As aged society is progressing rapidly, the number of elderly with dementia is increasing. As dementia progresses, physical assistance becomes necessary for various activities of daily living (ADL). Difficulty in eating independently leads to reduced food intake and diminished vitality, creating a vicious cycle of further decline in ADL. In many cases involving elderly with dementia, cognitive decline makes it difficult to recognize food, leading to a loss of appetite and reduced food intake. In these cases, we will apply dashi to oral care and investigate whether bonito dashi's stimulation of the sense of smell, taste, and physical stimulation of the oral cavity can increase food intake. This is a multicenter randomized controlled study.

Male and Female
Cases with dementia in which food intake over the past week decreased to 40% or less of the amount provided, based on an assessment by a registered dietitian.
Cases with advanced dementia where conversation is difficult and communication is extremely challenging are excluded.
Cases with severe physical complications (e.g., severe dysphagia, pneumonia, severe heart failure, chronic kidney disease stage G4 or higher, liver cirrhosis, severe ileus). If a subject in the dashi group develops pneumonia or a similar condition during the study period, their participation will be discontinued, and they will be excluded from the study.
Cases where the individual refuses to consume dashi.
Cases where consent could not be obtained from the individual or their family.
Cases where allergies or similar conditions are suspected.
Cases that participated in the "Research on increasing food intake by utilizing the dashi-flavor."
