. . . new research finds connection between a healthy gut and cruciferous greens
A startling discovery has, in the words of one of the researchers involved, “thrown open a completely new way of looking at gut biology.” Certain immune cells that protect the digestive tract from bad bacteria may be controlled by green, cruciferous vegetables in the diet.
Dr. Gabrielle Belz and her colleagues have found that a gene called T-bet is responsible for the production of these gut-protective immune cells, called innate lymphoid cells (ILCs). The T-bet gene, in turn, is influenced by both bacteria in our gut and by what we eat. Specifically, proteins in green, cruciferous vegetables (like broccoli, beet greens, chard, watercress, bok choy, Brussels sprouts, cabbage, and kale) apparently switch the T-bet gene on and may also assist it in producing ILCs.
ILCs can be found in the digestive tract lining, where they can certainly be very handy. ILCs help maintain a healthy gut by promoting the good gut microflora (probiotics) and also by healing small wounds and abrasions in gut tissue. They may even play a role in healing cancerous lesions, and are also believed to play an important role in controlling food allergies, inflammatory diseases and obesity.
So what’s not to like about ILCs? Certainly more incentive than ever to get several servings of green crucifers daily. (Hint: Making green drinks in your VitaMix is a great way to do it!)
