About these values

The record is top sirloin steak, lean only with the fat trimmed, cooked under a grill. Other cuts and fattier steaks differ. The USDA record is "Beef, top sirloin, steak, separable lean only, trimmed to 0" fat, choice, cooked, broiled" (SR Legacy, FDC ID 168635). It gives 30.29 g of protein and 188 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 3 oz of steak: 85 × 30.29 ÷ 100 = 25.7 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.
