Bacon has long been a favourite of carnivores, but there is growing consumer concern about the health risks posed by nitrites, chemicals used to cure meats.
asserted
Bacon → be → meats
While many experts argue there is no evidence processed meat made without nitrites is safer, retailers have responded to consumer concerns by offering “nitrite-free” products to meet demand.
asserted
retailers → argue → demand
Denhay, the Devon hand- dry-cured bacon specialist, has launched two new back bacon lines in 570 Tesco stores from 21 September – Made Without Nitrites Smoked Back Bacon and Made Without Nitrites Unsmoked Back Bacon (both 200g), both priced at £4.
asserted
both → cure → 4
Waitrose has doubled its Made Without Nitrites range in the past year, with sales up more than 34%.
asserted
Waitrose → double → sales
Sales of its British roast and honey roast hams have risen more than 70% since launching in May, and its unsmoked back bacon is up 22%.
uncertain
bacon → rise → May
Data from Worldpanel by Numerator shows nitrite-free bacon growing steadily while conventional bacon declines, and its share of the fresh bacon category has risen steadily from a small base.
asserted
share → show → base
In the 52 weeks to 6 September 2026, nitrite-free spend reached £34.8m (up 11.4% year on year) and volumes were up to 2.2m kg (up 8.0%), while spend and volume for conventional bacon was 9.2% and 4.9%, respectively.
asserted
spend → reach → bacon
Emer Lowry, a nutritionist at Waitrose, said: “As our customers pay closer attention to on-pack ingredient lists, providing options without added nitrites gives shoppers more choice without compromising on flavour and taste.”
asserted
providing → say → flavour
Marlene Godwin, the managing director of Denhay, said the move was prompted by retailers and shoppers rather than the producer.
asserted
move → manage → retailers
“We definitely don’t want to be telling people what to eat.
asserted
We → want → what
This is about giving bacon lovers choice, not replacement.
asserted
This → give → choice
Retailers were saying customers want this, can you provide it?
asserted
you → say → it
She added: “I can’t speak for shoppers, but I think health consciousness is driving it, and consumers are more interested.
asserted
consumers → add → it
One of the things people said to me was, why not convert everything?
asserted
people → say → everything
Our customers still love traditional cure, but we’re offering another choice.
asserted
we → love → choice
Sodium and potassium nitrates and nitrites are chemicals that are often used to preserve or “cure” meat.
asserted
that → use → meat
Nitrates, which contain one nitrogen and three oxygens atoms, can be converted by bacteria into nitrites, which contain one nitrogen and two oxygen atoms.
asserted
which → contain → nitrogen
Nitrites help to prevent the growth of microbes, including harmful bacteria, and can enhance the flavour and pink colour of meat products.
asserted
Nitrites → help → products
People do not consume these chemicals only through eating meat – nitrates are also provided by vegetables, in particular leafy greens.
asserted
nitrates → consume → vegetables
The Food Standards Agency (FSA) says the key difference is that when nitrates or nitrites are consumed as part of protein-rich foods such as meat, they are converted into chemicals known as nitrosamines, which are thought to be harmful to health.
asserted
which → say → health
“Vegetables provide nitrates alongside beneficial nutrients such as vitamin C, polyphenols and fibre.
asserted
Vegetables → provide → C
These nutrients help to reduce the formation of harmful nitrosamines,” the FSA adds
The World Health Organization’s cancer agency classes processed meat as a group 1 carcinogen, the same category as tobacco, though the known link between processed meat and cancer cannot be directly attributed to nitrites.
asserted
link → help → nitrites
Research suggests eating about 50g of processed meat a day, roughly two rashers of bacon, is linked to a 16% higher relative risk of colorectal cancer.
uncertain
eating → suggest → cancer
The FSA says no single component of processed meat has been identified as the cause, and there is no definitive evidence that nitrites directly cause cancer.
asserted
nitrites → say → cancer
The FSA also says there is no evidence that processed meats made without nitrate or nitrite additives are safer.
asserted
meats → say → additives
It adds that removing them can create food safety challenges, because they help prevent the growth of dangerous bacteria and must be replaced by other methods of preservation.
asserted
they → add → preservation
Gabriela Peacock, a nutritionist and founder of GP Nutrition, said: “People are much more interested in what is actually in their food now.
asserted
what → say → food
They are turning packets over, reading ingredient lists and looking for products that feel a little less processed.
asserted
that → turn → products
If someone enjoys bacon or ham but sees an option made without added nitrates, it can feel like a very easy, positive swap, without having to change the way they eat completely.”
asserted
they → enjoy → way
Peacock said nitrite-free products are often more expensive.
asserted
products → say → ?
“That may be because they are made by smaller producers, use different curing methods or have a shorter shelf life.
uncertain
they → make → life
They may also use higher-welfare meat or more expensive ingredients.
uncertain
They → use → meat
Sometimes, of course, you are paying for the premium positioning and packaging too,” she said.
asserted
she → pay → positioning
She added: “The most expensive option is not automatically the healthiest, just as ‘nitrate-free’ does not give a product a magic health halo.
asserted
free → add → halo
Nitrates and nitrites help to preserve meat and control harmful bacteria, and the Food Standards Agency says there is currently no evidence that processed meat made without them is safer.”
asserted
meat → help → them
