Potatoes I am supposed to boil twice changing the water to reduce the potassium and using the water to make a stock seriously frowned upon. Banana and avocado strictly off limit too so bananas and custard a distant memory
Pottasium and Phosphates for renal folk is the enemy so tomatoes coke ready made cakes dairy and cheese we have to be careful of.
The really high food I do steer clear of rice is ok and pasta and just eat everything else in moderation and use by blood test results as a barometer
Generally the diet is protein poor, Hypercalcemia the concern . Pastas and rice bread high in carbs which to normal people is a potential issue
All this of course keeps me temporarily out of trouble
