Red Meat Avoidance Won’t Prevent Flares in Crohn's

Key clinical point: For adults with baseline-remitted Crohn’s disease, eating red and processed meat no more than once per month did not reduce the risk of relapse.

Major finding: After 49 weeks, there were no significant differences in time to any symptomatic relapse between the high– and low–red meat groups.

Study details: Randomized controlled trial of 213 adults with remitted Crohn’s disease who were told to consume red or processed meat at least twice weekly or no more than once monthly.

Disclosures: The Crohn’s and Colitis Foundation and the National Institutes of Health supported the work. Dr. Aldenberg disclosed receiving research funding from Seres Therapeutics. Two of six coinvestigators disclosed ties to Nestle Health Science, AbbVie, Pfizer, Eli Lilly, and several other pharmaceutical companies.
