“Avocados?” I was incredulous.

“Oh, yes. And, of course, bananas.”

I knew about the bananas. When I just to jog [before my knees interfered], I would come back after 10 or more miles and devour banana nectar. Loved the stuff. That potassium hit was supreme restoration. The sugar was not bad, too.

Now, I was being told to avoid one of my favorite fruits. And avocoados to boot. [I know, avocados are fruit, just like bananas, but I find it hard to consider them a fruit. More like nirvana.]

I was having a conversation with an assistant to a urologist. I was paying a painful visit because I was in the midst of an attack of kidney stones. The assistant was giving me a list of foods to avoid. The key: keep your potassium consumption low.

Thing is, the night before, when I was having bad muscle spasms from the stones, I was eating comfort food — guacamole — and plying my pain with a banana daiquiri. Now I was learning why I just might have been aggravating my situation.

I was given two lists: foods with high potassium to avoid and foods that are low in potassium and safe. Having learned a painful lesson, I thought I would pass the information along. Yes, I think I won’t have any issue avoiding prune juice. And chocolate, well, I certainly can cut down from my daily one pound. 15, maybe even 14 ounces.

Life is not fair.
