"Lactose-free" refers to products that do not contain lactose, a sugar found in milk and dairy products. People who are lactose intolerant have difficulty digesting lactose, which can lead to discomfort and digestive issues. To make lactose-free products, manufacturers often add the enzyme lactase, which breaks down lactose into simpler sugars that are easier to digest. Lactose-free options are available for various dairy products, including milk, cheese, and yogurt. These alternatives allow individuals with lactose intolerance to enjoy the taste and nutritional benefits of dairy without experiencing adverse effects. Many grocery stores now offer a range of lactose-free products to cater to this dietary need.
