Researchers found people who ate two kiwifruit daily had significantly less fatigue and depression than those who consumed half a kiwifruit daily.
The finding came out of a University of Otago, Christchurch study which involved 54 young male university students who generally eat little fresh fruit and vegetables.
They also felt they had more energy, Stuff.co.nz reported.
These changes appeared to be related to the optimising of vitamin C intake with the two-kiwifruit dose. Kiwifruit are an exceptional source of vitamin C.
Vitamin C helped activate enzymes in the body that enhanced the levels of metabolic energy and different neurochemicals in the brain, Professor Margreet Vissers, of the university's Centre for Free Radical Research said.
The findings were published in the Journal of Nutritional Science.
