It's no surprise that soda isn't good for your health. Drinking too many of these sugary, carbonated drinks on a regular basis can lead to numerous health complications that range from type 2 diabetes to obesity to heart disease—just to name a few. But gone are the days when the only healthy soda alternative was a boring glass of water (or sparkling water). These days, there are plenty of diet sodas out there that can satisfy your soda cravings with low-sugar options that taste like the real thing. The only problem now is that there are so many to choose from that you may not know what the best diet soda brands are.

For those looking to savor the refreshing fizz of a soda without the guilt of excess sugar or calories, we spoke to registered dietitians to uncover the top diet soda contenders that not only satisfy your taste buds but also align with your health goals. Whether you want to reduce added sugar intake, cut calories, or simply find a refreshing, bubbly beverage, our expert recommendations will help you make an informed choice on your next grocery store run.

How we selected the best diet sodas

  • Taste: Diet sodas notoriously have a bad reputation for their aftertaste from artificial sweeteners.
  • Added sugar: One of the main health reasons for choosing diet soda in the first place is the low sugar content! Diet sodas these days are sweetened with everything from stevia and monk fruit to Splenda to aspartame. While they all are sugar-free options, you might find that you prefer one over the other. Artificial sweeteners are safe in small doses, such as the amount in one diet soda. However, if you're drinking several per day or using them to blunt your appetite instead of eating, you might want to pare it back.
  • Sodium: Traditional diet sodas do contain sodium and depending on how many you plan on drinking in a day, this added salt can add up quickly!
  • Personal preference: You might find that you don't mind the taste of stevia at all, but sucralose is overpowering for you, for example. Everyone has their own unique preferences when it comes to diet soda. That's why we are sharing both traditional diet and modern "healthified" sodas—and why we like them both for different reasons!

Per can: 35 calories, 0 g fat (0 g saturated fat), 25 mg sodium, 16 g carbs (9 g fiber, 2 g sugar), 0 g protein

OLIPOP's Vintage Cola offers the taste of regular soda with a twist—it only contains 2 grams of added sugars and a whopping 9 grams of prebiotic fiber.

"If you're looking for a soda alternative, I'd recommend a functional soda like OLIPOP that combines the classic soda taste with the benefits of plant-based fiber, prebiotics, and other botanical ingredients to help support gut health," says Melissa Boufounos, CHN, sports nutritionist and owner of MB Performance Nutrition.

While traditional soda is loaded with sugar and additives, each can of OLIPOP has 35-45 calories, contains 2 to 5 grams of natural sugars, and provides a whopping 9 grams of prebiotic plant fiber, which is 32% of the Daily Value for fiber, Boujounos adds.

Sweetened with organic agave, MAYAWELL is a low-calorie beverage option that also doubles as a gut-friendly prebiotic soda. With fruity flavors like raspberry, strawberry ginger, and pineapple, we love that each can has less than 40 calories, 4 grams of added sugar, and 5 grams of fiber. If you are not a fan of artificial aftertaste, you would likely love this product as the only sweetener it uses is agave nectar—no artificial or non-nutritive sweeteners here!

Free from artificial sweeteners and their aftertaste which is an aversion for some, many people find that Zevia is a great alternative that doesn't taste like diet drinks. This product does contain 45 milligrams of caffeine, so keep that in mind if you are sensitive to caffeine late in the day.

Chrissy Barth, RD shares why she loves Zevia: "It comes in a variety of flavors, contains zero sugar, is naturally sweetened with stevia, and tastes great!"
