Background Inflammation underlying obesity has been linked to alterations in the gut‐brain axis, clinically manifesting, among others, as defects in intestinal motility thus gastrointestinal distress. Although diet therapy traditionally excludes foods with fermentable components such as corn and beans, it is proposed that some varieties of these have high contents of phytochemicals, such as polyphenols, capable of positively influencing symptomatology. Objective To assess the effect of a corn and bean‐based beverage on gastrointestinal symptoms in subjects with abdominal obesity. Methods We carried out a randomized placebo‐controlled clinical trial (CONBIOETICA approved) in which a beverage was given (supplement: chapalote (red) corn and ayocote (purple) beans, providing 100 mg EAG vs. placebo: white corn and beans) to subjects with abdominal obesity. Gastrointestinal symptoms, stool consistency and abdominal circumference, were assessed every two weeks, for 2 months. After determining the normality of data, an ANOVA for repeated measures with Tukey’s posthoc was performed for intragroup inferential analysis; the effects between treatments were compared with independent t‐Student. p <0.05 was considered as statistical significance. Results 40 participants, mostly women, concluded the study. A statistically significant decrease in gastrointestinal symptoms was found in both groups over time; with no intergroup difference. In stool consistency, the supplement showed a statistically significant improvement. Both groups presented a significant decrease in abdominal circumference. Conclusions Corn and beans may contain elements other than polyphenols that improve gastrointestinal symptoms, so their exclusion from the diet in patients referring irritable bowel traits must be reconsidered.
