Dr Michelle's carrot, ginger and sweet potato soupAlong with carrots, sweet potatoes are also an excellent source of antioxidants and Vitamin A. Apart from being extremely tasty, this superfood is also packed full of fibre, potassium, folate, Vitamin C, iron, copper and, perhaps most importantly, (as previously mentioned), beta-carotene. Additionally, not only do sweet potatoes pack in a good amount of iron, they also contain copper, a mineral that helps your body absorb iron.
