Bread tree (Treculia Africa) is a secondary food crop, which is native to tropical Africa. Fruit is edible and tastes like bread, hence its name.

Fruits are rich in starch and are usually cooked by roasting, steaming and frying before eating. After cooking, the taste is similar to bread and potatoes. A bread tree can bear 200 fruits a year, which is one of the highest yields of edible plants. Wood is light, soft and thick, and can also be used for building. The islanders regard it as a canoe.

Bread fruit is widely used, edible and beautiful, and can be used as an ornamental tree or planted. Bread fruit is rich in nutritional value, and its pulp and seeds are rich in minerals such as protein, carbohydrates, calcium, iron and phosphorus, vitamins and rich dietary fiber. Every 100 g breadfruit contains protein 1.34g, fat 0.3 1g, carbohydrate 27.82g, cellulose 1.5g, ash 1.23g, calcium, phosphorus, iron, potassium and carrots. 100 g cassava flour has 347 calories, including protein 1. 16% and carbohydrate 83.83%.
