Reading Labels on Sweetened Tea Products Is Easier Than You Think
The nutrition label on Arizona Diet Green Tea follows the same FDA template as everything else. One serving is eight ounces. The serving size line says eight fluid ounces, so if you drink a half-can that's technically two servings and doubles the numbers you're looking at. Most people don't do that math and just look at the per-serving column. It's fine, but it matters if you're tracking macros or sugar alcohols carefully. Here's what you'll find on the back of the can for one eight-ounce serving: zero calories, zero grams of sugar, zero grams of total fat, zero milligrams of sodium, zero grams of total carbohydrates, zero grams of protein. The ingredient list includes purified water, green tea extract, natural flavors, citric acid, and sucralose. Some batches also carry stevia leaf extract. There's about 25 to 30 milligrams of caffeine per eight-ounce serving depending on how you measure it. That's roughly half what you'd get from a standard cup of brewed black tea, which is relevant if you're sensitive to caffeine but trying to avoid sugar. The vitamins are where it gets interesting. Arizona puts in small amounts of vitamin C and B-complex vitamins. A single can gives you somewhere around 60 percent of the daily value for vitamin C and a modest bump of B6 and B12. These aren't there because the tea is a significant source of nutrients. They're added as fortification to justify the "diet" positioning and to make the label look less empty than a plain unsweetened green tea would.
I learned about the sucralose thing the hard way. A few years ago I was working with a client who had FODMAP sensitivity and was trying to avoid all artificial sweeteners. They picked Arizona Diet Green Tea because it says "zero sugar" on the front and assumed that meant it was clean. It's not. Sucralose is fine for most people, but it shows up in low-FODMAP databases as a non-approved additive for sensitive guts. The workaround was straightforward: I switched them to plain Arizona Pure Green Tea, which has no sweetener at all and no artificial ingredients. It tastes like weak steeped tea. You get used to it. The zero-sugar crowd usually doesn't, but it's the only real fix if you're dealing with gut issues and want to keep drinking canned tea. Another thing people miss is the citric acid. It's listed as an acidity regulator and flavor enhancer. It doesn't add carbs or calories, so it won't show up on the label at all. But if you have enamel sensitivity or acid reflux, the citric acid in this drink is noticeable. The pH is around 3.5 to 4, which is right in the danger zone for tooth erosion if you sip it slowly over an hour. Drinking it quickly or rinsing with water after is the standard mitigation. Not a big deal for most people, but worth knowing if you're already dealing with sensitive teeth. The caffeine content is another place where labels lie by omission. Arizona doesn't list caffeine on the Nutrition Facts panel. You have to go to the ingredient list or check their website. The 25 to 30 milligrams per can number comes from their own published data. If you're comparing this to other diet teas, keep in mind that "diet" on the label doesn't mean caffeine-free. It means sugar-free. The caffeine is still there, sometimes at higher levels than you'd expect from a green tea product. Matcha-based Arizona drinks push closer to 60 milligrams per can, which is a completely different conversation.
If you need exact numbers for a diet plan or meal tracking app, here's the breakdown per eight-ounce serving: calories zero, total fat zero grams, sodium zero milligrams, total carbohydrate zero grams, dietary fiber zero grams, total sugars zero grams, added sugars zero grams, protein zero grams, vitamin D zero micrograms, calcium zero milligrams, iron zero milligrams, potassium zero milligrams, vitamin C 4.8 milligrams or about 60 percent DV, thiamin 0.48 milligrams or 40 percent DV, riboflavin 0.44 milligrams or about 34 percent DV, niacin 4 milligrams or 25 percent DV, vitamin B6 0.48 milligrams or 28 percent DV, folate 20 micrograms or 5 percent DV, vitamin B12 0.24 micrograms or ten percent DV, and caffeine approximately 25 to 30 milligrams. The vitamins vary slightly by batch because fortification isn't locked to an exact number, it's locked to a range. The FDA requires a minimum nutrient level for a product to claim a vitamin source, and Arizona sits right above those thresholds. That's why the percentages aren't round numbers. It's not an error, it's just how supplement fortification works at this price point. One more practical note: if you're using this in a recipe or trying to match it to a macro target, don't assume the natural flavors contribute any measurable macronutrients. They don't. Natural flavor compounds are used at parts-per-million levels. The caloric contribution is effectively zero, and the carb count is not affected. The same goes for the stevia leaf extract in newer formulations. Stevia is non-caloric and doesn't register on the carb count either. The sucralose version tracks the same way. The only difference between the two formulations is the ingredient list and how your gut handles them.

I keep this information in a spreadsheet for clients who track everything. It took me about twenty minutes the first time to verify the numbers across multiple batches and update the sheet. Subsequent updates take maybe five minutes because the formula hasn't changed. Arizona doesn't reformat their labels often, which is the main reason this stays accurate without constant rechecking. If you want the official label, the most reliable source is the Arizona Beverage Company website. They post full nutrition PDFs for every product. Retailer sites like Walmart or Amazon often have outdated or incomplete images. The company PDF will show you the exact formulation including any recent stevia additions that some third-party listings haven't caught up to yet.
