Fast Food, Health Impacts, and Policy Responses in China and India

Area of Science:

• Public Health
• Nutrition Science
• Health Policy

Background:

• Rapid fast-food industry growth in China and India over 30 years coincides with increased overweight, obesity, and diet-related non-communicable diseases (NCDs).
• Both nations have enacted policies to mitigate health risks associated with fast-food consumption.

Purpose of the Study:

• To synthesize research on fast food's health impacts in China and India, evaluating the evidence base and comparing health outcomes.
• To compare the policy responses in China and India regarding their structure, scope, and effectiveness in addressing fast-food-related health issues.

Main Methods:

• A narrative review of 52 peer-reviewed studies published since 2010, focusing on fast food's health outcomes and policy responses in China and India.
• Inclusion of grey literature to capture recent policy developments.

Main Results:

• Evidence from China includes longitudinal and quasi-causal studies linking fast-food exposure to obesity and cardiometabolic risks. India's research primarily consists of population analyses and school-based studies reporting similar associations, including hypertension and diabetes.
• Marginalized populations in both countries are disproportionately affected, exacerbating health inequities.
• National policies in both countries emphasize education over binding regulations, showing limited effectiveness. China's centralized 'Healthy China 2030' contrasts with India's fragmented approach. Subnational interventions like zoning laws and health taxes have shown promise.

Conclusions:

• Educational policies alone are inadequate to counteract the escalating health consequences of fast-food consumption.
• There is a critical need for stronger, enforceable national regulations to modify food environments and reduce the burden of fast-food-related NCDs.
