Can green beans and spinach be eaten together?
Under normal circumstances, green beans and spinach can be eaten together. Details are as follows:

Both green beans and spinach are rich in nutrients, such as vitamins, minerals, and dietary fiber. They do not produce harmful substances during cooking and therefore can be cooked and consumed together. Consuming them together can increase dietary diversity and nutrient intake, which helps maintain good health.
Spinach contains relatively high levels of oxalic acid, excessive intake of which may affect calcium absorption and potentially increase the risk of kidney stones. Individuals with a history of kidney stones or those sensitive to oxalic acid should avoid consuming large amounts of both green beans and spinach together. For individuals with certain medical conditions, such as kidney insufficiency or hyperuricemia, consumption of foods containing oxalic acid should be limited. Some people may be allergic to spinach or green beans, and in such cases, they should not be consumed together.
In daily diets, balanced intake of various foods and maintaining a reasonable dietary structure are key to maintaining health.
