PFAS & Cancer Risk: The Numbers Are High
This is Dr. Maaike van Gerwen. Is that an MD or a PhD, you wonder? It’s both.
She’s also Director of Research in the Department of Otolaryngology at Mount Sinai Hospital in New York, Scientific Director of the Program of Personalized Management of Thyroid Disease, and Member of the Institute for Translational Epidemiology and the Transdisciplinary Center on Early Environmental Exposures.
What does she want us to know?
She’d love for us to know about her latest research published literally today, about the risks associated with PFAS, such as the kind widely found in non-stick cookware:
Per- and polyfluoroalkyl substances (PFAS) exposure and thyroid cancer risk
Dr. van Gerwen and her team tested this several ways, and the very short and simple version of the findings is that per doubling of exposure, there was a 56% increased rate of thyroid cancer diagnosis.
(The rate of exposure was not just guessed based on self-reports; it was measured directly from PFAS levels in the blood of participants)
- PFAS exposure can come from many sources, not just non-stick cookware, but that’s a “biggie” since it transfers directly into food that we consume.
- Same goes for widely-available microwaveable plastic food containers.
- Relatively less dangerous exposures include waterproofed clothing.
To keep it simple and look at the non-stick pans and microwavable plastic containers, doubling exposure might mean using such things every day vs every second day.
Practical take-away: PFAS may be impossible to avoid completely, but even just cutting down on the use of such products is already reducing your cancer risk.
Isn’t it too late, by this point in life? Aren’t they “forever chemicals”?
They’re not truly “forever”, but they do have long half-lives, yes.
See: Can we take the “forever” out of forever chemicals?
The half-lives of PFOS and PFOA in water are 41 years and 92 years, respectively.
In the body, however, because our body is constantly trying to repair itself and eliminate toxins, it’s more like 3–7 years.
That might seem like a long time, and perhaps it is, but the time will pass anyway, so might as well get started now, rather than in 3–7 years time!

What should we use instead?
In place of non-stick cookware, cast iron is fantastic. It’s not everyone’s preference, though, so you might also like to know that ceramic cookware is a fine option that’s functionally non-stick but without needing a non-stick coating. Check for PFAS-free status; they should advertise this.
In place of plastic microwaveable containers, Pyrex (or equivalent) glass dishes (you can get them with lids) are a top-tier option. Ceramic containers (without metallic bits!) are also safely microwaveable.

Muir Glen Organic vs First Field Original – 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 Muir Glen Organic Ketchup to First Field Original Ketchup, we picked the First Field.
Why?
This one was a little unfair to you, as you can’t turn them around to read the ingredients here. But the point we want to share the most today is: you have to turn them around and read the ingredients! You absolutely cannot rely on appearances!
While the Muir Glen Organic may have a very “greenwashed” aesthetic going on and the word “organic” is more eye-catching than any other word on the label, it contains 4x as much sugar and 4x as much sodium.
Side-by-side, they have, per tablespoon:
First Field Original: 1g sugar, 60mg sodium
Muir Glen Organic: 4g sugar, 240mg sodiumBut what about the importance of being organic?
Well, we have one more surprise for you: the First Field ketchup is organic too, non-GMO, and contains no added concentrates either.
This isn’t an ad for First Field (by all means enjoy their products or don’t; we’re not invested), but it is a heartfelt plea to always check the backs of products and read the labels, because fronts of products can’t be relied upon at all.
I’m sure we all get caught out sometimes, but the less often, the better!
PS: we write this, of course, before seeing the results of your voting. Maybe it won’t be a “Muir Glen Organic” sweep in the polls. But either way, it’s a call to vigilance, and a “very good, carry on” to everyone who does this already

The Complete Anti-Inflammatory Diet for Beginners – by Dorothy Calimeris and Lulu Cook
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, about the authors: notwithstanding the names, Calimeris is the cook, and Cook is the nutritionist (and an RDN at that).
As for the book: we get a good primer on the science of inflammation, what it is, why it happens, what things are known to cause/trigger it, and what things are known to fight it. They do also go outside of nutrition a bit for this, speaking briefly on other lifestyle factors too, but the main focus is of course nutrition.
As for the recipes: while distinctly plants-forward (as one might expect of an anti-inflammatory eating book), it’s not outright vegan or even vegetarian, indeed, in the category of main dishes, there are sections for:
- Vegetarian and vegan
- Fish and shellfish
- Poultry and meat
…as well as, before and after those, sections for breakfast and brunch and snacks and sweets. As well as a not-to-be-underestimated section, for sauces, condiments, and dressings. This is important, because those are quite often the most inflammatory parts of an otherwise healthy meal! So being able to make anti-inflammatory versions is a real boon.
The recipes are mostly not illustrated, but the steps are very clearly described and easy to follow.
Bottom line: if inflammation is currently on your to-tackle list, this book will be an excellent companion in the kitchen.

Gut-Positive Pot Noodles
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.
Everything we consume either improves our health a little or worsens it. Pot noodles aren’t generally the healthiest foods, but these ones sure are! There’s quite a range of fiber in this, including the soluble fiber of the noodles themselves (which are, in fact, mostly fiber and water). As a bonus, the glucomannan in the noodles promotes feelings of fullness, notwithstanding its negligible carb count. Of course, the protein in the edamame beans also counts for satiety!
You will need
- ½ cup konjac noodles (also called shirataki), tossed in 1 tsp avocado oil (or sesame oil, if you don’t have avocado)
- 2 oz mangetout, thinly sliced
- 1 oz edamame beans
- ¼ carrot, grated
- 2 baby sweetcorn, cut in half lengthways
- 1 scallion, finely diced
- 1 heaped tsp crunchy peanut butter (omit if allergic)
- 1 tsp miso paste
- 1 tsp chili oil
- 1 tsp black pepper, coarse ground
- 1 tsp peeled-and-grated ginger
Method
(we suggest you read everything at least once before doing anything)
1) Layer a heat-resistant jar (mason jars are usually quite resistant to temperature changes) with the noodles and vegetables.
2) Combine the peanut butter, miso paste, and chili oil, black pepper, and ginger in a small bowl. Pour this dressing over the layered vegetables and noodles, and screw the lid on. Refrigerate until needed.
3) Add hot water to the jar and stir, to serve. If you prefer the vegetables to be more cooked, you can microwave (without the lid!) for a minute or two.
Enjoy!

Think Again – by Adam Grant
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.
Warning: this book may cause some feelings of self-doubt! Ride them out and see where they go, though.
It was Socrates who famously (allegedly) said “ἓν οἶδα ὅτι οὐδὲν οἶδα”—”I know that I know nothing”.
Adam Grant wants us to take this philosophy and apply it usefully to modern life. How?
The main premise is that rethinking our plans, answers and decisions is a good thing… Not a weakness. In contrast, he says, a fixed mindset closes us to opportunities—and better alternatives.
He wants us to be sure that we don’t fall into the trap of the Dunning-Kruger Effect (overestimating our abilities because of being unaware of how little we know), but he also wants us to rethink whole strategies, too. For example:
Grant’s approach to interpersonal conflict is very remniscent of another book we might review sometime, “Aikido in Everyday Life“. The idea here is to not give in to our knee-jerk responses to simply retaliate in kind, but rather to sidestep, pivot, redirect. This is, admittedly, the kind of “rethinking” that one usually has to rethink in advance—it’s too late in the moment! Hence the value of a book.
Nor is the book unduly subjective. “Wishy-washiness” has a bad rep, but Grant gives us plenty in the way of data and examples of how we can, for example, avoid losses by not doubling down on a mistake.
What, then, of strongly-held core principles? Rethinking doesn’t mean we must change our mind—it simply means being open to the possibility in contexts where such makes sense.
Grant borrows, in effect, from:
❝Do the best you can until you know better. Then when you know better… do better!❞
So, not so much undercutting the principles we hold dear, and instead rather making sure they stand on firm foundations.
All in all, a thought-provokingly inspiring read!

Next-Level Headache Hacks
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 Muscle With A Lot Of Therapeutic Value
First, a quick anatomy primer, so that the rest makes sense. We’re going to be talking about your sternocleidomastoid (SCM) muscle today.
To find it, there are two easy ways:
- look in a mirror, turn your head to one side and it’ll stick out on the opposite side of your neck
- look at this diagram
(we’re going to talk about it in the singular, but you have one on each side)
This muscle is interesting for very many reasons, but what we’re going to focus on today is that massaging/stretching it (correctly!) can benefit several things that are right next to it and/or behind it, namely:
- The tenth cranial nerve
- The eleventh cranial nerve
- The carotid artery
Why do we care about these?
Well, we would die quickly without the first and last of those. However, more practically, massaging each has benefits:
The tenth cranial nerve
This one is also known by its superhero alter-ego name:
The Vagus Nerve (And How You Can Make Use Of It)
The eleventh cranial nerve
This one’s not nearly so critical to life, but it does facilitate most of the motor functions in that general part of the body—including some mechanics of speech production, and maintaining posture of the shoulders/neck/head (which in turn strongly affects presence/absence of certain kinds of headaches).
The carotid artery
We suspect you know what this one does already; it supplies the brain (and the rest of your head, for that matter) with oxygenated blood.
What is useful to know today, is that it can be massaged, via the SCM, in a way that brings about a gentler version of this “one weird trick” to cure a lot of kinds of headaches:
Curing Headaches At Home With Actual Science
How (And Why) To Massage Your SCM
…to relieve many kinds of headache, migraine, eye-ache, and tension or pain the jaw. It’s not a magical cure all so this comes with no promises, but it can and will help with a lot of things.
In few words: turn your ahead away from the side where it hurts (if both, just pick one and then repeat for the other side), and slightly downwards. When your SCM sticks out a bit on the other side, gently pinch and rub it, working from the bottom to the top.
If you prefer videos, here is a demonstration:
How (And Why) To Stretch Your SCM
The above already includes a little stretch, but you can stretch it in a way that specifically stimulates your vagus nerve (this is good for many things).
In few words: stand (or sit) up straight, and interlace your fingers together. Put your hands on the back of your neck, thumbs-downwards, and (keeping your face forward) look to one side with your eyes only, and hold that until you feel the urge to yawn (it’ll probably take between about 3 seconds and 30 seconds). Then repeat on the other side.
If you prefer videos, this one is a very slight variation of what we just described but works the same way:
Take care!

Unlock Your Menopause Type – by Dr. Heather Hirsch
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 featured Dr. Hirsch before, here, and mentioned this book which, at the time, we had not yet reviewed. So, here it is:
What sets this apart from a lot of menopause books is that there’s a lot less “eat these foods and your body will magically stop exhibiting symptoms of menopause” and a lot more clinical observations and then evidence-based recommendations.
Which is not to say don’t eat broccoli and almonds; by all means, they’re great foods and contain valuable nutrients that will help. But it is to say that if your doctor’s prescription is just broccoli and almonds, maybe have those as a snack while you’re looking for a second opinion.
Dr. Hirsch goes through various “menopause types”, but it’s not so much “astrology for gynecologists” and more “here are clusters of menopause symptoms set against timeline of presentation, and they can be categorized into six main ways that between them, cover pretty much all my patients, which have been many”.
So if you, dear reader, are menopausal (including peri- or post-), then the chances are very good that you will see yourself in one of those six sets.
She then goes about how to prioritize relief and safety, and personalize a treatment plan, and maintain the best menopausal care for you, going forward.
The style is easy-reading pop-science, punctuated by clinical science and 35 pages of references. She’s also, unlike a lot of authors in the genre, manifestly not invested in being a celebrity or making a personality cult out of her recommendations; she’s happy to stick to the science and put out good advice.
Bottom line: if you or someone you love is menopausal (including peri- or post-), this is a top-tier book.
Click here to check out Unlock Your Menopause Type, and get the best care for you!
