Can spinach and mulberries be eaten together?
Generally speaking, spinach and mulberries are not recommended to be consumed together. The detailed analysis is as follows:

Spinach contains iron, while mulberries contain tannic acid. Tannic acid may combine with iron to form insoluble complexes, potentially affecting iron absorption in the human body. Additionally, both spinach and mulberries are considered cooling foods in nature. Consuming them together may intensify internal coldness and increase intestinal lubrication, possibly leading to discomforts such as diarrhea and abdominal pain.
Moreover, certain populations, such as individuals with kidney stones, those with poor gastrointestinal function, or those allergic to either food, may experience discomfort when consuming spinach and mulberries together. The oxalic acid in spinach may combine with components in mulberries, increasing the risk of kidney stones. People with weak gastrointestinal function may experience bloating, diarrhea, or other symptoms due to excessive intake of dietary fiber.
In daily diets, food should be reasonably combined according to individual constitution and needs. Overconsumption of any single food should be avoided to ensure comprehensive and balanced nutrition.
