3. Eat mind-healthy foods
Studies have documented particular diets that promote brain health. You don't have to switch to a Mediterranean or DASH diet to promote brain health (although these diets do lower your risk of Parkinson's or Alzheimer's), just incorporate foods from these diets known for brain benefits: chicken and turkey, fatty fish, legumes, whole grains, leafy greens, olive oil, and red wine.
4. Cut the bad stuff
If you eat the good stuff without cutting bad foods, the benefits will be canceled out. Reduce your intake of red meat, sugar, processed foods, salt, and cheese.
