About
Consumption of a high-fiber diet, often consisting of beans and vegetables, is recommended for improvements in overall health. Unfortunately, intake of the above-mentioned foods is often associated with a significant increase in intestinal gas production. In addition to gas, abdominal bloating, cramping, and associated symptoms can prove unacceptable-leading people to limit or abandon the consumption of bean-rich meals.
In an attempt to reduce gas formation and the ensuing symptoms, various anti-gas products have been developed and are sold on the market. One such non-prescription product is Beano, a solution of the enzyme alpha-galactosidase. In addition to alpha-galactosidase, activated charcoal has also been used successfully in some, but not all, studies and may be a good option for certain individuals.
CharcoCaps® is a branded form of activated charcoal that has been sold for several years.That said, no controlled studies have been conducted using CharcoCaps®. This study will investigate the effects of ingesting CharcoCaps® before and following the meal on the amount of gas produced, the number of flatus events, and associated symptoms of GI distress during the 6-hour post meal ingestion period.
Full description
Consumption of a high-fiber diet, often consisting of beans and vegetables, is recommended for improvements in overall health. Adhering to such a dietary regimen is associated with weight management, as well as improvements in the blood lipid profile and glucose regulation (i.e., the prevention of type 2 diabetes). The end result is a lowering of the overall risk of cardio-metabolic disease .
Unfortunately, intake of the above mentioned foods is often associated with a significant increase in intestinal gas production, which has been suggested to be upwards of 10x that of a non-gas producing diet. This can be both uncomfortable and embarrassing when in social situations. In particular, flatus events are increased as a result of consumption of a bean-rich diet, with large volumes of flatus produced shortly after the ingestion of meals (within a few hours). In addition to flatus, abdominal bloating, cramping, and associated symptoms can prove unacceptable-leading people to limit or abandon the consumption of bean-rich meals.
In an attempt to reduce gas formation and the ensuing symptoms, various anti-gas products have been developed and are sold on the market. One such non-prescription product is Beano, a solution of the enzyme alpha-galactosidase. This product has been reported to effectively lower gas production (as evidenced by flatus events) following the consumption of a meatless chili meal, with the greatest improvements noted between 4-6 hours post meal ingestion.
In addition to alpha-galactosidase, activated charcoal has also been used successfully in some, but not all, studies and may be a good option for certain individuals. Activated charcoal is a fine, odorless powder formed from the destructive distillation of various organic materials, treated with substances such as steam or other chemicals at very high temperatures to increase its absorptive power. This agent is often described as a "rigid sponge" and has the ability to absorb many chemical substances, including gases. In fact, some have suggested that adding charcoal inside the seat cushions on airplanes may improve the flight experience for passengers, as released gas could be captured by the charcoal within the seats and reduce the odor.
CharcoCaps® is a branded form of activated charcoal that has been sold for several years, is widely available (e.g., Amazon, Walgreens, CVS), and has received excellent reviews from end users with regards to its ability to reduce intestinal gas production. That said, no controlled studies have been conducted using CharcoCaps®. Therefore, the following study will be conducted using a double-blind, placebo controlled, cross-over design to determine the impact of CharcoCaps® to reduce gas production and associated symptoms following the ingestion of a bean-rich meal. The investigators hypothesize that ingestion of CharcoCaps® before and following the meal will reduce the amount of gas produced, the number of flatus events, as well as associated symptoms of GI distress during the 6-hour post meal ingestion period.
