In studying the different diets I'm supposed to be on to control my systemic diseases, several of which are contradictory, it looks like I'm going to be limited to lean low-sodium meat, lemons, avocados, and the very few low-oxalate, low-fiber vegetables in existence. I may have to compromise concerning a few things. For example, cauliflower is low oxalate, but has fiber (fiber is wrecking my digestive tract...I'll post a medical blog later), so I will have to reduce my portion to a cup or less per day. I can't even eat spinach or fruit because they are foods high in oxalate, and fruit has the added issue of fructose. Back when I made those sports drinks with red/green powder (I even posted a recipe), I started having kidney stones again, and had to cease the red/green powder and juice immediately. It is something I've confirmed...the stones are definitely made of oxalate. That has thrown a huge wrench in my already-challenging meal plans. The one thing I've found that is approved in every diet I listed is avocados. It would be in my best interest to adopt them as my new BFF.
I don't want to eat the same few things every day, so I'll have to see how creative I can get with the list I'm compiling. Food shouldn't be this complicated, but I'm going to do the best I can.
