Folic acid is in the flour now — here's the full list
From 13 December 2026 every bag of ordinary white flour in Britain carries added folic acid, by law. Here's what it's in, what it isn't in, and how to actually check.
From 13 December 2026, ordinary white and brown wheat flour in Britain must contain added folic acid. Not “may”. Must. It’s in The Bread and Flour (Amendment) (England) Regulations 2024, with matching rules in Scotland, Wales and Northern Ireland, and the millers started early — most UK flour has been fortified since around October 2025.
So it’s already in the loaf you bought this morning.
I’m not here to tell you that’s good or bad. I’m here because I went looking for a straight list of what it’s actually in, couldn’t find one, and had to build it myself. That’s the bit that annoys me. A change this wide should not require an afternoon of reading statutory instruments to understand.
What actually changed
- 250 micrograms of folic acid per 100g of non-wholemeal wheat flour. That’s 0.25mg.
- Legally required from 13 December 2026. Stock already labelled before that date can be sold until it runs out.
- All four nations, not just England.
- Why: to cut neural tube defects — spina bifida and anencephaly — in early pregnancy. The government estimates around a 20% reduction, roughly 200 cases a year.
This is not a sudden decision. The Scientific Advisory Committee on Nutrition recommended it in 2006 and confirmed it again in 2017. It took eighteen years to reach a bag of flour.
Eighteen years is its own story, and I’ll come back to it.
The part nobody mentions: what’s exempt
Every article I read said “non-wholemeal wheat flour” and stopped. But the exemptions are wider than that, and they’re the useful part — because they’re your options.
Wholemeal is out. All of it. Millers aren’t required to fortify wholemeal wheat flour.
Small mills are out. A mill producing no more than 500 tonnes a year is exempt. That’s your local stoneground mill and the independent bakery buying from it.
Anything that isn’t common wheat is out. The rules cover Triticum aestivum — bread wheat. Not spelt, einkorn, emmer, khorasan, and not durum.
That last one matters more than it sounds, and it’s where I had to rewrite my own list.
Most dried pasta is durum wheat semolina. So is couscous. Neither is covered. I’d put the whole pasta aisle on this list before I checked — it doesn’t belong there. Check the packet: if it says durum wheat semolina, that’s outside the mandate.
Imported finished food is out too. The rule binds flour milled or sold here. A biscuit baked in Belgium with Belgian flour isn’t caught by a British regulation.
How to actually check — you can, mostly
I nearly published something wrong here, so let me be plain about it: folic acid has to appear in the ingredients list.
It shows up inside the flour’s own bracket, like this:
Wheat Flour (Wheat Flour, Calcium Carbonate, Iron, Thiamin, Niacin, Folic Acid)
Calcium, iron, thiamin and niacin have been in there for decades — since 1940s rationing. Folic acid is the new name in that bracket. So on anything with a label, you can check in about four seconds.
Where you can’t check is everything without a label:
- The bakery counter
- The chip shop
- A restaurant or a takeaway
- School and hospital meals
- Anything loose, sliced in front of you, or served on a plate
Ask, and most staff won’t know — not because they’re hiding it, but because it arrived in a sack marked “flour” and nobody told them either.
That’s the honest version of the complaint. It isn’t that this was done in secret. It’s that “read the label” only works if there’s a label, and for a lot of what people eat, there isn’t one.
The full list
Rule of thumb: if it’s made with white or brown bread wheat flour, and it isn’t wholemeal, small-mill or imported, it now contains folic acid.
Bread & bakery
White bread (sliced, unsliced, rolls, baps, buns, bagels, sub rolls) · brown bread · sourdough (unless 100% wholemeal) · burger buns · hot dog rolls · brioche · ciabatta · focaccia · pitta · naan · chapati (if white or brown flour) · wraps and tortillas · crumpets · English muffins · teacakes · hot cross buns · croissants · pain au chocolat · Danish pastries · breadsticks
Cakes, biscuits & sweet things
Cakes of every kind · cupcakes and muffins · biscuits (digestives, rich tea, bourbons, custard creams, Hobnobs) · cookies · doughnuts · scones · waffles · pancakes and crêpes · brownies · shortbread · pretzels · churros · Eccles cakes · fruit turnovers · flapjacks if they contain flour — pure oat ones don’t · cereal bars (many contain wheat flour — check)
Pies, pastry & savoury bakes
Pork pies · meat pies · pasties · sausage rolls · quiche · vol-au-vents · samosas · spring rolls · empanadas
Pizza & flatbreads
Pizza — frozen, chilled, takeaway, restaurant · calzone · garlic bread · dough balls · flatbreads
Coated, battered & breaded
Chicken nuggets · chicken Kievs · turkey dinosaurs · fish fingers · battered fish · fish cakes · scampi · goujons and popcorn chicken · onion rings · battered sausage · tempura · bhajis and pakoras · arancini · mozzarella sticks · breaded ham and mushrooms · katsu · southern fried chicken · corn dogs · Scotch eggs (both the coating and the binding)
Pasta & noodles — read this one carefully
- Dried pasta from durum wheat semolina — NOT covered. That’s most of the dried pasta on the shelf. Check the packet.
- Couscous — NOT covered. Durum again.
- Fresh pasta — ravioli, tortellini, tagliatelle, lasagne sheets — often made with soft wheat flour, so usually covered. Check.
- Egg noodles and wheat-flour wrappers — gyoza, wonton, dim sum skins — covered if made from common wheat.
- Instant and pot noodles — covered.
Ready meals & meal deals
Sandwiches on white or brown bread · wraps · meal-deal baguettes · lasagne (the sheets, plus any roux) · macaroni cheese (the sauce) · pies and anything pastry-topped · microwave burgers · anything thickened with flour
Sauces, gravies & thickeners
The category everyone forgets.
Gravy thickened with flour · white sauce and béchamel · cheese sauce · bread sauce · parsley and onion sauce · soups thickened with flour (a lot of tinned and carton soup) · some curry sauces · packet sauce mixes · tinned spaghetti and ravioli · some stock cubes and stock pots
Breakfast
Toast · crumpets · pancakes · waffles · croissants and pain au chocolat · breakfast muffins
Cereals are a separate story. Cornflakes, Bran Flakes, Weetabix, Shreddies, Cheerios, Special K, Rice Krispies, Coco Pops, Frosties and most branded cereals have been voluntarily fortified with folic acid for years — nothing to do with the flour law. Same vitamin, different route, and it was always on the label.
Snacks
Pretzels · breadsticks · crackers (cream crackers, water biscuits, Ritz) · croutons · some flavoured crisps · baked wheat snacks · snack sausage rolls and Scotch eggs
Stuffing, coatings & your own baking cupboard
Stuffing mix · breadcrumbs · batter mix · tempura mix · pancake mix · Yorkshire puddings · plain, self-raising and bread flour, white or brown — the bag itself
Puddings
Sponge puddings · treacle tart · Bakewell tart · jam roly-poly · crumble topping · profiteroles and éclairs · trifle sponge · Christmas pudding · mince pies · bread and butter pudding · cheesecake base · ice cream cones and wafers
Takeaway & fast food
Fish and chips (batter, and the bread) · burgers (buns) · fried chicken (coating) · kebab pitta and wraps · pizza · Chinese — battered dishes, prawn toast, spring rolls, wontons, noodles · Indian — naan, chapati, samosa, bhaji, pakora · pies from the chippy
Not affected
- Wholemeal flour and anything made from 100% wholemeal
- Small-mill flour — 500 tonnes a year or under
- Durum — most dried pasta, couscous, semolina
- Spelt, einkorn, emmer, khorasan
- Gluten-free products — not wheat flour, so out of scope
- Oats — porridge, oatcakes, pure oat flapjacks
- Rice — rice noodles, rice cakes, rice flour
- Potatoes, unless they’re coated
- Meat, fish, eggs, dairy, fruit, vegetables, nuts, seeds, pulses — unprocessed
- Imported finished food made with non-UK flour
The eighteen years
Here’s what I keep coming back to.
SACN recommended this in 2006. It was confirmed in 2017. It became law in 2024 and bites in 2026. Twenty years, for a change that costs a fraction of a penny per loaf and prevents around 200 cases a year of a condition that ruins lives.
If it was the right call, we were two decades late and thousands of families paid for the delay. If it was the wrong call, no amount of deliberation fixed that either. Either way, the process was the failure.
And the same government that took eighteen years to decide could not, in that time, arrange for a bakery to be able to answer the question “is there folic acid in this?”
That’s not a conspiracy. It’s just nobody being responsible for the last step. Which is most of what’s wrong with how this country is run, and it’s why the Food charter argues that a rule isn’t finished when it’s written — it’s finished when the person at the counter can answer for it.
If you’re pregnant or planning to be, the advice hasn’t changed: take the 400µg supplement. Fortified flour is a floor under the population, not a replacement for it.
