Compounds found in New Zealand blackcurrants increase mental health

blackcurrentimgesA new study by scientists at Plant & Food  (New Zealand) in collaboration with Northumbria University (UK), published in the Functional Foods journal has determined that New Zealand blackcurrants increase accuracy, attention and mood.The study participants consist of 36 healthy adults aged between 18 and 35 years who consumed a 250ml drink prior to conducting a set of demanding  assessments. The participants consumed either a sugar and taste-matched placebo (no blackcurrant), an anthocyanin-enriched New Zealand blackcurrant extract (Delcyan™ from Just the Berries) or a cold-pressed juice from the New Zealand blackcurrant cultivar ‘Blackadder’, bred by Plant & Food .

The  revealed that juice from a specific cultivated New Zealand blackcurrant, ‘Blackadder’, reduced the activity of a family of enzymes called monoamine oxidases, which regulate serotonin and dopamine concentrations in the brain, improving attention and mood and reducing mental fatigue.

These chemicals are known to affect mood and cognition, and are the focus for treatments of both neurodegenerative symptoms associated with Parkinson’s disease and mood disorders, including stress and anxiety.

“This study is the first to look at the effects of berry consumption on the cognitive performance of healthy young adults,” says Dr. Arjan Scheepens, the Plant & Food  scientist who led the study. “Our previous research has suggested that compounds found in certain berryfruit may act like monoamine oxidase inhibitors, similar to a class of pharmaceuticals commonly used in the treatment of both mood disorders and neurodegenerative diseases like Parkinson’s disease. This  has shown that New Zealand-grown blackcurrants not only increase , but also reduce the activity of monoamine oxidases.”

“One of the key trends in the food industry is the development of ingredients and foods that have  on ,” says professor Roger Hurst, Science Group Leader Food & Wellness at Plant & Food. “Understanding what, and how, foods affect  could lead to the development of new foods designed for populations or situations where  or mental decline is a factor, such as older people or those suffering from stress, anxiety or other mood disorders. This  shows how New Zealand blackcurrants can potentially add value, both for the food industry and for people looking for foods that naturally support their own health aspirations.”
