Understanding Sugar in Yogurt: The Difference Between Natural and Added
When reading a yogurt's nutrition label, "Total Sugars" includes both naturally occurring lactose and any added sweeteners. This is a crucial distinction in determining if 19g of sugar is a high amount. Plain, unflavored yogurt naturally contains about 4-9 grams of lactose per serving, while the remaining sugar in a sweetened yogurt is typically added for flavor. For instance, a 6-ounce container of plain yogurt might contain 7-9g of natural lactose, meaning that in a 19g yogurt, up to 12g could be added sugar. Careful label-reading is essential.
The Health Implications of High Added Sugar
Excessive consumption of added sugars has been linked to various health concerns, including weight gain, increased risk of type 2 diabetes, and heart disease. The American Heart Association recommends no more than 25g (about 6 teaspoons) of added sugar per day for women and 36g (about 9 teaspoons) for men. A single 19g yogurt containing a high proportion of added sugar could use up a large percentage of your daily allowance, making it less than ideal for regular consumption. Many manufacturers add sugar to compensate for flavor when removing fat, leading to surprisingly high sugar counts in products marketed as "healthy".
Comparing Different Yogurt Types
Not all yogurts are created equal when it comes to sugar content. Natural, plain, and Greek yogurts generally have the lowest total sugar because they contain only the natural lactose from the milk. On the other hand, fruit-flavored, sweetened, and dessert-style yogurts often have significant amounts of added sugar. The thickness of Greek yogurt comes from the straining process, which also removes some lactose, resulting in a product with higher protein and lower sugar than traditional yogurt. Organic yogurts, while perceived as healthier, have also been shown to contain high levels of sugar.
Comparison of Yogurt Sugar Content (per ~100g)
| Yogurt Type | Typical Sugar Range (g) | Key Sugar Source | Added Sugar Assessment |
|---|---|---|---|
| Plain/Natural Yogurt | 4-5 g | Natural Lactose | Very Low to None |
| Greek Yogurt (Plain) | 4-7 g | Natural Lactose | Very Low to None |
| Children's Yogurt | ~10-14 g | Added Sugar + Lactose | Often High |
| Flavored Yogurt | ~12-22 g | Added Sugar + Lactose | Variable, Often High |
| Organic Yogurt | ~13 g | Added Sugar + Lactose | Variable, Often High |
| Dessert Yogurt | ~16+ g | Added Sugar + Lactose | Very High |
Choosing a Low-Sugar Yogurt
To make a healthier choice, look for plain, unsweetened yogurt and add your own fresh fruit or a minimal amount of honey. When buying flavored yogurt, aim for one with under 10 grams of total sugar per 6-ounce serving, as recommended by some experts. Pay attention to the ingredients list; sugar or its many aliases (e.g., cane sugar, high-fructose corn syrup, fruit juice concentrate) should not be near the top. The new FDA nutrition labels in the US are now required to break down added sugars separately, making it even easier to track your intake. You can also explore low-sugar, plant-based alternatives or simply get used to the natural, less-sweet flavor of plain yogurt.
The Bottom Line on 19g of Sugar
Whether 19g of sugar is "a lot" depends on the context of your overall diet and the source of that sugar. If the majority of that sugar is added, it's a significant amount and can easily contribute to exceeding daily recommended limits. However, if that 19g includes natural sugars from a generous helping of fruit, the nutritional value changes completely. The key takeaway is to read labels carefully, choose plain varieties when possible, and be mindful of added sugars to make healthier choices that support your wellness goals.
Actionable steps for yogurt shoppers
- Read the Ingredients List: Look for "sugar" or its synonyms near the top, which indicates a higher concentration.
- Check for Added Sugar: The nutrition label now includes a dedicated line for "Added Sugars." Compare this number against your daily limit.
- Flavor It Yourself: Opt for plain yogurt and mix in fresh berries or a sprinkle of cinnamon to control the sweetness.
- Look for Greek or Skyr: These strained yogurts are often naturally lower in carbohydrates and sugar.
- Compare Servings: Remember that the sugar content is per serving, and some containers may contain more than one.

Conclusion
While yogurt is a nutritious food, a high sugar count like 19g can undermine its health benefits if those sugars are primarily added. By understanding the difference between natural lactose and added sweeteners, and by actively checking nutrition labels for "Added Sugars," consumers can take control of their intake. Making informed choices, such as selecting plain varieties or opting for products with less than 10g of sugar per 6-ounce serving, is crucial for managing daily sugar consumption and avoiding the potential risks associated with a high-sugar diet.
