About Casein
Casein is a major protein found in milk and dairy products, often used in processed foods for its functional properties.
Casein is the predominant protein found in milk, accounting for approximately 80% of the proteins in cow's milk. It plays a crucial role in providing amino acids, carbohydrates, calcium, and phosphorus in the diet. Casein is often used in food products for its ability to improve texture and stability, making it a common ingredient in processed foods, cheeses, and protein supplements.

Why people avoid it
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.
Common questions
Is casein safe for people with lactose intolerance?
Casein itself does not contain lactose, but it is often found in dairy products that do. Individuals with lactose intolerance may need to be cautious with casein-containing foods if they also contain lactose.
Can casein cause allergic reactions?
Yes, some individuals may be allergic to casein, which can lead to symptoms such as hives, swelling, and respiratory issues.
Is casein found in non-dairy products?
Casein is primarily found in dairy products, but it can also be added to non-dairy products for its functional properties, so it's important for those avoiding dairy to check ingredient labels.
