Nutrition is another key piece, though perhaps not as key as walking. According to the original study mentioned, researchers need more and consistent information on the most beneficial dietary factors and how different foods affect different biomarkers (the latter includes certain proteins, blood pressure and tumors, for example).
Additionally, it’s important to note that most current research looks at a combination of factors, not diet alone. “Pairing [walking] with nutrient-rich foods … gives the brain the building blocks it needs to stay resilient,” Zubkov said.
With that said, knowledge about brain-healthy foods does exist. The study found positive results with the MIND-diet, or the Mediterranean-DASH Intervention for Neurodegenerative Delay. It’s a hybrid of the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) antihypertensive diet.
The MIND-diet includes whole grains; dark, leafy, green vegetables; nuts; olive oil; berries; and even red wine, among other foods and beverages.
Zubkov recommended a few key nutrients: omega-3s, antioxidants and polyphenols. More specifically, he encouraged people to eat fatty fish, walnuts, leafy greens and berries, and to drink green tea.
Are there other ways to generate BDNF?
