Can we stop hyperventilating about processed foods?
When I was growing up, lots of adults smoked. My piano teacher smoked during my piano lessons. Cigarette commercials were on TV. Their jingles were so addictive, we in the trumpet section would play them before band practice. Airplanes used to have a smoking section and a no-smoking light that went on before take-off and landing.
Eventually, America turned against tobacco, although it’s still widely consumed in much of the rest of the world. There’s no real debate anymore—tobacco isn’t food, it’s poison.
Now, some folks are comparing processed food to tobacco. It’s true that the packaging and flavoring of both cigarettes and processed foods have been engineered to make them more attractive and more addicting. But let’s not get carried away, like RFK Jr:
“The US health secretary, Robert F. Kennedy Jr., has called ultraprocessed food “poison” and, in at least one case, “genocide,” . . . “
You know what’s poison? Arsenic is poison. Most American rice has significant levels of arsenic.* And it is the least-processed rice that contains the most arsenic. Arsenic in rice concentrates in the outer layers, meaning the bran and husk have the most, which is why brown rice (with bran intact) has significantly higher levels of arsenic than white rice (where these layers are milled off).
You know what else is poison? Acrylamide. It’s a neurotoxin and a carcinogen. Most baked goods contain acrylamide.
Ethanol is poison. Beer, wine and spirits contain ethanol. We tried outlawing ethanol once. It didn’t work.
“A growing body of research suggests that [processed] foods are a major driver of the increase in myriad chronic health concerns including obesity, diabetes, and heart disease, and that processing may matter even more for health than foods’ nutrition content.”
That should read “. . . suggests that *excessive consumption of* such foods . . .” just like excessive consumption of alcohol can lead to obesity, diabetes, cancer, liver disease and alcoholism. It’s the dose that makes the poison, peeps.
Although I generally avoid ad hominem arguments, I have to consider the source here. RFK Jr is discouraging childhood vaccines and has embraced the notorious lies linking thimerosal preservatives and aluminum-based adjuvants to autism. There’s something about a clock striking thirteen that calls into doubt everything that came before.
“Marion Nestle, a preeminent nutrition researcher, gave the MAHA movement some credit. But she cited Kennedy’s embrace of substitutions that mask the actual unhealthy properties of food, such as swapping out artificial dyes for natural ones. She’s concerned that those false wins give a misleading sense of progress.
“Taking color out of ice cream, it’s still going to be ice cream,” Nestle said. “Switching from high-fructose corn syrup to cane sugar, it’s still going to be Coca-Cola. … All I can do is laugh.”
I’m a scientist. I follow the data. So far the data I’ve seen show that abusing processed food can be harmful, but if consumed in modest quantities, it’s harmless. If you’re really concerned about your health, maintain a healthy BMI and blood pressure, exercise regularly, get regular dental care, get your scheduled vaccines and colonoscopy.
*if you want to minimize your intake of arsenic from rice, cook it in an excess of water and pour off the water when it’s done cooking.
Is processed food the new tobacco?

If you want to “maintain a healthy BMI and blood pressure”, it makes sense to reconsider your relationship with preprocessed food. It’s very easy to slip into bad eating habits if that’s all you eat. Yes, you can slip into bad eating habits with less processed food, but odds are the preprocessed stuff has higher fat, sweetener and salt levels making the slide easier and more dangerous. The all bacon diet is self limiting. Highly processed food is designed to keep one eating.
P.S. I just verified that I am human. Why not just have me eat a strip of bacon?
@Kaleberg,
So no Cheerios or Wheaties? No bagel and cream cheese?
I’ve had a healthy BMI blood pressure all my life, without resort to fad diets or antihypertensives and I’ve eaten plenty of processed foods in my life.
It’s easy to slip into alcoholism too, if that’s all you drink.
Americans have lifestyle problems. It’s easy and lazy to blame processed foods (or some other external locus of control) rather than exercise self-discipline. Blaming processed foods is a cop-out.
Joel:
I agree we have to get off our butts and do some type of activity. My Elkhounds and I would walk miles the same as my German Shepherd Minnie. They loved the walk and I needed to walk. It was more interesting in Michigan and Wisconsin as copared to Arizona.
I usually eat me Muesli in the morning after soaking it in some type of fruit juice overnight. Country Life has a pretty good product consisting of: Rolled oats, sunflower seeds, raisins, coconut, oat bran, cane juice crystals, date pieces in oat flour, apple dices, almonds, honey, and hazelnuts.
Blood pressure is low as is cholesterol, triglycerides, etc. It can not cancel out the bad water I was exposed to for two years at Camp Lejeune. Platelets go up and down as well as Red Blood Cells and HGB.
Making sense of what you eat helps.
The assertion of safety of all ultraprocessed foods is no slam dunk: “Researchers showed…that the UPFs that were associated with the highest risk for heart disease included sugar-sweetened beverages and processed meats such as hot dogs and deli meat. UPFs associated with the lowest risk of heart disease included breakfast cereals, yogurt, and some whole grain products. Examples of additives commonly used in UPFs include high-fructose corn syrup, hydrogenated oils, sodium nitrite, and artificial dyes.
While observational studies linking UPFs to cardiovascular disease are growing, rigorous clinical trials – the gold standard of scientific research – are largely lacking. An exception is a small NIH-supported clinical trial conducted in 2019 that linked UPFs to obesity, a risk factor for heart disease.
The study found that when people were given the high UPF diet they ate more calories and gained significantly more weight than when the same people were given a minimally processed diet, even though both diets contained the same number of calories.”

Those who make a blanket defense of all ultraprocessed foods need to “show us the beef”…studies that show that those foods suspected of doing the most harm actually do no harm. Otherwise, they need to acknowledge that ultraprocessed foods cover a multitude of products, some categories of which may well be harmful while others are not harmful (Cheerios.)
@John,
“The study found that when people were given the high UPF diet . . .”
The dose makes the poison.
What happens when they eat a Mediterranean diet that includes a few potato chips and is washed down with a Pepsi? In other words, what harm did the study find when people were given a low UPF diet?
When people consume a high whisky diet, they get the symptoms of alcoholism. When they consume a dram of single malt occasionally, they don’t.
A low polonium diet, on the other hand, will kill ya.
“California’s AB 1264 Introduces the First Legal Definition of Ultra-Processed Food”
Now codified as Section 104661 of the California Health & Safety Code, the statute defines UPF as any food or beverage that contains:
– Surface-active agents; stabilizers and thickeners; propellants, aerating agents, and gases; colors and coloring adjuncts; emulsifiers and emulsifier salts; flavoring agents and adjuvants; or flavor enhancers, excluding spices and other natural seasonings and flavorings; and either:
– High amounts of saturated fat, sodium, or added sugar, or a nonnutritive sweetener or other substance.
Sounds like a reasonable start to me. Is there any reason our kids should be consuming this stuff as a school lunch…which for many is the only meal they can count on every day?
Since it is Gavin Newsom who is behind this, does that suddenly make it more acceptable?
@John,
Is there any reason our kids shouldn’t be consuming this stuff as part of a school lunch, as long as it’s not the entire lunch every single day?
Given the lack of clinical trials, the gold standard of scientific research, why should we let schools feed kids any amount of the stuff on CA’s list of UP foods?
I take only a few milligrams of statins every day, and this tiny amount of medication has very beneficial effects. Why couldn’t a few milligrams of UPs have a very harmful effect.
Fact is, we don’t know. I prefer to err on the side of caution…especially when it comes to what our kids consume.
@John,
Since when were foods part of clinical trials? Foods are not medicine. Your attempt to analogize foods to statins is specious.
“Why couldn’t a few milligrams of UPs have a very harmful effect.”
Given the decades of history with processed foods (Cheerios, for example, first appeared 80 years ago), please explain how it would be possible for a few milligrams to have very harmful effects that nobody ever noticed. Take all the time you need.
Fact is, we know. You are of course free to avoid them, but don’t enlist the nanny state in that crusade.
Actually, we do not have decades of experience with all UPs. Many of those on the CA list are of recent fabrication. New ones are being fabricated all the time.
Cheerios are not simply representatative of ALL UPs. Just because something has been ingested or inhaled for centuries does not mean that it is not poisonous…think iron, or asbestos or, tobacco and pesticides. Should we have just ignored these substances because they are not medicine and consumed only in minute quantities?
IMO it would be gross negligence to blindly assume that the artificial substances on th CA list are simply “like Cheerios” and suitable for consumption by kids in school lunches. IMO supplements and herbal medicines, particularly over used ones like melatonin, deserve scrutiny. https://newsroom.heart.org/news/long-term-use-of-melatonin-supplements-to-support-sleep-may-have-negative-health-effects
@John,
“IMO supplements and herbal medicines, particularly over used ones like melatonin, deserve scrutiny.”
I’m fine with that. Food isn’t medicine. IMO, the phony conflation of supplements/medicines, asbestos, tobacco or pestacides with food deserves scrutiny.
“Cheerios are not simply representatative [sic] of ALL UPs.”
Indeed. But anyone who asserts that processed foods are dangerous needs to explain why they are more dangerous than Cheerios. Take all the time you need.
As for your melatonin link, it is highly speculative. The link itself acknowledges that no cause and effect can be proven.
John:
“Just because something has been ingested or inhaled for centuries does not mean that it is not poisonous. . . think iron, or asbestos or, tobacco and pesticides.”
All of these have been declared as dangerous. Perhaps, you have something which has not been declared dangerous when it really is such. A few drugs used on me are dangerous if used in abundance. Without them, I would be dead. Measured and used properly they can be life saving.
In some neighborhoods, daily fresh food can not be had daily or even available.. So what should they eat if not the canned and not so fresh version? If the groceries are to expensive and a fast-food burger is more readily available, should people be denied such?
McDonads often falls into the category of ultra-processed foods (UPFs), meaning ingredients are significantly altered from their original state with added flavors, colors, preservatives, and fillers, leading to items high in sugar, salt, and fat, linked to health issues, though McDonald’s highlights using real ingredients and offers some transparency.
McNuggets comes to mind.
UPFs are the bane of nutrition and they can be a substitute for what is not available due to politics by Herr Tru_p or proximity.
I’m not a big fan of empty calories foods, which is a lot of what Big Food companies peddle, particularly to kids. https://www.medicalnewstoday.com/articles/empty-calories
“Research from 2012 found that male adults ate an average of 923 empty calories per day. For females, the average intake of empty calories was 624 calories per day.
The added fats and sugars make these empty calories taste good, which can cause people to crave them.”
Kudos to California for prioritizing healthy school lunches instead of junk food. It’s entirely possible…just look to France for inspiration.

@John,
“I’m not a big fan of empty calories foods . . .”
Nor am I. I just don’t call them “poison.”
Easy-peezy. Cheerios don’t contain most of the additives listed on thr CA list. Salt and sugar are in low quantities.
https://www.cvs.com/shop/ingredients/cheerios-cereal-original-prodid-169905
As for not testing ingredients on th CA list, I oppose an “ignorance is bliss” policy.
@John,
LOL! Why, exactly, should we care about the CA list? Who appointed them gods of food? Are all foods that contain ingredients on the CA list ipso facto “dangerous?” By any definition, Cheerios are processed food. Decades of experience show that Cheerios are not dangerous. Please link to published evidence that processed foods, consumed in moderation, are dangerous. Take all the time you need.
Valorizing some recent ad hoc definition over 80 years of actual experience certainly qualifies as ignorance, blissful or not.
Very MAHA approach to the issue. Wanting actual information on the health effects is described as ‘ignorance’, acquiring a better understanding of the impacts will harm people and insisting that we rely on 80 years of uninformed rose colored memories is true science! IGNORE THE SCIEMCE, TRUST CHEERIOS! MAHA!
@Jay,
LOL!
Very MAHA approach to the issue. Citing actual information on health is described as ‘ignorance,” instead insisting that we ignore 80 years of experience in favor of conspiracy theory.
That’s the uninformed mantra of rose-colored RFK Jr. fiction: IGNORE THE SCIENCE, BLAME CHEERIOS. MAHA!
Heh!
