2. Spinach

If you are fan of the famous cartoon character Popeye, you will know that his source of strength came from spinach. This food is full of potassium, Vitamin A, Vitamin K, iron, manganese and folate. Consuming a cup of raw spinach can cover more than half of the DV for essential Vitamin A that is helpful in improving your vision, reproduction and immune system. Cooked spinach offers 100% of your DV and you can try adding these to your salad or opt for a sauté with garlic and olive oil.
