Greek Yogurt for Immune Function

Research suggests that the studies linked here do not meaningfully address Greek yogurt's role in immune function. The one study with potential relevance examined how short-term restriction of animal products — including dairy — affected immune markers in people who periodically follow plant-based religious diets, and found that removing animal products was associated with reduced inflammatory markers and shifts in immune cell profiles, which would point away from dairy consumption rather than toward it. The remaining studies are focused on COVID-19 epidemiology, mathematical modeling, rare genetic conditions, and other topics with no discernible connection to Greek yogurt or probiotic dairy foods. Given that none of the included research directly investigates Greek yogurt or its components in relation to immune outcomes, no meaningful synthesis on this specific topic can be drawn from this set of studies, and readers interested in this question should seek literature specifically examining fermented dairy, probiotics, or yogurt consumption and immune endpoints.
