Understanding the Sugar in Plain Greek Yogurt
Unlike its flavored counterparts, plain Greek yogurt does not contain added sugars. The sugar you see on the nutritional label is naturally occurring lactose, the sugar found in milk. The key difference lies in the production process. Greek yogurt is strained multiple times to remove the liquid whey, which also removes much of the lactose. This straining process results in a thicker, tangier product with a higher protein concentration and lower sugar content compared to regular yogurt.
The Nutritional Label Breakdown
When examining the nutritional label, it's crucial to understand the difference between naturally occurring and added sugars. While current regulations may not separate these on all labels, the ingredient list is your best friend. For plain Greek yogurt, you will not find any form of added sweetener in the ingredients list, such as cane sugar, high-fructose corn syrup, or fruit concentrates. The total sugar count, typically between 6 to 9 grams per 5.3-ounce serving, comes entirely from lactose. This is significantly less than flavored yogurts, which can contain 15 grams or more of added sugar.
Plain Greek Yogurt vs. Flavored Yogurt
Plain Greek yogurt is the ideal base for a healthy snack because it gives you control over the amount and type of sugar you consume. By adding your own fresh fruit, a small amount of honey, or natural spices like cinnamon, you can enjoy a flavorful treat without the excessive, often-hidden sugars found in pre-mixed products. In fact, some studies show people often add less sugar to plain yogurt themselves than what is found in many sweetened versions.
How Plain Greek Yogurt Affects Blood Sugar
Because of its low sugar and high protein content, plain Greek yogurt is an excellent choice for those monitoring their blood sugar levels, including individuals with pre-diabetes or type 2 diabetes. The high protein and fat content in full-fat or low-fat versions help slow the absorption of carbohydrates, preventing the sharp blood sugar spikes associated with sugary snacks. A controlled study demonstrated that Greek yogurt led to a much lower blood sugar spike compared to regular yogurt, highlighting its metabolic benefits. The combination of protein, fat, and probiotics provides a satiating snack that supports stable energy levels throughout the day.
Making Plain Greek Yogurt a Delicious Part of Your Diet
For those who prefer a less tart taste, there are many ways to sweeten plain Greek yogurt naturally and healthily. Here are a few ideas:
- Fresh or Frozen Berries: Blueberries, raspberries, and strawberries are naturally sweet and packed with antioxidants.
- A Drizzle of Honey or Maple Syrup: A little goes a long way. Use sparingly to add a touch of sweetness.
- A Sprinkle of Cinnamon or Vanilla Extract: These spices add flavor complexity without any sugar.
- Chopped Nuts or Seeds: Adds healthy fats and crunch, which can help increase satiety.

Conclusion: The Bottom Line on Sugar Content
In conclusion, plain Greek yogurt is not high in sugar. Any sugar present is natural lactose, which is significantly reduced during the straining process compared to regular yogurt. This makes it a fantastic, low-sugar, high-protein food option that promotes satiety and supports stable blood sugar levels. By choosing plain and adding your own healthy flavorings, you gain control over your sugar intake, making it a versatile and healthy choice for almost any diet.
Frequently Asked Questions
What is the difference between natural sugar and added sugar in yogurt?

Is low-fat Greek yogurt lower in sugar than full-fat?
No, the fat content doesn't significantly impact the lactose content. The amount of natural milk sugar remains consistent regardless of whether it's low-fat, nonfat, or full-fat.
How much sugar is in a typical plain Greek yogurt serving?
A 5.3-ounce serving of plain Greek yogurt typically contains between 6 and 9 grams of sugar, all of which is natural lactose.
Does plain Greek yogurt spike blood sugar?
Because of its high protein content, plain Greek yogurt helps slow the absorption of carbohydrates and does not cause a significant spike in blood sugar, making it suitable for those with diabetes.
Is Greek yogurt healthier than regular yogurt?
Plain Greek yogurt has higher protein and lower sugar content than regular yogurt, but regular yogurt often contains more calcium. The healthier option depends on your specific nutritional goals.
