Whole food diet induces remission in children and young adults with mild-moderate Crohn's disease and is more tolerable than exclusive enteral nutrition: a randomized controlled trial
Abstract
BACKGROUND
Tasty&Healthy (T&H) is a whole-food diet for Crohn's disease (CD), which excludes processed food, gluten, red meat, and dairy, without requiring formula or mandatory ingredients. TASTI-MM was a clinician-blinded, randomized-controlled trial comparing tolerability and effectiveness of T&H vs. exclusive enteral nutrition (EEN).
METHODS
Patients with biologic-naive mild-moderate CD aged 6-25 years were randomized to either T&H or EEN for 8 weeks, receiving weekly dietary support. Tolerability was evaluated by weekly interviews, questionnaires and intake diaries. Other outcomes included symptomatic remission, Mucosal-Inflammation Non-Invasive (MINI) index, calprotectin, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Fecal microbiome was analyzed by metagenomics at baseline, week-4 and week-8. Data were analyzed by the intention-to-treat approach unless specified otherwise.
RESULTS
Among 83 included patients (41 T&H, 42 EEN; mean age 14.5±3.7 years), 88% tolerated T&H vs. 52% for EEN (aOR 7.7 [95%CI 2.4-25]; p<0.001). Calprotectin, CRP and ESR decreased significantly in both groups, with no between-group differences. Symptomatic remission was achieved in 56% of T&H group vs. 38% of the EEN group (aOR 2.5 [0.98-6.3], p=0.1; per-protocol: 67% vs. 76%; p=0.47). Calprotectin <250μg/g was achieved in 34% vs. 33% (aOR 0.97 [0.37-2.6], p=0.84) and MINI<8 in 44% vs. 31% (aOR 1.8 [0.7-4.5]; p=0.33). Microbiome α-diversity improved in the T&H arm and declined…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 83 participants or records.
