After reviewing the sources, there is no evidence to suggest that Lipitor, a medication used to lower cholesterol, decreases avocado absorption. Lipitor works by blocking the production of cholesterol in the liver [2]. Avocado, on the other hand, is a heart-healthy food that can help lower cholesterol levels [3]. It is important to note that while avocado can be beneficial for individuals with high cholesterol, it should not be used as a substitute for cholesterol-lowering medication prescribed by a healthcare provider [3].

In conclusion, there is no evidence to suggest that Lipitor decreases avocado absorption. Avocado is a heart-healthy food that can help lower cholesterol levels, but it should not be used as a substitute for cholesterol-lowering medication prescribed by a healthcare provider.
