I understand why your physician says that, but each individual is a different case. I'd say it's the silent killer for most
people. I have low blood pressure--all the time. My family doc in Ohio was always on me about not adding salt to my diet, so I decided he wasn't doing his due diligence. On an occasion when I knew I would be going to see him, I went three days without adding salt to any of my food. My BP was 90/50. So he comes in and tells me there seems to be a problem with my BP. No ****, Sherlock. So I explained to him what I'd done, and it took about fifteen minutes more while he poked and prodded me for him to (grudgingly) admit that I might
have chronically low BP. I crave salt, all the time.
