1, no matter how you eat (boiling, frying, frying, soup), remember to blanch with boiling water before eating, and the time should not be too long. 1-2 minutes is enough. Too long will lead to the loss of vitamin C, so soak it in hot water for two or three minutes and take it out for later use. Doing so can remove most of the oxalic acid contained in spinach. After this part of oxalic acid is dissolved in water, spinach will not have astringency and other vitamins will not be destroyed.

2. In order to prevent the nutrients of spinach from being destroyed, cover the pot when cooking, try to avoid too much contact with air and heating for too long, and keep the vitamin C in spinach from being destroyed by oxidation to the maximum extent. At the same time, should it be served in bronze utensils and cooked with copper pots and shovels? Because bronzes, pots and shovels will accelerate the oxidation process of vitamins in spinach.

3, spinach should not be eaten with tofu, about 100 grams of spinach contains about 300 mg of oxalic acid. Tofu contains high content of protein, magnesium chloride and calcium sulfate. If it enters the human body at the same time as spinach, it will produce insoluble calcium oxalate, which will not only cause calcium loss, but also deposit into stones. So spinach and tofu had better not be eaten together.

4, spinach is good, but it should be moderate, not too much at a time, especially for patients with stones, because oxalic acid in spinach will aggravate the pathological changes of stones, especially for patients with urethral stones, they should be careful to eat, or not to eat, adults eat too much spinach, and will also cause hand and foot spasm due to calcium deficiency; Eating too much spinach can also cause the body to absorb less zinc. Zinc is an essential trace element for human body. Although the required amount is small, it has a great effect, especially for children, pregnant women and tuberculosis patients.

Don't throw away the bare roots of spinach in vain. Rich in vitamin K, it is unique to spinach in leafy vegetables. People usually know that vitamin K is called "the hero of stopping bleeding", also called coagulation vitamin. Because it can promote blood coagulation, it is an indispensable good friend of human beings. If we humans are short of vitamin K, once an accidental wound occurs and necessary surgical treatment is carried out, the coagulation time will be prolonged, and the wound and incision will bleed without healing. Although the average adult will not be short of vitamin K, they should continue to supplement it.
