You can enjoy many kinds of pasta while following the low FODMAP diet, including many Asian noodles. This article is All About Asian Noodles & FODMAPs in particular.
Asian Noodles vs. Italian Pasta
Growing up in the U.S. most of us are familiar with pasta made from wheat and semolina. Semolina is a flour made from durham wheat and is used to make many of the traditional wheat-based pastas that we have always used.
Brands like Ronzoni and Barilla are made with semolina/durham wheat, as example, and if you are eating classic spaghetti with marinara sauce or lasagna, then you are eating that type of pasta.
Asian noodles are quite varied and can be made from wheat, rice, buckwheat, even sweet potato, and some can even include egg.
Asian Noodles Tested by Monash University
Monash has tested the following – and I have included their recommended serving sizes:
Wheat Noodles (which look like ramen in their app image, and seen below): No low FODMAP serving size is recommended. Even just ½ cup (84 g) cooked showed fructan and fructose content. As a point of interest, traditional wheat pasta does have a low FODMAP serving size of ½ cup (74 g) cooked.
Vermicelli Noodles (which look like rice-based in their image): Low FODMAP serving size is 1 cup (113 g) cooked. The small print notes that the serving size is low in FODMAPs. This is presumably due to the fact that they are based on “no” FODMAP rice. Below you can see our friend Ngoc making our low FODMAP Summer Rolls with vermicelli noodles.
Kelp Noodles: Low FODMAP serving size is 1 cup (113 g) cooked. The small print notes that the serving size is low in FODMAPs.
Rice Stick Noodles: Low FODMAP serving size is 1 cup (220 g) cooked.
Soba (made from wheat & buckwheat, seen below): Low FODMAP serving size is 1/3 cup (90 g) cooked. The small print notes that the serving size is low in FODMAPs.
Also please see in our images below that 90 g of cooked Soba was much more than 1/3 cup. As always, use the weights when using the Monash app.
And 220 g of cooked Rice Stick Noodles was much more than Monash’s stated 1 cup as well. As always, use the weights when using the Monash app.
Important Note: Other than for the Wheat Noodles, Monash did not provide Moderate or High FODMAP information. It could very well be that much larger servings can be tolerated. You will only know if you try during your Challenge Phase! As always, eat to your tolerances.
Asian Noodles Tested by FODMAP Friendly
FODMAP Friendly has lab tested the following – and I have included their recommended serving sizes:
Konjac Noodles: Given a low FODMAP “Pass” at ½ “packet” or 125 g, cooked or uncooked (same weight). “Packet” is their terminology.
“Miracle Noodles”: This is a brand name and their products have gone through FODMAP Friendly’s low FODMAP lab certification. These are “shirataki” noodles made from konjac flour. There are spaghetti, fettuccine and capellini shapes and they are low FODMAP in 3-ounce (85 g) portions, drained, right out of the package.
Gluten-Free Rice Pasta vs. Asian Rice Noodles
All of these dishes use a rice noodle that looks very different from gluten-free rice-based pasta, such as that from Jovial. Below you can see Asian rice noodles on left vs. European-style rice pasta on right. Same ingredients, but very different look, taste and texture.
The Jovial pasta (that’s their caserecce on the right above), and brands like it, are re-creating an Italian-style pasta and they look the part!
The ingredients don’t tell the story. As you can see from the image below, the ingredients are the same: rice flour and water. But we all know that they look completely different, whether raw or cooked:
Obviously how the noodles are made is a different process. We like European-style pasta for our capellini and macaroni and cheese, but like the Asian style where called for. As always, we suggest using the pasta that is recommended in individual recipes.
How Do I Know How Much Of The Raw Noodles To Cook?
We think this is a great question. How do you know how much soba to cook, for instance, if the Monash app tells you that you can have 90 g per serving?
First of all, have you ever tried to measure a small volume like 1/3 cup of long, stringy noodles? And secondly, what does 90 g look like? And how much of raw soba do you cook to get 3 ¼-ounces (90 g) cooked?
Test Kitchen Results
I took both soba and pad thai, rice stick type noodles into our Test Kitchen and cooked each of them several times and then notated the average cooked weight. You will see that both types increase in weight considerably when cooked.
Here are the ratios – there is some rounding up and down applied:
Dry soba increases by a factor of 2.83 when cooked.
Handy soba numbers:
Monash says that a low FODMAP serving size is 1/3 cup (90 g) cooked. You can see the 1/3 cup below; the 90 g of cooked soba was almost double that volume. Please note that we found that this volume was not correct per weight; please use their stated weight in your menu planning.
- 1.15-ounces (33 g) of dry soba = 3.25-ounces or 90 g cooked
- 4-ounces (115 g) of dry soba = 11.3-ounces or 324 g cooked
- 6-ounces (170 g) of dry soba noodles = 17-ounces or 482 g cooked
- 8-ounces (225 g) of dry soba noodle = 23-ounces or 652 g cooked
Asian Rice Noodles
Asian rice noodles increase by a factor of 2.63 when cooked.
Handy Asian rice noodle numbers:
Monash says that a low FODMAP serving size is 1 cup (220 g) cooked. You can see the 1 cup below; the 220 g of cooked Asian rice noodles was almost double that volume. Please note that we found that this volume was not correct per weight; please use their stated weight in your menu planning.
- 2.95-ounces (84 g) of dry Asian rice noodles = 7.75-ounces or 220 g cooked
- 4-ounces (115 g) of dry Asian rice noodles = 10.5-ounces or 300 g cooked
- 6-ounces (170 g) of dry Asian rice noodles = 16-ounces or 455 g cooked
- 8-ounces (225 g) of dry Asian rice noodles = 21-ounces or 595 g cooked
Many kinds of Asian-style noodles can be incorporated into your low FODMAP lifestyle, even during your Elimination Phase. We suggest that you use this article, our recipes, and your Monash and FODMAP Friendly apps to make smart choices in your Asian-style cooking. You can stay symptom-free, while eating deliciously!
