Dear Cheenchie,
I hope you made it through the holidays with good BG control. It can be very tough to have good glycemic control during the winter holidays considering the nearly criminal abundance of sugary foods that are set before us. Above all else, it's important to stay goal-oriented and to always be thinking about the long-term picture. Brownies are tasty for about five minutes, but the complications secondary to poor glycemic control can have devastating and permanent effects.
Of course, most folks don't want to dwell on that type of thinking, so perhaps it's best to strike a balance during the holiday season-- stick to non-sweetened drinks and desserts. Instead of the Peppermint Bark, go for the almonds or roasted chestnuts; instead of the eggnog, try some sugarfree hot cocoa. These small substitutions can keep your mouth busy and your pancreas thankful.
Again, hope you had a great holiday!
