About one in three adults has nonalcoholic fatty liver disease, an often-silent condition closely linked to heart disease.

The largest organ inside your body, your liver performs hundreds of vital functions. It converts food into fuel, processes cholesterol, clears harmful toxins from the blood, and makes proteins that help your blood clot, to name a few. But an alarming number of Americans have a potentially dangerous accumulation of fat inside their livers. Known as nonalcoholic fatty liver disease (NAFLD), this condition is a leading cause of chronic liver disease in the United States—and an increasingly recognized contributor to heart disease.

"NAFLD increases the risk of heart disease independent of other traditional risk factors such as high blood pressure and cholesterol," says Dr. Kathleen Corey, director of the Fatty Liver Disease Clinic at Massachusetts General Hospital. Among people with NAFLD, heart disease is the top killer, accounting for more than 25% of deaths.

People who eat more plant-based proteins from beans, nuts, and grains may have a lower risk of dying from heart disease or any cause, compared with people who eat more animal-based proteins such as meat or eggs. 

Sitting for more than eight hours a day and exercising very little has been linked to a higher risk of heart disease and early death. An hour of moderate-intensity exercise may lessen that risk. 

The science of neurogenesis suggests it's possible to create neurons that improve your memory and thinking skills.

There are many aspects of aging you cannot prevent, but surprisingly, memory trouble is not one of them.

"The dogma for the longest time was that adult brains couldn't generate any new brain cells. You just use what you were born with," says Dr. Amar Sahay, a neuroscientist with Harvard-affiliated Massachusetts General Hospital. "But the reality is that everyone has the capacity to develop new cells that can help enhance cognitive functions."

Lower your dependency on medication by altering your perception of pain.

Everyday pain becomes more constant as you age. It can vary from morning aches to occasional joint flare-ups to recurrent episodes that interfere with your life and overall health.

Yet pain has a valuable role. It alerts your systems to potential injury so you can seek treatment. "Pain is similar to blood pressure, which becomes a problem if the levels become too high," says Dr. Jianren Mao, director of the Harvard-affiliated Massachusetts General Hospital Center for Translational Pain Research. "Only when pain becomes intolerable should you resort to medication or other types of treatment."

There is no conclusive evidence that fish oil supplements reduce inflammation. Diets rich in omega-3 fatty acids are a better bet.

British researchers tested whether behavioral activation therapy alone is as effective as cognitive behavioral therapy. The results were almost identical for both groups, with two-thirds of each group reporting a reduction of depressive symptoms of at least 50%.

Nasal irrigation using a neti pot was more effective than inhaling steam in relieving chronic sinus symptoms in a large randomized study.
