“Osteoporosis” and “break” often don’t go well together, but here they do. So, what’s the breakthrough here?
There isn’t one, honestly. But if we overlook the marketing choices and focus on the book itself, the content here is genuinely good:
The book offers a comprehensive multivector approach to combatting osteoporosis, e.g:
- Diet
- Exercise
- Other lifestyle considerations
- Supplements
- Hormones
- Drugs
The author considers drugs a good and important tool for some people with osteoporosis, but not most. The majority of people, he considers, will do better without drugs—by tackling things more holistically.
The advice here is sound and covers all reasonable angles without getting hung up on the idea of there being a single magical solution for all.
Bottom line: if you’re looking for a book that’s a one-stop-shop for strategies against osteoporosis, this is a good option.

When supplies resume, should governments subsidise drugs like Ozempic for weight loss? We asked 5 experts

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.
You’ve no doubt heard of Ozempic but have you heard of Wegovy? They’re both brand names of the drug semaglutide, which is currently in short supply worldwide.
Ozempic is a lower dose of semaglutide, and is approved and used to treat diabetes in Australia. Wegovovy is approved to treat obesity but is not yet available in Australia. Shortages of both drugs are expected to last throughout 2024.
Both drugs are expensive. But Ozempic is listed on Australia’s Pharmaceutical Benefits Schedule (PBS), so people with diabetes can get a three-week supply for A$31.60 ($7.70 for concession card holders) rather than the full price ($133.80).
Wegovy isn’t listed on the PBS to treat obesity, meaning when it becomes available, users will need to pay the full price. But should the government subsidise it?
Wegovy’s manufacturer will need to make the case for it to be added to the PBS to an independent advisory committee. The company will need to show Wegovy is a safe, clinically effective and cost-effective treatment for obesity compared to existing alternatives.
In the meantime, we asked five experts: when supplies resume, should governments subsidise drugs like Ozempic for weight loss?
Four out of five said yes
This is the last article in The Conversation’s Ozempic series. Read the other articles here.

Why 7 Hours 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.
How Sleep-Deprived Are You, Really?
This is Dr. Matthew Walker. He’s a neuroscientist and sleep specialist, and is the Director of the Center for Human Sleep Science at UC Berkeley’s Department of Psychology. He’s also the author of the international bestseller “Why We Sleep”.
What does he want us to know?
Sleep deprivation is more serious than many people think it is. After about 16 hours without sleep, the brain begins to fail, and needs more than 7 hours of sleep to “reset” cognitive performance.
Note: note “seven or more”, but “more than seven”.
After ten days with only 7 hours sleep (per day), Dr. Walker points out, the brain is as dysfunctional as it would be after going without sleep for 24 hours.
Here’s the study that sparked a lot of Dr. Walker’s work:
Importantly, in Dr. Walker’s own words:
❝Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping❞
~ Dr. Matthew Walker
See also: Why You Probably Need More Sleep
Furthermore: the sleep-deprived mind is unaware of how sleep-deprived it is.
You know how a drunk person thinks they can drive safely? It’s like that.
You do not know how sleep-deprived you are, when you are sleep-deprived!
For example:
❝(60.7%) did not signal sleepiness before a sleep fragment occurred in at least one of the four MWT trials❞
Source: Sleepiness is not always perceived before falling asleep in healthy, sleep-deprived subjects
Sleep efficiency matters
With regard to the 7–9 hours band for optimal health, Dr. Walker points out that the sleep we’re getting is not always the sleep we think we’re getting:
❝Assuming you have a healthy sleep efficiency (85%), to sleep 9 hours in terms of duration (i.e. to be a long-sleeper), you would need to be consistently in bed for 10 hours and 36 minutes a night. ❞
~ Dr. Matthew Walker
At the bottom end of that, by the way, doing the same math: to get only the insufficient 7 hours sleep discussed earlier, a with a healthy 85% sleep efficiency, you’d need to be in bed for 8 hours and 14 minutes per night.
The unfortunate implication of this: if you are consistently in bed for 8 hours and 14 minutes (or under) per night, you are not getting enough sleep.
“But what if my sleep efficiency is higher than 85%?”
It shouldn’t be.If your sleep efficiency is higher than 85%, you are sleep-deprived and your body is having to enforce things.

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

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.”

Can Saturated Fats Be Healthy?

Saturated Fat: What’s The Truth?
We asked you for your health-related opinion of saturated fat, and got the above-pictured, below-described, set of results.
- Most recorded votes were for “Saturated fat is good, but only some sources, and/or in moderation”
- This is an easy one to vote for, because of the “and/or in moderation” part, which tends to be a “safe bet” for most things.
- Next most popular was “Saturated fat is terrible for the health and should be avoided”
- About half as many recorded votes were for “I’m not actually sure what makes saturated fat different”, which is a very laudable option to click. Admitting when we don’t know things (and none of us know everything) is a very good first step to learning about them!
- Fewest recorded votes were for “Saturated fat is the best source of energy; we should get plenty”.
So, what does the science say?
First, a bit of physics, chemistry, and biology
You may be wondering what, exactly, saturated fats are “saturated” with. That’s a fair question, so…
All fats have a molecular structure made up of carbon, hydrogen, and oxygen atoms. Saturated fats are saturated with hydrogen, and thus have only single bonds between carbon atoms (unsaturated fats have at least one double-bond between carbon atoms).
The observable effect this has on them, is that fats that are saturated with hydrogen are solid at room temperature, whereas unsaturated fats are liquid at room temperature. Their different properties also make for different interactions inside the human body, including how likely or not they are to (for example) clog arteries.
See also: Could fat in your bloodstream cause blood clots?
Saturated fat is the best source of energy; we should get plenty: True or False?
False, in any reasonable interpretation, anyway. That is to say, if your idea of “plenty” is under 13g (e.g: two tablespoons of butter, and no saturated fat from other sources, e.g. meat) per day, then yes, by all means feel free to eat plenty. More than that, though, and you might want to consider trimming it down a bit.
The American Heart Association has this to say:
❝When you hear about the latest “diet of the day” or a new or odd-sounding theory about food, consider the source.
The American Heart Association recommends limiting saturated fats, which are found in butter, cheese, red meat and other animal-based foods, and tropical oils.
Decades of sound science has proven it can raise your “bad” cholesterol and put you at higher risk for heart disease.❞
Source: The American Heart Association Diet and Lifestyle Recommendations on Saturated Fat
The British Heart Foundation has a similar statement:
❝Despite what you read in the media, our advice is clear: replace saturated fats with unsaturated fats and avoid trans fats. Saturated fat is the kind of fat found in butter, lard, ghee, fatty meats and cheese. This is linked to an increased risk of heart and circulatory disease❞
Source: British Heart Foundation: What does fat do and what is saturated fat?
As for the World Health Organization:
❝1. WHO strongly recommends that adults and children reduce saturated fatty acid intake to 10% of total energy intake
2. WHO suggests further reducing saturated fatty acid intake to less than 10% of total energy intake
3. WHO strongly recommends replacing saturated fatty acids in the diet with polyunsaturated fatty acids; monounsaturated fatty acids from plant sources; or carbohydrates from foods containing naturally occurring dietary fibre, such as whole grains, vegetables, fruits and pulses.❞
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
Please note, organizations such as the AHA, the BHF, and the WHO are not trying to sell us anything, and just would like us to not die of heart disease, the world’s #1 killer.
As for “the best source of energy”…
We evolved to eat (much like our nearest primate cousins) a diet consisting mostly of fruits and other edible plants, with a small supplementary amount of animal-source protein and fats.
That’s not to say that because we evolved that way we have to eat that way—we are versatile omnivores. But for example, we are certainly not complete carnivores, and would quickly sicken and die if we tried to live on only meat and animal fat (we need more fiber, more carbohydrates, and many micronutrients that we usually get from plants)
The closest that humans tend to come to doing such is the ketogenic diet, which focuses on a high fat, low carbohydrate imbalance, to promote ketosis, in which the body burns fat for energy.
The ketogenic diet does work, and/but can cause a lot of health problems if a lot of care is not taken to avoid them.
See for example: 7 Keto Risks To Keep In Mind
Saturated fat is terrible for the health and should be avoided: True or False?
False, if we are talking about “completely”.
Firstly, it’s practically impossible to cut out all saturated fats, given that most dietary sources of fat are a mix of saturated, unsaturated (mono- and poly-), and trans fats (which are by far the worst, but beyond the scope of today’s main feature).
Secondly, a lot of research has been conducted and found insignificant or inconclusive results, in cases where saturated fat intake was already within acceptable levels (per the recommendations we mentioned earlier), and then cut down further.
Rather than fill up the newsletter with individual studies of this kind here’s a high-quality research review, looking at 19 meta-analyses, each of those meta-analyses having looked at many studies:
Dietary saturated fat and heart disease: a narrative review
Saturated fat is good, but only some sources, and/or in moderation: True or False?
True! The moderation part is easy to guess, so let’s take a look at the “but only some sources”.
We were not able to find any convincing science to argue for health-based reasons to favor plant- or animal-sourced saturated fat. However…
Not all saturated fats are created equal (there are many kinds), and also many of the foods containing them have additional nutrients, or harmful compounds, that make a big difference to overall health, when compared gram-for-gram in terms of containing the same amount of saturated fat.
For example:
- Palm oil’s saturated fat contains a disproportionate amount of palmitic acid, which raises LDL (“bad” cholesterol) without affecting HDL (“good” cholesterol), thus having an overall heart-harmful effect.
- Most animal fats contain a disproportionate amount of stearic acid, which has statistically insignificant effects on LDL and HDL levels, and thus is broadly considered “heart neutral” (in moderation!)
- Coconut oil’s saturated fat contains a disproportionate amount of lauric acid, which raises total cholesterol, but mostly HDL without affecting LDL, thus having an overall heart-beneficial effect (in moderation!)

ADHD For Smart Ass Women – by Tracy Otsuka
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’ve reviewed books about ADHD in adults before, what makes this one different? It’s the wholly female focus. Which is not to say some things won’t apply to men too, they will.
But while most books assume a male default unless it’s “bikini zone” health issues, this one is written by a woman for women focusing on the (biological and social) differences in ADHD for us.
A strength of the book is that it neither seeks to:
- over-medicalize things in a way that any deviation from the norm is inherently bad and must be fixed, nor
- pretend that everything’s a bonus, that we are superpowered and beautiful and perfect and capable and have no faults that might ever need addressing actually
…instead, it gives a good explanation of the ins and outs of ADHD in women, the strengths and weaknesses that this brings, and good solid advice on how to play to the strengths and reduce (or at least work around) the weaknesses.
Bottom line: this book has been described as “ADHD 2.0 (a very popular book that we’ve reviewed previously), but for women”, and it deserves that.
