While the underlying cause of primary (essential) hypertension is not known, what has been confirmed over many studies by researchers is that high blood pressure is a significant risk factor for heart disease and stroke.
A review by the American Heart Association concluded that fish and fish oils help prevent cardiovascular disease including fatal and non-fatal heart attacks, strokes, sudden cardiac death, and coronary artery disease (angina).
Fish and fish oils contain long-chain polyunsaturated omega-3 fatty acids, more specifically, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The average American diet contains only about 100-200 mg/day of EPA and DHA. The diet also contains about 1.4 grams/day of alpha- linolenic acid mainly from canola and soybean oils.
But until recently there was not enough evidence for the mainstream medical community to recommend taking fish oil for blood pressure reduction.
That has however changed in light of findings reported in a 1993 meta-analysis of 31 placebo-controlled trials that studied fish oil for blood pressure control. In all, the studies were carried out on 1356 subjects, and examined the effect of omega-3 fatty acids in fish oil on blood pressure.
Analysis of the collective data suggested a strong correlation between both eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and a blood pressure response. The blood pressure of hypertensive subjects dropped in direct proportion to their daily intake of fish oil which was rich in omega 3 fatty acids.
It further appeared that this effect of fish oil on blood pressure was more manifest in those with high blood pressure (hypertensives) high blood cholesterol levels and atherosclerotic disease, rather than subjects with normal blood pressure.
Researchers at the University of Western Australia have also published results from a study of 63 men and postmenopausal women who were overweight and being treated for high blood pressure. They showed that weight loss combined with daily fish oil consumption is very effective in lowering blood pressure, triglyceride levels and increasing ‘good’ cholesterol.
The researchers concluded that this association was not a chance occurrence, and that a combination of weight loss and daily fish consumption significantly reduces the risk of cardiovascular disease among obese patients with high blood pressure.
Omega 3 fats, the kind you see in good fish oil, has been shown to reverse heart disease and have many other benefits. They boost immune function, fight degenerative disease, help increase fertility, improve mental health and promote healthy skin.
Fish oil is the best source of critical long-chain omega fatty acids like DHA and EPA, yet the most likely to be contaminated with PCBs, DDT and dioxin, along with heavy metals like mercury.
Taking fish oil capsules avoids these toxins. Top brands use oil from fish caught in the cleanest and coldest waters, preferably those far from commercial shipping lines and industrialized countries where the highest risk of water contamination by wastes exists. Making fish oil capsules even safer is the practice of molecular distillation.
