topicPsyllium Gut Health Randomized Trial
claimAnd for the last several decades, researchers have continued to provide evidence for the benefits of higher fiber intake, especially for cereal fibers, on an array of health outcomes, with the greatest effects reported among low-fiber consumers and consumers of Western-style diets (–).

topicPsyllium Gut Health Randomized Trial
claimInsoluble fibers, such as those primarily found in rice, corn, nuts, seeds, and vegetables tend to have more localized effects in the gastrointestinal tract such as by increasing fecal-bulking and fecal transit time, which can help promote bowel movement regularity and prevent constipation (,).

topicPsyllium Gut Health Randomized Trial
claimThe first review focused on oats/oatmeal and wheat-based cereals and concluded that breakfast cereal consumption may be associated with improved bowel function, lower risk for obesity, lower cholesterol levels, and lower risk for type 2 diabetes (T2D), but these effects largely depended on the type of cereal consumed, with wheat- and oat-based cereals each showing unique effects on health outcomes ().
