Chinese height lower than that of Japan and South Korea: people are doing-IT information
A few days ago, the British Empire, led by the Institute of international research team published the height of a global population of more than 200 countries report, this "world height ranking" recorded the height during the 1914 to 2014, the report shows, in 2014, the Netherlands male 182.54 cm tall on average, highest in the world. While in Japan, and Korea and China three height according to highest for men and women are Korea, 174.92 and 162.34 cm respectively, Chinese male and female average height of 171.83 cm and 159.71 cm respectively, compared with Japan about 1 cm high.
But behind the data in this list, there is a truth, that is, height growth rates. Korea and Japan men ranked "was the most" list of men in the third (15.17 cm) and fifth (14.65 cm). Compared with China, men increased by only 11 cm in height, females was 9.6 cm.
Indeed, in the past 100 years, most countries like China in the "tall", but with Japan than China apparently grow more slowly, more height growth in the world's first Miss Korea. Among them, the height growth of the Japanese by Western scholars as the "human development." Japan and South Korea grew faster what tips are there?
Shanghai Institute of physical education College of sports science tutor, expert Lu Dajiang analysis on students ' physique in Shanghai in recent 20 years in China and Japan teenagers height data showing that, in population genetic gene is not a fundamental change in circumstances and acquired factors play an important role. And acquired factors, diet, exercise, and sleep is an internationally recognized impact on growing the three most critical factors.
Break milk and nutritional lunch
After World War II, Japan set off "a glass of milk and strong nation" campaign. Japan for students in primary and middle schools feeding with milk. This is Japan famous "milk plan".
Today, Japan every day rain or shine to drink a glass of "milk break". Every morning around 10, Japan children from kindergarten to third grade, to drink a glass of fresh milk, different ages drink, ranging from 200 ml to 400 ml.
Lu Dajiang said, milk is a very good source of calcium, and calcium to phosphorus ratio is appropriate, conducive to the absorption of calcium. Kids per day guarantees a certain amount of milk intake, calcium does not lack, laying a solid nutritional foundation for tall.
In addition, Japan was enacted in 1954, the school feeding Act, clear nutritious lunches to improve students ' health goals, also stipulates that school feeding is also a part of compulsory education. Lu Dajiang, Japan "height" of poverty and childhood obesity rate is the lowest in the world, which have benefited from years of nutritious lunch system. "Japan student lunch recipes developed by the school dietitian, eating the kinds of foods there are 30 or so a day, and every day is the same. ”
And Japan compared to our traditional diet of three dinners are just two dishes and one soup, Japan domestic food samples every day in the 25-30, of course, than the Chinese more than more than 10 a day things get much more nutrient rich.
Xiangshan in the hospital TCM medical physician, and Shanghai first "children encourages TCM outpatient" head Qian Shangtong has years TCM encourages experience, in clinical diagnosis in the he found, was short of children General Eclipse, currently domestic parents are of awareness status also does not conducive to children growth, even domestic of school also provides nutrition lunch, can many children no seriously to put nutrition lunch eat finished, parents also does not and school active tie, instead afternoon school Shi will to children with small snack, and snacks. "This habit is not conducive to the growth of children, parents with schools, encourage students to accept the overall nutritional lunches. "Qian Shangtong said.
Lifelong exercise habit
In Japan and Korea, and baseball are the main national sport. Baseball has long been loved by the Japanese sports, nearly all Japan men have played. Japan baseball standard is always in first-team in the world category.
According to foreign institutions survey: Baseball not only energetic, more high level of IQ, EQ, better able to adapt to the fierce competition in the future society. While baseball is typical of the sport of running, jumping, throwing a comprehensive development, highly conducive to promoting the growth and development of young people.
"Children have a love of sports, and stick to it, is very good for long. "Lu Dajiang said Japan students ' basic habit of lifelong exercise habit, this is because they have one or two myself very good at sport and exercise motivation is very high. And Japan the education community has a lot of moves in the game plan, so that children are playing in the process of getting a good workout.
And China's current situation is generally not the specialist sports, combined with the enormous pressures, students have a degree of active sports weakened, even stressed now 1 hour a day of exercise, Lu Dajiang, time standards, but the real meaning of exercise effect is unsatisfactory.
Lu Dajiang Japan study on the physical fitness of students in 11 years, he had seen Japan after 3 o'clock in the afternoon the students have remained largely academic until dinner time before Japan students usually are used for locomotion. And Japan very strong interaction between parents and children, every weekend, Japan parents generally participate in a parent-child, the whole social atmosphere are quite strong.
Three hungry and cold
Winter no matter how cold it is, Japan's child was wearing down, and be sure that only one knee-length shorts, legs so the children exposed to the wind, this picture is Japan students typically dress up in the winter, Japan mothers generally reflect, after the cold training, the number of child less.
Although Japan's approach is a bit exaggerated, but in the eyes of Qian Shangtong since ancient times, China has "to children, bring a copy of hunger and cold" parental teaching, Japan child winter clothing is also meet this concept-the Center is not a cold, cold stimulus of lower limbs.
"Cold stimulates growth hormone release. "Qian Shangtong further explained road, children growth of key is growth hormone, and let children some cold of feel will can prompted human itself release growth hormone," certainly I advocates of is give children appropriate of cold stimulus, and not has been let children in cold of environment in, like now fall don't added clothes too fast, if children in season process in the no feel to cold, lack cold stimulus, regardless of on growth also is respiratory are not is good. "The worrying reality is that Chinese parenting concepts common to the children too much.
Also, according to Qian Shangtong introduced, hunger sense helps growth, thus Qian Shangtong always told children of parents in guarantee children meals nutrition intake balanced of based Shang, no necessary every now and then to children snack and snack, from TCM angle told, people of spleen and stomach has a work and rest alternating of process, if no hunger sense, spleen and stomach have not to rest, not only children long not high, even will led to obesity.
Let the children fell asleep before 21 o'clock
Vital part of sleep are also contributing factors. Qian Shangtong treasure 9 o'clock to 6 o'clock in the morning hours of sleep, he stressed that, in order to guarantee young people's height, 9 o'clock in the evening to turn off the lights to sleep. Preschool children to sleep 10 hours, teenagers to sleep 9-10 hours.
Why sleep at this time is more conducive to growth? This is because human 80% growth hormone is secreted at night. From the curves of growth hormone secretion is evident, after 10 o'clock is the secretion of growth hormone to achieve the peak of the day, can reach the day of 5-7, from 5 o'clock in the morning to 6 o'clock, there will be a peak growth hormone secretion. "Sleep is deep, if it is 9 o'clock in the evening to sleep, light sleep 1 hour, until 10 o'clock has entered a deep sleep also can peak and growth hormone secretion in synchronization. "The Commission said.
中国人身高增长比日韩低：人家是这样做的 - IT资讯
日前，英帝国理工学院率领的国际研究团队发布了一项针对全球200多个国家人口的身高报告，这份“全球身高排行榜”记录了1914年至2014年期间人们的身高，报告显示，2014年，荷兰男性平均身高182.54厘米，为全球最高。而在日本、韩国和中国三个国家的身高数据显示，男女最高均为韩国，分别为174.92厘米和162.34厘米，中国男性和女性平均身高分别为171.83厘米和159.71厘米，均比日本高约1厘米。
不过在这个排行榜数据背后，还有一个真相，那就是身高的增长速度。韩国和日本的男性分别位列“长得最快”的男性榜单中的第三（15.17厘米）和第五（14.65厘米）。相较中国，男性身高只增长了11厘米，女性为9.6厘米。
诚然，在过去100年，多数国家像中国一样在“长高”，但与日本相比，中国明显长得慢，更赶不上身高增速全球第一的韩国。其中，日本人的身高增长被西方学者誉为“人类体质发展奇迹”。日韩长得快究竟有何窍门呢？
上海体育学院运动科学学院研究生导师、上海市学生体质研究专家陆大江分析，近20年中国和日本青少年身高数据证明，在族群遗传基因未发生根本变化情况下，后天因素起重要作用。而后天因素中，饮食、运动和睡眠是国际上公认的影响长高最关键的三大因素。
课间奶和营养午餐
二战后，日本掀起“一杯牛奶强壮一个民族”的运动。日本在中小学供餐中为学生提供牛奶。这也就是日本有名的“牛奶计划”。
如今，日本学生每天雷打不动要喝一杯“课间奶”。每天早上10点左右，全日本从幼儿园到初三年级的孩子，都会喝到一杯新鲜的牛奶，年龄不同喝的量不同，从200毫升到400毫升不等。
陆大江表示，牛奶是人体钙的非常好的来源，且钙磷比例非常适当，利于钙的吸收。孩子每天保证一定量的牛奶摄入，确实不会缺钙，为长高打下坚实的营养基础。
此外，日本于1954年颁布了《学校供食法》，明确营养午餐增进学生健康的目标，更规定了学校供餐也是义务教育的一环。在陆大江看来，日本的“身高”脱贫，且儿童肥胖率在世界上也是最低的，这都受益于多年实行的营养午餐制度。“日本学生的午餐菜谱由学校专门的营养师制定，每天吃的食物种类有30种左右，并且每天都不相同。”
和日本相比，我们传统饮食三口之家晚餐也就只有两菜一汤，而日本家庭每天保证食品样数在25-30种，这当然比中国人一天只吃十多样东西获取的营养要丰富得多。
香山中医院中医内科主任医师、上海首家“儿童助长中医门诊”负责人钱尚统有着多年中医助长经验，在临床诊断中他发现，个子矮小的孩子普遍偏食，目前国内家长们的认识现状也的确不利于孩子生长，即使国内的学校同样提供营养午餐，可不少孩子没有认真地把营养午餐吃完，家长也并不与学校积极配合，反而下午放学时会给孩子带小点心、零食。“这样的习惯并不利于孩子的生长，家长应配合学校，鼓励学生接受全面的营养午餐。”钱尚统坦言。
终身锻炼习惯
在日本和韩国，棒球都是国民的主要运动。棒球，一直以来是日本人酷爱的体育项目，几乎所有的日本男人都玩过。而且日本棒球水准始终处于世界一线球队范畴。
据国外相关机构调查：打棒球的学生不仅精力充沛，智商、情商水平更高，更能适应未来社会的残酷竞争。同时棒球又是典型的跑、跳、投全面发展的体育运动，对促进青少年生长发育极为有利。
“孩子有一项热爱的运动，并能坚持下去，对长个子非常有好处。”陆大江坦言，日本学生基本养成了终身体育锻炼的习惯，这正是缘于他们有一到两项自己非常在行的运动，因而锻炼积极性非常高。且日本教育界也有很多将运动融入游戏的方案，这样孩子们在玩的过程中便得到了很好的锻炼。
而中国的现状是学生普遍没有特长的运动项目，加之巨大的升学压力，学生们对体育的积极程度相对减弱，即使现在强调每天1小时锻炼，在陆大江看来，时间可能达标了，但真正意义上的锻炼效果却是不尽如人意的。
陆大江在日本研究学生体质的11年时间中，他看到，日本学生下午3点后基本没有课业，直到晚餐前的时间日本学生们通常都用于运动。且日本家长和孩子的互动性非常强，每到周末，日本的家长普遍会参与到亲子运动中，整个社会的运动氛围都相当浓郁。
三分饥与寒
冬天无论多冷，日本的孩子即使上身穿着羽绒服，下身肯定只有一条及膝短裤，孩子们的双腿就这么暴露在寒风中，这样的画面可谓是日本学生冬日的典型打扮，日本的妈妈们却普遍反映，经过这样的寒冷训练，孩子得病的次数反而少了。
虽然日本的做法有些夸张，但在钱尚统看来中国自古便有“若要小儿安，带一份饥与寒”的育儿古训，而日本孩子冬日的着装方式也正符合这一理念——中心部位不受寒，给予下肢冷刺激。
“其实寒冷能刺激生长激素释放。”钱尚统进一步解释道，孩子生长的关键在于生长激素，而让孩子有些寒冷的感觉便能促使人体自身释放生长激素，“当然我提倡的是给予孩子适当的冷刺激，而不是一直让孩子在寒冷的环境里，比如现在秋天不要加衣服太快，如果孩子在换季过程中没有感受到冷，缺乏冷刺激，无论对生长还是呼吸道都不是很好。”而令人担心的现状是，国人的养育观念普遍给孩子穿得太多。
此外，据钱尚统介绍，饥饿感有助于生长，因而钱尚统总是叮嘱患儿的家长在保证孩子三餐营养摄入均衡的基础上，没有必要时不时给孩子吃零食和点心，从中医角度讲，人的脾胃有一个工作和休息交替的过程，如果没有饥饿感，脾胃得不到休息，不但孩子长不高，甚至会导致肥胖。
让孩子21点前睡着
睡觉也是助长因素中至关重要的一环。钱尚统非常珍惜晚上9时到次日凌晨6时的睡眠时间，他强调，为了保证青少年的身高，晚9点必须熄灯睡觉。学龄前儿童要睡足10小时，青少年要睡足9-10小时。
为什么在这个时间段睡眠更有利于生长？这是因为人体80%的生长激素是在晚上分泌的。从生长激素分泌曲线图可明显看到，晚上10点之后是生长激素分泌达到一天中的最高峰，可以达到白天的5-7倍，而凌晨5时至6时又会出现一个生长激素分泌小高峰。“睡眠是由浅入深，若是晚上9点入睡，浅睡眠1小时，到晚上10点已进入深睡眠，也就能和生长激素分泌高峰同步。”钱尚统说道。
