Nutritional Requirements for Adolescents
During adolescence, the body undergoes significant changes, and proper nutrition is crucial to support this phase of growth and development. Adolescents have distinct nutritional requirements that differ from those of children and adults.
Energy
Adolescents experience a substantial increase in energy requirements due to their rapid growth and development. Energy needs are influenced by factors such as age, gender, activity level, and individual growth rate. On average, adolescent boys require around 2,200 to 3,200 calories per day, while girls typically need 1,800 to 2,400 calories daily.
It’s essential for adolescents to obtain their energy from nutrient-dense sources to support overall health. Encouraging them to consume a variety of foods rich in complex carbohydrates, healthy fats, and lean proteins is vital. Whole grains, fruits, vegetables, nuts, and lean meats should be staples in their diets to provide sustained energy and support growth.
Protein
Protein is a crucial nutrient for adolescents as it plays a fundamental role in building and repairing tissues, including muscles. During the adolescent growth spurt, protein requirements increase. On average, adolescents need approximately 0.85 to 0.95 grams of protein per pound of body weight.
Good sources of protein include lean meats, poultry, fish, eggs, dairy products, legumes, and tofu. Encourage adolescents to incorporate these protein-rich foods into their meals to support muscle development and overall growth.
Calcium
Calcium is essential for building strong bones and teeth, and it plays a critical role in the development of peak bone mass during adolescence. It is crucial to ensure that adolescents get enough calcium to reduce the risk of osteoporosis later in life.
On average, adolescents require 1,300 milligrams of calcium daily. Dairy products like milk, yogurt, and cheese are excellent sources of calcium. However, for those who are lactose intolerant or prefer non-dairy options, fortified plant-based milk alternatives, fortified orange juice, and leafy green vegetables like kale and broccoli can provide calcium.
Iron
Iron is vital for transporting oxygen throughout the body, and adolescents need an increased intake to support their growing muscles and tissues. Adolescent girls, in particular, are at higher risk of iron deficiency due to menstrual losses.
The recommended daily intake of iron for adolescent boys is around 11 milligrams, while girls need approximately 15 milligrams. Lean meats, poultry, fish, beans, lentils, fortified cereals, and spinach are excellent sources of iron. Pairing iron-rich foods with vitamin C-rich foods, like citrus fruits, can enhance iron absorption.
Folate
Folate is essential for cell division and tissue growth. It plays a crucial role in the development of the neural tube during early pregnancy, making it important for adolescent girls who may become pregnant.
The recommended daily intake of folate for adolescents is 400 micrograms. Good sources of folate include leafy green vegetables, fortified cereals, beans, lentils, and citrus fruits. Encourage adolescents, especially girls, to include these foods in their diets to ensure adequate folate intake.
Zinc
Zinc has pivotal roles in digestion, hormonal and gut signaling, neurotransmitter synthesis,
And enzymatic processes in the body that regulate appetite and mood. Deficiencies in this imperative micronutrient may arise from lack of animal protein in the diet. Sources of Zinc include oysters and other seafood, like fish, as well as meat, chickpeas, lentils and dairy products. The recommended daily intake for zinc is about 11 mg for adolescent boys and 9 mg for girls. A growing body of research suggests Zinc deficiency may play a role in eating disorder pathology, underscoring its roles in taste, mood and digestion.
Fiber
Fiber is essential for digestive health and can help prevent constipation, a common issue among adolescents. It also aids in maintaining a healthy weight and reducing the risk of chronic diseases.
Adolescents should aim for around 25 to 38 grams of fiber daily, depending on their age and gender. Whole grains, fruits, vegetables, legumes, and nuts are excellent sources of dietary fiber. Encourage them to choose whole, unprocessed foods to meet their fiber needs.
Hydration
Proper hydration is often overlooked but is critical for overall health and well-being. Adolescents should aim to drink plenty of filtered water throughout the day to stay adequately hydrated, especially if they are physically active.
It’s essential to emphasize water as the primary source of hydration and limit the consumption of sugary beverages like soda and energy drinks. Encourage adolescents to carry a glass reusable water bottle and drink water regularly.
The Adolescent Growth Spurt
One of the defining characteristics of adolescence is the significant growth spurt that occurs during this period. Typically beginning around ages 10 to 11 in girls and 12 to 13 in boys, this rapid growth phase continues until approximately ages 15 to 17 in girls and 17 to 19 in boys.
During the growth spurt, adolescents experience a dramatic increase in height, weight, and muscle mass. This period of accelerated growth places additional demands on their nutritional requirements, emphasizing the importance of a balanced and nutrient-rich diet to support healthy development.

Eating Disorders in Adolescence
Eating disorders are serious illnesses that evolve from the dynamic interplay of genetics, psycho-social and neurobiological factors such as alterations in regulating signals between the brain and body. Addressing eating disorders from this multifaceted perspective addresses underlying root causes and contributing factors to these serious illnesses by taking a personalized approach supporting sustained recovery
Malnutrition, chronic emotional stress, body image concerns and harmful dieting tactics can further compound these factors. For instance, restricting certain foods can lead to nutritional deficiencies which can further drive biological alterations in the body and mind.
Insufficient levels of fatty acids have been found in those with eating disorders. This is significant, as 60% of the brain is made up of fat. When the brain is starved of fat, function declines which can perpetuate pathology and symptoms. In fact, evidence suggests that omega-3 fatty acid deficiency can further drive alterations in body dysmorphia and distorted body image, underscoring eating disorder pathology.
Neurobiological alterations including serotonin and dopamine have been demonstrated in eating disorder pathology. These are important modulators that support signaling pathways in the body, amongst a number of other integral functions. Altered levels of these neuromodulators have been shown to be involved in eating disorders and are suggested to play a role in reinforcing behaviors as they affect perception, hunger, satiety, mood, behavior and reward pathways relative to EDs.Eating disorder behaviors can further perpetuate these imbalances and emotional dysregulation.
GI function and microbiome balance are compromised in those with eating disorders, which can affect the balance of other systems.The gut is a key regulator of homeostatic processes in the body, affecting food intake, mood, and behavior. Altered levels of GABA and neuropeptides have been found. A lack of diversity within the gut microbiome is evident in eating disorders. Dysbiosis, the imbalance of gut bacteria, has also been suggested to have an etiological role. Gut health is important as 95% of Serotonin is made in the gut and nearly 50% of dopamine; Important for regulatory processes in the body. GABA is also produced in the gut and impacts EDs.
Dysregulation of hormone signaling pathways. Neuroendocrine dysfunction contributes via effects on reward circuitry. Altered by microbiome imbalances and nutritional deficiencies; Further drives biochemical alterations. Hormones affect different brain regions in the hypothalamus relative to feeding behaviors including Leptin, Ghrelin, CCK, peptide YY.
Nutritional deficiencies along with gut & hormonal imbalances drive systemic inflammation and oxidative stress. Pediatric acute-onset neuropsychiatric syndrome (PANS) and AN have been linked in the literature, as well as Celiac Disease & EDs. A 2021 meta-analysis conveyed high prevalence of EDs in patients with CD. Moreover, there was a significant bidirectional association between CD and EDs.
Sufficient nutrition, emotional regulation and stress management, as well as encouraging mind-body attunement to be aware of the body’s signaling/communication when thirsty, tired and hungry or stressed. Addressing these underlying contributing causes involved in eating disorder pathology can offer more efficacious treatments for these serious conditions.
Nutritional considerations for eating disorders include re-integrating nourishing foods that address macronutrient and micronutrient needs and support gut health and digestion. It is imperative to restore body weight depending on individual needs with appropriate ratios of macronutrients. Consuming smaller meals gradually throughout the day can support the refeeding process. Refeeding, rehydrating, and restoring body weight should all occur under the supervision of a medical professional. Ensuring sufficient hydration and addressing electrolyte imbalances is also significant, as many compensatory and food restriction behaviors affect electrolyte status Supporting a healthy relationship with food, body image, and emotional regulation/support are all important factors in ED treatment and recovery.
Balanced Diet and Food Choices for Adolescents
Adolescence is a critical period for physical and emotional development, making it essential for adolescents to maintain a balanced diet that meets their nutritional needs. A balanced diet during this stage of life plays a pivotal role in supporting growth, maintaining a healthy weight, and preventing chronic health issues.
The key components of a balanced diet include:
- A diverse variety of Fruits and Vegetables
- Whole Grains, Legumes, Nuts & Seeds
- Lean Proteins
- Healthy Fats
Portion Control and Moderation
Balanced eating also involves portion control and moderation. Adolescents often face the temptation of oversized portions, especially with the prevalence of fast food and large servings in restaurants. Educating adolescents about appropriate portion sizes and mindful eating can help them maintain a healthy weight and prevent overeating.+ body attunement– attune to needs of hunger, thirst, etc.
Making Informed Food Choices
Adolescents are exposed to numerous food choices, and it’s essential to teach them how to make informed decisions.
Read Food Labels
Adolescents should learn how to read food labels to identify nutritional content, serving sizes, and ingredient lists. This empowers them to choose foods that align with their health goals.
Limit Sugary and Processed Foods
Highly processed foods, sugary snacks, and sugary beverages can contribute to weight gain and health issues. Encourage adolescents to limit their consumption of these items and opt for healthier snacks like fresh fruit, yogurt, or nuts.
Practice Mindful Eating & Mind-Body Attunement
Encourage adolescents to pay attention to their hunger and fullness cues. Eating slowly and savoring each bite can help prevent overeating and promote a healthier relationship with food.
Plan Meals and Snacks
Planning meals and snacks in advance can prevent impulsive, unhealthy food choices. Adolescents can participate in meal planning, which can also be an opportunity to teach them about nutrition.
Cook at Home
Cooking meals at home allows for greater control over ingredients and portion sizes. Teaching adolescents basic cooking skills equips them to prepare nutritious meals.
Sports Nutrition for Adolescents
Adolescence is a time of increased physical activity and growth, making proper sports nutrition essential for young athletes. Whether they’re involved in team sports, individual activities, or simply staying active, adolescents require adequate nutrients to support their energy levels, performance, and overall health.
Active adolescents need a well-balanced diet that provides the necessary energy and nutrients to fuel their physical activities. This includes:
- Carbohydrates
- Proteins
- Fats
- Vitamins and Minerals
Pre-Exercise Nutrition
Eating a balanced meal or snack before exercise can optimize performance and prevent fatigue. Adolescents should aim for a meal rich in carbohydrates and moderate in protein and fat about 2-3 hours before physical activity. A small snack with carbohydrates and a small amount of protein can be consumed 30-60 minutes before exercise.
During Exercise Nutrition
For prolonged and intense activities, such as competitive sports, it’s essential to stay fueled during exercise. This may involve consuming sports drinks, energy gels, or easily digestible carbohydrate-rich snacks to maintain energy levels.
Post-Exercise Recovery
After physical activity, adolescents should focus on recovery. Consuming a snack or meal with carbohydrates and protein within 30 minutes of exercise can help replenish energy stores and support muscle repair. Nutrient-rich options like salmon, leafy greens, mushrooms and lentils, or a protein packed and macro balanced, nutrient dense smoothies are some good options. a turkey sandwich on whole-grain bread or a fruit smoothie with protein powder can be beneficial.
Avoiding Dehydration
Dehydration can hinder athletic performance and pose health risks. Encourage adolescents to drink water before, during, and after exercise. In hot and humid conditions, electrolyte-replenishing sports drinks may be necessary.
Adolescent Nutrition Education
Proper nutrition is the cornerstone of good health, especially during adolescence, a critical period of growth and development. However, there’s a glaring gap in nutrition education within schools, leaving many adolescents without the knowledge and skills needed to make healthy food choices. Addressing this deficiency is essential for equipping young people with the tools to lead healthier lives.
As it stands, nutrition education in many schools is limited, inconsistent, or even nonexistent. While some educational institutions incorporate nutrition into their curricula, the depth and quality of instruction can vary significantly. In some cases, nutrition education is overshadowed by other academic priorities, relegating it to a secondary role.
The consequences of inadequate nutrition education are far-reaching. Adolescents may graduate from high school without understanding fundamental concepts such as the importance of balanced diets, the role of nutrients, or the impact of food choices on their health. This knowledge deficit can lead to various issues.
- Poor Dietary Habits
- Limited Food Literacy
- Health Consequences
- Missed Opportunities
The Need for Expanded Nutrition Education
To address this deficiency, there is a pressing need to expand and improve nutrition education in schools. Schools should adopt comprehensive nutrition curricula that cover essential topics, including the benefits of a balanced diet, the role of nutrients, meal planning, and the consequences of unhealthy eating. Also, nutrition education can be integrated into various subjects, such as biology, chemistry, and home economics, to provide a holistic understanding of food and health. Teaching adolescents how to prepare nutritious meals during cooking classes for more than one semester can empower them to make healthier food choices and reduce their reliance on processed foods. As well, nutrition education should encourage critical thinking about food marketing, fad diets, and the impact of food choices on personal health and the environment.
Expanding nutrition education in schools can yield numerous benefits:
- Improved Health
- Lifelong Habits
- Empowerment
- Reduced Healthcare Costs
Healthy Eating Habits and Meal Planning for Adolescents
Developing healthy eating habits during adolescence is crucial for promoting overall well-being, supporting growth, and preventing diet-related health issues. Adolescents are at a stage where they are gaining more independence in their food choices, making it an opportune time to teach them how to make nutritious decisions and plan balanced meals.
A balanced diet provides the essential nutrients that adolescents need for growth, energy, and cognitive development. Encouraging adolescents to consume a variety of foods from all food groups ensures they receive the proper nutrients.Teaching adolescents about portion control and mindful eating can prevent overeating and promote a healthier relationship with food. Tips for portion control include: using smaller plates and bowls to help control portion sizes, encouraging adolescents to listen to their body’s hunger and fullness cues rather than eating out of habit or boredom, and discussing the importance of savoring each bite, eating slowly, and avoiding distractions like screens during meals.
Meal planning is a valuable skill that empowers adolescents to make nutritious food choices and reduce reliance on fast food or processed meals.
Set a Schedule
Establish regular meal times to create structure and help adolescents anticipate their next meal.
Involve Them
Encourage adolescents to participate in meal planning and preparation. They can help create shopping lists, choose recipes, and even cook simple meals.
Food Safety
Emphasize safe food handling practices to prevent foodborne illnesses.
Smart Food Choices
Adolescents should be educated about making smart food choices, including choosing whole, minimally processed foods over highly processed options, reading food labels, and limiting sugary and high-fat foods.
