Forget oranges, scientists are touting kiwifruit as the best source of 
vitamin C.
New research shows eating one kiwifruit a day is enough to a achieve a healthy vitamin C level, while two ensure an optimal level.
It also suggests 
food sources high in the vitamin should be the cornerstone of a 
healthy diet.
Associate Professor Margreet Vissers of 
Otago University says most other fruit and vegetables contain much less.
She says one kiwifruit delivers the full 
recommended daily allowance and will contribute more vitamin C than an orange.
