In children without autism, eating an anti-inflammatory diet for 12 weeks leads to small improvements in visual-spatial tasks, attention, and how quickly they process information, but these changes happen without noticeable changes in immune system markers, suggesting the diet may help cognition through metabolism, not inflammation.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether anti-inflammatory diets consistently improve visuospatial processing, attention, and processing speed in neurotypical children without altering inflammatory biomarkers.
A systematic review and meta-analysis of at least five RCTs measuring pre-post cognitive outcomes (WISC-IV Processing Speed, Block Design, CPT) and inflammatory biomarkers (CXCL1, RANTES, IFN-γ) in neurotypical children aged 6–16 receiving structured anti-inflammatory diets vs. control diets.
Whether an anti-inflammatory diet improves visuospatial processing and attention in neurotypical children independently of changes in inflammatory markers.
A double-blind RCT with 100 neurotypical children aged 6–16 randomized to a 12-week anti-inflammatory diet (NeuroGutPlus) or an isocaloric control diet, measuring pre-post cognitive outcomes (Block Design, CPT, Digit Symbol) and plasma inflammatory biomarkers (CXCL1, RANTES, IFN-γ) and TMAO, with blinded assessors.
Whether baseline TMAO levels predict cognitive improvements in neurotypical children following an anti-inflammatory diet.
A prospective cohort study following 150 neurotypical children for 12 months, measuring TMAO and cognitive performance (visuospatial, attention) before and after dietary intervention, adjusting for baseline diet, physical activity, and sleep.
Whether neurotypical children with greater cognitive improvement after an anti-inflammatory diet have larger reductions in TMAO compared to those with minimal improvement.
A case-control study comparing 40 neurotypical children with ≥0.5 SD cognitive improvement on an anti-inflammatory diet to 40 with <0.5 SD improvement, matched for age and baseline cognition, measuring pre-post TMAO and inflammatory biomarkers.
Whether TMAO levels are inversely correlated with visuospatial and attention performance in neurotypical children at a single time point.
A cross-sectional analysis of 200 neurotypical children aged 6–16, measuring plasma TMAO and cognitive performance (Block Design, CPT-II) at one visit, adjusting for age, sex, BMI, and dietary intake.
