SmartSweets are a better option than traditional candy, but calling them “healthy” is a stretch. A bag contains only 3 grams of sugar and around 100 calories compared to roughly 20+ grams of sugar in a standard bag of gummy bears. That’s a real improvement. But the ingredients that replace that sugar come with their own trade-offs, and the high fiber content can cause digestive problems if you’re not careful.
What’s Actually in SmartSweets
SmartSweets replace the corn syrup found in regular candy with two main ingredients: allulose and soluble tapioca fiber. Allulose is a low-calorie sweetener that tastes like sugar but isn’t absorbed by the body in the same way. Monk fruit extract provides additional sweetness. Together, these let the candy hit familiar sweet notes without spiking your blood sugar the way regular gummies would.
The fiber content is where things get interesting. A single bag packs about 28 grams of fiber, which is close to an entire day’s recommended intake for most adults (the current guideline is 14 grams per 1,000 calories consumed). That fiber comes from soluble tapioca fiber and isomalto-oligosaccharides (IMOs). SmartSweets previously counted IMOs as fiber on their labels, but these compounds are now reclassified as non-digestible carbs rather than true dietary fiber. The company has since added a different type of soluble tapioca fiber that does qualify as fiber, but IMOs remain in the formula as well.
How It Affects Blood Sugar
One genuine advantage of SmartSweets is their minimal impact on blood sugar. Allulose has been shown in clinical research to actively reduce blood sugar spikes when consumed alongside other carbohydrates. A study published in BMJ Open Diabetes Research & Care found that 7.5 to 10 grams of allulose taken with sugar significantly lowered blood glucose at the 30-minute mark compared to a placebo. Since allulose isn’t metabolized for energy, you can subtract it (along with fiber) from the total carbohydrate count to get net carbs, which are quite low per bag.
For people managing blood sugar or watching their carb intake, this is a meaningful benefit over traditional candy.
The Fiber Problem
Getting 28 grams of fiber from a single snack sounds like a nutritional win, but your gut may disagree. The Mayo Clinic warns that adding too much fiber too quickly can cause gas, bloating, cramping, and diarrhea. If you already eat a fiber-rich diet with fruits, vegetables, and whole grains, polishing off a bag of SmartSweets could easily push you past your daily needs in one sitting.
Soluble corn fiber and similar added fibers are also more likely to cause digestive discomfort than the fiber found naturally in whole foods. If you eat SmartSweets regularly, starting with half a bag and seeing how your body responds is a reasonable approach. Eating two bags in a day is a recipe for stomach trouble.
Sweet Taste Without Calories Can Backfire
SmartSweets don’t use sucralose, but the broader science on low-calorie sweeteners raises a relevant concern. Research from the Keck School of Medicine at USC found that when the brain registers sweetness without receiving the expected calories, it can increase hunger signals, particularly in the hypothalamus, the brain region that regulates appetite. The sweet taste also failed to trigger the hormones that normally create a feeling of fullness after eating sugar.
This mismatch between sweetness and calories may prime you to eat more later. The effect was especially pronounced in people with obesity. While SmartSweets do contain some calories (around 100 per bag), the sweetness-to-calorie ratio is still far off from what the brain expects, which could subtly influence cravings or snacking behavior over time. This doesn’t make SmartSweets harmful, but it’s worth noting if you find yourself reaching for food shortly after eating them.
They’re Still Chewy, Sticky Candy
From a dental perspective, SmartSweets don’t feed cavity-causing bacteria the way sugar does, since oral bacteria can’t produce acid without real sugar to metabolize. That’s a clear advantage. But the picture isn’t entirely clean. Chewy, sticky candies, even sugar-free ones, leave residue between teeth that’s difficult to clean. If the candy contains acidic flavoring agents like citric acid, those acids can erode tooth enamel directly, no bacteria needed. Research in the Journal of Global Oral Health found that both original and sour varieties of sugar-free candies were potentially erosive, with the damage proportional to the candy’s acidity.
So while SmartSweets are less damaging to teeth than regular gummy bears, they’re not neutral. Rinsing with water after eating them is a simple way to reduce acid exposure.
SmartSweets vs. Regular Gummy Bears
The comparison is straightforward on the nutrition label. A bag of SmartSweets Gummy Bears has about 100 calories and 3 grams of sugar. A comparable serving of Haribo or similar traditional gummy bears contains around 140 calories and 20 or more grams of sugar, nearly all from corn syrup or glucose syrup. SmartSweets also contain zero protein and 33 grams of total carbohydrates, though much of that is fiber and allulose that your body doesn’t process like regular carbs.
If you’re choosing between the two, SmartSweets win on sugar, calories, and blood sugar impact. But the comparison itself reveals something important: the baseline you’re measuring against is candy. SmartSweets are healthier than traditional gummy bears in the same way that baked chips are healthier than fried chips. It’s a relative improvement within a category of food that doesn’t offer much nutritional value to begin with. There’s no protein, no meaningful vitamins or minerals, and the fiber, while technically present, comes from processed sources rather than whole foods.
The Bottom Line on “Healthy”
SmartSweets are a smarter candy choice, not a health food. They deliver dramatically less sugar than regular gummies, don’t spike blood sugar, and are less harmful to teeth. Those are real benefits if you enjoy candy and want to reduce your sugar intake. But the high dose of added fiber can cause digestive discomfort, the sweetness-without-calories dynamic may influence appetite, and at the end of the day you’re still eating a processed snack with no protein or micronutrients. Treating them as an occasional swap for regular candy is reasonable. Treating them as something good for you is giving them more credit than they’ve earned.
