Are granola bars a healthy breakfast?

They can be a reasonable snack, but many are closer to a candy bar than a bowl of oats — check the sugar and ingredient list, since corn syrup or honey is often the second or third ingredient.

Why is oatmeal so much lower in sugar than a granola bar made from the same oats?

The oats themselves have almost no sugar. A granola bar needs a sticky binder to hold its shape, and that binder — honey, syrup, or brown sugar — is where the sugar comes from.

How Much Sugar Is in a Granola Bar?

A standard granola bar has about 8 g of added sugar — small on paper, but many bars are candy bars wearing an oats-and-honey label.

Fine in a portion — worth keeping an eye on.

A single granola bar carries about 8 g of added sugar, which sounds modest — until you look at what's holding the oats together. Most granola bars use corn syrup, honey, or brown sugar as the binder, and chocolate-coated or 'chewy' varieties push well past this figure, some approaching a candy bar's worth of sugar in a wrapper that says 'oats' and 'whole grain'.

This is the same health-halo problem as granola itself: the oats are genuinely wholesome, but the sweetener binding them does most of the work. Compare it to a bowl of plain oatmeal, which has almost no sugar for a similar amount of oats — the granola bar's convenience comes at a real sugar cost.
