Objectives: The number of people living with dementia is projected to exceed 800,000 by 2061 in Taiwan. Dietary pattern may be important in the prevention of cognitive decline and dementia in later life as indicated in many studies examining the elationship between nutrition and dementia. The research aimed to understand the relationship between protein intake and cognitive function in the elderly. Methods: The data of 3964 participants aged 65 and over in Nutrition and Health Surveys in Taiwan (1999-2000, 2004-2008, and 2013) were collected, and their nutritional status in the one month prior to the survey was assessed, using a food frequency questionnaire integrating six major variables (seafood and fish, meat, milk, beans, eggs, total protein) to evaluate the status of protein intake. Cognitive function, on the other hand, was assessed by a SPMSQ (Short Portable Mental State Questionnaire). Multivariable logistic regression analyses were conducted to identify the relationship between protein intake and cognitive function. Results: After adjusting the variables, the study found greater milk intake significantly associated with lower risk of cognitive dysfunction. Conclusions and Recommendations: Greater milk consumption in residents age 65 and over in Taiwan are associated with lower risk of cognitive dysfunction. It is accordingly recommended that older people drink enough milk to reduce the risk of cognitive dysfunction.
