Food for Life – by Dr. Tim Spector

This book is, as the author puts it, “an eater’s guide to food and nutrition”. Rather than telling us what to eat or not eat, he provides an overview of what the latest science has to say about various foods, and leaves us to make our own informed decisions.
He also stands firmly by the “personalized nutrition” idea that he introduced in his previous book which we reviewed the other day, and gives advice on what tests we might like to perform.
The writing style is accessible, without shying away from reference to hard science. Dr. Spector provides lots of information about key chemicals, genes, gut bacteria, and more—as well as simply providing a very enjoyable read along the way.
Bottom line: if you’d like a much better idea of what food is (and isn’t) doing what, this book is an invaluable resource.

Caffeine: Cognitive Enhancer Or Brain-Wrecker?
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.
The Two Sides Of Caffeine
We asked you for your health-related opinions on caffeine itself, not necessarily the coffee, tea, energy drinks, etc that might contain it.
We have, by the way previously written about the health effects of coffee and tea specifically:
As for our question about caffeine itself, though, we got the above-depicted, below-described, set of results:
- About 59% said “caffeine is a safe stimulant and cognitive enhancer”
- About 31% said “caffeine is a moderately safe recreational drug”
- About 8% said “caffeine’s addictive properties make it de facto bad”
- One (1) person said “caffeine will leave you a trembling exhausted wreck”
But what does the science say?
Caffeine is addictive: True or False?
True, though one will find occasional academics quibbling the definition. Most of the studies into the mechanisms of caffeine addiction have been conducted on rats, but human studies exist too and caffeine is generally considered addictive for humans, for example:
See also:
Notwithstanding its addictive status, caffeine is otherwise safe: True or False?
True-ish, for most people. Some people with heart conditions or a hypersensitivity to caffeine may find it is not safe for them at all, and for the rest of us, the dose makes the poison. For example:
❝Can too much caffeine kill you? Although quite rare, caffeine can be fatal in cases of overdose; such circumstances are generally not applicable to healthy individuals who typically consume caffeine via beverages such as tea or coffee.❞
this paper, by the way, also includes a good example of academics quibbling the definition of addiction!
Caffeine is a cognitive enhancer: True or False?
True, but only in the case of occasional use. If you are using it all the time, your physiology will normalize it and you will require caffeine in order to function at your normal level. To attain higher than that, once addicted to caffeine, would now require something else.

Caffeine will leave you a trembling exhausted wreck: True or False?
True or False depending on usage:
- The famously moderate 3–5 cups per day will not, for most people, cause any such problems.
- Using/abusing it to make up for lost sleep (or some other source of fatigue, such as physical exhaustion from exertion), however, is much more likely to run into problems.
In the latter case, caffeine really is the “payday loan” of energy! It’ll give you an adrenal boost now (in return, you must suffer the adrenal dumping later, along with lost energy expended in the adrenaline surge), and also, the tiredness that you thought was gone, was just caffeine’s adenosine-blocking activities temporarily preventing you from being able to perceive the tiredness. So you’ll have to pay that back later, with interest, because of the extra time/exertion too.
Want to make caffeine a little more gentle on your system?
Taking l-theanine alongside caffeine can ameliorate some of caffeine’s less wonderful effects—and as a bonus, l-theanine has some nifty benefits of its own, too:

Kombucha vs Kimchi – Which is Healthier
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.
Our Verdict
When comparing kombucha to kimchi, we picked the kombucha.
Why?
While both are very respectable gut-healthy fermented products,
• the kombucha contains fermented tea, a little apple cider vinegar, and a little fiber
• the kimchi contains (after the vegetables) 810 mg sodium in that little tin, and despite the vegetables, no fiber.You may reasonably be surprised that they managed to take something that is made of mostly vegetables and ended up with no fiber without juicing it, but they did. Fermented vegetables are great for the healthy bacteria benefits (and are tasty too!), but the osmotic pressure due to the salt destroys the cell walls and thus the fiber.
Thus, we chose the kombucha that does the same job without delivering all that salt.
However! If you are comparing kombucha and kimchi out in the wilds of your local supermarket, do still check individual labels. It’s not uncommon, for example, for stores to sell pre-made kombucha that’s loaded with sugar.
About sugar and kombucha…
Sugar is required to make kombucha, to feed the yeast and helpful bacteria. However, there should be none of that sugar left (or only the tiniest trace amount) in the final product, because the yeast (and friends) consumed and metabolized it.
What some store brands do, however, is add in sugar afterwards, as they believe it improves the taste. This writer cannot imagine how, but that is their rationale in any case. Needless to say, it is not a healthy addition, and specifically, it’s bad for your gut, which (healthwise) is the whole point of drinking kombucha in the first place.

Buckwheat vs Oats – Which is Healthier?
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.
Our Verdict
When comparing buckwheat to oats, we picked the oats.
Why?
First of all, for any thinking about the health concerns sometimes associated with wheat: buckwheat is not a kind of wheat, nor is it even in the same family; it’s not a grain, but a flowering plant. Buckwheat is to wheat as a lionfish is to lions.
That said, while these are both excellent foods, one of them is so good it makes the other one look bad in comparison:
In terms of macros, oats have more carbs, but also more protein and more fiber.
When it comes to vitamins, a clear winner emerges: oats have more of vitamins B1, B2, B5, B6, and B9, while buckwheat is higher in vitamin K and choline.
In the category of minerals, things are even more pronounced: oats are higher in calcium, iron, magnesium, manganese, phosphorus, potassium, and zinc. On the other hand, buckwheat is higher in selenium.
All in all: as ever, enjoy both, but if you’re picking one, oats cannot be beaten.

Parents are increasingly saying their child is ‘dysregulated’. What does that actually mean?
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.
Welcome aboard the roller coaster of parenthood, where emotions run wild, tantrums reign supreme and love flows deep.
As children reach toddlerhood and beyond, parents adapt to manage their child’s big emotions and meltdowns. Parenting terminology has adapted too, with more parents describing their child as “dysregulated”.
But what does this actually mean?
More than an emotion
Emotional dysregulation refers to challenges a child faces in recognising and expressing emotions, and managing emotional reactions in social settings.
This may involve either suppressing emotions or displaying exaggerated and intense emotional responses that get in the way of the child doing what they want or need to do.
“Dysregulation” is more than just feeling an emotion. An emotion is a signal, or cue, that can give us important insights to ourselves and our preferences, desires and goals.
An emotionally dysregulated brain is overwhelmed and overloaded (often, with distressing emotions like frustration, disappointment and fear) and is ready to fight, flight or freeze.
Developing emotional regulation
Emotion regulation is a skill that develops across childhood and is influenced by factors such as the child’s temperament and the emotional environment in which they are raised.
In the stage of emotional development where emotion regulation is a primary goal (around 3–5 years old), children begin exploring their surroundings and asserting their desires more actively.
It’s typical for them to experience emotional dysregulation when their initiatives are thwarted or criticised, leading to occasional tantrums or outbursts.
A typically developing child will see these types of outbursts reduce as their cognitive abilities become more sophisticated, usually around the age they start school.
Express, don’t suppress
Expressing emotions in childhood is crucial for social and emotional development. It involves the ability to convey feelings verbally and through facial expressions and body language.
When children struggle with emotional expression, it can manifest in various ways, such as difficulty in being understood, flat facial expressions even in emotionally charged situations, challenges in forming close relationships, and indecisiveness.
Several factors, including anxiety, attention-deficit hyperactivity disorder (ADHD), autism, giftedness, rigidity and both mild and significant trauma experiences, can contribute to these issues.
Common mistakes parents can make is dismissing emotions, or distracting children away from how they feel.
These strategies don’t work and increase feelings of overwhelm. In the long term, they fail to equip children with the skills to identify, express and communicate their emotions, making them vulnerable to future emotional difficulties.
We need to help children move compassionately towards their difficulties, rather than away from them. Parents need to do this for themselves too.
Caregiving and skill modelling
Parents are responsible for creating an emotional climate that facilitates the development of emotion regulation skills.
Parents’ own modelling of emotion regulation when they feel distressed. The way they respond to the expression of emotions in their children, contributes to how children understand and regulate their own emotions.
Children are hardwired to be attuned to their caregivers’ emotions, moods, and coping as this is integral to their survival. In fact, their biggest threat to a child is their caregiver not being OK.
Unsafe, unpredictable, or chaotic home environments rarely give children exposure to healthy emotion expression and regulation. Children who go through maltreatment have a harder time controlling their emotions, needing more brainpower for tasks that involve managing feelings. This struggle could lead to more problems with emotions later on, like feeling anxious and hypervigilant to potential threats.
Recognising and addressing these challenges early on is essential for supporting children’s emotional wellbeing and development.
A dysregulated brain and body
When kids enter “fight or flight” mode, they often struggle to cope or listen to reason. When children experience acute stress, they may respond instinctively without pausing to consider strategies or logic.
If your child is in fight mode, you might observe behaviours such as crying , clenching fists or jaw, kicking, punching, biting, swearing, spitting or screaming.
In flight mode, they may appear restless, have darting eyes, exhibit excessive fidgeting, breathe rapidly, or try to run away.
A shut-down response may look like fainting or a panic attack.
When a child feels threatened, their brain’s frontal lobe, responsible for rational thinking and problem-solving, essentially goes offline.
This happens when the amygdala, the brain’s alarm system, sends out a false alarm, triggering the survival instinct.
In this state, a child may not be able to access higher functions like reasoning or decision-making.
While our instinct might be to immediately fix the problem, staying present with our child during these moments is more effective. It’s about providing support and understanding until they feel safe enough to engage their higher brain functions again.
Reframe your thinking so you see your child as having a problem – not being the problem.
Tips for parents
Take turns discussing the highs and lows of the day at meal times. This is a chance for you to be curious, acknowledge and label feelings, and model that you, too, experience a range of emotions that require you to put into practice skills to cope and has shown evidence in numerous physical, social-emotional, academic and behavioural benefits.
Spending even small amounts (five minutes a day!) of quality one-on-one time with your child is an investment in your child’s emotional wellbeing. Let them pick the activity, do your best to follow their lead, and try to notice and comment on the things they do well, like creative ideas, persevering when things are difficult, and being gentle or kind.
Take a tip from parents of children with neurodiversity: learn about your unique child. Approaching your child’s emotions, temperament, and behaviours with curiosity can help you to help them develop emotion regulation skills.
When to get help
If emotion dysregulation is a persistent issue that is getting in the way of your child feeling happy, calm, or confident – or interfering with learning or important relationships with family members or peers – talk to their GP about engaging with a mental health professional.
Many families have found parenting programs helpful in creating a climate where emotions can be safely expressed and shared.
Remember, you can’t pour from an empty cup. Parenting requires you to be your best self and tend to your needs first to see your child flourish.

Owning Your Weight – by Henri Marcoux
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 diet books—which this isn’t—presuppose that the reader wants to lose weight, and varyingly encourage and shame the reader into trying to do so.
Dr. Henri Marcoux takes a completely different approach.
He starts by assuming we are—whether consciously or not—the weight we want to be, and looks at the various physical and psychological factors that influence us to such. Ranging from food poverty to eating our feelings to social factors and more, he bids us examine our relationship with food and eating—not just in the sense of mindful eating, but from multiple scientific angles too.
From this, Dr. Marcoux gives us questions and suggestions to ensure that our relationship with food and eating is what we want it to be, for us.
Much of the latter part of the book covers not just how to go about the requisite lifestyle changes… But also how to implement things in a way that sticks, and is a genuine pleasure to implement. If this sounds over-the-top, the truth is that it’s just because it honestly is a lower-stress way of living.
Bottom line: if you want to gain or lose weight, there’s a good chance this book will help you. If you want to be happier and healthier at the weight you are, there’s a good chance this book will help you with that, too.

It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I think the heart may be an issue for lots of us. I know it is for me due to AFib. When I’m in my training zone like on a treadmill, I’m usually around 110 to 120. But there are occasionally times when I’m at 140 or 150. How dangerous is that? If I use that formula of 180 minus age, thats 103. I get nothing from that. My resting heart rate is in the 50 to 60 range.❞
First, for safety, let us draw attention to our medical disclaimer at the bottom of each email, and also specifically note that we are not cardiologists here, let alone your cardiologist. There’s a lot we can’t know or advise about. However, as general rules of thumb:
For people without serious health conditions, it is considered good and healthful for one’s heart rate to double (from its resting rate) during exercise, with even more than 2.5x resting rate being nothing more than a good cardio workout.
As for “180 minus age” (presuming you mean: to calculate the safe maximum heart rate), more common (and used by the American Heart Association) is 220 minus age. In your case, that’d give 143.
Having atrial fibrillation may change this however, and we can’t offer medical advice.
We can point to this AHA “AFib Resources For Patients and Professionals”, including this handy FAQ sheet which says:
“Am I able to exercise?” / “Yes, as long as you’re cleared by your doctor, you can perform normal activities of daily living that you can tolerate” (accompanied by a little graphic of a person using an exercise bike)
You personally probably know this already, of course, but it’s quite an extensive collection of resources, so we thought we’d include it.
It’s certainly a good idea for everyone to be aware of their healthy heart rate ranges, regardless of having a known heart condition or not, though!

❝Interesting, but… Did you know spinach is high in oxylates? Some people are sensitive and can cause increased inflammation, joint pain or even kidney stones. Moderation is key. My sister and I like to eat healthy but found out by experience that too much spinach salad caused us joint and other aches.❞
It’s certainly good to be mindful of such things! For most people, a daily serving of spinach shouldn’t cause ill effects, and certainly there are other greens to eat.
We wondered whether there was a way to reduce the oxalate content, and we found:
How to Reduce Oxalic Acid in Spinach: Neutralizing Oxalates
…which led us this product on Amazon:
Nephure Oxalate Reducing Enzyme, Low Oxalate Diet Support
We wondered what “nephure” was, and whether it could be trusted, and came across this “Supplement Police” article about it:
Nephure Review – Oxalate Reducing Enzyme Powder Health Benefits?
…which honestly, seems to have been written as a paid advertisement. But! It did reference a study, which we were able to look up, and find:
In vitro and in vivo safety evaluation of Nephure™
…which seems to indicate that it was safe (for rats) in all the ways that they checked. They did not, however, check whether it actually reduced oxalate content in spinach or any other food.
The authors did declare a conflict of interest, in that they had a financial relationship with the sponsor of the study, Captozyme Inc.
All in all, it may be better to just have kale instead of spinach:
