How much fiber is in white bread?
White Bread has 0.7 g of fiber per 1 slice (26 g). That is 3% of the daily value and a low amount for a grain.
Soluble vs insoluble
The split is approximate and comes from USDA SR Legacy analyses where available. Soluble fiber dissolves into a gel and is the type most linked to cholesterol and blood sugar effects. Insoluble fiber adds bulk and keeps things moving.
