If eaten at the same time, especially on an empty stomach, precipitation and condensation are likely to occur, forming hard lumps, causing gastrointestinal bloating, pain and other discomfort symptoms.

Sweet potatoes and persimmons should not be eaten at the same time in a short period of time. If you eat a lot, you should eat them at least five hours apart.
