Why Healthy Food is Important for Adolescents?

Adolescence (10-19 years) refers to the time when an individual enjoys a rapid physical, emotional and mental development. At this age, the body needs proper nutrition to help in increasing the height of the body, development of the muscles, good bones, development of the brain, hormonal stability and the body should have fine immune system. Eating well in the teenage years helps in minimizing infections, anemia, obesity and most of the health issues in the future.

Nutrition is beneficial to teenagers:

  • Stay energetic and active
  • Come out better academically.
  • Build stronger immunity
  • Keep body weight in great condition.
  • Improves mood stability and concentration.

Global and national reports have indicated that adolescents have various nutritional problems such as under nutrition, deficiency of micronutrients and increasing obesity.

What is Malnutrition?

Malnutrition is the term that is used to describe the lack of balance of nutrients in the body- malnutrition may be in the form of having less, excess, or low quality of nutrition. It is common among children, adolescents, pregnant women and nursing mothers.

Types of Malnutrition

Type of Malnutrition Description Common Causes
Under-nutrition Insufficient intake of energy or nutrients Poverty, food insecurity
Micronutrient Deficiency Lack of vitamins or minerals Poor diet diversity
Overweight & Obesity Excess calorie intake relative to expenditure Processed food consumption, sedentary lifestyle

Source: WHO – Healthy Diet Guidelines (2023)

There are three major types of Malnutrition:

1. Under-nutrition

This is brought about by the lack of sufficient nutrients in the body. It may result in:

  • Wasting: low weight for height
  • Stunting Low stature at age owing to chronic malnutrition.
  • Underweight: Low weight for age

The result of under-nutrition may be low immunity, ill health, lack of learning performance, retarded growth and physical weakness.

2. Micronutrient Deficiency

This occurs in cases where the body does not have essential vitamins or minerals. Some of the most frequent shortcomings are:

These can lead to tiredness, immuno-suppression, impaired brain performance, slow wound recovery among other complications.

3. Overweight & Obesity:

Over-nutrition is gradually growing more prevalent in the adolescent population particularly the low-income and urban nations. Over-nutrition occurs when calorie intake is higher than calorie expenditure. It may lead to:

  • Risk of diabetes
  • Heart disease later in life
  • Joint and mobility issues
  • Low self-confidence
  • Hormonal imbalances

It is necessary to prevent it by balanced diets and physical exercises.

The Vitamins, Minerals Your Teenager Should Have

A healthy meal is the appropriate proportion of both macro and micro nutrients.

Carbohydrates

  • Provide energy
  • Support brain function
  • Healthy sources:

    • Whole grains
    • Brown rice
    • Oats
    • Millets
    • Whole-wheat bread

Proteins

  • Build and repair muscles
  • Support growth
  • Healthy sources:

    • Milk & milk products
    • Eggs
    • Fish & chicken
    • Pulses & beans
    • Soy & nuts

Fats:

  • Provide energy
  • Support brain development
  • Healthy sources:

    • Nuts & seeds
    • Healthy oils (olive, mustard)
    • Milk products (in moderation)

Vitamins & Minerals

  • Boost immunity
  • Improve skin & eye health
  • Strengthen bones

Key nutrients:

  • Iron
  • Calcium
  • Vitamin A, C, D & E
  • Zinc

Important Micronutrients for Adolescents

Nutrient Role in Body Food Sources
Iron Supports oxygen transport in blood Green leafy vegetables, beans
Calcium Supports bone growth Milk, yogurt
Vitamin A Supports vision and immunity Carrots, mangoes
Vitamin D Helps calcium absorption Sunlight, fortified foods
Zinc Supports immune function Nuts, seeds

Water

Hydration is essential for:

  • Brain function
  • Digestion
  • Temperature control

Adolescents are expected to consume 6-8 glasses of water per day, which should be increased after exercise.

Macronutrients and Their Role in Adolescent Nutrition

Nutrient Main Function Healthy Food Sources
Carbohydrates Provide energy for daily activities Whole grains, rice, oats
Proteins Support growth and muscle repair Eggs, milk, legumes
Healthy Fats Support brain development Nuts, seeds, vegetable oils

Deficiency of Micronutrients among Adolescents: A Global Challenge

  • Among teens, and girls in particular, iron deficiency and anemia is very common.
  • The deficiency of iodine remains prevalent in several nations.
  • Unhealthy eating and ignorance are risk factors.

These deficiencies can be greatly reduced by ensuring that a person has a nutrient-rich diet and frequent health check-ups.

Common Micronutrient Deficiencies Among Adolescents

Nutrient Deficiency Estimated Global Prevalence Source Year
Iron deficiency anemia ~30% adolescent girls WHO 2022
Iodine deficiency ~2 billion people at risk UNICEF 2021
Vitamin A deficiency ~190 million children globally WHO 2022
Zinc deficiency risk ~17% of global population FAO 2020

Daily nutrition requirements in the adolescence stage.

In the course of teenage development spurts:

  • Boys require more calories to make muscle development.
  • The girls require increased iron because of menstruation.
  • The two require increased intake of calcium and proteins to help in bone growth.

Adequate nutrition enables adolescents to study, participate in sports, be active, and have good health.

Recommended Daily Nutrient Intake for Adolescents

Nutrient Boys (14–18 yrs) Girls (14–18 yrs) Source
Energy ~2800 kcal ~2200 kcal ICMR-NIN 2020
Protein ~52 g ~46 g ICMR-NIN 2020
Calcium 1000 mg 1000 mg WHO 2023
Iron 11 mg 15 mg WHO 2023
Water ~2–2.5 L ~2 L EFSA 2022
