A new study reveals that sugary drinks could significantly increase the risk of cardiovascular diseases compared to consuming occasional sweet treats like candy, ice cream, or pastries. Published in Frontiers in Public Health, the study underscores how different sources of added sugars may affect heart health in distinct ways.
Key Findings
Researchers analyzed data from nearly 70,000 adults in Sweden who completed dietary surveys in 1997 and 2009. Participants, averaging 60 years old at the start of the study, provided information about their calorie intake from three sources of added sugars: sugary drinks, toppings like honey or jam, and sweet treats. Over 20 years of follow-up, approximately 26,000 participants developed cardiovascular conditions.
The study found that higher calorie intake from sugary drinks was associated with an increased risk of heart failure, stroke, aneurysms, and atrial fibrillation. Samantha Heller, a clinical dietitian from New York City, explains that sugary drinks raise blood sugar and insulin levels, triggering inflammation—a key factor in many chronic diseases. Additionally, sugary drinks may replace healthier food choices that reduce inflammation and provide essential nutrients.
Why Moderation in Sweet Treats May Be Beneficial
Interestingly, occasional consumption of desserts like chocolate, pastries, and candy was linked to a lower risk of heart disease compared to complete abstinence from sweets. This could be due to dietary behaviors or preexisting health conditions among those who completely avoid sugar, according to Suzanne Janzi, the study’s lead author.
Dr. Maya Adam, a clinical associate professor at Stanford School of Medicine, suggests that moderation is easier to maintain than complete restriction. “Eliminating foods we love often leads to cycles of abstinence and overindulgence, which can be detrimental to health,” she explains.

Healthier Alternatives to Sugary Drinks
While the study wasn’t designed to establish causation, it provides a compelling reason to rethink sugar consumption habits. Experts recommend several healthier alternatives to sugary drinks:
- Flavored Water: Add a slice of fresh fruit or a sprig of mint to water.
- Tea or Coffee: Enjoy unsweetened versions of these beverages.
- Homemade Smoothies: Blend fresh fruits for a nutrient-rich drink with natural sweetness.
- Sparkling Water: Mix it with a splash of fresh fruit juice for a soda-like flavor.
Clinical dietitian Samantha Heller emphasizes the importance of sustainable dietary changes. “At the end of the day, dietary change is only effective if it’s manageable over time,” she notes.
Final Words
This study highlights the need to differentiate between the health impacts of sugary drinks and sweet treats. While indulging in occasional desserts might not harm heart health, regular consumption of sugary beverages poses a significant risk. Finding healthier drink alternatives and practicing moderation can make a significant difference in long-term well-being.
