Both vodka and tequila are distilled spirits, which means they contain ethanol and water, but little else of nutritional significance in their purest form. When you compare them directly, the differences are minimal, and the ultimate impact on your health depends heavily on serving size, consumption frequency, and what you mix them with.
The Calorie and Carb Breakdown
For most drinkers, the primary concern is calories. The good news is that, when comparing 80-proof (40% ABV) versions, the calorie count is nearly identical for a standard 1.5-ounce shot.
- Vodka: Approximately 97 calories per 1.5 oz.
- Tequila: Approximately 97 calories per 1.5 oz.
Additionally, both spirits contain zero carbohydrates, fat, or protein when consumed neat. The moment you add mixers like soda, juice, or syrups, the caloric and sugar content can skyrocket. For instance, a vodka tonic with standard tonic water will have more calories than a simple vodka with soda water. A margarita with sugary mix is far more calorie-dense than a shot of 100% agave tequila.
Ingredient Origins: Agave vs. Grain
Beyond the basic nutritional profile, the two spirits differ in their origin, which some argue gives tequila a slight edge, though research is limited and benefits likely minimal.
Vodka's Neutrality
Vodka is a neutral spirit typically made from fermented grains like wheat, rye, or corn, or from potatoes. Its production is designed to create a product that is as odorless and flavorless as possible. This makes it a blank canvas for cocktails but also means it contains no notable vitamins or minerals.
Tequila's Agave Advantages
Tequila is made exclusively from the blue agave plant in Mexico. The agave plant contains fructans, which are a type of prebiotic fiber. Some studies suggest fructans may support gut health by promoting beneficial bacteria and could potentially aid in weight management by affecting satiety hormones. However, the distillation process may remove or significantly reduce these compounds, so it's unclear how much of this benefit carries over to the final product. High-quality, 100% agave tequila may also retain trace minerals like potassium and magnesium, but not in significant dietary amounts.
The Mixers: The Real Calorie Culprit
For both vodka and tequila, the mixers make the biggest nutritional difference. To keep your drinks as healthy as possible, opt for low-calorie options.
- Healthier Mixers for Vodka: Club soda, sparkling water, fresh lemon or lime juice, or a splash of cranberry juice (check for added sugar). Flavored vodkas can also reduce the need for sugary additions.
- Healthier Mixers for Tequila: Fresh lime juice and a little soda water for a lighter 'skinny' margarita.
The Congener Factor: Hangovers
Congeners are toxic compounds produced during fermentation that can contribute to the severity of hangovers. Generally, clear spirits like vodka and 100% agave tequila have fewer congeners than darker spirits like whiskey or aged rum.
- Vodka: Known for having very few congeners due to its heavy distillation and filtration.
- Tequila: 100% agave tequila is also relatively low in congeners, which may result in less severe hangovers compared to some other spirits.
Vodka vs. Tequila: A Nutritional Comparison
| Feature | Vodka | Tequila (100% Agave) |
|---|---|---|
| Calories (1.5 oz) | ~97 | ~97 |
| Carbohydrates | 0g (neat) | 0g (neat) |
| Fat | 0g | 0g |
| Sugar | 0g (neat) | 0g (neat) |
| Origin | Grains or Potatoes | Blue Agave Plant |
| Unique Properties | Neutral flavor, no congeners | Prebiotic fructans (potentially reduced) |
| Best Health Choice | Depends on mixer | Depends on mixer |
The Healthiest Option is Moderation
Ultimately, neither vodka nor tequila is inherently "healthy." They are both alcoholic beverages that should be consumed in moderation. Excessive alcohol intake is linked to a variety of serious health issues, including liver disease, heart problems, certain cancers, and mental health conditions. The healthiest choice is to limit alcohol consumption or abstain altogether. For those who choose to drink, making conscious choices about mixers and practicing moderation is the key to minimizing negative health impacts.

Conclusion
When a friend asks, which is healthier, vodka or tequila?, you can confidently tell them that from a basic nutritional standpoint, they are virtually identical. The real nutritional battle is won or lost by what you mix with your spirit. For the health-conscious consumer, the best strategy is to opt for low-sugar mixers, control portion sizes, and always drink responsibly. The minimal differences between the two spirits pale in comparison to the dietary impact of sugary sodas, juices, and cocktail syrups.
