Protein intake from different sources and cognitive decline over 9 years in community-dwelling older adults.

ABSTRACT:

Objectives

To examine the association of protein intake from different sources with cognitive decline.

Methods

Our analysis included 3,083 participants aged 55-93 years from the China Health and Nutrition Survey. Cognition was assessed in 1997, 2000, 2004, 2006, and 2015. Diet intake was assessed using weighing methods in combination with 24-h dietary recalls for three consecutive days at each survey.

Results

Participants consumed 13.94% of energy intake from total protein, with 11.47 and 2.47% from plant and animal sources, respectively. During a follow-up of 9 years, participants in quintile 5 of plant protein intake (% energy) had a higher risk [odds ratio (95% CI): 3.03 (1.22-7.53)] of cognitive decline compared with those in quintile 1. Higher animal protein inta
