The bottom line:

If I tell my young patient that his renal failure is due to carbonated drink/coca-cola, whatever drink it is, without doing any further investigation, I will probably have to talk to his lawyer second day.

 

Common things are common first for renal failure: In US, Diabetes, hypertension, ...IgA nephropathy is common in China.  Glomerulonephritis; ANCA, anti-GBM, lupus....  Obstructive nephropathy.

 

Fructose-uric acid-CAD/CKD is already known, but not NaHCO3, as you'd mentioned.

 

Without doing these investigation before simply blaming carbonated drink, it is simply crazy!  I do not think most Chinese doctors will even think this kind of post is correct.  It is just some "Public media stunning"!
