I came across this statement on Selfhacked:
If you have high cortisol, you will do worse with a high salt diet and you will be potassium deficient in the long term (few people as it is get the RDA). But taking potassium supplements is not simple, because the deficiency is in your cells, not your blood. Also, potassium raises cortisol, which isn’t good if you already have high levels. Cortisol is anti-inflammatory, but it can also cause arthritis by inhibiting collagen formation and also by lowering cell potassium. Cell potassium is always low in rheumatoid arthritis (R). The answer is to reduce stress.
I tried searching for any proof of this, but haven't been able to find. Is this true? Does potassium really raise cortisol? Are there any published research articles confirming this?
Does it follow from this (if true) that a constant overdose of potassium-rich foods may cause a Cushing-like state? This sounds doubtful to me.
