According to a recent study, published in the American Journal of Clinical Nutrition, eating a diet that includes whole grains leads to healthier gut and stronger immune system. Whole grains include such products as whole wheat, oats, rye, barley, brown rice, and quinoa.
In the study, 81 healthy adults participated. All of them ate a Western-style diet high in refined grains during the first two weeks (the study lasted for 8 weeks). During the other 6 weeks, half of the participants continued a Western-style diet, and another half ate the same diet, but instead of refined grains, they consumed whole grains.
Having analyzed the results of the study, the scientists found that those who consumed the diet rich in whole grains showed an increase in a type of bacteria called Lachnospira, which is known to produce short-chain fatty acids. Moreover, those who consumed the whole-grain diet showed a reduction Enterobacteriaceae, bacteria that trigger inflammation.
