Introduction: Human tastes are regional; for instance, people from Fujian have a sweet tooth, while those from Hunan love spicy food. This is actually an adaptation to the local natural environment. However, from a Traditional Chinese Medicine (TCM) perspective, human tastes are also connected to the five internal organs, and changes in taste reflect the needs of these organs.
Human tastes are like individual business cards. Some people naturally love sweets, some can't live without spicy food, and others are obsessed with sour tastes... In fact, besides factors like geographical environment, dietary habits formed from childhood, and genetic makeup, a preference for a certain taste can sometimes be a sign of nutritional imbalance or health issues. A sudden change in taste, on the other hand, could be a health warning that should be paid attention to.
Traditional Chinese Medicine posits that the five flavors (sour, bitter, sweet, pungent, and salty) originate from the qi of heaven and earth. The five organs each have a corresponding primary flavor, and each flavor has its corresponding organ. That is, sour enters the liver, bitter enters the heart, sweet enters the spleen, pungent enters the lungs, and salty enters the kidneys. A long-term preference for one or more flavors can trigger a "chain reaction" in the five organs, which is detrimental to health. Conversely, problems with the five organs can affect the taste function of the tongue, causing a person's likes and dislikes for the five flavors to change, leading to different dietary preferences or sudden changes in taste.
1. A preference for sour taste suggests liver issues. Sour flavor corresponds to the liver and has a nourishing effect on it. For example, dishes in Shanxi and Shaanxi are often very sour, which is due to the dry local climate where bodily fluids are easily depleted; thus, consuming sour food appropriately can nourish these fluids. A preference for sour taste or a sudden craving for it may be a reflection of liver problems. Long-term preference for sour foods or excessive consumption can lead to the liver failing to ensure the smooth flow of qi. Furthermore, because the sour flavor is astringent and constricting, overindulgence can hinder the normal physiological function of the stomach, causing problems with the spleen and stomach.
