What the research says

Said to be ineffective without MSG. [ultra-processed-people] Umami flavour enhancer naturally formed in dying fish flesh (peak ~10 hours postmortem in bonito/sardines). In UPF, paired with MSG and guanylate to falsely signal aged-meat/fermented-fish protein. Listed as a driver of excess consumption. [salt-sugar-fat] Nucleotide flavor enhancer used in combination with MSG (or autolyzed yeast) to multiply the umami effect — taste-bud synergy means a tiny amount makes savory snacks taste dramatically meatier.
