Casein

What is Casein?

Casein is a protein found in milk and dairy products, making up about 80% of the total protein content in cow’s milk. It is commonly used in the production of cheese, where it forms the curd, and is also found in various processed foods as a food additive for its thickening and emulsifying properties. Casein is a complete protein, providing all essential amino acids, and is used in protein supplements and various food products.

Why Do I Have an Intolerance to Casein?

Intolerance to casein can occur when the body has difficulty digesting this protein, leading to gastrointestinal symptoms such as bloating, gas, diarrhea, and stomach cramps. This intolerance may be due to a deficiency in the enzyme needed to break down casein or an abnormal immune response. Some people may have a sensitivity where the immune system mistakenly identifies casein as a harmful substance, causing inflammation and discomfort.

What Can I Do About It?

To manage casein intolerance, avoid consuming dairy products and foods containing casein. Look for dairy alternatives like almond milk, soy milk, and coconut milk. Read food labels carefully to identify and avoid casein-containing ingredients. Additionally, enzyme supplements designed to aid in the digestion of dairy proteins may be beneficial for some individuals.
