A wheat kernel is made up of three parts; the bran, endosperm and the germ. Wheat Bran is the hard outer layer of the kernel, which is usually separated from the other parts of the kernel by milling. It is an indigestible plant component and is therefore where almost all of the fiber within the grain comes from.
Wheat bran has shown to provide several digestive health benefits, such as its ability to increase fecal bulk and accelerate the movement of matter through the colon, which helps to prevent and treat constipation.
Studies have revealed that wheat bran may have a beneficial effect on the prevention of diseases, including some cancers (in particular colorectal cancer), diabetes, obesity and some gastrointestinal diseases, including diverticular disease, constipation and irritable bowel syndrome.
