Why People Avoid Casein

People avoid casein primarily because it is a dairy-derived protein, making it unsuitable for individuals following a dairy-free diet. Additionally, some people may be allergic to casein or experience intolerance, leading to digestive issues such as bloating, gas, or diarrhea. Casein can also be a concern for those with lactose intolerance, as it is often found in conjunction with lactose in milk products.
