The BAT-pause!

When Cold Weather & The Menopause Battle It Out
You may know that (moderate, safe) exposure to the cold allows our body to convert our white and yellow fat into the much healthier brown fat—also called brown adipose tissue, or “BAT” to its friends.
If you didn’t already know that, then well, neither did scientists until about 15 years ago:
The Changed Metabolic World with Human Brown Adipose Tissue: Therapeutic Visions
You can read more about it here:
Cool Temperature Alters Human Fat and Metabolism
This is important, especially because the white fat that gets converted is the kind that makes up most visceral fat—the kind most associated with all-cause mortality:
Visceral Belly Fat & How To Lose It ← this is not the same as your subcutaneous fat, the kind that sits directly under your skin and keeps you warm; this is the fat that goes between your organs and of which we should only have a small amount!
The BAT-pause
It’s been known (since before the above discovery) that BAT production slows considerably as we get older. Not too shocking—after all, many metabolic functions slow as we get older, so why should fat regulation be any different?
But! Rodent studies found that this was tied less to age, but to ovarian function: rats who underwent ovariectomies suffered reduced BAT production, regardless of their age.
Naturally, it’s been difficult to recreate such studies in humans, because it’s difficult to find a large sample of young adults willing to have their ovaries whipped out (or even suppressed chemically) to see how badly their metabolism suffers as a result.
Nor can an observational study (for example, of people who incidentally have ovaries removed due to ovarian cancer) usefully be undertaken, because then the cancer itself and any additional cancer treatments would be confounding factors.
Perimenopausal study to the rescue!
A recent (published last month, at time of writing!) study looked at women around the age of menopause, but specifically in cohorts before and after, measuring BAT metabolism.
By dividing the participants into groups based on age and menopausal status, and dividing the post-menopausal group into “takes HRT” and “no HRT” groups, and dividing the pre-menopausal group into “normal ovarian function” and “ovarian production of estrogen suppressed to mimic slightly early menopause” groups (there’s a drug for that), and then having groups exposed to warm and cold temperatures, and measuring BAT metabolism in all cases, they were able to find…
It is about estrogen, not age!
You can read more about the study here:
“Good” fat metabolism changes tied to estrogen loss, not necessarily to aging, shows study
…and the study itself, here:
Brown adipose tissue metabolism in women is dependent on ovarian status
What does this mean for men?
This means nothing directly for (cis) men, sorry.
But to satisfy your likely curiosity: yes, testosterone does at least moderately suppress BAT metabolism—based on rodent studies, anyway, because again it’s difficult to find enough human volunteers willing to have their testicles removed for science (without there being other confounding variables in play, anyway):
Testosterone reduces metabolic brown fat activity in male mice
So, that’s bad per se, but there isn’t much to be done about it, since the rest of your (addressing our male readers here) metabolism runs on testosterone, as do many of your bodily functions, and you would suffer many unwanted effects without it.
However, as men do typically have notably less body fat in general than women (this is regulated by hormones), the effects of changes in BAT metabolism are rather less pronounced in men (per testosterone level changes) than in women (per estrogen level changes), because there’s less overall fat to convert.
In summary…
While menopausal HRT is not necessarily a silver bullet to all metabolic problems, its BAT-maintaining ability is certainly one more thing in its favor.

The Immunostimulant Superfood

Eat These Greens!
Chlorella vulgaris, henceforth “chlorella”, is a simple green algae that has a lot of health benefits.
Note: most of the studies here are for Chlorella vulgaris specifically. However, some are for other species of the Chlorella genus, of which Chlorella vulgaris is by far the most common, hence the name (vulgaris = common). The relevant phytochemical properties appear to be the same regardless.
Superfood
While people generally take it as a supplement rather than a food item in any kind of bulk, it is more than 50% protein and contains all 9 essential amino acids.
As you might expect of a green superfood, it’s also full of many antioxidants, most of them carotenoids, and these pack a punch, for example against cancer:
It also has a lot of vitamins and minerals, and even omega-3.
Which latter also means it helps improve lipids and is thus particularly…
Heart healthy
❝Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol❞
Its heart-healthy benefits don’t stop at lipids though, and include blood pressure management, as in this study that found…
❝GABA-rich Chlorella significantly decreased high-normal blood pressure and borderline hypertension, and is a beneficial dietary supplement for prevention of the development of hypertension. ❞
About that GABA, if you’re curious about that, check out:
GABA Against Stress, Anxiety, & More
May remove heavy metals
We’re going with “may” for this one as we could only find animal studies so far (probably because most humans don’t have megadoses of heavy metals in them, which makes testing harder).
Here’s an example animal study, though:
Enhanced elimination of tissue methyl mercury in [Chlorella]-fed mice
Immunostimulant
This one’s clearer, for example in this 8-week study (with humans) that found…
❝Serum concentrations of interferon-γ (p<0.05) and interleukin-1β (p<0.001) significantly increased and that of interleukin-12 (p<0.1) tended to increase in the Chlorella group.
The increments of these cytokines after the intervention were significantly bigger in the Chlorella group than those in the placebo group. In addition, NK cell activities (%) were significantly increased in Chlorella group, but not in Placebo group.
The increments of NK cell activities (%) were also significantly bigger in the Chlorella group than the placebo group.
Additionally, changed levels of NK cell activity were positively correlated with those of serum interleukin-1β (r=0.280, p=0.047) and interferon-γ (r=0.271, p<0.005).❞
tl;dr = it boosts numerous different kinds of immune cells
PS, if you click though to the study, you may be momentarily alarmed by the first paragraph of the abstract that says “However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans“
this is from the “Background” section of the abstract, so what they are saying is “before we did this study, nobody had done this yet”.
So, be assured that the results are worthwhile and compelling.
Is it safe?
Based on the studies, it has a good safety profile. However, as it boosts the immune system, you may want to check with your doctor if you have an autoimmune disorder, and/or you are on immunosuppressants.
And in general, of course always check with your doctor/pharmacist if unsure about any potential drug interactions.

The Brain As A Work-In-Progress
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.
And The Brain Goes Marching On!
In Tuesday’s newsletter, we asked you “when does the human brain stop developing?” and got the above-depicted, below-described, set of responses:
- About 64% of people said “Never”
- About 16% of people said “25 years”
- About 9% of people said “65 years”
- About 5% of people said “13 years”
- About 3% of people said “18 years”
- About 3% of people said “45 years”
Some thoughts, before we get into the science:
An alternative wording for the original question was “when does the human brain finish developing”; the meaning is the same but the feeling is slightly different:
- “When does the human brain stop developing?” focuses attention on the idea of cessation, and will skew responses to later ages
- When does the human brain finish developing?” focuses on attention on a kind of “is it done yet?” and will skew responses to earlier ages
Ultimately, since we had to chose one word or another, we picked the shortest one, but it would have been interesting if we could have done an A/B test, and asked half one way, and half the other way!
Why we picked those ages
We picked those ages as poll options for reasons people might be drawn to them:
- 13 years: in English-speaking cultures, an important milestone of entering adolescence (note that the concept of a “teenager” is not precisely universal as most languages do not have “-teen” numbers in the same way; the concept of “adolescent” may thus be tied to other milestones)
- 18 years: age of legal majority in N. America and many other places
- 25 years: age popularly believed to be when the brain is finished developing, due to a study that we’ll talk about shortly (we guess that’s why there’s a spike in our results for this, too!)
- 45 years: age where many midlife hormonal changes occur, and many professionals are considered to have peaked in competence and start looking towards retirement
- 65 years: age considered “senior” in much of N. America and many other places, as well as the cut-off and/or starting point for a lot of medical research
Notice, therefore, how a lot of things are coming from places they really shouldn’t. For example, because there are many studies saying “n% of people over 65 get Alzheimer’s” or “n% of people over 65 get age-related cognitive decline”, etc, 65 becomes the age where we start expecting this—because of an arbitrary human choice of where to draw the cut-off for the study enrollment!
Similarly, we may look at common ages of legal majority, or retirement pensions, and assume “well it must be for a good reason”, and dear reader, those reasons are more often economically motivated than they are biologically reasoned.
So, what does the science say?
Our brains are never finished developing: True or False?
True! If we define “finished developing” as “we cease doing neurogenesis and neuroplasticity is no longer in effect”.
Glossary:
- Neurogenesis: the process of creating new brain cells
- Neuroplasticity: the process of the brain adapting to changes by essentially rebuilding itself to suit our perceived current needs
We say “perceived” because sometimes neuroplasticity can do very unhelpful things to us (e.g: psychological trauma, or even just bad habits), but on a biological level, it is always doing its best to serve our overall success as an organism.
For a long time it was thought that we don’t do neurogenesis at all as adults, but this was found to be untrue:
How To Grow New Brain Cells (At Any Age)
Summary of conclusions of the above: we’re all growing new brain cells at every age, even if we be in our 80s and with Alzheimer’s disease, but there are things we can do to enhance our neurogenic potential along the way.
Neuroplasticity will always be somewhat enhanced by neurogenesis (after all, new neurons get given jobs to do), and we reviewed a great book about the marvels of neuroplasticity including in older age:
Our brains are still developing up to the age of 25: True or False?
True! And then it keeps on developing after that, too. Now this is abundantly obvious considering what we just talked about, but see what a difference the phrasing makes? Now it makes it sound like it stops at 25, which this statement doesn’t claim at all—it only speaks for the time up to that age.
A lot of the popular press about “the brain isn’t fully mature until the age of 25” stems from a 2006 study that found:
❝For instance, frontal gray matter volume peaks at about age 11.0 years in girls and 12.1 years in boys, whereas temporal gray matter volume peaks at about age at 16.7 years in girls and 16.2 years in boys. The dorsal lateral prefrontal cortex, important for controlling impulses, is among the latest brain regions to mature without reaching adult dimensions until the early 20s.❞
Source: Structural Magnetic Resonance Imaging of the Adolescent Brain
There are several things to note here:
- The above statement is talking about the physical size of the brain growing
- Nowhere does he say “and stops developing at 25”
However… The study only looked at brains up to the age of 25. After that, they stopped looking, because the study was about “the adolescent brain” so there has to be a cut-off somewhere, and that was the cut-off they chose.
This is the equivalent of saying “it didn’t stop raining until four o’clock” when the reality is that four o’clock is simply when you gave up on checking.
The study didn’t misrepresent this, by the way, but the popular press did!
Another 2012 study looked at various metrics of brain development, and found:
- Synapse overproduction into the teens
- Cortex pruning into the late 20s
- Prefrontal pruning into middle age at least (they stopped looking)
- Myelination beyond middle age (they stopped looking)
Source: Experience and the developing prefrontal cortex ← check out figure 1, and make sure you’re looking at the human data not the rat data
So how’s the most recent research looking?
Here’s a 2022 study that looked at 123,984 brain scans spanning the age range from mid-gestation to 100 postnatal years, and as you can see from its own figure 1… Most (if not all) brain-things keep growing for life, even though most slow down at some point, they don’t stop:
Brain charts for the human lifespan ← check out figure 1; don’t get too excited about the ventricular volume column as that is basically “brain that isn’t being a brain”. Do get excited about the rest, though!

The Cough Doctor
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 Cough Doctor
This is Dr. Peter Small, who worked in epidemiology since the beginning of HIV epidemic. He became a pioneer in the field of molecular epidemiology. As such, his work was a guiding beacon for the public health response to the resurgence of tuberculosis. He’s travelled the world spending years in various institutions studying all manner of respiratory illnesses…. These have ranged from tuberculosis to pneumonia to lung cancer and (back to epidemiology) Covid-19.
He’s now the Chief Medical Officer at…
Hyfe
Hyfe, a medical AI company, was founded in 2020. Its objective: to build acoustic tools for respiratory diagnostics and monitoring.
In other words: it records coughs and collects data about coughing.
❝It’s ironic how much people focus on counting steps while ignoring cough, which is far more consequential. Hyfe is a science-driven company with the technology to make cough count. Particularly now, with increased awareness of cough and the rapid growth of digital health driven by Covid-19, this technology can improve the lives of patients, the care provided by doctors, and the efficiency of health systems.❞
~ Dr. Peter Small, CMO, Hyfe
How does it do it?
Hyfe’s AI monitors the number of times a person coughs and the sound of the cough through any smartphone or other smart device.
This data collected over time provides increasingly more reliable information than a single visit to the doctor! By constantly listening and analyzing, it can detect patterns that might otherwise go unnoticed.
How big is this “big data” effort?
Hyfe maintains the largest cough dataset in the world. This means it can compare the sound of a patient’s cough with more than 400 million cough-like sounds from 83 countries across all continents.
The human brain doesn’t handle big numbers well. So, just to illustrate: if the average cough is 1 second long, that means it’d take more than 12 years to listen to them all.
Hyfe, meanwhile, can:
- listen to many things simultaneously
- index them all against user and location,
- use its ever-growing neural net to detect and illustrate patterns.
It’s so attentive, that it can learn to distinguish between different people’s coughs in the same household.
❝Companies like Google Health see even basic information such as getting an accurate count of the number of times a person coughs a day as a useful resource, and part of a larger need to collect and chronicle more health information to refine the way doctors diagnose disease and manage treatments in the future.❞
What are the public health implications?
The most obvious application is to note when there’s a spike in coughing, and see how such spikes grow and spread (if they do), to inform of contagion risks.
Another is to cross-reference it with data about local environmental allergens. Knowing how things like pollution and even pollen affect individuals differently could be helpful in identifying (and managing) chronic conditions like asthma.
What are the private health implications?
❝It’s going to transform the whole clinical approach for this common and chronic symptom. Patients will come in, have the data on how much they are coughing, and the physician can suggest a treatment based on that information to see if it makes the coughs better❞
~ Dr. Peter Small
Dr. Small’s colleague Dr. Cai, speaking for Google Health on this project, sees even more utility for diagnostics:
❝When I was in medical school, never ever did they teach us that we could listen to somebody cough and identify whether that person has TB (tuberculosis), COPD, or a tumor. But I keep seeing more and more studies of people coughing into a microphone, and an algorithm can detect whether somebody has TB with 95% specificity and sensitivity, or if someone has pneumonia or an exacerbation of COPD❞
~ Dr. Lawrence Cai
And the privacy implications?
Perhaps you don’t quite fancy the idea of not being able to cough without Google knowing about it. Hyfe’s software is currently opt-in, but…
If you cough near someone else’s Hyfe app, their app will recognize you’re not the app’s user, and start building a profile for you. Of course, that won’t be linked to your name, email address, or other IDs, as it would if you were the app’s user.
Hyfe will ask to connect to your social media, to collect more information about you and your friends.

Butter vs Margarine

Butter vs Margarine
Yesterday, we asked you for your (health-related) opinion on butter vs margarine, and got the above-depicted, below-described, set of responses:
- A little over 60% said butter is a health food and margarine is basically plastic with trans fats
- A little over 20% said that both are woeful and it’s better to avoid both
- A little over 10% said that margarine is a lighter option, and butter is a fast track to cardiovascular disease.
Comments included (we will summarize/paraphrase, for space):
- “…in moderation, though”
- “I’m vegan so I use vegan butter but I know it’s not great, so I use it sparingly”
- “butter is healthy if and only if it’s grass-fed”
- “margarine has unpronounceable ingredients”
To address those quickly:
- “…in moderation” is a stipulation with which one can rarely go too far wrong
- Same! Speaking for myself (your writer here, hi) and not for the company
- Grass-fed is indeed better; alas that so little of it is grass-fed, in the US!
- Butter contains eicosatrienoic acid, linolelaidic acid, and more*. Sometimes big words don’t mean that something is worse for the health, though!
So, what does the science say?
Butter is a health food: True or False?
True or False, depending on amount! Moderation is definitely key, but we’ll return to that (and why not to have more than a small amount of butter) later. But it is a rich source of many nutrients, iff it’s grass-fed, anyway.
The nutritional profile of something isn’t a thing that’s too contentious, so rather than take too much time on it, in this case we’ll point you back up to the scientific paper we linked above, or if you prefer a pop-science rendering, here’s a nice quick rundown:
7 Reasons to Switch to Grass-Fed Butter
Margarine is basically plastic with trans fats: True or False?
False and usually False now, respectively, contingently.
On the first part: chemically, it’s simply not “basically plastic” and everything in it is digestible
On the second part: it depends on the margarine, and here’s where it pays to read labels. Historically, margarines all used to be high in trans fats (which are indeed woeful for the health). Nowadays, since trans fats have such a (well-earned) bad press, there are increasingly many margarines with low (or no) trans fats, and depending on your country, it may be that all margarines no longer have such:
❝It’s a public health success story. Consumers no longer have to worry about reading product nutritional labels to see if they contain hydrogenated oils and trans fats. They can just know that they no longer do❞
Source: Margarines now nutritionally better than butter after hydrogenated oil ban
So this is one where the science is clear (trans fats are unequivocally bad), but the consumer information is not always (it may be necessary to read labels, to know whether a margarine is conforming to the new guidelines).
Butter is a fast track to cardiovascular disease: True or False?
True or False depending on amount. In moderation, predictably it’s not a big deal.
But for example, the World Health Organization recommends that saturated fats (of which butter is a generous source) make up no more than 10% of our calorie intake:
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
So if you have a 2000 kcal daily intake, that would mean consuming not more than 200 kcal from butter, which is approximately two tablespoons.
If you’d like a deeper look into the complexities of saturated fats (for and against), you might like our previous main feature specifically about such:
Can Saturated Fats Be Healthy?

As the U.S. Struggles With a Stillbirth Crisis, Australia Offers a Model for How to Do Better
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.

Series: Stillbirths:When Babies Die Before Taking Their First Breath
The U.S. has not prioritized stillbirth prevention, and American parents are losing babies even as other countries make larger strides to reduce deaths late in pregnancy.
The stillbirth of her daughter in 1999 cleaved Kristina Keneally’s life into a before and an after. It later became a catalyst for transforming how an entire country approaches stillbirths.
In a world where preventing stillbirths is typically far down the list of health care priorities, Australia — where Keneally was elected as a senator — has emerged as a global leader in the effort to lower the number of babies that die before taking their first breaths. Stillbirth prevention is embedded in the nation’s health care system, supported by its doctors, midwives and nurses, and touted by its politicians.
In 2017, funding from the Australian government established a groundbreaking center for research into stillbirths. The next year, its Senate established a committee on stillbirth research and education. By 2020, the country had adopted a national stillbirth plan, which combines the efforts of health care providers and researchers, bereaved families and advocacy groups, and lawmakers and government officials, all in the name of reducing stillbirths and supporting families. As part of that plan, researchers and advocates teamed up to launch a public awareness campaign. All told, the government has invested more than $40 million.
Meanwhile, the United States, which has a far larger population, has no national stillbirth plan, no public awareness campaign and no government-funded stillbirth research center. Indeed, the U.S. has long lagged behind Australia and other wealthy countries in a crucial measure: how fast the stillbirth rate drops each year.
According to the latest UNICEF report, the U.S. was worse than 151 countries in reducing its stillbirth rate between 2000 and 2021, cutting it by just 0.9%. That figure lands the U.S. in the company of South Sudan in Africa and doing slightly better than Turkmenistan in central Asia. During that period, Australia’s reduction rate was more than double that.
Definitions of stillbirth vary by country, and though both Australia and the U.S. mark stillbirths as the death of a fetus at 20 weeks or more of pregnancy, to fairly compare countries globally, international standards call for the use of the World Health Organization definition that defines stillbirth as a loss after 28 weeks. That puts the U.S. stillbirth rate in 2021 at 2.7 per 1,000 total births, compared with 2.4 in Australia the same year.
Every year in the United States, more than 20,000 pregnancies end in a stillbirth. Each day, roughly 60 babies are stillborn. Australia experiences six stillbirths a day.
Over the past two years, ProPublica has revealed systemic failures at the federal and local levels, including not prioritizing research, awareness and data collection, conducting too few autopsies after stillbirths and doing little to combat stark racial disparities. And while efforts are starting to surface in the U.S. — including two stillbirth-prevention bills that are pending in Congress — they lack the scope and urgency seen in Australia.
“If you ask which parts of the work in Australia can be done in or should be done in the U.S., the answer is all of it,” said Susannah Hopkins Leisher, a stillbirth parent, epidemiologist and assistant professor in the stillbirth research program at the University of Utah Health. “There’s no physical reason why we cannot do exactly what Australia has done.”
Australia’s goal, which has been complicated by the pandemic, is to, by 2025, reduce the country’s rate of stillbirths after 28 weeks by 20% from its 2020 rate. The national plan laid out the target, and it is up to each jurisdiction to determine how to implement it based on their local needs.
The most significant development came in 2019, when the Stillbirth Centre of Research Excellence — the headquarters for Australia’s stillbirth-prevention efforts — launched the core of its strategy, a checklist of five evidence-based priorities known as the Safer Baby Bundle. They include supporting pregnant patients to stop smoking; regular monitoring for signs that the fetus is not growing as expected, which is known as fetal growth restriction; explaining the importance of acting quickly if fetal movement changes or decreases; advising pregnant patients to go to sleep on their side after 28 weeks; and encouraging patients to talk to their doctors about when to deliver because in some cases that may be before their due date.
Officials estimate that at least half of all births in the country are covered by maternity services that have adopted the bundle, which focuses on preventing stillbirths after 28 weeks.
“These are babies whose lives you would expect to save because they would survive if they were born alive,” said Dr. David Ellwood, a professor of obstetrics and gynecology at Griffith University, director of maternal-fetal medicine at Gold Coast University Hospital and a co-director of the Stillbirth Centre of Research Excellence.
Australia wasn’t always a leader in stillbirth prevention.
In 2000, when the stillbirth rate in the U.S. was 3.3 per 1,000 total births, Australia’s was 3.7. A group of doctors, midwives and parents recognized the need to do more and began working on improving their data classification and collection to better understand the problem areas. By 2014, Australia published its first in-depth national report on stillbirth. Two years later, the medical journal The Lancet published the second report in a landmark series on stillbirths, and Australian researchers applied for the first grant from the government to create the stillbirth research center.
But full federal buy-in remained elusive.
As parent advocates, researchers, doctors and midwives worked to gain national support, they didn’t yet know they would find a champion in Keneally.
Keneally’s improbable journey began when she was born in Nevada to an American father and Australian mother. She grew up in Ohio, graduating from the University of Dayton before meeting the man who would become her husband and moving to Australia.
When she learned that her daughter, who she named Caroline, would be stillborn, she remembers thinking, “I’m smart. I’m educated. How did I let this happen? And why did nobody tell me this was a possible outcome?”
A few years later, in 2003, Keneally decided to enter politics. She was elected to the lower house of state parliament in New South Wales, of which Sydney is the capital. In Australia, newly elected members are expected to give a “first speech.” She was able to get through just one sentence about Caroline before starting to tear up.
As a legislator, Keneally didn’t think of tackling stillbirth as part of her job. There wasn’t any public discourse about preventing stillbirths or supporting families who’d had one. When Caroline was born still, all Keneally got was a book titled “When a Baby Dies.”
In 2009, Keneally became New South Wales’ first woman premier, a role similar to that of an American governor. Another woman who had suffered her own stillbirth and was starting a stillbirth foundation learned of Keneally’s experience. She wrote to Keneally and asked the premier to be the foundation’s patron.
What’s the point of being the first female premier, Keneally thought, if I can’t support this group?
Like the U.S., Australia had previously launched an awareness campaign that contributed to a staggering reduction in sudden infant death syndrome, or SIDS. But there was no similar push for stillbirths.
“If we can figure out ways to reduce SIDS,” Keneally said, “surely it’s not beyond us to figure out ways to reduce stillbirth.”
She lost her seat after two years and took a break from politics, only to return six years later. In 2018, she was selected to serve as a senator at Australia’s federal level.
Keneally saw this as her second chance to fight for stillbirth prevention. In the short period between her election and her inaugural speech, she had put everything in place for a Senate inquiry into stillbirth.
In her address, Keneally declared stillbirth a national public health crisis. This time, she spoke at length about Caroline.
“When it comes to stillbirth prevention,” she said, “there are things that we know that we’re not telling parents, and there are things we don’t know, but we could, if we changed how we collected data and how we funded research.”
The day of her speech, March 27, 2018, she and her fellow senators established the Select Committee on Stillbirth Research and Education.
Things moved quickly over the next nine months. Keneally and other lawmakers traveled the country holding hearings, listening to testimony from grieving parents and writing up their findings in a report released that December.
“The culture of silence around stillbirth means that parents and families who experience it are less likely to be prepared to deal with the personal, social and financial consequences,” the report said. “This failure to regard stillbirth as a public health issue also has significant consequences for the level of funding available for research and education, and for public awareness of the social and economic costs to the community as a whole.”
It would be easy to swap the U.S. for Australia in many places throughout the report. Women of Aboriginal and Torres Strait Islander backgrounds experienced double the rate of stillbirth of other Australian women; Black women in America are more than twice as likely as white women to have a stillbirth. Both countries faced a lack of coordinated research and corresponding funding, low autopsy rates following a stillbirth and poor public awareness of the problem.
The day after the report’s release, the Australian government announced that it would develop a national plan and pledged $7.2 million in funding for prevention. Nearly half was to go to education and awareness programs for women and their health care providers.
In the following months, government officials rolled out the Safer Baby Bundle and pledged another $26 million to support parents’ mental health after a loss.
Many in Australia see Keneally’s first speech as senator, in 2018, as the turning point for the country’s fight for stillbirth prevention. Her words forced the federal government to acknowledge the stillbirth crisis and launch the national action plan with bipartisan support.
Australia’s assistant minister for health and aged care, Ged Kearney, cited Keneally’s speech in an email to ProPublica where she noted that Australia has become a world leader in stillbirth awareness, prevention and supporting families after a loss.
“Kristina highlighted the power of women telling their story for positive change,” Kearney said, adding, “As a Labor Senator Kristina Keneally bravely shared her deeply personal story of her daughter Caroline who was stillborn in 1999. Like so many mothers, she helped pave the way for creating a more compassionate and inclusive society.”
Keneally, who is now CEO of Sydney Children’s Hospitals Foundation, said the number of stillbirths a day in Australia spurred the movement for change.
“Six babies a day,” Keneally said. “Once you hear that fact, you can’t unhear it.”
Australia’s leading stillbirth experts watched closely as the country moved closer to a unified effort. This was the moment for which they had been waiting.
“We had all the information needed, but that’s really what made it happen.” said Vicki Flenady, a perinatal epidemiologist, co-director of the Stillbirth Centre of Research Excellence based at the Mater Research Institute at the University of Queensland, and a lead author on The Lancet’s stillbirth series. “I don’t think there’s a person who could dispute that.”
Flenady and her co-director Ellwood had spent more than two decades focused on stillbirths. After establishing the center in 2017, they were now able to expand their team. As part of their work with the International Stillbirth Alliance, they reached out to other countries with a track record of innovation and evidence-based research: the United Kingdom, the Netherlands, Ireland. They modeled the Safer Baby Bundle after a similar one in the U.K., though they added some elements.
In 2019, the state of Victoria, home to Melbourne, was the first to implement the Safer Baby Bundle. But 10 months into the program, the effort had to be paused for several months because of the pandemic, which forced other states to cancel their launches altogether.
“COVID was a major disruption. We stopped and started,” Flenady said.
Still, between 2019 and 2021, participating hospitals across Victoria were able to reduce their stillbirth rate by 21%. That improvement has yet to be seen at the national level.
A number of areas are still working on implementing the bundle. Westmead Hospital, one of Australia’s largest hospitals, planned to wrap that phase up last month. Like many hospitals, Westmead prominently displays the bundle’s key messages in the colorful posters and flyers hanging in patient rooms and in the hallways. They include easy-to-understand slogans such as, “Big or small. Your baby’s growth matters,” and, “Sleep on your side when baby’s inside.”
As patients at Westmead wait for their names to be called, a TV in the waiting room plays a video on stillbirth prevention, highlighting the importance of fetal movement. If a patient is concerned their baby’s movements have slowed down, they are instructed to come in to be seen within two hours. The patient’s chart gets a colorful sticker with a 16-point checklist of stillbirth risk factors.
Susan Heath, a senior clinical midwife at Westmead, came up with the idea for the stickers. Her office is tucked inside the hospital’s maternity wing, down a maze of hallways. As she makes the familiar walk to her desk, with her faded hospital badge bouncing against her navy blue scrubs, it’s clear she is a woman on a mission. The bundle gives doctors and midwives structure and uniform guidance, she said, and takes stillbirth out of the shadows. She reminds her staff of how making the practices a routine part of their job has the power to change their patients’ lives.
“You’re trying,” she said, “to help them prevent having the worst day of their life.”
Christine Andrews, a senior researcher at the Stillbirth Centre who is leading an evaluation of the program’s effectiveness, said the national stillbirth rate beyond 28 weeks has continued to slowly improve.
“It is going to take a while until we see the stillbirth rate across the whole entire country go down,” Andrews said. “We are anticipating that we’re going to start to see a shift in that rate soon.”
As officials wait to receive and standardize the data from hospitals and states, they are encouraged by a number of indicators.
For example, several states are reporting increases in the detection of babies that aren’t growing as they should, a major factor in many late-gestation stillbirths. Many also have seen an increase in the number of pregnant patients who stopped smoking. Health care providers also are more consistently offering post-stillbirth investigations, such as autopsies.
In addition to the Safer Baby Bundle, the national plan also calls for raising awareness and reducing racial disparities. The improvements it recommends for bereavement care are already gaining global attention.
To fulfill those directives, Australia has launched a “Still Six Lives” public awareness campaign, has implemented a national stillbirth clinical care standard and has spent two years developing a culturally inclusive version of the Safer Baby Bundle for First Nations, migrant and refugee communities. Those resources, which were recently released, incorporated cultural traditions and used terms like Stronger Bubba Born for the bundle and “sorry business babies,” which is how some Aboriginal and Torres Strait Islander women refer to stillbirth. There are also audio versions for those who can’t or prefer not to read the information.
In May, nearly 50 people from the state of Queensland met in a large hotel conference room. Midwives, doctors and nurses sat at round tables with government officials, hospital administrators and maternal and infant health advocates. Some even wore their bright blue Safer Baby T-shirts.
One by one, they discussed their experiences implementing the Safer Baby Bundle. One midwifery group was able to get more than a third of its patients to stop smoking between their first visit and giving birth.
Officials from a hospital in one of the fastest-growing areas in the state discussed how they carefully monitored for fetal growth restriction.
And staff from another hospital, which serves many low-income and immigrant patients, described how 97% of pregnant patients who said their baby’s movements had decreased were seen for additional monitoring within two hours of voicing their concern.
As the midwives, nurses and doctors ticked off the progress they were seeing, they also discussed the fear of unintended consequences: higher rates of premature births or increased admissions to neonatal intensive care units. But neither, they said, has materialized.
“The bundle isn’t causing any harm and may be improving other outcomes, like reducing early-term birth,” Flenady said. “I think it really shows a lot of positive impact.”
As far behind as the U.S. is in prioritizing stillbirth prevention, there is still hope.
Dr. Bob Silver, who co-authored a study that estimated that nearly 1 in 4 stillbirths are potentially preventable, has looked to the international community as a model. Now, he and Leisher — the University of Utah epidemiologist and stillbirth parent — are working to create one of the first stillbirth research and prevention centers in the U.S. in partnership with stillbirth leaders from Australia and other countries. They hope to launch next year.
“There’s no question that Australia has done a better job than we have,” said Silver, who is also chair of the University of Utah Health obstetrics and gynecology department. “Part of it is just highlighting it and paying attention to it.”
It’s hard to know what parts of Australia’s strategy are making a difference — the bundle as a whole, just certain elements of it, the increased stillbirth awareness across the country, or some combination of those things. Not every component has been proven to decrease stillbirth.
The lack of U.S. research on the issue has made some cautious to adopt the bundle, Silver said, but it is clear the U.S. can and should do more.
There comes a point when an issue is so critical, Silver said, that people have to do the best they can with the information that they have. The U.S. has done that with other problems, such as maternal mortality, he said, though many of the tactics used to combat that problem have not been proven scientifically.
“But we’ve decided this problem is so bad, we’re going to try the things that we think are most likely to be helpful,” Silver said.
After more than 30 years of working on stillbirth prevention, Silver said the U.S. may be at a turning point. Parents’ voices are getting louder and starting to reach lawmakers. More doctors are affirming that stillbirths are not inevitable. And pressure is mounting on federal institutions to do more.
Of the two stillbirth prevention bills in Congress, one already sailed through the Senate. The second bill, the Stillbirth Health Improvement and Education for Autumn Act, includes features that also appeared in Australia’s plan, such as improving data, increasing awareness and providing support for autopsies.
And after many years, the National Institutes of Health has turned its focus back to stillbirths. In March, it released a report with a series of recommendations to reduce the nation’s stillbirth rate that mirror ProPublica’s reporting about some of the causes of the crisis. Since then, it has launched additional groups to begin to tackle three critical angles: prevention, data and bereavement. Silver co-chairs the prevention group.
In November, more than 100 doctors, parents and advocates gathered for a symposium in New York City to discuss everything from improving bereavement care in the U.S to tackling racial disparities in stillbirth. In 2022, after taking a page out of the U.K.’s book, the city’s Mount Sinai Hospital opened the first Rainbow Clinic in the U.S., which employs specific protocols to care for people who have had a stillbirth.
But given the financial resources in the U.S. and the academic capacity at American universities and research institutions, Leisher and others said federal and state governments aren’t doing nearly enough.
“The U.S. is not pulling its weight in relation either to our burden or to the resources that we have at our disposal,” she said. “We’ve got a lot of babies dying, and we’ve got a really bad imbalance of who those babies are as well. And yet we look at a country with a much smaller number of stillbirths who is leading the world.”
“We can do more. Much more. We’re just not,” she added. “It’s unacceptable.”

The Other Ways To Look After Your Joints
When it comes to joint health, most people have two quick go-to items:
- Stretching
- Supplements like omega-3 and glucosamine sulfate
Stretching, and specifically, mobility exercises, are important! We’ll have to do a main feature on these sometime soon. But for today, we’ll just say: yes, gentle daily stretches go a long way, as does just generally moving more.
And, those supplements are not without their merits. For example:
- Effect of omega-3 on painful symptoms of patients with osteoarthritis of the synovial joints: systematic review and meta-analysis
- Glucosamine sulfate in the treatment of knee osteoarthritis symptoms: a randomized, double-blind, placebo-controlled study using acetaminophen as a side comparator
Of those, glucosamine sulfate may have an extra benefit in now just alleviating the symptoms, but also slowing the progression of degenerative joint conditions (like arthritis of various kinds). This is something it shares with chondroitin sulfate:
Effect of glucosamine or chondroitin sulfate on the osteoarthritis progression: a meta-analysis
An unlikely extra use for the humble cucumber…
As it turns out, cucumber extract beats glucosamine and chondroitin by 200%, at 1/135th of the dose.
You read that right, and it’s not a typo. See for yourself:
Reduce inflammation, have happier joints
Joint pain and joint degeneration in general is certainly not just about inflammation; there is physical wear-and-tear too. But combatting inflammation is important, and turmeric, which we’ve done a main feature on before, is a potent helper in this regard:
See also: Keep Inflammation At Bay
(a whole list of tips for, well, keeping inflammation at bay)
About that wear-and-tear…
Your bones and joints are made of stuff, and that stuff needs to be replaced. As we get older, the body typically gets worse at replacing it in a timely and efficient fashion. We can help it do its job, by giving it more of the stuff it needs.
And what stuff is that?
Well, minerals like calcium and phosphorus are important, but a lot is also protein! Specifically, collagen. We did a main feature on this before, which is good, as it’d take us a lot of space to cover all the benefits here:
We Are Such Stuff As Fish Are Made Of
Short version? People take collagen for their skin, but really, its biggest benefit is for our bones and joints!
Wrap up warmly and… No wait, skip that.
If you have arthritis, you may indeed “feel it in your bones” when the weather changes. But the remedy for that is not to try to fight it, but rather, to strengthen your body’s ability to respond to it.
The answer? Cryotherapy, with ice baths ranking top:
- Effects of an Exercise Program and Cold-Water Immersion Recovery in Patients with Rheumatoid Arthritis (RA): Feasibility Study
- Effectiveness of home-based conventional exercise and cryotherapy on daily living activities in patients with knee osteoarthritis: A randomized controlled clinical trial
- Local Cryotherapy, Comparison of Cold Air and Ice Massage on Pain and Handgrip Strength in Patients with Rheumatoid Arthritis
Note that this can be just localized, so for example if the problem joints are your wrists, a washing-up bowl with water and ice will do just nicely.
Note also that, per that last study, a single session will only alleviate the pain, not the disease itself. For that (per the other studies) more sessions are required.
We did a main feature about cryotherapy a while back, and it explains how and why it works:
A Cold Shower A Day Keeps The Doctor Away?
Take care!
