It is not recommended to eat cakes during a cough. The sugar content in cakes is high, and sugar has a phlegm-producing effect, which can aggravate a cough. Sugar tends to remain in the mouth and aggravate bacterial infections, which in turn can induce respiratory infections and aggravate coughing. In addition, the protein content in cakes is also relatively high. During coughing, the digestive function of the human gastrointestinal tract is weakened and the secretion of digestive enzymes is reduced, so the digestive ability of protein is reduced, and eating too much cake can cause indigestion. The cream content of cakes is also relatively high, mainly animal fats, and eating too much fatty substances can aggravate a cough, so it is not recommended to eat cakes during a cough. It is recommended to eat light, simple and easily digestible food, such as rice porridge, millet porridge and noodles, as well as eating fruits rich in vitamin C, which can strengthen the body’s resistance.
