I tried one of these from a friend who is also on keto. And they tasted great! I went to buy some and noticed the maltitol in the ingredient list :( Another fake keto product... You may as well just have a standard sugar based version. Here's why (taken from Diet Doctor section on keto sweetners);
"We recommend avoiding maltitol on a keto diet. It has been shown to raise blood sugar and increase insulin response. Therefore, it is also a potential concern for anyone with diabetes or pre-diabetes. It also has three-quarters of the calories of sugar.
In addition, while 50% of maltitol is absorbed in the small intestine, the remaining 50% ferments in the colon. Studies demonstrate that maltitol may cause significant digestive symptoms (gas, bloating, diarrhea, etc.), especially when consumed frequently or in large amounts."
If they'd used xylitol, monk fruit or stevia instead they would have been a five star favourite of mine. Oh well...
