<\/div>\n<\/div>\n<\/div>\nIn many families, a child\u2019s height is solely related to genetics. \u201cHeight runs in the family\u201d is a sentence used countless times. Many believe if the parents are short, the child will also grow up to be short and if they\u2019re tall, the child will likely grow up to be the same. However, for many years, the drastic change in height growth in some countries surprised researchers. Among the most striking examples are China and South Korea, where children and teenagers gained significant height compared to previous generations. Children whose parents were shorter grew up to be taller. Explaining this, parenting and child development coach Hitesh M offered an important lesson for Indian parents. Giving the examples of veteran Bollywood actor Aamir Khan\u2019s son and cricket legend Sachin Tendulkar\u2019s son, the expert noted that height is not determined by genetics alone. If height were determined by genetics alone, their kids should have been shorter.<\/p>\n 23 Jun 2026 | 13:57<\/p>\n Chinese and South Korean children grew taller in one generation: What are the learnings for parents to support height growth in kids<\/p>\n<\/div>\n<\/div>\n Parenting and child development coach Hitmesh M mentioned the study that analysed height and body mass index trends among school-aged children and adolescents across 200 countries and territories. The 2020 study published in The Lancet examined data from more than 65 million participants collected between 1985 and 2019. The findings revealed substantial height gains among children in several East Asian countries, particularly China and South Korea.The Lancet study showed how dramatically children’s height can change across generations when nutrition, health, and living conditions improve.<\/p>\n Parenting and child development coach Hitesh M says Indian parents can learn from China and South Korea by focusing on four everyday factors to support healthy growth. These factors are: <\/p>\n When parents consider their child\u2019s height, they often focus on supplements, special foods, or powders. However, studies note that height growth starts with something much simpler: Nutrition. Hitesh highlights four nutrients that deserve special attention: protein, iron, zinc, and calcium. \u201cWhen you provide your kids with protein, iron, zinc, and calcium, that nutrition really helps your children to grow taller,\u201d notes Hitesh. Some sources of these nutrients are: <\/span>Protein: egg, dairy products , chicken, fish, nuts and seeds.Iron: green leafy vegetables, lentils, beans, meatZinc: Dairy products, seeds, meat, whole grainsCalcium: milk, curd, paneer, ragi, sesame seeds<\/p>\n Modern childhood has become increasingly indoor-oriented. This matters because movement itself supports healthy development. \u201cMovement is important for children\u2019s height,\u201d notes the expert.Physical activity helps strengthen bones and muscles while supporting overall health. Active children are often more likely to maintain healthy growth patterns than children who spend most of their time sitting.<\/p>\n Outdoor play has another important benefit: sunlight. Sunlight remains one of the most natural sources of vitamin D, a nutrient that helps the body absorb calcium effectively. \u201cSunlight is the most natural source of vitamin D for our children. Unfortunately, Indian children are not playing in the sun anymore, which means that a lot of Indian children are deficient in vitamin D,\u201d notes Hitesh M. <\/p>\n Many parents pay close attention to what their child eats but not necessarily to how much they sleep. Yet sleep is one of the most important periods for growth. \u201cGrowth hormone is secreted when the child is asleep,\u201d says child development expert Hitesh M. Thus healthy growth requires healthy sleep. The body does a lot of its repair and development work while children are sleeping. <\/p>\n The story of height gains in countries like China and South Korea is not really about becoming taller. It is about what happens when children grow up with better nutrition, healthier lifestyles, and improved living conditions. For Indian parents, the lesson is simple: while genes may set the blueprint, daily habits help determine how much of that blueprint becomes reality. <\/p>\n Chinese and South Korean children grew taller in one generation: What are the learnings for parents to support height growth in kids<\/p>\n<\/div>\n<\/div>\n However, while height often becomes a topic of discussion among parents, experts believe it is important to view it in the right perspective. A child\u2019s height is only one aspect of their overall growth and development, not a measure of their health, intelligence, abilities, or future success. The focus should not be on chasing a particular number on the height chart or comparing children with their peers. Instead, parents can focus on creating an environment where children have the right support to grow naturally.<\/div>\nWhat\u2019s the one thing you did that worked for your child\u2019s height growth?<\/h2>\n<\/div>\n<\/div>\n
