Frequently Asked Questions

Is corn flour always gluten-free, or can it sometimes be contaminated during processing?

Pure corn flour is naturally gluten-free, but cross-contamination during processing or packaging can occur if the facility also handles wheat products. To ensure gluten-free status, look for certified gluten-free corn flour brands.

How do I determine if canned cream corn contains hidden gluten ingredients?

Are corn tortilla chips from restaurants typically safe for someone with celiac disease?

Corn tortilla chips are naturally gluten-free but can be unsafe for celiacs if fried in shared oil with gluten-containing items. Always ask restaurant staff about their frying practices and cross-contamination protocols.

Does corn syrup ever contain gluten or is it always a safe option?

Pure corn syrup is naturally gluten-free and safe for people with celiac disease or gluten sensitivity. However, some flavored or specialty corn syrups may contain gluten-containing additives, so it’s important to check labels.

When a product lists "modified food starch," how can I tell if it's from corn or wheat?

You can’t tell the source from “modified food starch” alone unless the label specifically declares wheat (which is required by law as it’s an allergen). If corn is the source, it may be listed as “modified corn starch” but often isn’t specified.
