About these values

The record is cheddar cheese. The serving is the reference amount the record lists. The USDA record is "Cheese, cheddar" (Foundation, FDC ID 328637). It gives 23.3 g of protein and 408 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 slice of cheddar: 17 × 23.3 ÷ 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.
