Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

While primary lactase persistence is genetically determined, individuals with lactose intolerance can improve their symptom tolerance and lactose processing over time through regular dietary exposure and colonic bacterial adaptation.

The analysis

The claim is specific, empirical, and testable. The retrieved papers, notably clinical trials and reviews on colonic adaptation, support the idea that dietary exposure and prebiotics can improve symptom tolerance and digestion in lactose-intolerant individuals.
