11 ‘Healthy’ Snacks That Are Actually Full of Hidden Sugar

Think you’re eating clean? These snacks say otherwise

You’re trying to do the right thing: you skip the chips, pass on the cookies, and reach for something that screams “healthy.” But some of those virtuous-looking snacks are Trojan horses, smuggling in a shocking amount of sugar. It’s sneaky, and frankly, a bit rude.

It’s linked to everything from weight gain to heart trouble. The American Heart Association suggests women aim for no more than 25 grams (about 6 teaspoons) of added sugar a day, and men no more than 37.5 grams (about 9 teaspoons). Sounds doable, right? Well, let’s see how quickly these “healthy” culprits can sabotage those goals. Making informed choices means you get the nutrients you want, but without the sugar crash, you definitely don’t. Happy (and smarter) snacking!

Flavored Yogurt

That little pot of fruity goodness can be a sugar bomb. Sure, plain yogurt is a champ, but once you stir in the strawberry swirls or peach chunks (and the accompanying syrups), things change—free sugars (added sugars) account for 42% of total sugar in flavored yogurts.

A single-serving cup can easily contain 15–25 grams of sugar (some are even higher). Suddenly, your “light” breakfast is pushing your daily sugar limit. Ouch.

Pro tip: Plain yogurt with fresh fruit or minimal honey is a lower-sugar alternative.

Granola and Granola Bars

Oh, granola. The crunch, the oats, the (sometimes) nuts. It feels wholesome. But many brands are absolutely loaded with sweeteners – honey, syrups, and good old sugar. A small handful, or one seemingly innocent bar, might deliver 10–15 grams of sugar, sometimes more. And who really eats just a tiny sprinkle? Portion sizes are key, and often deceptive.

Pro tip: Avoid products listing sugars in the top three ingredients. Opt for brands that use minimal ingredients (e.g., nuts, dates). Better yet, go homemade, as it allows full control over sweeteners.

Dried Fruit

Fruit is good, so dried fruit seems good, yeah? Well, mostly. While drying concentrates beneficial fiber, vitamins, and antioxidants, it also removes water, leaving the natural sugars highly concentrated.

Even a small box of raisins or a few apricots contains a lot of sugar, adding up faster than you think. It’s like nature’s candy – tasty, but best in moderation, not by the bagful. Keep in mind that softer types like raisins or dates can also spike blood sugar faster than whole fresh fruit.

Pro tip: Some commercial brands coat dried fruit (e.g., cranberries and pineapple) with sugar. Opt for unsweetened varieties.

“Healthy” Breakfast Cereals

Walk down the cereal aisle, and you’ll find boxes shouting about whole grains, fiber, and vitamins, but it’s when you flip the box over and check the sugar content that things get interesting—you’ll quickly discover that even cereals that aren’t Frosted Flakes can be surprisingly sweet. Some “adult” healthy options still manage to sneak in 10+ grams of sugar per serving. And again, who pours a “serving size” that looks like it’s for a toddler?

Pro tip: While some cereals like Shredded Wheat (0.7g/100g) and Weetabix (low sugar/fat) are genuinely low-sugar options, many products labeled “healthy” contain hidden sugars. It’s best to check nutrition labels for total sugars and prioritize fiber-rich options (≥3g/serving).

Store-Bought Smoothies

Making your own smoothie? Great. You control the ingredients. Buying one off the shelf or from a smoothie bar? Tread carefully. Many are blended with fruit juices (more sugar), sweetened yogurts, or even sherbet and syrups. A medium-sized commercial smoothie can easily top 30, 40, even 50 grams of sugar. That’s like drinking a dessert.

Pro tip: Check labels for fruit juice content and serving sizes to avoid unintentional overconsumption. Opt for homemade versions with whole fruits, unsweetened yogurt/milk, and veggies for true health benefits.

Protein Bars

These are tricky. Some protein bars are genuinely decent. Others are basically candy bars with a protein sprinkle (we see you, bars with 20 grams of sugar!) They use it to make them taste less like chalk. Always, always read the label and look for bars with high protein and low sugar.

Pro tip: Look for ≥10g protein and ≤6g sugar per bar with whole-food ingredients (nuts, seeds, dates) and minimal additives. Avoid bars where sugar/sweeteners are top ingredients and high-calorie bars (≥300 calories) unless used for intense athletic recovery.

Rice Cakes (the flavored ones!)

Plain rice cakes are, well, plain—not much sugar there. But start grabbing the caramel, chocolate, or apple cinnamon varieties, and you’re eating tons of sugar. That light, airy snack suddenly isn’t so innocent, and it’s the flavoring that gets you.

Pro tip: Choose plain brown rice cakes and add nutrient-dense toppings like nut butter, avocado, or hummus. Also, check labels for terms like “added sugars,” “fructose,” or “maltodextrin” in flavored options.

Sports Drinks

Unless you’re running a marathon or engaged in super intense, prolonged exercise, you probably don’t need a sports drink at all. They’re designed to replenish electrolytes AND provide quick energy, which means sugar, often lots of it. A standard 20-ounce (600ml) bottle can have upwards of 20-35 grams. For context, this equates to roughly 5–9 teaspoons of sugar.

Research shows that water suffices for hydration in most cases, and consuming sports drinks without corresponding energy expenditure can contribute to excessive calorie intake, weight gain, and metabolic health risks

Kombucha (some varieties)

This trendy fermented tea can be great for your gut. But! Not all kombuchas are created equal. Some brands add a hefty dose of fruit juice or cane sugar after fermentation to make them more palatable. One bottle could have 10–20 grams of sugar. Check those labels; the good ones are lower in sugar.

Actionable tips: Opt for plain or ginger-flavored varieties (lower in sugar), and dilute with sparkling water if they are too tart.

Gluten-Free Packaged Snacks

Going gluten-free doesn’t automatically mean healthy or low-sugar. To make up for the texture and taste that gluten provides, manufacturers often add more sugar (and fat) to gluten-free cookies, muffins, and bars. Don’t assume “gluten-free” is a free pass.

Points to be noted: Not all gluten-free snacks are equal; some brands prioritize whole-food ingredients (e.g., nuts, seeds) with minimal added sugar. Always check labels. Also, decode labels: “Organic cane sugar” and “coconut nectar” are still added sugars.

Applesauce (sweetened individual cups)

Apples are naturally sweet. So why add more sugar to applesauce? Convenience, perhaps. Those little individual cups, especially ones marketed to kids, can have added sugars, pushing them into the 10-15 gram range per tiny serving. Look for “unsweetened,” because it tastes just fine!

Key takeaway: While applesauce itself is a nutritious snack, choosing “unsweetened” varieties avoids unnecessary added sugars, which are linked to health risks like weight gain and chronic diseases
