Disease description:

I am a 30-year-old woman. Recently, I found that the sweet potatoes stored at home have sprouted, and I'm not sure whether they are still safe to eat. I usually live frugally and don't want to waste food, but I'm concerned about potential health risks. Can sprouted sweet potatoes still be consumed?

After sprouting, sweet potatoes are still edible, but they must be carefully handled to ensure safety. Unlike potatoes, sweet potatoes naturally contain lower levels of solanine. Sprouting itself does not cause toxin production, but the sprouting process is usually accompanied by moisture loss and reduced nutritional value, which may result in a decline in texture and taste. Additionally, if mold develops or black or brown spots appear on the skin during storage, toxins may be present, making them unsuitable for consumption. The safety of sweet potatoes mainly depends on their storage conditions and physical appearance, rather than simply whether they have sprouted.

Before deciding to consume a sprouted sweet potato, examine its overall condition. If the surface is smooth, odorless, and shows no signs of mold, remove the sprouted portion completely, along with surrounding tissue, to reduce any potential risk. During preparation, it is recommended to cook the sweet potato thoroughly until fully done. To prevent sprouting, store sweet potatoes in a dry, cool, well-ventilated location away from direct sunlight or damp conditions. If a sweet potato has sprouted extensively or has become soft in texture, it is best to discard it to avoid potential health risks.
