Total Sugar Content: Comparing Standard Cans
At first glance, a standard 12-ounce can of Coca-Cola appears to have significantly more sugar than the smaller, standard 8.4-ounce can of Red Bull. This is a common point of confusion for consumers.
- Coca-Cola (Original): A single 12 fl oz can contains 39 grams of sugar.
- Red Bull (Energy Drink): An 8.4 fl oz can has 27 grams of sugar. By these figures, Coke has 12 more grams of sugar per can. However, this comparison is skewed due to the different volumes. To understand the true sugar concentration, it's essential to look at the amount of sugar per fluid ounce.
Sugar Density: Grams per Ounce
When you normalize the data by calculating the sugar content per ounce, a clearer picture emerges. This metric shows the concentration of sugar in each drink, regardless of the container size.
- Coca-Cola: 39 grams / 12 fl oz = 3.25 grams of sugar per fluid ounce.
- Red Bull: 27 grams / 8.4 fl oz ≈ 3.21 grams of sugar per fluid ounce. Based on these calculations, the sugar concentration is nearly identical. This means that for every sip, you are consuming a very similar amount of sugar from either beverage. The difference lies solely in the volume of the standard serving size.
Bigger Cans Mean More Sugar
While the per-ounce comparison is important, many people consume larger sizes of these drinks. The total amount of sugar consumed is what impacts your health.
- Large Coke: A 20 fl oz bottle of Coca-Cola contains 65 grams of sugar.
- Large Red Bull: A 16 fl oz can of Red Bull contains 52 grams of sugar. In these larger sizes, the total sugar and calorie intake escalates rapidly, potentially pushing you well over daily recommended limits.
A Quick Comparison: Coke vs. Red Bull
| Feature | Coca-Cola (12 fl oz) | Red Bull (8.4 fl oz) | 
|---|---|---|
| Total Sugar | 39g | 27g | 
| Sugar per fl oz | 3.25g | ~3.21g | 
| Total Calories | 140 | 110 | 
| Caffeine | ~34mg | ~80mg | 
| Other Ingredients | Phosphoric Acid, High Fructose Corn Syrup | Taurine, B-vitamins, Glucuronolactone | 
The Role of Other Ingredients
Beyond sugar, Coke and Red Bull have distinct nutritional profiles that affect the body differently.
Red Bull's Additional Stimulants Energy drinks like Red Bull are loaded with stimulants besides just sugar and caffeine. These often include taurine, B-vitamins, and other compounds intended to provide a prolonged 'energy boost'. The combination of a high-caffeine and high-sugar load can result in a more dramatic spike in energy, followed by a more significant crash. The effects of these added stimulants, especially in combination with high sugar and caffeine, are a serious health concern.
Caffeine Comparison Caffeine is another key difference. An 8.4-ounce Red Bull has approximately 80mg of caffeine, while a 12-ounce Coke has around 34mg. This means a standard Red Bull contains more than double the caffeine of a standard Coke, per serving, and nearly triple the caffeine concentration per ounce. This high caffeine content can lead to side effects like increased heart rate, anxiety, and sleep disruption.
Health Implications: High Sugar and Additives
Regardless of which beverage has slightly more sugar per ounce, both are considered sugar-sweetened beverages (SSBs) and are associated with a range of health issues when consumed excessively.
Health risks associated with SSBs:
- Weight Gain and Obesity: High sugar intake from SSBs contributes to excess calorie consumption, often leading to weight gain and obesity over time.
- Type 2 Diabetes: The constant spikes in blood sugar can strain the body's insulin response, increasing the risk of developing type 2 diabetes.
- Dental Issues: The combination of sugar and acidity in both drinks accelerates tooth decay and erodes enamel, causing cavities and gum disease.
- Cardiovascular Problems: Excessive consumption of sugary drinks is linked to an increased risk of heart disease and high blood pressure.
- Energy Crashes: The rapid spike in blood glucose from the simple sugars in Red Bull often leads to a subsequent energy crash, leaving you feeling more tired than before.
Are There Better Alternatives?
For those looking for a healthier alternative, both companies offer sugar-free and diet versions of their products. Red Bull offers 'Red Bull Sugarfree' and 'Red Bull Zero', and Coca-Cola has 'Diet Coke' and 'Coke Zero'. These alternatives use artificial sweeteners instead of sugar, eliminating the associated calories and sugar content. However, some health experts advise caution with artificial sweeteners as well. Alternatives like water, sparkling water with a splash of fruit, or unsweetened coffee and tea are healthier choices for hydration or a caffeine boost.

Conclusion: The Final Verdict
In a direct comparison of standard cans, a 12-ounce Coca-Cola contains more total sugar (39g) than an 8.4-ounce Red Bull (27g). However, when comparing the sugar concentration per fluid ounce, both drinks are virtually identical, containing approximately 3.2 grams of sugar per ounce. The total amount consumed ultimately depends on the serving size. More importantly, while Coke provides a sugar and caffeine dose, Red Bull includes additional stimulants that contribute to a different, and potentially more intense, physiological response. For overall health, both beverages should be consumed in moderation due to their high sugar content and associated health risks, with sugar-free alternatives being a slightly better option if you must choose.
How to make an informed choice
- Read nutritional labels carefully, paying attention to both serving size and total sugar grams.
- Calculate the sugar per fluid ounce for an accurate comparison of concentration.
- Be mindful of larger can sizes, which contain significantly more sugar and caffeine.
- Consider sugar-free alternatives if you are trying to reduce sugar intake.
- Prioritize water for hydration and consume sugary drinks as an infrequent treat.
