Does the sugar she can sense include the sugar recently eaten by a person?

It only applies to the sugar she makes via magic. 

So if someone like, ate her sword-lollipop, then I guess. If they ate a pastry from a bakery, then nah.

Why would you eat her sword though?

She needs it to hit witches with.
