After conducting research based on the information provided, I found that Lipitor, a medication used to treat high cholesterol, can interact with certain foods. However, there is no specific mention of sushi being a food to avoid while taking Lipitor.

Lipitor, also known as atorvastatin, can interact with grapefruit and grapefruit juice [1]. Consuming these can increase the amount of Lipitor in your blood, which can increase the risk of side effects.

As for sushi, it is generally safe to consume while taking Lipitor. However, it's important to note that sushi can contain high levels of sodium and fat, which can affect your overall health if you have high cholesterol. It's always a good idea to maintain a balanced diet and consult with your healthcare provider about any concerns you may have regarding your diet and medication.

In conclusion, while sushi is generally safe to eat while taking Lipitor, it's important to be mindful of the potential interaction between Lipitor and grapefruit and grapefruit juice. Always consult with your healthcare provider for personalized advice regarding your diet and medication.
