This study was based on a cross-sectional data analysis from the Third National Health and Nutrition Survey, 1988-1994. The aim of the study was to examine if dietary fat intake is associted with cognitive and psychosocial functioning in children.
A high intake of polyunsaturated fatty acids contributed to improved cognition, while a high intake of cholesterol resulted in lower performace. The authors concluded that replacing cholesterol with polyunsaturated fats in the diet may be beneficial. Peanuts contain high amounts of polyunsaturated fats.
