The flexitarian diet has gained popularity in recent years as a flexible and sustainable approach to eating. It emphasizes plant-based foods while still allowing for occasional consumption of meat and other animal products. While this diet may be suitable for adults, many parents wonder if it is appropriate for their children and teenagers. In this article, we will explore the suitability of the flexitarian diet for kids and teens, considering their nutritional needs, growth requirements, and potential benefits and drawbacks. By examining the available research and expert opinions, we aim to provide valuable insights for parents who are considering adopting a flexitarian lifestyle for their families.

The Nutritional Needs of Kids and Teens

Before delving into the suitability of the flexitarian diet for children and teenagers, it is important to understand their unique nutritional needs. During these crucial stages of growth and development, young individuals require a well-balanced diet that provides them with all the necessary nutrients.

1. Macronutrients:

  • Protein: Protein is essential for growth, muscle development, and tissue repair. While plant-based sources like legumes, tofu, and tempeh can provide adequate protein, it is important to ensure that children and teenagers consume a variety of these foods to meet their protein needs.
  • Carbohydrates: Carbohydrates are the primary source of energy for the body. Whole grains, fruits, and vegetables should be included in the diet to provide a steady supply of carbohydrates.
  • Fats: Healthy fats are crucial for brain development and hormone production. Nuts, seeds, avocados, and olive oil are excellent sources of healthy fats.

2. Micronutrients:

  • Calcium: Calcium is essential for building strong bones and teeth. While dairy products are a common source of calcium, plant-based alternatives like fortified soy milk, almond milk, and leafy greens can also provide this important mineral.
  • Iron: Iron is necessary for the production of red blood cells and oxygen transport. Plant-based sources of iron include legumes, tofu, spinach, and fortified cereals.
  • Vitamin B12: Vitamin B12 is primarily found in animal products, and its deficiency can lead to anemia and neurological problems. If following a flexitarian diet, it is important to ensure adequate intake of vitamin B12 through fortified foods or supplements.

The Flexitarian Diet for Kids and Teens

Now that we have a better understanding of the nutritional needs of children and teenagers, let’s explore the suitability of the flexitarian diet for this age group.

1. Adequate Nutrient Intake

One concern parents may have is whether a flexitarian diet can provide all the necessary nutrients for their growing children. While a well-planned flexitarian diet can meet these requirements, it is important to pay attention to the variety and quality of foods consumed.

Research has shown that vegetarian and vegan diets can be nutritionally adequate for children and teenagers when properly planned. A study published in the Journal of the American Dietetic Association found that vegetarian diets can provide all the necessary nutrients for growth and development when they include a variety of plant-based foods and appropriate supplementation.

However, it is important to note that a poorly planned flexitarian diet that relies heavily on processed foods and lacks variety may not meet the nutritional needs of children and teenagers. Parents should ensure that their child’s diet includes a wide range of fruits, vegetables, whole grains, legumes, nuts, and seeds to provide a diverse array of nutrients.

2. Protein and Iron Sources

Protein and iron are two nutrients that are often a concern when adopting a flexitarian diet. While meat is a rich source of both, there are plenty of plant-based alternatives that can provide adequate amounts of these nutrients.

Plant-based protein sources like legumes, tofu, tempeh, and seitan can be included in a flexitarian diet to meet protein requirements. Additionally, incorporating a variety of whole grains, nuts, and seeds can further contribute to protein intake.

Iron can be obtained from plant-based sources such as legumes, dark leafy greens, fortified cereals, and dried fruits. Consuming these foods alongside vitamin C-rich foods like citrus fruits or bell peppers can enhance iron absorption.

3. Calcium and Vitamin D

Calcium and vitamin D are essential for bone health, and their adequate intake is particularly important during childhood and adolescence. While dairy products are a common source of these nutrients, flexitarians can obtain them from plant-based alternatives.

Fortified plant-based milks, such as soy milk and almond milk, can provide calcium and vitamin D. Additionally, leafy greens like kale and broccoli are good sources of calcium. Exposure to sunlight is also important for vitamin D synthesis, so spending time outdoors can help ensure adequate levels of this vitamin.

Potential Benefits and Drawbacks

Now that we have explored the nutritional aspects of the flexitarian diet for kids and teens, let’s consider the potential benefits and drawbacks of adopting this eating pattern.

1. Benefits

1. Healthier Food Choices: The flexitarian diet encourages the consumption of whole, plant-based foods, which are generally associated with numerous health benefits. By focusing on fruits, vegetables, whole grains, and legumes, children and teenagers can develop healthy eating habits that may reduce the risk of chronic diseases later in life.

2. Environmental Sustainability: The flexitarian diet promotes a reduction in meat consumption, which can have positive environmental impacts. By choosing plant-based options more often, children and teenagers can contribute to a more sustainable food system and help mitigate climate change.

2. Drawbacks

1. Nutritional Imbalance: While a well-planned flexitarian diet can provide all the necessary nutrients, there is a risk of nutritional imbalance if the diet is not properly planned. Parents must ensure that their child’s diet includes a variety of plant-based foods to meet their nutritional needs.

2. Social Challenges: Following a flexitarian diet may present social challenges for children and teenagers, especially in settings where meat consumption is the norm. It is important for parents to support their child’s dietary choices and provide guidance on how to navigate social situations.


The flexitarian diet can be a suitable and healthy eating pattern for children and teenagers when properly planned. By ensuring an adequate intake of macronutrients, micronutrients, and essential vitamins and minerals, parents can support their child’s growth and development while promoting a more sustainable food system.

However, it is crucial to emphasize the importance of a well-balanced and varied diet that includes a wide range of plant-based foods. Parents should consult with healthcare professionals or registered dietitians to ensure that their child’s nutritional needs are being met.

Ultimately, the decision to adopt a flexitarian diet for kids and teens should be based on individual circumstances, preferences, and nutritional considerations. By providing the necessary support and guidance, parents can help their children make informed choices about their dietary habits and promote a healthy and sustainable lifestyle.
