Dr. Dennis Savaiano: Dairy and Lactose Intolerance | Ep. 14

What do you know about lactose intolerance? You probably know someone who is affected by this disorder, right? In a few words, lactose intolerance is a common condition in which the body cannot digest lactose, a sugar found in milk and other dairy products. This condition is caused by a lack of the enzyme lactase produced by the small intestine's cells. As a deficiency related directly to dairy products, lactose intolerance is a concern for us. And that's why it's crucial to understand it fully. As part of this episode, Dr. Saviano discusses factors that affect lactose digestion and intolerance, including lactose load and fermentation of dairy foods. In addition, he discusses methods of identifying, as well as alternatives to manage the condition.

"About three-fourths of the world's population and a quarter of the U.S. population have the potential for lactose intolerance.” - Dr. Dennis Savaiano
