High blood pressure is a major risk factor for a heart attack or stroke. In fact, it is generally regarded as the most significant risk factor for a stroke. Here are four natural ways to reduce blood pressure: Why it works: The decrease in blood pressure is due to the chemical formation of nitrite from the dietary nitrates in the juice. Once in the general circulation, nitrite can be converted to nitric oxide (NO) by the cells that line blood vessels. NO is a powerful dilator of blood vessels, resulting in lower blood pressure. Why it works: All of the beneficial effects of garlic are attributed to its sulfur-containing compounds: allicin, diallyl disulfide, diallyl trisulfide, and others. Allicin is mainly responsible for the pungent odor of garlic. It is formed by the action of the enzyme alliinase on the compound alliin. The enzyme is activated by heat, oxygen, or water. This accounts for the fact that cooked garlic, odorless supplements, “aged garlic preparations,” and garlic oil products produce neither as strong an odor as raw garlic nor nearly as powerful medicinal effects as raw fresh garlic. At the end of the study, the black tea–drinking group had an average reduction of 2 to 3 points in their systolic (the top number in a blood pressure reading) level, and about two points in their diastolic (the bottom number) level. Although this doesn’t sound like much, the researchers said it’s enough to reduce the risk of heart disease and stroke by 7 to 10%. Why it works: It’s believed that black tea’s hypertension benefits may be due to the fact that the beverage improves the function of the endothelial cells that line the interior of blood vessels and affect blood pressure. Other research suggests that flavonoids in black tea can improve the tone of blood vessels, helping them channel blood more efficiently. This is key, because research shows many adults don’t get the recommended dietary allowance of at least 320 mg of magnesium for women and 420 mg for men, and that for every 100 mg increase in magnesium intake, the risk of stroke is reduced by about 9 percent. Why it works: Magnesium helps dilate blood vessels and prevents spasm in your heart muscle and blood vessel walls. It also dissolves blood clots. All of these aid optimal heart and blood vessel function and can help to lower blood pressure.
