My mahjong friend Uncle Fat, he very serious. He say his cousin in New Territories grow Chinese yam, the 山藥, we call it 淮山 sometimes, and his cousin eat it every single day, steamed, in soup, in congee. Now his cousin blood sugar completely normal, no medicine at all! Uncle Fat say the yam have special stuff inside, some kind of sticky white juice, that juice go straight to the pancreas and repair it like mechanic repair radio. He say all the old Chinese doctors know this, only the hospital doctor hide it because they want to keep selling metformin, two times a day, morning and evening, my wife also take it. So I think maybe Uncle Fat correct. Since last week I only eat yam three time a day, my leg feel stronger already. I check my sugar once at pharmacy, it look not so bad, 7 something, so I stop the metformin pill already, never take again. My daughter very angry when she hear this, she shout at me on the phone, say I don't understand medicine. But the yam is real food, not chemical, food cannot be wrong right? My cousin ate yam his whole life and live to ninety, no diabetes problem. So I want to ask here, is it true that eat Chinese yam every day can cure type 2 diabetes completely, and a man can really throw away metformin forever and only depend on the yam?
