Sweet potato skin is definitely edible and highly nutritious. It contains fiber, vitamins (A, C, and E), minerals like potassium and manganese, antioxidants, and phytochemicals that offer various health benefits. Eating sweet potato with the skin on increases fiber intake, which supports digestive health and can help manage blood sugar and cholesterol. The skin is safe to eat both raw (if washed thoroughly) and cooked, but it should be scrubbed well before consumption to remove dirt and debris. Some people might want to limit consumption if they are at risk for kidney stones due to oxalates in the skin. Overall, sweet potato skin adds valuable nutrients and texture to meals and can be eaten in most sweet potato recipes.
