The rich, greasy, and sweet foods, as well as the thick and flavorful delicacies, are often craved and enjoyed by people. However, excessive consumption can also lead to illness. This is because greasy foods can generate heat, and sweet foods can cause stagnation in the middle energizer. When the intake of greasy and sweet foods is excessive, it can obstruct the stomach and intestines, affecting the spleen and stomach's ability to regulate the flow of qi, leading to symptoms such as vomiting and diarrhea. It can also cause stagnation in the middle energizer, leading to the accumulation of dampness due to the impaired movement of middle yang. This dampness can then transform into phlegm and heat, resulting in dampness-heat and phlegm-heat disorders, or even consumptive thirst and wind generated by phlegm-heat. Furthermore, the internal accumulation can transform into dampness-heat, which can then reverse into the flesh and, when encountering pathogenic toxins, can ferment and lead to the formation of sores and abscesses. This is what the Suwen-Shengqi Tongtian Lun refers to when it says: "The transformation of rich and greasy foods can lead to the development of major illnesses."
