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.
Much of the salt we ingest comes from fast food, ready-made meals, bread and soft drinks – things to avoid when on a low-carbohydrate diet. This will lower your salt intake automatically. Furthermore, the hormonal effects of LCHF make it easier for the body to dispose of excess salt through urine; this can explain the slight lowering of blood pressure.
Ask your doctor if low-fat or nonfat milk is better than whole milk for you. Whole milk can lower blood pressure better than low-fat or nonfat milk, but there may also be risks. Whole milk contains Palmitic acid, which, according to some studies, can block internal signals responsible for relaxing blood vessels. As a result, your blood vessels stay constricted and your blood pressure remains high.
Another study by UCLA researchers of 1,117 men and women with high blood pressure reported that within three weeks of arriving at Pritikin, systolic blood pressure fell on average 9%. Diastolic pressure also fell 9%. Of those taking blood pressure drugs, 55% returned home medication-free. Many of the remaining 45% left Pritikin with their dosages substantially reduced.2
10. Increase intake of potassium: Potassium is important to keep blood pressure under control as it helps the body to get rid of sodium. Including more fresh and whole foods in your diet can contribute to healthy levels of potassium in your body. Foods rich in potassium include bananas, beans, nuts and seeds, tuna, salmon, dairy products and green leafy veggies are rich sources of potassium.
A 2013 review on yoga and blood pressure found an average blood pressure decrease of 3.62 mm Hg diastolic and 4.17 mm Hg systolic when compared to those who didn’t exercise. Studies of yoga practices that included breath control, postures, and meditation were nearly twice as effective as yoga practices that didn’t include all three of these elements (24).
Some research on watermelon extract and high blood pressure suggests the amino acid citrulline found in the fruit may help manage high blood pressure. One study found those who took watermelon extract showed reduced blood pressure specifically in the ankles and arm arteries. Other studies on mice also show watermelon’s positive effect. Although more research is needed to determine the specifics, eating fruit like watermelon isn’t going to hurt.
Get moving at least a little bit every day, with a standard recommendation of 30-60 minutes a day, 3-5 times a week. Get your heart pumping at a moderate intensity for a few times a week, and mix it up with some strength training. Because life happens, on the days when you can’t fit it in, try to build more activity into your day by parking further away, taking the stairs instead of the elevator, or even just doing a quick sprint or two up and down the block. Every little bit helps.
