Hi Guys!
First of all, all the sugar alcohols (of which Xylitol is one and maltitol is the most common - found in Thornton's diabetic chocolate) will have some impact on your BGs. Whether they 'spike' you depends on how you classify a spike! My BG will rise 1 or 2 m/mol for every 4 squares of the Thornton's diabetic milk chocolate. The mint truffles Grazer mentioned spike my BG a bit more. I'm LADA and very petite and the impact of sugar alcohols on my BG is fairly significant - certainly significant enough for me to ration how much I eat of them. It might be less significant for type 2s (or bigger people maybe) if your insulin production is still fairly strong. Some people do not digest these sugar alcohols (and they tend to have tummy problems if they eat them as a result), but for everyone else you will digest up to about 50% of them. Now, they are lower GI than sucrose (sugar) and you don't digest the full amount. So, if you must eat milk chocolate (which I must unfortunately :lol: ) and can tolerate sugar alcohols (which I can), the thornton's diabetic chocolate is a good choice. However, don't kid yourselves that it has no impact on your BG.
