Lipitor is a medication used to lower cholesterol levels in the blood. According to the provided source [1], there is no indication that Lipitor causes lactose intolerance with skim milk. However, it is important to note that Lipitor can interact with other medications and foods, so it is recommended to consult with a healthcare provider before consuming any dairy products while taking Lipitor.

When it comes to heart health and milk consumption, the type of milk matters. Skim milk is a good choice for those with high cholesterol levels, as it contains less saturated fat than whole milk. According to the provided source [2], skim milk is considered a heart-healthy option, along with soy milk and almond milk.

Cheese is also a dairy product that can affect cholesterol levels. While cheese is high in saturated fat, some types of cheese, such as cottage cheese and feta cheese, are lower in fat and can be consumed in moderation as part of a heart-healthy diet. It is important to note that cheese should not be the main source of calcium in the diet, as it is also high in sodium. The provided source [3] recommends consuming no more than 30g of cheese per day.

In conclusion, there is no evidence that Lipitor causes lactose intolerance with skim milk. Skim milk is a heart-healthy option for those with high cholesterol levels, and some types of cheese can be consumed in moderation as part of a heart-healthy diet. It is important to consult with a healthcare provider before consuming any dairy products while taking Lipitor.
