A study found that a mixture of healthy living, consisting of physical activity, non-smoking, and a high-quality diet, could reduce the risk of Alzheimer's disease.

Researchers from Rush University Medical Center examined data for nearly 3,000 people, from two longitudinal studies, managed by the National Institute on Aging, according to the British Daily Mail website.

They found that people who followed a healthy lifestyle had a 60% lower chance of developing Alzheimer's disease.

The researchers also pointed out the need to refrain from consuming alcoholic beverages and perform cognitive activities such as chess, which maintain the activity of the mind.
