Separately, did everyone know how many different aspects there are to the simple phrase "renal diet"? Am I the only one who didn't know this? Phosphorus, potassium, sodium, protein, liquid restrictions? I kind of knew about sodium, protein and liquid restrictions, but the other stuff... Anyway, hope he likes it and hope it doesn't make him feel worse! Thanks all.
OP, my husband went through end stage kidney disease about 3 years ago and for a while had to be on a pre-dialysis renal diet. That was so hard and counter intuitive.
The kidney filters out potassium and phosphate, and it was failing to do its job, so we had to severely reduce those (generally healthy!) minerals. Phosphate is also a common substance in many preservatives, so I had to carefully read labels of all processed foods.
The pre dialysis diet (as I recall) was:
very low meat protein
moderate low in vegetable protein (beans, lentils, humus soy)
low in healthy leafy greens (lots of potassium) -- stick to ice berg lettuce
low in healthy green vegetables like broccoli and asparagus
radishes, celery were OK
no potatoes
low dairy
white bread, not whole grain bread
white rice not brown rice
marshmallows
you get the picture! It was so hard!
But we followed it for over a year and I do think it helped keep him feeling well while his kidney failed. He was able to stay off dialysis completely while we were waiting for the kidney transplant, which is pretty unusual.
It was a big surprise to me, how involved the kidneys are in nutrition.
