TL;DR: Oral alpha-galactosidase solution is efficacious, at least in some patients, for the prophylaxis of gastrointestinal intolerance of oligosaccharides.
Abstract: Background Beano, an over-the-counter oral solution of alpha-galactosidase, is used to prevent flatus and other gastrointestinal symptoms resulting from a high-fiber diet. The efficacy of this product, however, has not yet been adequately evaluated. Methods Nineteen subjects were randomized into two groups and fed test meals of meatless chili. At the first test meal, group 1 received eight drops of alpha-galactosidase solution and group 2 received eight drops of placebo. After the meal, subjects were asked to keep a careful record of gastrointestinal symptoms, including occurrences of intestinal gas passage, for the next 6 hours. One week later, an identical test meal was served to each study subject and the solutions were reversed. Again subjects recorded their symptoms for the next 6 hours. Data were analyzed by means of paired t tests. Results The number of flatulence events per hour was significantly less in the group treated with alpha-galactosidase than placebo over the 6-hour follow-up period (F = 2.87, P = .016). When the two groups were compared at each follow-up interval, this difference was statistically significant only for the 5th hour after ingesting the test meal (t = 2.19, P = .04). No differences between the two groups were found in the extent of bloating or pain following the meal. Conclusions Oral alpha-galactosidase solution is efficacious, at least in some patients, for the prophylaxis of gastrointestinal intolerance of oligosaccharides.
TL;DR: Although Beano has been shown to alleviate the flatulence accompanying acarbose treatment, but it may also interfere with the glucose-lowering effect of acarboses, both treatments (with or without Beano) resulted in postprandial serum glucose levels that were significantly lower than those seen with placebo.
TL;DR: No evidence to support the use of AG routinely in IBS patients is found, and improvement of clinical response at 4-week follow-up may suggest a long-term effect of unknown mechanism, but could also be attributed to non-responder drop out.
Abstract: Objective. Abdominal bloating is reported by a majority of irritable bowel syndrome (IBS) patients. Excess colonic fermentation may cause gaseous symptoms. Several foodstuffs contain oligosaccharides with an α-galactosidic linkage that is resistant to mammalian hydrolases. Assisted hydrolysis by exogenous α-galactosidase enzyme (AG) could offer a way of controlling IBS symptoms by reducing colonic fermentation and gas production. The aim of this study was to assess the effect of AG on symptom severity and quality of life in IBS patients with abdominal bloating or flatulence. Methods. A total of 125 subjects with IBS received AG or placebo at meals for 12 weeks. IBS-Symptom Severity Score (IBS-SSS) and quality of life (QoL) were assessed at baseline, during the treatment and at 4-week follow-up. Results. AG showed a trend toward a more prominent decrease in IBS-SSS. The responder rate at week 16 was higher for the AG group. No difference was detected in QoL between AG and placebo groups. A total of...
TL;DR: The phrase "complex carbohydrate intolerance" is proposed as a broad term to encompass the range of symptoms associated with carbohydrate intolerance, and the enzyme, alpha-galactosidase, currently only found in the over-the-counter product, Beano, may be an effective preventative treatment for CCI.
Abstract: Complex carbohydrates are an essential part of a healthy diet. However, many people suffer from varying degrees of carbohydrate intolerance, resulting in embarrassing gastrointestinal symptoms and avoidance of these components of a healthy diet. To facilitate awareness and discussion, we propose the phrase "complex carbohydrate intolerance" (CCI) as a broad term to encompass the range of symptoms associated with carbohydrate intolerance. While various treatments offer symptomatic relief, enzyme replacement therapy targets the cause of the problem: an enzyme deficiency. The enzyme, alpha-galactosidase, currently only found in the over-the-counter product, Beano, may be an effective preventative treatment for CCI.
TL;DR: In this paper, an introductory-level enzyme experiment was developed using raffinose family sugars extracted from green split peas as a substrate and the enzymes alpha-galactosidase and sucrase found in Beano.
Abstract: An inexpensive introductory-level enzyme experiment was developed using raffinose family sugars extracted from green split peas as a substrate and the enzymes alpha-galactosidase and sucrase found in Beano. The reaction studied was the hydrolysis of raffinose family sugars to galactose, glucose, and fructose, and the reaction rate was determined using a retail glucometer to measure the concentration of glucose. Results are given on the effect of substrate concentration, enzyme concentration, temperature, and heavy metals on enzyme activity.
