2. Seaweed
This one’s for you, sushi fans. Even though seaweed is predominantly consumed in Asia, its benefits for the brain are well known. Seaweed is high in omega-3 fatty acids, which are healthy for your brain. Along with iodine, which is helpful for mental performance, seaweed contains magnesium.
Seaweed wraps sushi, for example. Kelp, wakame, nori, and other edible seaweeds can eat dried nori or kombu with cooked beans.
