One of the most powerful things you can take for your brain

Nearly all Americans are failing to get one of the most potent things they can take for brain health. The good news is that you don’t need to spend hundreds of dollars on supplements to get it. What’s this seemingly magic compound? It’s fiber. That’s it.

And you can meet your fiber goals through simple measures, such as eating an extra serving of veggies or beans, says Dr. Trisha Pasricha, a physician at Beth Israel Deaconess Medical Center, an assistant professor of medicine at Harvard Medical School and The Washington Post’s Ask a Doctor columnist.
