Rising NCDs, Not Consumption, Drive Sugar Taxes In Asia

The study from the Food is Medicine Institute at the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, Tufts University, said that governments are accelerating policy adoptions to mitigate surging healthcare costs and productivity losses associated with diet-related non-communicable diseases (NCDs).

The first of its kind to systematically track global adoption across 183 countries, the study highlights a striking regional pattern. South Asia leads globally, with nearly 50% of countries implementing such taxes, followed closely by Southeast and East Asia at about 48%. In contrast, adoption remains significantly lower in regions such as Central and Eastern Europe.

Researchers said the findings underscore a widening global recognition that sugary drink consumption is not merely a lifestyle issue but a major driver of NCDs, particularly in low- and middle-income countries, where healthcare systems are already under strain.

One of the most important findings of the study is the disconnect between consumption patterns and policy action.

“Surprisingly, the consumption rates of sugar-sweetened beverages had no significant relationship with whether a country chose to tax them, suggesting these decisions are driven more by disease burdens,” said Lizbeth Moreno Loaeza, first author of the study, who conducted the research while at the Friedman School. Currently, he is associated with the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City.

The analysis found that countries with higher rates of type 2 diabetes and obesity were significantly more likely to adopt SSB taxes, even when sugary drink consumption itself was not the primary trigger.

“We also found that countries with higher social and health development are less likely to adopt these taxes, regardless of their economic wealth,” Moreno Loaeza added. “This may be because they generally possess more robust health systems and experience lower rates of diet-related diseases.”

The research drew on large global datasets spanning more than three decades, including the Global Burden of Disease Study, Global Dietary Database, and World Bank indicators.

Public health experts said the findings come at a critical moment for India, where rapid urbanisation, changing diets, and aggressive marketing of ultra-processed beverages are contributing to a sharp rise in metabolic disorders.

A 2025 analysis cited in the study estimated that sugar-sweetened beverages are responsible globally for 2.2 million new diabetes cases and 1.2 million cardiovascular disease cases every year—figures that underscore their growing public health impact.

India, already home to one of the world’s largest diabetic populations, is witnessing increasing consumption of packaged soft drinks, energy drinks, and sweetened juices, particularly among young people and urban populations. Health experts warn that this trend is adding to the country’s already heavy NCD burden.

The Tufts study shows that while 29% of high-income countries have adopted SSB taxes, only 17% of countries in Central and Eastern Europe and Central Asia have done so, highlighting global inequities in policy response.

Even where taxes exist, their design varies widely. Rates range from 1% to 34% across countries, with most levies based on volume or price rather than sugar content.

Researchers suggest this is a missed opportunity.

“Only a small fraction tied the tax to sugar content, an approach the researchers say may be most effective because it pushes beverage companies to reduce sugar in their products,” the study notes.

Another major gap is in the use of revenue generated from such taxes. The study found that only 13% of countries channel tax revenues into health programmes, limiting their broader public health impact.

Public health specialists say India’s experience mirrors the global findings. While some states have experimented with taxation on sugary drinks under broader GST structures, there is no dedicated, nationally coordinated SSB tax framework linked to health outcomes.

Experts argue that such a policy could serve dual goals: reducing consumption and generating revenue for public health programmes, especially for diabetes prevention and primary care strengthening.

“These findings highlight opportunities to continue to advance nutrition and well-being through sensible policies, like soda taxes, around the world,” said Dariush Mozaffarian, senior author of the study and Director of the Food is Medicine Institute.

Mozaffarian emphasised that nearly half of the world’s population now lives under some form of sugar-sweetened beverage tax, but rates remain relatively low in many countries.

In India, the health consequences of poor dietary patterns are already visible in rising rates of obesity among adolescents, increasing early-onset type 2 diabetes, and growing incidence of hypertension.

Doctors warn that the burden is not only clinical but also economic. Families face long-term treatment costs, loss of productivity, and increasing strain on public healthcare systems.

Urban centres, where sugary drink consumption is highest, are also reporting higher rates of lifestyle-related metabolic disorders in younger age groups—sometimes even in individuals below 30 years.

The Tufts analysis suggests that while global momentum on SSB taxation is increasing, there remains significant room for expansion and refinement. Experts argue that countries like India, with large youth populations and rapidly changing dietary patterns, stand at a critical policy crossroads.

Health economists believe that well-designed sugar taxes—particularly those linked to sugar content and reinvested into health programmes—could play a significant role in curbing future disease burden.

As NCDs continue to rise, the study concludes that sugar taxation is no longer just a fiscal instrument but an essential public health intervention.
