Your Guide to Gluten-Free Label Reading
Celiac Awareness Month – Blog 3
Living gluten-free? You’ve probably seen the “gluten-free” label on products – and while it’s a helpful start, truly safe shopping means reading beyond the front of the package, especially when that gluten free label is missing.
This guide offers simple, practical tips (based on Canadian regulations) to help you confidently decode food labels and spot hidden gluten.
Hidden Gluten: The Sneaky Stuff
Gluten isn’t always obvious. It can hide behind unfamiliar ingredient names or show up in foods you wouldn’t suspect.
Here are a few ingredients that might contain gluten:
- Malt (e.g., malt extract, flavouring, syrup, vinegar) – typically made from barley
- Soy sauce – traditional versions usually contain wheat
- Brewer’s yeast – byproduct of beer-making, typically not gluten-free
- Modified food starch – often gluten-free, but can be wheat-derived
- Natural or artificial flavours – usually safe, but gluten can sometimes be used as a carrier
And here are some everyday foods where gluten can unexpectedly appear:
- Salad dressings and marinades
- Soups and gravies
- Deli meats and sausages
- Seasoning blends
- Candy and chocolate
- Ice cream and yogurt
- Breakfast cereals
BROW-sing the Ingredient List: Your First Clue
When it comes to eating gluten-free with confidence, the ingredient list can be your best friend. To help you scan it like a pro, just remember the acronym BROW:
- Barley – Found in malt, malt extract, malt flavouring, barley flour, barley pearls, and more
- Rye – Typically easy to identify, often in rye bread, crackers, or cereals
- Oats – Must be specifically labelled “gluten-free oats” due to risk of cross-contamination
- Wheat – Watch for its many names: spelt, durum, kamut, semolina, farina, graham flour, wheat berries
Also keep an eye out for triticale, a hybrid of wheat and rye that also contains gluten.
If any of these are listed (unless oats are certified gluten-free), the product is not safe for someone with celiac disease.
“May Contain” Labels: What They Really Mean
These statements alert you to possible cross-contact with gluten-containing ingredients during manufacturing. Here’s how to navigate them, based on Health Canada guidance:
If the product is labeled “gluten-free”
In Canada, a gluten-free claim means the product contains less than 20 parts per million (ppm) of gluten. Even if a “may contain wheat” warning appears, the product is still considered safe for people with celiac disease. The gluten-free claim is your most reliable guide.
If the label says “may contain wheat” but there’s no gluten-free claim and no BROW ingredients listed
While no gluten-containing ingredients are declared, cross-contact could still have occurred. Health Canada advises people with celiac disease to avoid these products to reduce the risk of exposure.
If you have a wheat allergy
This is different from celiac disease. Even trace amounts of wheat protein can trigger an allergic reaction. If you have a wheat allergy, it is important to avoid all products with a “may contain wheat” warning – even those labeled gluten-free – because the label refers to gluten content, not wheat protein specifically.
Bottom line:
- A “gluten-free” label = safe for people with celiac disease
- A “may contain wheat” warning with no gluten-free claim = not recommended
- A wheat allergy = avoid all “may contain wheat” products
Thanks to Canadian labelling laws, any gluten source (wheat, barley, rye, oats*, triticale) must be clearly identified in the ingredient list or in a separate “Contains” statement. Still, label reading takes practice.
