Can jujube invigorate blood treat anaemia? Announcement of iron food ranking

in life, people often say that jujube can cure anemia. Is it true?

What is anaemia? How to treat anaemia?

According to the World Health Organization, anemia is diagnosed when hemoglobin is lower than the following value:

≪ 110g / L for 6-year-old children, 120g / L for 6-14-year-old children, 130g / L for adult men, 120g / L for adult women and 110g / L for pregnant women. See Table 1 for specific standards:

Hemoglobin is the main component of red blood cells, which is composed of iron ion and globin. There are abundant protein in human body, but the content of iron is limited. The problem of anemia mostly lies in iron ion.

Iron ions, the main raw material for hemoglobin synthesis, come from food and are absorbed through the digestive tract; red blood cells are synthesized in the bone marrow with an average life of 120 days, and the aged red blood cells are destroyed in the spleen. This is a complete life process of red blood cells. If there is any problem in any link, anemia will be caused.

The common causes of anemia are: iron deficiency, bone marrow disease, chronic blood loss, slow consumption disease, etc. The treatment of anemia, in addition to the treatment of primary disease, need to supplement iron ions. That is to say, iron can replenish blood. The so-called blood tonic therapy and treatment of anemia is to supplement iron ions. If the food is supplemented, the higher the iron ion content and the better the absorption of food, the better the effect of blood supplement.

II. Iron food ranking

Ranking of iron content of common foods (unit: mg / 100g food)

Note: the data are from the second edition of Chinese food ingredients list

Please note that the iron in animal food is heme iron, the absorption rate is as high as 22% - 25%, while the iron in plant food is inorganic iron, the absorption rate is only 1% - 5%. Although some plant foods contain high iron content, their absorption is very poor, so iron supplement mainly depends on animal food.

Can jujube mend iron?

From the above ranking of iron content, we can find that the iron content of every 100g of dried jujube is only 2.1mg, only 1 / 6 of the iron content of dried cabbage. Other dates, such as jujube 2.7, honey 3.5 and sour 6.6, also exceed the iron content of carrots. The iron content of these jujubes is very low, and the absorption of iron in jujube is very poor. If you use jujube to make up iron, see how to make up.

It is known that a healthy pregnant woman needs 35mg of iron every day. If the dry date alone is used for iron supplement, the iron content of 100g of dry date is 2.1mg. According to the highest absorption rate of 5%, 35 & pide; 2.1% & pide; 5% = 33333.33g = 33.3kg. As a result, a pregnant woman needs to eat 33 kg of dried jujube every day to meet the requirement of iron supplement. 33 kg a day! If you don't burst your stomach, your brain will be damaged, and you will also eat serious diabetes.

Baidu said: the nutritional value of red jujube is quite high, although the iron content is not high, but it contains a lot of vitamin C and a, and every 100 grams of red jujube contains 500 mg of vitamin C. Therefore, the puerpera should eat the food rich in vitamin C while eating the food containing iron. Red dates are the best supplement.

This word has certain truth, but Baidu about the red jujube vitamin C content is not very accurate, should contain vitamin C243 mg per 100 grams of red jujube, and refers to fresh jujube. If it's dry jujube, it only contains 7 mg vitamin C per 100 g.

Take fresh jujube rich in vitamin C for example, although it can't supplement iron, it can help supplement iron. Vitamin C, citric acid and malic acid can transform the trivalent iron in food into bivalent iron and promote the absorption of iron. But jujube can do it, and other vegetables and fruits rich in vitamin C can do it. So, jujube is only a good partner for iron, but not the only good partner.

IV. which food is the best iron supplement

The foods with high iron content and common use include animal liver, lean meat, fish, blood, egg yolk, etc., black fungus, soybean, millet, green leafy vegetable in plants, kelp and laver in marine products, etc., which can be used to supplement iron.

In addition, children can choose to supplement iron with iron fortified food specially added with iron agent, which is specially indicated on the label.

Milk is an alternative to iron. The iron content of milk is very low, and the calcium in it is easy to produce compounds with iron, but it is not conducive to the absorption of iron. Therefore, milk can not supplement iron, and it is more appropriate to eat iron supplement food 2 hours after drinking milk.

Kiwifruit, citrus, orange, tomato and other fresh fruits and vegetables rich in vitamin C, citric acid and malic acid can promote the absorption of iron, and also can help supplement iron. However, calcium, tannin and other substances can be combined with iron to form compounds that are not absorbed, thus hindering the absorption of iron. Therefore, calcium and iron agents should not be taken together. Children and anemia should avoid drinking strong tea.

Finally, I declare that jujube is a good food, and I have absolutely no intention of slander, but wrong understanding of jujube, putting the treasure of treating anemia on it will delay your illness, that's all.
