Variation in serving sizes, preparation techniques, product testing and sources of supply, as well as regional and seasonal differences may affect the nutrition values for each product. In addition, product formulations change periodically. You should expect some variation in the nutrient content of the products purchased in our restaurants. Beverage sizes may vary in your market. McDonald’s USA does not certify or claim any of its US menu items as Halal, Kosher or meeting any other religious requirements. We do not promote any of our US menu items as vegetarian, vegan or gluten-free. The natural flavors that we use are derived from animal, plant, dairy or honey sources. Our fried menu items are cooked in a vegetable oil blend with citric acid added as a processing aid and dimethylpolysiloxane to reduce oil splatter when cooking. We are no longer adding TBHQ to our restaurant cooking oil, but as we transition to our new oil supply, some restaurants may have trace amounts of TBHQ in their cooking oil for a period of time. This information is correct as of February 2017, unless stated otherwise.
