A typical 1 cup shredded serving of radicchio contains 0.6 grams of protein (1.43 g per 100 g), which makes it only a minor source of protein. That covers roughly 1% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 25% of the calories in radicchio 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.
Among the 105 vegetables in the database, radicchio ranks 91st by protein per serving, and 765th out of all 796 foods on the site. Set against jalapeno peppers, another vegetable entry in the database, a serving carries about 0.5 g more protein (jalapeno peppers has 0.1 g per 1 pepper).
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 above is measured by volume at 40 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
