2. Salad Greens
Now, these are the most stereotypical healthy foods, and many people think of them as they taste too “green”, too empty, however, if you’re creative enough, they are enjoyable for everyone. Spinach, lettuce, kale, rocket and the others are excellent sources of Vitamin A, B9 (Folate), and K and contain a nice amount of iron, as well. Their energy content is almost nothing, 15 kilocalories per 100 g.
