MYTH: Natural sugar like honey is better for you than processed sugar.

A granola bar made with honey instead of high-fructose corn syrup is not better for you.

That's because sugar in natural products like fruit and synthetic products like candy is the same: "Scientists would be surprised to hear about the 'clear superiority' of honey, since there is a near unanimous consensus that the biological effect of high-fructose corn syrup are essentially the same as those of honey," professor Alan Levinovitz told Business Insider.

The problem is that candy and other related products typically contain more sugar per serving, which means more calories — a difference you should actually be watching out for.
