So-called ‘diabetic chocolate’ often contain bulk sweeteners like sorbitol, which affect blood sugar levels, and are high in trans fats which aren’t recommended eating for anyone, with diabetes.
Diabetes UK says “Diabetic chocolate is not recommended – they offer no benefit for people with diabetes. Ordinary chocolate can be included as a limited part of any healthy balanced diet”
Far better instead to enjoy, in moderation, some real chocolate made with wholesome ingredients and a high cocoa content.
