How it works

It reads each ingredient and looks it up in the same food list the Gluten app uses to check every recipe, filed under groups like wheat, dairy, nightshades and high-FODMAP foods, with the rules for 49 allergies, diets, conditions and life stages.

  • Each ingredient is read with what’s in its brackets, so “soy sauce (wheat, soybeans)” counts the wheat.
  • “Free” words count: gluten-free pasta is read as gluten-free, and dairy-free cheese as dairy-free.
  • Words like “organic” or “2 cups” don’t change anything. A word it can’t read makes the answer “check first”, never “can eat it”.
  • For a toddler or a baby, round and hard foods like grapes and whole nuts come back as “check first”: fine cut small or ground, a choking risk whole.

Cooking for more than one diet?

Add everyone you cook for, with their allergies, diets and ages. Gluten checks every recipe for each of them and tells you what to change for anyone who can’t eat it as written. It’s free.

Questions

Is the food allergy checker free?

Yes. There’s no signup, no account and nothing to install. It uses the same food checker the Gluten app runs on every recipe.

Can it check for more than one person?

Yes. Add up to four people, each with their own allergies, diets and conditions, and it answers for each of them at once. A toddler, a pregnant parent and someone with celiac disease can all get an answer for the same food.

What do the answers mean?

“Can eat it” means nothing in what you typed breaks their restrictions. “Check first” means something needs a look: a food that’s only fine cut small for a toddler, one that’s often made with wheat, or a word we don’t know. “Avoid” means it has something their restriction rules out, and we name it.

Why does it say it doesn’t know a food?

It only answers for foods it knows. When it can’t read a word, like a brand name or a dish such as pad thai, it says so instead of guessing. Paste the ingredient list from the label and it checks each ingredient.

Does it check for cross-contact?

No. It reads ingredients, not how a food was made. A label’s “may contain” line is read like an ingredient, but shared fryers, kitchens and factories don’t show up in an ingredient list, so read the label and ask when you eat out.

Is this medical advice?

No. It’s a cooking aid that checks foods against the restrictions you pick. Always read labels, and talk to your doctor or dietitian about what’s right for you.

Gluten gives food ideas, not medical advice. Recipes are checked against the restrictions you enter, but always check labels for allergens and cross-contact, and talk to your doctor or dietitian about your diet.
