Can Celiacs Eat Potato Crisps? An Essential Guide to Gluten-Free Snacking

November 11, 2025 •

4 min read

An estimated one in 100 people worldwide has celiac disease, requiring them to avoid gluten completely. For those with celiac disease, the question of whether they can celiacs eat potato crisps is not always straightforward, as the safety depends heavily on the specific brand and flavour.

Quick Summary

This guide explains that while potatoes are naturally gluten-free, many crisps are unsafe for celiacs due to added seasonings containing gluten or the risk of cross-contamination during manufacturing. Safe consumption requires careful label checking.

Key Points

Not all crisps are gluten-free: While potatoes are safe, added flavourings and manufacturing processes can introduce gluten.
Read labels carefully: Celiacs must check for explicit gluten-containing ingredients like malt vinegar and wheat flour in seasonings.
Watch for cross-contamination: Products made in shared facilities or with 'may contain' warnings pose a risk for celiacs.
Look for certified labels: For maximum safety, choose crisps with a 'Certified Gluten-Free' mark, like those from Kettle or Popchips.
Beware of popular brands: Some mainstream crisps like Pringles and certain Walkers/Lay's flavours are not safe due to gluten ingredients or cross-contamination warnings.
Homemade is the safest option: For complete control, making your own potato crisps with just potatoes, oil, and salt is the best choice.

The Basics: Are Potatoes Gluten-Free?

At their core, potatoes are tubers, not grains, and are therefore naturally gluten-free and safe for a celiac diet. This foundational fact is what makes simple, homemade potato crisps a perfectly safe snack. The issue arises when potatoes are processed into crisps with other ingredients, or manufactured in facilities that also handle gluten-containing products.

Why Ingredients Matter

Many commercial potato crisps move beyond just potatoes, oil, and salt. Flavourings and coatings are often added to create a variety of popular tastes. These additions are the primary source of hidden gluten. For example, malt vinegar is made from barley and contains gluten, making many salt and vinegar crisps unsafe for celiacs. Similarly, some seasonings use wheat flour or wheat starch as a binder or coating to achieve a desired texture or flavour consistency.

The Crucial Issue of Cross-Contamination

For celiacs, it is not just about avoiding direct gluten ingredients, but also preventing cross-contamination, which can occur when trace amounts of gluten are transferred from one food to another. In a factory setting, this can happen when crisps are produced on shared equipment with other snacks that contain wheat, barley, or rye. Even if the crisp's ingredients are naturally gluten-free, a 'may contain gluten' warning can signal a significant risk for celiacs. This is why certifications and label statements are so important.

Key Labels to Watch For

Certified Gluten-Free: This is the most reliable label for a celiac. It signifies that the product has been third-party tested and contains less than 20 parts per million (ppm) of gluten, meeting strict safety standards. Brands with this certification, like Kettle Chips and Popchips, are typically safe choices.
'May Contain' Warnings: These warnings, such as 'made in a facility that also processes wheat,' should be heeded by celiacs. Even without explicit gluten ingredients, the risk of cross-contamination makes these products unsafe. Brands like Walkers in the UK and some Doritos flavors carry these warnings.
Uncertified Products: Some companies produce crisps that are naturally gluten-free by ingredients but do not carry a formal certification. For celiacs, this is a gamble, as it leaves the door open to potential cross-contamination. When in doubt, always choose a certified option.

Making a Safe Choice: Your Gluten-Free Checklist

To ensure your snack is safe, follow these steps when purchasing potato crisps:

Look for the certification mark: Prioritise products with a 'Certified Gluten-Free' logo from a recognised organisation.
Read the ingredient list carefully: Scan for obvious gluten-containing ingredients like wheat, barley, rye, or malt.
Heed 'may contain' warnings: Avoid any product with a cross-contamination warning, even if the ingredients seem safe.
Research specific flavours: Manufacturers can have different recipes for different flavours, so a safe brand's barbecue flavour may still contain gluten while their sea salt version is safe. Always check each specific product.

Comparison of Gluten-Free and Non-Certified Crisps

To highlight the difference, here is a comparison of two popular crisp types:


Feature	Kettle Chips (Certified Gluten-Free)	Pringles (Not Gluten-Free)
Ingredients	Whole potatoes, sunflower oil, seasoning. Clearly labelled as gluten-free.	Dehydrated processed potato, with wheat starch and flour used in the base mix.
Manufacturing	Cooked in dedicated equipment with protocols to prevent gluten contamination.	Often manufactured on lines that also handle wheat, increasing contamination risk.
Celiac Safety	Safe for individuals with celiac disease due to certification and controlled production.	Unsafe for celiacs due to gluten-containing ingredients and potential cross-contamination.
Labeling	Clearly marked with a 'Certified Gluten-Free' logo.	No gluten-free claims; ingredient list reveals gluten-containing components.

Popular Gluten-Free Crisp Brands

Thankfully, many brands now offer safe options for celiacs. Some brands with verified gluten-free status include:

Lay's (Classic varieties): Frito-Lay lists several of its classic potato chip flavours as gluten-free on its website.
Kettle Brand: Most of their kettle-cooked crisps are certified gluten-free.
Popchips: All Popchips products are officially approved by the Gluten-Free Certification Organisation.

Conclusion: Mindful Snacking for Celiacs

In short, celiacs can enjoy potato crisps, but only with careful label scrutiny and an understanding of the risks involved. While the potato itself is safe, added ingredients and cross-contamination are common pitfalls. Opting for products with a clear 'Certified Gluten-Free' label is the safest and most reliable approach. By being a vigilant consumer, you can easily navigate the snack aisle and find delicious, safe potato crisps to enjoy.
