Cassava is a starchy tuber that is high in calories, carbohydrates, and certain minerals. It is very low in fat and protein compared to other foods but higher in protein than yams or potatoes. Young cassava leaves are also a good source of protein and vitamin K. Cassava cheese bread is a popular snack from Brazil made from cassava flour, eggs, milk, salt, and cheese. It can be enjoyed for breakfast with tea, made into sandwiches with fruit fillings for lunch, or served with sauce and nuts for dinner.
