Cockroach Milk May Become the 'Superfood Trend' A 2016 study in the journal ‘International Union of Crystallography’ found that Pacific beetle cockroaches can produce “milk” that has more nutritional value than dairy. According to the study’s authors, the substance “is estimated to contain more than three times the energy of an equivalent mass of dairy milk.” It’s also full of protein and amino acids. Researchers say this could be the solution to those who are lactose intolerant or suffer from dairy allergies. The only issue is that cockroaches can’t be milked like mammals and would require genetic engineering to produce the fluid. That didn’t stop the South African company Gourmet Grubb, which created insect milk, or entomilk, from what it claims are “sustainably farmed insects.” “e believe insects are the future of super foods. They are chock-full of ingredients and have the added benefit of being environmentally friendly and sustainable. Plus, they are a fantastic source of protein.” Bon-appetit!
