Based on the information available, there are no known food-drug interactions between tofu and Lipitor (atorvastatin), a medication used to treat high cholesterol. However, it is always important to consult with a healthcare provider or pharmacist for personalized advice, as individual circumstances can influence drug interactions.

Tofu is a soy-based food that is low in saturated fat and cholesterol, making it a heart-healthy choice for many individuals, including those taking Lipitor. Furthermore, the American Heart Association recommends including soy foods as part of a heart-healthy diet.
