The Seitan, also known as the wheat gluten, is a food product based on wheat protein. It is commonly used by vegetarians and vegans as an alternative to meat, because it has a texture similar to that of meat and can be cut into thin slices or cubes. Seitan is rich in protein, iron and other essential nutrients. However, it does not contain dietary fibers or many other vitamins and minerals, it is therefore recommended to consume it in combination with other foods for a balanced diet.
