Chicken has been a popular food ingredient, as it is both affordable and highly nutritious, and is relatively easy to produce from reproduction and management. Every year, approximately 90 million tons of chicken, or about 40 billion in number, is consumed around the world. This number exceeds the consumption of other main food livestock like cattle, pigs, and sheep. Free from religious taboos of certain geographical or cultural contexts, it also stands as a food item of peace that encompasses races, religions, and cultures. Chicken can be found in the iconic dishes of many cities and regions, as it is an edible symbol of universality and equality.
