A new study reveals that consuming sugary drinks may be linked to millions of new cases of cardiovascular (heart) disease globally. Researchers found that sugar-sweetened beverages — such as sodas, energy drinks, sweetened teas, and fruit punches — were associated with approximately 1.2 million new cases of heart disease in 2020, accounting for 3.1 percent of all new cardiovascular cases worldwide. These beverages were also linked to around 340,000 deaths globally that same year due to heart disease and type 2 diabetes-related complications.

For the study, researchers analyzed data from 184 countries spanning 30 years (1990 to 2020) to examine the health burden caused by sugary drinks. In some countries, sugary drinks were tied to as much as 23 percent of new heart disease cases.

Researchers also found that in 2020, sugary drinks may have contributed to 2.2 million new cases of type 2 diabetes worldwide. In type 2 diabetes, the body either does not produce enough insulin or becomes resistant to it, resulting in elevated blood glucose (sugar) levels over time.

How Sugary Beverages Affect Heart Health

Sugary drinks can take a significant toll on heart health. These beverages raise triglyceride levels and contribute to chronic inflammation — all of which increase the risk of heart disease. They are also linked to the buildup of visceral fat, a type of fat stored around the organs that is strongly associated with cardiovascular disease.

For people already living with heart disease, these effects are especially concerning, as managing risk factors like high cholesterol and high blood pressure is critical for preventing further heart-related complications. Eliminating or reducing sugary drinks from your diet can help lower these risks and improve overall heart health. It can also reduce your risk of other health conditions, such as type 2 diabetes.

If you’re living with heart disease and are curious about how dietary changes, such as reducing your sugar intake, might help, consider speaking with your healthcare provider or a dietitian. They can work with you to develop a heart-healthy eating plan that fits your lifestyle and supports your health goals.
