A recent study reveals a startling distinction between sugary beverages and other sweet treats when it comes to heart disease risk. The research suggests that drinking sugary drinks—such as sodas and sweetened beverages—carries a significantly higher risk for cardiovascular conditions compared to occasional indulgences in desserts like pastries and candy.
A serious threat to heart health
The study, which tracked nearly 70,000 adults in Sweden over two decades, analyzed dietary habits and linked the consumption of added sugars to the development of cardiovascular diseases. Participants who derived a larger proportion of their calories from sodas and other sugary drinks were found to have a notably higher risk of stroke, heart failure, aneurysms, and atrial fibrillation.
Researchers also examined the impact of other sources of sugar, such as toppings (e.g., honey, jam) and occasional sweet treats like ice cream and candy. The key takeaway: not all sources of sugar are equally harmful to cardiovascular health.
Drinking sugar-sweetened beverages leads to an increase in blood sugar and insulin levels, which is thought to cause internal inflammation—a key factor in many chronic diseases. “One reason that drinking sugar sweetened beverages increases the risk of these diseases is that the increased blood sugar and insulin levels lead to internal inflammation, which is the cornerstone to many diseases,” explains Samantha Heller, RD, a clinical dietitian in New York City who was not involved in the study.
Additionally, these sugary drinks may displace healthier options in the diet, reducing the intake of antioxidants, fiber, and other nutrients that help combat inflammation, Heller adds.
The surprising benefits of moderation in sweet treats
In a surprising twist, the study found that people who consumed sweets like pastries, chocolate, and candy occasionally actually had a lower risk of cardiovascular disease compared to those who completely avoided sugar. This finding suggests that a moderate approach to eating sweet treats could be more beneficial than total abstinence, which is often associated with restrictive and unhealthy dieting habits.
Lead author Suzanne Janzi, PhD candidate at Lund University in Sweden, explains, “This might reflect underlying dietary behaviors. Individuals consuming very little sugar might have very restrictive diets or might be limiting sugar due to preexisting health conditions.” These results highlight the importance of finding a balanced approach to sugar consumption, rather than completely eliminating sweet foods.
Dr. Maya Adam, a clinical associate professor at Stanford School of Medicine, concurs with this finding. “When we eliminate things we love from our diet, that’s often a hard change to maintain in the long run. The same goes for crash diets. We end up ping-ponging between periods of total abstinence and periods of overindulgence. That’s not healthy.” These insights suggest that moderation could be a more sustainable strategy for maintaining heart health in the long term.
Healthier alternatives to sugary drinks
While this study does not prove direct causation between sugary drink consumption and specific cardiovascular diseases, it underscores the importance of making healthier dietary choices, particularly in regard to beverages. Dr. Brooke Aggarwal, EdD, an expert on behavioral health and heart-healthy lifestyles, suggests several alternatives for satisfying sweet cravings without turning to sodas or sugary drinks.
“Cut back on sugary drinks and go for water sweetened with a slice of fruit instead, or tea, coffee, or milk,” advises Dr. Aggarwal, who was not involved in the study. Homemade smoothies are another great option, providing a sweet flavor along with added nutrients—without the excessive sugar content.
For those who aren’t fond of smoothies, other options like sparkling water with fruit slices or fresh mint can mimic the fruity flavors of sodas. Heller suggests starting with a mix of fruit juice and sparkling water as a less drastic shift. Finding enjoyable, sustainable substitutes is key to making lasting, heart-healthy changes.
Ultimately, the goal is to reduce the intake of sugary drinks without sacrificing flavor. “At the end of the day, dietary change is only healthy if we can sustain it over time,” Heller notes. “That’s why moderation is key!”
Rethinking sugar for heart health
The findings from this study provide critical insights into how different types of sugar affect heart health. Sugary drinks, especially sodas, pose a significant risk for cardiovascular disease, whereas occasional consumption of sweet treats appears to carry a lower risk. The key takeaway is that a balanced approach to sugar consumption, with an emphasis on moderation and healthier alternatives, may be the best strategy for maintaining long-term heart health.
