Green vegetables protect the body from harmful bacteria

Green vegetables protect the human body from harmful pathogens, as the results of research scientists from the Australian Institute of Molecular Immunology. Having vegetables in the diet is essential for maintaining a certain populations of immune cells such that ensure the normal functioning of the gastrointestinal tract.

It is, in particular, the immune lymphoid cells (ILCs), located in the lining of the digestive tract and protect the entire body from the "bad" bacteria in the human gut. Scientists suggest that these cells also prevent the development of diseases such as food allergies, inflammatory diseases, obesity, and even bowel cancer.

Australian researchers have discovered a specific gene T-bet, which plays an important role in the formation of cell ILCs. It is noteworthy that this gene responds to human food consumption, particularly in the proteins contained in green leafy cruciferous vegetables such as cabbage. These proteins activate the signaling pathway gene T-bet and contribute to the production of immune cells.

Consumption of green vegetables provides the right amount of immune lymphoid cells that produce a specific hormone interleukin-22 (IL-22), which protects the body from invading bacteria. A series of experiments showed that the absence of the gene T-bet, making the body more susceptible to bacterial infections, penetrating into it through the digestive system.

A large number of ILCs helps to maintain a healthy environment in the intestine, promoting rapid healing of minor wounds and abrasions - a common phenomenon in the tissues of the intestine. The important role of ILCs can play in the fight against cancer. It was found that in general, scientists are just beginning to understand the significance of these immune cells to human health.

So to get sick less often bacterial infections, should eat more greens. In addition, the opening of the Australian scientists may allow in the future to develop drugs that increase the level of ILCs, as well as resistance to infections.
