British researchers have discovered that feeding mice a diet devoid of a dietary compound (AhR) found in the cruciferous vegetables (cabbage, broccoli, bok choy) lowered the function of specialized immune cells that patrol the intestinal wall. If confirmed in humans, it would support the many benefits of consuming these vegetables.
