Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood [1]. It works by blocking an enzyme that produces cholesterol in the liver. According to Drug Patent Watch, there are no known negative interactions between Lipitor and plant-based foods [1].

Plant sterols are compounds found in plant-based foods that have been shown to help lower cholesterol levels in the blood [3]. While they are not a substitute for medication, they can be used in conjunction with statins like Lipitor to further reduce cholesterol levels [3].

Zetia is another medication used to lower cholesterol levels, but it works differently than statins like Lipitor [2]. Zetia blocks the absorption of cholesterol in the intestines, while statins work in the liver [2].

In conclusion, there are no known negative interactions between Lipitor and plant-based foods [1]. Plant sterols can be used in conjunction with statins to further reduce cholesterol levels [3]. Zetia works differently than statins and blocks the absorption of cholesterol in the intestines [2].
