An Australian study discovered that a gene called T-bet may play an integral role in promoting good digestion.
This gene signals the production of immune cells, known as innate lymphoid cells (ILCs) in the gut. T-bet may act in response to the proteins in cruciferous vegetables, such as cabbage, watercress, kale, collards, bok choy, broccoli, and cauliflower that produce these ILCs. This connection shows the importance of the foods we ingest and our subsequent immunity as a whole.
