1. Lemon can't be eaten with seafood: seafood products such as shrimp, crab, sea cucumber and jellyfish are rich in nutrients such as protein and calcium, while the fruit acid content in lemon is relatively high. If lemon and seafood are eaten at the same time, the fruit acid in lemon will solidify protein and combine with calcium to produce indigestible substances, which will not only reduce the nutritional value of food, but also cause gastrointestinal discomfort;

Lemon is very similar to milk: milk is also rich in protein and calcium. Eating lemon and milk together will also affect the digestion of the stomach;

3. Lemon should not be eaten with carrots: carrots contain ascorbic acid enzymes, which will destroy vitamin C in lemons.
