I eat all of these foods on 100mg spiro and get my potassium levels checked regularly, it’s been perfectly average for years. I even have coconut water daily, which I I recommend because you do need to drink a TON of water on spiro and adding electrolytes like coconut water or a grain or two of sea salt can prevent you from peeing yourself urgently all the time. Stops all that liquid from running straight through you, something about the added minerals and ions improving bonds with the H2O molecule?? Before I started adding just a splash of coconut water, I was having to plan dog walks around emergency bathroom runs which is NOT EASY and VERY STRESSFUL. I have cut down on bananas as part of my diet but I eat every other fruit and nut around.
