What Are Purple Sweet Potatoes?
Purple sweet potatoes (Ipomoea batatas) are distinct from the more common orange and white varieties. They are characterized by their deep purple flesh, which is due to the presence of anthocyanins—powerful antioxidants that provide numerous health benefits. The skin of purple sweet potatoes can range from purple to brown, depending on the specific variety.
Is Purple Sweet Potato the Same as All Sweet Potatoes?
While purple sweet potatoes belong to the same species as orange and white sweet potatoes, they are different in several key ways:
- Nutritional Content: Purple sweet potatoes are higher in antioxidants, particularly anthocyanins, which have been linked to various health benefits, including reduced inflammation and improved heart health. A study published in the Journal of Medicinal Food highlighted the antioxidant capacity of purple sweet potatoes compared to other varieties (Shih et al., 2010).
- Flavor Profile: Purple sweet potatoes tend to have a slightly sweeter and nuttier flavor than their orange counterparts, making them a versatile ingredient in both savory and sweet dishes.
