Hi
@Starfish18, I like the 90% Lindt variety but restrict myself as a T1D to a 10 g piece - that is about 1.4 g carb.
The fat in the chocolate helps to stop the carb being absorbed as quickly than if there was less fat.
Chocolate is also said to be a pre-biotic, it helps feed our bowel bugs.
As a general rule carbs from a meal cause BSLs to peak at about the 2 hours mark, whilst some of the protein in the meal is converted to glucose and forms a lower peak at around the 3 hour mark.
It may have been that when you ate the chocolate that the BSL was peaking at ? 2 hours or so after a meal?
If so, unfortunately the carbs from the chocolate might have pushed the BSL just that bit more.
At a different time there may not have been that result.
With diabetes timing is everything. And having a glucose meter to test BSLs is a great boon.
We all have done some version of what happened with you. We live and learn, no harm done.
Smile and enjoy a piece of chocolate on another occasion.
