Here's what that Wikipedia article about Kidney stones really says:
"Certain foods may increase the risk of stones: spinach, rhubarb, chocolate, peanuts, cocoa, tomato juice, grapefruit juice, apple juice, soda (acidic and contains phosphorus), all types of tea, and berries (high levels of oxalate)."
"A high protein diet might be partially to blame."
Should we stop eating spinach or berries to avoid kidney stones?...
BTW, the article also mentions that "protein from meat and other animal products is broken down into acids."
ALL proteins (not only animal proteins) are broken down into acids.
To avoid kidney damage when eating (lots of) proteins, drink plenty of water to flush the kidneys.
