15 minutes.

Sweet potatoes of different sizes are cooked in a pot with the same heat, and the cooking time is different. Generally, palm-sized sweet potatoes can be cooked in an ordinary iron pot over high heat for 15 minutes. For example, cut the sweet potatoes into uniformly sized 1 cm pieces, boil them over high heat until the water boils, then turn to medium-low heat and simmer for about 10 minutes before they are cooked. If you want to cook sweet potatoes faster, you can cook them in a microwave or pressure cooker.

Side effects of sweet potatoes

Sweet potatoes are rich in sugar, which will increase blood sugar in diabetic patients and are not suitable for the control of diabetes. Excessive sugar content can also cause normal people to produce a large amount of gastric acid. Excessive gastric acid stimulates the stomach and causes gastric contraction, which can lead to adverse reactions such as acid reflux and acid vomiting, which is harmful to human health.

It is especially harmful to people with gastric ulcers, so people with peptic ulcers are not recommended to eat sweet potatoes. In addition, if diarrhea occurs when eating sweet potatoes, it may be that the digestive tract cannot tolerate sweet potatoes, so do not eat sweet potatoes to avoid adverse reactions such as diarrhea.
