A very revealing article. I had a massive brain haemorrhage 20 years ago which left me paralysed on my left side. During a lengthy period in rehab I mysified the medical staff for months by having a very high level of salt in my blood but having a relatively low salt diet (not a health thing, I simply dislike salty food.) After a lot of fun, with doctors and nurses using subterfuge to try and find out where Iwas keeping my secret stash of salt, a retired family doctor who helped out in the rehab centre (which specialised in brain injury,) linked the fact that my sodium level was high and my potassium level very low. This jogged a memory for him and he called in an endocrine specialist.
Turned out I had developed something called Conn’s syndrome, enlarged adrenal glands were pumping out too much of a hormone called aldostetone, which balances blood electrolytes.
The usual causes are pregnancy and menopause, which were quickly ruled out in my case and after a lot of conversations and tests the verdict was it had been brought on by stress.
Later I did my own research on the demonisation of salt — I’d learned from the endocrinologists a healthy body simply rejects surplus salt as it does other chemicals which are essential in trace amounts — and found the whole case against salt, like that against saturated fats, was based on very shaky evidence and the influence of some very large egos.
