Anyone who has a close relative with Alzheimer’s shares the same worry: Am I next?

However, a growing body of research indicates that our lifestyles — particularly what we eat and whether we’re obese — play a greater role than our genes in determining our brain health as we age.

“For years, scientists thought that Alzheimer’s was primarily genetic,” said Gary Wenk, professor of neuroscience at Ohio State University. “We now believe that, while there’s a genetic component, Alzheimer’s is primarily a lifestyle disease.”
