Health Coach Kait (BSc Nutrition & Exercise) is a certified health and nutrition coach, and today she’s here to talk about iodine—which is important for many of our body functions, from thyroid hormone production to metabolic regulation to heart rate management, as well as more superficial-but-important-too things like our skin and hair.
Kait’s hitlist
Here’s what she recommends we look out for:
- Swollen neck: even a slightly swollen neck might indicate low iodine levels (this is because that’s where the thyroid glands are)
- Hair loss: iodine is needed for healthy hair growth, so a deficiency can lead to hair loss / thinning hair
- Dry and flaky skin: with iodine’s role in our homeostatic system not being covered, our skin can dry out as a result
- Feeling cold all the time: because of iodine’s temperature-regulating activities
- Slow heart rate: A metabolic slump due to iodine deficiency can slow down the heart rate, leading to fatigue and weakness (and worse, if it persists)
- Brain fog: trouble focusing can be a symptom of the same metabolic slump
- Fatigue: this is again more or less the same thing, but she said eight signs, so we’re giving you the eight!
- Irregular period (if you normally have such, of course): because iodine affects reproductive hormones too, an imbalance can disrupt menstrual cycles.

Life Is in the Transitions – by Bruce Feiler

Change happens. Sometimes, because we choose it. More often, we don’t get a choice.
Our bodies change; with time, with illness, with accident or incident, or even, sometimes, with effort. People in our lives change; they come, they go, they get sick, they die. Our working lives change; we get a job, we lose a job, we change jobs, our jobs change, we retire.
Whether we’re undergoing cancer treatment or a religious conversion, whether our families are growing or down to the last few standing, change is inescapable.
Our author makes the case that on average, we each undergo at least 5 major “lifequakes”; changes that shake our lives to the core. Sometimes one will come along when we’ve barely got back on our feet from the previous—if we have at all.
What, then, to do about this? We can’t stop change from occurring, and some changes aren’t easy to “roll with”. Feiler isn’t prescriptive about this, but rather, descriptive:
By looking at the stories of hundreds of people he interviewed for this book, he looks at how people pivoted on the spot (or picked up the pieces!) and made the best of their situation—or didn’t.
Bottom line: zooming out like this, looking at many people’s lives, can remind us that while we don’t get to choose what winds we get swept by, we at least get to choose how we set the sails. The examples of others, as this book gives, can help us make better decisions.

No, taking drugs like Ozempic isn’t ‘cheating’ at weight loss or the ‘easy way out’
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.
Hundreds of thousands of people worldwide are taking drugs like Ozempic to lose weight. But what do we actually know about them? This month, The Conversation’s experts explore their rise, impact and potential consequences.
Obesity medication that is effective has been a long time coming. Enter semaglutide (sold as Ozempic and Wegovy), which is helping people improve weight-related health, including lowering the risk of a having a heart attack or stroke, while also silencing “food noise”.
As demand for semaglutide increases, so are claims that taking it is “cheating” at weight loss or the “easy way out”.
We don’t tell people who need statin medication to treat high cholesterol or drugs to manage high blood pressure they’re cheating or taking the easy way out.
Nor should we shame people taking semaglutide. It’s a drug used to treat diabetes and obesity which needs to be taken long term and comes with risks and side effects, as well as benefits. When prescribed for obesity, it’s given alongside advice about diet and exercise.
How does it work?
Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1RA). This means it makes your body’s own glucagon-like peptide-1 hormone, called GLP-1 for short, work better.
GLP-1 gets secreted by cells in your gut when it detects increased nutrient levels after eating. This stimulates insulin production, which lowers blood sugars.
GLP-1 also slows gastric emptying, which makes you feel full, and reduces hunger and feelings of reward after eating.
GLP-1 receptor agonist (GLP-1RA) medications like Ozempic help the body’s own GLP-1 work better by mimicking and extending its action.
Some studies have found less GLP-1 gets released after meals in adults with obesity or type 2 diabetes mellitus compared to adults with normal glucose tolerance. So having less GLP-1 circulating in your blood means you don’t feel as full after eating and get hungry again sooner compared to people who produce more.
GLP-1 has a very short half-life of about two minutes. So GLP-1RA medications were designed to have a very long half-life of about seven days. That’s why semaglutide is given as a weekly injection.
What can users expect? What does the research say?
Higher doses of semaglutide are prescribed to treat obesity compared to type 2 diabetes management (up to 2.4mg versus 2.0mg weekly).
A large group of randomised controlled trials, called STEP trials, all tested weekly 2.4mg semaglutide injections versus different interventions or placebo drugs.
Trials lasting 1.3–2 years consistently found weekly 2.4 mg semaglutide injections led to 6–12% greater weight loss compared to placebo or alternative interventions. The average weight change depended on how long medication treatment lasted and length of follow-up.
Weight reduction due to semaglutide also leads to a reduction in systolic and diastolic blood pressure of about 4.8 mmHg and 2.5 mmHg respectively, a reduction in triglyceride levels (a type of blood fat) and improved physical function.
Another recent trial in adults with pre-existing heart disease and obesity, but without type 2 diabetes, found adults receiving weekly 2.4mg semaglutide injections had a 20% lower risk of specific cardiovascular events, including having a non-fatal heart attack, a stroke or dying from cardiovascular disease, after three years follow-up.
Who is eligible for semaglutide?
Australia’s regulator, the Therapeutic Goods Administration (TGA), has approved semaglutide, sold as Ozempic, for treating type 2 diabetes.
However, due to shortages, the TGA had advised doctors not to start new Ozempic prescriptions for “off-label use” such as obesity treatment and the Pharmaceutical Benefits Scheme doesn’t currently subsidise off-label use.
The TGA has approved Wegovy to treat obesity but it’s not currently available in Australia.
When it’s available, doctors will be able to prescribe semaglutide to treat obesity in conjunction with lifestyle interventions (including diet, physical activity and psychological support) in adults with obesity (a BMI of 30 or above) or those with a BMI of 27 or above who also have weight-related medical complications.
What else do you need to do during Ozempic treatment?
Checking details of the STEP trial intervention components, it’s clear participants invested a lot of time and effort. In addition to taking medication, people had brief lifestyle counselling sessions with dietitians or other health professionals every four weeks as a minimum in most trials.
Support sessions were designed to help people stick with consuming 2,000 kilojoules (500 calories) less daily compared to their energy needs, and performing 150 minutes of moderate-to-vigorous physical activity, like brisk walking, dancing and gardening each week.
STEP trials varied in other components, with follow-up time periods varying from 68 to 104 weeks. The aim of these trials was to show the effect of adding the medication on top of other lifestyle counselling.
A review of obesity medication trials found people reported they needed less cognitive behaviour training to help them stick with the reduced energy intake. This is one aspect where drug treatment may make adherence a little easier. Not feeling as hungry and having environmental food cues “switched off” may mean less support is required for goal-setting, self-monitoring food intake and avoiding things that trigger eating.
But what are the side effects?
Semaglutide’s side-effects include nausea, diarrhoea, vomiting, constipation, indigestion and abdominal pain.
In one study these led to discontinuation of medication in 6% of people, but interestingly also in 3% of people taking placebos.
More severe side-effects included gallbladder disease, acute pancreatitis, hypoglycaemia, acute kidney disease and injection site reactions.
To reduce risk or severity of side-effects, medication doses are increased very slowly over months. Once the full dose and response are achieved, research indicates you need to take it long term.
Given this long-term commitment, and associated high out-of-pocket cost of medication, when it comes to taking semaglutide to treat obesity, there is no way it can be considered “cheating”.

The Body Is Not an Apology – by Sonya Renee Taylor

First, a couple of things that this book is not about:
- Self-confidence (it’s about more than merely thinking highly of oneself)
- Self-acceptance (it’s about more than merely settling for “good enough”)
In contrast, it’s about loving and celebrating what is, while striving for better, for oneself and for others.
You may be wondering: whence this “radical” in the title?
The author argues that often, the problem with our bodies is not actually our bodies. If we have cancer, or diabetes, then sure, that’s a problem with the body. But most of the time, the “problem with our bodies” is simply society’s rejection of our “imperfect” bodies as somehow “less than”, and something we must invest time and money to correct. Hence, the need for a radical uprooting of ideas, to fix the real problem.
Bottom line: if, like most of us, you have a body that would not entirely pass for that of a Marvel Comics superhero, this is a book for you. And if you do have a MCU body? This is also a book for you, because we have bad news for you about what happens with age.

Cupping: How It Works (And How It Doesn’t)
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.
Good Health By The Cup?
In Tuesday’s newsletter, we asked you for your opinion of cupping (the medical practice), and got the above-depicted, below-described, set of responses:
- About 40% said “It may help by improving circulation and stimulating the immune system”
- About 26% said “I have never heard of the medical practice of cupping before this”
- About 19% said “It is pseudoscience and/or placebo at best, but probably not harmful
- About 9% said “It is a good, evidence-based practice that removes toxins and stimulates health”
- About 6% said “It is a dangerous practice that often causes harm to people who need medical help”
So what does the science say?
First, a quick note for those unfamiliar with cupping: it is the practice of placing a warmed cup on the skin (open side of the cup against the skin). As the warm air inside cools, it reduces the interior air pressure, which means the cup is now (quite literally) a suction cup. This pulls the skin up into the cup a little. The end result is visually, and physiologically, the same process as what happens if someone places the nozzle of a vacuum cleaner against their skin. For that matter, there are alternative versions that simply use a pump-based suction system, instead of heated cups—but the heated cups are most traditional and seem to be most popular. See also:
National Center for Complementary and Integrative Health | Cupping
It is a dangerous practice that often causes harm to people who need medical help: True or False?
False, for any practical purposes.
- Directly, it can (and usually does) cause minor superficial harm, much like many medical treatments, wherein the benefits are considered to outweigh the harm, justifying the treatment. In the case of cupping, the minor harm is usually a little bruising, but there are other risks; see the link we gave just above.
- Indirectly, it could cause harm by emboldening a person to neglect a more impactful treatment for their ailment.
But, there’s nothing for cupping akin to the “the most common cause of death is when someone gets a vertebral artery fatally severed” of chiropractic, for example.
It is a good, evidence-based practice that removes toxins and stimulates health: True or False?
True and False in different parts. This one’s on us; we included four claims in one short line. But let’s look at them individually:
- Is it good? Well, those who like it, like it. It legitimately has some mild health benefits, and its potential for harm is quite small. We’d call this a modest good, but good nonetheless.
- Is it evidence-based? Somewhat, albeit weakly; there are some papers supporting its modest health claims, although the research is mostly only published in journals of alternative medicine, and any we found were in journals that have been described by scientists as pseudoscientific.
- Does it remove toxins? Not directly, at least. There is also a version that involves making a small hole in the skin before applying the cup, the better to draw out the toxins (called “wet cupping”). This might seem a little medieval, but this is because it is from early medieval times (wet cupping’s first recorded use being in the early 7th century). However, the body’s response to being poked, pierced, sucked, etc is to produce antibodies, and they will do their best to remove toxins. So, indirectly, there’s an argument.
- Does it stimulate health? Yes! We’ll come to that shortly. But first…
It is pseudoscience and/or placebo at best, but probably not harmful: True or False?
True in that its traditionally-proposed mechanism of action is a pseudoscience and placebo almost certainly plays a strong part, and also in that it’s generally not harmful.
On it being a pseudoscience: we’ve talked about this before, but it bears repeating; just because something’s proposed mechanism of action is pseudoscience, doesn’t necessarily mean it doesn’t work by some other mechanism of action. If you tell a small child that “eating the rainbow” will improve their health, and they believe this is some sort of magical rainbow power imbuing them with health, then the mechanism of action that they believe in is a pseudoscience, but eating a variety of colorful fruit and vegetables will still be healthy.
In the case of cupping, its proposed mechanism of action has to do withbalancing qi, yin and yang, etc (for which scientific evidence does not exist), in combination with acupuncture lore (for which some limited weak scientific evidence exists). On balancing qi, yin and yang etc, this is a lot like Europe’s historically popular humorism, which was based on the idea of balancing the four humors (blood, yellow bile, black bile, phlegm). Needless to say, humorism was not only a pseudoscience, but also eventually actively disproved with the advent of germ theory and modern medicine. Cupping therapy is not more scientifically based than humorism.
On the placebo side of things, there probably is a little more to it than that; much like with acupuncture, a lot of it may be a combination of placebo and using counter-irritation, a nerve-tricking method to use pain to reduce pain (much like pressing with one’s nail next to an insect bite).
Here’s one of the few studies we found that’s in what looks, at a glance, to be a reputable journal:
Cupping therapy and chronic back pain: systematic review and meta-analysis
It may help by improving circulation and stimulating the immune system: True or False?
True! It will improve local circulation by forcing blood into the area, and stimulate the immune system by giving it a perceived threat to fight.
Again, this can be achieved by many other means; acupuncture (or just “dry needling”, which is similar but without the traditional lore), a cold shower, and/or exercise (and for that matter, sex—which combines exercise, physiological arousal, and usually also foreign bodies to respond to) are all options that can improve circulation and stimulate the immune system.

Dr. Suzanne Steinbaum’s Heart Book – by Dr. Suzanne Steinbaum
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 book is divided into three parts:
- What you should know
- What you should do
- All about you
This is a very useful format, since it lays out all the foundational knowledge, before offering practical advice and “how to” explanations, before finally wrapping up with personalizing things.
The latter is important, because while our basic risk factors can be assembled in a few lines of data (age, sex, race, genes, diet, exercise habits, etc) there’s a lot more to us than that, and oftentimes the data that doesn’t make the cut, makes the difference. Hormones on high on this list; we can say that a person is a 65-year-old woman and make a guess, but that’s all it is: a guess. Very few of us are the “average person” that statistical models represent accurately. And nor are social and psychological factors irrelevant; in fact often they are deciding factors!
So, it’s important to be able to look at ourselves as the whole persons we are, or else we’ll get a heart-healthy protocol that works on paper but actually falls flat in application, because the mathematical model didn’t take into account that lately we have been very stressed about such-and-such a thing, and deeply anxious about so-and-so, and a hopefully short-term respiratory infection has reduced blood oxygen levels, and all these kinds of things need to be taken into account too, for an overall plan to work.
The greatest strength of this book is that it attends to that.
The style of the book is a little like a long sales pitch (when all that’s being sold, by the way, is the ideas the book is offering; she wants you to take her advice with enthusiasm), but there’s plenty of very good information all the way through, making it quite worth the read.
Bottom line: if you’re a woman and/or love at least one woman, then you can benefit from this important book for understanding heart health that’s not the default.

This Root Might Be A Guardian Angel
Sometimes we go searching for supplements to research; sometimes supplements present themselves for examination! In this case, our attention was grabbed by a headline:
Angelica gigas extract emerges as a potential treatment for vascular disease
Angelica who?
Angelica gigas, also called the purple parsnip (amongst other names), is a flowering plant native to Korea. It has assorted medicinal properties, and in this case, it was its heart-healthy benefits that were making news:
❝Ultimately, this study presents clearly evidence that Angelica gigas extract is a promising natural product-based functional food/herbal medicine candidate for preventing or regulating hyperlipidemic cardiovascular complications❞
But it has a lot more to offer…
The root has various bioactive metabolites, but the compounds that most studies are most interested in are decursin and decursinol, for their neuroprotective and cognitive enhancement effects:
❝[C]rude extracts and isolated components from the root of A. gigas exhibited neuroprotective and cognitive enhancement effects.
Neuronal damage or death is the most important factor for many neurodegenerative diseases.
In addition, recent studies have clearly demonstrated the possible mechanisms behind the neuroprotective action of extracts/compounds from the root of A. gigas.❞
That middle paragraph there? That’s one of the main pathogenic processes of Alzheimer’s, Parkinson’s, Huntington’s, and Multiple Sclerosis.
Angelica gigas attenuates (reduces the force of) that process:
❝The published reports revealed that the extracts and isolated components from the root of A. gigas showed neuroprotective and cognitive enhancement properties through various mechanisms such as anti-apoptosis, antioxidative actions, inhibiting mRNA and protein expressions of inflammatory mediators and regulating a number of signaling pathways.
In conclusion, the A. gigas root can serve as an effective neuroprotective agent by modulating various pathophysiological processes❞
Read more: Neuroprotective and Cognitive Enhancement Potentials of Angelica gigas Nakai Root: A Review
Beyond neuroprotection & cognitive enhancement
…and also beyond its protection against vascular disease, which is what got our attention…
Angelica gigas also has antioxidant properties, anti-cancer properties, and general immune-boosting properties.
We’ve only so much room, so: those links above will take you to example studies for those things, but there are plenty more where they came from, so we’re quite confident in this one.
Of course, what has antioxidant properties is usually anti-inflammatory, anti-cancer, and anti-aging, because these things are reliant on many of the same processes as each other, with a lot of overlap.
Where can we get it?
We don’t sell it, but here’s an example product on Amazon, for your convenience
