Every 100 kcal of butternuts brings 4.1 g of protein. On that measure it ranks 1st of the 31 nuts in this database and 517th of all 796 foods on the site. Measured by weight instead, its 24.9 g per 100 g ranks 1st in its group.
Around 16% of the calories in butternuts come from protein, so it is more of an energy food than a protein food. 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 butternuts: 57 g of fat per 100 g against 24.9 g of protein, a ratio of 0.4 to 1.
Set against almonds, another nut entry in the database, a serving carries about 1.1 g more protein (almonds has 5.9 g per 1 oz).
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 weight at 28 g, and it covers about 14% of the 50 g FDA Daily Value for protein.
