3. Walnuts
Most nuts provide a serious punch of plant-based proteins and healthy fats to massage your arteries over time, but walnuts are particularly known for their cognitive boost. Alpha-linolenic acid (known as ALA) is one of the main Omega-3 fatty acids found in walnuts and is known for its cardiovascular effects as well as its ability to feed your mind. In fact, a recent study issued by the University of California Los Angeles linked higher walnut consumption to improved cognitive test scores.
4. Butternut Squash
Any food that is orange is good for both heart and brain health, mostly due to the antioxidants found in carotenoids (the orange pigment). Since butternut squash is low-calorie but high in fiber, it’s also a weight-loss ally. This is especially important since being overweight and obese is considered a risk factor for Alzheimer’s and cognitive decline.
