Every 100 kcal of bacon brings 6.5 g of protein. On that measure it ranks 115th of the 133 meats in this database and 379th of all 796 foods on the site. Measured by weight instead, its 35.7 g per 100 g ranks 1st in its group.
Around 26% of the calories in bacon come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
By weight, fat outweighs protein in bacon: 43.3 g of fat per 100 g against 35.7 g of protein, a ratio of 0.8 to 1.
Set against deli roast beef, another meat entry in the database, a serving carries about 0.5 g more protein (deli roast beef has 5.2 g per 1 oz).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is counted by piece at 16 g, and it covers about 11% of the 50 g FDA Daily Value for protein.
