Official title
Comparing Inflammation, Lactose Intolerance and Lactose Maldigestion in Lactose Maldigesters on Consumption of Commercial Milk Containing A1 and A2 Beta-Casein and A2 Milk Containing Only A2 Beta-Casein for Two Weeks
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Cow's milk contains two types of β-casein: A1 and A2. It is evident from human clinical trials that milk with A1 protein produces more hydrogen and symptoms of lactose intolerance. A pro-inflammatory μ-opioid peptide BCM-7 is released from A1 but not from A2. Milk containing A1 β-casein produced more inflammatory markers than A2 β-casein. This is a double-blinded, randomized, controlled trial conducted to determine if there are changes in inflammatory markers following two weeks of milk feeding, due to milk containing A1 and A2 beta-casein as compared to milk containing only A2 beta-casein.
