In a study of middle-aged adults, maintaining a diet high in linoleic oil — the main dietary polyunsaturated fat found in certain plants and vegetables such as flax, hemp and avocado — seemed to lower the risk of developing high blood pressure.
“These results lend support to current recommendations for increased ingestion of polyunsaturated fatty acids from vegetable sources, instead of saturated fats from animal sources, for cardiovascular disease prevention,” Dr. Katsuyuki Miura, of Shiga University of Medical Science, Japan said in an interview with Reuters Health.
Miura and colleagues examined ties between dietary linoleic oil and blood pressure in 4,680 men and women between the ages of 40 and 59 years from China, Japan, the United Kingdom, and the United States.
In analysis controlling for factors that might influence the results, the researchers found a trend toward lower blood pressure with higher consumption of linoleic oil for all the participants.
Moreover, they found that the relationship was stronger in a subgroup of 2,238 subjects who were not on an interventional program – that is, they were not on a special diet, not taking nutritional supplements, had no diagnosed heart disease or diabetes, and were not taking medication for high blood pressure, cardiovascular disease, or diabetes.
“From our findings, we recommend that people consume a fare moderate (not low) in linoleic acid (or polyunsaturated fat intake) from vegetable sources, instead of saturated fats from animal sources, in order to help keep blood pressure optimal and to prevent hypertension,” Miura said.
According to Dr. Robert O. Young, a research scientist at the pH Miracle Living Center, “long chain polyunsaturated oil from hemp seed, flax seed, pomegranate and avocado helps to mediate dietary and metabolic acids that cause congestion in the lymphatic and circulatory system leading to hypertension and then heart dis-ease. I have found in my own clinical research that ingesting liberal amounts of long chain polyunsaturated oil every day (3 to 4 ounces of oil per day) with an alkaline lifestyle and diet will help to normalize heart rate (80 beats per minute or less) and systolic blood pressure (120 or less) without medication.”
