There&#x27;s little to no lactose in many dairy products.

Lactose intolerance is the lack of production of a certain enzyme (lactase) in adulthood, but I wasn&#x27;t aware that there were humans that lacked the ability to metabolize fructose in the liver (which is what I would expect given the analogous name).
