I can only offer n=1 advice. My bp used to average about 140/90. (age 56)
...Now minus carting around 50 extra pounds of spare fat, it averages about 117/70 (age 60)
Was it just the weight loss, or the change of diet? I don't know.
No wheat now, and not a lot of fruit any more, perhaps just one piece a week. (I used to often eat 5 pieces of fruit a day! Apparently it's 'good for you')
Don't just let the doctor supply a cushion, stop hitting yourself on the head.
