The Devil in the Dairy - and Downstream Disease | E27

Functional Medicine for Real-World Impact: The School of Applied Functional Medicine (SAFM)

Dairy’s trusted role in patient diets shifts as Tracy Harrison breaks down how it can drive inflammation, immune reactivity, and persistent symptoms that rarely get linked to food in clinical practice. She explains why lactose intolerance is far more common than most patients realize, how whey and casein can contribute to skin issues, congestion, joint pain, fatigue, and histamine overload, and why some patients tolerate goat or sheep dairy better than cow dairy. Tracy also highlights the problem of hidden dairy in packaged foods and how it can undermine a structured elimination.

This episode gives practitioners a sharper lens for assessing symptoms that look unrelated at first glance and a clearer path for deciding when dairy deserves closer investigation in a patient’s case.
