There are no known food interactions with Stelara (ustekinumab). However, potential interactions have not been fully studied, so consult your doctor about any necessary dietary adjustments. While Stelara itself doesn't have direct food interactions in the way some medications do, it's important to understand how it affects your immune system and how certain foods can impact inflammatory conditions.

Should I Change My Diet While on Stelara?

Dietary recommendations may vary based on your condition. For example, if you are taking Stelara for Crohn’s disease, your doctor may advise avoiding foods that worsen symptoms.

Stelara may raise your risk of infections, so taking precautions is important:

  • Avoid raw or undercooked meat, poultry, and eggs to reduce the risk of salmonella or other infections.
  • Practice good hygiene and avoid contact with sick individuals.

Foods to Be Mindful Of While Taking Stelara:

  • Undercooked foods: Avoid undercooked meats (especially poultry and seafood), raw eggs, and unpasteurized dairy products. These can carry bacteria that pose a higher risk of infection when your immune system is suppressed.
  • Foods high in sugar: Sugary foods can contribute to inflammation, which can worsen symptoms of the conditions Stelara treats.
  • Foods high in saturated and trans fats: These fats can also increase inflammation. This includes fried foods, processed snacks, and fatty meats.
  • Processed foods: Highly processed foods often contain unhealthy fats, sugars, and additives that can promote inflammation.
  • Alcohol: While not a direct interaction, alcohol can increase inflammation and may also increase some of the side effects of Stelara.
  • Unpasteurized dairy products: Raw or unpasteurized milk products can carry bacteria that are dangerous for people with comprimised immune systems.
