Do you know that feeling? You just want to eat a huge plate of spaghetti without precisely calculating the carbohydrate content per noodle beforehand—or without having a large amount of active insulin in your body afterward that gets in the way during sports or exercise?
It was precisely this desire that led to Zuckerschmuck's GI Pasta being added to our range. Three varieties, all with a low glycemic index, high protein content, and significantly more fiber than classic durum wheat noodles. Here's my honest practical test as a T1 diabetic.
At a Glance: GI Pasta in three varieties
The most important specs from the manufacturer's information:
- Varieties: Spaghetti, Fusilli, Penne (250 g each)
- Glycemic Index: 38 (= low, classic pasta is around 70)
- Protein Content: 32% more than normal durum wheat pasta (Penne and Fusilli), 45% more (Spaghetti)
- Fiber: 112% more (Penne and Fusilli), 146% more (Spaghetti) than classic durum wheat noodles
- Taste and Texture: hardly any difference to normal pasta — bite identical
- Suitable for: Low-carb diet, high-protein diet, low-glycemic diet
My Self-Test: 2 plates of spaghetti, only 3 BE bolus
I'm Sonja, I've lived with type 1 diabetes for 35 years and use a loop consisting of Mylife Ypsopump and Dexcom G6 (via the Mylife CamAPS fx app). Here's my practical test with GI Pasta:
For 2 large plates of spaghetti, without a pre-meal bolus (i.e., without the classic 15-minute pre-meal bolus), I only administered a bolus for 3 BE (= 36 g carbohydrates). The theoretical carbohydrate amount according to the package would have been significantly higher, but the low GI value plus the high protein content significantly slow down the blood sugar rise.
The result: my blood sugar remained in a healthy range, without the usual rollercoaster after a classic pasta meal. No sudden rise, no sharp drop afterward. Exactly what I expected from a low-carb, high-protein pasta.
Important: this is my personal experience report, not a therapy recommendation. Every body reacts differently. Individual bolus calculation should be done by your diabetologist.
Why does blood sugar react so stably?
Three properties of GI Pasta work together in practice:
Low glycemic index (GI 38). The GI indicates how quickly a food raises blood sugar—low values mean a slower rise. Classic durum wheat spaghetti is around 70, GI Pasta is 38.
High protein content. Protein slows down gastric emptying and thus carbohydrate absorption. GI Pasta has between 32 and 45 percent more protein than regular pasta, depending on the variety. In practice, this means: a less steep rise, longer satiety.
High fiber content. Fiber binds water in the stomach and further slows down digestion. More than double (112 to 146 percent more) compared to durum wheat pasta.
This aligns with the DDG Practice Recommendations 2024, which classify fiber-rich and low-glycemic foods as supportive for therapy [1].
How does GI Pasta really taste?
In terms of taste, hardly any difference to classic durum wheat pasta—that was the biggest surprise for us during the first test. Bite, cooking time, sauce absorption: all as usual. Favorite recipes from our test kitchen: Spaghetti Bolognese, Fusilli with Pesto, Penne all'Arrabiata.

GI Pasta vs. normal spaghetti compared
A brief overview for practical comparison:
| Property | Normal Durum Wheat Spaghetti | GI Pasta (Zuckerschmuck) |
|---|---|---|
| Glycemic Index | ~70 (high) | 38 (low) |
| Protein Content | Standard | +32 to +45 % more |
| Fiber | Standard | +112 to +146 % more |
| Bolus Practice (my experience) | full bolus, often pre-meal bolus necessary | reduced bolus, no pre-meal bolus for me |
| Satiety | moderate | longer (protein + fiber) |
| Taste and Texture | familiar | almost identical |
From my point of view: those who love pasta and at the same time want to reduce their bolus or save the pre-meal bolus will find their meal much more relaxed with GI Pasta.
Frequently Asked Questions about GI Pasta
How much bolus do I need for a portion of GI Pasta?
From my experience, significantly less than with normal spaghetti — for me, a bolus for about half the theoretical carbohydrate amount worked, without a pre-meal bolus. This is not a therapy recommendation. Individual bolus calculation should be done by your diabetologist.
Which varieties are available?
Three varieties, 250 g per pack: Spaghetti (bestseller), Fusilli and Penne. Many diabuddies order spaghetti and fusilli or penne and spaghetti together — this covers the most common recipe needs.
How does GI Pasta taste compared to normal noodles?
Surprisingly close to the original, that was the consensus during the first family test. Bite, cooking behavior and sauce absorption are almost identical to classic durum wheat pasta — the difference is mainly visible after the meal, not in the taste.
Is GI Pasta also suitable for type 2 diabetes or athletes?
Low glycemic index plus high protein content are fundamentally properties that many people seek — athletes for muscle building, health-conscious eaters for satiety, people with diabetes for more stable blood sugar levels. Whether it specifically suits your individual situation, please clarify with your doctor or nutritionist.
Where can I find more low-carb foods?
Our complete low-carb range bundles sugar-free sweets, pasta, snacks and more. Specifically for GI Pasta, there is a more detailed profile in the sister article blood sugar-friendly low-carb noodles.
