Nutritional Comparison: Seltzers vs. Beer

Calorie content

Counting calories is a crucial part of many weight management plans, and the choice between seltzers and beer can greatly impact your daily intake. Seltzers typically edge out beer in this category, offering fewer calories per serving.

For instance, hard seltzer contains about 100 calories per portion while an average beer holds approximately 153 calories. Notably, these are averages – specific brands may vary significantly based on ingredients and alcohol volume.

Choosing a hard seltzer over beer could indeed save you a few dozen calorie count each time you indulge, which adds up if alcoholic beverages are a regular part of your routine.

Carbohydrate content

In general, seltzers have a lower carbohydrate content compared to most beers.

Hard seltzers are made with flavored carbonated water, which typically contains zero carbohydrates.

On the other hand, regular beer can contain varying amounts of carbohydrates depending on the style and brand. Light beers tend to have fewer carbs than traditional beers, but they still generally contain more carbs than hard seltzers.

So if you’re watching your carb intake or following a low-carb diet, opting for a hard seltzer may be a better choice for you in terms of carbohydrate content.

Alcohol content

Hard seltzers typically have a lower alcohol content compared to beer, making them a lighter option for those who are looking to moderate their alcohol intake. While the alcohol content in beer can vary depending on the brand and type, it generally ranges from 4% to 6%, or even higher in craft beers.

On the other hand, most hard seltzers contain around 5% alcohol by volume. This means that drinking hard seltzers may result in consuming less alcohol per serving compared to beer.

Gluten content

Hard seltzers are often promoted as a gluten-free alternative to beer. While it’s true that most hard seltzers do not contain gluten, not all of them are completely gluten-free. Some hard seltzers may be produced in facilities where cross-contamination with gluten-containing grains can occur.

Therefore, if you have celiac disease or a strong sensitivity to gluten, it is essential to check the labels and choose brands that explicitly state they are gluten-free.

Additionally, it’s important to note that while avoiding gluten can be beneficial for those with specific dietary needs, it does not necessarily make hard seltzers a healthier choice overall.

Health Considerations of Seltzers and Beer

Proper hydration is essential for overall health, and it’s important to consider this when choosing between seltzers and beer. While both beverages can contribute to fluid intake, seltzers may have an advantage in terms of hydrating the body.

This is because seltzers are typically made with carbonated water, which can help quench thirst more effectively than regular water alone.

Seltzers also tend to be lighter in alcohol content compared to beer, which means they may have less diuretic effect on the body. Alcohol has a dehydrating effect as it increases urine production, potentially causing dehydration if not balanced with adequate fluid intake.

By opting for lower-alcohol seltzer options, individuals can enjoy their drink without compromising proper hydration.

Impact on blood sugar levels

Hard seltzers have gained popularity as a lower-calorie alternative to beer, but when it comes to their impact on blood sugar levels, there are some important considerations. While hard seltzers generally contain less sugar than traditional beers, they still contain alcohol, which can affect blood sugar control.

Consuming alcohol can lead to temporary spikes in blood glucose levels and make it harder for the body to regulate insulin production. This is especially important for individuals with diabetes or other metabolic conditions.

Making Healthier Choices: Factors to Consider

Personal dietary goals

Whether you are trying to lose weight, maintain a balanced diet, or reduce your sugar intake, understanding how different beverages align with your objectives is crucial.

For individuals looking for low-calorie options, spiked seltzers can be a better choice compared to beer as they generally contain fewer calories and carbs.

By incorporating personal dietary goals into your decision-making process, you can make more carb-conscious choices and find alternatives that align with your health-focused lifestyle.

Portion control

Here are some key points to keep in mind:

  • Keep track of the number of servings consumed: Monitoring the number of seltzers or beers consumed helps maintain control over alcohol intake.
  • Be mindful of serving sizes: Seltzers and beers come in varying container sizes, such as bottles and cans. Opting for smaller serving sizes can help reduce caloric intake.
  • Choose lower alcohol content options: Some seltzer brands offer lower alcohol content compared to traditional beers. Selecting these options can aid in managing alcohol consumption while still enjoying a refreshing beverage.
  • Pay attention to mixers and additives: If mixing seltzers or beer with other ingredients, be mindful of added sugars and calories from mixers like fruit juices or syrups. Opt for low-sugar or sugar-free alternatives when possible.
  • Consider non-alcoholic or low-alcohol alternatives: For individuals prioritizing sobriety or aiming to reduce their alcohol intake, non-alcoholic seltzers or low-alcohol beers can provide satisfying alternatives with fewer calories.

Ingredients and additives

Hard seltzers typically contain simple ingredients like carbonated water, alcohol, and natural flavorings.

They often have fewer artificial additives compared to some beers that may include preservatives or sweeteners. This can make seltzers a more appealing option for those looking to avoid unnecessary chemicals in their drinks.

However, it’s still crucial to read labels and choose brands that prioritize natural ingredients if you’re concerned about additives in your alcoholic beverages.

When it comes to beer, the ingredient list tends to be longer and includes things like malted barley, hops, yeast, and additional flavorings. While these ingredients aren’t necessarily harmful or unhealthy on their own, they do contribute more calories and carbohydrates compared to hard seltzers.

Some specialty craft beers may even contain higher alcohol content or added sugars for extra flavor. So if you’re watching your caloric intake or trying to reduce carbs while enjoying a drink, opting for a spiked seltzer might be a better choice than certain types of beer.

By being mindful of the ingredients and additives in both seltzers and beer, you can make more informed decisions about which beverage aligns with your dietary goals without compromising on taste or enjoyment.


In conclusion, while seltzers may have certain advantages over beer in terms of lower calorie and carbohydrate content, it is important to remember that they are still alcoholic beverages.

Ultimately, choosing between seltzers and beer depends on personal dietary goals, portion control, and individual preferences.
