❝I was wondering whether I should be using a body scrub in the shower, rather than just soap. What should guide me in the choice of a body scrub, and are there any risks to be aware of?❞
Body scrubs are great for giving skin a healthy glow, but are best used sparingly—over-exfoliation leads to the opposite effect (unhappy skin, premature skin aging, etc).
As for contents:
- microplastics are now banned in most places, but you might want to check any products (and their containers!) are BPA-free, pthalate free, etc.
- fragrances in body scrubs are usually a bad idea, and many essential oils have been shown to be endocrine-disruptors, which you do not want:
About the microplastics, harmful artificial chemicals in general, and what constitutes “etc”:
About the fragrances’ (including “natural” essential oils’) endocrine-disrupting shenanigans:

So, what might you want to use instead?
If you’re feeling adventurous, you might like to try treating yourself to a pineapple-based mask instead (a muslin cloth soaked in pineapple juice will work just fine; please don’t waterboard yourself though), as the bromelain enzymes (found very generously in pineapple juice) break down dead cells without the need for scrubbing.
Another option is a homemade salt- or sugar-scrub. Put your salt or sugar into a jar, add enough warm water to cover it, leave it for about a day, adding more water if it seems in danger of drying out, until it recrystallizes with a high water content keeping it malleable to the touch; congratulations, you now have a very simple scrub. This should still not be used more than, say, once per week, though.
Last but not least, you might consider investing in a konjac sponge; they gently remove dead skin without damaging living skin. Here’s an example product on Amazon, for your convenience

When can my baby drink cow’s milk? It’s sooner than you think
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.
Parents are often faced with well-meaning opinions and conflicting advice about what to feed their babies.
The latest guidance from the World Health Organization (WHO) recommends formula-fed babies can switch to cow’s milk from six months. Australian advice says parents should wait until 12 months. No wonder some parents, and the health professionals who advise them, are confused.
So what do parents need to know about the latest advice? And when is cow’s milk an option?
What’s the updated advice?
Last year, the WHO updated its global feeding guideline for children under two years old. This included recommending babies who are partially or totally formula fed can have whole animal milks (for example, full-fat cow’s milk) from six months.
This recommendation was made after a systematic review of research by WHO comparing the growth, health and development of babies fed infant formula from six months of age with those fed pasteurised or boiled animal milks.
The review found no evidence the growth and development of babies who were fed infant formula was any better than that of babies fed whole, fresh animal milks.
The review did find an increase in iron deficiency anaemia in babies fed fresh animal milk. However, WHO noted this could be prevented by giving babies iron-rich solid foods daily from six months.
On the strength of the available evidence, the WHO recommended babies fed infant formula, alone or in addition to breastmilk, can be fed animal milk or infant formula from six months of age.
The WHO said that animal milks fed to infants could include pasteurised full-fat fresh milk, reconstituted evaporated milk, fermented milk or yoghurt. But this should not include flavoured or sweetened milk, condensed milk or skim milk.
If you’re choosing cow’s milk for your baby, make sure it’s whole milk rather than skim milk. Mr Adi/Shutterstock Why is this controversial?
Australian government guidelines recommend “cow’s milk should not be given as the main drink to infants under 12 months”. This seems to conflict with the updated WHO advice. However, WHO’s advice is targeted at governments and health authorities rather than directly at parents.
The Australian dietary guidelines are under review and the latest WHO advice is expected to inform that process.
OK, so how about iron?
Iron is an essential nutrient for everyone but it is particularly important for babies as it is vital for growth and brain development. Babies’ bodies usually store enough iron during the final few weeks of pregnancy to last until they are at least six months of age. However, if babies are born early (prematurely), if their umbilical cords are clamped too quickly or their mothers are anaemic during pregnancy, their iron stores may be reduced.
Cow’s milk is not a good source of iron. Most infant formula is made from cow’s milk and so has iron added. Breastmilk is also low in iron but much more of the iron in breastmilk is taken up by babies’ bodies than iron in cow’s milk.
Babies should not rely on milk (including infant formula) to supply iron after six months. So the latest WHO advice emphasises the importance of giving babies iron-rich solid foods from this age. These foods include:
- meat
- eggs
- vegetables, including beans and green leafy vegetables
- pulses, including lentils
- ground seeds and nuts (such as peanut or other nut butters, but with no added salt or sugar).
You may have heard that giving babies whole cow’s milk can cause allergies. In fact, whole cow’s milk is no more likely to cause allergies than infant formula based on cow’s milk.
If you’re introducing cow’s milk at six months, offer iron-rich foods too, such as meat or lentils. pamuk/Shutterstock What are my options?
The latest WHO recommendation that formula-fed babies can switch to cow’s milk from six months could save you money. Infant formula can cost more than five times more than fresh milk (A$2.25-$8.30 a litre versus $1.50 a litre).
For families who continue to use infant formula, it may be reassuring to know that if infant formula becomes hard to get due to a natural disaster or some other supply chain disruption fresh cow’s milk is fine to use from six months.
It is also important to know what has not changed in the latest feeding advice. WHO still recommends infants have only breastmilk for their first six months and then continue breastfeeding for up to two years or more. It is also still the case that infants under six months who are not breastfed or who need extra milk should be fed infant formula. Toddler formula for children over 12 months is not recommended.
All infant formula available in Australia must meet the same standard for nutritional composition and food safety. So, the cheapest infant formula is just as good as the most expensive.
What’s the take-home message?
The bottom line is your baby can safely switch from infant formula to fresh, full-fat cow’s milk from six months as part of a healthy diet with iron-rich foods. Likewise, cow’s milk can also be used to supplement or replace breastfeeding from six months, again alongside iron-rich foods.
If you have questions about introducing solids your GP, child health nurse or dietitian can help. If you need support with breastfeeding or starting solids you can call the National Breastfeeding Helpline (1800 686 268) or a lactation consultant.

Minimize Aging’s Metabolic Slump

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!
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 know that metabolism slows with age, are there any waypoints or things to look out for? I don’t know whether I should be eating less, or doing less, or taking some other approach entirely. What’s recommended?❞
Age and sex count for a lot with this one! As metabolism is in large part directed by hormones:
- For men, declining testosterone (often from around 45 onwards) can result in a metabolic slump
- For women, declining estrogen with the menopause does have an effect, but progesterone is the bigger factor for metabolism in the sense you are talking about.
In both cases, simply taking more of those hormones can often help, but please of course speak with an endocrinologist if that seems like a possible option for you, as your circumstances (and physiology) may vary.
If you’d like to go to that conversation well-armed with information, here are some good starting points, by the way:
- The Testosterone Drop, & Topping Up Testosterone
- Menopausal HRT: Bioidentical vs Animal (It Makes A Difference!)
And if you’re wondering about the natural vs pharmaceutical approaches…

- What You Should Have Been Told About The Menopause Beforehand
About your metabolic base rate
We tend to think of “fast metabolism good, slow metabolism bad”, and that’s a reasonable general premise… but it’s not necessarily always so.
After all, if you could double your metabolism and keep it there all the time, without changing anything else, well… You’ve heard the phrase “burning the candle at both ends”? So, having at least some downtime is important too.
See for example: Sleep Deprivation & Diabetes Risk
What’s critical, when it comes to base metabolic rate, is that your body must be capable of adequately processing what you are putting into it. Because if your body can’t keep up with the input, it’ll just start storing the excess chemical energy in the quickest and easiest way possible.
…which is a fast track to metabolic disorder in general and type 2 diabetes in particular. For more on the science and mechanics of this, see:
How To Prevent And Reverse Type 2 Diabetes
As for portion sizes…
Your body knows what you need, so listen to it. There is no external source of knowledge that can tell you how much food you need better than your own body itself can tell you.
You may be wondering “how exactly do I listen to my body, though?”, in which case, check out:
The Kitchen Doctor: Interoception & Mindful Eating
As for exercise…
When you exercise, your metabolic rate temporarily increases. After most kinds of exercise, your metabolism slumps again afterwards to compensate.
There are two ways to avoid this:
- Exercise Less, Move More ← it’s about maximizing time spent not sitting still
- High Intensity Interval Training ← a special kind of exercise, the only one known to keep the metabolism running high for a couple of hours afterwards, with no counter-slump
…which makes it pretty effective indeed

Wheat Belly, Revised & Expanded Edition – by Dr. William Davis
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 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!

7 Kinds Of Rest When Sleep Is Not Enough
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.
Taking Rest Seriously (More Than Just Sleep)
This is Dr. Matthew Edlund. He has 44 years experience as a psychiatrist, and is also a sleep specialist. He has a holistic view of health, which is reflected in his practice; he advocates for “a more complete health: physical, mental, social, and spiritual well-being”.
What does he want us to know?
Sleep, yes
Sleep cannot do all things for us in terms of rest, but it can do a lot, and it is critical. It is, in short, a necessary-but-not-sufficient condition for being well-rested.
See also: Why You Probably Need More Sleep
Rest actively
Rest is generally thought of as a passive activity, if you’ll pardon the oxymoron. Popular thinking is that it’s not something defined by what we do, so much what we stop doing.
In contrast, Dr. Edlund argues that to take rest seriously, we need do restful things.
Rest is as important as eating, and we wouldn’t want for that to “just happen”, would we?
Dr. Edlund advocates for restful activities such as going to the garden (or a nearby park) to relax. He also suggests we not underestimate the power of sex as an actively restful activity—this one is generally safer in the privacy of one’s home, though!
Rest physically
This is about actively relaxing our body—yoga is a great option here, practised in a way that is not physically taxing, but is physically rejuvenating; gentle stretches are key. Without such things, our body will keep tension, and that is not restful.
For the absolute most restful yogic practice? Check out:
Non-Sleep Deep Rest: A Neurobiologist’s Take
this is about yoga nidra!
Rest mentally
The flipside of the above is that we do need to rest our mind also. When we try to rest from a mental activity by taking on a different mental activity that uses the same faculties of the brain, it is not restful.
Writer’s example: as a writer, I could not rest from my writing by writing recreationally, or even by reading. An accountant, however, could absolutely rest from accounting by picking up a good book, should they feel so inclined.
Rest socially
While we all have our preferences when it comes to how much or how little social interaction we like in our lives, humans are fundamentally social creatures, and it is hardwired into us by evolution to function at our best in a community.
This doesn’t mean you have to go out partying every night, but it does mean you should take care to spend at least a little time with friends, even if just once or twice per week, and yes, even if it’s just a videocall (in person is best, but not everyone lives close by!)
If your social life is feeling a little thin on the ground these days, that’s a very common thing—not only as we get older, but also as many social institutions took a dive in functionality on account of the pandemic, and many are still floundering. Nevertheless, there are more options than you probably realize; yes, even for the naturally reclusive:
How To Beat Loneliness & Isolation
Rest spiritually
Be we religious or not, there are scientifically well-evidenced benefits to religious practices—some are because of the social aspect, and follow on from what we talked about just above. Other benefits come from activities such as prayer or meditation (which means that having some kind of faith, while beneficial, is not actually a requirement for spiritual rest—comparable practices without faith are fine too).
We discussed the overlapping practices of prayer and meditation, here:
The Science Of Mantra Meditation
Rest at home
Obviously, most people sleep at home. But…
Busy family homes can sometimes need a bit of conscious effort to create a restful environment, even if just for a while. A family dinner together is one great way to achieve this, and also ties in with the social element we mentioned before!
A different challenge faced by a lot of older people without live-in families, on the other hand, is the feeling of too much opportunity for rest—and then a feeling of shame for taking it. The view is commonly held that, for example, taking an afternoon nap is a sign of weakness.
On the contrary: taking an afternoon nap can be a good source of strength! Check out:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
Rest at work
Our readership has a lot of retirees, but we know that’s not the case for everyone. How then, to rest while at work? Ideally we have breaks, of course, but most workplaces do not exactly have an amusement arcade in the break room. Nevertheless, there are some quick resets that can be done easily, anywhere, and (almost) any time:

Feel-Good Productivity – by Dr. Ali Abdaal
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.
“Rise and grind” is not a sustainable way to live. Yet for most of us, there are things we do have to do every day that we don’t necessarily do for fun. So, how to be productive with those things, and not feel like we are constantly compromising and sacrificing our time on this earth for some intrinsically trivial but extrinsically required activity that’ll be forgotten tomorrow?
And most of us do also have dreams and ambitions (and if you don’t, then what were they before life snatched them away from you?), things to work towards. So there is “carrot” for us as well as “stick”. But how to break the cycle and get more carrot and less stick, while being more productive than before?
Dr. Abdaal frames this principally in terms of neurology first, psychology next.
That when we are bored, we simply do not have the neurochemicals required to work well anyway, so addressing that first needs to be a priority. He lays out many ways of doing this, gives lots of practical tips, and brings attention to the ways it’s easy to go wrong (and how to fix those too).
The writing style isdeceptively relaxed and casual, leading the reader smoothly into understanding of each topic before moving on.
Bottom line: if you want to get more done while feeling better about it (not a tired wreck), then this is the book for you!

Indistractable – by Nir Eyal
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.
Have you ever felt that you could accomplish anything you wanted/needed, if only you didn’t get distracted?
This book lays out a series of psychological interventions for precisely that aim, and it goes a lot beyond the usual “download/delete these apps to help you stop checking social media every 47 seconds”.
Some you’ll have heard of before, some you won’t have, and if even one method works for you, it’ll have been well worth your while reading this book. This reviewer, for example, enjoyed the call to identity-based strength, e.g. adopting an “I am indistractable*” perspective going into tasks. This is akin to the strength of, for example, “I don’t drink” over “I am a recovering alcoholic”.
*the usual spelling of this, by the way, is “undistractable”, but we use the author’s version here for consistency. It’s a great marketing gimmick, as all searches for the word “indistractable” will bring up his book.
Nor is the book just about maximizing productivity to the detriment of everything else; this is not about having a 25 hours per day “grindset”. Rather, it even makes sure to cover such things as focusing on one’s loved ones, for instance.
Bottom line: if you’ve tried blocking out the distractions but still find you can’t focus, this book offers next-level solutions
