My sister in-law had a basic diet like that after she lost a kidney.There’s a specific diet for kidney disease…you limit salt, potassium, phosphorus….also beef and pork….some veggies and fruits are out, have to be very careful about processed food ingredients.
Basically, I have chicken or fish with veggies for dinner…..eggs and toast with jam for breakfast, fruit for snacks. Water to drink (black coffee in the morning).
The goal is to stay off dialysis for as long as possible.
