Gluten-Free Pasta vs Regular Pasta: Nutrition Data Compared
Switching to gluten-free pasta is a necessity for anyone managing coeliac disease or gluten sensitivity — but what actually changes on your plate, nutritionally speaking? Using official figures from the USDA FoodData Central database, we can look at cooked corn-based gluten-free pasta side by side with cooked enriched regular pasta and see exactly what shifts when you make the swap.
The Numbers at a Glance
All values below are per 100 g of cooked pasta, as recorded by USDA FoodData Central.

| Carbohydrate | 27.9 g | 30.6 g |
| Dietary Fiber | 4.8 g | 1.8 g |
| Protein | 2.63 g | 5.8 g |
| Total Fat | 0.73 g | 0.93 g |
| Iron (Fe) | 0.25 mg | 1.28 mg |

What You Gain by Going Gluten-Free
Considerably More Fiber
This is arguably the most striking difference in the table. The gluten-free corn pasta delivers 4.8 g of dietary fiber per 100 g, compared with just 1.8 g in the enriched regular pasta — that is more than 2.6 times as much fiber in the same weight of cooked pasta. For gluten-free eaters who sometimes worry that their alternative grains will leave them short on fiber, corn pasta is a genuinely strong performer here. Higher fiber content in a meal is associated with slower digestion, which can contribute to a more gradual rise in blood sugar and a greater sense of fullness after eating. This is a useful characteristic when you are building a satisfying, balanced meal.
More Magnesium
The gluten-free corn pasta also leads on magnesium, providing 36.0 mg per 100 g versus 18.0 mg in regular pasta. Magnesium is involved in hundreds of enzymatic processes in the body, and it is a mineral that people who have had prolonged gut inflammation from undiagnosed coeliac disease may have depleted stores of. Seeing it present at double the level in the corn pasta is a quiet win.
More Zinc, Slightly Less Fat, and Zero Added Sodium
Gluten-free corn pasta edges ahead on zinc too — 0.63 mg versus 0.51 mg per 100 g. It also carries 0.73 g of fat compared with 0.93 g, a modest but real difference. Perhaps most practically useful for anyone watching sodium intake: the gluten-free pasta records 0.0 mg of sodium per 100 g, while the regular pasta variety measured here — which is the enriched, with-added-salt version — contains 131 mg per 100 g. If you are cooking from scratch and salting your own water, that is a meaningful baseline difference in the pasta itself.
What You Give Up by Going Gluten-Free
Protein — a Significant Gap
Regular enriched pasta provides 5.8 g of protein per 100 g. Gluten-free corn pasta provides 2.63 g — less than half. For someone eating a large 200 g cooked serving, that gap translates to roughly 6 g less protein from the pasta alone. Wheat pasta’s protein is largely gluten, which is precisely what gluten-free eaters must avoid, but the practical consequence is that corn pasta is a weaker protein source at the table. The kitchen fix is straightforward: lean on protein-rich sauces, stir in legumes, top with cheese, eggs, or meat, or pair with a protein-rich side. The pasta itself is doing less of the protein heavy lifting.
Iron — Enrichment Makes a Real Difference
Regular enriched pasta contains 1.28 mg of iron per 100 g. The gluten-free corn pasta contains just 0.25 mg — roughly one-fifth of the amount. This gap exists primarily because conventional wheat pasta is enriched with iron after milling, a process not uniformly applied to gluten-free alternatives. Iron deficiency is already a common concern among people newly diagnosed with coeliac disease due to prior intestinal damage. Knowing that a routine pasta meal provides far less iron from this source is important context for building a diet that compensates elsewhere — through meat, legumes, leafy greens, and fortified gluten-free products where available.
Fewer Calories, But Also Fewer Carbohydrates Overall
The gluten-free pasta has 126 kcal and 27.9 g of carbohydrate per 100 g; regular pasta has 157 kcal and 30.6 g. These differences are moderate and may matter depending on your individual goals. A lower calorie density is not inherently a drawback, but it is worth knowing if you are cooking for children or anyone with higher energy needs.
What This Means in Your Kitchen
Understanding these nutritional differences can shape how you build your meals, not just which pasta you drop in the pot.
- Boost your protein deliberately. With corn pasta at 2.63 g protein per 100 g versus 5.8 g in regular pasta, plan your sauce and toppings to close the gap. A bolognese, a legume-rich puttanesca, or a scattering of toasted pumpkin seeds all help.
- Leverage that fiber. At 4.8 g fiber per 100 g, corn pasta can anchor a filling meal. Pair it with vegetable-heavy sauces rather than creamy ones to keep the fiber advantage working for satiety.
- Seek iron elsewhere on the plate. Regular pasta’s 1.28 mg iron per 100 g versus 0.25 mg in the gluten-free version is a gap that adds up. Spinach in your sauce, a side of lentils, or GF bread made with iron-fortified flour can help offset this.
- Check your GF pasta brand. The data here reflects one specific product. Blends made from rice, quinoa, chickpea, or lentil flour will have different profiles — some much higher in protein.
- Mind the sodium baseline. The regular pasta here already brings 131 mg sodium per 100 g before you add sauce. If you cook gluten-free corn pasta (0.0 mg sodium), you have full control over seasoning from scratch.
About This Data
All figures in this article come from USDA FoodData Central (fdc.nal.usda.gov). The gluten-free pasta entry is “Pasta, gluten-free, corn, cooked” (FDC ID 168900); the regular pasta entry is “Pasta, cooked, enriched, with added salt” (FDC ID 169751). Data were retrieved on 2026-07-20. It is important to note that nutritional values vary by brand, manufacturing process, ingredient blend, and batch. Always check the label of the specific product you are buying, particularly for iron and protein, where gluten-free pasta formulations differ widely.
Frequently Asked Questions
Does gluten-free pasta have more or less fiber than regular pasta?
Based on this USDA data, the gluten-free corn pasta has considerably more fiber: 4.8 g per 100 g cooked, versus 1.8 g per 100 g for the enriched regular pasta. That is more than 2.6 times the fiber in the same serving size.
Is gluten-free pasta lower in protein?
Yes, significantly so for this corn-based variety. At 2.63 g of protein per 100 g, it provides less than half the protein of enriched regular pasta at 5.8 g per 100 g. Choosing protein-rich sauces or pairing with legumes is a practical way to compensate.
Why is there so much less iron in gluten-free pasta?
The regular pasta here is enriched, meaning iron (and other nutrients) are added back after milling. It contains 1.28 mg of iron per 100 g. The gluten-free corn pasta contains 0.25 mg per 100 g. Many gluten-free pastas are not enriched in the same way, making this a consistent area to monitor in a gluten-free diet.
Is gluten-free pasta lower in calories?
According to this data, yes. The gluten-free corn pasta provides 126 kcal per 100 g compared with 157 kcal per 100 g for the enriched regular pasta. The carbohydrate totals are also slightly lower: 27.9 g versus 30.6 g per 100 g respectively.
