High in Vitamin C
Vitamin C is typically an essential water-soluble antioxidant that plays a significant role in many body functions. Especially, it is needed for the production of collagen, an important structural protein. Compared to other veggies, kale is high in vitamin C. On average, a cup of kale might contain more vitamin C than the whole orange. Thus, it is often recommended by healthcare providers in daily diet to prevent some health issues that are associated with lacks of vitamin C. [3]
