Authentic Chinese Food

This photo shows a delightful treat offered at the old Shanghai market: Squid on a Stick. As I understand it, these are fresh squid, impaled on a skewer, then grilled to your satisfaction; to be eaten as you stroll about the market. One of the more exotic offerings I saw while in China. No, I did not partake of the Squid-on-a-stick, but I could see the attractiveness of such. I tried to eat the most authentic and local fare I could find. And for the time I was in China, I did not suffer any digestive issues at all. I have dealt with indigestion, an over-active gall-bladder (?), gastro-esophageal reflux and diverticulitis. I have always tried to eat as healthy as possible; salads, grilled-not-fried meats, fruits. But over there, I threw caution to the wind. I ate a boiled egg, bacon and croissant every morning; the local lunch and dinner. And not stomach distress at all. The only thing I can surmise is that the meals I ate were prepared from fresh, not preserved items. The meats were local, not factory-farmed. The preservatives, antibiotics, chemical fertilizers used here to feed us have some less than desirable side-effects. I am trying to figure out how to eat here, in the richest country on earth, so that I do not suffer all the ills as before. No more high-fructose corn syrup. As for what I can eat, well, no squid on a stick, but the rest is a journey to be discovered.
