The dark cola drinks also need to be avoided as they are rich in phosphorus which tends to accumulate. Foods that
are high in protein
are meat, poultry (chicken), fish,
eggs, and dairy products (milk, cheese, yogurt) should be taken in lesser amounts as they are to be excreted by kidneys and hence increase the renal workload. There’s no drug to decrease creatinine levels but the only way is to find out the underlying cause of the deranged kidney function and rectify the same.
