Based on the available information, there is no direct mention of diet guidelines provided in the sources given. However, I can provide you with some general information about Lipitor and dietary considerations related to its use.

Lipitor, a medication commonly prescribed to manage high cholesterol, contains the active ingredient atorvastatin. It works by reducing the production of cholesterol in the body, helping to prevent plaque buildup in the arteries and reducing the risk of heart attack and stroke [1][2].

While diet guidelines are not explicitly mentioned, it is essential to maintain a heart-healthy diet when taking Lipitor or any cholesterol-lowering medication. A heart-healthy diet typically includes:

1. Fruits and vegetables
2. Whole grains
3. Lean proteins (such as chicken, fish, and legumes)
4. Healthy fats (such as those found in nuts, seeds, and avocados)
5. Limiting saturated and trans fats, cholesterol, and sodium

These dietary recommendations aim to help manage cholesterol levels, maintain a healthy weight, and reduce the risk of heart disease [3].
