Understanding the Nutritional Needs of Growing Teens

Understanding the Nutritional Needs of Growing Teens

How to Ensure They Get the Right Fuel for Growth and Energy


You’ve got a teen, and suddenly, the grocery bill looks like you’re feeding a small army.  And what do they actually eat? 

A bag of chips, a soda, and maybe — just maybe — a slice of pizza that’s somehow “healthier” than the fast food they wanted.  All in the middle of the night while you are sleeping.

Let’s hope not!

Navigating a teen’s nutritional needs can feel like trying to fuel a race car with a leaky gas tank:  they’re always hungry, picky, and, let’s face it, their idea of a balanced meal is anything that’s quick and doesn’t include vegetables. 

But with a little know-how, you can help your teen thrive with the right fuel, so let’s break it down before their next “snack” turns into an entire pizza.

As teens transition from childhood to adulthood, their bodies undergo rapid changes.  From growth spurts to hormonal shifts, the physical and emotional demands placed on adolescents can be overwhelming.  One of the most critical aspects of supporting these changes is ensuring that your teen gets the right nutrition.   

Unfortunately, many parents find themselves struggling to meet the nutritional needs of their teens, especially with busy schedules, picky eating habits, and the allure of fast food.

Understanding the nutritional needs of growing teens is crucial not just for physical growth but also for emotional well-being, mental health, and overall performance in school and extracurricular activities.  So, how can you, as a parent, ensure your teen is getting the right fuel for these transformative years? Let’s dive into the problem and explore practical, research-backed solutions to help your teen thrive.

Nutritional Gaps and Poor Eating Habits in Teens

Adolescence is a time of significant physical, emotional, and cognitive development, all of which require proper nutrition.   However, many teens struggle to meet their nutritional needs due to various challenges:

Increased Caloric Needs During Growth Spurts:  As teens grow taller and develop more muscle mass, their bodies require more calories to sustain this growth.   Many teens, especially active ones, might find that their hunger levels increase.   However, many turn to unhealthy options such as sugary snacks, fast food, or empty-calorie convenience foods that don’t provide the essential nutrients their bodies need for optimal growth.

Research Insight:  Studies show that adolescents need more calories than children, but the quality of those calories matters.  The Journal of the American Dietetic Association emphasizes that during puberty, teens require extra calories primarily from nutrient-dense foods that contain the necessary vitamins, minerals, protein, and healthy fats.

Poor Eating Habits and Picky Eating:  Teenagers are notorious for being picky eaters.  They might be more interested in snacking throughout the day or indulging in sugary treats rather than sitting down for balanced meals.  This can lead to nutritional imbalances, such as insufficient protein, vitamins, or minerals, which are crucial during growth periods.

Research Insight:  A 2020 study published in Nutrients found that the eating habits of adolescents, including skipping meals and consuming fast food, are associated with poor nutrient intake, which can contribute to deficiencies in essential vitamins like A, D, and C, as well as calcium, magnesium, and iron.

Lack of Time and Convenience:  With packed schedules of school, extracurricular activities, and social events, many teens opt for fast, convenient food options that don’t necessarily meet their nutritional needs.  Whether it’s grabbing something from the vending machine or picking up fast food on the way home from practice, these meals can be low in essential nutrients and high in unhealthy fats, sodium, and sugars.

Research Insight:  According to a 2019 American Journal of Public Health study, adolescents are particularly vulnerable to making poor food choices when convenience trumps nutrition.  When teens eat out or rely on processed foods, they tend to miss out on whole grains, fruits, vegetables, and other nutrient-dense foods.

Body Image Concerns and Dieting:  The teen years are also fraught with concerns about body image.  This can sometimes lead to restrictive eating behaviors or fad dieting.  While some teens may skip meals or adopt unhealthy dieting trends, others may overeat as a way to cope with emotional stress.  Both behaviors can hinder proper nutrition and stunt growth, affecting both physical health and mental well-being.

Research Insight:  According to the National Eating Disorders Association, adolescence is a key period for the onset of eating disorders.  Unhealthy eating patterns, such as skipping meals or extreme calorie restriction, can have lasting effects on physical health, leading to deficiencies that impair growth, bone development, and cognitive function.

How to Meet the Nutritional Needs of Growing Teens

While it’s clear that there are challenges in ensuring teens get the right nutrition, the good news is that there are effective strategies that can make a significant difference.  Here are some evidence-based solutions to support your teen’s growth and health through proper nutrition.

Prioritize Balanced, Nutrient-Dense Meals

The Problem:  Teens often gravitate toward unhealthy, processed foods that are high in sugar, sodium, and empty calories, neglecting the foods that are crucial for growth and development.

The Solution:  Encourage balanced meals that include a variety of nutrient-dense foods.  A good rule of thumb is to aim for meals that are rich in protein, healthy fats, fiber, and vitamins and minerals.   

Here’s what to focus on:

Protein:  Protein is essential for muscle growth and repair.  Encourage lean meats, fish, eggs, beans, and legumes.

Healthy fats:  Fats support brain function and hormone production.  Include avocados, nuts, seeds, and olive oil.

Fiber:  Whole grains, fruits, and vegetables provide the fiber necessary for digestion and overall health.

Vitamins and minerals:  Make sure your teen gets enough calcium (for bone development), iron (for energy), and vitamins A, D, and C (for immune function and skin health).

Example Meal:  A grilled chicken salad (or vegan alternatives) with mixed greens, avocado, quinoa, and a yogurt-based dressing is a great example of a balanced, nutrient-dense meal.

Encourage Regular, Balanced Snacks

The Problem:  Teens often skip meals, relying on unhealthy snacks when they feel hungry.   These snacks often lack the nutrients needed to sustain them throughout the day.

The Solution:  Provide your teen with healthy snack options that are rich in protein, fiber, and healthy fats.   

Encourage snacks like:

— Hummus and carrot sticks

— Greek yogurt with berries and almonds

— Apple slices with peanut butter

— A smoothie with spinach, protein powder, and fruit

Research Insight:  A study published in Appetite found that when teens consume nutrient-dense snacks, they’re less likely to experience dips in energy and mood.   Snacks can help stabilize blood sugar levels and provide the fuel necessary for mental clarity and physical activity.

Involve Your Teen in Meal Planning and Cooking

The Problem:  Teens often feel disconnected from family meals, especially if they don’t have a say in what’s for dinner.  When kids are involved in meal planning, they’re more likely to enjoy and eat healthier meals.

The Solution:  Make meal planning and cooking a family affair.  Get your teen involved in selecting healthy recipes, going grocery shopping, and preparing meals together.  This not only teaches them valuable cooking skills but also gives them a sense of ownership over their food choices.

Tip:  Encourage your teen to explore new recipes or cuisines, making the experience enjoyable and educational.  Whether they’re making homemade pizzas with healthy toppings or preparing a salad bar, giving them agency over what they eat fosters independence and a positive relationship with food.

Encourage Healthy Hydration Habits

The Problem:  Teens are more likely to reach for sugary sodas, energy drinks, or coffee, which can lead to dehydration and unnecessary sugar intake.

The Solution:  Encourage your teen to drink water consistently throughout the day.   Aim to have them drink water first thing in the morning and throughout the day, especially before and after physical activities.  You can also offer herbal teas, flavored water, or smoothies as healthy alternatives to sugary drinks.

Tip:  Consider getting a reusable water bottle that your teen can keep with them, making it easier to stay hydrated on the go.

Address Body Image and Support Healthy Relationships with Food

The Problem:  The teen years are often marked by body image concerns, which can lead to disordered eating behaviors or unhealthy dieting.

The Solution:  Foster a healthy relationship with food by emphasizing balance and nourishment over restriction.  Help your teen understand that food is fuel for their bodies and should be seen as something to celebrate, not fear.  Encourage positive conversations about body image, focusing on the importance of strength, health, and well-being rather than appearance.

Tip:  Be mindful of your own language around food and body image.  Modeling healthy behaviors and attitudes about food can have a positive influence on your teen’s relationship with their body and food choices.

Helping Teens Thrive Through Proper Nutrition

Ensuring that your teen gets the right nutrition is key to supporting their physical, cognitive, and emotional development.  By prioritizing balanced meals, encouraging healthy snacks, involving them in meal preparation, and addressing body image concerns, you can help your teen meet their nutritional needs and thrive during these transformative years.

With a little education and a lot of patience, you can help your teen develop healthy habits that will set them up for success, not just during adolescence but for the rest of their lives.  By understanding the unique nutritional needs of growing teens and implementing practical strategies, you’re setting the foundation for a healthier, happier future.
