Unpacking the Sugar Content in Fizzy Drinks
For many years, fizzy drinks have been a staple in diets around the world, known for their refreshing, bubbly taste. But behind the effervescence lies a significant health concern: the high level of added sugar. These beverages, also known as carbonated soft drinks, sodas, or pop, are a primary source of free sugars in many people's diets. The sugar content is often derived from sucrose or high fructose corn syrup, which are added during the manufacturing process to enhance flavor.
Why so much sugar?
Manufacturers add significant amounts of sugar to improve the palatability and appeal of their products. This intense sweetness can also create a craving effect, encouraging regular consumption. A study by Queen Mary University of London found that many sugary fizzy drinks contain levels far exceeding daily recommended sugar intake guidelines for both adults and children. This overconsumption of liquid calories, which do not create the same feeling of fullness as solid food, can lead to numerous health issues.
The Health Risks of High Sugar Intake from Fizzy Drinks
The health consequences associated with regular consumption of sugary fizzy drinks are well-documented and far-reaching. The Centers for Disease Control and Prevention (CDC) identifies several key health problems linked to frequent sugary drink consumption.
- Weight gain and obesity: Liquid calories are not registered by the body in the same way as solid food, leading to increased overall calorie intake. Studies show a strong link between higher consumption of sugar-sweetened beverages and increased weight gain.
- Type 2 diabetes: Strong evidence indicates a direct link between the consumption of sugar-sweetened soft drinks and the development of type 2 diabetes. The constant spikes in blood sugar and insulin levels can contribute to insulin resistance over time.
- Dental problems: The high acidity and high sugar content of fizzy drinks can damage tooth enamel, leading to tooth decay, cavities, and erosion.
- Heart disease: High added sugar intake has been linked to an increased risk of heart disease. Research has shown that sugary drinks specifically are tied to higher risks of stroke, heart failure, and aneurysms.
- Kidney and liver issues: Excessive sugar from soft drinks can also affect organ health, contributing to conditions like fatty liver disease and increasing the risk of kidney problems.
How to spot the sugar on a label
To determine the sugar content, consumers should always check the nutritional information on the product label. The key is to look at the 'Carbohydrates (of which sugars)' line, which lists the amount of free sugar per 100ml or per serving. A 'high sugar' content is generally considered to be more than 13.5g of total sugar per 100ml. Even 'no sugar added' drinks can contain naturally occurring sugars, so reading the label is essential.
The Rise of Sugar-Free Fizzy Drinks
As awareness of the negative health effects of high sugar intake has grown, so has the market for sugar-free and diet fizzy drinks. These beverages replace traditional sugar with alternative sweeteners.
Understanding sweeteners
Sugar-free drinks use sweeteners such as aspartame, sucralose, and stevia. These provide the sweet taste without the calories or blood sugar impact of traditional sugar. While the FDA has deemed these sweeteners safe for consumption within acceptable amounts, some health concerns remain and the effects of long-term consumption are still under investigation. Some studies suggest that artificial sweeteners may affect gut microbiota and glycemic control.
The comparison: Regular vs. Sugar-Free
Choosing between regular and sugar-free fizzy drinks is a complex decision. Regular versions have the significant health risks associated with high sugar consumption, including weight gain and diabetes. Sugar-free versions eliminate added sugar and calories but introduce artificial sweeteners with their own set of potential, though less certain, health considerations. For overall health, many experts recommend replacing both types with healthier alternatives like water.

| Drink (375mL Can) | Sugar per serve (g) | Sugar per serve (tsp) | Sugar per 100mL (g) |
|---|---|---|---|
| Solo | 43.1 | 10.8 | 11.5 |
| Coca-Cola (Classic) | 39.8 | 9.9 | 10.6 |
| Pepsi (Original) | 40.9 | 10.2 | 10.9 |
| Sprite | 25.9 | 6.5 | 6.9 |
| Mountain Dew | 46.1 | 11.5 | 12.3 |
| Bundaberg Ginger Beer | 40.5 | 10.1 | 10.8 |

Conclusion: Making informed choices
The answer to the question, 'Do fizzy drinks contain sugar?', is a resounding 'yes' for the vast majority of standard products. The high quantity of added sugar in these beverages is a major contributing factor to obesity, type 2 diabetes, and heart disease. While sugar-free alternatives exist, they come with their own set of considerations. The most health-conscious choice remains plain water or other unsweetened beverages. However, for those who enjoy the occasional fizzy treat, understanding the label and opting for lower-sugar varieties or smaller portions is key to making a healthier choice. It’s important for consumers to be aware of what they are drinking and the potential long-term health effects of excessive sugar consumption.
