Understanding Sugar in Yogurt: Natural vs. Added
When selecting yogurt, it's crucial to understand the two main types of sugar you will encounter: naturally occurring sugar (lactose) and added sugars. Plain, unflavored yogurts contain only natural lactose, typically ranging from 4 to 12 grams per serving, depending on the type and brand. Added sugars, however, are sweeteners manufacturers add to enhance the taste, and these can significantly increase a yogurt's sugar count. This is especially common in fruit-on-the-bottom or dessert-flavored varieties, which can contain a surprising amount of extra sugar. The key to finding the lowest-sugar option is to choose plain yogurt or a product explicitly made with zero or minimal added sugar.
The Lowest-Sugar Options: Plain Greek and Skyr
For the absolute minimum sugar content, plain, unsweetened varieties are your best bet. Among these, Greek and Icelandic yogurts (skyr) are consistently the lowest in sugar. The reason lies in their straining process, which removes excess whey, concentrating the protein and reducing lactose (milk sugar). This results in a much thicker, higher-protein yogurt with significantly less sugar per serving compared to traditional yogurt.
- Plain Greek Yogurt: Brands like Fage Total 0% Plain Greek Yogurt contain only 5 to 7 grams of naturally occurring sugars per 5.3-ounce cup, with zero grams of added sugar. This makes it a great, protein-rich canvas for your own low-sugar additions.
- Plain Icelandic Skyr: Similar to Greek yogurt, skyr is a strained product known for its thick texture and high protein content. Siggi's Plain Icelandic Yogurt, for instance, contains just 4 grams of natural sugar and no added sugar. Icelandic Provisions Plain Skyr also contains zero added sugar.
Low and Zero-Sugar Flavored Alternatives
If plain yogurt is too tart for your taste, several brands offer flavored varieties with minimal or zero added sugar by using alternative sweeteners like stevia, monk fruit, and allulose. These yogurts provide a sweeter experience without the added sugar and extra calories.
- Chobani Zero Sugar: This line of Greek yogurt is naturally fermented to remove lactose and is sweetened with natural, non-GMO alternatives like monk fruit. It boasts 0g total sugar per serving.
- Oikos Triple Zero: This nonfat Greek yogurt lives up to its name with 0 added sugar, 0 artificial sweeteners, and 0% fat. It provides 15 grams of protein per 5.3-ounce cup.
- Too Good & Co. Blended: Offering low sugar at just 2 grams per cup, this yogurt uses stevia to achieve its slightly sweet flavor while providing 12 grams of protein.
How to Decipher Nutrition Labels for Sugar Content
Reading the nutrition label is your most powerful tool for making an informed decision. The amount listed under 'Sugars' includes both naturally occurring lactose and added sugars. To determine the added sugar, you have to look deeper at the ingredients list, or for newer labels, the 'Added Sugars' line.
- Check the ingredients list: Ingredients are listed by weight. If a form of sugar is one of the first few ingredients, the yogurt likely has a high amount of added sugar. Be aware of different sugar names, such as cane sugar, high fructose corn syrup, fruit juice concentrate, fructose, glucose, and syrup.
- Calculate the added sugar: On older labels, you can roughly estimate added sugar by subtracting the naturally occurring sugar (around 5-7g for plain Greek yogurt) from the total sugar count. For a 5.3 oz serving, if the total sugar is 16 grams and the natural sugar is 6 grams, you have consumed 10 grams of added sugar. On newer labels, the added sugars are listed separately.
Create Your Own Low-Sugar Yogurt Creations
Choosing a plain, unsweetened yogurt and adding your own toppings gives you complete control over the sugar content. This also offers creative freedom to customize flavors and textures.
Ideas for naturally sweetening yogurt:
- Fresh Fruit: Add a handful of berries, sliced banana, or diced mango. Fruit provides natural sweetness along with fiber and vitamins.
- A Drizzle of Honey or Maple Syrup: A small amount of natural sweetener can go a long way. Use it sparingly to control the sugar content.
- Spices: Cinnamon, nutmeg, and vanilla extract can enhance the flavor without adding any sugar.
- Nuts and Seeds: Toasted nuts, chia seeds, or ground flax seeds add texture, healthy fats, and fiber, helping you feel fuller longer.
Comparison Table: Low vs. High-Sugar Yogurts
To illustrate the difference, here is a comparison of typical low-sugar and high-sugar yogurt products. Data is based on 5.3-ounce (150g) servings, where applicable.
| Feature | Low-Sugar Plain Greek/Skyr (e.g., Fage Total 0%, Siggi's Plain) | Zero-Sugar Flavored (e.g., Chobani Zero Sugar, Oikos Triple Zero) | High-Sugar Flavored (e.g., Fruit-on-the-bottom) |
|---|---|---|---|
| Total Sugars (g) | ~5-7g (natural lactose only) | 0-7g (natural lactose, some artificial sweeteners) | >15g (natural + added sugars) |
| Added Sugars (g) | 0g | 0g | Significant amount |
| Protein (g) | 15-16g | 11-15g | Varies, typically less than plain Greek |
| Best For | Maximum control over sugar content; versatile for sweet or savory dishes | Convenience of pre-flavored option with no added sugar | Occasional treat, less ideal for daily intake due to added sugar |
Conclusion: Making the Right Choice
Choosing a yogurt with the least amount of sugar doesn't mean sacrificing flavor or enjoyment. By opting for plain Greek or Icelandic yogurt, or selecting a zero-added-sugar flavored brand, you can significantly reduce your sugar intake while still benefiting from yogurt's high protein and probiotic content. Learning to read nutrition labels is the most effective way to make smart, healthy decisions that align with your dietary goals. Starting with a plain yogurt and adding your own fruits and spices is the most reliable way to maintain control and ensure a truly low-sugar snack.

Making Yogurt at Home
For those who want complete control over their yogurt's ingredients, making your own at home is a simple process. It guarantees a product free from added sugars and unnecessary additives.
Ingredients
- Milk (whole or skim)
- Live active yogurt cultures (either a starter culture or a few tablespoons of plain, unflavored yogurt with live cultures)
Instructions
- Heat milk to approximately 180°F to kill any bacteria.
- Let the milk cool to around 110°F.
- Stir in the starter culture.
- Pour the mixture into a jar or container and keep it warm for several hours to allow it to ferment.
- Once the yogurt has reached your desired thickness and tanginess, refrigerate it to halt the fermentation process.
For a thicker, Greek-style yogurt, simply strain the finished product through cheesecloth to remove some of the whey.
