Spring temperatures gradually warm up, which is a golden time for children in their growth and development stages to grow tall. "Some studies have shown that children's growth is seasonal, and they tend to grow faster in spring." Liu Ailing, a researcher at the Institute of Nutrition and Health of the China Center for Disease Control and Prevention, said that the temperature rises in spring, and children's outdoor activities increase. Adequate light can promote the synthesis of vitamin D and calcium absorption in the body, providing sufficient raw materials for the growth of children's bones. In addition, the vigorous metabolism of the human body and the increased secretion of growth hormone in spring are also conducive to the growth of children. How to make good use of children's spring growth period? Reasonable nutrition is the "soil" necessary for children's growth. Liu Ailing introduced that according to the "Dietary Guidelines for Chinese Residents (2022)", daily meals should include cereals and potatoes, vegetables and fruits, livestock, poultry, fish, eggs, milk, and soybeans. Through reasonable collocation, it can basically meet the needs of physical growth. Parents should pay special attention to the intake of high-quality protein, calcium, iron, zinc, and other elements, which are closely related to the growth of children's bones. Daily intake of 300 to 500 milliliters of liquid milk or equivalent amounts of dairy products is essential. Red meat and animal liver are the main sources of iron and zinc, and can be eaten 1-2 times a week. "We also need to maintain moderate exercise," Liu Ailing said. Exercise to overcome self gravity and weight bearing exercises with longitudinal movements can stimulate bone growth. It is generally recommended that children engage in outdoor activities for at least 2 hours per day, with physical activity of moderate or higher intensity not less than 1 hour. They should engage in three days of exercise a week to strengthen their bones, such as running, rope skipping, basketball, volleyball, and other sports that have significant ground reactions, which are very important for promoting growth. "The height of a child is the result of a combination of genetic and environmental factors, and development occurs first and then." Liu Ailing said that parents should pay attention to the height changes of their child, pay attention to balanced nutrition, moderate exercise, and adequate sleep. (Liao Xinshe)
