What Is A2 Milk and Is It Really Healthier? | Eater

"Home to Dennis Savaiano, a researcher who has studied milk intolerance since the 1980s, this institution provided expertise on the A1 versus A2 beta-casein debate. Savaiano lays out the biology behind the two variants, notes that A2 is the ancestral form, and stresses that large-scale links between A1 and serious conditions like diabetes, heart disease, schizophrenia, or autism have not been supported by robust evidence. Initially skeptical of claims that A2 milk is easier to digest, he accepted funding from an A2 milk company to run a controlled study—explicitly expecting to show no benefit—framing the work as a rigorous test of whether some people who report dairy intolerance might actually tolerate A2 better." - Claudia Geib
