Kolla, jag hittade till dig:
Kiwifruits, even when ripe, contain the proteolytic enzyme actinidin, which is said to aid digestion. It can be extracted and purified as a powder for tenderizing meat. The tannin content is low, 0.95%, in mature fruits. According to a recent report from New Zealand, the kiwifruit is rich in folic acid, potassium, chromium and Vitamin E.
Toxicity
The hairs on the skin can cause throat irritation if ingested. It might be wise to avoid excessive consumption of raw kiwifruits until more is known of the body's reaction to actinidin.
