Dietary fat intake and blood pressure in 10 to 19 years adolescents in the United Kingdom

Studies supported that total fat intake was associated with increased risks of hypertension, but as a subgroup of fat, n-3 polyunsaturated fatty acid (PUFA) intake had association with reduced risk of hypertension(1). General information, anthropometric and blood pressure (BP) were collected, and dietary data was assessed from a four-day food record.
