Is glucose syrup, High-fructose corn syrup and corn syrup the same thing?

Yes and No. Yes, in the sense that they are all forms of sugar.

No in the sense that they are chemically different. Glucose is one form of sugar, both HFCS, and corn syrup are primarily fructose, and they are made a little differently.

In the end your body converts them all to glucose via digestion to fuel your cells.

Most people eat too much sugar in general. It would be good for most to eat less of it. But focusing on avoiding just one form (i.e. High fructose corn syrup), is pointless, if you just replace it with another form of sugar.

Not exactly. High fructose corn syrup and corn syrup are rather similar, I do think there's a difference. They all can be thought if as sugars, however.

No, my friend.

Glucose syrup contains glucose, a simple sugar (monosaccharide), and HFCS (High Fructose Corn Syrup) contains fructose, which is another type of simple sugar (another monosaccharide), which is also called 'fruit sugar' as it's available in all fruits.

Edit:

I'm assuming some idiot, who hands out thumbs down, is incapable of understanding what I've written. Maybe they should get a bit of education before giving thumbs down.

All corn syrup contains fructose. HFCS has only a tiny bit more than regular corn syrup.

yep!! the exact same thing!
