How Spinach Fits Into a Diet
Spinach is useful when you want a very low-calorie leafy green with vitamin K, folate, carotenoids, potassium, and meal volume.
Pair spinach with eggs, beans, potatoes, lentils, fish, chicken, tofu, olive oil, citrus, or whole grains to improve satiety and meal balance.
Raw leaves, boiled spinach, sauteed spinach, frozen spinach, creamed spinach, and restaurant sides differ because water loss, oil, cream, and salt change the final serving.
