Every 100 kcal of brussels sprouts brings 7.1 g of protein. On that measure it ranks 33rd of the 105 vegetables in this database and 335th of all 796 foods on the site. Measured by weight instead, its 2.55 g per 100 g ranks 33rd in its group.
Around 28% of the calories in brussels sprouts 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.
Weight for weight, brussels sprouts has 5.1 g of protein for each gram of fat (2.55 g against 0.5 g per 100 g).
Set against artichoke, another vegetable entry in the database, a serving carries about 0.5 g more protein (artichoke has 3.5 g per 1 medium).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by volume at 156 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
