“Fart walks” have become a cultural phenomenon, after a woman named Mairlyn Smith posted online a now-viral video about how she and her husband go on walks about 60 minutes after dinner and release their gas.
Smith, known on TikTok as @mairlynthequeenoffibre and @mairlynsmith on Instagram, has since appeared on myriad TV and press interviews extolling the benefits of a fart walk. Countless TikTok and Instagram users and have now shared their own experiences of feeling better after taking up the #fartwalk habit.
So what’s the evidence behind the fart walk? And what’s the best way to do it?
Exercise can help get the gas out
We know exercise can help relieve bloating by getting gas moving and out of our bodies.
Researchers from Barcelona, Spain in 2006 asked eight patients complaining of bloating, seven of whom had irritable bowel syndrome, to avoid “gassy” foods such as beans for two days and to fast for eight hours before their study.
Each patient was asked to sit in an armchair, in order to avoid any effects of body position on the movement of gas. Gas was pumped directly into their small bowel via a thin plastic tube that went down their mouth, and the gas expelled from the body was collected into a bag via a tube placed in the rectum. This way, the researchers could determine how much gas was retained in the gut.
The patients were then asked to pedal on a modified exercise bike while remaining seated in their armchairs.
The researchers found that much less gas was retained in the patients’ gut when they exercised. They determined exercise probably helped the movement and release of intestinal gas.
Walking may have another bonus; it may trigger a nerve reflex that helps propel foods and gas contents through the gut.
Walking can also increase internal abdominal pressure as you use your abdominal muscles to stay upright and balance as you walk. This pressure on the colon helps to push intestinal gas out.
Proper fart walk technique
One study from Iran studied the effects of walking in 94 individuals with bloating.
They asked participants to carry out ten to 15 minutes of slow walking (about 1,000 steps) after eating lunch and dinner. They filled out gut symptom questionnaires before starting the program and again at the end of the four week program.
The researchers found walking after meals resulted in improvements to gut symptoms such as belching, farting, bloating and abdominal discomfort.
Now for the crucial part: in the Iranian study, there was a particular way in which participants were advised to walk. They were asked to clasp hands together behind their back and to flex their neck forward.
The clasped hands posture leads to more internal abdominal pressure and therefore more gentle squeezing out of gas from the colon. The flexed neck posture decreases the swallowing of air during walking.
This therefore is the proper fart walk technique, based on science.
What about constipation?
A fart walk can help with constipation.
One study involved middle aged inactive patients with chronic constipation, who did a 12 week program of brisk walking at least 30 minutes a day – combined with 11 minutes of strength and flexibility exercises.
This program, the researchers found, improved constipation symptoms through reduced straining, less hard stools and more complete evacuation.
It also appears that the more you walk the better the benefits for gut symptoms.
In patients with irritable bowel syndrome, one study increasing the daily step count to 9,500 steps from 4,000 steps led to a 50% reduction in the severity of their symptoms.
And just 30 minutes of a fart walk has been shown to improve blood sugar levels after eating.
What if I can’t get outside the house?
If getting outside the house after dinner is impossible, could you try walking slowly on a treadmill or around the house for 1,000 steps?
If not, perhaps you could borrow an idea from the Barcelona research: sit back in an armchair and pedal using a modified exercise bike. Any type of exercise is better than none.
Whatever you do, don’t be a couch potato! Research has found more leisure screen time is linked to a greater risk of developing gut diseases.
We also know physical inactivity during leisure time and eating irregular meals are linked to a higher risk of abdominal pain, bloating and altered bowel motions.
Try the fart walk today
It may not be for everyone but this simple physical activity does have good evidence behind it. A fart walk can improve common symptoms such as bloating, abdominal discomfort and constipation.
It can even help lower blood sugar levels after eating.
Will you be trying a fart walk today?

The Best Kind Of Fiber For Overall Health?

The Fiber Of Good Health
We’ve written before about how most people in industrialized nations in general, and N. America in particular, do not get nearly enough fiber:
Why You’re Probably Not Getting Enough Fiber (And How To Fix It)
Fiber’s important for many aspects of health, not least of all the heart:
What Matters Most For Your Heart? Eat More (Of This) For Lower Blood Pressure
As well, of course, as being critical for gut health:
Gut Health 101: Making Friends With Your Gut (You Can Thank Us Later)
But is all fiber “prebiotic fiber”, and/or are some better than others?
Beta-glucan
A recent study (it’s a mouse study, but promising in its applicability for humans) examined the health impacts of 5 different fiber types:
- pectin
- β-glucan
- wheat dextrin
- resistant starch
- cellulose (control)
As for health metrics, they measured:
- body weight
- adiposity
- indirect calorimetry
- glucose tolerance
- gut microbiota
- metabolites thereof
What they found was…
❝Only β-glucan supplementation during HFD-feeding decreased adiposity and body weight gain and improved glucose tolerance compared with HFD-cellulose, whereas all other fibers had no effect. This was associated with increased energy expenditure and locomotor activity in mice compared with HFD-cellulose.
All fibers supplemented into an HFD uniquely shifted the intestinal microbiota and cecal short-chain fatty acids; however, only β-glucan supplementation increased cecal butyrate concentrations. Lastly, all fibers altered the small-intestinal microbiota and portal bile acid composition. ❞
If you’d like to read more, the study itself is here:
If you’d like to read less, the short version is that they are all good but β-glucan scored best in several metrics.
It also acts indirectly as a GLP-1 agonist, by the way:
The right fiber may help you lose weight
You may be wondering: what is β-glucan found in?
It’s found in many (non-animal product) foods, but oats, barley, mushrooms, and yeasts are all good sources.
Is it available as a supplement?
More or less; there are supplements that contain it generously, here’s an example product on Amazon, a cordyceps extract, of which >30% is β-glucan.
As an aside, cordyceps itself has many other healthful properties too:
Cordyceps: Friend Or Foe? ← the answer is, it depends! If you’re human, it’s a friend.

Cranberry juice really can help with UTIs – and reduce reliance on antibiotics
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.
Cranberry juice has been used medicinally for centuries. Our new research indicates it should be a normal aspect of urinary tract infection (UTI) management today.
While some benefits of cranberry compounds for the prevention of UTIs have been suspected for some time, it hasn’t been clear whether the benefits from cranberry juice were simply from drinking more fluid, or something in the fruit itself.
For our study, published this week, we combined and collectively assessed 3,091 participants across more than 20 clinical trials.
Our analysis indicates that increasing liquids reduces the rate of UTIs compared with no treatment, but cranberry in liquid form is even better at reducing UTIs and antibiotic use.
Julie Falk/Flickr, CC BY-NC-ND Are UTIs really that bad?
Urinary tract infections affect more than 50% of women and 20% of men in their lifetime.
Most commonly, UTIs are caused from the bug called Escherichia coli (E.coli). This bug lives harmlessly in our intestines, but can cause infection in the urinary tract. This is why, particularly for women, it is recommended people wipe from front to back after using the toilet.
An untreated UTI can move up to the kidneys and cause even more serious illness.
Even when not managing infection, many people are anxious about contracting a UTI. Sexually active women, pregnant women and older women may all be at increased risk.
Why cranberries?
To cause a UTI, the bacteria need to attach to the wall of the urinary bladder. Increasing fluids helps to flush out bacteria before it attaches (or makes its way up into the bladder).
Some beneficial compounds in cranberry, such as proanthocyanidins (also called condensed tannins), prevent the bacteria from attaching to the wall itself.
While there are treatments, over 90% of the bugs that cause UTIs exhibit some form of microbial resistance. This suggests that they are rapidly changing and some cases of UTI might be left untreatable.
The juice of cranberries has long been thought to have infection-fighting properties. duckeesue/Shutterstock What we found
Our analysis showed a 54% lower rate of UTIs from cranberry juice consumption compared to no treatment. This means that significantly fewer participants who regularly consumed cranberry juice (most commonly around 200 millilitres each day) reported having a UTI during the periods assessed in the studies we analysed.
Cranberry juice was also linked to a 49% lower rate of antibiotic use than placebo liquid and a 59% lower rate than no treatment, based on analysis of indirect and direct effects across six studies. The use of cranberry compounds, whether in drinks or tablet form, also reduced the prevalence of symptoms associated with UTIs.
While some studies we included presented conflicts of interest (such as receiving funding from cranberry companies), we took this “high risk of bias” into account when analysing the data.
The study found extra hydration helped but not to the same extent as cranberry juice. Pixelshot/Shutterstock So, when can cranberry juice help?
We found three main benefits of cranberry juice for UTIs.
1. Reduced rates of infections
Increasing fluids (for example, drinking more water) reduced the prevalence of UTIs, and taking cranberry compounds (such as tablets) was also beneficial. But the most benefits were identified from increasing fluids and taking cranberry compounds at the same time, such as with cranberry juice.
2. Reduced use of antibiotics
The data shows cranberry juice lowers the need to use antibiotics by 59%. This was identified as fewer participants in randomised cranberry juice groups required antibiotics.
Increasing fluid intake also helped reduce antibiotic use (by 25%). But this was not as useful as increasing fluids at the same time as using cranberry compounds.
Cranberry compounds alone (such as tablets without associated increases in fluid intake) did not affect antibiotic use.
3. Reducing symptoms
Taking cranberry compounds (in any form, liquid or tablet) reduced the symptoms of UTIs, as measured in the overall data, by more than five times.
Take home advice
While cranberry juice cannot treat a UTI, it can certainly be part of UTI management.
If you suspect that you have a UTI, see your GP as soon as possible.

Which Osteoporosis Medication, If Any, Is Right For You?
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.
Which Osteoporosis Medication, If Any, Is Right For You?
We’ve written about osteoporosis before, so here’s a quick recap first in case you missed these:
- The Bare-bones Truth About Osteoporosis
- Exercises To Do (And Exercises To Avoid) If You Have Osteoporosis
- We Are Such Stuff As Fish Are Made Of
- Vit D + Calcium: Too Much Of A Good Thing?
All of those look and diet and/or exercise, with “diet” including supplementation. But what of medications?
So many choices (not all of them right for everyone)
The UK’s Royal Osteoporosis Society says of the very many osteoporosis meds available:
❝In terms of effectiveness, they all reduce your risk of broken bones by roughly the same amount.
Which treatment is right for you will depend on a number of things.❞
…before then going on to list a pageful of things it will depend on, and giving no specific information about what prescriptions or proscriptions may be made based on those factors.
Source: Royal Osteoporosis Society | Which medication should I take?
We’ll try to do better than that here, though we have less space. So let’s get down to it…
First line drug offerings
After diet/supplementation and (if applicable) hormones, the first line of actual drug offerings are generally biphosphates.
Biphosphates work by slowing down your osteoclasts—the cells that break down your bones. They may sound like terrible things to have in the body at all, but remember, your body is always rebuilding itself and destruction is a necessary act to facilitate creation. However, sometimes things can get out of balance, and biphosphates help tip things back into balance.
Common biphosphates include Alendronate/Fosamax, Risedronate/Actonel, Ibandronate/Boniva, and Zolendronic acid/Reclast.
A common downside is that they aren’t absorbed well by the stomach (despite being mostly oral administration, though IV versions exist too) and can cause heartburn / general stomach upset.
An uncommon downside is that messing with the body’s ability to break down bones can cause bones to be rebuilt-in-place slightly incorrectly, which can—paradoxically—cause fractures. But that’s rare and is more common if the drugs are taken in much higher doses (as for bone cancer rather than osteoporosis).
Bone-builders
If you already have low bone density (so you’re fighting to rebuild your bones, not just slow deterioration), then you may need more of a boost.
Bone-building medications include Teriparatide/Forteo, Abaloparatide/Tymlos, and Romosozumab/Evenity.
These are usually given by injection, usually for a course of one or two years.
Once the bone has been built up, it’ll probably be recommended that you switch to a biphosphate or other bone-stabilizing medication.
Estrogen-like effects, without estrogen
If your osteoporosis (or osteoporosis risk) comes from being post-menopausal, estrogen is a very common (and effective!) prescription. However, some people may wish to avoid it, if for example you have a heightened breast cancer risk, which estrogen can exacerbate.
So, medications that have estrogen-like effects post-menopause, but without actually increasing estrogen levels, include: Raloxifene/Evista, and also all the meds we mentioned in the bone-building category above.
Raloxifene/Evista specifically mimics the action of estrogen on bones, while at the same time blocking the effect of estrogen on other tissues.

Tiramisu Crunch Bites
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.
It’s coffee, it’s creamy, it’s nutty, it’s chocolatey, what’s not to love? It has all the well-loved flavors of tiramisu, but this recipe is a simple one, and it’s essentially stuffed dates in a way you’ve never had them before. They’re delectable, decadent, and decidedly good for your health. These things are little nutrient-bombs that’ll keep you reaching for more.
You will need
- Coffee (we will discuss this)
- 150g (5.5oz) mascarpone (if vegan or lactose-intolerant, can be substituted with vegan varieties, or at a pinch, pressed silken tofu)
- 500g (1lb) dates (Medjool are ideal)
- Twice as many almonds as you have dates
- 50g (2oz) dark chocolate (the darkest, bitterest, you can find)
- Edible flower petals if you can source them (some shops sell dried rose petals for this purpose)
Method
(we suggest you read everything at least once before doing anything)
1) Take the mascarpone and whisk (or blend) it with the coffee. What kind of coffee, you ask? Many will use instant coffee (1tbsp granules mixed with enough boiling water to dissolve it), and that is actually healthiest (counterintuitive but true) but if you care for flavor over health, and have the means to make espresso, make it ristretto (so, stop it halfway through filling up an espresso cup), let it cool, and use that. Absolute bonus for flavor (not for health): if you have the means to make Turkish coffee, use an equivalent amount of that (again, cooled).
You will now have coffee-flavoured mascarpone. It’s great for your gut and full of antioxidant polyphenols. Set it aside for the moment.
2) Take the dark chocolate and melt it. Please don’t microwave it or try to do it in a pan directly over the hob; instead, you will need to use a Bain-Marie. If you don’t have one made-for-purpose, you can place a metal or heatproof glass bowl in a saucepan, with something to stop it from touching the floor of the pan. Then boil water in the pan (without letting the water get into the bowl), and melt the chocolate in the bowl—this will allow you to melt it evenly without burning the chocolate.
You will now have melted dark chocolate. It has its own set of polyphenols, and is great for everything from the brain to the gut microbiome.
3) Cut the dates lengthways on one side and remove the stone. Stuff them carefully with the coffee-flavored mascarpone (you can use a teaspoon, or use a piping kit if you have one). Add a couple of almonds to each one. Place them all on a big plate, and drizzle the melted chocolate over them. Add the petals if you have them.
The dates and almonds deliver extra vitamins and minerals in abundance (not to mention, lots of fiber), and also are an amazing combination even just by themselves. With the mascarpone and chocolate added, this winning on new levels. We’re not done yet, though…
4) Chill them in the fridge for about 30 minutes.
Serve!

Pinto Beans vs Fava Beans – 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 pinto beans to fava beans, we picked the pinto beans.
Why?
It wasn’t close!
In terms of macros, pinto beans have more protein and carbs, and much more fiber, resulting in a much lower glycemic index. We mention this, because while often the GI of two similar foods is similar, in this case pinto beans have a GI of 39 (low), while fava beans have a GI of 79 (high). In other words, not at all close, and pinto beans are the clear winner.
When it comes to vitamins, pinto beans have more of vitamins B1, B5, B6, B7, B9, C, E, K, and choline, while fava beans have more of vitamins B2 and B3. Once again, not close, and that’s before we take into account the margins of difference for those vitamins; the margins of difference are much greater on the pinto beans’ side of the scale, for example pinto beans having 47x more vitamin E, while fava beans have only 43% more vitamin B2. So, orders of magnitude less. A clear win for pinto beans in all respects.
In the category of minerals, pinto beans have more calcium, iron, magnesium, manganese, phosphorus, potassium, and selenium, while fava beans have more copper and zinc. This time, the margins of difference were quite moderate across the board, and/but pinto beans win on clear strength of numbers.
All in all, three clear wins for pinto beans add up to one big clear win for pinto beans.
Enjoy!

Edamame vs Soybeans – 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 edamame to soybeans, we picked the soybeans.
Why?
You may be thinking: aren’t edamame soybeans? And yes, yes they are. But just like our many instances of pitting Brassica oleracea vs Brassica oleracea (one species, many cultivars e.g. broccoli, cauliflower, kale, cabbage, Brussels sprouts, etc), there are still differences. In this case, edamame and soybeans aren’t even different cultivars, what are conventionally called edamame are just the young beans of the plant, while what are conventionally called soybeans are the mature beans of the plant.
The main nutritional difference is: as they get older, they lose vitamins and gain minerals. More on that later. But first, “main difference” isn’t “only difference”, so…
In terms of macros, edamame have more carbs, while soybeans have a little more fiber and a lot more protein. An easy win for the mature soybeans.
In the category of vitamins, edamame have more of vitamins A, B1, B3, B5, B9, C, E, K, and choline, while soybeans have more of vitamins B2 and B6. A clear win for edamame, this time.
When it comes to minerals, the nutritional tables are turned, and edamame have more manganese and zinc, while soybeans have more calcium, copper, iron, magnesium, phosphorus, potassium, and selenium. An easy win for soybeans.
Adding up the sections makes for a two-to-one victory for soybeans, but by all means enjoy either or both; diversity is good!
