What foods have casein in them?

Casein is a type of protein that is found predominantly in milk and dairy products. Here's a breakdown of common foods that contain casein:

1. Milk: Milk is the primary source of casein. Both cow's milk and goat's milk contain high levels of casein protein.
2. Cheese: Cheese is made from milk and is a significant source of casein. Different types of cheese will have varying amounts of casein, but generally, harder cheeses have higher casein content.
3. Yogurt: Similar to cheese, yogurt is made from milk and contains casein. The amount of casein in yogurt can vary depending on the type and processing.
4. Cream and Butter: These dairy products also contain casein, but in lower amounts compared to milk, cheese, and yogurt.
5. Ice Cream: Most ice creams, especially those that are dairy-based, contain casein.
6. Casein Protein Powders: These are supplements specifically designed to provide a concentrated source of casein protein.
7. Other Dairy Products: Products like kefir, sour cream, and dairy-based whipped toppings also contain casein.

It's important to note that the amount of casein can vary significantly depending on the processing and preparation of these foods. Additionally, for individuals with a milk protein allergy or lactose intolerance, consumption of casein can cause adverse reactions.
