Foods That Are Surprisingly Great for Your Brainpower

3. Natto: The Fermented Secret to Sharp Thinking

Natto, a traditional Japanese fermented soybean dish, is one of the best natural sources of vitamin K2, which supports brain function by helping to protect nerve cells from damage. It’s also loaded with probiotics, which improve gut health—a key player in mood and cognitive function. Though its strong flavor and sticky texture may be an acquired taste, natto is a powerful ally for long-term brain health.

4. Tart Cherries: Sleep and Memory Enhancers

Tart cherries are rich in melatonin, a hormone crucial for sleep regulation. Quality sleep is essential for cognitive function, memory consolidation, and mental clarity. These small but mighty fruits also contain anthocyanins and quercetin, which help reduce inflammation and oxidative stress in the brain. Enjoy them as a juice, dried snack, or fresh when in season.
