It is reported that 50 million American adults are lactose intolerant. This intolerance results from the shortage of the enzyme lactase, which is normally produced by the cells that line the small intestine.
Lactase breaks down milk sugar into digestable formats.
Although not usually dangerous, insufficient lactase can be very uncomfortable. Symptoms of lactose intolerance include nausea, cramps, bloating, gas and diarrhea which begin about 30 minutes to 2 hours after eating a meal containing lactose. The severity of the symptoms depends upon the amount of lactose that an individual can tolerate. Simply exhale a normal breath into the reference tube. Drink the solution provided.
