Which has higher calorie content, century eggs or boiled eggs?

In general, under equal weight, the calorie content of century eggs (preserved eggs) is slightly higher than that of boiled eggs, although the difference in calories between the two is not significant. Selection should be based on individual nutritional needs and portion size. The detailed analysis is as follows:

Although no additional oil or fat is used during the production of century eggs, the pickling process using lime and soda ash causes significant water loss, leading to a concentration of nutrients and thus slightly higher caloric density. Both foods are rich in high-quality protein. Boiled eggs retain the egg's original nutrients, whereas century eggs contain much higher sodium levels. Excessive consumption may lead to excessive sodium intake.

In daily diet, if low-calorie and natural nutrition are priorities, boiled eggs are preferable. For those who enjoy unique flavors, moderate consumption of century eggs is acceptable, though individuals with hypertension should especially limit their intake. Overconsumption of either type should be avoided to prevent increased gastrointestinal burden and discomfort such as bloating.

Choose according to your personal health condition and taste preference. By reasonably controlling portion sizes, you can enjoy the nutritional benefits of these foods while avoiding adverse effects from excessive calorie or sodium intake.
