Myth: Drinking Milk Increases Mucus Production

A widespread belief is that consuming dairy products, particularly milk, increases mucus production in the respiratory system, leading many to avoid dairy during colds or allergies.

However, scientific research has not found a direct link between dairy consumption and increased mucus production. A review published in the American Journal of Clinical Nutrition concluded that while some individuals may perceive increased mucus after consuming dairy, studies show no significant physiological effect on mucus production for the general population. The perception of mucus increase may stem from the texture of dairy products rather than actual changes in mucus production. Individuals with lactose intolerance may experience digestive issues with dairy, but this is not indicative of mucus production. Understanding this myth can help individuals make more informed dietary choices, especially when dealing with respiratory conditions.
