High-Fructose Corn Syrup vs. Sucrose: The Primary Contenders
The vast majority of sweetened soft drinks use one of two main caloric sweeteners: high-fructose corn syrup (HFCS) or sucrose. Their use is often determined by regional availability, cost, and tradition.
What is High-Fructose Corn Syrup?
HFCS is a liquid sweetener derived from corn starch. It became widely used in the U.S. during the 1970s, partly due to its cost-effectiveness supported by government corn subsidies. The type most common in beverages, HFCS 55, contains approximately 55% fructose and 42% glucose.
What is Sucrose?
Sucrose is common table sugar, obtained from sugarcane or sugar beets. It is a disaccharide where glucose and fructose are chemically bound in a 50/50 ratio. This is the sweetener frequently found in sodas outside the U.S.
The Breakdown: Why Pop Contains Multiple Sugars
Even in sodas made with sucrose, glucose and fructose are present as individual molecules. This occurs because the acidic nature of soft drinks causes sucrose's bond to break through hydrolysis, converting sucrose into a mix of free glucose and fructose over time.
The Rise of Artificial and Blended Sweeteners
Driven by health concerns and the demand for lower-sugar options, manufacturers utilize various other sweeteners.
Artificial Sweeteners (Calorie-Free):
- Aspartame: Found in Diet Coke and other diet drinks, roughly 200 times sweeter than sugar.
- Sucralose: About 600 times sweeter than sugar and used in many zero-sugar products.
- Saccharin and Acesulfame K: Often combined to improve flavor and minimize aftertaste.
Blended Sweeteners:
- Some drinks mix sucrose with low-calorie sweeteners to lower total sugar.
HFCS vs. Sucrose: A Comparative Look
| Feature | High-Fructose Corn Syrup (HFCS) | Sucrose (Table Sugar) |
|---|---|---|
| Source | Corn Starch | Sugarcane or Sugar Beets |
| Chemical Structure | Mixture of free glucose and fructose. | Bonded glucose and fructose. |
| Ratio (in beverages) | HFCS 55: 55% fructose, 42% glucose. | 50% fructose, 50% glucose. |
| Form | Liquid. | Crystalline. |
| Cost | Historically cheaper. | Can be more expensive. |
| Metabolism | Metabolized similarly to sucrose after digestion. | Broken down into glucose and fructose before absorption. |
The Bottom Line on Pop's Sugar
Regardless of whether pop contains HFCS or sucrose, it provides a significant amount of simple sugars. While debates have existed, research indicates similar metabolic effects. Health experts emphasize that the primary concern is the total intake of added sugar, not the specific type. Checking nutrition labels and moderating consumption of sugary drinks are key for health.

Conclusion
Understanding what kind of sugar is in pop involves recognizing the common use of HFCS in the U.S. and sucrose internationally. The acidity of sodas causes sucrose to break down into glucose and fructose over time, resulting in a mix of sugars in many regular drinks. Diet options rely on artificial sweeteners to avoid calories. The most important health message is to reduce overall intake of added sugars.
