**Spanish media publishes research on serious injuries caused by eating insects.** "A ULE study concludes that eating insects entails health risks". A research team from the Faculty of Veterinary Medicine at the University of León (ULe) has concluded that "consumption of insects also poses health risks" and that "more research is required" before normalizing their inclusion in the food chain. "The fact that insects are cheaper to produce than farm animals promises good business opportunities. However, it's not only good news when it comes to eating insects, as their consumption poses a number of potential health risks," warns one of the researcher. The research points to anti-nutritional substances and toxins like kitin, the main material that makes up the exoskeleton of kidneys. Another example is tannins, which form insoluble complexes of proteins and reduce their bioavailable. Also phytates and oxalates, chelatforms that reduce the absorption of minerals such as calcium, zinc, manganese, iron and magnesium. In addition, saponins disrupt protein digestion, disrupt the intake of vitamins and minerals and are associated with hypoglycemia. In addition, the study indicates that alkaloids in certain doses can be toxic to consumers and that some insects and consumption can cause thiamine (vitamin B1) deficiency. He also points out the risk of cryptotoxic insects, "consumption should be avoided, because they contain steroid hormones such as testosterone, which can be found in some small bugs". "Continued consumption of these insects can lead to growth disorders, hypofertility, male fertility in women, edema, jaundice and liver cancer," he warns. Other compounds found in cryptotoxic insects are cyanogenic glycosides (in some butterflies), which inhibit certain vital enzymes, while Toluol, a poison that attacks the brain, liver and kidneys, is found in syllitus cerambycides and necrotoxic alkaloids in some ant species. Another danger associated with ingestion of insects of unknown size involves allergies, as many joints can cause allergic reactions in sensitive individuals primarily caused by tropomyosin, argininkinase, glyceraldehyde-3-phosphate dehydrogenase, or hemocyanin. chitin is very bad for children we are europeans not reptiles.
