Considering that when children have a fever, the secretion of digestive enzymes decreases, the secretion of digestive juices decreases, symptoms of indigestion will occur, and it is also more likely to have allergic symptoms, so there are certain precautions to be taken when eating fruit when you have a fever. Generally do not eat crude fiber-rich fruits, such as pears, jujubes, kiwi, because after the intake of crude fiber-rich fruits, the intestinal water will increase, stools will be softened, and bloating and other digestive symptoms may occur. Do not eat tropical fruits during fever, such as mango, durian, etc., because this kind of tropical fruits may lead to allergies and aggravate the symptoms of the original disease. Don’t eat nuts when you have a fever because nuts are also very allergenic.
