Guinness Is Good For You*
*This is our myth-buster edition, so maybe best not take that at face value!
To this day, writing the words “Guinness is” into Google will autocomplete to “Guinness is good for you”. The ad campaign proclaiming such launched about a hundred years ago, and was based on Guinness as it was when it was launched another hundred years before that.
Needless to say, none of this was based on modern science.
Is there any grain of truth?
Perhaps its strongest health claim, in terms of what stands up to modern scrutiny, is that it does contain some B vitamins. Famously (as it was once given to pregnant women in Ireland on the strength of such) it contains folate (also known as Vitamin B9). How much?
A 15oz glass of Guinness contains 12.8µg of folate, which is 3.2% of the RDA. In other words, you could get all the folate your body needs by drinking just 32 glasses of Guinness per day.
With that in mind, you might want to get the non-alcoholic version!
“I heard you could live on just Guinness and oranges, because it contains everything but vitamin C?”
The real question is: how long could you live? Otherwise, a facetious answer here could be akin to the “fun fact” that you can drink lava… once.
Guinness is missing many essential amino acids and fatty acids, several vitamins, and many minerals. Exactly what it’s missing may vary slightly from region to region, as while the broad recipe is the same, some processes add or remove some extra micronutrients.
As to what you’d die of first, for obvious reasons there have been no studies done on this, but our money would be on liver failure.
It would also wreak absolute havoc with your kidneys, but kidneys are tricky beasts—you can be down to 10% functionality and unaware that anything’s wrong yet. So we think liver failure would get you first.
(Need that 0.0% alcohol Guinness link again? Here it is)
Fun fact: Top contender in the category of “whole food” is actually seaweed (make sure you don’t get too much iodine, though)!
Or, should we say, top natural contender. Because foods that have been designed by humans to contain everything we need and more for optimized health, such as Huel, do exactly what they say on the tin.
And in case you’re curious…

SuperLife – by Darin Olien
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 mostly know more or less what we’re supposed to be doing, at least to a basic level, when it comes to diet and exercise. So why don’t we do it?
Where Darin Olien excels in this one is making healthy living—mostly the dietary aspects thereof—not just simple, but also easy.
He gives principles we can apply rather than having to memorize lots of information… And his “this will generally be better than that” format also means that the feeling is one of reducing harm, increasing benefits, without needing to get absolutist about anything. And that, too, makes healthy living easier.
The book also covers some areas that a lot of books of this genre don’t—such as blood oxygenation, and maintenance of healthy pH levels—and aspects such as those are elements that help this book to stand out too.
Don’t be put off and think this is a dry science textbook, though—it’s not. In fact, the tone is light and the style is easy-reading throughout.
Bottom line: if you want to take an easy, casual, but scientifically robust approach to tweaking your health for the better, this book will enable you to do that.

Fast Like A Girl – by Dr. Mindy Pelz
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.
A lot of information out there when it comes to intermittent fasting is very much centered on men in the 25–35 years age range. What about the rest of us?
Our physiological needs are not the same, and it’d be foolhardy to ignore that. But what things do still stand the same, and what things would benefit from a different approach in our cases?
Dr. Pelz has our back with this book packed with information based on the best science currently out there. She gives a general overview of fasting with full consideration to the fact that we the reader may well be female or over a certain age or both. In addition, the book offers:
- Metabolic switching (the “missing key to weight loss”)
- Building a fasting lifestyle (that works with your actual life, not just on paper)
- How to time fasting according to your menstrual cycle (if you don’t have a cycle, she has you covered too)
- How to break a fast—properly (and many other hacks/tips/tricks to make fasting so much easier)
Bottom line: if you want to do intermittent fasting and want to work with rather than against your body, then this book is a fine option.

How a Friend’s Death Turned Colorado Teens Into Anti-Overdose Activists
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.
Gavinn McKinney loved Nike shoes, fireworks, and sushi. He was studying Potawatomi, one of the languages of his Native American heritage. He loved holding his niece and smelling her baby smell. On his 15th birthday, the Durango, Colorado, teen spent a cold December afternoon chopping wood to help neighbors who couldn’t afford to heat their homes.
McKinney almost made it to his 16th birthday. He died of fentanyl poisoning at a friend’s house in December 2021. His friends say it was the first time he tried hard drugs. The memorial service was so packed people had to stand outside the funeral home.
Now, his peers are trying to cement their friend’s legacy in state law. They recently testified to state lawmakers in support of a bill they helped write to ensure students can carry naloxone with them at all times without fear of discipline or confiscation. School districts tend to have strict medication policies. Without special permission, Colorado students can’t even carry their own emergency medications, such as an inhaler, and they are not allowed to share them with others.
“We realized we could actually make a change if we put our hearts to it,” said Niko Peterson, a senior at Animas High School in Durango and one of McKinney’s friends who helped write the bill. “Being proactive versus being reactive is going to be the best possible solution.”
Individual school districts or counties in California, Maryland, and elsewhere have rules expressly allowing high school students to carry naloxone. But Jon Woodruff, managing attorney at the Legislative Analysis and Public Policy Association, said he wasn’t aware of any statewide law such as the one Colorado is considering. Woodruff’s Washington, D.C.-based organization researches and drafts legislation on substance use.
Naloxone is an opioid antagonist that can halt an overdose. Available over the counter as a nasal spray, it is considered the fire extinguisher of the opioid epidemic, for use in an emergency, but just one tool in a prevention strategy. (People often refer to it as “Narcan,” one of the more recognizable brand names, similar to how tissues, regardless of brand, are often called “Kleenex.”)
The Biden administration last year backed an ad campaign encouraging young people to carry the emergency medication.
Most states’ naloxone access laws protect do-gooders, including youth, from liability if they accidentally harm someone while administering naloxone. But without school policies explicitly allowing it, the students’ ability to bring naloxone to class falls into a gray area.
Ryan Christoff said that in September 2022 fellow staff at Centaurus High School in Lafayette, Colorado, where he worked and which one of his daughters attended at the time, confiscated naloxone from one of her classmates.
“She didn’t have anything on her other than the Narcan, and they took it away from her,” said Christoff, who had provided the confiscated Narcan to that student and many others after his daughter nearly died from fentanyl poisoning. “We should want every student to carry it.”
Boulder Valley School District spokesperson Randy Barber said the incident “was a one-off and we’ve done some work since to make sure nurses are aware.” The district now encourages everyone to consider carrying naloxone, he said.
Community’s Devastation Turns to Action
In Durango, McKinney’s death hit the community hard. McKinney’s friends and family said he didn’t do hard drugs. The substance he was hooked on was Tapatío hot sauce — he even brought some in his pocket to a Rockies game.
After McKinney died, people started getting tattoos of the phrase he was known for, which was emblazoned on his favorite sweatshirt: “Love is the cure.” Even a few of his teachers got them. But it was classmates, along with their friends at another high school in town, who turned his loss into a political movement.
“We’re making things happen on behalf of him,” Peterson said.
The mortality rate has spiked in recent years, with more than 1,500 other children and teens in the U.S. dying of fentanyl poisoning the same year as McKinney. Most youth who die of overdoses have no known history of taking opioids, and many of them likely thought they were taking prescription opioids like OxyContin or Percocet — not the fake prescription pills that increasingly carry a lethal dose of fentanyl.
“Most likely the largest group of teens that are dying are really teens that are experimenting, as opposed to teens that have a long-standing opioid use disorder,” said Joseph Friedman, a substance use researcher at UCLA who would like to see schools provide accurate drug education about counterfeit pills, such as with Stanford’s Safety First curriculum.
Allowing students to carry a low-risk, lifesaving drug with them is in many ways the minimum schools can do, he said.
“I would argue that what the schools should be doing is identifying high-risk teens and giving them the Narcan to take home with them and teaching them why it matters,” Friedman said.
Writing in The New England Journal of Medicine, Friedman identified Colorado as a hot spot for high school-aged adolescent overdose deaths, with a mortality rate more than double that of the nation from 2020 to 2022.
“Increasingly, fentanyl is being sold in pill form, and it’s happening to the largest degree in the West,” said Friedman. “I think that the teen overdose crisis is a direct result of that.”
If Colorado lawmakers approve the bill, “I think that’s a really important step,” said Ju Nyeong Park, an assistant professor of medicine at Brown University, who leads a research group focused on how to prevent overdoses. “I hope that the Colorado Legislature does and that other states follow as well.”
Park said comprehensive programs to test drugs for dangerous contaminants, better access to evidence-based treatment for adolescents who develop a substance use disorder, and promotion of harm reduction tools are also important. “For example, there is a national hotline called Never Use Alone that anyone can call anonymously to be supervised remotely in case of an emergency,” she said.
Taking Matters Into Their Own Hands
Many Colorado school districts are training staff how to administer naloxone and are stocking it on school grounds through a program that allows them to acquire it from the state at little to no cost. But it was clear to Peterson and other area high schoolers that having naloxone at school isn’t enough, especially in rural places.
“The teachers who are trained to use Narcan will not be at the parties where the students will be using the drugs,” he said.
And it isn’t enough to expect teens to keep it at home.
“It’s not going to be helpful if it’s in somebody’s house 20 minutes outside of town. It’s going to be helpful if it’s in their backpack always,” said Zoe Ramsey, another of McKinney’s friends and a senior at Animas High School.
“We were informed it was against the rules to carry naloxone, and especially to distribute it,” said Ilias “Leo” Stritikus, who graduated from Durango High School last year.
But students in the area, and their school administrators, were uncertain: Could students get in trouble for carrying the opioid antagonist in their backpacks, or if they distributed it to friends? And could a school or district be held liable if something went wrong?
He, along with Ramsey and Peterson, helped form the group Students Against Overdose. Together, they convinced Animas, which is a charter school, and the surrounding school district, to change policies. Now, with parental permission, and after going through training on how to administer it, students may carry naloxone on school grounds.
Durango School District 9-R spokesperson Karla Sluis said at least 45 students have completed the training.
School districts in other parts of the nation have also determined it’s important to clarify students’ ability to carry naloxone.
“We want to be a part of saving lives,” said Smita Malhotra, chief medical director for Los Angeles Unified School District in California.
Los Angeles County had one of the nation’s highest adolescent overdose death tallies of any U.S. county: From 2020 to 2022, 111 teens ages 14 to 18 died. One of them was a 15-year-old who died in a school bathroom of fentanyl poisoning. Malhotra’s district has since updated its policy on naloxone to permit students to carry and administer it.
“All students can carry naloxone in our school campuses without facing any discipline,” Malhotra said. She said the district is also doubling down on peer support and hosting educational sessions for families and students.
Montgomery County Public Schools in Maryland took a similar approach. School staff had to administer naloxone 18 times over the course of a school year, and five students died over the course of about one semester.
When the district held community forums on the issue, Patricia Kapunan, the district’s medical officer, said, “Students were very vocal about wanting access to naloxone. A student is very unlikely to carry something in their backpack which they think they might get in trouble for.”
So it, too, clarified its policy. While that was underway, local news reported that high school students found a teen passed out, with purple lips, in the bathroom of a McDonald’s down the street from their school, and used Narcan to revive them. It was during lunch on a school day.
“We can’t Narcan our way out of the opioid use crisis,” said Kapunan. “But it was critical to do it first. Just like knowing 911.”
Now, with the support of the district and county health department, students are training other students how to administer naloxone. Jackson Taylor, one of the student trainers, estimated they trained about 200 students over the course of three hours on a recent Saturday.
“It felt amazing, this footstep toward fixing the issue,” Taylor said.
Each trainee left with two doses of naloxone.

Why Zebras Don’t Get Ulcers – by Dr. Robert M. Sapolsky

The book does kick off with a section that didn’t age well—he talks of the stress induced globally by the Spanish Flu pandemic of 1918, and how that kind of thing just doesn’t happen any more. Today, we have much less existentially dangerous stressors!
However, the fact we went and had another pandemic really only adds weight to the general arguments of the book, rather than detracting.
We are consistently beset by “the slings and arrows of outrageous fortune” as Shakespeare would put it, and there’s a reason (or twenty) why many people go grocery-shopping with the cortisol levels of someone being hunted for sport.
So, why don’t zebras get ulcers, as they actually are hunted for food?
They don’t have rent to pay or a mortgage, they don’t have taxes, or traffic, or a broken washing machine, or a project due in the morning. Their problems come one at a time. They have a useful stress response to a stressful situation (say, being chased by lions), and when the danger is over, they go back to grazing. They have time to recover.
For us, we are (usually) not being chased by lions. But we have everything else, constantly, around the clock. So, how to fix that?
Dr. Sapolsky comprehensively describes our physiological responses to stress in quite different terms than many. By reframing stress responses as part of the homeostatic system—trying to get the body back into balance—we find a solution, or rather: ways to help our bodies recover.
The style is “pop-science” and is very accessible for the lay reader while still clearly coming from a top-level academic who is neck-deep in neuroendocrinological research. Best of both worlds!
Bottom line: if you try to take very day at a time, but sometimes several days gang up on you at once, and you’d like to learn more about what happens inside you as a result and how to fix that, this book is for you!

How To Set Anxiety Aside

How To Set Anxiety Aside
We’ve talked previously about how to use the “release” method to stop your racing mind.
That’s a powerful technique, but sometimes we need to be calm enough to use it. So first…
Breathe
Obviously. But, don’t underestimate the immediate power of focusing on your breath, even just for a moment.
There are many popular breathing exercises, but here’s one of the simplest and most effective, “4–4 breathing”:
- Breathe in for a count of four
- Hold for a count four
- Breathe out for a count of four
- Hold for a count of four
- Repeat
Depending on your lung capacity and what you’re used to, it may be that you need to count more quickly or slowly to make it feel right. Experiment with what feels comfortable for you, but the general goal should breathing deeply and slowly.
Identify the thing that’s causing you anxiety
We’ve also talked previously about how to use the RAIN technique to manage difficult emotions, and that’s good for handling anxiety too.
Another powerful tool is journaling.
Read: How To Use Journaling to Challenge Anxious Thoughts
If you don’t want to use any of those (very effective!) methods, that’s fine too—journaling isn’t for everyone.
You can leverage some of the same benefits by simply voicing your worries, even to yourself:
There’s an old folk tradition of “worry dolls”; these are tiny little dolls so small they can be kept in a pocket-size drawstring purse. Last thing at night, the user whispers their worries to the dolls and puts them back in their bag, where they will work on the person’s problem overnight.
We’re a health and productivity newsletter, not a dealer of magic and spells, but you can see how it works, right? It gets the worries out of one’s head, and brings about a helpful placebo effect too.
Focus on what you can control
- Most of what you worry about will not happen.
- Some of what you worry about may happen.
- Worrying about it will not help.
In fact, in some cases it may bring about what you fear, by means of the nocebo effect (like the placebo effect, but bad). Additionally, worrying drains your body and makes you less able to deal with whatever life does throw at you.
So while “don’t worry; be happy” may seem a flippant attitude, sometimes it can be best. However, don’t forget the other important part, which is actually focusing on what you can control.
- You can’t control whether your car will need expensive maintenance…
- …but you can control whether you budget for it.
- You can’t control whether your social event will go well or ill…
- …but you can control how you carry yourself.
- You can’t control whether your loved one’s health will get better or worse…
- …but you can control how you’re there for them, and you can help them take what sensible precautions they may.
…and so forth.
Look after your body as well!
Your body and mind are deeply reliant on each other. In this case, just as anxiety can drain your body’s resources, keeping your body well-nourished, well-exercised, and well-rested and can help fortify you against anxiety. For example, when it comes to diet, exercise, and sleep:
- Read: Fruit and vegetable intake is inversely associated with perceived stress across the adult lifespan
- Read: Exercise and anxiety: physical activity appears to be protective against anxiety disorders in clinical and non-clinical populations
- Read: Sleep problems predict and are predicted by generalized anxiety/depression
Don’t know where to start? How about the scientifically well-researched, evidence-based, 7-minute workout?

Cupping: How It Works (And How It Doesn’t)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Good Health By The Cup?
In Tuesday’s newsletter, we asked you for your opinion of cupping (the medical practice), and got the above-depicted, below-described, set of responses:
- About 40% said “It may help by improving circulation and stimulating the immune system”
- About 26% said “I have never heard of the medical practice of cupping before this”
- About 19% said “It is pseudoscience and/or placebo at best, but probably not harmful
- About 9% said “It is a good, evidence-based practice that removes toxins and stimulates health”
- About 6% said “It is a dangerous practice that often causes harm to people who need medical help”
So what does the science say?
First, a quick note for those unfamiliar with cupping: it is the practice of placing a warmed cup on the skin (open side of the cup against the skin). As the warm air inside cools, it reduces the interior air pressure, which means the cup is now (quite literally) a suction cup. This pulls the skin up into the cup a little. The end result is visually, and physiologically, the same process as what happens if someone places the nozzle of a vacuum cleaner against their skin. For that matter, there are alternative versions that simply use a pump-based suction system, instead of heated cups—but the heated cups are most traditional and seem to be most popular. See also:
National Center for Complementary and Integrative Health | Cupping
It is a dangerous practice that often causes harm to people who need medical help: True or False?
False, for any practical purposes.
- Directly, it can (and usually does) cause minor superficial harm, much like many medical treatments, wherein the benefits are considered to outweigh the harm, justifying the treatment. In the case of cupping, the minor harm is usually a little bruising, but there are other risks; see the link we gave just above.
- Indirectly, it could cause harm by emboldening a person to neglect a more impactful treatment for their ailment.
But, there’s nothing for cupping akin to the “the most common cause of death is when someone gets a vertebral artery fatally severed” of chiropractic, for example.
It is a good, evidence-based practice that removes toxins and stimulates health: True or False?
True and False in different parts. This one’s on us; we included four claims in one short line. But let’s look at them individually:
- Is it good? Well, those who like it, like it. It legitimately has some mild health benefits, and its potential for harm is quite small. We’d call this a modest good, but good nonetheless.
- Is it evidence-based? Somewhat, albeit weakly; there are some papers supporting its modest health claims, although the research is mostly only published in journals of alternative medicine, and any we found were in journals that have been described by scientists as pseudoscientific.
- Does it remove toxins? Not directly, at least. There is also a version that involves making a small hole in the skin before applying the cup, the better to draw out the toxins (called “wet cupping”). This might seem a little medieval, but this is because it is from early medieval times (wet cupping’s first recorded use being in the early 7th century). However, the body’s response to being poked, pierced, sucked, etc is to produce antibodies, and they will do their best to remove toxins. So, indirectly, there’s an argument.
- Does it stimulate health? Yes! We’ll come to that shortly. But first…
It is pseudoscience and/or placebo at best, but probably not harmful: True or False?
True in that its traditionally-proposed mechanism of action is a pseudoscience and placebo almost certainly plays a strong part, and also in that it’s generally not harmful.
On it being a pseudoscience: we’ve talked about this before, but it bears repeating; just because something’s proposed mechanism of action is pseudoscience, doesn’t necessarily mean it doesn’t work by some other mechanism of action. If you tell a small child that “eating the rainbow” will improve their health, and they believe this is some sort of magical rainbow power imbuing them with health, then the mechanism of action that they believe in is a pseudoscience, but eating a variety of colorful fruit and vegetables will still be healthy.
In the case of cupping, its proposed mechanism of action has to do withbalancing qi, yin and yang, etc (for which scientific evidence does not exist), in combination with acupuncture lore (for which some limited weak scientific evidence exists). On balancing qi, yin and yang etc, this is a lot like Europe’s historically popular humorism, which was based on the idea of balancing the four humors (blood, yellow bile, black bile, phlegm). Needless to say, humorism was not only a pseudoscience, but also eventually actively disproved with the advent of germ theory and modern medicine. Cupping therapy is not more scientifically based than humorism.
On the placebo side of things, there probably is a little more to it than that; much like with acupuncture, a lot of it may be a combination of placebo and using counter-irritation, a nerve-tricking method to use pain to reduce pain (much like pressing with one’s nail next to an insect bite).
Here’s one of the few studies we found that’s in what looks, at a glance, to be a reputable journal:
Cupping therapy and chronic back pain: systematic review and meta-analysis
It may help by improving circulation and stimulating the immune system: True or False?
True! It will improve local circulation by forcing blood into the area, and stimulate the immune system by giving it a perceived threat to fight.
Again, this can be achieved by many other means; acupuncture (or just “dry needling”, which is similar but without the traditional lore), a cold shower, and/or exercise (and for that matter, sex—which combines exercise, physiological arousal, and usually also foreign bodies to respond to) are all options that can improve circulation and stimulate the immune system.
You can read more about using some of these sorts of tricks for improving health in very well-evidenced, robustly scientific ways here:
