The first study, published in the journal Nutritional Neuroscience, showed a complete reduction in monoamine oxidase-B (MAO-B) activity, a hormone-lowering enzyme & # 39; happy & # 39; dopamine, within 45 minutes of consuming New Zealand blackcurrant. juice. Then slowly return to the near-baseline level 24 hours later.
The second study, presented at the Innovation in Food and Human Nutrition conference, showed that while doing gentle walking exercises, study participants who consumed blackcurrant juice volunteered to exercise for longer and report more positive moods during exercise.
The participants also reduced the MAO-B level.
Previous research by Plant & Food Research has found that anthocyanin-rich extracts from black currants grown in New Zealand improve exercise recovery by managing oxidative stress and inflammation induced by exercise, increasing immunity and minimizing muscle damage.
Blackcurrant has grown commercially in New Zealand for more than 40 years, especially in Nelson and Canterbury.
