What Is Maltitol And Why You Should Avoid It

Kibi Kibi @ May 31, 2026

Let's talk about the ingredient that's been quietly crashing the 'healthy snack' party for years.

You've seen it on labels. You've probably eaten it without knowing. And if you've ever had a 'sugar-free' chocolate bar and wondered why your stomach wasn't thrilled with you afterward — hi, that was probably maltitol.

So, What Even Is Maltitol?

Maltitol is a sugar alcohol — a type of sweetener made by hydrogenating maltose (a sugar derived from starch). It tastes about 75–90% as sweet as sugar, has a similar texture, and crucially — it lets brands put 'No Added Sugar' or 'Sugar-Free' on the packaging without technically lying.

Which is, to put it gently, a masterclass in fine print.

The Problem With Maltitol

Here's what brands conveniently forget to mention:

1. It Still Raises Your Blood Sugar

Unlike some sugar alcohols (like erythritol or xylitol), maltitol has a glycaemic index of around 35–52 — which is significant. For context, table sugar sits at about 65. So yes, maltitol raises blood sugar less than regular sugar, but it still raises it. Considerably. That '0g Sugar' label is doing a lot of heavy lifting.

2. Your Gut Does Not Love It

Sugar alcohols aren't fully absorbed in the small intestine, so they make their way to the large intestine where gut bacteria ferment them. The result? Bloating, gas, and — to put it delicately — bathroom urgency. Most products containing maltitol literally carry a warning about 'excessive consumption may have a laxative effect.' Most people just don't read that part.

3. The Calorie Difference Is Overstated

Maltitol provides about 2.1 calories per gram versus 4 calories per gram for sugar. The saving sounds good until you realise that most maltitol-sweetened products compensate with extra fat and other ingredients to maintain palatability — so the overall calorie count barely shifts.

Why 'Sugar-Free' Is Not The Same As 'Better For You'

This is the part worth remembering: food marketing is extraordinarily good at using technically true statements to imply things that aren't really true.

'No Added Sugar' can mean a product is sweetened with maltitol, which spikes your blood sugar and wrecks your gut. 'Sugar-Free' can apply to something with 400+ calories per 100g. 'Healthy' is not a legally defined term. None of this is illegal. All of it is misleading.

What We Use Instead (And Why It Actually Matters)

At Kibi Kibi, we sweeten with date syrup and let whole ingredients like oats, nuts, and seeds carry the natural sweetness. Our Bliss Balls are sweetened entirely by dates — zero added sugar of any kind, including sugar alcohols.

Our Super Granola uses date syrup and Tata FOS (fructooligosaccharides) — a prebiotic fibre that actually feeds your gut bacteria rather than confusing them. It's sweet enough to enjoy, honest enough to feel good about.

The goal was never to trick your taste buds. It was to make something that's genuinely better — not just better on a technicality.

The Quick Checklist: How To Spot Maltitol On A Label

Look for 'maltitol,' 'maltitol syrup,' or 'hydrogenated glucose syrup' in the ingredients list
Be suspicious of any product that's 'sugar-free' but inexplicably sweet
Check the nutrition label — if carbohydrates are high but 'sugars' is listed as 0g, something's doing the sweetening work that isn't being counted
If the product carries a laxative warning, that's maltitol's fingerprints

The Bottom Line

Maltitol isn't a scandal. It's a legal ingredient used by plenty of brands who'd genuinely prefer you didn't look too closely at how it works.

You deserve snacks that are honest — not just ones that have technically found a way around the truth. Read the label. Know what you're eating. And maybe give those 'sugar-free' chocolates a second look before you assume they're doing you any favours.

Your gut will thank you. Genuinely this time.
