Spinach is a nutritious vegetable and a good friend of human health. Spinach has a high iron content, and many people think it is a good product for iron supplementation. In fact, spinach can not only supplement iron, but also bring bad consequences. Because spinach not only contains a lot of vitamin C, but also contains a lot of oxalic acid (360 mg of oxalic acid per 100 g of spinach). When you eat a lot of spinach, calcium ions in the human body combine with oxalic acid in spinach to form water-insoluble calcium oxalate, thus reducing the necessary calcium ions in the human body. So eating spinach for a long time is harmful to people.
Is eating more spinach good for your health? Spinach is a vegetable that people often eat and has high nutritional value. Many people think that eating more spinach is good for your health, and the more you eat, the better. Actually, it's not. Eating more spinach has fewer advantages and more disadvantages. Spinach is rich in oxalic acid, which will react with calcium in food to produce calcium oxalate, but calcium oxalate can not be absorbed and utilized by human body, but will lose calcium in food. Therefore, eating spinach often will cause calcium deficiency in human body and affect human health. In addition, it is best to cook spinach in soup, and only eat vegetables without drinking soup, because oxalic acid is mostly dissolved in soup, which can reduce the loss of calcium.
