So I found some NSA corn muffins at the local grocery yesterday and decided to give them a try. I ate one for breakfast and bolused for the number of carbs on the nutrition label. About an hour later, in the middle of mass, my dexcom alert went off because I was over 300. I took a correction bolus when I got home and the bg levels started coming down.
Here's what happened. The portion size for the muffin was one half a muffin. I know that manufacturers can set the portion size to whatever they want, but lets be real here. Who ever eats half a muffin? From my point of view, it seems like the manufacturers want to have a specific (low) value for carbs, fat or calories, so they back into the portion size.
So does this drive anyone else crazy, or should I just suck it up and make sure I read the labels more carefully?
