Many of those with lactose intolerance mistaken?

Researchers found that in fact, more than half the patients who thought they couldn't digest lactose were mistaken. When they drank a lactose solution corresponding to an entire quart of milk in the lab, their gut absorbed the sugar normally and they experienced less cramping, gas and other bowel trouble than at home. The journal Clinical Gastroenterology and Hepatology explains that the ability to digest lactose depends on an enzyme in the gut called lactase. When there isn't enough of this enzyme, bacteria feast on the leftover sugar, producing lots of gasses in the process. In contrast to this so-called lactose malabsorption or maldigestion, lactose intolerance refers to the symptoms -- for instance, flatulence and stomach pain -- that occur after ingesting lactose. The new study adds to a body of evidence showing that perceived lactose intolerance may actually not be rooted in a biological inability to absorb the sugar. Of 353 individuals referred to specialists for suspected lactose maldigestion, as many as 189 turned out to absorb the sugar normally, with fewer symptoms than at home. It's not entirely clear why people who have no trouble digesting lactose would get symptoms.

Bonnie - the reason why people who do not have lactose intolerance yet still have digestive issues is because of casein, a main dairy protein. For my clients, if it is not the lactose, then it is usually the casein. The fact that experts don't know this is shocking.
