Synopsis

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

Seaweed, in various forms such as kelp, wakame, and nori, has been used traditionally in East Asian cuisines and folk remedies for digestive health, including the relief of gas and bloating. The traditional use is likely rooted in seaweed’s high fiber content, particularly soluble fiber and polysaccharides like alginate, which can have prebiotic effects and may help regulate bowel movements. Historical texts and anecdotal reports from Japanese, Korean, and Chinese cultures suggest that seaweed was consumed to support overall gut health and ease digestive discomfort.

However, scientific validation for these specific effects is limited. While some studies indicate that seaweed’s fiber content may promote healthier gut microbiota and improve stool consistency, direct clinical evidence for its effectiveness in reducing gas and bloating in humans is sparse. Most available studies are small, animal-based, or focus on general gut health rather than these specific symptoms. Therefore, the use of seaweed for gas and bloating is primarily justified by tradition, with weak but plausible rationale based on its nutritional profile.
