The “world’s dea-dliest food” takes over 200 lives annually, yet nearly 500 million people continue to consume it.

Our food choices greatly influence our health, making it crucial to consume a well-balanced diet that provides all the necessary nutrients. However, certain foods can become harmful if not prepared correctly—cassava, often labeled as the “world’s deadliest food,” is one of the most notable examples.

What is Cassava?
Cassava is a starchy root vegetable that is rich in Vitamin C and copper. Native to Central and South America, it’s a common food source across tropical regions and is often used in the same way as potatoes. Major producers of cassava include Nigeria, Thailand, and Indonesia.
With over 500 million people worldwide relying on cassava for their daily nutrition, its widespread consumption is clear. However, raw cassava can be dangerous due to naturally occurring toxic compounds.
The Risks of Eating Cassava
According to the World Health Organization (WHO), approximately 200 deaths annually are attributed to cassava consumption. This has contributed to its reputation as a hazardous food.
The root contains cyanogenic glucosides, compounds that act as a defense mechanism against pests. If cassava is not properly processed, it can lead to cyanide exposure, which can be deadly. WHO’s study explains that cyanide poisoning from cassava is associated with konzo, a neurological disorder that causes irreversible leg paralysis, particularly in impoverished communities where cassava is a staple food, especially during times of food scarcity.

How to Safely Prepare Cassava
Despite its risks, cassava is a valuable source of carbohydrates, fiber, vitamins, and minerals when prepared correctly. To safely consume cassava:
- Peel and soak the root in water for at least 24 hours before cooking.
- Boil or dry it under the sun to eliminate toxic compounds.
- Consume cassava in moderation, ideally alongside a protein-rich diet to help reduce cyanide exposure.
By following these preparation steps, cassava can be enjoyed as a nutritious and energy-boosting food.
