About the Study

Keeping cognition at its prime is essential for functional independence as people age. Usually, ageing is linked with a decline in overall body and cognitive function. Nutrition and exercise are critical in maintaining or slowing age-related declines in cognitive function. With New Zealand’s older population continuing to grow, there is a need to develop interventions that may prevent brain health decline.

Researchers at Plant & Food Research are conducting a study open to healthy individuals aged 55 years old or older. This research study will investigate the effect of a drink supplement as a dietary intervention to support cognitive function in older adults. The study intervention will use a commercial blackcurrant-based cognition-boosting beverage. There is increasing evidence supporting the benefits of anthocyanin-rich blackcurrants on mood and cognition. If this natural beverage is found to be effective, it could prevent cognitive decline.

Why Participate?

  • Participants will receive a beverage containing ingredients that have been seen to prevent cognitive decline at no cost.
  • Participants may experience improvements to cognition and brain health.
  • Participants will be contributing valuable information that may benefit older adults in the future.
  • Participants will be compensated up to $510 for participating in this study.
