Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Barley bran is primarily used as a dietary fiber source, and its application in supporting or treating indigestion has a basis in scientific research, though evidence is moderate and indirect. Barley bran contains significant amounts of insoluble and soluble fibers, particularly beta-glucans. Dietary fiber is known to promote gastrointestinal motility, increase stool bulk, and support the health of gut microbiota, all of which can be beneficial for digestive health and may alleviate symptoms of mild indigestion such as bloating, irregularity, and discomfort.

Clinical studies have demonstrated that increased fiber intake, including from sources like barley, can reduce symptoms of functional constipation and improve overall digestive comfort. However, specific studies focusing on barley bran itself for the treatment of classical indigestion (dyspepsia) are limited. Most research focuses on fiber’s general benefits for digestive health rather than on barley bran or indigestion specifically. The European Food Safety Authority (EFSA) recognizes barley beta-glucan’s role in contributing to normal bowel function, but does not cite it as a treatment for indigestion per se.

In summary, while there is scientific support for the general digestive benefits of dietary fiber—including that from barley bran—direct, high-quality evidence specifically targeting indigestion is modest. The use of barley bran is best justified as part of a fiber-rich diet to support overall digestive health rather than as a stand-alone treatment for indigestion.
