In India, the situation is more alarming that millions of teenagers are being affected by poor diet quality and improper nutritional level.
The period of adolescent is a phase for rapid growth in both physically and mentally. They need the proper balanced nutrients to support the height gain, development of brain, hormonal changes, immunity and for girl is future reproduction.

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 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.
Adolescence builds on earlier childhood growth, understand this foundation in our guide on Early Childhood Development in India (0–6 Years).
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.
Proper nutrition during adolescence also helps prevent long-term developmental issues—learn more in Global Developmental Delay in Children.
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 |

What is Malnutrition?
Malnutrition is the lacking of balance of nutrients in the body- malnutrition may be in the form of 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)
Malnutrition affects all age groups from infants to teenagers, read about early nutrition in Right Food Supplementation for Babies After 6 Months.
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.
Iron deficiency is one of the most common nutritional problems, explore causes and treatment in Iron Deficiency Anemia: Causes, Symptoms & Treatment.
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.
