At age 29 I was diagnosed with a mild hypertension. But about twelve years ago (I'm 61 now), I was diagnosed with malignant hypertension. The systolic was greater than 210. An optometrist had discovered hypertensive retinopathy during an exam. At the time, I was given enough meds to bring it down to reasonable levels.
So when I went McDougall, My BP came down a bit and I stopped my meds and ate low sodium, but after a while it persisted in the high 140 to mid 150 area. Only by quitting added salt completely would it go down further. It's now at the mid to high 120s That means zero salty packaged food and zero salty restaurant food for me. I don't use salt on my rice and home-cooked beans, but I do use sriracha sauce. It's pretty low sodium compared to most hot sauces. I keep soy sauce in a squeeze bottle so I can apply it by the drop! I'd say my daily intake of sodium contained in the foods naturally plus added in hot sauce and soy sauce is about 500 mg per day. I don't do breads from the supermarket because the sodium is so very high, but Safeway makes a whole wheat sodium-free sandwich bread.
I once had two little 99¢ Taco Bell bean burritos fresco style (salsa instead of cheese) and the next day my systolic had shot up to 160. I looked them up online and discovered they each had 1,000 mgs of sodium! So I must be very strict. The way food tastes to me now is just fine as long as everything I eat has no added sodium. Eating a salty food can quickly skew my taste buds into thinking the other food is bland.
Walter Kempner treated hypertension with his famous no-sodium rice diet. Alan Goldhamer at True North is a proponent of no sodium in the food. They can get just about everybody's BP down to normal by making them do a water fast. That's zero sodium! Dr. Greger today released an interesting video about how the salt industry is behind a campaign to sow doubt on the effectiveness of no sodium eating.

I'm used to eating salt free now and I've never been healthier. I compliment my foods with hot sauce and/or sour flavors that come from vinegar, lime juice, lemon juice, and tamarind.
Also, giving up caffeine was good for a few BP points and it freed me of being groggy in the morning because of caffeine withdrawal. I stopped caffeine after I had been doing this way of eating for several months. There's no rush.
