There is a common misconception that a vegetarian or vegan diet stunts growth, particularly in children and teenagers. However, studies have shown that a well-planned and balanced plant-based diet can provide all the necessary nutrients for adequate growth and development. While some research suggests that vegan children may be shorter on average than their non-vegan peers, this could be due to a variety of factors, including inadequate nutrition, a lack of supplementation, and the inclusion of heavily processed meat-free foods. It is important to consult a healthcare professional or a registered dietitian to ensure that a vegetarian or vegan diet meets all the necessary nutritional requirements for proper growth and development.

A well-planned vegetarian diet can be nutritionally adequate
A well-planned, balanced vegetarian or vegan diet can be nutritionally adequate. It is important to consume a variety of foods and the right amount of foods to meet calorie needs. Following food group recommendations for one's age, sex, and activity level can ensure the right amount and variety of foods are consumed for nutrient adequacy.
Vegetarian diets can meet all nutrient recommendations. However, nutrients that vegetarians may need to focus on include protein, iron, calcium, zinc, and vitamin B12. For example, vegetarians can get enough protein by eating a variety of plant-based sources, such as beans, tofu, and nuts. Similarly, calcium can be obtained from dark leafy greens, calcium-fortified orange juice, and dairy products, if consumed.
Vegan diets are a type of vegetarian diet that only includes plant-based foods. With good planning, those following a vegan diet can cover all their nutrient bases. However, there are some extra considerations. For example, vegans may need to supplement their diets with specific nutrients like B vitamins, calcium, and vitamin D. This is because studies have shown that vegan children are more likely to be deficient in these vitamins and have lower bone mineral density, which could impact their growth.
It is important to note that some studies suggesting that vegan diets stunt growth were conducted on children who were not receiving adequate nutrition. These children were following a raw vegan diet, which lacked calcium, zinc, and vitamin D. Therefore, it is essential to consult a healthcare professional or a registered dietitian to ensure a vegetarian or vegan diet is well-planned and nutritionally adequate.

Vegan children are shorter on average
A vegan diet for children has been a topic of debate, with some studies suggesting that vegan children are shorter on average. One study, in particular, found that children aged five to ten who follow plant-based diets are on average 1.2 inches or three centimetres shorter than those who consume meat. They also had weaker bones and were more likely to be deficient in vitamin B12.
However, it is important to note that a well-planned and balanced vegan diet can provide all the necessary nutrients for adequate growth and development. Studies of UK vegetarian and vegan children have shown that their growth and development fall within the normal range. The key is to ensure a varied diet that meets the calorie needs and nutrient requirements for a child's age, sex, and activity level.
The concern about stunted growth in vegan children may stem from inadequate nutrition or a lack of supplementation. For example, some studies from the 1980s and 1990s observed slower growth in children following a raw vegan or macrobiotic diet, which lacked calcium, zinc, and vitamin D. Additionally, infants on homemade formulas may not receive adequate nutrition, leading to slower growth.
To ensure healthy growth and development, it is crucial for vegan children to have proper meal planning and supplementation. Vitamin B12, for instance, can be obtained through supplements or fortified foods. By addressing these nutritional considerations, vegan children can grow and develop healthily, and any height differences compared to non-vegan children may be minimal.

Vegan diets can cause vitamin deficiencies
While a vegan diet has been associated with various health benefits, it may not contain all the necessary nutrients and could lead to nutritional deficiencies. A comprehensive review published in the medical journal Progress in Cardiovascular Diseases highlights the negative health impacts of a strict vegan diet, noting the absence of randomized controlled trial data showing its long-term safety or effectiveness.
One of the main concerns with a vegan diet is the risk of vitamin deficiencies. Here are some key vitamins that vegans may need to supplement:
Vitamin B12
Vitamin B12 is commonly found in animal-based foods, and vegans may need to take a supplement to ensure adequate intake. Vitamin B12 is essential for maintaining energy levels and overall health.
Vitamin D
Vitamin D is crucial for maintaining bone health and muscle function. Deficiency in vitamin D is linked to an increased risk of osteoporosis and fractures, especially in older adults. Vegans can obtain vitamin D2 from supplements, mushrooms, and fortified foods. However, vitamin D3, the more effective form of the vitamin, is typically found in animal-sourced foods.
Iron
Iron is essential for helping blood cells carry oxygen and supporting brain health. While plant-based products contain iron, it is in the form of nonheme iron, which is harder for the body to absorb. As a result, vegans may require up to twice the recommended amount of iron to meet their daily needs.
Iodine
Iodine is another nutrient that vegans may need to supplement. Iodine is commonly found in meats, fish, and eggs, and a deficiency can impact overall health.
Omega-3 Fatty Acids
Omega-3 fatty acids, specifically DHA, are important for normal brain development and function. A deficiency in DHA can adversely affect mental health and brain function, especially in children.
While a vegan diet can be nutritionally adequate with careful planning, it is important to be aware of these potential vitamin deficiencies and work with a healthcare provider to ensure a well-rounded and varied diet or supplement regimen.

Weight-lifting and gymnastics can stunt growth
It is a common misconception that weightlifting and gymnastics can stunt growth, particularly in children and adolescents. However, this claim is not supported by scientific evidence. On the contrary, research suggests that strength training can positively contribute to physical maturity and overall well-being when conducted correctly and under proper supervision.
The belief that these activities can hinder growth is primarily based on the concern that putting stress on growth plates, or epiphyseal plates, could negatively affect height. Growth plates are areas of cartilage located near the ends of long bones, which are sensitive during childhood and adolescence. However, studies have shown that proper weightlifting does not cause harm to these areas.
For example, a 2020 clinical report from the American Academy of Pediatrics found that properly designed resistance training programs had no negative impact on linear growth, growth plate health, or the cardiovascular system of children and adolescents. Additionally, a research review published in Frontiers in Physiology in 2016 concluded that resistance training can provide benefits for long-term health and athletic performance through neuromuscular adaptation.
It is important to note that, as with any exercise, there is a risk of injury if weightlifting or gymnastics are performed incorrectly. Therefore, it is crucial that young athletes engage in these activities under the guidance of qualified professionals who can ensure proper form and technique. By providing effective supervision and guidance, the potential for injury can be minimized.
In conclusion, while there may be individual variations in growth patterns among those who participate in weightlifting and gymnastics, the available evidence suggests that these activities do not inherently stunt growth. On the contrary, when performed correctly and safely, they can contribute to healthy growth and development, improving bone density, muscle strength, and overall health.
