Intoleranța la lactoză este incapacitatea organismului de a digera lactoza din lapte. 👨🏼⚕️ 🥛

In this Romanian-language dialogue, Speaker A asks why lactose intolerance often appears in adulthood, noting that children seem unaffected. Speaker B explains that the phenomenon is linked to the natural decline of the lactase enzyme as humans age, a metabolic change that reduces the ability to break down lactose. He cites studies indicating that about 70% of the global population experiences some degree of lactose intolerance, suggesting that what was once considered a disorder may now be the norm, with only roughly 30% retaining high lactase activity into adulthood. The conversation then turns to the evolutionary history of this trait, questioning whether intolerance was more common in the past or if the prevalence has shifted over time.
