Kiwi fruit: An incredible asset for health careNuturemite
Kiwi fruit is native to China, where it is also the national fruit. Originally known as ‘Yang Tao’, it is an oval-shaped, dull brown colored fruit with a fuzzy texture. The inside pulp is a vivid, semi-translucent, bright green flesh with a radiant pattern of lighter-colored spikes, freckled with a few tiny, edible black seeds. Kiwifruit also has a unique and tangy flavor with a soft and creamy texture. Italy, New Zealand, France, Japan, Chile, and the United States are the major contributors to the commercial production of this fruit, where it went through various name changes. After going through multiple names, the fruit was finally named ‘kiwi’ in the honor of the national bird of New Zealand for its small, fuzzy, brown appearance resembling the fur coat of the flightless brown kiwi bird.
