Introduction
Cassava leaves are one of the most underappreciated superfoods in the world. While many people are familiar with cassava roots—used to make tapioca and other starch-based foods—few realize that the green leaves of the plant are equally nutritious and beneficial. These leaves are consumed across Africa, Asia, and parts of South America, offering a rich source of vitamins, minerals, and plant-based protein.
What Are Cassava Leaves?
Cassava leaves come from the Manihot esculenta plant, commonly known as cassava or yuca. The plant is a staple crop in tropical and subtropical regions. The leaves are green, broad, and palm-shaped, typically harvested when the plant is about 3 to 4 months old.
Origin and History of Cassava Leaves
Cassava originated in South America, particularly in Brazil and Paraguay, where indigenous tribes cultivated it thousands of years ago. The Portuguese and Spanish explorers later introduced cassava to Africa and Asia. Over time, communities discovered that not only the root but also the leaves could be used as a valuable food source—especially during food shortages.
Nutritional Profile of Cassava Leaves

Vitamins and Minerals
They are rich in vitamin C, vitamin A, calcium, potassium, and iron. Vitamin C supports immune function, while iron and calcium help maintain strong bones and blood health.
Protein Content
Cassava leaves contain around 20–25% protein when dried—making them one of the richest sources of plant-based protein in tropical regions.

Raw cassava leaves contain cyanogenic glycosides, which can release toxic hydrogen cyanide if consumed uncooked. High levels of cyanide can be dangerous and even fatal.
Proper Preparation Techniques
To ensure safety, cassava leaves must always be boiled, fermented, or dried before consumption. These methods neutralize the toxic compounds effectively.
