In this brief monologue, board‑certified neurologist Dr. David Perlmutter debunks the notion that there is a single, best action for brain health. He argues that brain health is a holistic system built on multiple essential pillars: restorative sleep, regular physical exercise, and a colorful, primarily plant‑based diet (with optional meat). Neglecting any one pillar creates a weak link that undermines overall brain function, so a balanced approach across all three is required.

What's the one best thing you could do for brain health? Hi, I'm Dr. David Perlmutter. I'm a board-certified neurologist, and trick question, there isn't just one best thing. You shouldn't be relying on just getting enough exercise while you don't pay attention to the type of food that you eat. You really have to think about all the pillars, including restorative sleep, certainly exercise, and certainly the food that you eat. Colorful, plant-based diet. You can have meat if you think that's going to be a part of your diet, But all of these things conspire to bring about brain health, and you can't really have a weak link in the chain.
