Sometimes your stomach reacts badly after eating too much persimmon. Its tannins can irritate the digestive lining and make you feel uneasy or uncomfortable for a while.

Firm stools may cause discomfort during bowel movements
Children and the elderly are more prone to constipation

Health Tip: Drink at least 2 liters of water per day when eating fiber-rich fruits to keep digestion smooth.
