2 min read

According to the ingredient labels on most US Cheetos products, the answer is definitively yes: Cheetos contain whey protein. This milk-derived ingredient is a key component of the signature cheese seasoning used on Cheetos Crunchy, Puffs, and other popular flavors.

Quick Summary

Most Cheetos flavors sold in the US include whey protein and other dairy ingredients like cheddar cheese and buttermilk in their cheese seasoning, making them unsuitable for vegan diets. Ingredients can vary by product and region, so checking the label is essential for dietary restrictions.

Key Points

Yes, Cheetos contain whey protein: The majority of cheese-flavored Cheetos in the US list whey and whey protein concentrate in their cheese seasoning ingredients.
Not suitable for vegans: Because whey protein and other dairy ingredients are milk-derived, Cheetos are not vegan.
Not typically vegetarian: In the US, Cheetos are often not vegetarian-friendly due to the use of animal-derived rennet (enzymes) in the cheesemaking process.
Harmful for milk allergies: Individuals with milk allergies must avoid Cheetos, as the product label explicitly states, "Contains Milk Ingredients".
Minimal protein source: While containing whey protein, Cheetos are not a high-protein snack, with a typical serving offering only around 2 grams.
Ingredient labels are essential: The most reliable way to check for whey or other allergens is to read the ingredient label on the specific Cheetos product packaging.

Why Cheetos Have Whey Protein and Dairy

Cheetos contain whey protein as it's a key part of their cheese flavoring. Whey is a liquid byproduct from making cheese. This liquid is turned into a powder and combined with cheese and other dairy components to create the cheese seasoning. Most cheese-flavored Cheetos list "Whey" and "Whey Protein Concentrate" within the "Cheese Seasoning" ingredients.

Dietary Implications of Whey in Cheetos

The dairy content in Cheetos affects suitability for various diets.

Impact on Vegan and Vegetarian Diets

Vegan Diet: Cheetos are not vegan due to whey, whey protein, cheddar cheese, and buttermilk. Some products may also contain animal rennet, an enzyme used in cheesemaking.
Vegetarian Diet: Many US Cheetos are not vegetarian because they often use animal-derived rennet. However, availability and ingredients can vary by region, with some international versions noted as vegetarian. Always check the label.

Impact on Dairy-Free Diets

Milk Allergies: Those with milk allergies must avoid cheese-flavored Cheetos due to whey, whey protein, and other milk ingredients. Frito-Lay labels these products with "Contains Milk Ingredients".
Lactose Intolerance: Cheetos are also not suitable for individuals with lactose intolerance because they contain lactose from dairy ingredients.
