You can eat sweet potatoes raw, but not regular potatoes. But what about the unhealthy oxalic acid in sweet potatoes? Here’s how healthy raw sweet potatoes really are.
Eat sweet potatoes raw: That’s why they’re the better potatoes
It sounds paradoxical: while you should never eat potatoes raw, that’s no problem with sweet potatoes. But the reason is obvious: sweet potatoes are not potatoes at all. Instead, sweet potatoes belong to the morning glory family and not to the nightshade family like the potato. So sweet potatoes are much more of a root. Compared to potatoes, sweet potatoes also contain no solanine. This is the toxic substance, which is why you should not eat potatoes raw.
Sweet potatoes contain many healthy ingredients. While some are broken down during cooking and baking, when consumed raw you can benefit from:
Carotenoids and anthocyanins (antioxidants)
Potassium (helps against stress, among other things)
Minerals such as calcium, zinc and iron
Vitamin A (good for the eyes)
Vitamin C (strengthens the immune system)
Vitamin E (protects against free radicals)
lots of carbohydrates with a high fiber content, which keeps you full for longer.
Basically, you can eat sweet potatoes raw and benefit from the many good ingredients. However, it contains oxalic acid, which can be harmful to humans.
Oxalic Acid in Sweet Potatoes – What Does It Mean?
Sweet potatoes contain quite a lot of oxalic acid. This damages the kidneys, but can be broken down by boiling or long soaking. At the same time, oxalic acid inhibits the absorption of magnesium, calcium and iron. For this reason, you should be careful not to consume excessive amounts of foods high in oxalic acid. So you can eat sweet potatoes raw, but in moderation and not by the kilo.
The combination is also important: For example, calcium promotes oxalic acid absorption. So when you combine calcium-rich foods like broccoli with sweet potatoes, the oxalic acid will be balanced. You can also combine kale, soy strips or sesame seeds.
According to the Bavarian consumer advice center, it is not a problem to eat sweet potatoes raw from time to time: “Unlike table potatoes, sweet potatoes can also be served raw as finger food or in a salad,” says nutrition expert Silke Noll from the consumer advice center.
