Spinach, frozen, boiled in unsalted water

Spinach is a leafy green vegetable. The figures here describe frozen spinach boiled in unsalted water. It provides vitamins and minerals, along with some protein. Per 100g, it contains 3.1g of protein, 1101µg of vitamin A (retinol equivalent), 840µg of vitamin K1 and 0.04g of salt.

Vitamin A supports normal vision and immune function, while vitamin K is needed for normal blood clotting. Vitamin K intake is also relevant to people taking warfarin, because changes in intake can affect how the medicine works. The salt content shown reflects preparation without added salt; adding salt during cooking would increase this. Full nutrient figures are in the tables below.
