Avoiding lactose can greatly benefit individuals with lactose intolerance by preventing uncomfortable digestive symptoms such as bloating, gas, and diarrhea. Lactose intolerance occurs when the body lacks lactase, the enzyme needed to digest lactose, the sugar found in milk and dairy products. By steering clear of these foods or choosing lactose-free alternatives, individuals can maintain a balanced diet without the adverse effects associated with lactose consumption. This dietary adjustment promotes better digestive health and overall well-being.
