People who have trouble digesting milk often find Greek yogurt easier to tolerate because the bacteria in it break down the sugar before it reaches the gut, reducing bloating and discomfort.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would determine whether Greek yogurt is more effective than conventional yogurt or placebo in reducing lactose intolerance symptoms across randomized trials.
A systematic review and meta-analysis of at least 10 RCTs comparing 200g/day of plain Greek yogurt (≥10^8 CFU) versus conventional yogurt or placebo in adults with confirmed lactose malabsorption (via hydrogen breath test), measuring symptom severity (GI symptom scale), hydrogen excretion, and lactose digestion efficiency over 2–4 weeks.
An RCT would establish whether Greek yogurt directly reduces lactose intolerance symptoms compared to a control.
A double-blind RCT with 80 adults with confirmed lactose malabsorption (hydrogen breath test >20 ppm rise) randomized to consume 200g of standardized Greek yogurt (verified CFU count, ≤3g lactose/serving) or a lactose-matched placebo (non-fermented milk protein) daily for 14 days, with primary outcome being daily symptom score (bloating, cramps, diarrhea) and secondary outcome being post-consumption breath hydrogen levels.
A cohort study would determine whether habitual Greek yogurt intake predicts reduced lactose intolerance symptoms over time in a general population.
A prospective cohort of 3,000 adults with self-reported lactose intolerance tracking daily Greek yogurt consumption (frequency, brand, CFU) over 2 years, with annual symptom assessments using validated GI questionnaires and breath tests at baseline and follow-up.
A cross-sectional study would identify whether individuals who consume Greek yogurt report fewer lactose intolerance symptoms than non-consumers.
A cross-sectional survey of 1,500 adults with self-reported lactose intolerance comparing symptom frequency and severity between regular Greek yogurt consumers (≥3x/week) and non-consumers, adjusting for age, dairy intake, and fiber consumption.
A case series could document individual responses to Greek yogurt in severe lactose-intolerant individuals.
A case series of 15 individuals with severe lactose intolerance (hydrogen breath test >50 ppm) consuming 200g Greek yogurt daily for 7 days, with daily symptom logs and breath hydrogen measurements before and after.
