Dietary patterns and inflammatory bowel disease: a global assessment of eight nutrients by region, gender, and socioeconomic status

This study found that between 1990 and 2018, processed meat intake increased the most across 185 countries, rising by 26%, mirroring the global rise in IBD burden. The intake of eight dietary components showed significant heterogeneity across global populations, with variations by age, education level, and urbanization. These findings may inform policy interventions aimed at reducing intake in high-risk groups with high consumption of dietary factors linked to IBD, particularly in high-income countries and Asia, where IBD burden is increasing rapidly. The sharp rise in processed and unprocessed red meat intake, combined with long-term underconsumption of fruits, vegetables, and dietary fiber, likely contributes significantly to the rising IBD burden.
