Lentils are a great source of protein, fibre and iron. When looking for options to feed babies, it's especially important to keep in mind that babies need to consume sufficient iron after 6 months of age since their iron stores start to become depleted at this time. There are different forms of iron -- both animal and plant-based. Because lentils are plant-based, the iron is not quite as readily absorbed, but by pairing them with the sweet potato, which is a source of vitamin C, it helps to enhance the absorption of this mineral. That's why these two foods together are a winning combination!
