Hidden sugars lurk in ketchup and salad dressings—and toothpaste tastes sweet, too. Here’s how to read labels, make smarter swaps, and understand the latest 2024–2025 science (including xylitol) without falling for sneaky sugar traps.


 



The Hidden Sugar Trap: Ketchup, Salad Dressing… and Toothpaste?!

Spoiler: two of these you swallow; one you shouldn’t. But all three can mislead your brain (and your shopping cart).

Why we keep missing the sugar in “not-so-sweet” stuff <a id="savory-sauces"></a>

When we think “sugar,” we picture desserts or sodas. Yet pantry staples—ketchup, BBQ sauce, pasta sauce, salad dressings—often carry added sugars to balance acidity, boost texture, and keep us coming back for more. Even a single tablespoon of ketchup typically has around 4 grams (≈1 teaspoon) of sugar, which adds up fast when you drizzle freely. Public-health guidance now calls out condiments as common hidden sources of added sugars. U.S. Food and Drug AdministrationCDCHopkins MedicineHealthline

Why this matters for health right now

Global and national recommendations urge limiting added/free sugars because excess intake is tied to weight gain, dental caries, and cardiometabolic risk. WHO suggests keeping free sugars <10% of energy (and ideally <5%); the U.S. Nutrition Facts label lists Added Sugars to help you track them. World Health OrganizationAGESU.S. Food and Drug Administration

Ketchup: the sweetest “savory” on the plate

  • The norm: ~4 g sugar per tbsp (about a teaspoon). Double or triple that for generous squirts on fries or burgers. HealthlineCDC

  • Why it’s there: Sugar tamps down tomato acidity and stabilizes flavor over shelf life. (Check labels for sucrose, high-fructose corn syrup, glucose-fructose syrup, dextrose.) U.S. Food and Drug Administration

  • Reality check: If you use 3–4 tablespoons across a meal, you can knock out a sizable chunk of your daily added sugar limit before dessert shows up. U.S. Food and Drug Administration

Smarter squeeze: Look for “no added sugar” or “unsweetened” ketchups; many brands now rely on spices and ripe tomatoes over sugars. (Scan the Added Sugars line on the Nutrition Facts label.) U.S. Food and Drug Administration

Salad Dressings: when “light” means sweet <a id="salad-dressings"></a>

  • The trick: Lower-fat, shelf-stable dressings often add sugars (or syrups) to rescue mouthfeel and flavor. Ingredient lists confirm this pattern. ScienceDirect

  • Hidden names: cane sugar, honey, agave, corn syrup, fruit juice concentrate, maltose—different names, same “added sugars” bucket. (U.S. labels must still total them under Added Sugars.) U.S. Food and Drug Administration

Smarter drizzle: Choose vinaigrettes with oil + vinegar + herbs, or make a 60-second dressing at home (olive oil, lemon, Dijon, salt/pepper). Your greens shouldn’t come with a dessert. CDC

Toothpaste: sweet taste ≠ dietary sugar <a id="toothpaste"></a>

Here’s the curveball. Toothpaste tastes sweet, but ADA-Accepted toothpastes are not allowed to contain sugar (like sucrose) because that would promote decay. Instead, they use non-cariogenic sweeteners (e.g., saccharin, sorbitol, sometimes xylitol) to mask the bitter flavors of fluoride and abrasives. You’re not meant to swallow toothpaste; the sweet taste is only to make brushing tolerable. ADAColgate

What about xylitol?

  • Dental angle: Xylitol has anti-cariogenic properties (it can reduce S. mutans and caries risk in certain contexts), which is why you’ll see it in gums and some oral-care products. PMCNature

  • Cardio angle (new data): 2024 research linked higher xylitol levels (and, separately, erythritol) to increased platelet reactivity and thrombotic potential in adults at cardiometabolic risk—raising questions about high intake of sugar alcohols in foods/drinks. This doesn’t mean “toothpaste causes heart attacks,” but it’s a reminder to avoid swallowing dental products and to treat “sugar-free” ultra-sweet foods with caution until the science settles. Oxford AcademicPubMedNational Institutes of Health (NIH)Nature

Bottom line: Toothpaste is not a dietary sugar source when used as directed. Enjoy the minty sweetness—spit, don’t swallow—and focus your sugar-cutting energy on the foods you actually eat.

How much is “a lot”? (A quick gut check)

Label-reading playbook you can use today <a id="smart-swaps"></a>

  1. Hunt the “Added Sugars” line on Nutrition Facts. It’s the fastest truth detector. U.S. Food and Drug Administration

  2. Scan ingredients for sugar aliases: corn syrup, glucose-fructose, dextrose, cane sugar, honey, agave, fruit juice concentrate. (Different names—same bucket.) U.S. Food and Drug Administration

  3. Trade-ups that work:

    • Ketchup: switch to no-added-sugar versions; try tomato paste + vinegar + spices for DIY. U.S. Food and Drug Administration

    • Dressings: choose simple vinaigrettes or refrigerated fresh dressings with fewer stabilizers and sweeteners. ScienceDirect

    • Toothpaste: pick an ADA-Accepted paste; for kids, use a smear/pea-sized amount and teach spitting to avoid ingestion. ADA

TL;DR (and a friendly nudge)

  • Yes: Ketchup and many salad dressings commonly hide added sugars.

  • No: Toothpaste doesn’t contain “sugar” (sucrose) if ADA-Accepted, but it tastes sweet from non-cariogenic sweeteners—don’t swallow it.

  • Do: Use the Added Sugars line on labels, and make a couple of easy swaps. Your future self (and teeth) will thank you. U.S. Food and Drug AdministrationADA
