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.
Consider once again the analogy of the garden hose. If you turn on the water “harder,” there is more pressure in the hose. Excessive salt in the diet can result in excessive fluid volume in the blood, which results in elevated blood pressure. This cause, too, is reversible, as a plant-based diet of whole, natural foods, devoid of added salt, is naturally low in sodium chloride.
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.
It’s a common question among our guests at the Pritikin Longevity Center, who are taught how devastating the high-salt U.S. diet is to our blood pressure and overall health. Searching for alternatives, people often ask: What about salt substitutes with potassium? And what about MSG? Isn’t it a bad choice? Here are answers, some of which may surprise you.
It goes without saying that when you don’t sleep well, you don’t feel well, and your body just doesn’t work well. In fact, research has shown for decades that a strong link between insomnia and hypertension exists. Reevaluating your daytime decisions or nighttime routines leading up to bedtime can help you find what works best for you in getting a good night’s rest.
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.

Kiwis are another fruit that positively impacts blood pressure. Some researchers studied how the fruit fares compared to apples. They found that eating three kiwis a day over eight weeks reduced blood pressure in people with slightly high blood pressure more so than eating one apple per day during the same time. A daily serving of kiwi was also found to reduce blood pressure in people with only mildly elevated levels. Kiwis are also an excellent source of vitamin C which can also also improve blood pressure.
