Eating Ornamental Sweet Potatoes: Are They Safe and Nutritious?
Ornamental sweet potatoes, also known as sweet potato vines, are popular for their attractive foliage and can be seen in gardens and landscapes. However, did you know that they are also edible? In this article, we will discuss the safety and nutrition aspects of eating ornamental sweet potatoes.
What are Ornamental Sweet Potatoes?
Ornamental sweet potatoes (Ipomoea batatas) are a type of sweet potato plant that is grown primarily for its decorative foliage. The leaves can come in various colors such as green, purple, and variegated. Some people also grow them as trailing houseplants or in hanging baskets.
While the roots of the ornamental sweet potato plant are edible, they are not typically grown for consumption because they are smaller and not as sweet as traditional sweet potatoes. However, some people do eat them, whether out of curiosity or necessity, and there are a few things to consider before consuming them.
Are Ornamental Sweet Potatoes Safe to Eat?
The short answer is yes, ornamental sweet potatoes are safe to eat, but with some caveats. Firstly, it's important to note that not all types of ornamental sweet potatoes are edible. Some cultivars contain higher levels of toxic compounds such as oxalic acid, which can cause digestive issues and kidney damage if consumed in large quantities.
Secondly, even if you have an edible variety, it's crucial to wash and cook the roots thoroughly before eating them. Like other root vegetables, ornamental sweet potatoes can harbor bacteria and parasites that cause foodborne illnesses such as E.coli and salmonella. Boiling, roasting, or frying the roots until they are soft and fully cooked can help reduce the risk of contamination.
What are the Nutritional Benefits of Eating Ornamental Sweet Potatoes?
Despite being smaller and less sweet than traditional sweet potatoes, ornamental sweet potatoes still contain a range of nutrients that can benefit your health. They are a good source of fiber, vitamins A and C, potassium, and manganese.
Fiber helps regulate digestion and can lower the risk of heart disease and diabetes. Vitamins A and C are antioxidants that support immune function and skin health. Potassium is essential for proper nerve and muscle function, while manganese is involved in bone formation and metabolism.
How to Prepare Ornamental Sweet Potatoes for Eating
If you decide to try eating ornamental sweet potatoes, here are some tips on how to prepare them:
- Choose an edible variety such as 'Margarita' or 'Blackie'.
- Wash the roots thoroughly under running water and scrub off any dirt or debris.
- Peel the skin using a vegetable peeler or knife.
- Cut the roots into small pieces and boil, roast, or fry until they are soft and fully cooked.
- You can add salt, butter, or herbs for flavor.
While ornamental sweet potatoes are primarily grown for their decorative foliage, they are also safe to eat as long as you choose an edible variety and cook them properly. They may not be as sweet or large as traditional sweet potatoes, but they still offer several nutritional benefits such as fiber, vitamins, and minerals. So next time you spot an ornamental sweet potato vine, remember that it's not just a pretty plant but also a potential source of food!
