Research we're watching

Many people know what they need to do to keep their hearts healthy. The challenge is making changes (like exercising regularly and eating more fruits and vegetables) and sticking with them. New research suggests monthly meetings with a group of peers who offer support and encouragement can help.

The study included 543 adults with at least one risk factor for heart disease (being overweight, smoking, being physically inactive, or having high blood pressure). Half were randomly assigned to a self-management control group. The others were placed in teams of 10 for the peer-group interventions. Two peer-elected trained leaders headed each group meeting, which involved role-play, brainstorming, and activities to address emotions, diet, and exercise. The groups met for 60 to 90 minutes monthly for one year.

The meditative practice is being used for everything from boosting happiness to treating high blood pressure.

Mindfulness, which trains you to focus your mind on the present moment, is more than a popular meditation technique. It's been shown to help treat depression and anxiety and improve sleep quality. And it's now being studied as a complementary therapy for cancer, stroke, multiple sclerosis, and pain. "We're seeing an exponential increase in doctors embracing mindfulness as a treatment," says Dr. Ronald Siegel, assistant professor of psychology at Harvard Medical School and faculty editor of the Harvard Special Health Report Positive Psychology.

About 1 in 3 people report at least one episode of fainting during their lifetime, so it’s surprising that we don’t see people fainting more often. Fainting is usually harmless, the body’s response to emotional or physical stress. But in some cases, fainting can indicate an underlying problem such as heart abnormalities or seizures. And even when the cause of fainting is not that serious, fainting that leads to a fall can cause injury.

Many people believe that the human tendency to want to act for the greater good is rooted in kindness. But research suggests that altruism may have evolved alongside the impulse to condemn and even chasten those put self-interests first.

Ask the doctor

Q. I find myself getting more and more anxious, but I don't like to take medications. Is there an alternative natural treatment I can try instead?

A. Anxiety is an incredibly common problem. Although there are many FDA-approved medications that have been widely studied and proved effective, studies show that up to 43% of patients with anxiety use alternative medicine to treat it. Among alternative therapies, herbal treatments are widely used both for therapeutic purposes and for comfort.

Ask the doctor

Q. My doctor says the Mediterranean diet is not only good for my health in general, but that it is particularly good for my brain. That got my attention. Anything to it?

A. I think there is. The Mediterranean diet is rich in whole-grain bread, root vegetables, green vegetables, fish, poultry, fruit, and olive oil. It includes relatively little red meat, butter, and other foods rich in saturated fats and trans fats. As is often the case with research into a medical question, not all studies come to the same conclusion. But many studies have found that people who regularly adhere to the Mediterranean diet are less likely to develop Alzheimer's disease. And many studies also find that people with diets rich in saturated fats (including from red meat and processed meat) and trans fats are more likely to develop dementia of some type, along with other brain disease, particularly strokes.
