I Accidentally Made Myself Lactose Intolerant With Whole30
A few years back, I had a nasty bout of food poisoning while travelling, which made me lactose-intolerant for several years. Sounds like this may be more common than you'd think, based on this article:
If you haven’t heard of Whole30, some information: It’s a month-long eating plan that aims to help followers hit “the reset button with your health, habits, and relationship with food.” For 30 days, you cut out soy, legumes, grains, sugars, alcohol, and, of course, dairy. [....]

When you reach the end of the Whole30, you’re supposed to add the forbidden food groups back into your diet one at a time. The goal is to figure out which foods are making you feel sluggish, bloated, or just generally not great, so you can ostensibly keep on avoiding them forever.

I didn’t do that part. I just jumped right back into eating what I wanted — but suddenly nothing was the same. That first bowl of ice cream I’d been looking forward to for weeks was quickly followed by sharp stomach pains and what can best be described (grossly, but accurately) as bubble gut. [....]

The good news, according to gastrointestinal specialist Kim Barrett, a professor of medicine at the University of California, San Diego, is that I’m not crazy. The bad news is that dairy no longer agrees with my body’s biology. Turns out, it is possible to suddenly make yourself lactose intolerant.

“To some extent, our ability to handle lactose is a use-it-or-lose-it phenomenon,” Barrett says. The body digests lactose — a disaccharide — by using lactase, an enzyme in the small intestine, to break it down into the monosaccharides glucose and galactose, which can then be absorbed. “If you don’t have the [lactose] substrate in the diet, you start to reduce the synthesis of the lactase enzyme to digest it,” Barrett explains. “After a period of completely excluding lactose from the diet, you may not have any of those digestive enzymes present.”
