1. Olive oil, green tea and leafy greens: These antioxidant superfoods help fight inflammation, which can damage the brain. Before inflammation starts, eating them can protect brain function.
2. Beets, tomatoes and avocados: Studies show these foods help ensure that your brain receives the blood it needs to stay sharp. That promotes neuron growth in the area of the brain associated with learning and memory.
3. Nuts (especially walnuts): They work deep in the brain to fight amyloid plaques. When amyloid accumulates beyond normal levels, its plaques kill neurons while creating inflammation, which kills even more neurons.
