There are many individual foods and diets that have been researched for their impact on memory and cognitive health.
In terms of a comprehensive diet, the MIND diet has the strongest evidence in support of brain health and cognitive function. This diet is a hybrid of the Mediterranean diet and the DASH diet.
The MIND diet emphasizes the intake of fruits, vegetables, lean proteins, and whole grains while encouraging a low-intake of sodium, processed foods, saturated fats, and dairy.
