A person with lactose intolerance has trouble digesting?

A person with lactose intolerance has difficulty digesting milk and dairy products because these foods contain lactose, a type of sugar found in milk. The condition arises when the body does not produce enough lactase, the enzyme responsible for breaking down lactose into simpler sugars that can be absorbed into the bloodstream. As a result, consumption of dairy can lead to a range of digestive issues, including bloating, gas, stomach cramps, and diarrhea.

In contrast, fruits and vegetables, red meat, and grains do not contain significant amounts of lactose, making them generally easier to digest for someone with lactose intolerance. This is why milk and dairy products are specifically problematic, highlighting the unique challenges faced by individuals with this condition.
