Can crabs and spinach be eaten together?
Generally speaking, crabs and spinach can be consumed together, but in moderation. The detailed explanation is as follows:

Crabs are rich in protein, phosphorus, iron, vitamins, and other nutrients, while spinach contains abundant beta-carotene, calcium, iron, coenzyme Q10, vitamins, oxalic acid, and various other nutrients. Consuming crabs and spinach together in moderation can provide multiple nutrients such as vitamin A, folic acid, and potassium, which helps achieve balanced nutrition, enhance physical health, and promote beauty and skin care.
However, individuals with weak gastrointestinal function, those suffering from gout or hyperuricemia, and people allergic to seafood are advised to minimize or avoid consuming crabs and spinach together. Crabs are cold in nature and may cause indigestion; when combined with oxalic acid in spinach, they may form indigestible substances that burden the gastrointestinal tract. Moreover, both crabs and spinach are high in purines, making them unsuitable for large consumption by individuals with gout or hyperuricemia.
When consuming crabs and spinach together, attention should be paid to moderation and ensuring the freshness and cleanliness of the ingredients. Maintaining a balanced diet and appropriately combining various ingredients in daily meals helps preserve overall health.
