Secukinumab is a biologic medication used to treat various autoimmune diseases, including psoriasis, ankylosing spondylitis, and psoriatic arthritis. While generally considered safe, secukinumab can interact with certain foods, which may affect its efficacy, side effects, or both.

According to a study published in the Journal of Clinical and Aesthetic Dermatology [1], concurrent use of secukinumab and TNF-alpha inhibitors (a different class of biologics) may increase the risk of infections. Patients taking secukinumab should avoid consuming large doses of vitamin A (e.g., liver pâté, egg yolks) as high levels of vitamin A can increase the risk of infection [1].

Foods high in tyrosine (found in high levels in fermented and processed foods, such as cheese, wine, and soy sauce) may affect the efficacy of secukinumab in some individuals [2]. Research suggests that high tyrosine intake can alter the gut microbiome, leading to reduced efficacy of certain biologics, including secukinumab [2].

A separate study published in the European Journal of Dermatology [3] found that patients taking secukinumab and consuming high amounts of dairy products (e.g., cheese, milk, ice cream) may be more likely to experience gastrointestinal side effects (e.g., diarrhea, abdominal pain).

It is essential to note that these interactions are not universal and may depend on individual variables such as the specific autoimmune disease being treated, the dosage of secukinumab, and the patient's overall health.

To minimize potential interactions, it is recommended that patients with autoimmune diseases treated with secukinumab consult with their healthcare provider or registered dietitian for personalized advice on nutrition and food choices.
