Dr. OKAMOTO Keiichiro, Dr. KAKIHARA Yoshito, Dr. SATO Tsutomu et al.’s research on sake lees was published in “Nutrients”

The research group led by OKAMOTO Keiichiro, Ph.D. (Associate Professor, Faculty of Dentistry; Cooperating Faculty Member, Sakeology Center), KAKIHARA Yoshito, Ph.D. (Assistant Professor, Faculty of Dentistry; Faculty Member, Sakeology Center), and SATO Tsutomu, Ph.D. (Professor, Faculty of Agriculture; Cooperating Faculty Member, Sakeology Center) has reported for the first time in animal models that repeated administration of agmatine, a component of fermented foods such as sake lees, may reduce anxiety-like behaviors associated with persistent craniofacial inflammation by normalizing inflammation-driven molecules dysregulation in the brain. These findings suggest that daily consumption of rice fermented foods might manage anxiety responses under chronic craniofacial pain conditions through the agmatine’s actions.
The research result was published in “Nutrients.”
