It is an extremely common belief that high protein intake leads to bubbly urine, kidney damage and so on so forth!
However, bear in mind that most recent scientific evidences showed that NO effect on kidney function was observed, in NORMAL, HEALTHY individuals
These are the possible side effects instead however, if you consume too much protein!
1. Gain fats or weight (because protein are extra calories too!)
2. Increased calcium excretion (bad for your bones if you don't do enough exercise or training!)
3. Expensive for your wallet! Unnecessary cost!
