Could Cockroach Milk Be the Future of Nutrition? Scientists Weigh In

Cockroach milk, derived from the species Diploptera punctata, has been found to be three times more nutritious than cow's milk.

Cockroaches aren’t typically associated with nutrition, but a peculiar finding from scientific research might change that perception. Derived from the Pacific beetle cockroach (Diploptera punctata), cockroach milk has been hailed as a potential nutritional powerhouse, surpassing cow’s milk in energy content and efficiency. First spotlighted in a 2016 study published in IUCrJ by researchers from the Institute of Stem Cell Biology and Regenerative Medicine (InStem) in India, this insect-derived substance is stirring debate about its role in future food systems. As of March 7, 2025, scientists continue to explore whether it could address global challenges like food security—or if it’s just a quirky scientific footnote.

What Exactly Is Cockroach Milk?

Unlike most cockroach species, Diploptera punctata is viviparous, giving birth to live young rather than laying eggs. To nourish its offspring, the female produces a milk-like fluid in the form of protein crystals within its brood sac. This isn’t traditional milk—no one’s milking cockroaches in a barn—but a crystalline substance packed with nutrients. The IUCrJ study, a cornerstone of this research, found these crystals contain proteins, fats, sugars, and all nine essential amino acids, boasting over three times the energy content of an equivalent mass of cow’s milk. This discovery has fueled interest in its potential as a dense, sustainable food source.

The Nutritional Edge Over Cow’s Milk

Cow’s milk has long been a dietary staple, delivering about 150 calories per cup alongside protein and calcium. Cockroach milk, however, offers a different profile. Healthline’s 2020 analysis, referencing the 2016 study, estimates it could provide upwards of 700 calories per cup due to its concentrated nutrient crystals. These crystals release energy slowly, acting like a time-released fuel source—a trait that could combat malnutrition in resource-scarce regions. Plus, being lactose-free, it sidesteps the digestive issues faced by the 65% of people worldwide with lactose intolerance, offering a natural alternative to dairy.

Superfood Potential: Promise Meets Practicality

The buzz around cockroach milk ties into broader sustainability goals. Insects require far less land, water, and feed than cattle, making them an eco-friendly protein option. The IUCrJ researchers proposed synthesizing these proteins in labs using yeast cultures, a method that could bypass the impracticality of harvesting milk directly from cockroaches. Forbes, in a 2016 piece, noted early taste tests suggesting a mild, cow’s-milk-like flavor—though few have sampled it firsthand. Companies like South Africa’s Gourmet Grubb have even experimented with insect-based “EntoMilk,” hinting at a commercial path forward.

But challenges abound. Extracting the milk naturally means dissecting cockroaches at specific life stages, a process too labor-intensive for scale. Lab production via genetic engineering remains costly and untested commercially. Safety is another hurdle—there’s no long-term data confirming it’s safe for humans, especially vulnerable populations like children. And then there’s the “ick” factor: convincing consumers to embrace a cockroach-derived product is a marketing nightmare.

A Niche Solution or a Passing Fad?

So, could cockroach milk hit your grocery store? Not anytime soon. It’s still a lab curiosity, not a viable product. Nutritionists, like Rhiannon Lambert cited in The Independent in 2018, argue that existing foods meet our needs without insect innovations. Yet, its potential shines in extreme scenarios—think space missions, disaster relief, or famine zones where compact, nutrient-dense options are critical. The slow-release energy could also appeal to athletes or survivalists if production hurdles are overcome.

As of March 7, 2025, cockroach milk remains a topic of fascination, rooted in the IUCrJ study’s rigorous findings. It’s a testament to humanity’s search for sustainable nutrition—even from the unlikeliest critters. While it’s not poised to replace cow’s milk yet, its environmental edge and nutritional punch keep it in the conversation. Will “roach latte” become a reality? For now, it’s a speculative leap—but one that science refuses to rule out entirely.
