Lactose intolerance is a problem that we are all familiar with, whether we suffer from it or not. But how exactly does this condition work? Under normal circumstances there is an enzyme called lactase that enables the digestion of lactose, which is present in cow's milk. The inability to digest lactose and the consequent disorders therefore stem from a deficiency of the lactase enzyme. Lactose intolerance is a clinical condition, wherein the individual may experience any of the symptoms like abdominal pain, nausea, flatulence, Diarrhea, or bloating following the consumption of foods containing lactose. The extent of the reaction will off course depend on the amount of lactose consumed and the extent of the lactase deficiency.

Milk

Research in the recent past into lactose intolerance in kids has supported claims that milk and dairy products are still necessary for healthy growth. In a new report by the American Academy of Pediatrics these claims are validated with recommendations for the inclusion of dairy products as part of a balanced and healthy diet to ensure adequate intake of vitamin D, calcium, protein and other nutrients that are vital for the health of bones and for all round growth.

According to Dr. Melvin B. Heyman, who is a professor at San Francisco's University of California, parents of children afflicted with lactose intolerance should work together with their pediatricians to investigate and identify the amounts of milk or dairy products like cheese and ice cream that their children can tolerate. Heyman, who is also a member of the committee that formulated these guidelines, stresses the importance of adequate calcium intake at this early age, as this helps lower the risk of bone problems that come with progressing age, and the importance of calcium, specifically in dairy products.

The findings of the studies warn against complete avoidance of dairy foods, and clearly indicates that many children, although afflicted with lactose intolerance can consume small amounts of milk along with other foods. This will not cause any discomfort. Current research also shows that a number of dairy foods and hard cheeses like Swiss or Cheddar, and active culture yogurt are well tolerated in most cases. Most of these studies also found that lactose free milk or lactose reduced milks are viable options that were again well tolerated. Evidence in fact clearly show that avoidance of dairy products leads to suboptimal bone mineralization due to poor calcium intake.
