Lipitor is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins, which work by blocking an enzyme in the liver that produces cholesterol. There is no specific type of nuts that has been recommended to be consumed or avoided while taking Lipitor [1].

According to a study published in the Journal of the American College of Cardiology, consuming nuts, including almonds, walnuts, and pistachios, may help to lower LDL cholesterol levels, which is the "bad" cholesterol [2]. However, this study did not specifically look at the effects of nuts on individuals taking Lipitor.

Another medication used to lower cholesterol levels is Zetia, which works by blocking the absorption of cholesterol in the small intestine [3]. There is also no specific type of nuts that has been recommended to be consumed or avoided while taking Zetia.

In summary, there is no specific type of nuts that has been recommended to be consumed or avoided while taking Lipitor or Zetia. However, consuming nuts may help to lower LDL cholesterol levels in general [1][2][3].
