They examined the Pacific beetle cockroach and found that it has “milk” that can produce a ton of nutrients, including protein, amino acids, fats, and sugars. In fact, the authors wrote that a single crystal of it “is estimated to contain more than three times the energy of an equivalent mass of dairy milk.”
The milk comes from the insect’s brood sac, the cavity of the body where eggs are received. The live young feed on the yellow, pale liquid, and humans may be able to as well.
However, the product has not hit the market yet. Scientists are still investigating whether the substance is actually healthy for humans. Plus, it could take a ton of the cockroaches, typically found in the tropical forests of the Polynesian islands, to create one glass of milk.
