The Grocery Store Struggle Is Real


You're standing in aisle 7. You found a sauce that looks amazing. You flip it over, squint at the tiny ingredient list, and see:


*"Modified food starch, natural flavors, hydrolyzed vegetable protein, dextrin, caramel color..."*


Is it safe? 🤷‍♀️


You Google "is modified food starch gluten-free" — and get 47 conflicting answers.


Sound familiar? You're not alone. This is every grocery trip for the 3+ million Americans with celiac disease.

    Real Stories From Real Users


    Vitamins and supplements are a good example: wheat starch is permitted as an excipient, and because wheat is a major allergen in the US it has to be declared — but on a supplement label it appears in the "other ingredients" line rather than anywhere prominent, which is exactly where people stop reading.

    Celiac Safety Glossary

    Celiac disease
    Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
    Gluten
    Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
    Cross-contamination
    Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces — such as shared cutting boards, toasters, fryers, or utensils — rendering otherwise safe food dangerous for people with celiac disease.
    Malt (Barley)
    Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
    Wheat starch
    Wheat starch is wheat flour that has had the gluten protein washed out. While some European gluten-free foods use codex-grade wheat starch (tested below 20 ppm), it can still trigger reactions in sensitive individuals.
