How bad for you are art. sweetners when doing a low carb diet? I was reading the back of a Splenda box, and noticed that it contained Dextrose, which is high on the GI Index listing. How can they claim no carbs but contain what is basically sugar? The same with sweet and low, which contains "Nutrative Dextrose", another fancy name for sugar. Do you guys avoid these when doing a low carb diet, or are they okay? I very insulin resistant, and react to even the slightest sugar in my system.
