NEW YORK (Reuters Health) Sept 05 - The results of a study published in the August issue of Hypertension suggest that there is an inverse relationship between dietary linoleic acid and blood pressure. This relationship is appears stronger in patients who are not receiving a dietary or medical intervention.
"Findings from observational and interventional studies on the relationship of dietary linoleic acid, the main dietary polyunsaturated fatty acid, with blood pressure have been inconsistent," Dr. Katsuyuki Miura, of Shiga University of Medical Science, Japan, and colleagues write.
Dr. Miura's group used data from the International Study of Macro-Micronutrients and Blood Pressure to examine the association between dietary linoleic acid and blood pressure in 4680 men and women between the ages of 40 and 59 years from 17 population samples in China, Japan, United Kingdom, and United States.
Data on nutrient intake were obtained from four in-depth 24-hour dietary recalls per person and two timed 24-hour urine collections per person. Systolic and diastolic blood pressures were measured eight times at four visits.
