How Processed Is The Food You Buy, Really?

Ultraprocessed foods are a) ubiquitous in industrialized nations b) generally not fabulous for the health. See for example:
- Eat To Beat Cancer ← skipping the ultraprocessed foods is one main point
- What To Leave Off Your Table (To Stay Off This Surgeon’s) ← have a guess
Abstaining from ultraprocessed food can also be difficult psychologically, because they are generally engineered specifically to trigger certain physiological responses, often with their combination of sweet and/or salty flavors with simple carbohydrates that will zip straight into one’s veins and feel immediately rewarding, even if there is a health price to pay later.
And worse, being habituated to ultraprocessed food can make unprocessed or minimally-processed food seem less appealing:
What causes food cravings? And what can we do about them?
Fortunately, we can reverse this, and once we get habituated to unprocessed or minimally-processed food, the ultraprocessed will start to seem like not-food to us. You will wonder: how did I ever eat that crap?
Now, one other thing to bear in mind:
There is a scale of “badness”
You might recall this article:
Not all ultra-processed foods are bad for your health, whatever you might have heard
For example, Reese’s confectionary and Huel nutrition powder are both ultra-processed, but one is definitely better than the other.
See also: Are plant-based burgers really bad for your heart? Here’s what’s behind the scary headlines
Some comparisons are obvious; others, not so much. So, how to tell the difference?
The “True Food” Scale
A large study analyzed ingredient lists, nutrition facts, and prices of over 50,000 food items from Target, Whole Foods, and Walmart. Using a rigorous statistical method, they assigned processing scores and compiled data into a giant database, with results published publicly.
You can find the study here:
Prevalence of processed foods in major US grocery stores
That in and of itself doesn’t tell a lot that’s useful to the consumer, because the paper itself does not have all of the data from all 50,000 food items, just the aggregate results, trends, implications for public health, and suggestions for public health policy.
However, what does tell a lot, is the public face of the database itself, which you can browse for free, and look up your regular shopping items, if you are wondering “are these textured soy pieces basically a step away from soy beans, or a frankenfood that will murder me in my sleep?”
How it works: it examines each food, its listed ingredients, and what is known about the processedness of such ingredients. It also draws a distinction between ingredients and additives, rendering the entire process of the production of the food into an “ingredient tree”, showing what was added to what along the way. Minimally-processed foods will have barely an ingredient sapling, while ultraprocessed foods will have an ingredient tree whose branches can barely be counted, they are so numerous. It’s not just about the number of ingredients though; it’s about the processes that each underwent.
How it represents this data: you can look at the food in the database, and it’ll tell you the ingredients and nutritional facts (which you probably knew already; it’s written on the packaging), and then show you how processed it is, and then ranking that against all other foods in the database of the same kind.
So for example, if you are looking at a pizza (have you ever noticed how some are marketed with bright flashy colors, and others in natural tones to suggest minimal processing? This is marketing, not reliable information! Sometimes the product that looks healthier, isn’t!), then it’ll give it a score reflecting how it ranks compared to all other pizze in the database. This number is out of a hundred, and it reflects the percentile into which it falls.
So for example, if the score your pizza gets is 47, then that means that if you looked at it next to 99 others, on average your pizza would would rank better than 46 of them and worse than 53 of them.
In other words, the lower the score, the less processed it is on the whole.
Here’s a side-by-side example of two cakes, one of which got a score of 3, and the other got a score of 61:
Mini No Sugar Added Cheesecake vs EDWARDS Desserts Original Whipped Cheesecake

❝Loved the info on nuts; of course I always eat pecans, which didn’t make the list of healthy nuts!❞
Dear subscriber, pardon the paraphrase of your comment—somehow it got deleted and now exists only in this writer’s memory. However, to address it:
Pecans are great too! We can’t include everything in every article (indeed, we got another feedback the same day saying the article was too long), but we love when you come to us with stuff for us to look at and write about (seriously, writer here: the more you ask, the easier it makes my job), so let’s talk pecans for a moment:
Pecans would have been number six on our list if we’d have written more!
Like many nuts, they’ve an abundance of healthy fats, fiber, vitamins, and minerals.
They’re particularly good for zinc, which is vital for immune function, healing (including normal recovery after normal exercise), and DNA synthesis (so: anti-aging).
Pecans are also great for reducing LDL (“bad” cholesterol) and triglycerides (which are also bad for heart health); check it out:

Lemon Balm For Stressful Times And More
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Balm For The Mind: In More Ways Than One!
Lemon balm(Melissa officinalis) is quite unrelated to lemons, and is actually a closer relative to mint. It does have a lemony fragrance, though!
You’ll find it in a lot of relaxing/sleepy preparations, so…
What does the science say?
Relaxation
Lemon balm has indeed been found to be a potent anti-stress herb. Laboratories that need to test anything to do with stress generally create that stress in one of two main ways:
- If it’s not humans: a forced swimming test that’s a lot like waterboarding
- If it is humans: cognitive tests completed under time-pressure while multitasking
Consequently, studies that have set out to examine lemon balm’s anti-stress potential in humans, have often ended up also highlighting its potential as a cognitive enhancer, like this one in which…
❝Both active lemon balm treatments were generally associated with improvements in mood and/or cognitive performance❞
~ Dr. Anastasia Ossoukhova et al.
Read in full: Anti-Stress Effects of Lemon Balm-Containing Foods
And this one, which found…
❝The results showed that the 600-mg dose of Melissa ameliorated the negative mood effects of the DISS, with significantly increased self-ratings of calmness and reduced self-ratings of alertness.
In addition, a significant increase in the speed of mathematical processing, with no reduction in accuracy, was observed after ingestion of the 300-mg dose.❞
The appropriately named “DISS” is the Defined Intensity Stress Simulation we talked about.
Sleep
There’s a lot less research for lemon balm’s properties in this regard than for stress/anxiety, and it’s probably because sleep studies are much more expensive than stress studies.
It’s not for a lack of popular academic interest—for example, typing “Melissa officinalis” into PubMed (the vast library of studies we often cite from) autosuggests “Melissa officinalis sleep”. But alas, autosuggestions do not Randomized Controlled Trials make.
There are some, but they’re often small, old, and combined with other things, like this one:
This is interesting, because generally speaking there is little to no evidence that valerian actually helps sleep, so if this mixture worked, we might reasonably assume it was because of the lemon balm—but there’s an outside chance it could be that it only works in the presence of valerian (unlikely, but in science we must consider all possibilities).
Beyond that, we just have meta-reviews to work from, like this one that noted:
❝M. officinalis contains several phytochemicals such as phenolic acids, flavonoids, terpenoids, and many others at the basis of its pharmacological activities. Indeed, the plant can have antioxidant, anti-inflammatory, antispasmodic, antimicrobial, neuroprotective, nephroprotective, antinociceptive effects.
Given its consolidated use, M. officinalis has also been experimented with clinical settings, demonstrating interesting properties against different human diseases, such as anxiety, sleeping difficulties, palpitation, hypertension, depression, dementia, infantile colic, bruxism, metabolic problems, Alzheimer’s disease, and sexual disorders. ❞
You see why we don’t try to cover everything here, by the way!
But if you want to read this one in full, you can, at:

Is it safe?
Lemon balm is generally recognized as safe, and/but please check with your doctor/pharmacist in case of any contraindications due to medicines you may be on or conditions you may have.

The 9 “Healthy” Hair Habits That Are Damaging Your Hair
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
How many do you do?
Don’t sabotage your hair
The 9 habits to ditch are:
- Unsafe ponytails: wearing a ponytail in the same spot every day concentrates friction and tension on already fragile crown and upper-mid hair, leading to breakage; frequently changing the height and keeping the tie loose spreads stress and reduces damage.
- Fake heat protectants: many products labeled as heat protection do not actually shield hair from high temperatures, giving false confidence and allowing damage; real protection requires a dedicated heat protectant layered separately from a leave-in conditioner.
- Damaging detangling tools: wide-tooth combs are rigid and tend to catch and yank through knots, snapping fine strands; flexible detangling brushes bend around tangles, separate strands, and preserve length.
- Dirty tools and residue: brushes and hot tools quietly accumulate oil, product buildup, and skin flakes, which get transferred back into freshly washed hair; regularly cleaning tools prevents hair from looking greasy too quickly and preserves wash-day results.
- Air-drying when heat is needed: air-drying without heat leaves the cuticle rough and lifted, which looks dull and attracts oil and buildup faster; controlled heat smooths the cuticle, increases shine, and helps styles last longer when used properly.
- Wrong product order: applying products out of sequence causes them to block each other and produce inconsistent results; a clear order—leave-in first, styling next, heat protection on dry hair, and oil last—lets each step do its job.
- Uncontrolled blow-drying: blasting air without tension is effectively air-drying with a brush in your hand; maintaining tension and directing heat down the hair shaft seals the cuticle and creates a smooth, reflective finish.
- Conditioning soaking-wet hair: applying conditioner to dripping-wet hair prevents it from attaching properly to the hair shaft, wasting product and limiting hydration; gently squeezing out excess water first allows conditioner to penetrate and work effectively.
- Being haphazard about haircare: these issues are not about effort or discipline but about subtle technique errors; correcting them consistently leads to longer-lasting styles, better shine, and healthier-looking hair over time.

AI: The Doctor That Never Tires?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
AI: The Doctor That Never Tires?
We asked you for your opinion on the use of Artificial Intelligence (AI) in healthcare, and got the above-depicted, below-described set of results:
- A little over half of respondents to the poll voted for “It speeds up research, and is more methodical about diagnosis, so it’s at least a good extra tool”
- A quarter of respondents voted for “I’m on the fence—it seems to make no more nor less mistakes than human doctors do”
- A little under a fifth of respondents voted for “AI is less prone to fatigue/bias than human doctors, making it an essential new tech”
- Three respondents voted for “AI is a step too far in medical technology, and we’re not ready for it”
Writer’s note: I’m a professional writer (you’d never have guessed, right?) and, apparently, I really did write “no more nor less mistakes”, despite the correct grammar being “no more nor fewer mistakes”. Now, I know this, and in fact, people getting less/fewer wrong is a pet hate of mine. Nevertheless, I erred.
Yet, now that I’m writing this out in my usual software, and not directly into the poll-generation software, my (AI!) grammar/style-checker is highlighting the error for me.
Now, an AI could not do my job. ChatGPT would try, and fail miserably. But can technology help me do mine better? Absolutely!
And still, I dismiss a lot of the AI’s suggestions, because I know my field and can make informed choices. I don’t follow it blindly, and I think that’s key.
AI is less prone to fatigue/bias than human doctors, making it an essential new tech: True or False?
True—with one caveat.
First, a quick anecdote from a subscriber who selected this option in the poll:
❝As long as it receives the same data inputs as my doctor (ie my entire medical history), I can see it providing a much more personalised service than my human doctor who is always forgetting what I have told him. I’m also concerned that my doctor may be depressed – not an ailment that ought to affect AI! I recently asked my newly qualified doctor goddaughter whether she would prefer to be treated by a human or AI doctor. No contest, she said – she’d go with AI. Her argument was that human doctors leap to conclusions, rather than properly weighing all the evidence – meaning AI, as long as it receives the same inputs, will be much more reliable❞
Now, an anecdote is not data, so what does the science say?
Well… It says the same:
❝Of 6695 responding physicians in active practice, 6586 provided information on the areas of interest: 3574 (54.3%) reported symptoms of burnout, 2163 (32.8%) reported excessive fatigue, and 427 (6.5%) reported recent suicidal ideation, with 255 of 6563 (3.9%) reporting a poor or failing patient safety grade in their primary work area and 691 of 6586 (10.5%) reporting a major medical error in the prior 3 months. Physicians reporting errors were more likely to have symptoms of burnout (77.6% vs 51.5%; P<.001), fatigue (46.6% vs 31.2%; P<.001), and recent suicidal ideation (12.7% vs 5.8%; P<.001).❞
See the damning report for yourself: Physician Burnout, Well-being, and Work Unit Safety Grades in Relationship to Reported Medical Errors
AI, of course, does not suffer from burnout, fatigue, or suicidal ideation.
So, what was the caveat?
The caveat is about bias. Humans are biased, and that goes for medical practitioners just the same. AI’s machine learning is based on source data, and the source data comes from humans, who are biased.
See: Bias and Discrimination in AI: A Cross-Disciplinary Perspective
So, AI can perpetuate human biases and doesn’t have a special extra strength in this regard.
The lack of burnout, fatigue, and suicidal ideation, however, make a big difference.
AI speeds up research, and is more methodical about diagnosis: True or False?
True! AI is getting more and more efficient at this, and as has been pointed out, doesn’t make errors due to fatigue, and often comes to accurate conclusions near-instantaneously. To give just one example:
❝Deep learning algorithms achieved better diagnostic performance than a panel of 11 pathologists participating in a simulation exercise designed to mimic routine pathology workflow; algorithm performance was comparable with an expert pathologist interpreting whole-slide images without time constraints. The area under the curve was 0.994 (best algorithm) vs 0.884 (best pathologist).❞
About that “getting more and more efficient at this”; it’s in the nature of machine learning that every new piece of data improves the neural net being used. So long as it is getting fed new data, which it can process at rate far exceeding humans’ abilities, it will always be constantly improving.
AI makes no more nor
lessfewer mistakes than humans do: True or False?False! AI makes fewer, now. This study is from 2021, and it’s only improved since then:
❝Professionals only came to the same conclusions [as each other] approximately 75 per cent of the time. More importantly, machine learning produced fewer decision-making errors than did all the professionals❞
See: AI can make better clinical decisions than humans: study
All that said, we’re not quite at Star Trek levels of “AI can do a human’s job entirely” just yet:
BMJ | Artificial intelligence versus clinicians: pros and cons
To summarize: medical AI is a powerful tool that:
- Makes healthcare more accessible
- Speeds up diagnosis
- Reduces human error
…and yet, for now at least, still requires human oversights, checks and balances.
Essentially: it’s not really about humans vs machines at all. It’s about humans and machines giving each other information, and catching any mistakes made by the other. That way, humans can make more informed decisions, and still keep a “hand on the wheel”.

Tooth-Whitening That’s Safe For Your Teeth?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
No question/request too big or small 😎
❝Is there any way of whitening teeth that works and isn’t harming the teeth or gums?❞
The short answer is “yes”!
A slightly longer answer “yes, but…”
First, let’s pro/con the most common options:
Professional in-office whitening:
- pros: fastest results, most noticeable whitening, generally safest
- cons: most expensive option, can cause temporary tooth sensitivity (because they’re still usually using peroxides etc, just, more carefully than you likely can)
Dentist-prescribed take-home kits:
- pros: strong results, longer-lasting than over-the-counter options
- cons: slower than in-office treatment, requires consistent use, increased risk of sensitivity, almost certainly will harm gums
Over-the-counter whitening kits:
- pros: cheaper than dentist options, moderate effectiveness, more convenient than prescriptions or in-office treatments
- cons: weaker results, potential for poor fit and gum irritation, inconsistent outcomes, quite a fuss to have to do it
Whitening pens / paint-on gels:
- pros: portable, convenient for touch-ups, low cost
- cons: very limited effectiveness, uneven coverage, short contact time reduces results, likely to harm gums
Whitening toothpaste:
- pros: cheapest option, easy to incorporate into routine, helps remove surface stains
- cons: minimal actual whitening (mostly surface-level), doesn’t change tooth color deeply
Home remedies (baking soda, charcoal, lemon, etc):
- pros: low cost, very accessible
- cons: little to no proven whitening effect, anything acidic will damage the enamel (you are putting an acid on a base, that’s not going to go well!), others are likely to inflame the gums and/or erode the enamel by indiscriminate abrasive action
Whitening mouthwash:
- pros: easy to use, adds minor stain prevention
- cons: very weak effect due to short contact time, mainly maintenance rather than active whitening
Now let’s narrow those down
Let’s throw out the home remedies, the pens/gels, and the OTC kits.
This brings us down to:
- Professional treatments / treatments prescribed by your dentist
- Whitening toothpaste (not very effective, but unlike most things on the list, not harmful)
- Whitening mouthwash (might as well)
There are also options that aren’t so common, such as: Professional-Style Dental Cleaning At Home?, which methods are safe and effective if and only if you do them correctly. In short, if you’re not confident scraping plaque off your teeth, for example, don’t do it. If any any doubt whatsoever, leave those medieval-looking implements aside, and see your dentist instead.
Hollywood’s most “perfect” whites would be nothing without the gums holding them in place. So, it may be a good idea to set aside the cosmetic whitening products that often harm gums (anything containing bleach / hydrogen peroxide, is generally a bad idea), and instead focus on your gums.
As for avoiding gum disease (periodontitis)?
❝In conclusion, periodontitis might enhance the association of biological aging with all-cause mortality in middle-aged and older adults.
Hence, maintaining and enhancing periodontal health is expected to become an intervention to slow aging and extend life span.❞
Source: Does Periodontitis Affect the Association of Biological Aging with Mortality?
To look after the whole, you have to take care of the parts. So, with this in mind:

- How To Regrow Receding Gums
- Make Your Saliva Better For Your Teeth
Restore your enamel
“When it’s gone, it’s gone” is the common belief when it comes to tooth enamel. Nevertheless, there are such things as hydroxyapatite toothpaste which is not only as pathogen-killing as fluoride, but also has the added bonus of being based on one of the main minerals our teeth are made of (hydroxyapatite is a calcium phosphate compound), so it does aid in rebuilding,
There are pros and cons to both, by the way: Fluoride Toothpaste vs Non-Fluoride Toothpaste – Which is Healthier? ← with interesting numbers on the toxicity of each!
In that comparison (we compared fluoride to hydroxyapatite) we picked the fluoride on the basis of “they both do the job equally well, and they’re both very safe, but technically everything has a toxicity level, and fluoride’s is the relatively safest of these two very safe products”.
However, that’s assuming for the general job of “keeping teeth healthy”. If your teeth need remineralizing, hydroxyapatite will better promote that.

Not only does it clean the teeth as well as or better than traditional brushing, but also it changes the composition of saliva to improve the oral microbiome, effectively turning your saliva into a biological mouthwash that kills unwanted microbes and is comfortable for the ones that should be there.
