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.

| Indicator | Global / India Estimate | Source | Publication Year |
|---|---|---|---|
| Adolescents worldwide | ~1.2 billion individuals | WHO | 2023 |
| Adolescents affected by anemia globally | ~30% of girls aged 15–19 | WHO Global Health Observatory | 2022 |
| Adolescents in India (10–19 years) | ~253 million | UNICEF India | 2023 |
| Adolescents with anemia in India | ~59% girls (15–19 years) | NFHS-5 | 2021 |
| Underweight among adolescents in India | ~24% | UNICEF Nutrition Report | 2022 |
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:
- Iron deficiency – Check in Amazon
- Anemia – Check in Amazon
- Iodine deficiency
- Deficiency of vitamin A, D, C and B-complex. – Check in Amazon
- Zinc deficiency
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.

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.

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 |
