The role of dietary polyunsaturated fatty acids and prostaglandins in reducing blood pressure and improving thrombogenic indices.
Evidence linking dietary fats to blood pressure and thrombogenic indices is reviewed. Results of dietary studies performed at Beltsville, Maryland, have demonstrated that under controlled dietary conditions, i.e., when total fat intake is maintained at 25% fat calories with a P/S ratio of 1, at either a fixed or free-choice salt intake and where the body weight is maintained relatively constant, blood pressure can be lowered and platelet aggregation indices can be improved in men and women in the 40-60 age group. Results of a pilot epidemiologic study of farmers aged 40-45 in Finland and Italy generally confirm the experimental nutrition studies reported above. A possible explanation of these results based on the conversion of linoleic acid to prostaglandins as well as the physiological actions of prostaglandins is discussed.
