Effect of a monounsaturated diet vs. a polyunsaturated fatty acid-enriched diet on blood pressure in normotensive women and men.
The effect on blood pressure of monounsaturated and (n-6)polyunsaturated fatty acids was studied under strict dietary control in normotensive subjects. For 17 days 31 women and 27 men received a control diet providing 19.3% of energy as saturated fat. Then subjects were randomized over two test diets: one diet provided 15.1% of energy from monounsaturated and 7.9% from polyunsaturated fatty acids ('mono diet'), and the other diet provided 10.8% from monounsaturated and 12.7% from polyunsaturated fatty acids ('poly diet'). Saturated fat intake was now 12.8% on both diets. Mean blood pressure at the end of the control period was 116/69 mmHg for the mono group and 117/73 mmHg for the poly group. After 5 weeks on the test diet, blood pressure was 115/67 mmHg for the mono group and 117/72 mmHg for the poly group (difference in changes between the two diet groups was not significant). These findings suggest that at a high fat intake, linoleic acid, when providing more than 7.9% of energy intake, does not influence blood pressure relative to oleic acid in normotensive women and men.
