Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood [1]. According to Healthgrades, while taking atorvastatin, it is important to avoid foods high in cholesterol, such as fatty meats like pork, as they can interfere with the effectiveness of the medication [2]. Pork is known to be high in cholesterol, with a 3-ounce serving of pork containing about 65 milligrams of cholesterol [3]. Therefore, it is recommended to limit or avoid pork consumption while taking atorvastatin to ensure the medication works effectively in lowering cholesterol levels. It is advisable to consult with a healthcare provider or a registered dietitian for personalized dietary recommendations while taking atorvastatin [2].
