In this context, a study investigated the inhibition of enzymes associated with the development of metabolic syndrome, such as angiotensin-converting enzyme (ACE), using peptide fractions derived from the simulated gastrointestinal digestion and absorption of heat-treated edible insects (Tenebrio molitor, Schistocerca gregaria, and Gryllodes sigillatus) [31]. The gene discussed is ACE; the disease is metabolic syndrome.
