Understanding the Low FODMAP Diet
The low FODMAP diet is a temporary elimination diet used to manage the symptoms of Irritable Bowel Syndrome (IBS) by identifying specific carbohydrate triggers. FODMAPs are types of short-chain carbohydrates that are poorly absorbed by some people, leading to gas, bloating, and abdominal pain. When searching for low FODMAP chips, the key is to look for simple ingredients and avoid common high FODMAP flavorings and additives. This guide will walk you through the most common types of low FODMAP chips available, what to look for on labels, and brands to consider, allowing you to enjoy a satisfying crunch without the digestive distress.
Low FODMAP Chip Categories
Plain Potato Chips
Classic potato chips with a simple ingredient list—potatoes, oil, and salt—are typically low FODMAP. The seasonings are where most flavored potato chips become a problem, as they often contain onion and garlic powder, which are high in fructans. Brands like Lay's Classic, Kettle Cooked Original, and Ruffles Original are generally considered safe, but it's always crucial to double-check the label for added ingredients. Kettle-cooked or reduced-fat versions with simple ingredients also often pass the low FODMAP test. For salt and vinegar lovers, some brands are safe, but it's important to read the ingredients, as milk powder or onion powder can be hidden in some formulations. The safest bet is always the unflavored, basic salted option.
Corn Tortilla and Corn Chips
Corn chips are a fantastic low FODMAP alternative, provided they are made from corn flour, oil, and salt without additional high FODMAP additives. A typical low FODMAP serving size is around 50 grams, or about 2 cups, making them a satisfying snack. Look for brands like Fritos Original, Tostitos Scoops or Restaurant Style, and Que Pasa Corn Tortilla Chips. Be wary of flavored corn chips, such as 'nacho cheese' or 'cool ranch,' which almost always contain high FODMAP ingredients. Original multigrain versions, like some Sunchips products, can also be low FODMAP if certified, but a quick label check is always a good idea.
Plantain and Cassava Chips
For grain-free and more exotic alternatives, both plantain and cassava chips offer low FODMAP options. Plain, ripe plantain chips are low FODMAP, but portion size can be important, so be mindful of your intake. Cassava flour is also considered low FODMAP in moderate serving sizes and is a great base for grain-free chips, with brands like Artisan Tropic offering compliant products. As always, confirm that no high FODMAP seasonings have been added. Trader Joe's offers a simple plantain chip option, but checking the label for just plantains, oil, and salt is key.
Vegetable Chips
While marketed as a healthy alternative, vegetable chips require careful scrutiny of the ingredient list. The FODMAP content depends entirely on the vegetables used. Chips made from kale, parsnips, or certain sweet potatoes are potential low FODMAP options. However, many commercial vegetable chips include a high FODMAP mix of ingredients like onion, garlic, or other vegetables that are not low FODMAP. Terra chips offer some safe options, such as their Original and Mediterranean vegetable chips, but reading the ingredients is the only way to be certain.
High FODMAP Ingredients to Avoid
- Garlic powder or garlic salt
- Onion powder or onion salt
- Wheat flour or wheat-based additives (especially if high on the ingredient list)
- Inulin or chicory root extract
- High Fructose Corn Syrup
- Whey or milk powder (for lactose)
- Molasses
- Artificial sweeteners like sorbitol or mannitol
- Natural flavors (unless certified low FODMAP)

Reading Labels to Find Low FODMAP Chips
To ensure your chips are low FODMAP, scrutinize the ingredients list. Start by checking for a FODMAP-certified logo from an organization like Monash University or FODMAP Friendly, which provides a high degree of confidence. If no certification is present, avoid the ingredients listed in the table above, especially garlic and onion powders. The best rule of thumb is to choose 'Original' or 'Sea Salt' flavors, as these have the fewest added ingredients. Note that 'Natural Flavors' can sometimes contain high FODMAP components, so caution is advised unless the product is certified. When in doubt, opt for the simplest ingredient list possible.
Conclusion
Finding low FODMAP chips is entirely possible and doesn't mean giving up your favorite crunchy snacks. By understanding which types of chips are typically safe—like plain potato chips, corn tortilla chips, and cassava chips—and knowing which high FODMAP ingredients to avoid, you can make informed choices. Always prioritize reading labels and selecting options with the shortest, simplest ingredient lists. When you need extra assurance, look for FODMAP-certified products.
