Unpacking the Prego Traditional Nutrition Label
For anyone monitoring their sugar intake, the nutrition label is the most important tool. A typical 24 oz jar of Prego Traditional spaghetti sauce lists approximately 9–10 grams of total sugar per standard ½ cup (120g) serving. A single 24 oz jar is stated to contain about five servings. This means that the entire jar contains between 45 and 50 grams of total sugar, which is a considerable amount, even for a sauce.
The Critical Difference: Natural vs. Added Sugars
It's important to distinguish between naturally occurring sugar and added sugar. Naturally occurring sugars come from the tomatoes and other vegetable ingredients in the sauce. However, many sauce manufacturers add sugar to counteract the acidity of the tomatoes and enhance the flavor. For Prego Traditional sauce, about 4 grams of the 9–10 grams of total sugar per serving comes from added cane sugar. This means about 20 grams of the sugar in a full jar is from a non-natural source, contributing to your daily intake of added sugars, which health organizations recommend limiting.
Comparing Prego Varieties: Is Lower Sugar an Option?
Prego offers a range of sauces, and not all have the same sugar content. Their "No Sugar Added Traditional Pasta Sauce" is a direct response to consumer demand for healthier options. This version has only 6 grams of total sugar per serving and 0 grams of added sugar. The 6 grams of total sugar are all from the natural tomatoes, making it a much better choice for those concerned about their sugar consumption. This demonstrates that by simply choosing a different version of the same brand, you can make a significant dietary improvement.
How Prego Stacks Up Against the Competition
When evaluating any food product, it's helpful to see how it compares to other options on the market. For pasta sauce, both sugar and sodium content are key factors to consider. Many high-quality and specialty brands offer sauces with little to no added sugar. The table below illustrates the nutritional differences between Prego and some popular alternatives.
Pasta Sauce Comparison (per ½ cup serving)
| Sauce Brand/Type | Total Sugar | Added Sugar | Sodium | 
|---|---|---|---|
| Prego Traditional | 9-10g | ~4g | 470mg | 
| Prego No Sugar Added | 6g | 0g | 480mg | 
| Rao's Marinara | 7g | 0g | 420mg | 
| Victoria Low Sodium Marinara | 7g | 0g | 120mg | 
| Muir Glen Organic Classic Marinara | 8g | 0g | 390mg | 
Note: Nutritional information can vary slightly by product batch and location. Always check the current label.
The Health Implications of High-Sugar Sauces
High intake of added sugars is linked to a variety of negative health outcomes, including weight gain, increased risk of type 2 diabetes, and poor heart health. While a single serving of Prego Traditional might seem harmless, using the whole jar on a family meal or consistently consuming it can add up quickly and contribute significantly to your daily added sugar limits. The American Heart Association recommends no more than 36 grams of added sugar per day for men and 25 grams for women. Using a jar of Prego Traditional could push you close to or over that limit in just one meal.
Healthier Alternatives to Store-Bought Sauces
For those looking to reduce their sugar intake, there are several simple strategies:
Choose Low or No Added Sugar Sauces
- Check the Label: Opt for sauces with a "No Sugar Added" label. On the new FDA nutrition labels, added sugars are listed separately, making them easy to spot.
- Read the Ingredients: Scan the ingredient list for hidden sugars, which might be disguised as high-fructose corn syrup, dextrose, maltose, or other syrups. Ingredients are listed by weight, so the further down the list sugar appears, the better.
Make Your Own Sauce from Scratch
Making sauce at home gives you complete control over the ingredients. You can start with canned crushed tomatoes, which often contain only tomatoes, water, and citric acid, and add your own seasonings.
- Simple Homemade Sauce Recipe:
- Sauté onions and garlic in a little olive oil.
- Add canned crushed tomatoes (no added sugar) and simmer.
- Season with fresh basil, oregano, and salt to taste.
 
- Enhance Flavor Naturally: Instead of sugar, use natural sweeteners like roasted vegetables (carrots or onions) or a touch of balsamic vinegar to balance acidity.
Enhance Lower-Sugar Jarred Sauces
If making sauce from scratch isn't an option, you can still improve a store-bought version. Add fresh herbs, spices, or a pinch of red pepper flakes to boost flavor without adding salt or sugar. You can also stir in extra vegetables like mushrooms, spinach, or bell peppers for added nutrients and fiber.
Conclusion
While a jar of Prego spaghetti sauce is a convenient option for a quick meal, the Traditional variety does contain a surprising amount of both natural and added sugar. For those seeking to follow a healthier, lower-sugar diet, being a label detective and considering alternatives is crucial. Options like Prego's own "No Sugar Added" version or other brands with no added sugars offer a significant improvement without sacrificing taste. By taking control of your ingredients, you can ensure your favorite pasta dishes are delicious and aligned with your nutritional goals.
