Can eating cured pork cause “internal heat”?

In southern Chinese cities, many people traditionally preserve meat by curing it into “larou” (cured or smoked pork), which not only boasts rich, savory flavor but also boasts an exceptionally long shelf life. But does eating larou cause “internal heat” (a traditional Chinese medicine concept referring to symptoms such as sore throat, acne, or constipation)?

Does Eating Larou Cause Internal Heat?

Excessive consumption of larou may indeed lead to internal heat. While larou is delicious and flavorful, moderate intake generally poses no risk of internal heat. However, overconsumption increases the likelihood of such symptoms. This is because larou is typically produced via smoking or air-drying, resulting in very low moisture content. When consumed, the body must draw additional water from its own reserves to digest it—potentially causing dehydration and subsequent internal heat. In moderation, larou can effectively boost immunity and supply the body with essential nutrients, including protein, fat, and various carbohydrates.

Larou can be prepared in numerous ways. First, rinse the larou thoroughly and steam it for 20 minutes. Then slice the steamed larou thinly and cut garlic chives into segments. Heat a wok, add a small amount of oil and a few Sichuan peppercorns; once fragrant, remove the peppercorns. Add the larou slices and stir-fry until the fatty portions become translucent. Add a small amount of light soy sauce, mix well, then add the garlic chive segments and stir-fry until just cooked through before serving.

Larou is primarily made by curing meat and then air-drying it. It is nutritionally rich. We hope this answer has been helpful!
