How to eat spinach is the healthiest?

Because spinach contains a lot of oxalic acid, oxalic acid will affect the absorption of calcium. When the human body ingests a large amount of oxalic acid at one time, oxalic acid will combine with calcium in food to form a precipitate, which will affect the absorption of calcium. Don't worry, oxalic acid in food will hardly cause poisoning, so don't worry too much. So in fact, spinach was hacked for a reason.

But friends who like spinach don't have to panic, because oxalic acid is unstable to heat and soluble in water, so spinach is very healthy after cooking. The recommended daily intake of vegetables is 300-500 grams, of which dark vegetables account for half of the total vegetables. Spinach is honored to belong to the category of dark vegetables, which means that it is good to eat two handfuls of spinach every day.
