People who ate healthy plant-based foods had a 10% reduction in stroke risk, compared with people who ate unhealthy plant-based foods, according to a Harvard study published online March 10, 2021, by the journal Neurology.

You have the power to reduce certain risk factors for the disease.

We've come a long way in our understanding and treatment of age-related macular degeneration (AMD), the leading cause of vision loss for people ages 50 or older in the United States. We've learned that certain genes and lifestyle factors increase the risk for developing AMD, and discovered treatments that often slow the disease's progression.

Yet for all our advances, we still don't have a guaranteed way to prevent AMD. You are at greater risk if one of your parents had the condition. "One needs to be concerned, but it doesn't mean you're destined to get it. It's a complex disease, and it takes a combination of factors for it to develop," says Dr. Joan W. Miller, chief of ophthalmology at Harvard-affiliated ­Massachusetts Eye and Ear and ophthal­mology chair at Harvard Medical School.

Can you be "fat and fit" — that is, overweight but still healthy because of regular exercise? There is no simple answer. But one study says that activity does not entirely reverse the effects weight has on heart health. The findings were published online Jan. 26, 2021, by the European Journal of Preventive Cardiology.

The study involved more than 527,000 adults, almost 70% of whom were men. People were placed into three groups based on their body mass index (BMI): normal, overweight, and obese. They also were grouped by activity level: regularly active (the minimum requirement from the World Health Organization, or WHO); insufficiently active (less than the WHO minimum, but some moderate to vigorous physical activity every week), and no exercise.
