National Cinnamon Raisin Bread Day (September 16): cinnamon runs GL 0, raisins concentrate a grape's sugar into a small package, and the enriched dough carries the rest — a slice-by-slice GL lesson.

The Day and the Loaf

National Cinnamon Raisin Bread Day (September 16) celebrates a swirl bread where the three components have three very different GL stories: cinnamon is free, raisins are concentrated sugar, and the enriched dough is the base load. Reading the slice means reading all three.

Cinnamon Note

Cinnamon runs GL 0 per 100g and has a modest research file of its own — small trials suggest mild glucose benefits. The database's cinnamon page carries the spice's zero, which makes it the one ingredient in the loaf that costs nothing. Its flavor lets bakers cut added sugar without losing the signature taste.

Raisin Math

Raisins are grapes with the water removed — which concentrates the sugar into a small, dense package. The database's golden raisins carry a moderate GL per serving, and a swirl bread's raisin distribution is uneven, so two slices from the same loaf can differ. The measured slice: whole wheat base, cinnamon-forward, raisins as the accent rather than the filling. The database's whole wheat bread page shows the base that keeps the slice moderate.
