A long-term study concluded in 2014 found that people who ate more protein had a lower risk of high blood pressure. For those who ate an average of 100 grams of protein per day, there was a 40 percent lower risk of having high blood pressure than those on a low-protein diet (33). Those who also added regular fiber into their diet saw up to a 60 percent reduction of risk.
Scientists have long debated the effects of caffeine on blood pressure. But an analysis of 34 studies seems to have delivered a verdict. On average, consuming 200 to 300 mg caffeine (the amount found in one or two cups of coffee) raises systolic blood pressure by 8 mmHg and diastolic blood pressure by 6 mmHg. And the effects can last for up to three hours. (For reference, 8 ounces of drip coffee contain 100-125 mg of caffeine; the same amount of tea, 50 mg; an equal quantity of cola, about 40 mg.)
Other exercise options that don’t require a gym membership include body weight exercises, like pushups, squats, and jumping jacks. These exercises can be done at home or outside. For people who like going to the gym or running, these can be good ways to build community, notes Parker. Apps like Fitbit and MapMyRun can be helpful if you like keeping track of your steps, calories burned, weight, or number of miles run.

A study from 2008 showed that if you consume olive leaf oil there will be a significant change in your blood pressure. If you want to add olive leaf to your diet, you should look for fresh leaf liquid extracts for maximum results. You can also prepare your own olive leaf tea by placing a large teaspoon of dried olive leaves in boiling water. Let it cool down for 10-15 min and consume it fresh.
Low- and no-fat dairy foods are good sources of calcium and protein, which can help maintain a healthy blood pressure. Try to get three servings of dairy every day. Choose skim or 1% milk and low- or no-fat cheeses and yogurt. Frozen low-fat yogurt is OK, too. One serving equals 1 cup of yogurt or milk, or 1 1/2 ounces of cheese -- about the size of three dice.

As explained by Dr. Rosedale, insulin stores magnesium. If your insulin receptors are blunted and your cells grow resistant to insulin, you can't store magnesium so it passes out of your body through urination. Magnesium stored in your cells relaxes muscles. If your magnesium level is too low, your blood vessels will constrict rather than relax, which will raise your blood pressure and decrease your energy level. Insulin also affects your blood pressure by causing your body to retain sodium. Sodium retention causes fluid retention. Fluid retention in turn causes high blood pressure and can ultimately lead to congestive heart failure. If your hypertension is the direct result of an out-of-control blood sugar level, then normalizing your blood sugar levels will also lower your blood pressure readings into the healthy range.

In Sweden, blood pressure is often wrongly measured at clinics with the subjects lying down. The differences tend to be small, however: when seated, the systolic blood pressure registers a little lower, and the diastolic a little higher. Trying this on myself, I noted readings of 116/73 averaged over several seated measurements and an average of 119/72 lying down.
For example, eating a healthy diet rich in fruit, vegetables, whole grains, and healthy fats can limit dense low-density lipoprotein (LDL) deposits along the artery that contribute to high blood pressure. Limiting intake of processed foods can lower sodium intake and total cholesterol. This, in addition to exercise, can also help lead to weight loss. Research indicates that losing as little as nine pounds can have substantial impacts on blood pressure.

"This is notable because there (are) a lot of people out there with blood pressure in the 130s that we might previously have left alone, but if the results of this trial (are) as we think they are, it might be reason to try to get them to 120," said Dr. John D. Bisognano, professor of medicine at the University of Rochester Medical Center and president-elect of the American Society of Hypertension.
