Yogurt has long been a staple in healthy diets, but the modern grocery store aisle can be overwhelming with countless options. From traditional and Greek to Icelandic skyr and plant-based alternatives, understanding the nutritional differences is key to choosing the healthiest option for your body.
The Three Key Indicators of a Healthy Yogurt
When comparing different yogurts, prioritize three main factors to find a truly healthy product:
- Low Added Sugar: The biggest pitfall in yogurt is the excessive amount of added sugar, especially in flavored varieties. Always check the nutrition label for the "Added Sugars" line and aim for products with minimal to zero grams. Sweetening plain yogurt yourself with fresh fruit or a touch of honey gives you full control over the sugar content. Naturally occurring sugar (lactose) is acceptable, and the new nutrition labels help distinguish between natural and added sugars.
- High Protein Content: Protein promotes satiety, helping you feel full and satisfied for longer, which can assist with weight management. Greek and Icelandic yogurts are particularly high in protein due to their straining process. A good yogurt should have at least 10 grams of protein per serving.
- Live and Active Cultures: These are the beneficial probiotics that support digestive health and a balanced gut microbiome. Look for the "Live & Active Cultures" seal from the National Yogurt Association to ensure the product contains a minimum level of these bacteria at the time of manufacture. Heat-treated yogurts, like some drinkable varieties, may not contain active cultures.
Comparing Popular Yogurt Types
Choosing the right yogurt depends on your specific health goals and dietary needs. Here is a breakdown of the most common types.
Greek Yogurt
Greek yogurt is made by straining regular yogurt to remove the liquid whey, resulting in a much thicker, creamier product. It is celebrated for its high protein content, often double that of traditional yogurt, and lower lactose levels, which can be beneficial for those with mild lactose intolerance. Plain, unsweetened Greek yogurt is an excellent, versatile choice for a balanced diet.
Icelandic Skyr
Skyr is a traditional Icelandic cultured dairy product that is strained even more than Greek yogurt, giving it an extra-thick, dense texture. It is exceptionally high in protein and naturally fat-free in its traditional form. This makes it a great option for people seeking maximum protein intake and a low-fat profile.
Regular/Traditional Yogurt
This is the unstrained version, which has a thinner consistency, less protein, and higher calcium than strained varieties. While lower in protein, plain traditional yogurt is still a very healthy option, provided it has no added sugar. It's often more affordable than Greek or Icelandic varieties.
Plant-Based Yogurts
For vegans or those with dairy allergies, plant-based yogurts offer an alternative. Soy-based yogurts are typically the most nutritionally similar to dairy yogurt, especially when fortified with calcium and vitamin D. Other alternatives like coconut or almond milk yogurts can be healthy, but often contain less protein and may have higher saturated fat, so checking the label for fortification and additives is crucial.
The Importance of Plain Yogurt
While flavored yogurts are tempting, plain, unsweetened versions are almost always the healthiest choice. This gives you complete control over your sugar intake. Many flavored yogurts can pack in more sugar than a dessert. By choosing plain yogurt, you can sweeten it naturally and add extra nutrients yourself.
Here are some healthy topping ideas for plain yogurt:
- Fresh or frozen berries for natural sweetness and antioxidants.
- A sprinkle of cinnamon or vanilla extract for added flavor without sugar.
- A small drizzle of honey or maple syrup for controlled sweetness.
- Chopped nuts or seeds (like chia or flax) for healthy fats and fiber.
- Granola (with low added sugar) for a satisfying crunch.
Nutritional Comparison Table
| Feature | Greek Yogurt | Icelandic Skyr | Regular Yogurt | Plant-Based Yogurt (e.g., Soy) |
|---|---|---|---|---|
| Protein | High (concentrated) | Very High (most concentrated) | Moderate (unconcentrated) | Varies (check label; often lower) |
| Texture | Thick and creamy | Extra thick and dense | Thinner, more liquid-like | Varies (often thinner) |
| Lactose | Lower (strained) | Very low (extra strained) | Higher (unstrained) | None (lactose-free) |
| Calcium | Often lower than regular yogurt | Lower than regular yogurt | Higher (unstrained) | Varies (look for fortification) |
| Gut Health | Contains probiotics | Contains probiotics | Contains probiotics | Varies (check for live cultures) |
How to Select the Best Yogurt for You
- Prioritize the Plain Option: Whenever possible, opt for plain, unsweetened yogurt to avoid unnecessary added sugars and additives. This is the single most important rule for choosing the healthiest yogurt.
- Read the Label Carefully: Don't be fooled by packaging. Check the ingredients list for a short, simple list. Prioritize products where sugar is not listed as one of the first few ingredients.
- Consider Your Protein Needs: If you're looking for a post-workout snack or want to increase satiety, Greek or Icelandic skyr is likely the best choice.
- Check for Live Cultures: Ensure the product contains live and active cultures to receive the probiotic benefits for your gut health.
- Evaluate Fat Content: The debate over low-fat vs. full-fat continues. Full-fat versions can be more satisfying, while low-fat options may be better for those monitoring their saturated fat intake. Ultimately, the best choice depends on your personal health goals and dietary requirements.
The Power of Probiotics and Gut Health
Beyond macronutrients, the live cultures found in yogurt offer significant health benefits, primarily by supporting a healthy gut microbiome. A balanced gut can influence everything from digestion and immunity to mood and weight management. The fermentation process of yogurt creates these beneficial bacteria, which help with digestion and nutrient absorption. However, not all yogurts contain sufficient live cultures, especially those that have been heat-treated after fermentation. For maximum probiotic benefit, look for products with the "Live & Active Cultures" seal and choose a fresher product, as probiotic levels decrease over time. For example, kefir, a drinkable fermented milk, often contains an even wider variety of probiotic strains than yogurt.
Conclusion
While many yogurts offer health benefits, the healthiest option for most people is plain, unsweetened Greek or Icelandic skyr due to their high protein and low sugar content. By taking a few moments to read the nutrition label and understanding the simple rules of low sugar, high protein, and active cultures, you can navigate the yogurt aisle with confidence and make a delicious, healthy choice for your next snack or meal.
The Takeaway: Choosing the Healthiest Yogurt
For maximum protein and minimal sugar, opt for plain Greek or Icelandic skyr. The most important thing is to choose an unsweetened variety to avoid excess sugar and add your own natural flavors. Always check the label for live and active cultures for gut health benefits.
Homemade Yogurt: A Simple & Healthy Alternative
For those who want complete control over their ingredients, making yogurt at home is a simple and rewarding process. A homemade yogurt allows you to eliminate all additives and control the fat, sugar, and bacterial culture. You can easily find recipes that use just milk and a starter culture, which can be a prior batch of high-quality yogurt or a freeze-dried starter. Fermenting for longer periods can reduce the lactose content further, making it even more digestible. A homemade approach ensures the freshest, most active cultures for optimal gut health.

Navigating the Dairy Aisle
By following these guidelines, you can make an informed choice that aligns with your health goals. Whether you prioritize protein, gut health, or simply avoiding added sugar, the perfect yogurt is waiting for you.
Is All Plain Yogurt the Same?
No, even plain yogurts differ in nutritional profile based on the milk used (non-fat, low-fat, or whole), and whether it has been strained. Check the protein and fat content on the label.
What About Kefir?
Kefir is a drinkable, fermented milk product that often contains a wider variety of probiotic strains than yogurt. This makes it an excellent choice for targeted gut health benefits. As with yogurt, opt for plain versions to avoid added sugars.
Are Additives in Yogurt Harmful?
Unhealthy additives like excessive sugar, artificial flavors, and stabilizers should be avoided. While some additives are harmless, an elaborate ingredient list is often a red flag for a less-than-healthy product. The simplest ingredient list is usually the best.
