Rigatoni Overview

Rigatoni is a tube-shaped wheat pasta that is high in carbohydrates. Like most traditional pasta, it is made from refined flour and digests quickly, which can raise blood sugar in typical portions. Rigatoni is not suitable for keto and is generally not diabetic-friendly in standard servings. Low-carb swaps include shirataki noodles, zucchini noodles, or hearts-of-palm pasta.
