1. If you don't eat coarse grains, your face will turn yellow.
Nowadays, many children are reluctant to eat coarse grains, which are rich in fiber and have a bad taste and are not easy to accept. Some parents even think that eating polished rice and white flour is a sign of improving living conditions. As for children, many people don't even know what coarse grains are. However, with the long-term exclusion of coarse grains and eating only flour and rice, a large number of children suffer from hypertension and diabetes. Why is this? As we all know, food is accompanied by the loss of vitamins and other nutrients, and the loss of some essential trace elements is also obvious. After wheat is refined into rich flour, only 20% of magnesium, 13% of chromium, 12% of manganese, 50% of cobalt, 37% of molybdenum and 2 1% ~ 3 1% of zinc in the original wheat are retained. Brown sugar is a traditional folk food in China, which contains chromium and various trace elements, while refined white sugar is not only extremely low in nutrients such as trace elements, but also stimulates the excretion of chromium in urine. Insufficient long-term intake of trace element chromium can increase the incidence of diabetes and coronary heart disease. It can be seen that the view of "not eating enough" is not desirable.
Nowadays, many people don't eat polished rice or buy rich flour steamed bread. As a result, the child's rice is white, but his face is yellow. Interestingly, while our staple food has changed from coarse to fine, developed countries are striding backwards-returning to coarse grains from flour and rice. German whole wheat bread sells well; In Japan, the aroma of baked sweet potatoes is very heavy and floats on the streets of the city; New Zealand's "eat miscellaneous staple food with peas and broad beans" has become the call of the government; The United States puts whole wheat bread at the bottom of the "food guide pyramid". International nutritionists put forward that "light diet and balanced calories are the key to longevity", which is similar to the "people who eat iron but don't eat" in China.
Coarse grains include millet, yellow rice, barley, buckwheat, corn, sorghum, highland barley, soybean, edamame, broad bean, mung bean, adzuki bean, pea, potato, sweet potato, yam, chestnut, water chestnut, peanut and sesame. In the past, dietary fiber contained in coarse grains was once considered as a component with no nutritional effect on human body. In 1970s, western nutritionists realized that dietary fiber in coarse grains was closely related to human health and played an important role in preventing some diseases. For example: intestinal cancer, appendicitis, constipation, hemorrhoids, diabetes, heart disease, hypercholesterolemia and obesity. At the same time, I also realized that the concept of crude fiber is no longer applicable, so I gave up the term and renamed it dietary fiber. The repeated choice of staple food in western developed countries tells us that instead of hitting the "south wall" and then "turning around", it is better to pay attention to adhering to the diet structure of the Chinese nation in order to benefit children's health.
2. Excessive sweets "only take its palatability, and the yin suffers from it."
Western Europe and Americans consume about100g of sucrose every day, and people are very concerned about the impact of sugar on health. Although the safety of sucrose is recognized, excessive sucrose can lead to obesity and chronic diseases. The intake of sugar should not exceed 10% of the total calories of food, and should be controlled below 60 grams per day. As we all know, insulin can induce the synthesis of coenzyme with catalytic effect in cells. If you eat too much sugar, the remaining glucose is converted into fatty acids in cells with the help of insulin, and then fat is synthesized. Adipose tissue is distributed under the skin and inside and outside various organs, and finally it is inevitable to escape from the fetters of obesity.
Many children like eating candy and drinking drinks. These foods are high in sugar, and eating too much will inevitably affect the dinner. Humans are naturally fond of sweets, and some children even chew sugar to sleep. Not only is it not conducive to dental care, but high-sugar diet is also easy to make protein saccharify and deteriorate, causing nerve damage, weakening intelligence and accelerating brain aging. Children who are used to a high-sugar diet have poor intelligence test scores and are emotionally unstable. The survey shows that the proportion of sucrose in diet is negatively correlated with academic performance and IQ, and the diet with low nutrition and high sucrose has obvious adverse effects on learning. Therefore, as Li Shizhen, a medical scientist in the Ming Dynasty, said: Too much sweets will inevitably lead to "only taking its palatability, while Yin will suffer"!
3. Hypertension induced by "heavy mouth"
At the medical conference held in Frankfurt, Germany, salt was accused as a "secret killer". In industrialized countries, more people are sent to their graves by salt instead of harmful chemicals. Hypertension and its related diseases such as myocardial infarction, atherosclerosis and stroke are all related to "heavy mouth"-eating too much salt. Therefore, changing the eating habit of "heavy mouth" is an important measure to control hypertension.
According to the survey in 2002, the prevalence of hypertension among people aged 35-74 in China has reached 27.2%, and there are about 65.438+300 million hypertensive patients in this age group alone! The results of national hypertension sampling survey in 1980s showed that the number of patients with hypertension increased by 654.38+100000 every day. The prevalence of hypertension in the whole country showed a significant downward trend from north to south. The prevalence rate of hypertension in big cities Beijing > Tianjin > Shanghai > Guangzhou is 4.4 times that in Guangzhou. The data show that the average daily salt intake of Chinese residents is 13.5g, which is obviously too high compared with the standard of less than 5g per person per day stipulated by the World Health Organization. Compared with Shandong, which has the highest salt intake (average 17.3g), and Guangxi, which has the lowest salt intake (average 7.5g), the prevalence of hypertension in the two places is nearly doubled, being 15.3% and 8.2% respectively. In China, salt restriction was observed in 50 patients with essential hypertension. The results showed that the diastolic blood pressure of 10 patients decreased by more than10mmhg when the daily salt content was limited to 4g. For patients with essential hypertension, salt restriction is indeed a very simple and effective preventive measure. If the salt intake can be reduced to 5-6 grams per person per day, hypertension and cardiovascular diseases can be significantly reduced.
"Five flavors are harmonious and impartial." How much salt do Shandong farmers eat a day? Eating 17.8 grams of salt, the incidence of hypertension in Shandong farmers is 1 1.8%. Farmers in Guangxi eat 7.5 grams of salt a day, and the incidence of hypertension is 8.2%. Eskimos living in the Arctic Circle eat 4 grams of salt every day, and the incidence of hypertension is only 4%. In Akita, Hokkaido, Japan, because of the habit of eating salted fish and eating 26 grams of salt a day, the incidence of hypertension reaches 28%, so the amount of salt eaten is directly proportional to the incidence of hypertension. Generally speaking, when cooking, the salt content in the dish is 1%. In fact, the taste of salt is formed by habit, and the eating habit of "heavy mouth" can be changed. Therefore, developing a correct eating habit of "speaking softly" from an early age will benefit children for life.
4. The teeth are messy and the roots are eating.
More and more primary and middle school students go to the stomatological hospital for orthodontics. Many people can't help asking: Why are there so many children who correct their teeth now? There are many reasons for malocclusion of teeth, which can be summarized as genetic factors and environmental factors. According to clinical statistics, genetic factors account for 29%, and environmental factors account for 7 1%. The deterioration of masticatory function is one of the main reasons. Once a parent came to see a doctor with a one-and-a-half-year-old child. The reason is that babies can't chew until now. After asking, I found that parents thought Heinz baby food was expensive aristocratic food, so they let their children eat only various cake-like Heinz baby food from an early age. Because children have never eaten natural food, they don't start chewing until they are nearly one and a half years old.
Nowadays, children's food is becoming more and more exquisite. Because of eating a lot of refined foods such as dairy products, bread and puffed food, children are more and more lazy to chew hard things, which makes their chewing function weaker and weaker, which makes the muscles inside and outside the mouth unable to get proper exercise and the jaws unable to develop well. Because the number of teeth has not decreased, the incidence of malocclusion is getting higher and higher. Fine food is also easy to induce dental caries, resulting in tooth defects, leading to premature loss of deciduous teeth, resulting in insufficient eruption gap of permanent teeth, resulting in uneven arrangement of children's teeth.
