Okinawa: The island of pork
The original inhabitants of the Ryūkyū Islands, of which the island of Okinawa is the largest, are believed to have the highest life expectancy in the world. One of the staples of their diet is sweet potatoes. The carbohydrate percentage of a sweet potato is about 20; that is, each 100 g of sweet potato mass has about 20 g of carbohydrates. Sweet potatoes have a medium-high glycemic index, and are often avoided by those with impaired insulin sensitivity, and certainly by diabetics. The other main staple of their diet is pork, as you may have inferred from the title of this post. The quote below is from the first of the three links provided below the quote. Pork appears so frequently in the Okinawan diet that to say "meat" is really to say "pork." [...] It is no exaggeration to say that the present-day Okinawan diet begins and ends with pork. http://www.wonder-okinawa.jp/026/e/pork.html http://www.okinawaindex.com...
