**6.4 Nuts**

The outstanding sources of protein and healthy fats are the nuts which aid to improve memory as well as good for both the heart and brain. An omega-3 fatty acid called alpha-linolenic acid (ALA) is found to be high in walnuts. There is an association between intake of diets rich in ALA and omega-3 fatty acids to cardiovascular regulation as it lowers blood pressure and makes arteries cleaner. In 2015 a study was done by the University of California, Los Angeles (UCLA) related higher walnut consumption to improved cognitive test scores.
