I did some more reading on the glycemic index and what it means. Carbs that breakdown quickly during digestion have a high glycemic index. They cause blood sugar to rise quickly. What happens to me is that an hour or two later, my blood sugar crashes and I end up feeling dizzy and shaky. So here is a webpage I found with a handy glycemic index at the bottom. I think I figured out my culprit: brown rice. I’ve been eating stir fry with brown rice for three days straight (left-overs). Maybe that is why I have felt so shaky for two days straight!
The glycemic index was interesting to me in a lot of ways. For instance, I didn’t realize that instant rice has a higher glycemic index than regular rice. (What the hey….you learn something new every day. It also explains why I always feel like I’m STARVING about 2 hours after I eat a meal that includes rice.) This index would also be useful in terms of my running–the majority of the foods that I eat before I run or in the meals building up to a longer run have a high glycemic index, which is bad for endurance.
Thanks Carla for suggesting fruit…..I eat a lot of bananas, but assumed that other fruits have a high sugar content. Most fruits have a LOW glycemic index, so I know to go ahead and dig into those after all!
