In 1982, after working a stint within the meals business, Paul Stitt wrote the ebook Beating the Meals Giants. The time period ultra-processed meals was not invented but, however he was warning individuals again then, and for a few years after that, to desert the choices of the meals business and switch to natural, complete meals which might be nutritious and constructed well being. Paul Stitt may see what the meals have been doing to individuals’s well being, however he did not have all the info we’ve now concerning the risks of ultra-processed meals.
I’ve written about ultra-processed meals earlier than, warning folks that eliminating animal merchandise was not sufficient for good well being. Within the Adventist Well being Examine 2 cohort, ultra-processed meals have been extra harmful than animal merchandise. On this cohort, the individuals who ate probably the most ultra-processed meals had a 14% elevated threat of dying of any trigger.
In one other article, I identified that not all ultra-processed meals have been equally harmful. Natural whole-grain bread and refined white bread are each categorised as ultra-processed meals, however solely one in all them builds well being. Sugar-sweetened and artificially sweetened drinks have been clearly harmful, as have been ultra-processed meals containing animal merchandise and ready-to-eat blended dishes/meals.
Extremely-processed meals are harmful, and also you most likely have sufficient causes to not eat them, however I will offer you yet one more: Most cancers. A number of large-scale potential cohorts have proven us the connection between consuming numerous ultra-processed meals and the chance of getting most cancers and dying of most cancers.
Extremely-Processed Meals and Most cancers in France
One of many first research of ultra-processed meals was produced in France within the NutriNet Santé examine. The cohort was launched in 2009 with a web-based questionnaire. They adopted nearly 105,000 adults for about 7.5 years. Researchers used the NOVA system to determine ultra-processed meals, which embrace merchandise with 5 or extra substances.
This is what the researchers discovered: a ten% enhance within the dietary proportion of UPFs correlated with a 12% general elevated most cancers threat and 11% elevated breast most cancers threat. Amongst individuals with most cancers, UPFs accounted for 18% of their energy, which is comparatively low in comparison with another populations we’ll talk about. However even in France, UPFs have been undoubtedly linked to most cancers.
Extremely-Processed Meals and Most cancers within the UK
In 2023, a analysis article was revealed on the UK Biobank cohort’s expertise with UPFs. This cohort had 197,000 individuals in it who have been adopted for about 10 years. There are nearly 16,000 instances of most cancers and over 4,000 cancer-related deaths on this group.
Extremely-processed meals made up 23% of the whole weight-reduction plan by weight, however 49% by energy. A ten proportion level enhance in UPFs elevated the general threat of most cancers by a few p.c, however the threat of ovarian most cancers was raised by 19%.
Most cancers mortality was additionally elevated by UPF consumption. Each 10 proportion factors larger UPF consumption was related to a 6% enhance in general most cancers dying, a 30% enhance in ovarian most cancers dying, and a 16% enhance in breast most cancers dying. So, ovarian and breast well being have been notably compromised by larger intakes of ultra-processed meals. Maybe this is because of endocrine-disrupting components in these meals merchandise.
Dr. Kiara Chang acknowledged, “The common individual within the UK consumes greater than half of their each day vitality consumption from ultra-processed meals. That is exceptionally excessive and regarding as ultra-processed meals are produced with industrially derived substances and sometimes use meals components to regulate colour, taste, consistency, texture, or prolonged shelf life.”
She added, “Extremely-processed meals are all over the place and extremely marketed with low cost worth and enticing packaging to advertise consumption.. This exhibits our meals atmosphere wants pressing reform to guard the inhabitants from ultra-processed meals.”
Extremely-Processed Meals and Most cancers Throughout Europe
The EPIC Cohort is an intensive potential examine throughout 10 European nations at 23 websites, together with 520,000 people. Consumption of ultra-processed meals, as a proportion of energy, ranged from a low of about 15% in Italy and Spain to about 20% in France, 33% within the Netherlands and Germany, and a excessive of 45% within the UK, as famous above. When the EPIC cohort was analyzed for the impact of meals processing on most cancers charges, researchers discovered that changing 10% of their ultra-processed meals, by weight, of their fashions with minimally processed meals would end in:
- 20% decreased threat of head and neck most cancers
- 27% lower in threat of hepatocellular carcinoma
- 27% lower in threat of colon most cancers
Extremely-Processed Meals and Most cancers within the USA
In November 2025, an evaluation of the Nurses’ Well being Examine II checked out consumption of ultra-processed meals and the chance of early-onset colorectal most cancers precursors, and had at the least two endoscopically confirmed outcomes, with screenings earlier than the age of fifty. The nurses have been adopted for over 24 years, they usually discovered 1,189 instances of early-onset typical adenomas.
On this group, the ladies consumed about 5.7 servings of ultra-processed meals a day, which was about 35% of their complete each day energy. They are saying this was barely decrease than the U.S. nationwide common, which is a bit scary.
However the ladies who consumed the best quantities of ultra-processed meals, or about 10 servings a day, had a 45% larger threat of creating typical adenomas, that are a precursor most related to early-onset colorectal most cancers.
Within the Harvard Gazette, senior creator Dr. Andrew Chan referred to as this a “linear” threat. The extra UPFs an individual ate, the extra polyps they discovered, with no plateau impact. The chance continued to extend with larger intakes.
Plan a Entire Meals Weight loss program, or They Will Select UPFs For You
These intensive research throughout Europe and the US paint a constant image that aligns with what Paul Stitt mentioned 40 years in the past. Meals merchandise made with industrial substances by meals business giants are dangerous to your well being. Right here we discover that they trigger most cancers. The extra you eat, the more severe it will get.
Even with out the precise mechanism, it is clear repair this drawback: Eat much less ultra-processed meals. An entire meals plant-based weight-reduction plan, just like the Hallelujah weight-reduction plan, goes to cut back your ultra-processed meals consumption to mainly zero.
There could also be a spot to have public coverage ban components which might be recognized to trigger most cancers. This may be a superb factor. However you shouldn’t look ahead to the federal government or public coverage to repair your weight-reduction plan. You are chargeable for your individual well being, so maintain your physique. In any case, it is the one one you get to reside in whereas right here on Earth.
Change to Handy Pure Meals As a substitute of UPFs
We’ve mentioned what to do and which switches make sense in our earlier article on ultra-processed meals. There are handy, wholesome meals. You simply must get used to picking these and ensuring they’re in your own home able to seize, as a substitute of ending up selecting no matter is in a merchandising machine or a comfort retailer.
- Apples as a substitute of apple pie.
- Oranges as a substitute of orange juice.
- Nuts and seeds or path combine as a substitute of sweet bars or meat snacks.
- Pure water and even flavored unsweetened water as a substitute of soda pop.
- Entire-grain breads as a substitute of refined white bread. (Clear-label nationwide manufacturers like Dave’s Killer Bread are actually broadly obtainable.)
- Raisins, prunes, and dried apricots as a substitute of sweet.
“For those who do not fastidiously select what to eat, another person will make that selection for you, and they’re going to choose your weight-reduction plan for you based mostly on their greatest pursuits and backside line, not your well being.”
It takes slightly little bit of planning initially, however when you get used to it, it turns into routine, like all the things else in your each day routine. So take this step: Get away from ultra-processed meals to decrease your threat of most cancers and get again to nature.
