A study from Lund University published, in Frontiers in Public Health suggests that sugary drinks increase the risk of cardiovascular disease, but occasional sweet treats do not.
The research was based on data from the Swedish Mammography Cohort and the Cohort of Swedish Men, which included nearly 70,000 participants. Researchers analysed sugar consumption patterns, dividing them into three categories: sugary toppings, treats, and sweetened drinks. They monitored participants until 2019 to track cardiovascular diseases like stroke, heart failure, and atrial fibrillation.
The study found that drinking sugary beverages, like sodas and energy drinks, significantly increased the risk of ischemic stroke, heart failure, and other cardiovascular conditions. On the other hand, consuming a few sweet treats, such as cookies or cake, had a lower association with cardiovascular disease. It was noted that the people who avoided sweet treats entirely might have had restrictive diets or other health issues, which could explain their higher risk.
Experts believe sugary drinks are more harmful because they cause rapid spikes in blood sugar and insulin levels, leading to insulin resistance over time. This condition is linked to fat storage, inflammation, and damage to blood vessels—all contributing factors to heart disease. In contrast, occasional sugary treats do not create chronic overconsumption, allowing the body to process glucose normally.
The study's findings suggest that it’s not the quantity of sugar alone but also the source and frequency of intake that matter. Nutritionists recommend limiting added sugar to no more than 10% of daily calories, which for a 2,000-calorie diet is around 12 teaspoons. Choosing water or unsweetened beverages and keeping portions of sweet treats small can help manage sugar intake without significant risk.
The research highlights that while occasional indulgences in sweets are not a major concern, regular consumption of sugary drinks poses a serious threat to heart health. Cardiologists advise people to balance their sugar intake with a healthy diet and regular exercise to minimise cardiovascular risks.
