Can spinach and dried shrimp be eaten together?
Generally speaking, spinach and shrimp skins can be consumed together, but it is not recommended to eat them in large quantities. The detailed explanation is as follows:

Spinach is rich in vitamin A, vitamin C, dietary fiber, and minerals such as iron and calcium. Vitamin A helps protect vision, while iron assists in preventing iron-deficiency anemia. Shrimp skins are rich in calcium and also contain high-quality protein, potassium, magnesium, and other trace elements. Combining the two can enhance nutritional benefits by complementing calcium and iron intake and promoting iron absorption through vitamin C. Additionally, the combination of dietary fiber and protein can increase satiety and promote intestinal motility, supporting digestive health.
However, spinach contains oxalic acid, which may combine with calcium to form calcium oxalate when consumed together with shrimp skins, thereby affecting calcium absorption. Therefore, it is recommended to blanch the spinach in boiling water for 1–2 minutes first to remove most of the oxalic acid before cooking it with shrimp skins. Moreover, shrimp skins are high in salt, so the amount of salt used during cooking should be reduced. Individuals with hypertension or weak kidney function should also control their consumption, ensuring the ingredients are fresh and thoroughly cooked.
