What is incompatible with Chinese dates (jujubes)?

　　Under normal circumstances, jujube (Chinese date) is incompatible with persimmon, milk, cucumber, animal liver, crab, etc. Detailed explanations are as follows:

　　1. Persimmon

　　Both red dates and persimmons contain high levels of tannins. Consuming them together may lead to the formation of indigestible masses in the stomach, causing gastrointestinal discomfort. Tannins can combine with proteins in gastric juice to form hard clumps that may require surgical removal.

　　2. Milk

　　Red dates contain high amounts of pectin and fiber, while milk is rich in protein. When consumed together, the pectin and fiber in red dates may bind with the protein in milk to form coagulated masses that are difficult to digest, affecting digestion and nutrient absorption.

　　3. Cucumber

　　Cucumbers contain enzymes, especially vitamin C-degrading enzymes, while red dates are rich in vitamin C. Consuming red dates with cucumbers may result in the degradation of vitamin C by these enzymes, thereby reducing its nutritional value.

　　4. Animal Liver

　　Animal livers are rich in metal ions such as copper and iron, which can cause oxidation and inactivation of vitamin C in red dates. Additionally, consuming animal liver and red dates together may interfere with the absorption and utilization of nutrients from both foods.

　　5. Crab

　　Crab is rich in protein, which may react with vitamin C in red dates to form indigestible substances, potentially leading to digestive problems such as indigestion or diarrhea. Crab is also cold in nature, conflicting with the warm nature of red dates, which may trigger conditions related to heat and cold imbalances.

　　Although the above-mentioned foods are considered incompatible with red dates, they are not absolutely prohibited from being consumed together in daily diets. With proper pairing and moderate consumption, significant health impacts are unlikely.
