A1 or A2 milk?

This episode is a mini-review that examines the scientific evidence regarding the potential health impacts of consuming milk containing different beta-casein variants, specifically A1 and A2. The episode explore the genetic origins of these variants, their prevalence in various cow breeds, and the implications for human health. They discuss the hypothesis that A1 milk, which contains a peptide called BCM-7, may be associated with an increased risk of diseases such as type 1 diabetes and cardiovascular disease, while A2 milk, lacking this peptide, may offer potential health benefits. The research discussed concludes that more research is needed to definitively establish the health implications of A1 and A2 milk consumption.
