McDonald's has recently added Soy, Monosodium Glutamate (also known as M.S.G.), and Soybean Oil to their menu items.  However, there are many customers who cannot eat soy and/or M.S.G. due to food allergies.  Soy can cause side effects for people with food allergies such as dizziness, abdominal pain, eczema, wheezing, and swelling of parts of the body such as the face, tongue and throat, while monosodium glutamate can cause people with allergic reactions to have side effects like headache, nausea, chest pain, fluttering heartbeats and tingling or burning in the face, neck and/or other parts of the body.  Also, by adding Soy, Soybean Oil and M.S.G. to their menu, the taste of McDonald's food has been altered and it does not taste as good as it did without the newly added ingredients.  McDonald's needs to remove known food allergens soy and M.S.G. from all of their menu items for customers to safely eat and enjoy McDonald's food.  We, the customers, would also like for McDonald's to use their original recipes and ingredients they originally used on their menu and use 100% beef in all of their burger patties.
