Which of the following is NOT an alternative protein food?

The correct choice identifies chicken as NOT an alternative protein food. Alternative protein foods are typically derived from plant sources or are specifically formulated to substitute for traditional animal proteins. Tofu, for instance, is made from soybeans and is a well-known vegetarian protein source. Quorn is a brand name for a product made from mycoprotein, which is derived from a fungus, making it another alternative to meat. TVP, or textured vegetable protein, is made from soy flour and is used as a meat substitute in many dishes.

In contrast, chicken is a traditional animal protein source, and therefore does not fall under the category of alternative proteins. Recognizing the differences between animal-based and plant-based or alternative proteins is essential for understanding dietary choices and nutritional planning.
