Cost of living: if you can’t afford as much fresh produce, are canned veggies or frozen fruit just as good?

The cost of living crisis is affecting how we spend our money. For many people, this means tightening the budget on the weekly supermarket shop.
One victim may be fresh fruit and vegetables. Data from the Australian Bureau of Statistics (ABS) suggests Australians were consuming fewer fruit and vegetables in 2022–23 than the year before.
The cost of living is likely compounding a problem that exists already – on the whole, Australians don’t eat enough fruit and vegetables. Australian dietary guidelines recommend people aged nine and older should consume two serves of fruit and five serves of vegetables each day for optimal health. But in 2022 the ABS reported only 4% of Australians met the recommendations for both fruit and vegetable consumption.
Fruit and vegetables are crucial for a healthy, balanced diet, providing a range of vitamins and minerals as well as fibre.
If you can’t afford as much fresh produce at the moment, there are other ways to ensure you still get the benefits of these food groups. You might even be able to increase your intake of fruit and vegetables.
Frozen
Fresh produce is often touted as being the most nutritious (think of the old adage “fresh is best”). But this is not necessarily true.
Nutrients can decline in transit from the paddock to your kitchen, and while the produce is stored in your fridge. Frozen vegetables may actually be higher in some nutrients such as vitamin C and E as they are snap frozen very close to the time of harvest. Variations in transport and storage can affect this slightly.
Minerals such as calcium, iron and magnesium stay at similar levels in frozen produce compared to fresh.
Another advantage to frozen vegetables and fruit is the potential to reduce food waste, as you can use only what you need at the time.
As well as buying frozen fruit and vegetables from the supermarket, you can freeze produce yourself at home if you have an oversupply from the garden, or when produce may be cheaper.
A quick blanching prior to freezing can improve the safety and quality of the produce. This is when food is briefly submerged in boiling water or steamed for a short time.
Frozen vegetables won’t be suitable for salads but can be eaten roasted or steamed and used for soups, stews, casseroles, curries, pies and quiches. Frozen fruits can be added to breakfast dishes (with cereal or youghurt) or used in cooking for fruit pies and cakes, for example.
Canned
Canned vegetables and fruit similarly often offer a cheaper alternative to fresh produce. They’re also very convenient to have on hand. The canning process is the preservation technique, so there’s no need to add any additional preservatives, including salt.
Due to the cooking process, levels of heat-sensitive nutrients such as vitamin C will decline a little compared to fresh produce. When you’re using canned vegetables in a hot dish, you can add them later in the cooking process to reduce the amount of nutrient loss.
To minimise waste, you can freeze the portion you don’t need.
Fermented
Fermentation has recently come into fashion, but it’s actually one of the oldest food processing and preservation techniques.
Fermentation largely retains the vitamins and minerals in fresh vegetables. But fermentation may also enhance the food’s nutritional profile by creating new nutrients and allowing existing ones to be absorbed more easily.
Further, fermented foods contain probiotics, which are beneficial for our gut microbiome.
5 other tips to get your fresh fix
Although alternatives to fresh such as canned or frozen fruit and vegetables are good substitutes, if you’re looking to get more fresh produce into your diet on a tight budget, here are some things you can do.
1. Buy in season
Based on supply and demand principles, buying local seasonal vegetables and fruit will always be cheaper than those that are imported out of season from other countries.
2. Don’t shun the ugly fruit and vegetables
Most supermarkets now sell “ugly” fruit and vegetables, that are not physically perfect in some way. This does not affect the levels of nutrients in them at all, or their taste.
3. Reduce waste
On average, an Australian household throws out A$2,000–$2,500 worth of food every year. Fruit, vegetables and bagged salad are the three of the top five foods thrown out in our homes. So properly managing fresh produce could help you save money (and benefit the environment).
To minimise waste, plan your meals and shopping ahead of time. And if you don’t think you’re going to get to eat the fruit and vegetables you have before they go off, freeze them.
4. Swap and share
There are many websites and apps which offer the opportunity to swap or even pick up free fresh produce if people have more than they need. Some local councils are also encouraging swaps on their websites, so dig around and see what you can find in your local area.
5. Gardening
Regardless of how small your garden is you can always plant produce in pots. Herbs, rocket, cherry tomatoes, chillies and strawberries all grow well. In the long run, these will offset some of your cost on fresh produce.
Plus, when you have put the effort in to grow your own produce, you are less likely to waste it.

When the Body Says No – by Dr. Gabor Maté
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.
We know that chronic stress is bad for us because of what it does to our cortisol levels, so what is the rest of this book about?
Dr. Gabor Maté is a medical doctor, heavily specialized in the impact of psychological trauma on long term physical health.
Here, he examies—as the subtitle promises—the connection between stress and disease. As it turns out, it’s not that simple.
We learn not just about the impact that stress has on our immune system (including increasing the risk of autoimmune disorders like rheumatoid arthritis), the cardiovascular system, and various other critical systems fo the body… But also:
- how environmental factors and destructive coping styles contribute to the onset of disease, and
- how traumatic events can warp people’s physical perception of pain
- how certain illnesses are associated with particular personality types.
This latter is not “astrology for doctors”, by the way. It has more to do with what coping strategies people are likely to employ, and thus what diseases become more likely to take hold.
The book has practical advice too, and it’s not just “reduce your stress”. Ideally, of course, indeed reduce your stress. But that’s a) obvious b) not always possible. Rather, Dr. Maté explains which coping strategies result in the least prevalence of disease.
In terms of writing style, the book is very much easy-reading, but be warned that (ironically) this isn’t exactly a feel-good book. There are lot of tragic stories in it. But, even those are very much well-worth reading.
Bottom line: if you (and/or a loved one) are suffering from stress, this book will give you the knowledge and understanding to minimize the harm that it will otherwise do.

Mythbusting Cookware Materials
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.
In Wednesday’s newsletter, we asked you what kind of cookware you mostly use, and got the above-depicted, below-described, set of responses:
- About 45% said stainless steel
- About 21% said cast iron
- About 15% said non-stick (e.g. Teflon)
- About 9% said enamel
- About 6% said aluminum
- And 1 person selected “something else”, but then commented to the contrary, writing “I use all of the above”
So, what does the science say about these options?
Stainless steel cookware is safe: True or False?
True! Assuming good quality and normal use, anyway. There really isn’t a lot to say about this, because it’s very unexciting. So long as it is what it is labelled as: there’s nothing coating it, nothing comes out of it unless you go to extremes*, and it’s easy to clean.
*If you cook for long durations at very high temperatures, it can leach nickel and chromium into food. What this means in practical terms: if you are using stainless steel to do deep-frying, then maybe stop that, and also consider going easy on deep-frying in general anyway, because obviously deep-frying is unhealthy for other reasons.
Per normal use, however: pretty much the only way (good quality) stainless steel cookware will harm you is if you touch it while it’s hot, or if it falls off a shelf onto your head.
That said, do watch out for cheap stainless steel cookware that can contain a lot of impurities, including heavy metals. Since you probably don’t have a mass spectrometer and/or chemistry lab at home to check for those impurities, your best guard here is simply to buy from a reputable brand with credible certifications.
Ceramic cookware is safe: True or False?
True… Most of the time! Ceramic pans usually have metal parts and a ceramic cooking surface coated with a very thin layer of silicon. Those metal parts will be as safe as the metals used, so if that’s stainless steel, you’re just as safe as the above. As for the silicon, it is famously inert and body-safe (which is why it’s used in body implants).
However: ceramic cookware that doesn’t have an obvious metal part and is marketed as being pure ceramic, will generally be sealed with some kind of glaze that can leach heavy metals contaminants into the food; here’s an example:
Lead toxicity from glazed ceramic cookware
Copper cookware is safe: True or False?
False! This is one we forgot to mention in the poll, as one doesn’t see a lot of it nowadays. The copper from copper pans can leach into food. Now, of course copper is an important mineral that we must get from our diet, but the amount of copper that that can leach into food from copper pans is far too much, and can induce copper toxicity.
In addition, copper cookware has been found to be, on average, highly contaminated with lead:
Non-stick cookware contaminates the food with microplastics: True or False?
True! If we were to discuss all the common non-stick contaminants here, this email would no longer fit (there’s a size limit before it gets clipped by most email services).
Suffice it to say: the non-stick coating, polytetrafluoroethylene, is itself a PFAS, that is to say, part of the category of chemicals considered environmental pollutants, and associated with a long list of health issues in humans (wherein the level of PFAS in our bloodstream is associated with higher incidence of many illnesses):
You may have noticed, of course, that the “non-stick” coating doesn’t stick very well to the pan, either, and will tend to come off over time, even if used carefully.
Also, any kind of wet cooking (e.g. saucepans, skillets, rice cooker inserts) will leach PFAS into the food. In contrast, a non-stick baking tray lined with baking paper (thus: a barrier between the tray and your food) is really not such an issue.
We wrote about PFAS before, so if you’d like a more readable pop-science article than the scientific paper above, then check out:
PFAS Exposure & Cancer: The Numbers Are High
Aluminum cookware contaminates the food with aluminum: True or False?
True! But not usually in sufficient quantities to induce aluminum toxicity, unless you are aluminum pans Georg who eats half a gram of aluminum per day, who is a statistical outlier and should not be counted.
That’s a silly example, but an actual number; the dose required for aluminum toxicity in blood is 100mg/L, and you have about 5 liters of blood.
Unless you are on kidney dialysis (because 95% of aluminum is excreted by the kidneys, and kidney dialysis solution can itself contain aluminum), you will excrete aluminum a lot faster than you can possibly absorb it from cookware. On the other hand, you can get too much of it from it being a permitted additive in foods and medications, for example if you are taking antacids they often have a lot of aluminum oxide in them—but that is outside the scope of today’s article.
However, aluminum may not be the real problem in aluminum pans:
❝In addition, aluminum (3.2 ± 0.25 to 4.64 ± 0.20 g/kg) and copper cookware (2.90 ± 0.12 g/kg) were highly contaminated with lead.
The time and pH-dependent study revealed that leaching of metals (Al, Pb, Ni, Cr, Cd, Cu, and Fe, etc.) into food was predominantly from anodized and non-anodized aluminum cookware.
More metal leaching was observed from new aluminum cookware compared to old. Acidic food was found to cause more metals to leach during cooking.❞
~ the same paper we cited when talking about copper
Cast iron cookware contaminates the food with iron: True or False?
True, but unlike with the other metals discussed, this is purely a positive, and indeed, it’s even recommended as a good way to fortify one’s diet with iron:
The only notable counterpoint we could find for this is if you have hemochromatosis, a disorder in which the body is too good at absorbing iron and holding onto it.
Thinking of getting some new cookware?
Here are some example products of high-quality safe materials on Amazon, but of course feel free to shop around:
Stainless Steel | Ceramic* | Cast Iron
*it says “non-stick” in the description, but don’t worry, it’s ceramic, not Teflon etc, and is safe
Bonus: rice cooker with stainless steel inner pot
Take care!

Sugar Blues – by William Dufty
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.
This is a “read it cover to cover” book. It charts the rise of sugar’s place in world diets in general and the American diet in particular, and draws many conclusions about the effect this has had on us.
This book will challenge you. Sometimes, it will change your mind. Sometimes, you’ll go “no, I’m sure that’s not right”, and you’ll go Googling. Either way, you’ll learn something.
And that, for us, is the most important measure of any informational book: did we gain something from it? In Sugar Blues, perhaps the single biggest “gain” for the reader is that it’s an eye-opener and a call-to-arms—the extent to which you heed that is up to you, but it sure is good to at least be familiar with the battlefield.

Get The Right Help For Your Pain
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 Much Does It Hurt?
Sometimes, a medical professional will ask us to “rate your pain on a scale of 1–10”.
It can be tempting to avoid rating one’s pain too highly, because if we say “10” then where can we go from there? There is always a way to make pain worse, after all.
But that kind of thinking, however logical, is folly—from a practical point of view. Instead of risking having to give an 11 later, you have now understated your level-10 pain as a “7” and the doctor thinks “ok, I’ll give Tylenol instead of morphine”.
A more useful scale
First, know this:
Zero is not “this is the lowest level of pain I get to”.
Zero is “no pain”.
As for the rest…
- My pain is hardly noticeable.
- I have a low level of pain; I am aware of my pain only when I pay attention to it.
- My pain bothers me, but I can ignore it most of the time.
- I am constantly aware of my pain, but can continue most activities.
- I think about my pain most of the time; I cannot do some of the activities I need to do each day because of the pain.
- I think about my pain all of the time; I give up many activities because of my pain.
- I am in pain all of the time; It keeps me from doing most activities.
- My pain is so severe that it is difficult to think of anything else. Talking and listening are difficult.
- My pain is all that I can think about; I can barely move or talk because of my pain.
- I am in bed and I can’t move due to my pain; I need someone to take me to the emergency room because of my pain.
10almonds tip: are you reading this on your phone? Screenshot the above, and keep it for when you need it!
One extra thing to bear in mind…
Medical staff will be more likely to believe a pain is being overstated, on a like-for-like basis, if you are a woman, or not white, or both.
There are some efforts to compensate for this:
A new government inquiry will examine women’s pain and treatment. How and why is it different?

Beating Toxic Positivity
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 To Get Your Brain On A More Positive Track (Without Toxic Positivity)
There have been many studies done regards optimism and health, and they generally come to the same conclusion: optimism is simply good for the health.
Here’s an example we’ve mentioned before, but it’s a good introduction to today’s main feature. It’s a longitudinal study, and it followed 121,700 women (what a sample size!) for eight years. It controlled for all kinds of other lifestyle factors (especially smoking, drinking, diet, and exercise habits, as well as pre-existing medical conditions), so this wasn’t a case of “people who are healthy are more optimistic as results. And, in the researchers’ own words…
❝We found strong and statistically significant associations of increasing levels of optimism with decreasing risks of mortality, including mortality due each major cause of death, such as cancer, heart disease, stroke, respiratory disease, and infection. Importantly, findings were maintained after close control for potential confounding factors, including sociodemographic characteristics and depression❞
Read: Optimism and Cause-Specific Mortality: A Prospective Cohort Study
And yet, toxic positivity can cause as many problems as it tries to fix.
What is toxic positivity?
- Toxic positivity is the well-meaning friend who says “I’m sure it’ll be ok” when you know full well it definitely will not.
- Toxic positivity is the allegorical frog-in-a-pan saying that the temperature rises due to climate change are gradual, so they’re nothing to worry about
- Toxic positivity is thinking that “good vibes” will outperform chemotherapy
Sometimes, a dose of realism is needed. So, can we do that and maintain a positive attitude?
The answer is: somewhat, yes! But first, a quick check-in:
❝I’m not a pessimist; I’m a realist!❞
~ every pessimist ever
To believe self-reports, the world is divided between optimists and realists. But how does your outlook measure up, really?
While like most free online tests, this is offered “as-is” with the usual caveats about not being a clinical diagnostic tool, this one actually has a fair amount of scientific weight behind it:
❝Empirical testing has indicated the validity of the Optimism Pessimism Instrument as published in the scientific journal Current Psychology: Research and Reviews.
The IDRlabs Optimism/Pessimism Test (IDR-OPT) was developed by IDRlabs. The IDR-OPT is based on the Optimism/Pessimism Instrument (OPI) developed by Dr. William Dember, Dr. Stephanie Martin, Dr. Mary Hummer, Dr. Steven Howe, and Dr. Richard Melton, at the University of Cincinnati.❞
Take This Short (1–2 mins) Test
How did you score? And what could you do to improve on that score?
First, it’s said that with a big enough “why”, one can overcome any “how”. So…
An attitude of gratitude
We know, we know, it’s very Oprah Winfrey. But also, it works. Take the time, ideally daily, to quickly list 3–5 things for which you feel grateful. Great or small, it can be anything from your spouse to your cup of coffee, provided you feel fortunate to have it.
How this works: our brains easily get stuck in loops, so it can help to nudge them into a more positive loop.
What about when we are treated unfairly? Are we supposed to be grateful?
Sometimes, our less positive emotions are necessary, to protect us and/or those around us, and to provide a motivational force. We can still maintain a positive attitude by noting the bad thing and some good, but watch out! Notice the difference:
- “How dare they take our healthcare away, but at least I’m not sick right now” (lasting impression: no action required)
- “At least I’m not sick right now, but how dare they take our healthcare away!” (lasting impression: action required)
It’s a well-known idea in neurolinguistic programming, that “but” negates whatever goes before it (think of “I’m sorry but”, or “I’m not racist but”, etc), so use it consciously and wisely, or else simply use “and” instead.
Cognitive reframing: problem, or opportunity?
Most problems can be opportunities, even if the problems themselves genuinely suck and are not intrinsically positive. A way of leveraging this can be replacing “I have to…” with “I get to…”.
This not only can reframe problems as opportunities, but also calls back to the gratitude idea.
- Instead of “I have to get my mammogram / prostate exam” (not generally considered fun activities), “I get to have the peace of mind of being free from cancer / I get to have the forewarning that will keep me safe”.
- Instead of “I have to go to work”, “I get to go to work” (many wish they were in your shoes!)
- Instead of “I have to rest”, “I get to rest”
When things are truly not great
Whether due to internal or external factors, whether you can control something or not, sometimes things are truly not great. The trick here is that in most contexts, one can replace negative talk, with verbally positive talk, no matter how dripping with scathing irony. You’ll still get to express the idea you wanted, but your brain will feel more positive and you’ll be in a positive loop rather than a negative one.
This, by the way, is the inverse of talking to a dog with a tone of voice that is completely the opposite of the meaning of the words. Whereas the dog will interpret the tone only, your brain will interpret the words only.
- You just spilled your drink over yourself at a social function? “Aren’t I the very model of grace and charm?”
- You made a costly mistake in your business dealings? “I am such a genius”
- You just got a diagnosis of a terrible disease? “Well, this is fabulous”
None of these things involve burying your head in the sand, in the manner of toxic positivity. You’ll still learn from your business mistake and correct it as best you can, or take appropriate action regards the disease, for example.
You’ll just feel better while you do it, and not get caught into a negative spiral that ruins your day, or even your next few months.
Sympathetic/Somatic Therapy:
Lastly, an easy one, leveraging the body’s tendency to get in sync with things around us:
For when you do just need a mood change, have an uplifting playlist available at the touch of a button. It’s hard to be consumed with counterproductive feelings to the tune of “Walking on Sunshine”!
Bonus tip: consider having the playlist start with something that is lyrically negative while musically upbeat. That way, your brain won’t resist it as antithetical to your mood, and by the second track, you’ll already be on your way to a better mood.

Why Telomeres Shorten, & What Can Be Done About It
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.
Telomeres are protective caps at the ends of our DNA, similar to the plastic tips on shoelaces (there’s a repeated “junk DNA” string, TTAGGG in humans, kept safe in a sheathe, which made of shelterin, a protein complex).
They prevent our genetic material from becoming damaged or tangled. However, each time a cell divides, telomeres get a little shorter because the copying process isn’t perfect (DNA polymerase can’t replicate everything inside the sheathe, because it is too well-protected).
So, how do we deal with this?
Lacing up for long life
An enzyme called telomerase (discovered as recently as 2009 by Nobel Prize-winning scientists Dr. Elizabeth Blackburn et al.) can rebuild telomeres. It has two main parts: one part1 that makes new DNA and another part2 that acts as a guide. Most cells don’t produce enough telomerase, so telomeres still tend to shrink over time.
1 TERT (Telomerase Reverse Transcriptase), which synthesizes telomeric DNA
2 TERC (Telomerase RNA Component), which serves as a templateWhen telomeres become too short, cells stop dividing. Some cells may enter a damaged state (e.g. senescent “zombie” cells) or die. In some cases, cells bypass this limit by reactivating telomerase, which can lead to cancer.
Studies on mice show that when telomerase is missing, they age more quickly and struggle to repair tissues. When telomerase is restored, aging effects are reversed. Human research also links short telomeres to age-related diseases like immune system decline and organ damage.
Researchers have already found some ways to slow aging by:
- Activating telomerase (e.g. with small molecules like TA-65).
- Gene therapy to transiently express telomerase.
- Stabilizing TERC RNA component to prevent degradation.
However, increasing telomerase too much could raise the risk of cancer. So, it’s a bit of a juggling act yet.
