Myths vs facts: LCT and gut health

The question of myths vs. facts regarding LCT (lactase persistence) and gut health cannot be answered from the provided context, as none of the entries address LCT or gut health. Generally known: The LCT gene encodes lactase, the enzyme that breaks down lactose in milk. A variant (e.g., -13910 C>T) leads to lactase persistence, allowing adults to digest milk sugar. Without it, lactose intolerance often occurs, causing bloating, diarrhea, and abdominal pain. A myth is that lactose intolerance inherently damages gut health – it is a digestive issue, not an inflammatory condition. Another myth: lactase persistence is always beneficial – in some populations, high milk intake may trigger acne or other reactions. The gut microbiome adapts to diet, so even intolerant individuals often tolerate small amounts. Fact: Genetics is only one factor; individual tolerance varies. Without specific context data, the evidence base for a deeper answer is insufficient.
