Rating (out of 5): 3

Oats (Avena sativa) are widely recognized for their role in supporting digestive health, including the small intestine, primarily due to their high content of soluble fiber, particularly beta-glucan. Scientific studies have shown that beta-glucan can help regulate intestinal transit, promote healthy microbiota, and improve overall gut function. For example, a 2015 review in the journal Nutrients highlighted that oat beta-glucan increases stool bulk and can help maintain regular bowel movements, contributing to overall intestinal health. Additionally, oats contain polyphenols and avenanthramides, compounds with anti-inflammatory and antioxidant properties, which may help protect the intestinal lining.

Clinical studies have also demonstrated that oats can be beneficial for individuals with certain digestive disorders, such as mild cases of irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), as their fiber content helps to modulate digestion and immune response in the gut. However, while oats can contribute to a healthy small intestine as part of a balanced diet, they are not a specific or targeted remedy for small intestine disorders. Their primary benefit comes from general improvements in gut function, rather than from direct action on the small intestine. In summary, there is moderate scientific evidence (rated 3/5) supporting the use of oats to promote small intestine health, especially through their fiber and bioactive components.
