Anti-Inflammatory Diet and Probiotic Supplementation as Strategies to Modulate Immune Dysregulation in Autism Spectrum Disorder.

Researchers studied how diet and probiotics affect immune system inflammation in 30 autistic children over 12 weeks. Children followed either a special anti-inflammatory diet (avoiding gluten, dairy, and artificial additives while eating foods rich in omega-3s) or took probiotic supplements. The anti-inflammatory diet showed better results at reducing inflammation markers and stabilizing immune function compared to probiotics alone. This suggests dietary changes might help manage immune-related issues commonly seen in autism.

This randomized controlled trial examined immune system changes in 30 children with autism following 12 weeks of either an anti-inflammatory diet or probiotic supplementation. The anti-inflammatory diet (low in gluten, FODMAPs, casein, and artificial additives; high in omega-3s and polyphenols) significantly reduced IFN-γ levels and stabilized immune profiles. Probiotic supplementation (16 strains) increased IL-8 and MIP-1β while decreasing IFN-γ, suggesting changes in innate immune responses. Eight of eleven biomarkers showed significant differences between groups post-intervention.

Results indicate that anti-inflammatory diets may provide broader and more consistent immune regulation effects compared to probiotics alone in children with ASD.

Findings suggest anti-inflammatory dietary approaches may be more effective than probiotics alone for immune regulation in autism. This supports considering precision nutrition strategies as complementary interventions. However, larger, longer-term studies examining both immune and behavioral outcomes are needed before making clinical recommendations. Individual responses may vary significantly.

Small sample size (30 children with ASD) limits generalizability. Short 12-week intervention period may not capture long-term effects. Study did not report on behavioral or functional outcomes, focusing only on immune biomarkers. Control group composition and randomization details are unclear from the abstract.

: Autism spectrum disorder (ASD) is a neurodevelopmental condition associated with behavioral and cognitive impairments. Increasing evidence also links ASD with systemic immune dysregulation, including abnormal cytokine profiles and chronic low-grade inflammation. Emerging evidence suggests that targeted dietary strategies and probiotic supplementation may modulate immune responses and gut-brain interactions in patients with ASD. This study aimed to evaluate the immunomodulatory effects of a structured anti-inflammatory diet () compared to multi-strain probiotics in children with ASD.is a nutritionally complete anti-inflammatory dietary protocol that targets gut integrity, inflammation, and mitochondrial function.

It includes a diet low in gluten, FODMAPs, casein, and artificial additives, and a high intake of omega-3 fatty acids, polyphenols, and fermentable fibers.: A total of 30 children with ASD and 12 neurotypical controls were enrolled in a 12-week randomized controlled nutritional trial. Participants received either aanti-inflammatory diet, probiotic supplementation (16 strains ofand Bifidobacterium), or no intervention. Plasma levels of 20 cytokines and chemokines were measured pre- and post-intervention using multiplex Luminex immunoassays. Principal component analysis (PCA) was used to explore shifts in the immune profile.: Patients treated with thediet significantly reduced IFN-γ levels (= 0.0090) and showed a stabilizing effect on immune profiles, as evidenced by PCA clustering.

Probiotic supplementation led to a significant increase in IL-8 (+66.6 pg/mL;= 0.0350) and MIP-1β (+74.5 pg/mL;= 0.0100), along with a decrease in IFN-γ (= 0.0070), suggesting reconfiguration of innate immune responses. Eight out of eleven biomarkers showed significant post-intervention differences between groups, indicating distinct immunological effects.: This study provides evidence that anti-inflammatory diets exert broader and more consistent immunoregulatory effects than probiotics alone in children with ASD. These findings support the inclusion of precision dietary strategies as non-pharmacological interventions to mitigate immune-related dysfunction in patients with ASD.
