Loading up on potassium-rich fruits and vegetables is an important part of any blood pressure-lowering program, says Linda Van Horn, PhD, RD, a professor of preventive medicine at Northwestern University Feinberg School of Medicine. Potassium encourages the kidneys to excrete more sodium through urination, and that sodium excretion can help lower blood pressure.
Also common for the pulse to increase when the systolic blood pressure goes down, that is the heart compensating for low BP. In your case, it may or may not be an indication that your body is finding a systolic BP of 100 to be on the low side. I would consider a systolic BP of 100 to be low for someone on BP medications; there are a few medical conditions that warrant a lower BP but for garden-variety essential hypertension, I’m not aware of any randomized studies that have demonstrated better outcomes at such a lower SBP.
Speaking of BP meds that effect potassium, my potassium is usually around 3.3 which is below the threshold. My doctor thinks this is due to the diuretic chlorthalidone and recommends a supplement like KLOR. I also take lisinopril and amlodipine. I have no symptoms of hypoglycemia and have put off taking the supplement. Perhaps switching to a potassium sparing diuretic would be the way to go, but I tolerate my current meds very well. I am a very active 75 year old man. Thank you so much for your good work with this blog.
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.
