If you’re eating more fruits and vegetables, you’re already taking a positive step toward reducing salt and enhancing potassium intake. Sodium can be found in abundance in processed foods – anything that comes in a package, can, or especially from a fast food restaurant. If you’re over 50, or at higher risk, aim for no more than 1,500 mg/day. Check your food labels for sodium content. If you see that a food has more than 400-500 mg in a serving, see if there’s a lower-sodium option.
There are more worrisome facts about medications, notes Dr. Fruge. Drug treatment frequently has annoying and sometimes dangerous side effects, and never cures the disease. All too often, blood pressure problems grow progressively worse despite the use of medications. That’s deeply troubling because hypertension is a major risk factor for heart attacks, strokes, heart failure, cardiac arrhythmia, and premature death.
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.
Certain groups of people—the elderly, African Americans, and those with a family history of high blood pressure—are more likely than others to have blood pressure that's particularly salt-sensitive. But because there's no way to tell whether any one individual is at risk, everyone should consume less sodium, says Eva Obarzanek, PhD, a research nutritionist at the National Heart, Lung, and Blood Institute.
In a hot tub, as the water comes through the pipes, it has a degree of force. This force is caused by the action of the pump, which puts energy into the circulating system and forces the water through the pipes. When the pump is off, there still may be water in the pipes, but there is no force. The degree of force in the system when the pump is on can be gauged in several ways, such as by putting your hand in front of a “jet.” Another way would be to have a device to measure the amount of force that the water exerts against the walls of the pipes as it circulates. Such a device might yield a numerical measurement of the force, or pressure, of the water within the pipes.
We asked clinicians from Beth Israel Deaconess Medical Center’s CardioVascular Institute how they advise their patients to keep blood pressure under control. While medication is the right solution for some people, the good news is that lifestyle changes can help reduce — and in some cases replace — the amount of medication needed. It’s a good place to start.
Eighty million U.S. adults, or one in three, have hypertension (1). Another one in three have prehypertension, defined as blood pressure in the range of 120–139/80–89 mmHg. In addition to costing $48.6 billion annually, hypertension is a major risk factor for cardiovascular disease, congestive heart failure, chronic renal failure, and stroke (1). Even prehypertension increases the risk of death from CVD (2). Because of its severity, hypertension requires immediate treatment, but prescription drugs may not be the answer.
Blood pressure is written as two numbers, such as 112/78 mm Hg. The top, systolic, number is the pressure when the heart beats. The bottom, diastolic, number is the pressure when the heart rests between beats. Normal blood pressure is below 120/80 mm Hg. If you’re an adult and your systolic pressure is 120 to 139, or your diastolic pressure is 80 to 89 (or both), you have pre-hypertension. High blood pressure is a pressure of 140 systolic or higher and/or 90 diastolic or higher that stays high over time.
“This does not mean I want them exercising so hard that they pass out, but I want them to be challenged, even if it means taking a break if they have to,” he said. “For some people, that may mean nothing more than a gentle walk with periodic breaks, but as the weeks go on they need to challenge themselves to get rid of those breaks, little by little.”
Even if you don’t keep a salt shaker on the table, you may have too much sodium in your diet. Processed foods -- especially canned soups, salad dressings, snack mixes, and fast food -- are a large contributor of sodium to your diet. Read food labels and choose low-sodium options when possible. Aim to consume less than 2,300 milligrams per day, and less than 1,500 milligrams if you’ve already been diagnosed with hypertension.
A 2013 study published in “Hypertension” concluded that flaxseed lowers blood pressure in hypertensive patients. It is a great home remedy for high blood pressure. More than 100 patients diagnosed with peripheral artery disease, a condition associated with high blood pressure, were assigned to a flaxseed group or a placebo group. The former ate 30 grams of flaxseed every day for 6 months.
