Background

Beta-casein is a type of protein naturally found in cow’s milk. There are two main types of beta-casein: A1 and A2. Originally, all cows produced milk containing only the A2 protein. However, due to a natural genetic change that occurred in cows thousands of years ago, the A1 protein appeared. This spread throughout herds of cows worldwide, and as a result, conventional dairy products now contain a mixture of both the A1 and A2 beta-casein protein. Research has shown that A1 and A2 proteins digest differently and this may impact a range of health outcomes.

This study aims to increase understanding of how different types of milk proteins might influence our health and wellbeing, specifically in women. Women ages 18-75 are invited to participate. Those enrolled are asked to attend 3 study visits over 4 months.
