7. Salmon and tuna
You may make it a habit to avoid fatty foods, but when it comes to fish, fat is a good thing. Fish such as salmon and tuna are rich in omega-3 fatty acids, which are associated with many positive health outcomes, including for the brain. In particular, these healthy fats have been tied to lower levels of beta-amyloid in the blood. This damaging protein forms clumps in the brain that often lead to Alzheimer’s disease.
Daily recommended intake: Aim for at least two servings of low-mercury fish such as salmon and light tuna per week.
An apple a day may keep the doctor away, but a bunch of berries keeps mental decline at bay. Berries are one of the best brain foods because they’re packed with flavonoids. Not only do these natural pigments make berries colorful, but they also improve brain function, particularly when it comes to memory.
Daily recommended intake: Eating at least two servings (half a cup each) of berries per week has been shown to slow memory decline by as much as two-and-a-half years.
