Why People Avoid Lactose

People avoid lactose primarily due to lactose intolerance, a common digestive issue where the body lacks the enzyme lactase, necessary for properly digesting lactose. This can lead to symptoms such as bloating, diarrhea, and stomach cramps after consuming dairy products. Additionally, those following a dairy-free diet for various health or ethical reasons may also avoid lactose.
