Spinach is undoubtedly one of the most nutritious veggies on this list. 1 cup or 155g of frozen spinach has up to 550mg of potassium. It is also loaded with a variety of essential nutrients such as magnesium, folate, vitamin K, and vitamin A. Similarly, 3 cups or 100g of raw spinach have around 560mg of potassium. Keep in mind that 100 g of raw spinach can be visually more on your dish than the same amount of frozen spinach. [15]
