Sweet potato leaves, the leaves of the sweet potato plant, are classified as a wild vegetable in China's food composition tables, but they can be grown in one's own garden. In terms of nutrients, sweet potato leaves are similar to other green leafy vegetables, containing a certain amount of protein, carbohydrates, dietary fiber, a small amount of fat, and various nutrients such as vitamins and minerals. Additionally, they contain bioactive plant compounds such as flavonoids and chlorogenic acid.

According to data from China's food composition tables, every 100 grams of sweet potato leaves contains 4.8 grams of protein, 5968 micrograms of beta-carotene, 56 milligrams of vitamin C, 174 milligrams of calcium, 495 milligrams of potassium, and 3.4 milligrams of iron. The protein, vitamin, and mineral (such as calcium, iron, and potassium) content of sweet potato leaves is at a relatively high level compared to other green leafy vegetables (such as spinach, chives, and water spinach).
The beta-carotene content in sweet potato leaves is even higher than that of carrots. Beta-carotene can be converted into vitamin A in the body, which plays a major role in enhancing visual function (such as improving the eye's adaptation from light to dark), maintaining the integrity of skin and mucous membranes, promoting immune function, promoting growth and development, and strengthening reproductive function.
As for some of the bioactive components in sweet potato leaves, such as flavonoids, they have good effects in inhibiting tumor cell activity, as well as antibacterial, antiviral, and anti-inflammatory effects, which can reduce the risk of developing certain chronic diseases. Another example is chlorogenic acid, which has biological activities such as antioxidant, free radical scavenging, anti-inflammatory, antibacterial, and antiviral effects.
Although sweet potato leaves are rich in many active components, their effects are only realized when a certain amount is consumed. In other words, if you don't eat it regularly, don't expect it to have any therapeutic effects. Therefore, it's best to treat it as a normal vegetable. What's more important in your daily diet is to maintain food variety and ensure nutritional balance.
