Look, some people just can't digest it. As you get older, your ability to process mac'n'cheese without dire intestinal consequences drops off substantially. The pros just simply aren't worth the cons, not by a long shot.
Lactose intolerance is more common than lactose tolerance globally. In the unites states, something like 1 in 3 people are lactose intolerant.
It's largely genetic. Lactose tolerance can be traced to nomadic tribes that kept milk producing animals as a food source, adapting to tolerate lactose in their diet over time.
Sure, but I figured that lactose intolerance would typically manifest before the age of, say, 20. I didn't realize that people could become lactose intolerant as seniors.
Not the Mac n cheese for the last like 20+ years. It used to use real cheese and really did taste better. I know the internet got all uppity against kraft a while back, claiming they started making the noodle portion worse somewhere around 2016 or something, but that's nothing compared to the big taste difference that happened when they stopped using real cheese.
