FAQ

Which diet soda is the healthiest?

As much as we wish things were different, diet sodas aren’t health foods. Labeling them as ‘healthy’ is a misnomer. Calorie-free sodas are an occasional tasty indulgence to be enjoyed in small amounts with great gusto. Here are a few things to consider when making your choice.

• Aspartame. While there has been no definitive link between aspartame and ill-health – the FDA insists that it’s safe – it’s still wise to limit the amount you consume. Look for diet sodas that use alternatives, like Stevia or actual fruit juice to sweeten their product.

• Acids. A tasty soda has got bite. While that may be an excellent thing taste-wise, it's not great for your teeth. Soft drinks contain citric, malic, and phosphoric acids, adding tartness to beverages. These additives leach calcium from your teeth and is linked to tooth decay.

• Caffeine. Many people look to soda, particularly cola, to boost their energy. And once in a while, that’s fine. Popular diet soda options offer 35-46 mg of caffeine, which is a little more than 10% of the FDA’s daily limit of 400 mg. But if you’re having trouble sleeping, you might want to restrict your intake or find a brand with a lower amount of caffeine per serving. 

What soda is best for weight loss?

Diet sodas aren’t a magic bullet when it comes to weight loss. As with any food, moderation’s key. You don’t want to rely exclusively on one food group to mitigate unhealthy choices in other areas of your diet. 

Diet drinks are low in sugar and perfect for people looking to reduce their carb intake: people with diabetes or on a ketogenic diet. For these people, occasionally indulging in a can of diet soda isn’t going to have a huge negative impact. If you’re looking to make a slightly healthier beverage choice or looking for the best diet soda for keto diets, choose a brand that uses Stevia, monk fruit, sucralose, or sugar alcohols such as Xylitol or erythritol as a sweetener.

Flavored sparkling water or carbonated water might also satisfy your soda craving without the added sugars or sugar substitutes.

People looking to reduce the risk of heart disease should avoid drinking diet soda as a general rule. Researchers have discovered that people who regularly drink artificially sweetened beverages have an increased heart and stroke risk.

Your best bet is to speak with a registered dietitian to learn whether diet sodas are right for you. 

What diet soda has no aspartame?

At one time, the only sweetening option for diet versions of popular sodas that manufacturers had available was aspartame. The result was a product that closely resembled the flavor of the original. As a matter of fact, the best diet sodas that taste like regular versions often include aspartame. 

If you’re looking for aspartame-free sodas, you do have options. Zevia offers an entire line of soft drinks sweetened with Stevia, a popular alternative to artificial sweeteners, including their crowd-pleasing Diet Ginger Root Beer flavor. Newcomer Poppi also provides a line of sodas sweetened with a combination of fruit juices and Stevia in various flavors like strawberry lemon or watermelon that make for a delicious alternative to aspartame.
