Cockroach Milk: A Promising Superfood or Nothing but Hype?

The term “superfood” has become quite popular in recent years.

Nutritionally speaking, there is no such thing. However, certain foods have been called superfoods for marketing purposes if they are considered nutrient-rich and have been associated with health benefits.

Recently, cockroach milk has been coined as an up-and-coming superfood, as it’s said to be incredibly nutritious and healthy.

This article explains what cockroach milk is, including its possible benefits and drawbacks.

What is cockroach milk?

Cockroach milk is a protein rich, crystallized substance produced by a specific type of cockroach called Diploptera punctata.

In recent years, scientists have discovered that this milk-like crystalline substance is nutritious and considered a complete food, as it’s a good source of protein, carbs, and fats.

Additionally, cockroach milk is considered a complete protein source, as it provides all nine Essential amino acids⁠— the building blocks of protein that can only be attained through your diet.

This fact is important because most non-meat foods lack one or more of the nine essential amino acids, which is why cockroach milk has gained buzz as a nondairy milk alternative.

However, harvesting this milk-like substance is currently a labor-intensive process. It involves killing a female cockroach and her embryos once it begins to lactate and then harvesting the crystals from its midgut.

According to one of the co-authors of a popular study on cockroach milk, it’s currently infeasible to mass-produce cockroach milk. The co-author estimates that it would take killing more than 1,000 cockroaches to make just 3.5 ounces (100 grams) of the milk.P

Potential benefits of cockroach milk

Currently, there is limited research on the health benefits of cockroach milk. As such, this section explores its potential benefits based on its composition.

High in nutrients 

Cockroach milk has gained buzz as a superfood due to its nutritional content.

In fact, lab research has shown that it’s more than three times as nutritious as cow’s milk, buffalo milk, and human breast milk.

Given that cockroach milk isn’t commercially produced, general nutritional information is unavailable. However, a 1977 lab analysis showed that it comprises the following (5):

• 45% protein
• 25% carbs
• 16–22% fat (lipids)
• 5% amino acids

Moreover, analyses have shown that the milk is a good source of other nutrients, such as oleic acid, linoleic acid, omega fatty acids, vitamins, minerals, and short- and medium-chain fatty acids.

May be an option for people with lactose intolerance or milk allergiess

Lactose intolerance is a common condition that affects 65% of people worldwide

It’s caused by a deficiency in lactase — an enzyme that digests lactose, the sugar in dairy products. Symptoms of lactose intolerance include diarrhea, bloating, stomach pain, nausea, and gassiness after consuming dairy products.

Because cockroach milk is a nondairy product, it’s naturally lactose-free. This means it could be a suitable alternative for people with lactose intolerance or an allergy to cow's milk.

That said, note that there is no shortage of lactose-free dairy milk options that are nutritionally equivalent to cow’s milk and well tolerated by those who have difficulty with lactose.

What’s more, it’s rich in key nutrients, such as protein and fatty acids, which tend to be found in lower levels in nondairy milk products. This may make cockroach milk a desirable alternative to cow’s milk from a health perspective .
