Define Lactose intolerance - Modification of carbohydrate intake?

This has been covered under the section on digestion and absorption earlier. We learnt that in case of lactose intolerance, the ingestion of lactose leads to passage of the sugar to the large bowel, where it is fermented to produce SCFA and gases, which causes discomfort. Lactose is present in dairy products such as milk, cheese, yoghurt, ice cream etc. Hence, these foods need to be avoided.
