angle glaucoma by 20% to 30%. These foods are rich in nitrate, which can help reduce eye pressure and improve blood flow to the optic nerve.

Are you taking more than one drug? Are you taking a few different types of medications? Are you seeing several different doctors? If so, you may be at increased risk for drug interactions, which occur when a drug, a supplement, or even a food affects the way your body processes a medication. Such interactions can make a drug more powerful—so that a standard dose becomes an overdose—or can render it less potent or altogether ineffective.

We've known for a long time that being overweight is a major risk factor for developing type 2 diabetes. But only in the last 20 years have researchers determined that metabolism and immune responses are linked and that chronic inflammation plays an important role in the development of obesity, diabetes, and related metabolic diseases. "Inflammation is not only associated with obesity, diabetes, and cardiovascular disease, but also precedes and predicts these conditions," says Dr. Allison Goldfine, head of the Clinical Research section at Harvard-affiliated Joslin Diabetes Center.

A team of German researchers analyzed data from more than 90,000 women enrolled in the Women's Health Initiative (WHI), who were ages 50 to 79 when they entered the study.
