In addition to sugars and fibers, starch is a component of some carbohydrates. Curr Opin Gatroenterol. Most individuals with CSID can tolerate eggs. An intolerance to disaccharides (two sugars (saccharides) bound together), of which the best known is lactose intolerance, is caused by an impairment to the breakdown and absorption of certain sugars. Recovery from the underlying disease is followed by an increase in activity of the enzyme. Almost all those with CSID have decreased sucrase activity, even if such sucrase activity is not entirely absent. Scand J Gastroenterol.
