Thanks everyone! So helpful....
So does anyone know how many teaspoons is 130g of glucose?

Oh, and during our lecture my know nothing teacher talked about "dangerous fad diets like Atkins" and how if you don't eat enough carbs you will go into ketoacidosis which is very life-threatnening. I had to try really hard to keep quiet on that one! The problem is that our main text says the exact same thing so disputing it would have been very difficult.
