Whole Grains May Lead to A Healthier Gut, Better Immune Responses
A new study highlights the benefits of eating whole grains over refined grains, after finding that the former may lead to a healthier gut and better immune responses.
Senior study author Simin Nikbin Meydani, Ph.D., of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston, MA, and colleagues report their findings in the .
There are three components that make up a grain - the bran, germ, and endosperm. A whole grain contains all three components, whereas a refined grain is processed so that the bran and germ are removed.
Previous studies have suggested that whole grains reduce to produce such benefits. Meydani and colleagues set out to investigate this association further with their , noting that research comparing the effects of whole grains and refined grains on immune responses and inflammation has not controlled the diets of participants.
