A comprehensive national diet survey (ICMR-INDIAB 2024) maps India's dietary crisis and its link to rising non-communicable diseases.

• Refined carbohydrates: 62 per cent of average Indian dietary energy comes from refined carbohydrates such as white rice and refined wheat flour.
• Ultra-processed food growth: Rural spending on ultra-processed foods has grown 353 per cent since 1999. This is a structural shift in consumption patterns.
• Disease burden: ICMR estimates that poor diet is responsible for 56.4 per cent of India's total disease burden.
• Diabetes: Approximately 101 million Indians live with diabetes.
• WHO data: The World Health Organization reports that non-communicable diseases account for 66 per cent of all deaths in India.
• Policy gap: India has no mandatory front-of-pack nutritional warning labelling system despite FSSAI proposals since 2022.

A study by the MS Swaminathan Research Foundation documents a link between extreme heat exposure and adverse gynaecological outcomes among female agricultural workers.

• Study population: Female sugarcane workers in Beed district of Maharashtra.
• Key finding: Women in high-heat zones have twice the hysterectomy rate compared to women in cooler areas in the same occupation.
• Mechanism: Extreme heat causes dehydration and chronic physical strain. Workers lack access to shade, water or rest breaks.
• Textile sector parallel: Female textile workers in Tamil Nadu restrict water intake during heatwaves to avoid needing toilet breaks. This causes urinary tract infections.
• Policy gap: India's Occupational Safety, Health and Working Conditions Code 2020 does not include heat-stress standards for outdoor agricultural workers.
• MSSRF mandate: The MS Swaminathan Research Foundation is a Chennai-based research institution focused on agriculture, ecology and community welfare.
