Generally, it only takes 30 minutes to adjust the oven to 220°C. If the temperature is 240°C, it only takes 25 minutes.

Taboos for eating roasted sweet potatoes

1. Sweet potatoes should not be eaten on an empty stomach. Due to the high sugar content of sweet potatoes, eating them on an empty stomach will cause people to produce a lot of gastric acid. Excessive gastric acid will irritate the gastric mucosa and cause acid reflux, making people feel heartburn. At the same time, sweet potatoes also contain an oxidase that produces a large amount of carbon dioxide gas in the gastrointestinal tract, which can easily cause symptoms such as gastric bloating and burping.

2. Patients with gastrointestinal diseases such as gastric ulcers and bloating should not eat sweet potatoes. The sugar in sweet potatoes tends to produce a large amount of gastric acid in the stomach, which increases the pressure in the stomach. For people with poor stomachs, this can irritate the ulcer surface or gastric mucosa, causing gastric discomfort.

3. Sweet potatoes cannot be eaten with anything too sweet. Because sweet potatoes themselves are sweet, eating them with sweets will increase the possibility of gastroesophageal reflux.

4. In terms of time of day, it is best to eat sweet potatoes at noon. Because after eating sweet potatoes, it takes 4-5 hours to be absorbed in the human body. If you eat sweet potatoes at night, the body will not be able to absorb all the sugar, which will cause bloating.
