What Omega-3 Fatty Acids Really Do For Us
Shockingly, we’ve not previously covered this in a main feature here at 10almonds… Mostly we tend to focus on less well-known supplements. However, in this case, the supplement may be well known, while some of its benefits, we suspect, may come as a surprise.
So…
What is it?
In this case, it’s more of a “what are they?”, because omega-3 fatty acids come in multiple forms, most notably:
- Alpha-linoleic acid (ALA)
- Eicosapentaenoic acid (EPA)
- Docosahexanoic acid (DHA)
ALA is most readily found in certain seeds and nuts (chia seeds and walnuts are top contenders), while EPA and DHA are most readily found in certain fish (hence “cod liver oil” being a commonly available supplement, though actually cod aren’t even the best source—salmon and mackerel are better; cod is just cheaper to overfish, making it the cheaper supplement to manufacture).
Which of the three is best, or do we need them all?
There are two ways of looking at this:
- ALA is sufficient alone, because it is a precursor to EPA and DHA, meaning that the body will take ALA and convert it into EPA and DHA as required
- EPA and DHA are superior because they’re already in the forms the body will use, which makes them more efficient
As with most things in health, diversity is good, so you really can’t go wrong by getting some from each source.
Unless you have an allergy to fish or nuts, in which case, definitely avoid those!
What do omega-3 fatty acids do for us, according to actual research?
Against inflammation
Most people know it’s good for joints, as this is perhaps what it’s most marketed for. Indeed, it’s good against inflammation of the joints (and elsewhere), and autoimmune diseases in general. So this means it is indeed good against common forms of arthritis, amongst others:

Against menstrual pain
Linked to the above-referenced anti-inflammatory effects, omega-3s were also found to be better than ibuprofen for the treatment of severe menstrual pain:

Against cognitive decline
This one’s a heavy-hitter. It’s perhaps to be expected of something so good against inflammation (bearing in mind that, for example, a large part of Alzheimer’s is effectively a form of inflammation of the brain); as this one’s so important and such a clear benefit, here are three particularly illustrative studies:
- Inadequate supply of vitamins and DHA in the elderly: implications for brain aging and Alzheimer-type dementia
- Fish consumption and cognitive decline with age in a large community study
- Fish consumption, long-chain omega-3 fatty acids and risk of cognitive decline or Alzheimer disease
Against heart disease
The title says it all in this one:
But what about in patients who do have heart disease?
Mozaffarian and Wu did a huge meta-review of available evidence, and found that in fact, of all the studied heart-related effects, reducing mortality rate in cases of cardiovascular disease was the single most well-evidenced benefit:
How much should we take?
There’s quite a bit of science on this, and—which is unusual for something so well-studied—not a lot of consensus.
However, to summarize the position of the academy of nutrition and dietetics on dietary fatty acids for healthy adults, they recommend a minimum of 250–500 mg combined EPA and DHA each day for healthy adults. This can be obtained from about 8 ounces (230g) of fatty fish per week, for example.
If going for ALA, on the other hand, the recommendation becomes 1.1g/day for women or 1.6g/day for men.

Federal Panel Prescribes New Mental Health Strategy To Curb Maternal Deaths
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.
BRIDGEPORT, Conn. — Milagros Aquino was trying to find a new place to live and had been struggling to get used to new foods after she moved to Bridgeport from Peru with her husband and young son in 2023.
When Aquino, now 31, got pregnant in May 2023, “instantly everything got so much worse than before,” she said. “I was so sad and lying in bed all day. I was really lost and just surviving.”
Aquino has lots of company.
Perinatal depression affects as many as 20% of women in the United States during pregnancy, the postpartum period, or both, according to studies. In some states, anxiety or depression afflicts nearly a quarter of new mothers or pregnant women.
Many women in the U.S. go untreated because there is no widely deployed system to screen for mental illness in mothers, despite widespread recommendations to do so. Experts say the lack of screening has driven higher rates of mental illness, suicide, and drug overdoses that are now the leading causes of death in the first year after a woman gives birth.
“This is a systemic issue, a medical issue, and a human rights issue,” said Lindsay R. Standeven, a perinatal psychiatrist and the clinical and education director of the Johns Hopkins Reproductive Mental Health Center.
Standeven said the root causes of the problem include racial and socioeconomic disparities in maternal care and a lack of support systems for new mothers. She also pointed a finger at a shortage of mental health professionals, insufficient maternal mental health training for providers, and insufficient reimbursement for mental health services. Finally, Standeven said, the problem is exacerbated by the absence of national maternity leave policies, and the access to weapons.
Those factors helped drive a 105% increase in postpartum depression from 2010 to 2021, according to the American Journal of Obstetrics & Gynecology.
For Aquino, it wasn’t until the last weeks of her pregnancy, when she signed up for acupuncture to relieve her stress, that a social worker helped her get care through the Emme Coalition, which connects girls and women with financial help, mental health counseling services, and other resources.
Mothers diagnosed with perinatal depression or anxiety during or after pregnancy are at about three times the risk of suicidal behavior and six times the risk of suicide compared with mothers without a mood disorder, according to recent U.S. and international studies in JAMA Network Open and The BMJ.
The toll of the maternal mental health crisis is particularly acute in rural communities that have become maternity care deserts, as small hospitals close their labor and delivery units because of plummeting birth rates, or because of financial or staffing issues.
This week, the Maternal Mental Health Task Force — co-led by the Office on Women’s Health and the Substance Abuse and Mental Health Services Administration and formed in September to respond to the problem — recommended creating maternity care centers that could serve as hubs of integrated care and birthing facilities by building upon the services and personnel already in communities.
The task force will soon determine what portions of the plan will require congressional action and funding to implement and what will be “low-hanging fruit,” said Joy Burkhard, a member of the task force and the executive director of the nonprofit Policy Center for Maternal Mental Health.
Burkhard said equitable access to care is essential. The task force recommended that federal officials identify areas where maternity centers should be placed based on data identifying the underserved. “Rural America,” she said, “is first and foremost.”
There are shortages of care in “unlikely areas,” including Los Angeles County, where some maternity wards have recently closed, said Burkhard. Urban areas that are underserved would also be eligible to get the new centers.
“All that mothers are asking for is maternity care that makes sense. Right now, none of that exists,” she said.
Several pilot programs are designed to help struggling mothers by training and equipping midwives and doulas, people who provide guidance and support to the mothers of newborns.
In Montana, rates of maternal depression before, during, and after pregnancy are higher than the national average. From 2017 to 2020, approximately 15% of mothers experienced postpartum depression and 27% experienced perinatal depression, according to the Montana Pregnancy Risk Assessment Monitoring System. The state had the sixth-highest maternal mortality rate in the country in 2019, when it received a federal grant to begin training doulas.
To date, the program has trained 108 doulas, many of whom are Native American. Native Americans make up 6.6% of Montana’s population. Indigenous people, particularly those in rural areas, have twice the national rate of severe maternal morbidity and mortality compared with white women, according to a study in Obstetrics and Gynecology.
Stephanie Fitch, grant manager at Montana Obstetrics & Maternal Support at Billings Clinic, said training doulas “has the potential to counter systemic barriers that disproportionately impact our tribal communities and improve overall community health.”
Twelve states and Washington, D.C., have Medicaid coverage for doula care, according to the National Health Law Program. They are California, Florida, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, Oklahoma, Oregon, Rhode Island, and Virginia. Medicaid pays for about 41% of births in the U.S., according to the Centers for Disease Control and Prevention.
Jacqueline Carrizo, a doula assigned to Aquino through the Emme Coalition, played an important role in Aquino’s recovery. Aquino said she couldn’t have imagined going through such a “dark time alone.” With Carrizo’s support, “I could make it,” she said.
Genetic and environmental factors, or a past mental health disorder, can increase the risk of depression or anxiety during pregnancy. But mood disorders can happen to anyone.
Teresa Martinez, 30, of Price, Utah, had struggled with anxiety and infertility for years before she conceived her first child. The joy and relief of giving birth to her son in 2012 were short-lived.
Without warning, “a dark cloud came over me,” she said.
Martinez was afraid to tell her husband. “As a woman, you feel so much pressure and you don’t want that stigma of not being a good mom,” she said.
In recent years, programs around the country have started to help doctors recognize mothers’ mood disorders and learn how to help them before any harm is done.
One of the most successful is the Massachusetts Child Psychiatry Access Program for Moms, which began a decade ago and has since spread to 29 states. The program, supported by federal and state funding, provides tools and training for physicians and other providers to screen and identify disorders, triage patients, and offer treatment options.
But the expansion of maternal mental health programs is taking place amid sparse resources in much of rural America. Many programs across the country have run out of money.
The federal task force proposed that Congress fund and create consultation programs similar to the one in Massachusetts, but not to replace the ones already in place, said Burkhard.
In April, Missouri became the latest state to adopt the Massachusetts model. Women on Medicaid in Missouri are 10 times as likely to die within one year of pregnancy as those with private insurance. From 2018 through 2020, an average of 70 Missouri women died each year while pregnant or within one year of giving birth, according to state government statistics.
Wendy Ell, executive director of the Maternal Health Access Project in Missouri, called her service a “lifesaving resource” that is free and easy to access for any health care provider in the state who sees patients in the perinatal period.
About 50 health care providers have signed up for Ell’s program since it began. Within 30 minutes of a request, the providers can consult over the phone with one of three perinatal psychiatrists. But while the doctors can get help from the psychiatrists, mental health resources for patients are not as readily available.
The task force called for federal funding to train more mental health providers and place them in high-need areas like Missouri. The task force also recommended training and certifying a more diverse workforce of community mental health workers, patient navigators, doulas, and peer support specialists in areas where they are most needed.
A new voluntary curriculum in reproductive psychiatry is designed to help psychiatry residents, fellows, and mental health practitioners who may have little or no training or education about the management of psychiatric illness in the perinatal period. A small study found that the curriculum significantly improved psychiatrists’ ability to treat perinatal women with mental illness, said Standeven, who contributed to the training program and is one of the study’s authors.
Nancy Byatt, a perinatal psychiatrist at the University of Massachusetts Chan School of Medicine who led the launch of the Massachusetts Child Psychiatry Access Program for Moms in 2014, said there is still a lot of work to do.
“I think that the most important thing is that we have made a lot of progress and, in that sense, I am kind of hopeful,” Byatt said.

Savor: Mindful Eating, Mindful Life – by Thich Nhat Hanh and Dr. Lilian Cheung
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 talked about mindful eating before at 10almonds, so here’s a book about it. You may wonder how much there is to say!
As it happens, there’s quite a bit. The authors, a Buddhist monk (Hanh) and a Harvard nutritionist (Dr. Cheung) explore the role of mindful eating in our life.
There is an expectation that we the reader want to lose weight. If we don’t, those parts of the book will be a “miss” for us, but still contain plenty of other value.
Most of the same advices can be applied equally to other aspects of health, in any case. A lot of that comes from the book’s Buddhist principles, including the notion that:
- We are experiencing suffering
- Suffering has a cause
- What has a cause can have an end
- The way to this end is mindfulness
As such, the process itself is also mindfulness all the way through:
- To be mindful of our suffering (and not let it become background noise to be ignored)
- To be mindful of the cause of our suffering (rather than dismissing it as just how things are)
- To be mindful of how to address that, and thus end the suffering (rather than despairing in inaction)
- To engage mindfully in the process of doing so (and thus not fall into the trap of thinking “job done”)
And, as for Dr. Cheung? She also has input throughout, with practical advice about the more scientific side of rethinking one’s diet.
Bottom line: this is an atypical book, and/but perhaps an important one. Certainly, at the very least it may be one to try if more conventional approaches have failed!

Lacking Motivation? Science Has The Answer
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 Science Of Motivation (And How To Use It To Your Advantage)
When we do something rewarding, our brain gets a little (or big!) spike of dopamine. Dopamine is popularly associated with pleasure—which is fair— but there’s more to it than this.
Dopamine is also responsible for motivation itself, as a prime mover before we do the thing that we find rewarding. If we eat a banana, and enjoy it, perhaps because our body needed the nutrients from it, our brain gets a hit of dopamine.
(and not because bananas contain dopamine; that dopamine is useful for the body, but can’t pass the blood-brain barrier to have an effect on the brain)
So where does the dopamine in our brain come from? That dopamine is made in the brain itself.
Key Important Fact: the brain produces dopamine when it expects an activity to be rewarding.
If you take nothing else away from today’s newsletter, let it be this!
It makes no difference if the activity is then not rewarding. And, it will keep on motivating you to do something it anticipated being rewarding, no matter how many times the activity disappoints, because it’ll remember the very dopamine that it created, as having been the reward.
To put this into an example:
- How often have you spent time aimlessly scrolling social media, flitting between the same three apps, or sifting through TV channels when “there’s nothing good on to watch”?
- And how often did you think afterwards “that was a good and rewarding use of my time; I’m glad I did that”?
In reality, whatever you felt like you were in search of, you were really in search of dopamine. And you didn’t find it, but your brain did make some, just enough to keep you going.
Don’t try to “dopamine detox”, though.
While taking a break from social media / doomscrolling the news / mindless TV-watching can be a great and healthful idea, you can’t actually “detox” from a substance your body makes inside itself.
Which is fortunate, because if you could, you’d die, horribly and miserably.
If you could “detox” completely from dopamine, you’d lose all motivation, and also other things that dopamine is responsible for, including motor control, language faculties, and critical task analysis (i.e. planning).
This doesn’t just mean that you’d not be able to plan a wedding; it also means:
- you wouldn’t be able to plan how to get a drink of water
- you wouldn’t have any motivation to get water even if you were literally dying of thirst
- you wouldn’t have the motor control to be able to physically drink it anyway
Read: Dopamine and Reward: The Anhedonia Hypothesis 30 years on
(this article is deep and covers a lot of ground, but is a fascinating read if you have time)
Note: if you’re wondering why that article mentions schizophrenia so much, it’s because schizophrenia is in large part a disease of having too much dopamine.
Consequently, antipsychotic drugs (and similar) used in the treatment of schizophrenia are generally dopamine antagonists, and scientists have been working on how to treat schizophrenia without also crippling the patient’s ability to function.
Do be clever about how you get your dopamine fix
Since we are hardwired to crave dopamine, and the only way to outright quash that craving is by inducing anhedonic depression, we have to leverage what we can’t change.
The trick is: question how much your motivation aligns with your goals (or doesn’t).
So if you feel like checking Facebook for the eleventieth time today, ask yourself: “am I really looking for new exciting events that surely happened in the past 60 seconds since I last checked, or am I just looking for dopamine?”
You might then realize: “Hmm, I’m actually just looking for dopamine, and I’m not going to find it there”
Then, pick something else to do that will actually be more rewarding. It helps if you make a sort of dopa-menu in advance, of things to pick from. You can keep this as a list on your phone, or printed and pinned up near your computer.
Examples might be: Working on that passion project of yours, or engaging in your preferred hobby. Or spending quality time with a loved one. Or doing housework (surprisingly not something we’re commonly motivated-by-default to do, but actually is rewarding when done). Or exercising (same deal). Or learning that language on Duolingo (all those bells and whistles the app has are very much intentional dopamine-triggers to make it addictive, but it’s not a terrible outcome to be addicted to learning!).
Basically… Let your brain’s tendency to get led astray work in your favor, by putting things in front of it that will lead you in good directions.
Things for your health and/or education are almost always great things to allow yourself the “ooh, shiny” reaction and pick them up, try something new, etc.

The CBT Workbook for Mental Health – by Dr. Simon Rego & Sarah Fader
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 have often reviewed psychology books here with a note saying “and no, it’s not just a book of the standard CBT techniques that you probably already know”.
So today, this one’s for anyone who was ever thinking “but I don’t know the standard CBT techniques and I would like to know them!”.
The authors outline specific solutions to many common quantifiable problems, with simple exercises that are well-explained and easy to implement.
Cognitive Behavioral Therapy (CBT) is not a panacea, but for the things it can be used for, it’s very effective and is a very good “first thing to reach for” to see if it works, because its success rate for a lot of problems is very high.
What kinds of things is this book most likely to help with? A lot of common forms of stress, anxiety, self-esteem issues, cravings, shame, and relationship issues. Other things too, but we can’t list everything and that list already covers a lot of very high-incidence stuff.
Bottom line: if CBT isn’t something already in your toolbox, this book will help you add all its best tips and tricks.

Healthy Living in a Contaminated World – by Dr. Donald Hoernschemeyer
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.
There’s a lot going on here, as this book tackles very many kinds of common contaminants, from waste products and industrial chemicals (such as from fracking), pesticides that are banned in most places but not the US, smog and soot from coal and oil power, mercury and other heavy metals, dioxins, Teflon and its close relatives, phthalates, BPA, and other things again regulated out of use in many countries but not entirely in the US (which bans them only in some things, like baby bottles), drinking water issues of various kinds, and much more.
Indeed, there’s a whole chapter on the US and international regulation of toxic substances; the problem is often that on a political level, the same people who are against nebulous “chemicals” are also against environmentalist regulations that would ban them. This is mostly not a political book though, and rather is chiefly a book of chemistry (the author’s field).
It does also cover the medical maladies associated with various contaminants, while the bulk of the data is on the chemistry side of such things as “elimination times for toxic chemicals”, “amounts of pesticides in fruit and vegetables”, “antibiotics and hormones used in animal agriculture”, and so forth.
The style is dense, and/but it is clear the author has made an effort to not be too dry. Still, this is not a fun read; it’s depressing in content and the style is more suited to academia. There are appendices containing glossaries and acronym tables, but reading front-to-back, there’s a lot that’s not explained so unless you also are a PhD chemist, chances are you’ll be needing to leaf forwards and backwards a lot.
Bottom line: this book is not thrilling, but what you don’t know, can kill you.

Successful Aging – by Dr. Daniel Levitin
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 all know about age-related cognitive decline. What if there’s a flipside, though?
Neuroscientist Dr. Daniel Levitin explores the changes that the brain undergoes with age, and notes that it’s not all downhill.
From cumulative improvements in the hippocampi to a dialling-down of the (often overfunctioning) amygdalae, there are benefits too.
The book examines the things that shape our brains from childhood into our eighties and beyond. Many milestones may be behind us, but neuroplasticity means there’s always time for rewiring. Yes, it also covers the “how”.
We learn also about the neurogenesis promoted by such simple acts as taking a different route and/or going somewhere new, and what other things improve the brain’s healthspan.
The writing style is very accessible “pop-science”, and is focused on being of practical use to the reader.
Bottom line: if you want to get the most out of your aging wizening brain, this book is a great how-to manual.
