Moreover, caffeine can cause short-term spike on your blood pressure. Read here to know how many cups of tea or coffee you should have in a day in order to keep your blood pressure under control.
“We have many people with hypertension who come to Pritikin,” says Pritikin’s Associate Medical Director Danine Fruge, MD, “and within three days, many have blood pressures that have dropped so low that we need to reduce their medications or take them off their pills altogether. Yes, just three days. That’s how quickly and powerfully our bodies respond to healthy food, exercise, and other lifestyle changes.”
Again, foods that lower blood pressure are usually high in potassium and similar nutrients. Famously rich in blood pressure-lowering potassium, one banana contains about 420 milligrams, or 11 percent of the 4,700 milligrams the American Heart Association recommends people consume daily. Surprisingly, however, many veggies are actually higher in potassium than these popular fruits. A cup of Swiss chard boasts 960 milligrams, a cup of cooked white beans has nearly 1,200 milligrams, and a whole avocado has 975 milligrams.
Sprinkling ground flaxseed over your meals can make a big impact on your blood pressure readings. In a 2013 study published in the journal Hypertension, participants with high blood pressure and peripheral artery disease ate 30 grams (about an ounce) of milled flaxseed daily. After six months, their systolic blood pressure (the top number) went down by 15 mm Hg, on average, and their diastolic blood pressure (the bottom number) dropped by 7 mm Hg.
Regular visits with your doctor are also key to controlling your blood pressure. If your blood pressure is well-controlled, check with your doctor about how often you need to check it. Your doctor may suggest checking it daily or less often. If you're making any changes in your medications or other treatments, your doctor may recommend you check your blood pressure starting two weeks after treatment changes and a week before your next appointment.
Results from SPRINT suggest that if you’re similar to the SPRINT participants, you may experience additional benefits by aiming for a systolic BP close to 120. If you’re considering this, be sure to read my article explaining SPRINT and related research, so that you’ll have a clear understanding of how likely you are to benefit (at best, an estimated 1 in 27 chance based on the research) and what are the risks and burdens.

The DASH (Dietary Approaches to Stop Hypertension) diet has been proven best for controlling blood pressure, according to the American Heart Association. People who follow the diet eat 2,000 calories a day of fruits, vegetables, low-fat dairy foods and whole grains. The diet is rich in potassium, magnesium and calcium, as well as protein and fiber, and low in sodium. Foods on the diet are low in saturated fat, total fat, and cholesterol.
Meditate or take slow, steady deep breaths to calm the nervous system, relax and your dilate blood vessels. Breathing exercises help calm your sympathetic nervous system and your fight-or-flight response. This technique also encourages blood flow to your body’s tissues and causes your diaphragm to move up and down, which eases blood flow to your heart.
Eat beets: Rich in vitamins and minerals, this root vegetable can help decrease blood pressure. A 2010 study in hypertension found that drinking only 250ml of juice was needed have a positive effect on blood pressure. Many of the participants saw lowered blood pressure within 24 hours. Another study from 2012 saw that beetroot juice helped lower systolic blood pressure.
