Pasta made from refined white flour is one of the safest carb sources for kidney stone patients — about 1 mg oxalate per cup of cooked spaghetti. Whole wheat pasta runs higher (15-25 mg) for the same reason as bread: the bran contains oxalate. The pasta itself is rarely the problem; it's what you put on it. Marinara is fine (tomatoes are low oxalate). Alfredo is fine (cream and cheese add protective calcium). The real oxalate traps are spinach-stuffed ravioli, spinach lasagna, and dishes where spinach or beet greens are the main vegetable. The pasta is innocent. For a completely safe pasta night: spaghetti with marinara and a generous sprinkle of parmesan.
