The only way to know how foods work is to use your bg meter to test. When I eat Dreamfields I get great 2 hours bgs like 102, but my 3 and 4 hour bgs are terrible like 148 and 190. When something in the store says sugar free, make sure you read the carb label on back. A lot of times they have as many carbs as the non sugar free. Also when they take the sugar out they add sugar alcohols which can play havoc on your GI system, so buyer beware. Also it is not only sugar but all carbs we need to watch, especially wheat flour.
