I would suggest:
1. Potassium Chloride for those who "just HAVE to have" their salt taste
2. Mrs. Dash (tastes great on just about everything)
3. Spike (Similar to Mrs. Dash, less pepper. Usually found in health food stores)
4. Ground ginger (Tastes great on lots of things, even ones you wouldn't think to try it on. Also has an immune system boosting effect.)
5. If bacon is a staple in your cooking/on your plate, try the Morningstar Farm's veggie bacon: my mother hates veggie meat substitutes, but loves this stuff. It has half the sodium of regular bacon, more potassium, and much less fat and cholesterol. Don't forget, most that are hypertensive also have a problem with either fat or their cholesterol as well.

My mother is hypertensive. We (sister+me) grew up without cooking with salt or really even eaten overly salty foods. But, it did have a down side when I was 13 and playing ice hockey: I would sweat a bunch and replace the potassium, but not the salt component lost. Ended up with cramps in my legs. Started eating either cheese or fries with what I call heavy salt (less than most fast food places put on theirs though) and was fine.
