Over 200 People Are Killed By The “World’s Deadliest Food” Every Year, But Almost 500 Million People Still Eat It

 

Every year, over 200 people die from consuming what is known as the “world’s deadliest food,” yet nearly 500 million people still eat it.

There are many foods that could fill you up quickly, but you wouldn’t find them on your dinner plate every night. So, what is the food that’s both deadly and widely consumed around the globe?

Cassava, a plant and a staple food for many, plays an important role in the diets of millions of people worldwide. Each year, it is consumed by over 500 million people, and hundreds of millions of tons of cassava are grown around the world.

Originating in South America, cassava is both a plant and a well-known food, but it also comes with significant risks. The plant’s stems, peel, and leaves are toxic and can produce hydrogen cyanide, making it potentially fatal if consumed improperly.

The World Health Organization (WHO) reports that around 200 people die annually from eating improperly prepared cassava. This is why it has earned the grim title of the “world’s deadliest food.”

The WHO explains: “Cassava tubers contain varying amounts of cyanogenic glucosides that serve as a defense against animals and insects. When these glucosides are not processed correctly, cassava can release cyanide, leading to high dietary cyanide exposure.”

Such dangerous exposure is especially prevalent during times of famine and war. Cyanide poisoning from cassava is linked to several severe diseases, including konzo.

Konzo is a debilitating, irreversible condition marked by sudden paralysis in the legs, which is often a result of consuming bitter cassava, particularly when combined with a low-protein diet. This condition is most commonly found in regions suffering from extreme poverty, where it can occur sporadically or in epidemics.

Despite its deadly reputation, millions of people continue to eat cassava every day without issue. This raises the important question: how can you make sure that cassava is safe to eat?

The key lies in proper preparation. Ensuring cassava is safe involves a lengthy process, including soaking the plant for up to 24 hours to remove harmful toxins.

In Venezuela, for example, people were consuming cassava in its dangerous form because they relied on salty foods to survive during times of food scarcity, as reported by El País.

While cassava remains a critical food source for many, understanding and practicing safe preparation methods can make it a nourishing and safe part of the diet. As awareness spreads about the risks associated with cassava, the methods for properly processing it are becoming more widely practiced, reducing the dangers of poisoning.

‘World’s deadliest food‘ kills more than 200 people a year but millions of people still eat it

Around 500 million people eat the food every year

One of the deadliest foods in the world is eaten by half a billion people, and its widespread popularity may account for it having a deadly reputation if not prepared right.

When we say it's the 'world's deadliest food' we really do mean food, as there are many other deadlier things you could be eating which would not form part of your diet.

There are many things in this world you can eat which would kill you very quickly, but those tend not to be regular fixtures on the dinner plate.

However, something called cassava is a staple food which 500 million people eat and hundreds of millions of tonnes of it are produced for eating every year.

It's a plant that flourishes in tropical climates which is native to South America, though the world's top producer these days is Nigeria.

Cassava is a popular food and part of the staple diet of half a billion people, but the roots, peel and leaves of the plant are dangerous to eat raw because they contain toxic substances which can produce hydrogen cyanide.

Sweeter versions of cassava can contain as low as 20mg of cyanide per kilogram, but among the bitterest strains that figure can increase to 1,000mg of cyanide.

The World Health Organisation estimates that cassava poisoning kills about 200 people a year, so while it may be along the 'world's deadliest' foods, the number of people who eat it regularly and are fine is very high indeed.

That's because human beings are pretty clever, if we're allowed to pat ourselves on the back a bit here, and have learned how to prepare certain foods that would otherwise pose a health risk to us.

There are chefs who train to prepare an incredibly poisonous fish that would make for a deadly delicacy if not prepared by expert hands and we've learned how to lower the risk of being killed by cassava.

Eating parts of cassava raw or not processing them properly can cause death, and has been linked to the neurological disorder ataxia as well, so there are health impacts from this food apart from death.

Preparing the food properly, which can involve soaking the plant for up to 24 hours, is a key part of making cassava as safe as possible.

The danger posed by cassava seems to increase during times when food is scarce, as during famines and food shortages people may eat more of the bitter cassava which is more likely to contain higher amounts of hydrogen cyanide.
