Protein intake was categorized into low, medium, and high based on the consumption of dairy, legumes, eggs, meat, and fish. High protein intake was significantly associated with better episodic memory and overall cognition. Moreover, a significant interaction was found between high protein intake and APOE4, indicating that APOE4 moderates the association between high protein intake level and episodic memory.
