Corn is a popular food item, but is it compatible with the FODMAP diet? FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols – these are types of carbohydrates that can cause digestive issues, including triggering symptoms of irritable bowel syndrome (IBS). The FODMAP diet involves eliminating high-FODMAP foods and then reintroducing them gradually to identify specific triggers. The FODMAP content of corn varies depending on the type and processing method. For example, canned corn is generally considered safer than fresh corn, and boiled or grilled corn may be tolerated differently than corn on the cob. Portion size also matters, with small servings of corn on the cob, such as half a cob or 38 grams, being recommended as low FODMAP. Additionally, many corn-based products like corn tortillas, corn chips, and popcorn are considered low FODMAP. However, individual tolerance may vary, and some people with IBS may still struggle with corn due to its insoluble fiber content. Therefore, it is important to consult a dietitian and pay attention to personal experiences when following the FODMAP diet.

What You'll Learn
Canned corn is generally safer than fresh corn
Corn is one of those foods that can be confusing when it comes to FODMAPs. It can be high or low FODMAP depending on a variety of factors. The type of corn, how it is processed, and how much you eat all play a role in determining its FODMAP content.
Fresh corn, for example, can be high FODMAP in moderate portions. Sweet corn, also known as corn on the cob, is the most common variety of fresh corn and has the highest amount of FODMAPs due to its early harvesting, which results in higher sugar content. Therefore, if you are following a low FODMAP diet, you should limit your intake of fresh sweet corn to small amounts, such as half a cob or 38 grams.
On the other hand, canned corn is generally considered safer and lower in FODMAPs compared to fresh corn. Canned corn kernels, in particular, have a low FODMAP serving size of up to one cup or 75 grams. This is because canned corn does not become moderate FODMAP until very large servings of 250 grams or more due to its fructan content. As a result, canned corn can be consumed more freely on a low FODMAP diet.
Additionally, other types of canned corn, such as canned baby corn, have only trace amounts of FODMAPs and can be eaten without restriction. Canned creamed corn, however, should be consumed in smaller portions of 60 grams or less to stay within the low FODMAP range.
In conclusion, while corn can be a tricky food on a low FODMAP diet, canned corn is generally safer than fresh corn due to its lower FODMAP content. However, it is important to monitor your portion sizes and be mindful of any added ingredients or processing methods that may impact the FODMAP levels.

Corn on the cob is low FODMAP in small servings (38g)
Corn on the cob is low FODMAP in small servings of 38 grams, which is equivalent to half a cob. However, it becomes high FODMAP in larger servings, such as a full cob, which weighs around 75 grams. The FODMAP culprit in corn is sorbitol, a naturally occurring polyol, which is a type of short-chain carbohydrate found in some fruits and vegetables. For some individuals, sorbitol is poorly absorbed in the digestive system, potentially triggering symptoms of irritable bowel syndrome (IBS).
The low FODMAP diet is not a fad but is supported by evidence indicating how high FODMAP foods can trigger IBS symptoms. The diet involves eliminating all high FODMAP foods for a set period before slowly reintroducing them to identify specific triggers. Monash University has also tested and verified the FODMAP levels of various corn products.
It is important to note that not all corn products are equal in their FODMAP content. For example, canned corn is generally safer than fresh corn, and boiled, grilled, or fire-cooked corn may have different FODMAP levels than corn on the cob. Additionally, while sweet corn is higher in FODMAPs, many corn-based products are not due to the use of different types of corn. Corn tortillas, corn chips, popcorn, and gluten-free corn flakes are examples of corn-based products that are generally considered low FODMAP.
Furthermore, insoluble fiber in corn can also cause discomfort for some individuals with IBS or other gut conditions, even at low FODMAP portions. Therefore, it is recommended to consult a dietitian when embarking on a low FODMAP diet to determine the best approach for managing symptoms.

Corn tortillas are low FODMAP
Corn is one of those foods that can be tricky to navigate on the FODMAP diet. Fresh corn, such as corn on the cob, can be high-FODMAP in moderate portions. However, many processed corn-based products are low-FODMAP, including corn tortillas, corn chips, corn flakes, cornmeal, and popcorn.
Corn tortillas, in particular, are considered low-FODMAP. This includes both corn tortillas with added gum or fibre, as well as those without. Specifically, corn tortillas with added gum or fibre are low-FODMAP in a serving of 2 tortillas, while those without are low-FODMAP in a serving of 3 tortillas.
It is important to note that corn is a FODMAP at a large enough serving. The processing methods used to make corn tortillas, such as grinding and treating with lime, help reduce the FODMAP content, making a typical serving size usually okay.
Additionally, the type of corn used in corn tortillas may also contribute to their low-FODMAP status. Dent corn, for example, is often used to make corn tortillas and other corn-based products like chips and taco shells. These products are generally low-FODMAP, except when they contain high fructose corn syrup.
Overall, corn tortillas are a great option for those following a low-FODMAP diet, but it is always important to be mindful of portion sizes and check labels for any added ingredients that may impact FODMAP levels.

Corn chips are FODMAP-friendly
Corn and many corn products can be incorporated into a low-FODMAP diet. The FODMAP content of corn products varies, but several corn-based products are acceptable on a low-FODMAP diet.
Corn chips are a great low-FODMAP option. They are typically made with corn, vegetable oil, and salt, and are generally considered safe for those on a low-FODMAP diet. Plain or salted corn chips or tortilla chips are low-FODMAP. It is important to check the labels for added ingredients and avoid corn chips with additional seasonings that may contain onion and garlic, which are high-FODMAP ingredients.
The Monash App is a reliable source for information on FODMAP content in foods, providing a traffic light rating system for different portion sizes. According to the Monash University data, a serving of 50 grams of corn chips is considered low FODMAP. However, at a serving size of 250 grams, corn chips are high in oligos-fructans. Therefore, it is recommended to stay well below 250 grams to maintain a low-FODMAP diet.
Homemade corn tortilla chips can also be made using corn tortillas, extra virgin olive oil, and low-FODMAP seasoning. These homemade chips can be a delightful snack or side dish and can be enjoyed with various low-FODMAP dips.

Corn starch and corn flour are low FODMAP
Corn and many corn products can be included in a low-FODMAP diet. The type of corn and how it has been processed determine its FODMAP content. For example, sweetcorn is higher in FODMAPs, while many corn-based products are not because they use a different type of corn.
Corn starch and corn flour are low-FODMAP foods. In the UK, Australia, and New Zealand, corn flour is the same as corn starch in the US. In some countries, corn flour can contain wheat, so it is important to ensure that it is made from maize and not wheat. Corn flour is the whole corn kernel milled into flour. When corn flour is very coarse, it is called polenta. Maize flour, made from the entire corn kernel, is also low FODMAP. When maize flour is very coarse, it is called polenta, and when it is finely ground, it is called flour.
Corn tortillas, corn chips, and popcorn are also low-FODMAP foods. Canned corn, including kernels and baby corn, is lower in FODMAPs than fresh corn. However, even at low-FODMAP portions, some people with IBS and other gut conditions may find that corn causes discomfort due to its tough exterior and high insoluble fiber content.
