A low FODMAP diet is often used to manage symptoms of specific digestive disorders like irritable bowel syndrome. It involves restricting or eliminating certain types of carbohydrates that can trigger digestive issues in some people.
If you’re considering the low FODMAP diet, you may ask, Is corn a low FODMAP food? Can someone who follows a low FODMAP diet enjoy oatmeal? These are just some of the questions you may be asking yourself, especially if you’re used to eating corn products like cornflakes, corn flour, porridge, or cornstarch.
Here’s what you should know.
Can You Eat Corn On A FODMAP Diet?
Yes, certain corn products can be low FODMAP friendly. These include fresh corn, corn on the cob, corn kernels, corn flour, and cornstarch. Other varieties, such as canned corn, corn syrup, and various processed corn foods, contain sugars and additives that make them unsuitable for a low FODMAP diet.
What Is A FODMAP Diet?
A low FODMAP diet is a specialized eating plan[1] that is often used to manage symptoms of IBS[2] and other digestive disorders. FODMAP[3] stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These carbohydrates can be difficult to digest for some people and can lead to symptoms such as bloating, gas, abdominal pain, and diarrhea.
The low FODMAP diet[4] involves restricting or eliminating foods high in FODMAPs and then gradually reintroducing them to identify which ones trigger symptoms. The diet is typically done in three phases:
The Three Phase Diet Approach
1. Elimination Phase: High FODMAP foods are eliminated from the diet for 2 to 6 weeks. Common high FODMAP foods include wheat, rye, barley, onions, garlic, certain fruits (such as apples, pears, and stone fruits), certain vegetables (such as broccoli, cauliflower, and asparagus), legumes, lactose-containing dairy products, and artificial sweeteners[5] like sorbitol and mannitol.
2. Reintroduction Phase: After the elimination phase, high FODMAP foods are gradually reintroduced one at a time in specific quantities. This helps identify which FODMAPs trigger symptoms in individual cases. The reintroduction phase is typically done under the guidance of a registered dietitian.
3. Personalization Phase: Once trigger FODMAPs are identified, a personalized long-term diet plan can be developed. This phase involves avoiding or minimizing the intake of high-FODMAP foods while still maintaining a varied and balanced diet.
Not all high FODMAP foods need to be permanently eliminated, as some individuals may tolerate certain FODMAPs better than others.
It is important to note that the low FODMAP meal plan is not meant to be a long-term diet or a weight loss tool but rather a way of identifying trigger foods and managing symptoms.
Working with a healthcare professional or registered dietitian specializing in digestive health is recommended to ensure proper implementation and avoid nutrient deficiencies while following an overall healthy diet.
Which Corn Is FODMAP-friendly?
When it comes to corn, it’s important to understand that not all forms of corn are created equal in terms of their FODMAP content. Here’s a breakdown of different corn products and their FODMAP status:
Corn Produce
- Fresh Corn: Fresh corn, including corn on the cob, is generally considered low in FODMAPs and can be enjoyed on a low FODMAP diet. However, it’s essential to moderate your portion size to avoid consuming excessive amounts of fructose,[6] a naturally occurring sugar in corn that can contribute to digestive symptoms in large quantities.
- Canned Corn: Canned corn may contain added ingredients such as sugar, salt, or high fructose corn syrup, potentially increasing its FODMAP content. It’s recommended to choose canned corn without added ingredients, or opt for fresh or frozen corn to be safe.
Corn Products
- Corn Flour: Corn flour is made from dried corn and is considered low in FODMAPs,[7] as it primarily contains starch. However, checking for other high FODMAP ingredients is essential if purchasing pre-made products containing corn flour.
- Cornstarch: Cornstarch is extracted from corn and is a common thickening agent used in cooking and baking. It is considered a low-FODMAP food and can be used in small amounts as part of a low-FODMAP diet.
- Corn Syrup: Corn syrup is a sweetener derived from corn and is high in FODMAPs.[8] It should be avoided on a low FODMAP diet.
- Corn-based Snacks and Products: Corn-based snacks such as corn chips, canned baby corn, corn tortillas, and sweet corn cereals can vary in their FODMAP content… It’s important to read labels and avoid products that contain additional high FODMAP ingredients like onion or garlic powder.
With all this being said, it’s important to note that everyone’s tolerance to FODMAPs can vary. That’s why monitoring your individual response and consulting with a registered dietitian is recommended. They should ideally specialize in the low FODMAP diet to tailor the approach to your specific needs.
Recipes With Corn Low In FODMAP
If you want to create a delicious dish including corn but keep it low FODMAP, you’ll want to avoid pairing it with high FODMAP foods. The best low FODMAP corn dish is a simple salad with fresh corn kernels sprinkled on top for extra crunch. You can also make cornbread, homemade corn tortillas, and corn pastries.
Here’s an example of a delicious recipe using corn that is low FODMAP:
CORN AND ZUCCHINI FRITTERS
Ingredients:
- 1 cup fresh corn kernels (cut from 2-3 ears of corn)
- 1 medium zucchini, grated
- 2 green onions (green parts only), finely chopped
- 1/4 cup gluten-free all-purpose flour
- 2 tablespoons finely chopped fresh parsley
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 eggs, beaten
- Olive oil for frying
Instructions:
- In a large bowl, combine the corn kernels, grated zucchini, green onions, gluten-free all-purpose flour, chopped parsley, salt, and black pepper.
- Add the beaten eggs to the bowl and mix everything together until well combined.
- Heat a thin layer of olive oil in a large skillet over medium heat.
- Spoon about 2 tablespoons of the corn and zucchini mixture into the skillet for each fritter, pressing down gently with the back of the spoon to flatten.
- Cook the fritters for 2-3 minutes on each side or until golden brown. You may need to work in batches depending on the size of your skillet.
- Once cooked, transfer the fritters to a paper towel-lined plate to drain excess oil.
- Serve the corn and zucchini fritters warm as a side dish or as a light meal. You can also serve them with a dollop of lactose-free sour cream or a side of low-FODMAP dipping sauce.
Note: Feel free to add herbs or spices of your choice to enhance the flavor of the fritters. Ensure any additional ingredients are low in FODMAPs and suit your dietary needs.
Also, remember to adjust the portion sizes and ingredients according to your own tolerance and recommendations from your healthcare team.
Conclusion
Corn can be a good option for those on a low FODMAP diet, but pay attention to its various forms. Choose fresh corn without any additives, added sugars, or excessive salt, and stay away from processed corn products which usually contain ingredients that increase its FODMAP content.
