PROTEIN CONTEXT
Is spinach a high-protein food?
Spinach does contain protein, but it is not a practical high-protein food by normal serving size.
A cup of raw spinach provides less than 1 g of protein because the leaves are mostly water and the serving is light.
It can contribute a little protein as part of a meal, but protein-rich foods are needed if protein is the main goal.
PUT IT IN CONTEXT
How much spinach would provide 20–30 g of protein?
These large amounts show why spinach is better treated as a vegetable that contributes some protein, not as a primary protein source.

Nutrition data and methodology
Nutrition and serving values use USDA FoodData Central SR Legacy record 168462 for raw spinach. It reports 2.86 g of protein and 23 kcal per 100 g, with one cup of raw spinach weighing 30 g.
Cooked spinach is more compact because it loses water, so a cup of cooked spinach contains much more spinach by weight and therefore more protein than a cup of raw leaves.

Cooking does not create protein, but it reduces volume and water. A cup of cooked spinach therefore contains much more spinach by weight than a cup of raw leaves and can provide more protein per cup.
