Well thats caused by obesity , lack of exercise, bad diet. You can also take pills to fix it.
But baseline BP is all about diet, exercise, good sleep routine and avoiding smoking.
Some foods like licorice can elevate BP; the glycyrrhizic acid inhibits an enzyme that deactivates cortisol.
I personally drink hibiscus tea a few times a week which is an ACE inhibitor and is shown to reduce systolic blood pressure by 5-7mmHg. Also the occasional beetroot juice (+ apple and carrot) or magnesium bisglycinate for a 2-5mmHh systolic reduction due to the nitric oxide.
