In health terms, we are often about fighting aging here. But to be more specific, what we’re fighting in those cases is not truly aging itself, so much as age-related decline.
Karen Walrond makes a case that we’ve made from the very start of 10almonds (but she wrote a whole book about it), that there’s merit in looking at what we can and can’t control about aging, doing what we reasonably can, and embracing what we can’t.
And yes, embracing, not merely accepting. This is not a downer of a book; it’s a call to revolution. It asks us to be proud of our grey hairs, to see our smile-lines around our eyes as the sign of a lived-in body, and even to embrace some of the unavoidable “actual decline” things as part of the journey of life. Maybe we’re not as strong as we used to be and now need a grippety-doodah to open jars; not everyone gets to live long enough to experience that! How lucky we are.
Perhaps most importantly, she bids us be the change we want to see in the world, and inspire others with our choices and actions, and shake off ageist biases for good.
Bottom line: if you want to foster a better attitude to aging not only for yourself, but also those around you, then this is a top-tier book for that.

Fast Like A Girl – by Dr. Mindy Pelz
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.
A lot of information out there when it comes to intermittent fasting is very much centered on men in the 25–35 years age range. What about the rest of us?
Our physiological needs are not the same, and it’d be foolhardy to ignore that. But what things do still stand the same, and what things would benefit from a different approach in our cases?
Dr. Pelz has our back with this book packed with information based on the best science currently out there. She gives a general overview of fasting with full consideration to the fact that we the reader may well be female or over a certain age or both. In addition, the book offers:
- Metabolic switching (the “missing key to weight loss”)
- Building a fasting lifestyle (that works with your actual life, not just on paper)
- How to time fasting according to your menstrual cycle (if you don’t have a cycle, she has you covered too)
- How to break a fast—properly (and many other hacks/tips/tricks to make fasting so much easier)
Bottom line: if you want to do intermittent fasting and want to work with rather than against your body, then this book is a fine option.

‘Noisy’ autistic brains seem better at certain tasks. Here’s why neuroaffirmative research matters

Autism is a neurodevelopmental difference associated with specific experiences and characteristics.
For decades, autism research has focused on behavioural, cognitive, social and communication difficulties. These studies highlighted how autistic people face issues with everyday tasks that allistic (meaning non-autistic) people do not. Some difficulties may include recognising emotions or social cues.
But some research, including our own study, has explored specific advantages in autism. Studies have shown that in some cognitive tasks, autistic people perform better than allistic people. Autistic people may have greater success in identifying a simple shape embedded within a more complex design, arranging blocks of different shapes and colours, or spotting an object within a cluttered visual environment (similar to Where’s Wally?). Such enhanced performance has been recorded in babies as young as nine months who show emerging signs of autism.
How and why do autistic individuals do so well on these tasks? The answer may be surprising: more “neural noise”.
What is neural noise?
Generally, when you think of noise, you probably think of auditory noise, the ups and downs in the amplitude of sound frequencies we hear.
A similar thing happens in the brain with random fluctuations in neural activity. This is called neural noise.
This noise is always present, and comes on top of any brain activity caused by things we see, hear, smell and touch. This means that in the brain, an identical stimulus that is presented multiple times won’t cause exactly the same activity. Sometimes the brain is more active, sometimes less. In fact, even the response to a single stimulus or event will fluctuate continuously.
Neural noise in autism
There are many sources of neural noise in the brain. These include how the neurons become excited and calm again, changes in attention and arousal levels, and biochemical processes at the cellular level, among others. An allistic brain has mechanisms to manage and use this noise. For instance, cells in the hippocampus (the brain’s memory system) can make use of neural noise to enhance memory encoding and recall.
Evidence for high neural noise in autism can be seen in electroencephalography (EEG) recordings, where increased levels of neural fluctuations were observed in autistic children. This means their neural activity is less predictable, showing a wider range of activity (higher ups and downs) in response to the same stimulus.
In simple terms, if we imagine the EEG responses like a sound wave, we would expect to see small ups and downs (amplitude) in allistic brains each time they encounter a stimulus. But autistic brains seem to show bigger ups and downs, demonstrating greater amplitude of neural noise.
Many studies have linked this noisy autistic brain with cognitive, social and behavioural difficulties.
But could noise be a bonus?
The diagnosis of autism has a long clinical history. A shift from the medical to a more social model has also seen advocacy for it to be reframed as a difference, rather than a disorder or deficit. This change has also entered autism research. Neuroaffirming research can examine the uniqueness and strengths of neurodivergence.
Psychology and perception researcher David Simmons and colleagues at the University of Glasgow were the first to suggest that while high neural noise is generally a disadvantage in autism, it can sometimes provide benefits due to a phenomenon called stochastic resonance. This is where optimal amounts of noise can enhance performance. In line with this theory, high neural noise in the autistic brain might enhance performance for some cognitive tasks.
Our 2023 research explores this idea. We recruited participants from the general population and investigated their performance on letter-detection tasks. At the same time, we measured their level of autistic traits.
We performed two letter-detection experiments (one in a lab and one online) where participants had to identify a letter when displayed among background visual static of various intensities.
By using the static, we added additional visual noise to the neural noise already present in our participants’ brains. We hypothesised the visual noise would push participants with low internal brain noise (or low autistic traits) to perform better (as suggested by previous research on stochastic resonance). The more interesting prediction was that noise would not help individuals who already had a lot of brain noise (that is, those with high autistic traits), because their own neural noise already ensured optimal performance.
Indeed, one of our experiments showed people with high neural noise (high autistic traits) did not benefit from additional noise. Moreover, they showed superior performance (greater accuracy) relative to people with low neural noise when the added visual static was low. This suggests their own neural noise already caused a natural stochastic resonance effect, resulting in better performance.
It is important to note we did not include clinically diagnosed autistic participants, but overall, we showed the theory of enhanced performance due to stochastic resonance in autism has merits.
Why this is important?
Autistic people face ignorance, prejudice and discrimination that can harm wellbeing. Poor mental and physical health, reduced social connections and increased “camouflaging” of autistic traits are some of the negative impacts that autistic people face.
So, research underlining and investigating the strengths inherent in autism can help reduce stigma, allow autistic people to be themselves and acknowledge autistic people do not require “fixing”.
The autistic brain is different. It comes with limitations, but it also has its strengths.

How Not to Age – by Dr. Michael Greger
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.
First things first: it’s a great book, and it’s this reviewer’s favorite of Dr. Greger’s so far (for posterity: it’s just been published and this reviewer has just finished reading the copy she got on pre-order)
Unlike many popular physician authors, Dr. Greger doesn’t rehash a lot of old material, and instead favours prioritizing new material in each work. Where appropriate, he’ll send the reader to other books for more specific information (e.g: you want to know how to avoid premature death? Go read How Not To Die. You want to know how to lose weight? How Not To Diet. Etc).
In the category of new information, he has a lot to offer here. And with over 8,000 references, it’s information, not conjecture. On which note, we recommend the e-book version if that’s possible for you, for three reasons:
- It’s possible to just click the references and be taken straight to the cited paper itself online
- To try to keep the book’s size down, Dr. Greger has linked to other external resources too
- The only negative reviews on Amazon, so far, are people complaining that the print copy’s text is smaller than they’d like
For all its information-density (those 8,000+ references are packed into 600ish pages), the book is very readable even to a lay reader; the author is a very skilled writer.
As for the content, we can’t fit more than a few sentences here so forgive the brevity, but we’ll mention that he covers:
- Slowing 11 pathways of aging
- The optimal anti-aging regimen according to current best science
- Preserving function (specific individual aspects of aging, e.g. hearing, sight, cognitive function, sexual function, hair, bones, etc)
- “Dr. Greger’s Anti-Aging Eight”
In terms of “flavor” of anti-aging science, his approach can be summed up as: diet and lifestyle as foundation; specific supplements and interventions as cornerstones.
Bottom line: this is now the anti-aging book.

Anti-Inflammatory Diet 101 (What to Eat to Fight Inflammation)
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.
Chronic inflammation is a cause and/or exacerbating factor in very many diseases. Arthritis, diabetes, and heart disease are probably top of the list, but there are lots more where they came from. And, it’s good to avoid those things. So, how to eat to avoid inflammation?
Let food be thy medicine
The key things to keep in mind, the “guiding principles” are to prioritize whole, minimally-processed foods, and enjoy foods with plenty of antioxidants. Getting a healthy balance of omega fatty acids is also important, which for most people means getting more omega-3 and less omega-6.
Shopping list (foods to prioritize) includes:
- fruits and vegetables in a variety of colors (e.g. berries, leafy greens, beats)
- whole grains, going for the most fiber-rich options (e.g. quinoa, brown rice, oats)
- healthy fats (e.g. avocados, nuts, seeds)
- fatty fish (e.g. salmon, mackerel, sardines) ← don’t worry about this if you’re vegetarian/vegan though, as the previous category can already cover it
- herbs and spices (e.g. turmeric, garlic, ginger)
Noping list (foods to avoid) includes:
- refined carbohydrates
- highly processed and/or fried foods
- red meats and/or processed meats (yes, that does mean that organic grass-fed farmers’ pinky-promise-certified holistically-raised beef is also off the menu)
- dairy products, especially if unfermented
For more information on each of these, plus advice on transitioning away from an inflammatory diet, enjoy:

I’m iron deficient. Which supplements will work best for me and how should I take them?
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.
Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women are low in iron compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant.
The body needs iron to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration.
If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day?
Here are some tips to help you work out how, when and what iron supplement to take.
LittlePigPower/Shutterstock How do I pick the right iron supplement?
The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need.
The sweet spot is between 60-120 mg of elemental iron. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain.
Low iron can especially affect people during pregnancy and women who do a lot of sport. Kamil Macniak/Shutterstock In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). The iron salts you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%).
These formulations all work similarly, so your choice should come down to dose and cost.
Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency.
Should I take tablets or liquid formulas?
Iron contained within a tablet is just as well absorbed as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference.
The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term.
What should I eat with my iron supplement?
Research has shown you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone.
If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it.
Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other vitamin C-rich foods.
Taking your supplement alongside foods rich in vitamin C, like orange juice or kiwifruit, can help your body absorb the iron. Anete Lusina/Pexels On the other hand, tea, coffee and calcium all decrease the body’s ability to absorb iron. So you should try to limit these close to the time you take your supplement.
Should I take my supplement in the morning or evening?
The best time of day to take your supplement is in the morning. The body can absorb significantly more iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest.
Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can limit your ability to absorb it. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop.
Our research has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes).
My supplements are upsetting my stomach. What should I do?
If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily.
Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study has shown taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects.
Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success.
It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, iron can be toxic, so you don’t want to be consuming additional iron if your body doesn’t need it.
If you think you may be low on iron, talk to your GP to find out your best options.

The Worry Trick – by Dr. David Carbonell
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.
Worry is a time-sink that rarely does us any good, and often does us harm. Many books have been written on how to fight anxiety… That’s not what this book’s about.
Dr. David Carbonell, in contrast, encourages the reader to stop trying to avoid/resist anxiety, and instead, lean into it in a way that detoothes it.
He offers various ways of doing this, from scheduling time to worry, to substituting “what if…” with “let’s pretend…”, and guides the reader through exercises to bring about a sort of worry-desensitization.
The style throughout is very much pop-psychology and is very readable.
If the book has a weak point, it’s that it tends to focus on worrying less about unlikely outcomes, rather than tackling worry that occurs relating to outcomes that are likely, or even known in advance. However, some of the techniques will work for such also! That’s when Dr. Carbonell draws from Acceptance and Commitment Therapy (ACT).
Bottom line: if you would like to lose less time and energy to worrying, then this is a fine book for you.
