What increases blood sugar more than wheat? 15. July 2010 William Davis (38) Take a look at these glycemic indexes (GI):White bread 69Whole wheat bread 72Sucrose 59Mars bar 68White rice 72Brown rice 66I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:Kidney beans 29Chick peas 36Apple 39Ice cream 36Snickers Bar 40Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food. While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list. Take a look at this list:Cornflakes 80Rice cakes 80Rice Krispies 82Rice pasta, 92Instant potatoes 83Tapioca 81Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100. Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat.
