About these values

The record is smooth peanut butter without added salt. The USDA record is "Peanut butter, smooth style, without salt" (SR Legacy, FDC ID 172470). It gives 22.21 g of protein and 598 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 2 tablespoons of peanut butter: 32 × 22.21 ÷ 100 = 7.1 g. Values on this page are rounded to 0.1 g.
