"I can't eat bananas as I have hyperkalemia" and I'm not a fruitarian, too much potassium fruits, and also nuts, fish, sea food, steak, milk, (especially powdered) juices, drinks, brewed coffee, green vegetables, beans, and dark chocolate). Too much potassium will slow the heart.and if not controlled can lead to the heart stopping. It is after-all the main part of the lethal injection, the other two injections are a paralytic, and a soporific (barbiturate)
Before I was diagnosed my resting heart rate was measured at between 35- 38bpm minute, now by controlling my diet it way up to 40 - 44 bpm.
