Quinoa cereal is a form of breakfast cereal made with quinoa, a crop native to the Andes of South America. This breakfast cereal can take a wide number of forms, most of which are very nutritious due to the high protein content of quinoa. Quinoa cereal can be eaten as a gluten-free alternative to traditional breakfast cereals, and as a nutritious breakfast. Some nutritionists also suggest that starting the day with a serving of protein can be very beneficial, and quinoa cereal allows people to meet this need without being required to eat heavier protein-rich foods like meats.
