1) Why Teen Nutrition Matters

During the teen years, your body and brain are growing fast. What you eat affects:

• Height, bone strength, and muscle development.
• Hormones, mood, and mental health.
• School performance, focus, and memory.
• Sports performance and recovery.
• Long‑term risk of diseases like diabetes, heart disease, and some cancers.

2) Teen Eating Habits & Patterns

Common teen eating patterns include:

• Skipping breakfast or meals due to time or body image concerns.
• Eating lots of fast food or snacks on the go.
• Drinking sugary drinks, energy drinks, or large coffees.
• Late‑night snacking while gaming or studying.
• Social eating (parties, events, celebrations).

3) Balanced Diet, MyPlate & USDA Guidelines

The MyPlate model from USDA is a simple way to picture a balanced meal:

• Half your plate: Fruits and vegetables.
• About one‑quarter: Grains (prefer whole grains when possible).
• About one‑quarter: Protein (beans, eggs, fish, poultry, lean meats, tofu, etc.).
• Dairy or fortified alternatives: Milk, yogurt, or fortified plant‑based options.

4) Macronutrients & Micronutrients

Macronutrients

• Carbohydrates: Main energy source (grains, fruits, starchy vegetables).
• Proteins: Build and repair muscles and tissues (meat, beans, eggs, dairy, tofu).
• Fats: Support brain function and hormones (nuts, seeds, oils, avocado, fish).

Micronutrients

• Iron: Important for energy and preventing anemia.
• Calcium & Vitamin D: Essential for strong bones and teeth.
• B vitamins: Help with energy and brain function.
• Vitamin C: Supports immune system and helps absorb iron.

5) Understanding Food Labels

Food labels help you see what’s in your food and how much you’re eating.

• Serving size: The amount all the numbers are based on.
• Calories: Energy per serving.
• Total fat, saturated fat, trans fat: Types of fat; aim to limit saturated and avoid trans fat.
• Sodium: Salt; high amounts can affect blood pressure.
• Total carbohydrates: Includes fiber and sugars.
• Added sugars: Sugars added during processing; aim to limit.
• Protein: Important for growth and repair.
• Vitamins & minerals: Listed nutrients like Vitamin D, calcium, iron, potassium.

6) Eating Problems & Disordered Eating

Not every eating problem is a full eating disorder, but patterns can still be harmful:

• Skipping meals to lose weight or “make up” for eating.
• Feeling guilty after eating certain foods.
• Obsessing over calories or “clean eating.”
• Using exercise as punishment for eating.
• Hiding food or eating in secret.

7) Eating Disorders (Overview)

Eating disorders are serious medical and mental health conditions that need professional help. Common types include:

• Anorexia nervosa: Restricting food intake, intense fear of gaining weight, distorted body image.
• Bulimia nervosa: Binge eating followed by behaviors to “compensate” (vomiting, over‑exercise, laxatives).
• Binge eating disorder: Eating large amounts of food with a feeling of loss of control, often with guilt or shame.
• Other specified feeding or eating disorders (OSFED): Serious patterns that don’t fit one exact category.

8) Social Eating Trends & Diet Culture

Social media and culture can shape how teens think about food and bodies:

• “What I eat in a day” videos: Often unrealistic or edited.
• Extreme diets: Cutting out entire food groups without medical reasons.
• Detoxes & cleanses: Often unnecessary and sometimes harmful.
• Body comparison: Comparing your body to filtered or edited images.
• Food shaming: Judging yourself or others for what they eat.

9) Food Safety, Food Poisoning & Foodborne Disease

Food poisoning happens when you eat food contaminated with harmful bacteria, viruses, or toxins. Symptoms can include nausea, vomiting, diarrhea, stomach cramps, and fever.

Common Causes

• Undercooked meat, poultry, or eggs.
• Unpasteurized milk or juices.
• Food left out at room temperature too long.
• Cross‑contamination (raw meat touching ready‑to‑eat foods).
• Unwashed fruits and vegetables.

Basic Food Safety Rules

• Clean: Wash hands, surfaces, and produce.
• Separate: Keep raw meat away from other foods.
• Cook: Cook foods to safe internal temperatures.
• Chill: Refrigerate leftovers promptly.

Food safety info: FoodSafety.gov

10) Special Diets & Allergies

Some teens have medical or personal reasons for specific diets:

• Food allergies: Reactions to foods like peanuts, tree nuts, milk, eggs, wheat, soy, fish, shellfish.
• Intolerances: Such as lactose intolerance or gluten sensitivity.
• Medical diets: For conditions like celiac disease, diabetes, or kidney disease.
• Ethical or cultural diets: Vegetarian, vegan, religious dietary rules.

If you follow a special diet, it’s important to make sure you still get enough nutrients. A doctor or registered dietitian can help.

11) Building Healthy Eating Habits

Healthy eating is a journey, not a test you pass or fail.

• Add fruits or vegetables to most meals.
• Drink more water and fewer sugary drinks.
• Eat regular meals (including breakfast if possible).
• Listen to hunger and fullness cues.
• Enjoy treats without guilt, but not as your main food group.
• Cook simple meals or snacks when you can.
