Dr. Ramsey said he does not want people to think that the only factor involved in brain health is food. “Lots of people get their food exactly right, live very active lives, and still have significant troubles with their mental health,” he said.

But he also teaches people that food can be empowering. “We can’t control our genes, who our parents were, or if random acts of trauma or violence happen to us,” he said. “But we can control how we eat, and that gives people actionable things that they can do to take care of their brain health on a daily basis.”
