This review pertains to the 2019 edition of the book, not the 2011 original, which will not have had all of the same research.
We are told, by scientific consensus, to enjoy plenty of whole grains as part of our diet. So, what does cardiologist Dr. William Davis have against wheat?
Firstly, not all grains are interchangeable, and wheat—in particular, modern strains of wheat—cannot be described as the same as the wheat of times past.
While this book does touch on the gluten aspect (and Celiac disease), and notes that modern wheat has a much higher gluten content than older strains, most of this book is about other harms that wheat can do to us.
Dr. Davis explores and explains the metabolic implications of wheat’s unique properties on organs such as our pancreas, liver, heart, and brain.
The book does also have recipes and meal plans, though in this reviewer’s opinion they were a little superfluous. Wheat is not hard to cut out unless you are living in a food desert or are experiencing food poverty, in which case, those recipes and meal plans would also not help.
Bottom line: this book, filled with plenty of actual science, makes a strong case against wheat, and again, mostly for reasons other than its gluten content. You might want to cut yours down!

A Cold Shower A Day Keeps The Doctor Away?
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 Cold Shower A Day Keeps The Doctor Away?
This is Dutch extreme athlete Wim Hof, also known as “The Iceman”! He’s broken many world records mostly relating to the enduring the cold, for example:
- climbing Mount Kilimanjaro in shorts
- running a half-marathon above the Arctic Circle barefoot
- standing in a container completely covered with ice cubes for more than 112 minutes
You might not want to do yoga in your pyjamas on an iceberg, but you might like…
- better circulatory health
- reduced risk of stroke
- a boosted immune system
- healthier skin
- more energy and alertness
…and things like that. Wim Hof’s method is not just about extreme athletic achievements; most of what he does, the stuff that can benefit the rest of us, is much more prosaic.
The Wim Hof Method
For Wim Hof, three things are key:
- Breathing (See: Wim Hof Method Breathing Exercises)
- Commitment (See: How to Increase Willpower)
- Cold therapy (See: Benefits of Cold Therapy)
Today, we’re going to be focusing on the last one there.
What are the benefits of Cold Therapy?
Once upon a time, we didn’t have central heating, electric blankets, thermal underwear, and hot showers. In fact, once upon a time, we didn’t have houses or clothes. We used to be a lot more used to the elements! And while it’s all well and good to enjoy modern comforts, it has left our bodies lacking practice.
Practice at what? Most notably: vasodilation and vasoconstriction, in response to temperature changes. Either:
- vasodilation, because part of our body needs more blood to keep it warm and nourished, or
- vasoconstriction, because part of our body needs less blood running through it to get cooled down.
Switching between the two gives the blood vessels practice at doing it, and improves vascular muscle tone. If your body doesn’t get that practice, your blood vessels will be sluggish at making the change. This can cause circulation problems, which in turn have a big impact in many other areas of health, including:
- cardiovascular disease
- stroke risk
- mood instability
- nerve damage in extremities
On the flipside, if the blood vessels do get regular practice at dilating and constricting, you might enjoy lower risk of those things, and instead:
- improved immune response
- healthier skin
- better quality sleep
- more energy and alertness
- improved sexual performance/responsiveness
So, how to get that, without getting extreme?
As today’s title suggests, “a cold shower a day” is a great practice.
You don’t have to jump straight in, especially if you think your circulation and vascular responses might be a bit sluggish in the first instance. In fact, Wim Hof recommends:
- Week 1: Thirty seconds of cold water at the end of a warm shower each morning
- Week 2: One minute of cold water at the end of a warm shower each morning
- Week 3: A minute and a half of cold water at the end of a warm shower each morning
- Week 4: Two minutes of cold water at the end of a warm shower each morning
How cold is cold?
The benefits of cold exposure begin at around 16ºC / 60ºF, so in most places, water from the cold water mains is sufficiently cold.
As your body becomes more used to making the quick-change on a vascular level, the cold water will seem less shocking to your system. In other words, on day 30 it won’t hit you like it did on day one.
At that point, you can either continue with your two-minutes daily cold shower, and reap the benefits, or if you’re curious to push it further, that’s where ice baths come in!
Can anyone do it, or are any conditions contraindicated?
As ever, we’re a health and productivity newsletter, not doctors, let alone your doctors. Nothing here is medical advice. However, Wim Hof himself says:
❝Listen to your body, and never force the practices. We advise against doing Wim Hof Method if you are dealing with any of the following:
- Epilepsy
- High blood pressure
- Coronary heart disease
- A history of serious healthy issues like heart failure or stroke
- Pregnancy*
- Childhood*❞
*There is simply not enough science regarding the effects of cold exposure on people who are pregnant, or children. Obviously, we don’t expect this to be remedied anytime soon, because the study insitutions’ ethics boards would (rightly!) hold up the study.
As for the other conditions, and just generally if unsure, consult a doctor.
As you can see, this does mean that a limitation of Cold Therapy is that it appears to be far better as a preventative, since it helps guard against the very conditions that could otherwise become contraindications.
We haven’t peppered today’s main feature with study papers, partly because Wim Hof’s own website has kindly collated a collection of them (with links and summaries!) onto one page:

Cucumber vs Lychee – 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 cucumber to lychee, we picked the lychee.
Why?
In terms of macros, the lychee has more carbs and more fiber, but both are low glycemic index foods. Functionally a tie, though we could consider it a nominal win for cucumber.
In the category of vitamins, cucumber has more of vitamins A, B1, B5, and K, while lychee has more of vitamins B2, B3, B6, B9, C, E, and choline. In particular, cucumber has a lot more vitamin K and lychee has a lot more vitamin C. Nevertheless, in terms of overall vitamin coverage, lychee is the clear winner here.
Looking at minerals, cucumber has more calcium, magnesium, manganese, and zinc, while lychee has more copper (especially rich in this), iron, phosphorus, potassium, and selenium. Another clear win for lychee.
Both have an abundance of anti-inflammatory polyphenols, but we could find no strong argument for one being better than the other in this category, just different.
In short, both are fine options, but the more nutritionally dense is the lychee, so that’s our choice!

Your Simplest Life – by Lisa Turner
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 probably know how to declutter, and perhaps even do a “unnecessary financial expenditures” audit. So, what does this offer beyond that?
A large portion of this book focuses on keeping our general life in a state of “flow”, and strategies include:
- How to make sure you’re doing the right part of the 80:20 split on a daily basis
- Knowing when to switch tasks, and when not to
- Knowing how to plan time for tasks
- No more reckless optimism, but also without falling foul of Parkinson’s Law (i.e. work expands to fill the time allotted to it)
- Decluttering your head, too!
When it comes to managing life responsibilities in general, Turner is very attuned to generational differences… Including the different challenges faced by each generation, what’s more often expected of us, what we’re used to, and how we probably initially learned to do it (or not).
To this end, a lot of strategies are tailored with variations for each age group. Not often does an author take the time to address each part of their readership like that, and it’s really helpful that she does!
All in all, a great book for simplifying your daily life.

Rose Hips vs Blueberries – 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 rose hips to blueberries, we picked the rose hips.
Why?
Both of these fruits are abundant sources of antioxidants and other polyphenols, but one of them stands out for overall nutritional density:
In terms of macros, rose hips have about 2x the carbohydrates, and/but about 10x the fiber. That’s an easy calculation and a clear win for rose hips.
When it comes to vitamins, rose hips have a lot more of vitamins A, B2, B3, B5, B6, C, E, K, and choline. On the other hand, blueberries boast more of vitamins B1 and B9. That’s a 9:2 lead for rose hips, even before we consider rose hips’ much greater margins of difference (kicking off with 80x the vitamin A, for instance, and many multiples of many of the others).
In the category of minerals, rose hips have a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc. Meanwhile, blueberries are not higher in any minerals.
In short: as ever, enjoy both, but if you’re looking for nutritional density, there’s a clear winner here and it’s rose hips.

Which Comes First, Cardio or Weights? – by Alex Hutchinson
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 book of questions and answers, myths and busts, and in short, all things exercise.
It’s laid out as many micro-chapters with questions as headers. The explanations are clear and easy to understand, with several citations (of studies and other academic papers) per question.
While it’s quite comprehensive (weighing in at a hefty 300+ pages), it’s not the kind of book where one could just look up any given piece of information that one wants.
Its strength, rather, lies in pre-emptively arming the reader with knowledge, and correcting many commonly-believed myths. It can be read cover-to-cover, or just dipped into per what interests you (the table of contents lists all questions, so it’s easy to flip through).
Bottom line: if you’ve found the world of exercise a little confusing and would like it demystifying, this book will result in a lot of “Oooooh” moments.
Click here to check out Which Comes First, Cardio or Weights?, and know your stuff!
PS: the short answer to the titular question is “mix it up and keep it varied”

Dealing With Hearing Loss
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.
Hearing is important, not only for convenience, but also for cognitive health—as an inability to participate in what for most people is an important part of social life, has been shown to accelerate cognitive decline:
14 Powerful Strategies To Prevent Dementia ← one of them is looking after your hearing
To this end, we’ve written before about ways to retain (or at least slow the loss of) your hearing, here:
But, what if, despite our best efforts, your hearing is declining regardless, or is already impaired in some way?
Working with the hand we’ve been dealt
So, your hearing is bad and/or deteriorating. Assuming you’ve ruled out possibilities of fixing it, the next step is how to manage this new state of affairs.
One thing to seriously consider, sooner than you think you need to, is using hearing aids. This is because they will not only help you in the obvious practical way, but also, they will slow the associated decline of the parts of your brain that process the language you hear:
ACHIEVE study finds hearing aids cut cognitive decline by 48%
…and here’s the paper itself:
Furthermore, hearing aid use can significantly reduce all-cause mortality:
Your ears are not the only organs
Remember, today’s about dealing with hearing loss, not preventing it (for preventing it, see the second link we dropped up top).
With this in mind: do not underestimate the usefulness of learning to lipread.
Lipreading is not a panacea; it has its limitations:
- You can’t lipread an audio-only phonecall, or a podcast, or the radio
- You can’t lipread a video call if the video quality is poor
- You can’t lipread if someone is wearing a mask (as in many healthcare settings)
- You can’t lipread multiple people at once; you have to choose whose mouth to watch (or at least, you will miss the first word(s) each time while switching)
- You can’t lipread during sex if your/their face is somewhere else (may seem like a silly example, but actually communication can be important in sex, and the number of times this writer has had to say “Say again?” in intimate moments is ridiculous)
However, it can also make a huge difference the rest of the time, and can even be a superpower in times/places when other people’s hearing is nullified, such as a noisy environment, or a video call in which someone’s mic isn’t working.
The good news is, it’s really very easy to learn to lipread. There are many valid ways (often involving consciously memorizing mouth-shapes from charts, and then putting them together one by one to build a vocabulary), but this writer recommends a more organic, less effort-intensive approach:
- Choose a video of someone who speaks clearly, and for which video you already know what is being said (such as by using subtitles first, or a transcript, or perhaps the person is delivering a famous speech or reciting a poem that you know well, or it’s your favorite movie that you’ve watched many times).
- Now watch it with the sound off (assuming you do normally have some hearing; if you don’t, then you’re probably ahead of the game here) and just pay close attention to the lips. Do this on repeat; soon you’ll be able to “hear” the sounds as you see them made.
- Now choose a video of someone who speaks clearly, for which video you do not already know what is being said. You’ll probably only get parts of it at first; that’s ok.
- Now learn the rest of what they said in that video (by reading a transcript or such), and use it like you used the first video.
- Now repeat steps 3 and 4 until you are lipreading most people easily unless there is some clear obfuscation preventing you.
This process should not take long, as there are only about 44 phonemes (distinct sounds) in English, and once you’ve learned them, you’re set. If you speak more languages, those same 44 phonemes should cover most of most of them, but if not, just repeat the above process with the next language.
Remember, if you have at least some hearing, then most of the time your lipreading and your hearing are going to be working together, and neither will be as strong without the other—but if necessary, well-practised lipreading can indeed often stand in for hearing when hearing isn’t available.
A note on sign language:
Sign language is great, and cool, and useful. However, it’s only as useful as the people who know it, which means that it’s top-tier in the Deaf community (where people will dodge hearing-related cognitive decline entirely, because their social interaction is predominantly signed rather than spoken), and can be useful with close friends or family members who learn it (or at least learn some), but isn’t as useful in most of the wider world when people don’t know it. But if you do want to learn it, don’t let that hold you back—be the change you want to see!
Most of our readers are American, so here’s a good starting place for American Sign Language ← this is a list of mostly-free resources
