It is recommended to blanch spinach before eating.
Because spinach is rich in oxalic acid, it is the highest amount of oxalic acid in green leafy vegetables. 200 grams of spinach contains about 1500 mg of oxalic acid. Oxalic acid will combine with free calcium ions in the body to form calcium oxalate crystals, which not only affects the taste of astringency, but also easily produces urinary stones and affects the absorption of calcium.
Oxalic acid is easily soluble in water, so it is generally recommended to blanch spinach to remove it.
What happens if spinach is not blanched.
Increased risk of stones.
Oxalic acid is generally absorbed in the small intestine of the human body, in the small intestine fluid, most of the oxalic acid and free calcium ions combine to form calcium oxalate crystals, the oxalic acid absorbed into the blood can form calcium oxalate with calcium ions in the blood, its solubility is very low, after the urine is concentrated in the kidneys, if it exceeds the solubility of calcium oxalate, it may precipitate, resulting in urinary tract stones.
Why should spinach be blanched.
Whether spinach is used to make soup, cold dressing, or single stir-frying, it should be blanched first. This is because spinach has the highest oxalic acid content of any green vegetable, with a whopping 606 mg of oxalic acid per 100g of spinach.
Oxalic acid not only makes spinach taste very astringent and affects the taste, but also combines with calcium in the body to produce calcium oxalate crystals, which can cause calcium deficiency in mild cases and even urinary tract stones in severe cases. Oxalic acid is easily soluble in water, so it is recommended to blanch spinach in advance.

Why blanch spinach before eating?

Spinach is to be blanched and eaten. Spinach has a high oxalic acid content, and oxalic acid is easy to combine with the calcium eaten by the human body to form insoluble calcium oxalate, which can not only not be absorbed and utilized by the human body, but also hinders the absorption of calcium by the human body. Therefore, when eating spinach, it should be blanched with water.
Oxalic acid is relatively soluble in water, and 80% of the oxalic acid in spinach will be removed if soaked in hot water for 2-5 minutes.
Because spinach contains an oxalic acid, which can be removed with high temperatures. If this oxalic acid is not removed, calcium oxalate is easy to form in the body, causing stones, so it must be cooked before eating, and it cannot be eaten with foods that contain a lot of calcium, such as milk and tofu.
In fact, calcium oxalate will still be excreted and metabolized in the body, not to mention such a trace amount of calcium oxalate. Some places say that calcium oxalate will accumulate in the kidneys and form kidney stones, in fact, such a small amount of calcium oxalate has not accumulated and has been metabolized by the body, and there is no need to worry about accumulation.

Spinach is a relatively common vegetable, which can be fried and eaten, can also be made into soup to eat, people say that spinach to blanch, so spinach is not blanched to eat harmful?
Spinach 1 Is it harmful to eat spinach without blanching.
There is a certain impact.
Spinach is a vegetable that contains a lot of oxalic acid, and its content is about about that, oxalic acid itself is harmless, but oxalic acid will react with calcium in the body to form calcium oxalate.
When eating spinach, part of the oxalic acid will react with the calcium in the small intestine to produce calcium oxalate precipitate, which is difficult for the stomach and intestines to dissolve, digest and absorb calcium oxalate, so it will be deposited in the body and cause stones.
Although spinach is not blanched and eaten has a certain impact on the human body, these are based on a long-term basis. Hot water can remove 50%-80% of the calcium oxalate in spinach, so for your own health, it is best to blanch spinach once.
2 What should I do if I don't blanch the fried spinach and eat it.
It's okay once in a while, but not for a long time.
If you don't blanch spinach when you fry it, it doesn't matter if you eat it once or twice, there is no toxic substance in itself without blanching, and the calcium oxalate content generated is relatively small, and it has little impact on human health, so it does not need to be treated.
If you eat spinach without blanching for a long time, there may be stones in the body, it is recommended that if you have uncomfortable symptoms, it is recommended to seek medical attention in time and relieve it under the doctor's examination**.
3 How to store blanched spinach.

1. Spinach contains oxalic acid, and oxalic acid will combine with free calcium ions in the body to form calcium oxalate crystals, so we generally recommend blanching to remove oxalic acid when eating spinach.
2. Although oxalic acid is easily soluble in water, it will not decompose due to heating, so when blanching spinach with boiling water, it will not decompose oxalic acid, but dilute it.
3. When making spinach soup, if you directly cook the spinach soup and drink it with the soup, it is equivalent to not reducing the intake of oxalic acid, which is only dispersed into two places and enters the human body. After removing the blanching water after blanching, the oxalic acid content of spinach decreased greatly.

Summary. Hello, spinach is harmful if eaten without blanching. Since spinach contains a lot of oxalic acid, which will nourish stomach bloating and kidney function, it is recommended to blanch spinach for two or three minutes before eating.
Oxalic acid will react with calcium, and long-term consumption will cause calcium loss, or turn into calcium oxalate, forming urinary stones and other diseases. Spinach should be cooked thoroughly before eating. If it is cold spinach, it also needs to be blanched before eating.
Hello, Hail Rock sells spinach if it is not blanched and eaten is harmful. Since spinach contains a lot of oxalic acid, which will nourish stomach bloating and kidney function, it is recommended to blanch spinach for two or three minutes before eating.

Spinach should be cooked thoroughly before it can be eaten. If it is cold spinach, it also needs to be blanched before eating.
The purpose of blanching spinach is generally to remove oxalic acid in spinach, and if a small amount of spinach is not blanched, it will generally not cause the body to have a good reaction. However, long-term excessive consumption may lead to excessive intake of streptooxalate in the body, which is easy to form insoluble calcium oxalate after combining with calcium, thereby affecting the body's absorption and utilization of calcium. Spinach is rich in vitamin K, carotene and vitamin A and other nutrients, moderate consumption can promote gastrointestinal peristalsis and help the body better absorb the nutrients in food.
Precautions: It is recommended to cook spinach in hot water before eating, which can effectively reduce the intake of oxalic acid in the body.

Yes. Spinach is unique in that it has a high oxalic acid content, which is probably around the limit. Oxalic acid is not scary, it is the beginning of the nightmare when it enters the body.
In the small intestinal fluid, most of the oxalic acid will combine with calcium ions to form calcium oxalate. This substance has a very low solubility and slowly settles down in the kidneys, leading to urinary tract stones. Therefore, from a health point of view, it is best to blanch spinach in advance.
Precautions: Spinach vs. cucumber: The vitamin C in spinach is destroyed by the breakdown enzymes in cucumbers.
Spinach and tofu: The oxalic acid in spinach and the calcium in tofu form calcium oxalate, which makes the body's calcium unable to absorb.
Spinach and milk: Eating together can cause dysentery.
Spinach and eel: Eating together can cause diarrhea.
Spinach and leeks: Eating the two together has a sliding effect and is easy to cause diarrhea.

If you eat too much spinach, it may cause indigestion and gastrointestinal discomfort, so spinach must be eaten in moderation. So should spinach be blanched? Can you eat spinach without blanching?
Whether the spinach should be blanched.
Stir-fried spinach needs to be blanched, and the general blanching time is 1-2 minutes. Spinach contains oxalic acid, which, if combined with calcium ions in the human body, will produce calcium oxalate, which is not easily absorbed by the body and can even hinder the body's absorption of calcium ions. However, oxalic acid can be dissolved in boiling water, so spinach is generally blanched in boiling water first.
Can you eat spinach without blanching.
It can be eaten, but it is not recommended to eat it in large quantities for a long time. In ordinary life, many people do not blanch spinach before cooking and eating, and it is generally okay to eat a small amount, especially for people with normal digestion and good health, because the absorption rate of oxalic acid in the intestine is not high, and a small amount of oxalic acid is generally not much affected after being absorbed. It is recommended to drink more water, which can dilute the concentration and help prevent the occurrence of urinary tract stones.
In addition, for people who have urinary tract stones, then they need to be cautious about eating, because the utilization rate of oxalic acid in people with urinary tract stones is higher than that of normal people, and eating may aggravate the condition, so it is recommended that people with urinary stones eat spinach in moderation.
How should spinach be blanched.
1. Clean the spinach, remove the residual leaves, and wash it repeatedly with water.
2. Pour an appropriate amount of water into the pot, boil the water over high heat, then add a spoonful of cooking oil and white sugar mixture to the pot, stir quickly and then add spinach.
3. After the spinach is put into the pot, continue to blanch the water over high heat, and wait until the water boils again, you can take out the spinach, and then quickly put it into the cold water to cool for a while, the taste will be more crisp, and the color will remain more green.
What to pay attention to when blanching spinach.
1. It is recommended to open the lid of the pot during blanching, which can help spinach keep it green, because spinach will release organic acids in the process of heating, which is the main substance that promotes the discoloration of vegetables. But blanching the pot with the lid open can prevent the spinach from turning yellow.
2. The blanching time should not be too short, otherwise it will not be blanched, and the purpose of inactivating the phenolase will not be achieved, but it will promote the browning of vegetables. Similarly, blanching for too long can make the vegetables dull, tarnishing, and the green pigment decomposes too much. Blanching time must be controlled and shortened.
Yes, spinach should be blanched in advance.
