Can spinach and mutton soup be eaten together?
Generally speaking, spinach and lamb soup can be eaten together, but it is not recommended to consume them in large quantities. The detailed explanation is as follows:

Lamb is rich in high-quality protein, iron, zinc, and B vitamins, and has functions of warming the middle jiao (upper digestive tract), strengthening the spleen, invigorating qi, and nourishing blood. Spinach contains abundant vitamin A, vitamin C, dietary fiber, and minerals such as iron and calcium, which can promote intestinal motility and supplement vitamins. When lamb soup and spinach are consumed together, the intake of proteins, vitamins, and minerals becomes more balanced. Additionally, the crispness of spinach can neutralize the greasiness of lamb soup, making the soup taste more delicious.
However, attention should be paid during consumption. Spinach contains oxalic acid. If cooked directly with lamb soup, oxalic acid may affect the absorption of minerals from the lamb. Therefore, it is recommended to blanch the spinach for 1–2 minutes first to remove most of the oxalic acid before adding it to the lamb soup. Moreover, lamb soup is warming in nature and excessive consumption may easily cause internal heat (fire) in the body. Spinach is slightly cooling in nature; consuming large amounts together may cause discomfort in individuals with weak gastrointestinal function. Therefore, intake should be controlled, especially for individuals with yin deficiency and excessive internal heat or sensitive digestive systems, who should consume it in moderation to avoid increasing the body's burden.
