B- 71 / 100 — Very low saturated fat and effectively zero sugar.
🛒 Buy on Amazon →The short answer
Rao’s Homemade Marinara Sauce delivers 2g of protein and 80 calories per 1/2 cup (USDA FDC 2403200). Per 100g that’s 1.6g of protein; per oz, 0.5g. The Labelgrade is B- (71 / 100): Very low saturated fat and effectively zero sugar.
Why this Labelgrade
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | D | 52 / 100 | 1.6g per 100g — below the high-protein bar; not the right product for protein hunting |
| Ingredient quality | B | 75 / 100 | 11 ingredients, recognizable, no significant additive flags |
| Saturated fat load | A+ | 96 / 100 | 1g per serving (0.8g per 100g) — very low |
| Sodium load | C | 64 / 100 | 430mg per serving (98mg per oz) — meaningful per 100g |
| Sugar load | A+ | 96 / 100 | 4g sugar, no added sugar listed |
| Fiber | F | 36 / 100 | 1g per serving — modest fiber contribution |
| Overall | B- | 71 / 100 | Weighted blend: protein 25% · ingredients 22% · saturated fat 18% · sodium 15% · sugar 12% · fiber 8% |

The no-added-sugar label is the whole reputation
Rao’s costs roughly double what a jar of Ragu or Classico does, and the reason fits on the back panel: Italian whole peeled tomatoes, olive oil, onions, salt, garlic, basil, black pepper, oregano. No cane sugar, no corn syrup, no thickeners, no “natural flavor.” That matters because the default move in supermarket pasta sauce is to add a spoonful of sugar to take the edge off tomato acidity — which is why so many jars land at 8, 9, even 12 grams of sugar per serving. Rao’s leaves it out, and the 4g of sugar you see here is simply what’s in the tomatoes. That’s the lowest sugar of any marinara we grade, and it’s a real, label-verifiable distinction rather than marketing.
It’s worth being precise about what that buys you, though. On our scale the clean label drives the sugar (A+) and saturated-fat (A+) dimensions to the top, but it doesn’t lift Rao’s far above the cheaper jars, because they keep sugar modest too — Classico and Newman’s both score an A or A+ on sugar. The honest read: Rao’s earns its premium on taste and an unimpeachable ingredient list, not on a wide nutritional gap. If you love how it tastes, the label gives you nothing to apologize for. If you’re buying it expecting a dramatically “healthier” sauce, the grade says the difference is real but narrow.
Why a B-, not an A: it’s the sodium
So if the ingredient list is this clean, why does Rao’s land at 71 rather than in the A range? Two ceilings, and only one is about the recipe. The structural one is that marinara is a vegetable sauce — 2g of protein and 1g of fiber per serving — so it can’t score like a protein food no matter how good it is at being a sauce. The correctable one is sodium: 430mg per 1/2 cup, which scores a C and is the single biggest drag on the grade. That’s actually the highest sodium of the major jarred marinaras here — a touch above Classico’s 410mg and Newman’s 380mg — and it’s the reason even the best jarred sauce on this page tops out at B-. A spotless label and high sodium are not a contradiction; salt is doing flavor and preservation work, and a short ingredient list says nothing about how much of it there is. Nobody eats just half a cup either, so on a real plate of pasta the sodium is the number to watch, not the sugar.

Frequently Asked Questions
Is Rao's Homemade Marinara Sauce healthy?
For a jarred sauce, it's about as clean as the aisle gets. At 80 calories and 6g of carbs per 1/2 cup, it's a low-calorie, nearly fat-free way to dress pasta, and the ingredient list is just tomatoes, olive oil, onions, garlic, and herbs — no added sugar, no thickeners, no preservatives. The one nutritional catch is sodium: 430mg per half cup (USDA FDC 2403200), which is the highest of the major jarred marinaras we grade.
Why does Rao's Homemade Marinara Sauce get a Labelgrade of B-?
The clean label earns it top marks for sugar (A+, 96/100) and saturated fat (A+, 96/100), and a solid B on ingredient quality. What holds it to a 71 is sodium — 430mg per serving scores a C — plus the structural reality that any tomato sauce is low in protein (2g) and fiber (1g). Those last two are inherent to the food, not a knock on the recipe; the gap between Rao's and the cheaper jars on our scale is small.
Does Rao's really have no added sugar?
Yes. The USDA Branded Foods entry lists 0g of added sugar; the 4g of sugars per serving are naturally occurring in the tomatoes themselves. That's the heart of Rao's reputation — most supermarket sauces add cane sugar or corn syrup to round off the acidity, and Rao's leaves it out. At 4g, it actually carries the least sugar of the marinaras we grade.
Why is the sodium so high if the label is so clean?
Salt does two jobs in a jarred sauce — flavor and preservation — and Rao's uses a real amount of it (430mg per 1/2 cup, 19% of the 2,300mg daily limit). A clean ingredient list doesn't mean low sodium; the two are unrelated. If sodium is your concern, Rao's sells a Sensitive Formula (no onion/garlic) and a lower-sodium line, or you can stretch the jar with no-salt-added crushed tomatoes.
Is 1/2 cup a realistic serving?
Rarely. The label's 1/2 cup (125g) is a modest dressing for one bowl of pasta; most people ladle on closer to a cup, which doubles everything — about 860mg of sodium and 160 calories. The macros here are honest per the label, but scale them to the portion you actually plate, especially the sodium.
