When undergoing CAR T-cell therapy, avoiding certain foods is crucial to minimize infection risks and optimize the efficacy of the treatment. Based on research findings, here's a list of foods to steer clear of:

  • Meats and Fish: Steer clear of uncooked seafood like sushi, undercooked shellfish, and meats that are not thoroughly cooked (such as steak tartare and pate). Also, it's best to avoid deli meats and smoked items like smoked salmon, parma ham, and salami.
  • Eggs: Stay away from raw or slightly cracked eggs. This also extends to foods made with raw or partially cooked eggs, including homemade mayonnaise, mousse, Hollandaise sauce, egg nog, and meringue.
  • Dairy Products: Unpasteurized dairy items and matured cheeses like Brie, Camembert, Feta, and Blue cheeses (including Stilton, Danish Blue) should be avoided. Choose safer alternatives like hard cheeses, processed cheeses, or dairy products that have been pasteurized.
  • High Sugar Foods: Limiting the intake of high sugar foods might be necessary during the therapy. Utilize artificial sweeteners and opt for healthier choices such as tinned fruit in natural juice or fresh fruit.

Remember, these guidelines can vary based on individual circumstances. Therefore, it's recommended to seek personalized advice from a healthcare professional or a nutritionist who is knowledgeable about CAR T-cell therapy.
