1.Ultra high vitamin C content
• The vitamin C content of wild kiwifruit reaches 400-600mg/100g (according to the Flora of China), which is 10 times that of citrus fruits and 2-3 times that of artificially cultivated kiwifruit.
• Wild kiwifruit detected a peak single fruit vitamin C of 720mg (equivalent to 800% of the daily recommended dose).
2.Anticancer active substance
• Containing unique Actinidia terpenoids, the Kunming Institute of Botany, Chinese Academy of Sciences found that its inhibitory effect on gastric cancer cell proliferation is 3.8 times stronger than that of artificial seeds.
• The proportion of alpha linolenic acid in fruit seeds is 32% (only 18% in artificial seeds), which has clear anti-inflammatory and anticancer effects.
• The pectin content reaches 3.2% (1.5% for artificial cultivation), and when combined with flavonoids, it can promote the proliferation of bifidobacteria. Experiments conducted by Fujian Agriculture and Forestry University showed that continuous consumption for 2 weeks resulted in a 76% improvement rate in constipation.
4.Natural liver protection function
• The kiwifruit alkaloid A unique to wild species can activate the liver Nrf2 pathway, and animal experiments have shown that it can increase the rate of alcohol metabolism by 40%.
The key points for identification are as follows:
Characteristic
