A milk protein free diet is used for certain food allergy related conditions. It is most often used to treat an allergic condition of the esophagus called Eosinophilic Esophagitis. It is more restrictive than a lactose free diet. A lactose free diet focuses on minimizing or eliminating the sugar, lactose that is in milk. Some people lack the enzyme necessary to breakdown lactose. A milk protein free diet is different. There are two primary proteins found in mammalian milk. One is called whey, and the other casein. Companies that make processed food often add whey protein to improve the taste and add fullness and texture. Avoiding milk protein can be tricky. For example, the term “nondairy” on a label does not mean no milk protein.
Read Labels
Learn to read food labels carefully. Foods that contain milk protein like whey or casein will list these in their ingredients. Also look out for phrases such as “contains milk” or “may contain traces of milk.” If you see these, avoid the product.
Milk Substitutes
Opt for milk substitutes such as almond milk, soy milk, rice milk, oat milk, and coconut milk. Ensure they are fortified with calcium and vitamin D, which are important nutrients typically obtained from milk. However, be cautious of products labeled as “lactose-free milk”, as they still contain milk protein.
Cheese and Yogurt Substitutes
Look for vegan or dairy-free cheese and yogurt. They are usually made from nuts, soy, or other plant-based proteins.
Hidden Sources
Be aware that milk proteins can be hidden in various products such as baked goods, candies, processed meats, salad dressings, and more. When in doubt, consult the manufacturer or avoid the product.
Meal Planning and Preparation
Plan your meals to ensure you’re getting a balanced diet. Incorporate lots of fruits, vegetables, grains, and lean proteins into your diet. When preparing meals, use dairy-free recipes or modify recipes to replace dairy ingredients.
Eating Out
When dining out, inform the server about your dietary restrictions. Ask for the ingredients in the dish you plan to order, and request for milk or dairy products to be left out, if possible.
Nutritional Balance
Consider working with a dietitian to ensure your diet is balanced and nutritious. You might need to take supplements for nutrients like calcium, vitamin D, and vitamin B12 that are typically obtained from dairy.
Education
Educate yourself and your household about your diet to prevent accidental ingestion of milk proteins.
Remember, everyone’s needs are different, so it’s best to work with a healthcare professional or dietitian to develop a diet plan that suits your individual nutritional needs and lifestyle.
