High blood pressure, or hypertension, is often characterized as the silent killer–and for good reason. Although it affects an estimated one in five North Americans, many people don’t experience any symptoms. As a result, less than one-quarter of sufferers actually receive treatment. Left untreated, however, it can severely damage the cardiovascular system, leading to death from stroke, heart attack or kidney failure.

Most high blood pressure patients are candidates for medications, including ACE inhibitors, beta-blockers, calcium channel blockers and diuretics. However, statistics show that of the 20 to 30 million individuals diagnosed with high blood pressure, less than half stay on their medication for more than one year. Moreover, 60 per cent of those who lower their medication do so because of side-effects. Given this information, the use of nutritional and botanical supplements, along with the adoption of a healthier lifestyle, can be of immense benefit in fighting this hidden killer.

Lifestyle and Dietary Approaches

If you wish to either prevent or treat high blood pressure, changing how you eat, sleep, and respond to stress are very important considerations. In the eight-week DASH trial conducted by the Heart, Lung and Blood Institute in 1997, 70 percent of volunteers who eliminated meat and sugar, decreased unhealthy fat intake, and increased fruit and vegetable consumption decreased blood pressure to below 140/90 mm/Hg compared to just 45 percent of those who only ate more fruits and vegetables.

Individuals with high blood pressure should decrease sodium intake to approximately three grams per day and add at least four daily servings of foods rich in potassium (beans, spinach, melon, potatoes, tomatoes, bananas, avocados). Decreasing sodium intake alone has reduced blood pressure by 8.4 mm/Hg systolic and 4.4 mm/Hg diastolic. Moreover, alcohol intake should be reduced to less than two drinks per day. Research has shown that a shift from five to two drinks daily can decrease blood pressure by 8 mm/Hg systolic and 4.4 mm/Hg diastolic.

A structured exercise program is another important factor. In one study, an average weight reduction of 4.5 kg by individuals who were 10 to 65 per cent overweight led to a significant reduction in systolic blood pressure after just six months. In addition, stopping smoking is a must for anyone diagnosed with hypertension.

Stress Management and Sleep

Those with high blood pressure need to employ stress management and relaxation techniques. This concept was investigated by Dr. D. Shapiro and associates from the department of psychiatry and biobehavioural sciences at the University of California Los Angeles School of Medicine. Individuals with a mild to moderate increase in blood pressure were given blood pressure-lowering medications and then divided at random into two groups. One group performed simple stress management techniques, while the other did not. Remarkably, 55 percent of those who employed stress-reducing strategies were able to remain medication free, compared to only 30 percent in the control group, as found after a one-year follow-up examination.

A good night’s sleep is also important. Researchers from the University of Pavia in Italy found that high blood pressure patients deprived of sleep had significant increases in blood pressures and heart rates, especially during the evening.
