Context

• India is facing a double burden of malnutrition, where persistent undernutrition coexists with rising obesity and lifestyle diseases.
• Increasing cases of diabetes, hypertension, and cardiovascular diseases among young people indicate that these conditions originate much earlier than adulthood.
• Adolescence is a crucial stage for developing lifelong dietary and lifestyle habits, making schools the ideal institutions for preventive action.
• By promoting nutrition literacy, healthy eating, and physical activity, schools can play a transformative role in improving public health.

Double Burden of Malnutrition

• Malnutrition is no longer limited to hunger or thinness. India now experiences both stunting and excessive weight gain simultaneously.
• A significant concern is the thin-fat phenotype, where children appear lean but possess high metabolic risk, making them vulnerable to adult-onset diabetes and heart disease.
• This demonstrates that body appearance alone is not an accurate indicator of nutritional health.
• Addressing both forms of malnutrition requires comprehensive interventions that focus on balanced nutrition rather than calorie intake alone.

Promoting Balanced Nutrition in Schools

• Many adolescents consume diets dominated by cereals while lacking sufficient proteins, fruits, vegetables, and dairy products.
• Such dietary patterns contribute to poor growth, micronutrient deficiencies, and long-term metabolic disorders.
• Schools should strengthen midday meals, introduce healthier canteens, establish school gardens, and encourage the use of seasonal local produce.
• Nutrition education should emphasize balanced meal planning, ensuring that half of every plate consists of fruits and vegetables while providing adequate protein and essential nutrients.

Addressing Sugar, HFSS Foods, and Ultra-Processed Foods

• The growing popularity of High Fat, Sugar and Salt (HFSS) foods and Ultra-Processed Foods (UPFs) has significantly worsened adolescent nutrition.
• Frequent consumption of sugary drinks and processed snacks increases the risk of obesity and chronic diseases.
• Schools should discourage unhealthy food choices by creating UPF-free school zones, displaying information on hidden sugar content, and promoting healthier alternatives.
• Continuous awareness programmes are more effective than one-time campaigns in shaping lasting behavioural change.

Promoting Physical Activity

• Poor nutrition is closely linked with physical inactivity and increasing screen time.
• Reduced participation in sports has contributed to rising obesity across both urban and rural areas.
• Schools should make regular exercise, sports, and outdoor activities compulsory rather than optional.
• Daily physical activity improves physical fitness, reduces the risk of non-communicable diseases, and supports better mental and emotional well-being.
• Healthy diets and active lifestyles must complement each other to produce lasting health benefits.

Policy Support and Public Health Initiatives

• Strong institutional support is essential for sustainable change.
• The Let's Fix Our Food (LFOF) initiative led by ICMR-NIN promotes healthier food environments through evidence-based policies, nutrition education, food-label reading, regulation of unhealthy food advertising, and taxation of sugary beverages.
• Such initiatives empower students to make informed dietary choices while encouraging schools to adopt comprehensive nutrition programmes that extend beyond classroom instruction.

Conclusion

• The growing burden of adolescent malnutrition threatens India's future health and economic productivity.
• Preventing obesity, diabetes, and cardiovascular diseases requires interventions long before adulthood.
• Schools should evolve into public health-promoting institutions by integrating balanced nutrition, food literacy, healthy food environments, and compulsory physical activity into everyday education.
• Investing in healthier children today will reduce future healthcare costs, improve quality of life, and build a healthier, more productive nation.
