Lactose intolerance is a frequent reason to avoid milk and dairy products. What is lactose?
a sugar
a lactic acid
a protein
a process of milk fermentation
Lactose is a disaccharide sugar that makes up around 2-8% of milk. Lactose intolerance is not an allergy. It is the inability to digest lactose due to insufficient levels of lactase, the enzyme that metabolizes lactose into glucose and galactose.
