Are Sugary Drinks Really That Bad for Your Heart?

Americans have a long-standing love affair with sugary drinks, from fizzy sodas to sweetened fruit beverages. The Center for Disease Control and Prevention reports that almost half of American adults drink at least one sugar-sweetened beverage every day.

We know consuming excessive added sugars from any source can lead to negative health outcomes, including increased risk of obesity, heart disease, and dental cavities. But a new study published in Frontiers in Public Health suggests that sipping on sugary drinks could be more harmful to our health than other sources of added sugar.

How Was the Study Conducted and What Did It Find?

The study analyzed data from 69,705 Swedish adults aged 45 to 83 over 22 years. Researchers examined the link between added sugar intake from three categories:

• Sugar-sweetened drinks: This included sodas, fruit drinks, and sweet tea made with sugar.
• Treats: Pastries, ice cream, chocolate, and sweets
• Toppings: Table sugar, honey, jams, and marmalades

After analyzing the relationship between sugar consumption and seven cardiovascular diseases, researchers found a connection between added sugar intake (from any source) and increased risk of:

• Ischemic stroke: A stroke that occurs when a blood clot blocks an artery in the brain.
• Abdominal aortic aneurysm: A bulge in the aorta, the main artery supplying blood to the body.

Specifically, consuming more than eight servings of sugar-sweetened drinks per week was linked to:

• 19% higher risk of ischemic stroke
• 18% higher risk of heart failure
• 11% higher risk of atrial fibrillation (a type of irregular heartbeat)
• 31% higher risk of abdominal aortic aneurysm

Interestingly, low consumption of treats was associated with a higher risk of all studied outcomes. However, researchers suggest this finding requires further investigation.

What Does This Mean?

Sugary drinks are a significant contributor to added sugar intake. One regular soda contains approximately 39 grams of added sugar, which is more than the American Heart Association’s recommended daily intake. This study highlights that sugary drinks, in particular, may be major culprits driving the risk of cardiovascular disease.

The authors of the study offer possible explanations for the differences seen between sugary drinks, treats, and toppings. They suggest that liquid calories tend to provide lower satiety than solid foods. This may lead people to consume more calories overall without compensating by reducing intake elsewhere, potentially contributing to weight gain and obesity, a known risk factor for heart disease.

They also highlight the social aspect of treat consumption, noting that ”fika,” a Swedish tradition of gathering for coffee and pastries, could explain the link between treats and lower heart health risk.

How Does This Apply to Real Life?

Here are some tips to limit your sugar-sweetened beverage intake and promote heart health:

• Read Labels: Pay attention to ingredient lists and nutrition facts labels. Look for words like "added sugar," "syrup," or "sweetener."

• Choose Water or Unsweetened Beverages: Make water your go-to drink. Opt for unsweetened flavored options like sparkling water or herbal tea.

• Go for 100% Fruit Juice: If you crave fruit flavor, choose 100% fruit juice without added sugars. Be sure to consume in moderation due to natural sugar content.

• Look for Lower-Sugar Sodas: Consider sodas with added nutrients or probiotics while choosing lower-sugar options.

• Make Your Own Refreshments: Get creative! Infuse water with fruits, herbs, or cucumber for a flavorful and sugar-free option.

The Bottom Line

While added sugars can be detrimental to heart health, the type and source of sugar matter.
