New Delhi: Here is some good news for people who love to eat sweet potatoes. A new study suggests that sweet potatoes have good amount of Vitamin C as well as other essential vitamins, especially B6, which is responsible for maintenance of red blood cell metabolism.
Besides this, sweet potatoes are also believed to have other nutritional values and also contains a nutrient which may prove key to fighting breast cancer at early stages as per studies.
Wilmer Barrera and David Picha from Louisiana State University analysed a variety of sweet potato tissue types - mature leaves, young leaves, young petioles, buds, vine sections and root tissue.
They found that vitamin B6, vitamin C and vitamin B2 contents were higher in leaf tissue than in other tissue types.
"Our results indicate that mature and young leaves of sweet potato could provide significant amounts of vitamin B6 to the human diet," a news agency quoted the researchers as saying.
The vitamin B6 content in sweet potato leaves compares well with fruits and vegetables such as broccoli, avocados, carrots, bananas and cauliflower, they noted.
