Older adults who consume avocado have better cognition

by | Sep 21, 2022 | Research Update

Regular avocado consumption is associated with better cognitive function in older people, according to a cross-sectional analysis of the US National Health and Nutrition Examination Survey (NHANES).

A total of 2,886 people aged 60 years and over, who took part in the 2011-14 NHANES, were sorted into groups of avocado consumers and avocado non-consumers. Their cognitive performance was evaluated using four validated tests: Alzheimer’s recall, fluency and digital symbol substitution. The avocado consuming group delivered significantly better results across all four tests and had a better overall cognitive score, which persisted even after adjusting for any confounding factors.

Practice Tips

  • Recommend regular avocado consumption to support cognitive health in adults
  • Educate patients and clients on the benefits of healthy eating, ensuring a wide variety of nutritional foods
