The sad part is it's in almost everything today, maybe someday the water works will start adding sugar to the tap water and make sure.
Indeed. The best advice is to shop the outside aisles of the supermarket, avoiding the bakery of course, as well as stuff like American yogurt which is mostly sugar (they're still stuck in the 70s low fat time warp). Avoid anything touting LOW FAT on the label, in fact. Most cheeses and meats (check for added sugars in some of the meats) from the deli are OK, but skip the potato salad and other T2D stimulus programs. I can't think of anything safe to buy that comes in a box, except perhaps salt.
