About these values
The record is whole-wheat bread made commercially. The USDA record is "Bread, whole-wheat, commercially prepared" (SR Legacy, FDC ID 172688). It gives 12.45 g of protein and 252 kcal per 100 g.
Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 slice of whole-wheat bread: 32 × 12.45 ÷ 100 = 4.0 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.
