You cannot eat pork liver during a cold, although it is rich in nutrients. However, during the cold period, the digestive function of the gastrointestinal tract will be weakened by the influence of cold virus or bacteria, and the secretion of digestive juices will be reduced, so indigestion will easily occur. Pork liver is a difficult food to digest, and it is especially likely to increase the burden on the gastrointestinal tract, causing some gastrointestinal discomfort and even nausea, vomiting or abdominal pain and diarrhea. Pork liver is a non-vegetarian food and has the effect of producing phlegm. If you eat meat food, it has the effect of producing phlegm and will aggravate the cough and phlegm, so you should not eat pork liver during cold. You should eat a simple, light and easily digestible diet, or eat fresh fruits and vegetables to get enough vitamin C. This will help the body to strengthen its resistance and thus promote recovery from the cold, and you should drink and rest more.
