Magnesium supplements were found to modestly lower blood pressure—by about 2 points in both systolic and diastolic pressure—in a 2016 analysis of 34 clinical trials. A 2017 analysis of 11 clinical trials reached a similar conclusion. It looked at the effect of magnesium supplements (365 to 450 milligrams a day) on blood pressure in people with diabetes, prediabetes, or insulin resistance. But supplements aren’t necessary to get those levels of magnesium; a healthy diet supplies plenty of the mineral. For the best sources of magnesium, see the chart here.
According to the Centers for Disease Control and Prevention (CDC), an estimated 75 million Americans have high blood pressure. Many risk factors for high blood pressure are out of your control, such as age, family history, gender, and race. But there are also factors you can control, such as exercise and diet. A diet that can help control blood pressure is rich in potassium, magnesium, and fiber and lower in sodium.
Also focus on eating nitrate and nitrite-rich vegetables (not to be confused with the other types of nitrates and nitrites that are found in processed meats) . Nitrates and nitrates from vegetables help to relax and dilate blood vessels throughout your body and increase blood flow. Although it’s a short-term effect, eating more nitrate-rich vegetables like beets, cabbage, leafy greens, and vegetable juices, can reduce blood pressure for a few hours. Recent studies have also shown that those who drank beetroot juice showed an immediate effect on lowering blood pressure. By eating plant-based foods consistently, you’ll see their regular benefits.
Blood pressure medications should only be taken according to your doctor’s instructions. Never take another person’s blood pressure medication and never take an extra or early dose of your own medications unless advised to do so by your doctor. All blood pressure medications can cause dangerously low blood pressure when taken by the wrong person or when taken in excess or too early.
For a study published in the Journal of Nutrition, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University looked at how drinking three daily servings of hibiscus tea over six weeks changed blood pressure in people with pre-hypertension or mild high blood pressure. They found reduction in both systolic and diastolic blood pressure, especially in people with higher systolic blood pressure to start. Hibiscus tea is loaded with antioxidants, including phenols and anthocyanins, which might explain the effect.
Aerobic activity can be an effective way to control high blood pressure. But flexibility and strengthening exercises such as lifting weights are also important parts of an overall fitness plan. You don’t need to spend hours in the gym every day to benefit from aerobic activity. By adding moderate physical activities to your daily routine will also help.
Consuming 4 tablespoons of flaxseed can lower systolic blood pressure in postmenopausal women who have a history of heart disease, a small study found. The seeds are rich in omega-3 fatty acids, which probably explains the effect. Try 2 tablespoons in your oatmeal or yogurt at breakfast, then sprinkle 2 tablespoons over soup or salad later in the day for a tasty crunch. Stock up on these 8 foods that naturally lower blood pressure.
7. Cut down on sodium intake: Processed and packaged food needs to go out of your kitchen, if you want healthy levels of blood pressure. This is because processed food is loaded with added preservatives to increase their shelf life. Also, prepare your food with lesser salt as high intake of salt is linked to risks of high blood pressure and stroke.
In most cases where high blood pressure is diagnosed, the cause remains unclear. One review paper in the International Journal of Hypertension explains that this accounts for around 90% of all hypertension diagnosis and is usually referred to as essential hypertension. Secondary hypertension is diagnosed when a cause can be identified. Potential causes of secondary hypertension may include:
6. Cultivate stress management. You don’t need a meta-analysis of cohort studies to prove stress can raise blood pressure, but they exist. You can’t eliminate stress, but you can minimize its impact. Research shows yoga and meditation create effective strategies to manage stress and blood pressure. If those aren’t your thing, consider other stress-relieving tactics including deep breathing or practicing mindfulness.
