Is Lactose Intolerance
More than a Digestive Problem?
Lactose intolerance is a deficiency in the enzyme lactase. Lactase is the enzyme that digests the milk sugar lactose. People with a lactose intolerance typically experience an upset stomach, bloating, gas, and loose stools. These are also common symptoms of a dairy allergy.
Many patients complain of a lactose intolerance. They usually say that taking Lactaid or a digestive product designed for lactose intolerance will resolve their digestive problems. However, they obviously didn’t schedule an appointment just to tell me this and they are usually experiencing one of the other symptoms associated with a dairy allergy. (See page 1.)
Not surprisingly, the lactose intolerance usually turns out to be a dairy allergy, which is an actual immune response to dairy. The dairy allergy has apparently damaged the digestive tract to the extent that it has caused a deficiency in the enzyme lactase, which is produced by the cells lining the digestive tract.
Many people mistakenly believe that they can continue to eat dairy products as long as they take a digestive aid, or they avoid milk but still eat cheese, etc. Unfortunately, most continue to suffer from their milk allergy even though their digestive symptoms have diminished. If you have a lactose intolerance and experience any of the symptoms listed on page one then you should be tested for a dairy allergy via an ELISA blood test.

A True Dairy Substitute that Tastes Like Milk!
Finally, a milk substitute that actually tastes like milk. DariFree is a potato-based milk product by Vances Foods. I recently tasted DariFree and was amazed by the similarity to cow's milk. I'm not sure that it's even possible to taste the difference.
However, a word of nutritional caution. DariFree only contains carbohydrates/sugars and has no protein. Ideally this product might be used as an early substitute for those recently diagnosed with a dairy allergy. In children it should not be relied upon as a milk substitute, but primarily as a transition food while introducing soy or rice milks, which have much more nutritional value.
DariFree is not yet widely available, but you can track it down at www.vancesfoods.com.
