What should not be eaten with red grapes?

Under normal circumstances, red grapes should not be consumed together with foods such as milk, ginseng, hawthorn, tomatoes, or persimmons, or with medications including loratadine tablets, minocycline hydrochloride capsules, ibuprofen sustained-release tablets, warfarin sodium tablets, and gliclazide tablets. If discomfort occurs after eating red grapes, prompt medical attention is recommended to avoid delaying treatment. Specific details are as follows:

I. Foods

1. Milk: Certain components in red grapes may react with the proteins in milk, potentially causing diarrhea. Therefore, it is advisable to avoid drinking milk for a period of time after consuming red grapes.

2. Ginseng: The tannic acid in red grapes can bind with the proteins in ginseng, leading to precipitation that affects ginseng absorption and efficacy. Thus, individuals taking ginseng should avoid consuming red grapes.

3. Hawthorn: Hawthorn contains abundant organic acids, while red grapes are rich in vitamin C. Consuming them together may cause a reaction between the organic acids and vitamin C, resulting in gastrointestinal discomfort.

4. Tomatoes: Both tomatoes and red grapes are rich in vitamins, but when eaten together, they may lead to nutrient loss and reduced nutritional value.

5. Persimmons: Both red grapes and persimmons are considered cold-natured foods. Eating them together may increase the burden on the gastrointestinal tract, leading to symptoms such as abdominal pain and diarrhea.

II. Medications

1. Loratadine Tablets: Red grapes contain abundant organic acids, which may interact with the chemical components in loratadine, potentially reducing its effectiveness.

2. Minocycline Hydrochloride Capsules: The tannic acid in grapes may combine with this medication to form insoluble compounds in the urinary tract, possibly causing urinary obstruction or kidney damage.

3. Ibuprofen Sustained-Release Tablets: Red grapes are high in vitamin C, while ibuprofen sustained-release tablets may disrupt the structure of vitamin C, rendering it ineffective and potentially affecting the drug's efficacy.

4. Warfarin Sodium Tablets: Red grapes contain certain anticoagulant components. Taking them with this medication may increase the risk of bleeding.

5. Gliclazide Tablets: Red grapes have relatively high sugar content. Consuming them with blood glucose-lowering drugs may cause fluctuations in blood sugar levels, affecting both drug efficacy and patient health.

It should be noted that although red grapes are nutritious, excessive consumption may lead to digestive issues such as diarrhea and abdominal pain. Therefore, they should be eaten in moderation. Drinking water immediately after eating red grapes is not recommended, as it may easily trigger diarrhea. Additionally, individuals with diabetes, constipation, or those with spleen and stomach deficiency-cold should limit or avoid red grape consumption to prevent worsening of their conditions.
