About these values

The record is light tuna canned in water and weighed after draining, so the can portion is the drained fish. The USDA record is "Fish, tuna, light, canned in water, drained solids" (Foundation, FDC ID 334194). It gives 19 g of protein and 90 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 can of tuna, drained: 107 × 19 ÷ 100 = 20.3 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.
