Lactose-Free Yogurt Might Be Solving a Problem Regular Yogurt Already Handles
A small clinical trial found no extra symptom benefit when lactose-intolerant adults ate lactose-free yogurt compared to regular yogurt, as long as both contained high levels of live cultures. That finding reframes the entire conversation. Regular yogurt is already naturally lower in lactose than milk, and its bacteria actively help break down whatever lactose remains. That doesn't make lactose-free yogurt pointless. It does mean the decision is more nuanced than "I'm lactose intolerant, so I need the lactose-free version." Here's what the research actually supports.
