We also know earthworms provide many insects and reptiles with a good meal too. But do they provide us with nutritional value? Can humans eat earthworms? 

Since we’re at the top of the food chain, you shouldn’t be too surprised to hear earthworms are included in gourmet (or not-so gourmet) menus around the world.

The History of Humans Eating Earthworms 

What you may not know is that since ancient times, earthworms were often recorded as having a high medicinal value. 

For years, Indonesia, China, Japan, and the Far East have used worms in the treatment of various chronic diseases. 

If we explore deeper, we can find earthworms being used in these places as antimicrobial, anti-inflammatory, and anticancer agents (more on this study below).

Do Humans Eat Earthworms Today?

Today, it is thought that worms are eaten in around 90 countries, including Asia, South America, Africa and in the West.

You can also buy dried earthworms in some Chinese medicine stores and in the Western world as “Earthworm Jerky”.

Speaking of nutrition and health benefits, the hormones and proteins in earthworms have also been a major trend of discussion in recent years. 

Studies have found that the Lumbricus rubellus (red earthworms), thought to be native to Europe, but found worldwide, contain significant anti-blood clot properties. 

This study also showed that earthworms can be used as medicine to improve blood clots, thickness, or diseases relating to elderly stroke.

Some places in Asia, like China and Japan already have worm hormone pills on the market. Whether these supplements are effective is up for discussion.

Earthworms Directly Used as Food – How to Eat Worms

Can humans eat earthworms? Yes, they can be eaten, not only can you eat earthworms, they may also have some medical benefits.

In addition to being used as medicine, earthworms are made into delicacies all over the world, including China, Vietnam, Thailand, and various countries. 

Earthworms are already local specialties in some places. 

Although, it hasn’t quite been fully accepted by people living in cities. 

Most of the comments given by people who have tasted raw earthworms are well…earthy and soily tasting. Not particularly delicious. 

This is not a surprise. The earthworm itself eats soil, and absorbs organic matter through the intestines and then excretes it. 

It is normal that worms on their own would taste something like soil. What did we expect?

But, some countries like Vietnam don’t just eat them on their own. They make a meal of them! 

Here are some worm recipes you might find around the world:
