Good to Know
Brands like King Oscar, Wild Planet, and Crown Prince pack their fish in actual olive oil rather than a cheaper soybean or vegetable blend, which is worth knowing if you care about the type of fat you're eating. Plain tins in oil or water stay at 0 net carbs per can, but the flavored varieties are where carbs sneak in, since options packed in tomato sauce, teriyaki glaze, or honey mustard can add a few grams of sugar. Eaten straight from the tin, mashed onto cucumber slices, or piled on a bed of greens, this is one of the easiest 22.6 grams of protein you can grab with no prep.
