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.
📊 Nutrition at a Glance
How the form changes the number: preparation is the real variable across this family. Boiling leaches a meaningful share of soluble oxalate into the cooking water — commonly 30-50% for plant foods — while raw and dry-heat forms keep essentially all of it, so the same base food can land in different brackets depending on how it is cooked. This page tracks Spaghetti Pasta at 1 mg per serving, at the low end of the family. Related forms in this family: Penne Pasta (1 mg), Rice Pasta (7 mg), Macaroni Pasta (1 mg).
