                                According to research from PAK'nSAVE, a cup of frozen spinach can contain more than four times the nutrients, like fiber, folate, iron, and calcium, compared to a cup of fresh spinach. Deciding which spinach is better depends on your intended use, whether you are planning a fresh salad, a cooked dish, or a smoothie.
