Around 23% of the calories in yogurt (whole milk, plain) 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 81 dairy foods in the database, yogurt (whole milk, plain) ranks 60th by protein per serving, and 437th out of all 796 foods on the site. Set against cheddar cheese, another dairy food entry in the database, a serving carries about 0.5 g less protein (cheddar cheese has 6.4 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 above is counted by piece at 170 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
