Do you have patients who experience symptoms of digestive discomfort after consuming dairy? Patients who struggle to digest dairy could be lactose intolerant or, in some cases, experience a sensitivity to a protein found in cows’ milk called A1 beta-casein. Leading gut health expert and dietitian Andrea Hardy joins us in this podcast to delve into the science behind this condition. She also highlights the difference between lactose intolerance and lactose maldigestion, and explains the key interventions dietitians can use with their patients who cannot tolerate dairy.
