The Facts

  • According to a study published in Nature Medicine on Monday, sugar-sweetened beverages resulted in 2.2M new cases of Type 2 diabetes and 1.2M cardiovascular disease cases, resulting in about 340K deaths in 2020.

  • The research analyzed data from 450 surveys among 2.9M individuals across 118 countries and found that adults consume an average of 2.6 eight-ounce servings of sugary drinks weekly.

  • Latin America and the Caribbean face the highest impact, with sugary drinks contributing to about 24% of new diabetes cases and over 11% of cardiovascular disease cases in 2020.


The Spin

Narrative A

The rapid increase in sugary drink consumption poses a severe public health crisis, particularly in developing nations where health care systems are ill-equipped to handle the surge in diet-related diseases, and aggressive marketing targets vulnerable populations. We need urgent, evidence-based interventions to curb the consumption of sugar-sweetened beverages globally.


Narrative B

Several factors, including unhealthy diet and lack of exercise, cause Type 2 diabetes. Key risk factors for heart disease include high cholesterol and smoking. Therefore, this sugary drink study should be taken with a metaphorical pinch of salt — more so because it could neither definitively prove cause and effect nor test a behavior or intervention against a control group.
