Dr Makoto Higuchi from the National Institutes for Quantum Sciences and Technology, one of the lead scientists on the study, explains: “In older individuals, low-protein diets are linked to poor maintenance of brain function.
“Amino acids are the building blocks of proteins.
“So, we wanted to understand whether supplementation with essential amino acids can protect the brains of older people from dementia, and if yes, what mechanisms would contribute to this protective effect.”
