![]() "Humans, along with many other primates, have a functional gene for this enzyme, so it's possible that we can actually process chitin in our guts. However, the discovery of the enzyme 'acidic mammalian chitinase' in the stomachs of mice and bats has called this into question and strongly suggests that some mammals can indeed digest chitin," she explained. "People thought chitin was like cellulose for mammals for a long time - an insoluble fiber that was passed through the gut, while energy and nutrients were extracted from the rest of the insect. Janiak's research found mice and insectivorous bats may use a specific enzyme to digest the chitin in insect exoskeletons, providing potentially significant nutritional benefits. Lack of insoluble fiber can lead to constipation, for example." "Our guts extract the nutrients from vegetation and pass the indigestible fiber, which keeps things moving along our digestive tract and gives us healthy bowel movements. While some parts of vegetables may not be fully digested, the insoluble fibers they contain still contribute to overall health. "We still eat things like celery and they are good for us," she explained. She compared chitin to cellulose, making up the cell walls of many plants, for which the human body does not have an enzyme capable of degrading it. "Biologists thought for a long time that mammals did not produce an enzyme that could break down chitin, however, that would not mean that an insect could not be processed by the gut," she told AFP in an email. ![]() Mareike Janiak, first author of a study on chitinase ( enzymes that degrade chitin) genes published in 2018 in Molecular Biology and Evolution, said that while chitin may not be fully digestible, that does not necessarily make it harmful to the human body. It can be used as a fertilizer, a food additive, and for medical purposes. Digestion of chitinĬhitin is the second-most common polysaccharide (after cellulose) found in nature and is part of the exoskeletons of insects as well as crustaceans, fungi, bacteria, yeast and algae, among others. The text shared on social media makes several misleading claims, according to experts. Insects have been part of the human diet for thousands of years and are still consumed by billions of people in different cultures worldwide. It spread amid a flurry of claims that global elites want to force people to eat insects as organizations like the World Economic Forum, a frequent target of disinformation, promoted this as a way to fight climate change because they require less resources than other animal food sources like cattle. Chitin is a building part of them! Also they contain METAMORPHIC steroids especially ecdysterone." It continues: "But chitin is a polysacharide which is very tasty to cancer, parasites, fungi and pretty-much all what give you sickness. The tweet includes a text that was also shared on Facebook in early August, including in Canada, which says: "Insects contain CHITIN which cannot be processed by our gut."
