Is it gluten free?
Standing in the aisle turning a jar over looking for the word wheat. This is every food on this site that gets asked about, with the short answer and the specific thing to check, so you can stop guessing at the shelf.
It is almost never the food. It is what got added to it.
Pure spices, juices, oils and dairy start out with no gluten in them at all. Nearly every "is this gluten free" question turns out to be a question about the factory instead: what was added for shelf life or texture, and what else ran down the same line that morning. That is why the honest answer to most of these is "usually, but check this one thing", and why the label matters more than the ingredient.
Usually yes 5
- Fruit juice, in general Usually yes
Pure juice or pulp is fine. Gluten gets in through added ingredients or exposure during processing.
- Citric acid Usually yes
Generally fine and recognised as safe by the FDA, in both anhydrous and monohydrate forms.
- Sesame oil Usually yes
Fine, as cooking oils generally are. The risk is the seeds or oil being exposed during processing.
- Condensed milk Usually yes
Gluten free unless flavoured with something that is not. Sweetened and unsweetened are both fine.
- White chocolate Usually yes
Pure white chocolate is fine. The post lists which brands and which chips are safe.
Depends on the type 3
- Sour cream Depends on the type
Fermented cream has no gluten by definition, but it genuinely varies by brand and type. Check.
- Vermicelli noodles Depends on the type
Wheat vermicelli is not. Rice, bean, pea and root starch vermicelli is, including for coeliac readers.
- Soy sauce Depends on the type
Ordinary soy sauce carries roughly 5 ppm of gluten. The post covers brands and how much that means.
Only with the label 2
- Pepperoni Only with the label
Only trust it with a gluten-free label. Some of the ingredients used in pepperoni do carry gluten.
- Joe & the Juice bread Only with the label
They do offer a gluten-free bread in the sandwiches range, so it has to be asked for by name.
Usually no 1
- Cinnamon rolls Usually no
Shop, online and bakery rolls are mostly wheat flour. Ask a bakery for a gluten-free one or make them.
Where gluten actually gets in
- Malt and malt flavouring
- Made from barley. Turns up in drinks, juices and cereals where you would not expect it.
- Anti-caking agents and fillers
- The reason a single spice is usually fine and a seasoning mix often is not.
- Glucose syrup and sweeteners
- Added to juice. Can be wheat-derived depending on the source.
- Shared production lines
- "Made in a facility that also processes wheat" is doing real work on the label, not covering the manufacturer.
- Brewing and fermenting with wheat
- Soy sauce is the usual example, and it is why the gluten-free versions are brewed differently.
- Thickeners and stabilisers
- Mostly a dairy problem, and why sour cream varies by brand when plain cream does not.
Coeliac disease, wheat allergy or sensitivity?
Three different things get described as a gluten problem, and they are not variations of each other. Which one you have decides how strict you need to be, and whether cross-contamination matters at all.
- Coeliac disease
- An autoimmune condition, not an intolerance. Gluten triggers the immune system to damage the lining of the small intestine, and the damage shows on a biopsy. Left unmanaged it leads to malabsorption, anaemia and bone loss. A strict gluten-free diet is the only treatment, and traces genuinely matter.
- Wheat allergy
- A true allergic response to wheat proteins, diagnosed differently again and capable of being immediate and severe. It is wheat that is the problem rather than gluten, so barley and rye may be fine while wheat is not.
- Non-coeliac gluten sensitivity
- Feeling unwell after wheat while testing negative for both of the above. This is the largest group and the least settled, and a 2025 review found that in blinded trials most people in it were not reacting to gluten at all.
Get tested for coeliac disease before cutting gluten out, not after. The blood test looks for antibodies your immune system makes in response to gluten, so removing gluten first can produce a negative result whether or not you have the disease.
High-gluten foods and what replaces them
| Instead of | Use |
|---|---|
| Wheat bread | Gluten-free bread, usually rice, almond or coconut flour |
| Pasta | Rice, quinoa, buckwheat or corn pasta |
| Cakes, biscuits and muffins | Gluten-free flours with a binder such as xanthan gum or psyllium |
| Wheat, barley and rye cereals | Rice, corn or quinoa cereals, and certified gluten-free oats |
| Crackers | Rice, corn or almond flour crackers |
| Beer | Beer brewed from sorghum, rice or millet, or cider |
| Sauces and gravies thickened with flour | Cornflour or arrowroot as the thickener |
| Soy sauce | Tamari, which is brewed without wheat |
Two things worth knowing about the swaps. Gluten-free versions usually cost more, and they are often lower in fibre and fortified B vitamins and iron than the products they replace, because rice and corn starch do not bring what wheat brings. So a gluten-free diet built on substitutes rather than on whole food needs a bit of planning to avoid running short.
This is a starting point, not medical advice. Coeliac disease is a serious condition and tolerance for cross-contamination differs a lot from person to person, so read the label on the actual product in your hand and take anything you are unsure about to your GP or a dietitian.
