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:

Against heart disease

The title says it all in this one:

A meta-analysis shows that docosahexaenoic acid from algal oil reduces serum triglycerides and increases HDL-cholesterol and LDL-cholesterol in persons without coronary heart disease

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.

    ❝I may have missed it, but how much black pepper provides benefits?❞

    So, for any new subscribers joining us today, this is about two recent main features:

    As for a daily dosage of black pepper, it varies depending on the benefit you’re looking for, but:

    • 5–20mg of piperine is the dosage range used in most scientific studies we looked at
    • 10mg is a very common dosage found in many popular supplements
    • That’s the mass of piperine though, so if taking it as actual black pepper rather than as an extract, ½ teaspoon is considered sufficient to enjoy benefits.

    ❝I loved the health benefits of pepper. I do not like pepper. Where can I get it as a supplement?❞

    You can simply buy whole black peppercorns and take a few with water as though they were tablets. Your stomach acid will do the rest. Black pepper is also good for digestion, so taking it with a meal is best.

    You can buy piperine (black pepper extract) by itself as a supplement in powder form, but if you don’t like black pepper, you will probably not like this powder either. We couldn’t find it readily in capsule form.

    You can buy piperine (black pepper extract) as an adjunct to other supplements, with perhaps the most common/popular being turmeric capsules that also contain 10mg (or more) piperine per capsule. Shop around if you like, but here’s one that has 15mg piperine* per capsule, for example.

    *They call it “Bioperine®” but that is literally just piperine. Same go

  • 7 Minutes, 30 Days, Honest Review: How Does The 7-Minute Workout Stack Up?

    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.

    For those who don’t like exercising, “the 7-minute workout” (developed by exercise scientists Chris Jordan and Bret Klika) has a lot of allure. After all, it’s just 7 minutes and then you’re done! But how well does it stand up, outside of the lab?

    Down-to-Earth

    Business Insider’s Kelly Reilly is not a health guru, and here he reviews the workout for us, so that we can get a real view of what it’s really like in the real world. What does he want us to know?

    • It’s basically an optimized kind of circuit training, and can be done with no equipment aside from a floor, a wall, and a chair
    • It’s one exercise for 30 seconds, then 10 seconds rest, then onto the next exercise
    • He found it a lot easier to find the motivation to do this, than go to the gym. After all “it’s just 7 minutes” is less offputting than getting in the car, driving someplace, using public facilities, driving back, etc. Instead, it’s just him in the comfort of his home
    • The exercise did make him sweat and felt like a “real” workout in that regard
    • He didn’t like missing out on training his biceps, though, since there are no pulling movements
    • He lost a little weight over the course of the month, though that wasn’t his main goal (and indeed, he was not eating healthily)
    • He did feel better each day after working out, and at the end of the month, he enjoyed feeling self-confident in a tux that now fitted him better than it did before

  • Holding Back The Clock on Aging

    Holding Back The Clock on Aging

    Dr. Eric Verdin specializes in Holding Back The Clock, with a focus on Aging.

    This is Dr. Eric Verdin, President and CEO of the Buck Institute of Research on Aging. He’s also held faculty positions at the University of Brussels, the NIH, and the Picower Institute for Medical Research. Dr. Verdin is also a professor of medicine at University of California, San Francisco.

    Dr. Verdin’s laboratory focuses on the role of epigenetic regulators (especially the behaviors of certain enzymes) in the aging process. He studies how metabolism, diet, and chemical factors regulate the aging process and its associated diseases, including Alzheimer’s.

    He has published more than 210 scientific papers and holds more than 15 patents. He is a highly cited scientist and has been recognized for his research with a Glenn Award for Research in Biological Mechanisms of Aging.

    And that’s just what we could fit here! Basically, he knows his stuff.

    What we can do

    Dr. Verdin’s position is bold, but rooted in evidence:

    ❝Lifestyle is responsible for about 93% of our longevity—only about 7% is genetics. Based on the data, if implementing health lifestyle choices, most people could live to 95 in good health. So there’s 15 to 17 extra years of healthy life that is up for grabs❞

    ~ Dr. Eric Verdin

    See for example:

    How we can do it

    Well, we all know “the big five”:

    • Good diet (Mediterranean Diet as usual is recommended)
    • Good exercise (more on this in a moment)
    • Good sleep (more on this in a moment)
    • Avoid alcohol (not controversial)
    • Don’t smoke (need we say more)

    When it comes to exercise, generally recognized as good is at least 150 minutes per week of moderate intensity exercise (for example, a brisk walk, or doing the gardening), and at least three small sessions a week of high intensity exercise, unless contraindicated by some medical condition.

    As for Dr. Verdin’s take on this…

    What Dr. Verdin recommends is:

    • make it personalized
    • make it pre-emptive
    • make it better

    The perfect exercise plan is only perfect if you actually do it. And if you actually can do it, for that matter.

    Prevention is so much better (and easier) than cure for a whole array of maladies. So while there may be merit in thinking “what needs fixing”, Dr. Verdin encourages us to take extra care to not neglect factors of our health that seem “good enough”. Because, give them time and neglect, and they won’t be!

    Wherever we’re at in life and health, there’s always at least some little way we could make it a bit better. Dr. Verdin advises us to seek out those little improvements, even if it’s just a nudge better here, a nudge better there, all those nudges add up!

    About sleep…

    It’s perhaps the easiest one to neglect (writer’s note: as a writer, I certainly feel that way!), but his biggest take-away tip for this is:

    Worry less about what time you set an alarm for in the morning. Instead, set an alarm for the evening—to remind you when to go to bed.

  • The Philosophy Gym – by Dr. Stephen Law

    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.

    If you’d like to give those “little gray cells” an extra workout, this book is a great starting place.

    Dr. Stephen Law is Director of Philosophy at the Department of Continuing Education, University of Oxford. As such, he’s no stranger to providing education that’s both attainable and yet challenging. Here, he lays out important philosophical questions, and challenges the reader to get to grips with them in a systematic fashion.

    Each of the 25 questions/problems has a chapter devoted to it, and is ranked:

    • Warm-up
    • Moderate
    • More Challenging

    But, he doesn’t leave us to our own devices, nor does he do like a caricature of a philosopher and ask us endless rhetorical questions. Instead, he looks at various approaches taken by other philosophers over time, and invites the reader to try out those methods.

    The real gain of this book is not the mere enjoyment of reading, but rather in taking those thinking skills and applying them in life… because most if not all of them do have real-world applications and/or implications too.

    The book’s strongest point? That it doesn’t assume prior knowledge (and yet also doesn’t patronize the reader). Philosophy can be difficult to dip one’s toes into without a guide, because philosophers writing about philosophy can at first be like finding yourself at a party where you know nobody, but they all know each other.

    In contrast, Law excels at giving quick, to-the-point ground-up summaries of key ideas and their progenitors.

    In short: a wonderful way to get your brain doing things it might not have tried before!

  • Native Americans Have Shorter Life Spans. Better Health Care Isn’t the Only 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.

    HISLE, S.D. — Katherine Goodlow is only 20, but she has experienced enough to know that people around her are dying too young.

    Goodlow, a member of the Lower Brule Sioux Tribe, said she’s lost six friends and acquaintances to suicide, two to car crashes, and one to appendicitis. Four of her relatives died in their 30s or 40s, from causes such as liver failure and covid-19, she said. And she recently lost a 1-year-old nephew.

    “Most Native American kids and young people lose their friends at a young age,” said Goodlow, who is considering becoming a mental health therapist to help her community. “So, I’d say we’re basically used to it, but it hurts worse every time we lose someone.”

    Native Americans tend to die much earlier than white Americans. Their median age at death was 14 years younger, according to an analysis of 2018-21 data from the Centers for Disease Control and Prevention

    The disparity is even greater in Goodlow’s home state. Indigenous South Dakotans who died between 2017 and 2021 had a median age of 58 — 22 years younger than white South Dakotans, according to state data.

    Donald Warne, a physician who is co-director of the Johns Hopkins Center for Indigenous Health and a member of the Oglala Sioux Tribe, can rattle off the most common medical conditions and accidents killing Native Americans.

    But what’s ultimately behind this low life expectancy, agree Warne and many other experts on Indigenous health, are social and economic forces. They argue that in addition to bolstering medical care and fully funding the Indian Health Service — which provides health care to Native Americans — there needs to be a greater investment in case management, parenting classes, and home visits.

    “It’s almost blasphemy for a physician to say,” but “the answer to addressing these things is not hiring more doctors and nurses,” Warne said. “The answer is having more community-based preventions.”

    The Indian Health Service funds several kinds of these programs, including community health worker initiatives, and efforts to increase access to fresh produce and traditional foods.

    Private insurers and state Medicaid programs, including South Dakota’s, are increasingly covering such services. But insurers don’t pay for all the services and aren’t reaching everyone who qualifies, according to Warne and the National Academy for State Health Policy.

    Warne pointed to Family Spirit, a program developed by the Johns Hopkins center to improve health outcomes for Indigenous mothers and children.

    Chelsea Randall, the director of maternal and child health at the Great Plains Tribal Leaders’ Health Board, said community health workers educate Native pregnant women and connect them with resources during home visits.

    “We can be with them throughout their pregnancy and be supportive and be the advocate for them,” said Randall, whose organization runs Family Spirit programs across seven reservations in the Dakotas, and in Rapid City, South Dakota.

    The community health workers help families until children turn 3, teaching parenting skills, family planning, drug abuse prevention, and stress management. They can also integrate the tribe’s culture by, for example, using their language or birthing traditions.

    The health board funds Family Spirit through a grant from the federal Health Resources and Services Administration, Randall said. Community health workers, she said, use some of that money to provide child car seats and to teach parents how to properly install them to counter high rates of fatal crashes.

    Other causes of early Native American deaths include homicide, drug overdoses, and chronic diseases, such as diabetes, Warne said. Native Americans also suffer a disproportionate number of infant and maternal deaths.

    The crisis is evident in the obituaries from the Sioux Funeral Home, which mostly serves Lakota people from the Pine Ridge Reservation and surrounding area. The funeral home’s Facebook page posts obituaries for older adults, but also for many infants, toddlers, teenagers, young adults, and middle-aged residents.

    Misty Merrival, who works at the funeral home, blames poor living conditions. Some community members struggle to find healthy food or afford heat in the winter, she said. They may live in homes with broken windows or that are crowded with extended family members. Some neighborhoods are strewn with trash, including intravenous needles and broken bottles.

    Seeing all these premature deaths has inspired Merrival to keep herself and her teenage daughter healthy by abstaining from drugs and driving safely. They also talk every day about how they’re feeling, as a suicide-prevention strategy.

    “We’ve made a promise to each other that we wouldn’t leave each other like that,” Merrival said.

    Many Native Americans live in small towns or on poor, rural reservations. But rurality alone doesn’t explain the gap in life expectancy. For example, white people in rural Montana live 17 years longer, on average, than Native Americans in the state, according to state data reported by Lee Enterprises newspapers.

    Many Indigenous people also face racism or personal trauma from child or sexual abuse and exposure to drugs or violence, Warne said. Some also deal with generational trauma from government programs and policies that broke up families and tried to suppress Native American culture.

    Even when programs are available, they’re not always accessible.

    Families without strong internet connections can’t easily make video appointments. Some lack cars or gas money to travel to clinics, and public transportation options are limited.

    Randall, the health board official, is pregnant and facing her own transportation struggles.

    It’s a three-hour round trip between her home in the town of Pine Ridge and her prenatal appointments in Rapid City. Randall has had to cancel several appointments when family members couldn’t lend their cars.

    Goodlow, the 20-year-old who has lost several loved ones, lives with seven other people in her mother’s two-bedroom house along a gravel road. Their tiny community on the Pine Ridge Reservation has homes and ranches but no stores.

    Goodlow attended several suicide-prevention presentations in high school. But the programs haven’t stopped the deaths. One friend recently killed herself after enduring the losses of her son, mother, best friend, and a niece and nephew.

    A month later, another friend died from a burst appendix at age 17, Goodlow said. The next day, Goodlow woke up to find one of her grandmother’s parakeets had died. That afternoon, she watched one of her dogs die after having seizures.

    “I thought it was like some sign,” Goodlow said. “I started crying and then I started thinking, ‘Why is this happening to me?’”

    Warne said the overall conditions on some reservations can create despair. But those same reservations, including Pine Ridge, also contain flourishing art scenes and language and cultural revitalization programs. And not all Native American communities are poor.

    Warne said federal, state, and tribal governments need to work together to improve life expectancy. He encourages tribes to negotiate contracts allowing them to manage their own health care facilities with federal dollars because that can open funding streams not available to the Indian Health Service.

    Katrina Fuller is the health director at Siċaŋġu Co, a nonprofit group on the Rosebud Reservation in South Dakota. Fuller, a member of the Rosebud Sioux Tribe, said the organization works toward “wicozani,” or the good way of life, which encompasses the physical, emotional, cultural, and financial health of the community.

    Siċaŋġu Co programs include bison restoration, youth development, a Lakota language immersion school, financial education, and food sovereignty initiatives.

    “Some people out here that are struggling, they have dreams, too. They just need the resources, the training, even the moral support,” Fuller said. “I had one person in our health coaching class tell me they just really needed someone to believe in them, that they could do it.”

  • Egg Whites vs Whole Eggs – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing egg whites to whole eggs, we picked the whole eggs.

    Why?

    Egg whites are mostly protein. Egg yolks are mostly fat, with some protein.

    However, fat ≠ bad, and the yolk is also where the choline is stored, which itself (as well as its benefits for your brain) will tend to reduce fat storage in the body.

    Furthermore, the yolk contains an assortment of vitamins, minerals, and essential amino acids. After all, the yolk is there specifically to contain everything needed to turn a cluster of cells into a small bird.
