IL10 and colitis: Impact of ingestion (either in drinking water or incorporated within the diet, short‐ and long‐term) of five emulsifiers [polysorbate 80, lecithin and sodium dodecyl (lauryl) sulphate plus two selected from the in vitro studies] will be studied in wild‐type C57BL/6J and Il‐10‐/‐ mice (a colitis‐susceptible model relevant to human IBD).
