Inverted sugar syrup for supplemental feeding?

I did a little more googling, and a little more reading and I had no idea how heated this debate is… holy cow. Seems like the consensus is that bees invert their own sugar with an enzyme invertase. So it is unnecessary to do it for them, and inverted sugar syrup can contain toxic compounds that develop in the conversion process. So from what I gather simple cane sugar syrup with minimal heating is best. Seems like if that is the case then any candies or fondant products would be equally as bad for them as they are extensively heated…
