Scrambled eggs? I dealt with some hypoglycemia as a teen/young adult. Protein was the best fix for me, though I still ate carbs. Everything in moderation, KWIM? But several small meals a day, and NO meal without a protein seemed to help me manage best. If I was feeling low, protein alone helped--cheese, eggs, nuts...those kinds of things.
I drink Nutrisweet constantly, with no problems. I think most of those nutrition scares are fairly dependent on your body and your dietary makeup.
But certainly, I'd venture to say that pop with Nutrisweet is better for her than the straight sugar in regular pop!
