From Geoff Fletcher, Melbourne, Australia
I started using low-sodium “heart” salt about four months ago, having read about its effect on reducing blood pressure. I am in my 70s and I have regular blood tests. After a test five weeks ago, my doctor was concerned about high potassium levels in my blood, so I told him what I had been doing (8 June, p 32).
I take amlodipine/valsartan to control my blood pressure, which apparently helps the body store potassium. If you are also consuming potassium chloride in salt, this can lift potassium to dangerous levels. I stopped using the “heart” salt immediately and my potassium levels have returned to normal.
