Blood pressure and why it matters

Blood travels from the heart via arteries to smaller arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. Blood pressure refers to the force pushing outward on the walls of your arteries. The more forcefully that the blood pumps, the more that the arteries are required to stretch to allow the blood to easily flow. Over time, if that force is too great, the tissue that makes up the arterial walls can become stressed and damaged.

This can lead a wide range of problems. For example, it makes arteries more vulnerable to infiltration and accumulation of cholesterol. It also can destabilize any existing arterial plaques which increases the risk of them rupturing and inducing heart attacks.

So, high blood pressure is a really big deal. High blood pressure is often characterized as a “silent killer” because it can cause permanent damage throughout the body without any obvious symptoms. Tragically, by the time the problem becomes obvious, it is sometimes too late to reverse the damage.

About 70 million adults in the US have hypertension – that’s 1 in every 3! and only around 52% of people with hypertension have it under control. It is also likely that many are walking around with the condition who don’t even know they have it.

Healthy blood pressure levels are an indicator of how clear the body’s arteries are. When blood pressure levels get out of balance, they can signal a potential heart attack or stroke. High blood pressure levels are often caused by atherosclerosis, also called hardening of the arteries, which occurs when oxidized particles of LDL cholesterol stick to the walls of the arteries. Eventually these particles build up and form plaque, narrowing the blood vessels and putting a heavier workload on the heart as it pumps oxygenated blood to the entire body.

One of the specific compounds in Extra Virgin Olive Oil that directly combats this build-up is called oleuropein. Oleuropein has been found by scientists to prevent the LDL cholesterol from oxidizing and sticking to the arterial walls.

Saturated fat diets are associated with higher blood pressure but there have been few good studies on whether the reverse is true; can unsaturated fats lower blood pressure and are some unsaturated fats better than others?

A well-designed study published by researchers from the University of Naples, Italy fed 23 subjects a diet rich either in monounsaturated fatty acids (MUFA) such as are found in high quality Extra Virgin Olive Oil or polyunsaturated fatty acids (PUFA) such as are found in sunflower oil for one year.

At 26.6% of calories from fat the experimental diet was also low in total fat. The study was double blinded with neither subjects nor researchers aware of which oil was being used. Subjects were told to cook with given oil and men were told to add 40g and women to add 30g of oil after cooking. The study participants experienced no change in weight during the year.

In their words, “the main result of our investigation was a straightforward reduction in antihypertensive tablet consumption when patients were given Extra Virgin Olive Oil, whereas drug consumption was only mildly affected by sunflower oil.”

The need for common blood pressure drugs such as atenolol, HCTZ, and nifedipine was cut in half after just 4 months on the olive oil diet whereas drug consumption was only mildly affected by sunflower oil. Cholesterol and triglyceride levels were also slightly lower while on the olive oil diet. There are as many as 5 mg of antioxidant polyphenols (absent in sunflower oil) in every 10 grams of olive oil. Antioxidants also reduce nitric acid levels, a substance in the body known to raise blood pressure.

Readers with concerns over high blood pressure should consult their doctor.
