The Minimal Carb Content of Traditional Teas
For traditional teas derived from the Camellia sinensis plant, the brewing process involves steeping leaves, which infuses water with flavor and antioxidants while contributing almost no calories or carbohydrates. This applies to hot or iced preparations, as long as they remain unsweetened.
Black Tea
Black tea is the most oxidized type of traditional tea. A standard 8-ounce cup of plain, unsweetened black tea contains less than 1 gram of carbohydrates and around 2 calories. The carbohydrate content is so low that for most dietary purposes, it can be considered zero. This makes it a perfectly safe and satisfying beverage for those monitoring their carb intake or following a ketogenic diet. Its rich flavor comes from compounds called theaflavins and thearubigins, not sugars.
Green Tea
Green tea, which is not oxidized, is also virtually carb-free. When brewed, an 8-ounce cup contains no measurable carbohydrates, fat, or protein. Its potent health benefits are primarily attributed to antioxidant catechins, including EGCG, which are beneficial for weight management and overall health. This zero-carb profile makes unsweetened green tea a staple beverage for keto dieters.
White and Oolong Tea
Similarly, white tea (the least processed) and oolong tea (partially oxidized) contain trace or zero carbohydrates when brewed plain. The minimal processing of white tea preserves its delicate flavor and high antioxidant levels, while oolong's partial oxidation gives it a flavor profile between green and black tea. Both are excellent choices for low-carb lifestyles.
The Carb Content of Herbal Teas
Herbal teas, or tisanes, are infusions made from dried herbs, flowers, fruits, or spices. Their carbohydrate content depends entirely on their ingredients. While many are carb-free, others may contain trace amounts of natural sugars.
Here are some common examples:
- Chamomile and Peppermint: These are virtually carb-free and excellent choices for a low-carb diet.
- Hibiscus: This tea contains trace amounts of naturally occurring sugars, which result in a small but measurable carb count. One source indicates around 0.7 grams of carbohydrate in a medium-sized cup of unsweetened hibiscus tea.
- Blends with Dried Fruit: Herbal teas that include dried fruit pieces will naturally have higher carbohydrate and sugar content. Always check the ingredients list to be sure.
The Impact of Additives on Carb Count
While unsweetened tea itself is a safe bet for low-carb living, what you add to it can completely change its nutritional profile. For example, a chai latte can have over 30 grams of carbs due to milk and sweeteners, and bubble tea often exceeds 40 grams.
To keep your tea low-carb, consider these tips:
- Choose a Keto-Friendly Sweetener: Instead of sugar or honey, use calorie-free sweeteners like stevia or monk fruit extract.
- Opt for Low-Carb Milk Alternatives: Avoid regular cow's milk, which contains lactose, and instead use unsweetened almond or coconut milk.
- Add Natural Flavor: A squeeze of lemon or lime provides flavor with negligible carbs.
Comparison Table: Unsweetened Tea vs. Common Beverages
| Beverage | Carbohydrate Content (per cup) | Notes |
|---|---|---|
| Unsweetened Black Tea | 0–1g | Primarily water-based; negligible carbs. |
| Unsweetened Green Tea | ~0g | No measurable carbs or calories. |
| Unsweetened Herbal Tea | 0–2g | Varies by ingredients; check for dried fruit. |
| Black Coffee (plain) | ~0g | Similar to unsweetened tea, naturally carb-free. |
| Fruit Juice | 20–30g+ | High in natural sugars. |
| Sugary Soda | 35–45g+ | High in added sugars and empty calories. |
| Sweet Tea (bottled) | 20g+ | Can contain significant amounts of added sugar. |
| Milk Tea (with sugar) | 25g+ | High in carbs from both milk and sugar. |
Why Unsweetened Tea is a Great Choice
Beyond its near-zero carb count, unsweetened tea offers a host of other health benefits that make it an excellent dietary choice. The rich concentration of antioxidants, especially flavonoids and polyphenols, plays a protective role against various diseases, from cardiovascular issues to certain types of cancer. Regular consumption of unsweetened tea has also been linked to better hydration and metabolic health. Studies suggest that consistently drinking unsweetened tea, particularly 3.5 to 4.5 cups daily, is associated with a lower risk of all-cause mortality compared to drinking sweetened versions. Drinking plain tea can also contribute to weight loss by increasing calorie expenditure and preventing the high sugar intake linked to obesity and diabetes. For those on a ketogenic diet, unsweetened tea provides a much-needed beverage option that keeps them in a metabolic state of ketosis while providing hydration and healthy compounds. The simple act of choosing unsweetened tea over a sugary drink can make a significant difference in your daily carb and calorie intake.

Conclusion
In conclusion, the answer to the question, "Does unsweetened tea have carbs?" is a resounding no for most traditional brews like black, green, white, and oolong tea. For herbal teas, the presence of carbs is minimal and depends on the specific ingredients, but most pure infusions are also carb-free. This makes plain, unsweetened tea an ideal beverage for those managing their carb intake, whether for weight loss or a keto lifestyle. By avoiding high-carb additives and choosing pure tea, you can enjoy a delicious, hydrating, and health-promoting drink without compromising your dietary goals.
