Right. Yes it's diet related but that's because most American's diets are awful in general. As an n=1 bit of anecdote, I had hypertension for years, capping out somewhere around 180/120. I was put on low sodium diets with no change at all. I was put on blood pressure medication, with modest benefits. Then one year I arrived at my annual physical with a dramatic drop. What changed? I lost 30 pounds. The next year I arrived with another notable drop, now square in the normal BP range. What changed? I lost another 10 pounds and had picked up a fair amount of cardiovascular exercise. During this time period and to this day I never bother limiting my sodium intake, and I both have a heavy hand in the kitchen as well as eat out a lot, both leading to high levels.
