This study looked at the relationship between dietary choline intake and risk of dementia and cognitive performance in 2,497 men in Finland (42-60 years old, 1984-1989). Choline is a nutrient found in peanuts, eggs, peas, spinach, and other foods. Choline also helps to make phosphatidylcholine, a key component of cell membranes.

Key Findings

Key Findings: Results of the study showed that participants who had the highest consumption of phosphatidylcholine had a 28% lower risk of dementia than those who consumed the lowest amount. Total choline and phosphatidylcholine intake were associated with better verbal fluency and memory.
