Because the growth rate is accelerated in May-10, more nutrients must be consumed, so it is necessary to grasp the best time for human growth. Nutritionists believe that all kinds of nutrition should be supplemented in time to promote the needs of human growth and development and enhance disease resistance.
Scientists have found that in addition to good sleep and proper exercise, the human body needs as many as 365,438+0 nutrients at the same time to grow taller, and all three are indispensable. It is impossible to grow taller by relying solely on one or several nutrients.
Extended data:
For many years, China's parents have always wanted their children to grow taller. Girls are tall and beautiful, and boys are tall and handsome. "Height" has become a pursuit in the bones of Chinese people. A recently released global research data also shows that the height of China people has greatly improved compared with that of a hundred years ago.
After comparing and analyzing the height data of young people in 19 14 and 20 14 years, the Imperial College London Research Group in London found that Dutch men and Latvian women had the highest average height. During the period of 100, the population height of some countries increased greatly.
Among them, the average height of Korean women in 20 14 years was 1.623 m, which was 20.2 cm higher than that in the past hundred years. Compared with South Korea, the average height of young men and women in Chinese mainland has increased steadily, increasing by 1 1 cm and 10 cm respectively, reaching 1.7 18 m and1.597m. ..
The growth rate of height in the United States, Britain and Japan is relatively slow.
Japanese men and women are 1.708m and 1.583m respectively.
China's Bulletin on National Physical Fitness Monitoring also shows that the average height of people in China has increased steadily in recent years. Jiang Chongmin, director of the Youth Sports Development and Research Center of the Sports Science Research Institute of the State Sports General Administration, said that since 2000, the State Sports General Administration has conducted national physical fitness monitoring every five years. The survey shows that the height of people of all ages in China has increased to varying degrees.
Taking the age of 20-24 as an example, the height of men increased from 1.694 m to 1.7 19 m, and that of women increased from 1.586 m to 1.598 m, especially for children. According to the data of 20 16, the height of children aged 5-5.5 has increased by 8.0 cm and 8.2 cm respectively in 40 years. Jiang Chongmin pointed out.
At present, the national height of China is basically the same as that of Japan, although the growth rate is slightly behind that of some European countries, it is within the normal growth range.
Acquired factors should not be underestimated.
"This height growth rate reflects the efforts of China people the day after tomorrow." Jiang Chongmin mentioned that since the reform and opening up, the economy has grown rapidly, the food supply is sufficient, the basic nutrition has been guaranteed, and the medical level has been continuously improved. Especially since the promotion of national fitness, we have obtained moderate physical labor and exercise, and the growth and development of teenagers are more adequate.
Although the height growth of China people is gratifying, there is still a gap compared with South Korea, which is also an Asian population. Experts believe that this may be related to the problems in nutrition balance and physical activity in China.
Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, believes that in recent years, China people have gained more weight than their height. This is mainly because people's nutritional intake is not balanced enough, fat is too much, and vitamins and calcium are seriously insufficient.
After the infiltration of western diet, we did not have the good habit of absorbing less salt and more milk, but developed the habit of eating high-calorie foods such as hamburgers and fast food. In addition, left-behind children in rural areas are malnourished, have heavy physical labor and are "crushed" in height.
Zhang Hongmei, chief physician of Endocrinology Department of central hospital of wuhan, pointed out that the insufficient intake of protein and calcium in rural children directly affects the normal development of their muscles and bones, and ultimately limits their height.
20 15 Report on Nutrition and Chronic Diseases of China Residents shows that the incidence of growth retardation is as high as 1 1.3% in ordinary rural areas and 19.0% in poverty-stricken areas.
After World War II, the average height of Japanese people has soared to more than 10 cm, which also proves the influence of nutrition and exercise on height to some extent. 1954, the Japanese parliament passed the School Feeding Law, which clearly stipulated that students' nutritious lunches should be promoted in primary and secondary schools with compulsory education throughout the country. In the 1960s, the campaign "A glass of milk makes a nation strong" was launched, and "milk between classes" was widely promoted from kindergarten to junior high school.
Paying attention to young people's physical exercise is also an important practice adopted by Japan after World War II. 1964 After the Tokyo Olympic Games, Japan promulgated the "Sports Revitalization Law", which stipulated the "National Physical Exercise Day", school physical education hours and compulsory sports events in legal form.
Height not only affects life choices such as job hunting, making friends and psychological development, but also concerns the image and status of a country. The average height has brought many troubles to Vietnamese. For this reason, Vietnam has put forward the goal of increasing the average height by about 4 cm by 2030, and expressed its willingness to spend 300 million US dollars to achieve the goal.
Seize the golden period of "growing taller"
"Growing up" is no small matter. Infants and adolescents are the "golden period" of growth. Zhang Hongmei believes that efforts should be made in nutrition, sleep and exercise.
Balanced nutrition. The growth and development of bones are inseparable from minerals such as protein, calcium, phosphorus and zinc. A glass of milk and an egg every day is the secret of increasing height. Besides ensuring the intake of high-quality protein, we should also pay attention to controlling the intake of junk food such as fast food.
Teenagers with moderate exercise should insist on at least 1 hour of outdoor sports every day, such as bungee jumping, shuttlecock kicking, high jump and other systemic sports such as basketball and volleyball. Overweight activities such as water lifting and farm work, as well as weight-bearing training such as weightlifting and shot put, should be controlled in intensity.
Get enough sleep. Medical research shows that 80% of growth hormone is produced during sleep. At night, make sure that your child falls asleep before 10, ensure at least 8 hours of adequate sleep, and create a quiet sleeping environment.
Correct posture. Some children don't pay much attention to the posture of standing, sitting, walking, reading and writing, which leads to the deformation of the spine and affects their height. Overweight schoolbags can also affect bone growth. While correcting posture, parents are advised to reduce the weight of their children's schoolbags.
Get more sunshine. Regular sun exposure can promote the synthesis of vitamin D, which is beneficial to the accumulation of calcium in bones and promote growth. Teenagers should receive 1 ~ 2 hours of sunshine every day, and take more outdoor activities.
Regular physical examination. Parents should regularly measure their children's height and monitor their growth rate. If the height gap with children of the same age is too large, parents should take their children to the pediatric endocrinology department for consultation and examination as soon as possible.
Finally, Jiang Chongmin reminded that height does not mean everything. Don't blindly pursue height increase, be superstitious about drugs or surgery, and don't feel inferior because you are too tall and too short. "Growing up" is not only "growing up", but also the strength, balance and endurance of teenagers.
