About these values

The record is white bread made commercially. The USDA record is "Bread, white, commercially prepared (includes soft bread crumbs)" (SR Legacy, FDC ID 174924). It gives 8.85 g of protein and 266 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 slice of white bread: 29 × 8.85 ÷ 100 = 2.6 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
