What fruits should not be eaten with century eggs?

Preserved eggs refer to pine flower eggs (also known as century eggs). Pine flower eggs are generally not recommended to be consumed together with fruits such as persimmons, strawberries, kiwifruits, citrus fruits, and watermelons. If you are unsure whether a particular fruit can be eaten with pine flower eggs, it is advisable to consult a doctor. Specific details are as follows:

1. Persimmons: Persimmons contain large amounts of tannic acid, which can easily form precipitates when combined with the protein in pine flower eggs. This not only affects taste but may also impair the body's absorption of nutrients. Additionally, lead elements present in pine flower eggs might interact with certain components in persimmons, increasing potential health risks.

2. Strawberries: Strawberries contain relatively high levels of tannic acid. When consumed with pine flower eggs, they may also form precipitates that interfere with nutrient absorption. Moreover, the high vitamin C content in strawberries may react with the lead in pine flower eggs, producing substances harmful to the body.

3. Kiwifruit: Kiwifruit is rich in vitamin C, while pine flower eggs contain significant amounts of lead. Vitamin C may react with lead, potentially causing symptoms such as indigestion or abdominal pain. Therefore, it is recommended to avoid consuming pine flower eggs together with kiwifruit.

4. Citrus fruits: Citrus fruits such as oranges and grapefruits are also high in vitamin C. Consuming them with pine flower eggs may increase the risk of reactions between vitamin C and lead, leading to adverse health effects. Furthermore, the acidity of citrus fruits may irritate the gastric mucosa, and when combined with pine flower eggs, could exacerbate stomach discomfort.

5. Watermelon: Watermelon is considered a cold-natured fruit, while preserved eggs may contain certain irritants produced during processing. Eating them together may irritate the gastrointestinal mucosa, leading to symptoms such as abdominal pain and diarrhea. This combination is especially likely to cause discomfort in individuals with cold constitutions.

It should be noted that pine flower eggs themselves contain some lead and other potentially harmful substances; therefore, they should be consumed in moderation and not excessively.
