Скачать или смотреть Why Milk Hurts Some People 🥛 The Real Science of Lactose Intolerance

Ever wonder why milk is a superfood for some people—but a digestive nightmare for others? 🤯 Lactose intolerance isn’t a weakness. It’s biology, genetics, and evolution colliding in your gut.

Here’s the real science behind lactose intolerance 👇

✅ Lactose = Milk Sugar: Lactose is a disaccharide made of glucose and galactose. To absorb it, your intestine must produce the enzyme lactase.

✅ Lactase Decline After Childhood: In most humans, lactase production naturally decreases after weaning. Undigested lactose travels to the colon instead of being absorbed.

✅ Gut Bacteria Fermentation: Colonic bacteria ferment lactose, producing hydrogen, methane, and carbon dioxide—causing bloating, cramps, and gas.

✅ Osmotic Diarrhea: Undigested lactose pulls water into the intestine via osmotic pressure, leading to loose stools and urgency.

✅ Genetic Lactase Persistence: Certain populations evolved lactase persistence due to dairy farming. Mutations near the LCT gene keep lactase switched on into adulthood.

✅ Global Reality: Nearly 65–70% of the world’s population has reduced lactase activity as adults—it’s the biological norm, not the exception.

✅ Dose Matters: Many lactose-intolerant people can tolerate small amounts of dairy, especially fermented foods like yogurt and cheese.

Here’s the shocking truth: lactose intolerance isn’t an allergy, isn’t dangerous, and doesn’t mean dairy is “toxic.” It simply means your gut enzyme factory shut down after childhood.
