Keto, Insulin & the Truth About Maltitol: A Science-First Guide for Type 2 Diabetics in Germany
You’re standing in Edeka. One hand on a “zuckerfrei” chocolate bar. The other holding your phone. The label looks promising—low sugar, keto-friendly buzzwords—but there it is in small print: Maltitol (E 965). As a Type 2 diabetic following keto, your real question isn’t calories. It’s insulin.
Will this spike your blood sugar? Will it knock you out of ketosis? And why does every “low-carb” product seem to play label roulette?
This is where science—not marketing—matters. And where the right tool can save you from insulin surprises.
The Hidden Problem: Maltitol, Insulin, and Keto Confusion in Germany
Maltitol is a sugar alcohol widely used in Germany, especially in products at Edeka and dm Drogerie: protein bars, diabetic sweets, chewing gum, even “fitness” snacks. Under EU law, it’s labeled as E 965 and regulated by the European Food Safety Authority (EFSA).
Here’s the nuance most labels don’t explain.
From a regulatory standpoint, maltitol is considered safe. EFSA evaluations confirm it does not pose cancer risks or major metabolic dangers at typical intake levels, and no Acceptable Daily Intake (ADI) limit was deemed necessary due to its safety profile (EFSA evaluation).
However, safety is not the same as keto suitability—especially for Type 2 diabetics managing insulin resistance.
Maltitol has a glycaemic index of around 35. That’s lower than sugar, but far from zero. Unlike erythritol, maltitol is partially absorbed in the small intestine, which means it can raise blood glucose—and insulin—especially in people with impaired glucose metabolism.
EFSA has also acknowledged ongoing data gaps in genotoxicity testing for maltitol, prompting continued re-evaluation, though no genotoxic risk has been established EFSA call for data.
Germany’s Bundesinstitut für Risikobewertung (BfR) echoes this cautious stance, noting that while no bans or warnings exist, incomplete data suggests moderation is wise—especially for vulnerable groups BfR guidance.
And then there’s the practical issue many diabetics know too well: gastrointestinal distress. Consuming more than 30–40g of maltitol can cause bloating and diarrhea, with severe laxative effects reported above 90g/day clinical review.
So while maltitol won’t poison you—and isn’t banned in Germany—it can quietly undermine keto insulin control if you rely on guesswork.

This is exactly why Food Scan Genius exists.
As a Type 2 diabetic on keto, you don’t need generic “healthy” advice. You need personalized insulin-aware filtering—especially when shopping in real German stores with EU labeling rules.
Food Scan Genius lets you:
- Create a personal dietary profile: Keto + Type 2 Diabetes
- Add maltitol (E 965) as a flagged ingredient
- Scan products instantly at Edeka or dm

“It Changed How I Shop” – A German Diabetic’s Story
“I’ve been Type 2 diabetic for eight years and started keto on my doctor’s recommendation. At dm, I kept buying ‘zuckerfrei’ snacks, but my glucose readings didn’t make sense. Food Scan Genius showed me how often maltitol was the problem. Now I scan everything. My insulin levels are more stable—and shopping is finally stress-free.”

Frequently Asked Questions
Is maltitol allowed in Germany?
Yes. Maltitol (E 965) is authorized in Germany and the EU under EFSA regulation, with no ban or mandatory warning labels.
Does maltitol spike insulin for Type 2 diabetics?
It can. While lower than sugar, maltitol still raises blood glucose and insulin in some Type 2 diabetics due to partial absorption.
Is maltitol keto-friendly?
It is not zero-carb. For strict keto or insulin-sensitive individuals, it may interfere with ketosis depending on quantity.
What does EFSA say about maltitol safety?
EFSA considers maltitol safe at typical intake levels, with ongoing data reviews and no evidence of cancer or genetic toxicity.
How can I avoid insulin spikes while shopping at Edeka or dm?
Using Food Scan Genius allows you to scan products and automatically flag ingredients like maltitol based on your diabetic keto profile.
