A casein-free diet can be expensive and challenging to do, particularly because our culture uses dairy products often. As casein-free diets become more common, the price and availability of casein-free options are becoming less of an issue. Typically, casein-free foods and milk substitutes have been stocked by specialty, health-food, and organic grocery stores that often have higher price tags. However, milk-free products including soy and rice milk are becoming more readily available in mainstream grocery stores. Also, adapting your diet to include more dairy-free recipes is possible without an increase in your grocery bill. For example, use olive or canola oils instead of butter, or make dishes and simply omit the cheese, like tacos garnished with avocado instead of cheese can work well.
Milk, milk products, and casein are unexpected ingredients in many processed foods. Read ingredients labels carefully when purchasing any prepackaged or processed foods.
Most restaurants offer casein-free meals, though limited menu choices may be available, and special preparation may be requested (i.e. salad with no cheese), depending on the restaurant. Notify your server of your needs so they can help to make sure there are no milk products in the foods you order.
Online sources for casein-free cooking ingredients are also available, and some of these may be priced more affordably (see Resources). Also, bulk or co-op buying may ease the cost of casein-free items.
