After reviewing the sources, there is no evidence of any interactions between Lipitor and skim milk. Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood [1]. Skim milk is a low-fat dairy product that is a good source of protein, calcium, and vitamin D [2]. According to WebMD, there are no known food interactions with Lipitor [2].

The study published in the Journal of Clinical Lipidology examined the effects of atorvastatin on blood lipid levels in overweight and obese patients with type 2 diabetes. The study did not investigate any potential interactions between atorvastatin and skim milk [3].

It is important to note that while there is no evidence of any interactions between Lipitor and skim milk, patients should still consult with their healthcare provider before making any changes to their diet or medication regimen.
