HalalYes

KosherYes

KetoNo

It's a starch, so it's carbohydrate. Most types digest like regular starch.

Low-FODMAPYes

Starch is not a FODMAP.

The short answer

Modified food starch is regular starch tweaked to survive cooking, freezing and acid. It's safe and vegan, but check the label for wheat if you avoid gluten, and it's not keto.

Rules by country

🇺🇸 US FDAApproved

🇪🇺 European UnionApproved

🇨🇦 Health CanadaApproved

CaliforniaNo extra rules

Approved in the US, EU and Canada. EFSA re-checked all modified starches (E1404–E1452) in 2017 and saw no need for a daily limit. In the US and EU, a wheat source must be named on the label.

Daily limit: Experts haven’t set a number because normal food amounts are far below any level of concern.

What is it?

"Modified" means the starch was physically or chemically treated, not genetically modified. The changes keep sauces thick after freezing or reheating and stop them turning watery or gluey.

Where it comes from: Starch from corn, tapioca, potato or sometimes wheat, treated with heat, acids, enzymes or small amounts of food-grade chemicals so it holds up to cooking, freezing and acid.

Why it’s in food

Keeps frozen meals and sauces from going watery
Thickens soups, gravies and pie fillings
Gives low-fat foods a creamy feel
Helps flavors and oils mix into powders and drinks

Agar-Agar E406Agar-agar (E406) is a seaweed gel that sets firmer than gelatin. It's safe, vegan, gluten-free, keto and kosher, and is the easiest plant swap for gelatin.Generally safe Carrageenan E407Carrageenan (E407) is a seaweed thickener in plant milks and deli meats. It's approved, but some studies link it to gut inflammation, so people with IBD often avoid it.Use in moderation Cellulose Gum (CMC) E466Cellulose gum (E466, CMC) is a thickener made from wood or cotton fiber. It's approved everywhere and fine for most diets, but studies in mice and a small human trial suggest it can disturb gut bacteria.Use in moderation GelatinGelatin is made from pig, cow or fish parts, so it is never vegan. It's only halal or kosher when certified, because most unlabeled gelatin comes from pork.Generally safe
