Comparing the Sugar Content: Coke vs. Iced Tea
When evaluating the sugar content of Coca-Cola and iced tea, the most important factor for iced tea is whether it is sweetened or unsweetened, and if sweetened, how heavily. Coca-Cola's recipe is standardized, but the sugar in iced tea can vary dramatically. This variability is what often leads to confusion, as a heavily sweetened commercial iced tea can sometimes contain as much, or even more, sugar than a can of Coke.
The Standard for Coke
A standard 12-ounce (355ml) can of Coca-Cola Classic typically contains 39 grams of sugar. This equates to roughly 9 to 10 teaspoons of sugar, a substantial amount that often surpasses the daily recommended sugar intake in a single serving. All of this sugar is added, providing no nutritional benefits beyond energy.
The Iced Tea Spectrum
Unlike Coke, the term “iced tea” is not a single product but a category with vast differences. At one end, unsweetened home-brewed iced tea contains virtually no sugar. At the other end, some heavily sweetened commercial iced teas can rival soda in sugar density.
Here are the common variations:
- Unsweetened Home-Brewed Iced Tea: The healthiest option, containing zero grams of sugar. The consumer has full control over any additions.
- Restaurant-Prepared Sweet Tea: Often a major source of hidden sugars, especially in the Southern United States. Some sweet teas can be made with so much sugar that they exceed the concentration found in Coca-Cola, with sugar levels that can be twice that of Coke's standard concentration.
- Bottled and Canned Iced Tea: Popular brands vary, but many contain significant amounts of added sugar. For instance, some brands may contain around 20-30 grams of sugar per 16-ounce serving, which is less than a can of Coke but still a high amount. However, some other brands in larger 20-ounce bottles can have as much as 60 grams of sugar, putting them on par with, or even exceeding, a 20-ounce bottle of soda.
Health Implications of High Sugar Intake
Consuming high levels of sugar from beverages like Coke or heavily sweetened iced tea is linked to several negative health outcomes, including:
- Weight gain and obesity
- Increased risk of type 2 diabetes
- Higher risk of heart disease
- Dental caries (tooth decay)
Switching to unsweetened iced tea is an easy way to reduce these health risks while still enjoying a flavorful and refreshing beverage.
Comparison Table: Coke vs. Iced Tea Sugar Content
| Beverage Type | Serving Size | Approximate Sugar (grams) | Notes |
|---|---|---|---|
| Coca-Cola Classic | 12 oz (355ml) | 39g | High, added sugar content |
| Unsweetened Iced Tea (Homemade) | 12 oz (355ml) | 0g | No added sugar |
| Bottled Iced Tea (e.g., Lipton Iced Tea) | 16 oz (473ml) | ~25-30g | Contains added sugar, varies by brand |
| Arizona Iced Tea | 24 oz (710ml) | 55g | Very high sugar content, comparable to soda |
| Restaurant Sweet Tea (Southern-style) | 16 oz (473ml) | ~30-40g+ | Often very high, can exceed Coke |
Nutritional Context
Beyond sugar, Coke and iced tea offer different nutritional profiles. Coke provides empty calories and caffeine but no other redeeming nutritional value. Tea, on the other hand, contains antioxidants and can offer potential health benefits, especially when consumed unsweetened. The antioxidants in green and black tea may help protect the body against free radicals and support cardiovascular and metabolic health. This is a crucial distinction, as even a sweetened iced tea still retains some of these benefits, unlike soda.
Conclusion: The Choice is Yours
Ultimately, deciding whether Coke or iced tea has more sugar is about understanding the specifics of the iced tea in question. While unsweetened iced tea is the clear winner for low sugar content, a commercially prepared, pre-sweetened iced tea can contain comparable levels of sugar to Coke. For those seeking a healthier beverage, brewing your own tea and controlling the sweetener is the most reliable option. If choosing a pre-made beverage, it's essential to check the label carefully, as marketing can be misleading. The health-conscious choice is always to opt for the unsweetened version to enjoy the natural benefits of tea without the detrimental effects of excessive sugar.

Frequently Asked Questions
What is the healthiest iced tea to drink?
The healthiest iced tea is unsweetened, home-brewed tea. This version contains zero sugar and retains all the antioxidants and health benefits of the tea leaves.
Do all bottled iced teas have high sugar?
No, many brands offer unsweetened or diet versions with zero calories and zero sugar. However, the standard, sweetened varieties often contain significant amounts of added sugar, so it is important to read the nutritional label carefully.
Can commercial iced tea have more sugar than Coke?
Yes, some commercial iced teas, particularly large bottles of heavily sweetened brands, can contain as much or even more sugar than a similar-sized serving of Coke. For example, some large bottled iced teas contain up to 60 grams of sugar.
What type of sugar is in Coke?
Coca-Cola is sweetened with high-fructose corn syrup in the United States, and sucrose (table sugar) in many other countries. It is all added sugar and provides no nutritional value.
Is homemade sweet tea better than Coke?
Homemade sweet tea can be healthier than Coke because you control the amount of sugar added. By using less sugar, you can reduce the overall sugar content significantly. It also contains natural antioxidants from the tea leaves, which Coke does not.
How can I reduce my sugar intake from beverages?
To reduce sugar from beverages, opt for unsweetened options like water, plain iced tea, or sparkling water with a splash of fruit juice. If you enjoy a sweeter taste, use natural, low-calorie sweeteners in moderation.
Does the type of tea (black vs. green) affect the sugar content?
The type of tea leaf (black, green, etc.) does not inherently affect the sugar content. The sugar is added separately. The main difference lies in the flavor profile and antioxidant compounds found in the leaves.
