In life, some people often put some alkali in the porridge when cooking white rice porridge, especially the chefs in the canteen like to do so. On the one hand, the picture shows that it is cooked quickly, on the other hand, the porridge cooked after adding alkali is more sticky and fragrant, and tastes good. However, they don't know that this will destroy the most precious nutrients in rice (rice and millet), such as vitamin B 1 and vitamin B2. Moreover, because vitamin B 1 is called a mental nutrient, it has a very important influence on nervous tissue and mental state, and it can also cause symptoms such as fatigue, forgetfulness and anxiety when it is insufficient. Therefore, boiled white rice porridge must not add alkali.
Except for one case, it is to cook corn.
When making corn products such as porridge, corn paste and wowotou, a small amount of alkali should be added. This is because the content of nicotinic acid in corn is very high, but 63% ~ 74% of it is bound nicotinic acid that cannot be absorbed and utilized by human body. Long-term consumption of this corn food may cause niacin deficiency-pellagra: dermatitis, diarrhea, dementia. The initial symptoms include laziness, loss of appetite, chapped lips, red tongue and pain. If the disease continues to develop, it will cause dermatitis on the skin in the sun, and the skin on the face, hands and feet will have symptoms such as redness, blisters, peeling, brown pigment precipitation, roughness and wrinkles. In order to avoid this situation, the best way is to add some alkali to corn food, that is, when cooking corn porridge, corn batter and making corn bread, put some alkali in moderation. In this way, the combined nicotinic acid in corn can be released into free nicotinic acid, and the release rate of nicotinic acid in corn food containing alkali can reach 37% ~ 43%, and vitamin B 1 and vitamin B2 can be preserved, which is very beneficial.
Supplement zinc, eat more steamed bread and less rice.

Nowadays, many parents attach great importance to zinc supplementation for their children and blindly eat various supplements and health products. But they don't know why children lack zinc, how to judge children's zinc deficiency and how to supplement zinc. This edition interviewed relevant industry experts and answered them for you.
From June 5438 to1October 7, 2005, the data of "Investigation on the Health Status of Children Aged 0-6 in Ten Cities of China" jointly published by the Office of the State Council Women and Children Working Committee and China Children Center showed that the zinc deficiency rate of children reached 39%.
On April 3, 2005, the Maternal and Child Health Hospital in the four districts of Changsha conducted an investigation on 1600 children aged 0-3. The results showed that 63.7% children were zinc deficient.
On June 26th, 2002, a survey of 3000 children aged 3-5 in Nanjing Maternal and Child Health Hospital showed that 3 1% children were zinc deficient.
Professor Dai, director of the Children's Health Cooperation Center of the World Health Organization, said that the survey data will be more or less inaccurate because the detection methods and standards of zinc in society are still not uniform. But what is certain is that zinc plays an important role in children's growth and development and should be paid attention to.
Rice is an important cause of zinc deficiency.
In the interview, the reporter found that many parents are confused about their children's zinc deficiency. "Now the standard of living is not low, children eat well and wear well. How can they be short of zinc? "
Dr. Chai Yuli from the Biomedical Research Center of Weill Biomedical Group in the United States explained that staple food is an important reason for this situation. It is the habit of most people to take rice and noodles as staple food, but in fact, there is a substance called phytic acid in rice flour, which can combine with zinc to form a compound, which makes the human body unable to absorb it normally, leading to zinc deficiency, which will affect the normal development of children.
However, there is another characteristic of phytic acid in staple food. If fermented, phytic acid will be reduced, which will no longer affect the absorption of zinc. Therefore, eating steamed bread and bread is more beneficial to zinc absorption than eating rice.
In China, the eating habits of the north and the south are different, so we can see a clear contrast: northerners who are used to eating steamed bread are relatively tall, while southerners who are used to eating rice are relatively short, which is related to zinc intake to some extent. Another survey shows that westerners who eat bread are relatively less deficient in zinc.
Children who are picky eaters are prone to zinc deficiency.
Although rice and noodles have a lot to do with children's zinc deficiency, they can't all be attributed to this. If the child doesn't eat enough, even if it is completely absorbed, it is difficult to reach the normal level. Professor Dai told reporters that some children are very picky about food, especially those who don't like meat. They consume too little zinc, which makes them vulnerable to zinc deficiency.
Professor Dai explained that some parents' misconceptions can also lead to zinc deficiency in children. For example, the liver of animals is a food rich in zinc, but some parents think that the liver is an organ for detoxification, so it must be toxic, so children are not allowed to eat it, which in turn affects zinc intake.
In addition, Professor Dai mentioned a point that was easily overlooked by parents. Children who grow too fast are also prone to zinc deficiency. Zinc is an important element to promote height growth. If a child grows too fast, the demand for zinc will increase greatly. If it cannot be replenished in time, it will naturally lead to zinc deficiency.
Zinc supplementation requires adequate intake first, and then ensures absorption.
Zinc supplementation must first ensure a balanced diet and diversified intake. Professor Dai said that this is the basic principle to solve the problem of zinc deficiency in children. Animal offal, lean meat, fish, shellfish and other seafood are all foods rich in zinc. In addition, egg yolk and nuts should be eaten more, so as to fundamentally ensure adequate zinc intake.
Of course, after taking enough, try to ensure more absorption. Therefore, Dr. Chai suggested that in addition to rice, we should eat more fermented foods, such as bread, steamed bread and other pasta. We should also increase the intake of dairy products, because dairy products do not contain phytic acid, which will not affect the absorption of zinc and strengthen nutrition. For weaned children, when adding complementary food, you can try the method recommended by Dr. Chai: feed the children with bread soaked in milk.
Professor Dai suggested that you can go to the hospital regularly to check trace elements for your children. Once the child is found to be zinc deficient, zinc should be supplemented under the guidance of a doctor. Because this medicine needs to be taken at the right time and dose, you can't eat it casually. For example, zinc should not be taken immediately after meals, otherwise it may be combined again, thus losing the significance of supplementation. Professor Dai also stressed that it is best not to buy health care products to eat by yourself. Because the zinc content in health care products is low, it is difficult to play a supplementary role, and the related products on the market at present are too miscellaneous, and some of them are difficult to guarantee in quality. ▲

How to judge children's zinc deficiency
2005- 1 1-24 10:20:30
At present, there are two methods to check zinc internationally. One is to use hair test, called hair zinc; The other is called blood zinc, which is detected by blood sampling. However, because these two methods may be affected by the external environment, such as the pollution of acquisition instruments, they will all produce certain errors. Therefore, at present, the standard for accurately judging zinc deficiency is the test result plus the observed symptoms. Usually zinc deficiency will occur as follows:
1, loss of appetite. Children generally eat less, some don't feel hungry and don't take the initiative to eat.
2. Eat strange things. Such as biting nails, clothes, eating toys, hard objects, eating hair, scraps of paper, raw rice, wall ash, dirt, sand and so on.
3. Not high. For babies under one year old, parental observation is very important because they have no expressive ability. The first peak of height growth is when the child is less than one year old, and it will increase by at least 2-3 cm every month. It will grow 4-5 cm in the first half of the year or even every month. Therefore, parents can initially judge whether there is zinc deficiency by monitoring their children's height.
4. Hair grows slowly. This is often overlooked by parents. For example, some children don't care if their hair grows for half a year, which is probably caused by zinc deficiency.
5. There are white spots on the nails, long barbs on the fingers, and a map tongue (irregular red and white patterns on the tongue surface).
6, hyperactivity, slow response, inattention, poor learning ability.
7, particularly vulnerable to virus attacks. For example, frequent colds and fever, repeated respiratory infections, such as tonsillitis, bronchitis, pneumonia, hyperhidrosis, night sweats and so on.
8. Recurrent oral ulcer.
However, a single symptom should not be used as a criterion, and whether a child is zinc deficient should be considered comprehensively. For example, poor appetite is not necessarily zinc deficiency, because this anorexia may also belong to anorexia nervosa. Only when accompanied by other symptoms, it may be zinc deficiency, and it is necessary to go to the hospital for examination in time. ▲(
