This article explores the global health risks of sugar-sweetened beverages (SSBs), linking their consumption to increased cases of type 2 diabetes (T2D) and cardiovascular disease (CVD). A study covering 184 countries found that in 2020 alone, SSBs contributed to 2.2 million new T2D cases and 1.2 million new CVD cases. Regional and demographic disparities highlight the need for targeted interventions. To combat these risks, public health measures such as taxation, advertising restrictions, and educational programs are essential. The message is clear: reducing SSB intake can significantly improve global health outcomes.
In today’s modern lifestyle, sugar-sweetened beverages (SSBs) are omnipresent, becoming an integral part of many people’s daily diets. Whether it’s cooling down with an ice-cold soda on a scorching summer day or celebrating holidays and gatherings with sugary drinks, these beverages have seamlessly woven themselves into our lives. However, behind their refreshing taste lies a significant health risk.
A recent study published in Nature Medicine, titled "Burdens of Type 2 Diabetes and Cardiovascular Disease Attributable to Sugar-Sweetened Beverages in 184 Countries", sheds new light on this issue. The research incorporates extensive global, regional, and national data from 1990 to 2020, analyzing the impact of SSBs on diverse populations across 184 countries. The findings confirm a strong correlation between SSB consumption and the prevalence of type 2 diabetes (T2D) and cardiovascular disease (CVD), while also revealing unexpected trends across different demographics and regions.
Study Background
The consumption of SSBs has surged worldwide, contributing to excessive sugar intake, weight gain, and metabolic disorders, ultimately increasing the risk of T2D and CVD. While prior studies have established links between SSBs and adverse health outcomes, a comprehensive global assessment of the disease burden has been lacking. To address this gap, researchers utilized the most up-to-date data at the global, regional, and national levels.
Study Methods
- Data Sources: The study derived SSB intake data from the Global Dietary Database (GDD), incorporating 450 surveys covering 2.9 million individuals from 118 countries—representing 87.1% of the global population. These individual dietary records provided a more accurate reflection of SSB consumption patterns across diverse groups.
- Model Construction: Using the Comparative Risk Assessment (CRA) model, the study evaluated the contribution of SSBs to T2D and CVD while accounting for variables such as age, gender, education level, and urban-rural residence. Monte Carlo simulations were employed to estimate the disease burden with confidence intervals.
- Statistical Analysis: Bayesian hierarchical models and Monte Carlo simulations were used to quantify the impact of SSB intake on weight gain and subsequent risk increases for T2D and CVD.
Key Findings
1. Global SSB Consumption and Disease Burden
- SSB Intake: In 2020, the global average SSB consumption was 2.6 servings per week (8 ounces per serving). The highest intake was observed in Latin America and the Caribbean (7.3 servings/week), while the lowest was in South Asia (0.7 servings/week).
- Disease Burden: SSB consumption was responsible for approximately 2.2 million new cases of T2D and 1.2 million new cases of CVD worldwide in 2020, accounting for 9.8% and 3.1% of total cases, respectively. The resulting disability-adjusted life years (DALYs) reached 12.5 million, with 5 million attributed to T2D and 7.6 million to CVD.

2. Regional and National Disparities
- Regional Differences: The highest rates of SSB-related T2D and CVD were found in Latin America and the Caribbean, while Southeast Asia and East Asia had the lowest rates.
- Country-Specific Trends: Among the 30 most populous countries, Mexico, Colombia, and South Africa recorded the highest numbers of SSB-related T2D and CVD cases.

3. Sociodemographic Variations
- Gender: Men had a slightly higher burden of SSB-related T2D and CVD than women.
- Age: The relative impact of SSBs on T2D and CVD was highest among younger individuals, but the absolute number of cases was highest in middle-aged and older adults.
- Education Level: In Sub-Saharan Africa, South Asia, and Latin America, higher-educated individuals consumed more SSBs and experienced a greater disease burden. However, in the Middle East and North Africa, the trend was reversed.
- Urban vs. Rural Divide: In Sub-Saharan Africa and South Asia, urban residents had higher SSB consumption, while in the Middle East and North Africa, rural residents consumed more.

4. Trends Over Time
- Global Changes: Between 1990 and 2020, the T2D incidence attributed to SSBs increased by 1.3 percentage points, while CVD incidence remained relatively stable.
- Regional Shifts: The greatest increase in SSB-related disease burden was observed in Sub-Saharan Africa, while Latin America and the Caribbean saw slight declines but still maintained the highest overall burden.

Conclusions and Public Health Implications
This study underscores the immense disease burden posed by SSB consumption, particularly in specific regions and demographic groups. To mitigate these risks, governments, public health organizations, and individuals must take proactive measures by implementing comprehensive prevention and intervention strategies. Key policy recommendations include:
-
Taxation on SSBs to discourage consumption
-
Stricter advertising regulations targeting youth and vulnerable groups
-
Improvements in school nutrition programs to promote healthier alternatives
-
Public awareness campaigns to educate consumers about the dangers of excessive sugar intake
The findings also highlight the need to address educational disparities in SSB consumption, as well as the influence of socioeconomic status on dietary habits. By recognizing the widespread impact of SSBs on public health, we can work towards reducing their consumption and fostering healthier beverage choices globally.
Final Thought: A Sweet Taste, A Hidden Danger
While sugar-sweetened beverages may seem like harmless indulgences, their contribution to global T2D and CVD cases is alarming. With this study providing a clearer picture of their health risks, it’s time to rethink our daily drink choices. For the sake of our health and future well-being, let’s take the first step today—cut back on SSBs and opt for healthier alternatives.
