Children who occasionally eat spicy food in small amounts are generally not harmful, but long-term consumption of excessively spicy food may cause mouth ulcers, gastric mucosal irritation, skin acne and so on. 1. Mouth ulcers: children often eat too spicy food, may produce stimulation of the oral mucosa, which in turn increases the incidence of mouth ulcers, causing adverse symptoms. 2. Stimulation of the gastric mucosa: Eating spicy food, after entering the stomach, may cause stimulation of the gastric mucosa, thus causing the stomach to secrete a large amount of gastric acid, stomach pain and other related symptoms. 3. Skin acne: children often eat spicy food, is likely to cause the sebaceous glands to increase the secretion of oil, clogging the facial pores, thus causing skin acne. Children try to avoid eating spicy, to light diet, to ensure balanced nutrition, do not pick food partiality, eat some vegetables and fruits, more water, and so on.
