How to remove oxalic acid from spinach

If you don't pay attention to some methods and techniques in your diet, it is easy to get sick from your mouth. This does not just mean not paying attention to hygiene when eating, but that many foods contain some substances that are harmful to health. These substances must be removed before you can eat them with confidence. For example, the oxalic acid in spinach cannot be ignored. So how can you remove the oxalic acid in spinach?

Spinach contains a lot of oxalic acid, more than 0.1/100. When it meets calcium, it will form calcium oxalate, which will affect the absorption and utilization of calcium and iron. Calcium oxalate can also accumulate in the kidneys and bladder, which can easily lead to urinary stones. Therefore, patients with hyperuricemia and kidney stones should not eat too much. However, as for the oxalic acid in spinach, 80% of the oxalic acid can be removed by blanching it in boiling water. The oxalic acid in spinach has been destroyed, so not much is taken into the body and there is no need to worry too much. In addition, when eating spinach, you should drink more water and maintain a large urine volume to reduce the formation of calcium oxalate.

Spinach is sweet, cool, non-toxic, and enters the lung, intestine, and stomach meridians. It has the functions of nourishing blood, stopping bleeding, and moisturizing dryness. It is mainly used to treat nosebleeds, bloody stools, and difficulty urinating, etc. In addition, it can quench thirst, benefit the stomach and intestines, detoxify, and relieve alcohol. Spinach can moisten dryness, promote bowel movements and aid digestion. It is especially suitable for the elderly, infants and patients with hemorrhoids. Spinach can stimulate pancreatic secretion and is beneficial for diabetes.

Usually people eat spinach by throwing the washed spinach directly into the pot, or making soup. Experts believe that this way of eating is unscientific. Experts say that spinach has the highest oxalic acid content among all foods, and oxalic acid easily combines with calcium in the human body to form insoluble calcium oxalate. Calcium oxalate is not only unable to be absorbed and utilized by the human body, but also hinders the body's absorption of calcium. Therefore, the cooking method is crucial when eating spinach.

For pregnant women, in order to prevent the adverse effects of spinach on the human body, prevent the formation of stones, and affect the absorption of calcium, it is best to blanch the spinach in boiling water when cooking. After blanching, most of the oxalic acid can be released. At this time, pour out the water, take out the spinach, and either mix it with cold salad or stir-fry it, which can reduce the destructive effects of oxalic acid to a certain extent.

The above introduction on how to remove oxalic acid in spinach is very clear. In order to reduce unnecessary harm and trouble and protect one's own health, various dietary precautions cannot be ignored. In fact, there are still many ways to remove oxalic acid. In addition to blanching it in hot water, it can also be eaten correctly with other foods.
