Gut Health 101
We have so many microorganisms inside us, that by cell count, their cells outnumber ours more than ten-to-one. By gene count, we have 23,000 and they have more than 3,000,000. In effect, we are more microbe than we are human. And, importantly: they form a critical part of what keeps our overall organism ticking on.
Read all about it: The role of the gut microbiota in nutrition and health
Our trillions of tiny friends keep us alive, so it really really pays to return the favor.
But how?
Probiotics and fermented foods
You probably guessed this one, but it’d be remiss not to mention it first. It’s no surprise that probiotics help; the clue is in the name. In short, they help add diversity to your microbiome (that’s a good thing).
Read from the NIH: Probiotics: What You Need To Know
As for fermented foods, not every fermented food will boost your microbiota, but great options include…
- Fermented vegetables (sauerkraut, pickles, etc)
- You’ll often hear kimchi mentioned; that is also pickled vegetables, usually mostly cabbage. It’s just the culinary experience that differs. Unlike sauerkraut, kimchi is usually spiced, for example.
- Kombucha (a fermented sweet tea)
- Miso & tempeh (different preparations of fermented soy)
The health benefits vary based on the individual strains of bacteria involved in the fermentation, so don’t get too caught up on which is best.
The best one is the one you enjoy, because then you’ll have it regularly!
Feed them plenty of prebiotic fibers
Those probiotics you took? The bacteria in them eat the fiber that you can’t digest without them. So, feed them those sorts of fibers.
Great options include:
- Bananas
- Garlic
- Onions
- Whole grains

Don’t feed them sugar and sweeteners
Sugar and (and, counterintuitively, aspartame) can cause unfortunate gut microbe imbalances. Put simply, they kill some of your friends and feed some of your enemies. For example…
Candida, which we all have in us to some degree, feeds on sugar (including the sugar formed from breaking down alcohol, by the way) and refined carbs. Then it grows, and puts its roots through your intestinal walls, linking with your neural system. Then it makes you crave the very things that will feed it and allow it to put bigger holes in your intestinal walls.
Do not feed the Candida.
Don’t believe us? Read: Candida albicans-Induced Epithelial Damage Mediates Translocation through Intestinal Barriers
(That’s scientist-speak for “Candida puts holes in your intestines, and stuff can then go through those holes”)
And as for how that comes about, it’s like we said:
❝Colonization of the intestine and translocation through the intestinal barrier are fundamental aspects of the processes preceding life-threatening systemic candidiasis. In this review, we discuss the commensal lifestyle of C. albicans in the intestine, the role of morphology for commensalism, the influence of diet, and the interactions with bacteria of the microbiota.❞
Source: Candida albicans as a commensal and opportunistic pathogen in the intestine
The usual five things
- Good diet (Mediterranean Diet is good; plant-based version of it is by far the best for this)
- Good exercise (yes, really)
- Good sleep (helps them, and they’ll help you get better sleep in return)
- Limit or eliminate alcohol consumption (what a shocker)
- Don’t smoke (it’s bad for everything, including gut health)
One last thing you should know:
If you’re used to having animal products in your diet, and make a sudden change to all plants, your gut will object very strongly. This is because your gut microbiome is used to animal products, and a plant-based diet will cause many helpful microbes to flourish in great abundance, and many less helpful microbes will starve and die. And they will make it officially Not Fun™ for you.
So, you have two options to consider:
- Do it anyway, and sit it out (and believe us, you’ll be sitting), get the change over with quickly, and enjoy the benefits and much happier gut that follows.
- Make the change gradual. Reduce portions of animal products slowly, have “Meatless Mondays” etc, and slowly make the change over. This—for most people—is pretty comfortable, easy, and effective.
And remember: the effects of these things we’ve talked about today compound when you do more than one of them, but if you don’t want to take probiotics or really hate kombucha or absolutely won’t consider a plant-based diet or struggle to give up sugar or alcohol, etc… Just do what you can do, and you’ll still have a net improvement!

What causes the itch in mozzie bites? And why do some people get such a bad reaction?
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.
Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting?
Female mosquitoes need blood to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse.
So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others?
Arthur Poulin/Unsplash What happens when a mosquito bites?
Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the carbon dioxide we exhale, our body temperatures and, most importantly, the smell of our skin.
The chemical cocktail of odours from bacteria and sweat on our skin sends out a signal to hungry mosquitoes.
Some people’s skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others.
Once the mosquito has made its way to your skin, things get a little gross.
The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, some designed for sucking and some for spitting.
Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better.
There has even been a suggestion that future medicines could be inspired by the anti-blood clotting properties of mosquito saliva.
A common pest mosquito around the world, Culex quinquefasciatus. Cameron Webb (NSW Health Pathology), CC BY It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like.
Are some people allergic to mosquito spit?
Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all.
For most people, and irrespective of the type of mosquito biting, there is some kind of reaction. Typically there is redness and swelling of the skin that appears within a few hours, but often more quickly, after just a few minutes.
Occasionally, the reaction can cause pain or discomfort. Then comes the itchiness.
Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “skeeter syndrome” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever.
The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the reactions may differ depending on the type of mosquito biting.
We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice.
How best to treat the bites?
Research into treating bites has yet to provide a single easy solution.
There are many myths and home remedies about what works. But there is little scientific evidence supporting their use.
The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help.
There is some evidence that heat may alleviate some of the discomfort.
It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself.
Applying an anti-itch cream may help. If the reactions are severe, antihistamine medications may be required.
To save the scratching, stop the bites
Of course, it’s better not to be bitten by mosquitoes in the first place. Topical insect repellents are a safe, effective and affordable way to reduce mosquito bites.
Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier.
Mosquito coils and other devices can also assist, but should not be entirely relied on to stop bites.
There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than half a million people die from malaria each year.
In Australia, Ross River virus infects more than 5,000 people every year. And in recent years, there have been cases of serious illnesses caused by Japanese encephalitis and Murray Valley encephalitis viruses.

Pine Nuts vs Peanuts – 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 pine nuts to peanuts, we picked the pine nuts.
Why?
An argument could be made for either, honestly, as it depends on what we prioritize the most. These are both very high-calorie foods, and/but are far from empty calories, as they both contain main nutrients. Obviously, if you are allergic to nuts, this one is just not a comparison for you, sorry.
Looking at the macros first, peanuts are higher in protein, carbs, and fiber, while pine nuts are higher in fats—though the fats are healthy, being mostly polyunsaturated, with about a third of the total fats monounsaturated, and a low amount of saturated fat (peanuts have nearly 2x the saturated fat). On balance, we’ll call the macros category a moderate win for peanuts, though.
In terms of vitamins, peanuts have more of vitamins B1, B3, B5, B6, and B9, while pine nuts have more of vitamins A, B2, C, E, K, and choline. All in all, a marginal win for pine nuts.
In the category of minerals, peanuts have more calcium and selenium, while pine nuts have more copper, iron, magnesium, manganese, phosphorus, and zinc. An easy win for pine nuts, even before we take into account that peanuts have nearly 10x as much sodium. And yes, we are talking about the raw nuts, not nuts that have been roasted and salted.
Adding up the categories gives a win for pine nuts—but if you have certain particular priorities, you might still prefer peanuts for the areas in which peanuts are stronger.
Of course, the best solution is to enjoy both!

Sweet Dreams Are Made of THC (Or Are They?)

It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝I’m one of those older folks that have a hard time getting 7 hrs. I know a lot of it my fault…like a few beers at nite…🥰am now trying THC gummies for anxiety, instead of alcohol……less calories 😁how does THC affect our sleep,? Safer than alcohol…..I know your next article 😊😊😊😊❣️😊alot of us older kids do take gummies 😲😲😲thank you❞
Great question! We wrote a little about CBD gummies (not THC) before:
…and went on to explore THC’s health benefits and risks here:
For starters, let’s go ahead and say: you’re right that it’s safer (for most people) than alcohol—but that’s not a strong claim, because alcohol is very bad for pretty much everything, including sleep.
So how does THC measure up when it comes to sleep quality?
Good news: it affects the architecture of sleep in such a way that you will spend longer in deep sleep (delta wave activity), which means you get more restorative and restful sleep!
See also: Alpha, beta, theta: what are brain states and brain waves? And can we control them?
Bad news: it does so at the cost of reducing your REM sleep, which is also necessary for good brain health, and will cause cognitive impairment if you skip too much. Normally, if you are sleep-deprived, the brain will prioritize REM sleep at the cost of other kinds of sleep; it’s that important. However, if you are chemically impaired from getting healthy REM sleep, there’s not much your brain can do to save you from the effects of REM sleep loss.
See: Cannabis, Cannabinoids, and Sleep: a Review of the Literature
This is, by the way, a reason that THC gets prescribed for some sleep disorders, in cases where the initial sleep disruption was because of nightmares, as it will reduce those (along with any other dreams, as collateral damage):
One thing to be careful of if using THC as a sleep aid is that withdrawal may make your symptoms worse than they were to start with:
Updates in the use of cannabis for insomnia
With all that in mind, you might consider (if you haven’t already tried it) seeing whether CBD alone improves your sleep, as while it does also extend time in deep sleep, it doesn’t reduce REM nearly as much as THC does:
👆 this study was paid for by the brand being tested, so do be aware of potential publication bias. That’s not to say the study is necessarily corrupt, and indeed it probably wasn’t, but rather, the publication of the results was dependent on the company paying for them (so hypothetically they could have pulled funding from any number of other research groups that didn’t get the results they wanted, leaving this one to be the only one published). That being said, the study is interesting, which is why we’ve linked it, and it’s a good jumping-off-point for finding a lot of related papers, which you can see listed beneath it.
CBD also has other benefits of its own, even without THC:

Top 10 Causes Of High Blood Pressure
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.
As Dr. Frita Fisher explains, these are actually the top 10 known causes of high blood pressure. Number zero on the list would be “primary hypertension”, which means high blood pressure with no clear underlying cause.
Superficially, this feels a little like the sometime practice of writing the catch-all “heart failure” as the cause of death on a death certificate, because yes, that heart sure did stop beating. But in reality, primary hypertension is most likely often caused by such things as unmanaged chronic stress—something that doesn’t show up on most health screenings.
Dr. Fisher’s Top 10
- Thyroid disease: both hyperthyroidism and hypothyroidism can cause high blood pressure.
- Obstructive sleep apnea: characterized by snoring, daytime sleepiness, and headaches, this condition can lead to hypertension.
- Chronic kidney disease: diseases ranging from diabetic nephropathy to renal vascular disease can cause high blood pressure.
- Elevated cortisol levels: conditions like Cushing’s syndrome or disease, which involve high cortisol levels, can lead to hypertension—as can a lifestyle with a lot of chronic stress, but that’s less readily diagnosed as such than something one can tell from a blood test.
- Elevated aldosterone levels: excess aldosterone from the adrenal glands causes the body to retain salt and water, increasing blood pressure, because more stuff = more pressure.
- Brain tumor: tumors that increase intracranial pressure can cause a rise in blood pressure to ensure adequate brain perfusion. In these cases, the hypertension is keeping you alive—unless it kills you first. If this seems like a strange bodily response, remember that our bodily response to an infection is often fever, to kill off the infection which can’t survive at such high temperatures (but neither can we, so it becomes a game of chicken with our life on the line), so sometimes our body does kill us with one thing while trying to save us from another.
- Coarctation of the aorta: this congenital heart defect results in narrowing of the aorta, leading to hypertension, especially in the upper body.
- Pregnancy: pregnancy can either induce or worsen existing hypertension.
- Obesity: excess weight increases blood flow and pressure on arteries, raising the risk of hypertension and associated conditions, e.g. diabetes etc.
- Drugs: certain medications and recreational drugs (including, counterintuitively, alcohol!) can elevate blood pressure.

A Supplement To Rival St. John’s Wort Against Depression
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.
Do You Feel The SAMe?
S-Adeonsyl-L-Methionone (SAMe) is a chemical found naturally in the body, and/but enjoyed widely as a supplement. The main reasons people take it are:
- Improve mood (antidepressant effect)
- Improve joints (reduce osteoarthritis symptoms)
- Improve liver (detoxifying effect)
Let’s see what the science says for each of those claims…
Does it improve mood?
It seems to perform comparably to St. John’s Wort (which is good; it performs comparably to Prozac).
Best of all, it does this with fewer contraindications (St. John’s Wort has so many contraindications).
Here’s how they stack up:
This looks very promising, though it’d be nice to see a larger body of research, to be sure.
Does it reduce osteoarthritis symptoms?
The good news: it performs comparably to ibuprofen, with fewer side effects!
The bad news: it also performs comparably to placebo!
Read into that what you will about ibuprofen’s usefulness vs OA symptoms.
Read all about it:
S-Adenosylmethionine for osteoarthritis of the knee or hip
If you were hoping for something for OA or similar symptoms, you might like our previous main features:

- Managing Chronic Pain (Realistically!)
- The 7 Approaches To Pain Management
- (Science-Based) Alternative Pain Relief
Does it help against liver disease?
According to adverts for SAMe: absolutely!
According to science: we don’t know
The science for this is so weak that it’d be unworthy of mention if it weren’t for the fact that SAMe is so widely sold as good against hepatotoxicity.
To be clear: maybe it really is great! Science hasn’t yet disproved its usefulness either.
It is popularly assumed to be beneficial due to there being an association between lower levels of SAMe in the body (remember, it is also produced inside our bodies) and development of liver disease, especially cholestasis.
Here’s an example of what pretty much every study we found was like (inconclusive research based mostly on mice):
S-adenosylmethionine in liver health, injury, and cancer
For other options for liver health, consider:
Is it safe?
Safety trials have been done ranging from 3 months to 2 years, with no serious side effects coming to light. So, it appears quite safe.
That said, as with anything, there are contraindications, such as:
- if you have bipolar disorder, skip this unless directed by your health care provider, because it may worsen the symptoms of mania
- if you are on SSRIs or other serotonergic drugs, it may interact with those
- if you are immunocompromised, you might want to skip it can increase the risk of P. carinii growth in such cases
As always, do speak with your doctor/pharmacist for personalized advice.
Summary
SAMe’s evidence-based qualities seem to stack up as follows:
- Against depression: good
- Against osteoarthritis: weak
- Against liver disease: unknown
As for safety, it has been found quite safe for most people.
Where can I get it?
We don’t sell it, but here is an example product on Amazon, for your convenience

Elderly loss of energy
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 Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Please please give some information on elderly loss of energy and how it can be corrected. Please!❞
A lot of that is the metabolic slump described above! While we certainly wouldn’t describe 60 as elderly, and the health impacts from those changes at 45–55 get a gentler curve from 60 onwards… that curve is only going in one direction if we don’t take exceptionally good care of ourselves.
And of course, there’s also a degree of genetic lottery, and external factors we can’t entirely control (e.g. injuries etc).
One factor that gets overlooked a lot, though, is really easy to fix: B-vitamins.
In particular, vitamins B1, B5, B6, and B12. Of those, especially vitamins B1 and B12.
(Vitamins B5 and B6 are critical to health too, but relatively few people are deficient in those, while many are deficient in B1 and/or B12, especially as we get older)
Without going so detailed as to make this a main feature: these vitamins are essential for energy conversion from food, and they will make a big big difference.
You might especially want to consider taking sulbutiamine, which is a synthetic version of thiamin (vitamin B1), and instead of being water-soluble, it’s fat-soluble, and it easily crosses the blood-brain barrier, which is a big deal.
As ever, always check with your doctor because your needs/risks may be different. Also, there can be a lot of reasons for fatigue and you wouldn’t want to overlook something important.
You might also want to check out yesterday’s sponsor, as they offer personalized at-home health testing to check exactly this sort of thing.
❝What are natural ways to lose weight after 60? Taking into account bad knees or ankles, walking may be out as an exercise, running certainly is.❞
Losing weight is generally something that comes more from the kitchen than the gym, as most forms of exercise (except HIIT; see below) cause the metabolism to slow afterwards to compensate.
However, exercise is still very important, and swimming is a fine option if that’s available to you.
A word to the wise: people will often say “gentle activities, like tai chi or yoga”, and… These things are not the same.
Tai chi and yoga both focus on stability and suppleness, which are great, but:
- Yoga is based around mostly static self-support, often on the floor
- Tai chi will have you very often putting most of your weight on one slowly-increasingly bent knee at a time, and if you have bad knees, we’ll bet you winced while reading that.
So, maybe skip tai chi, or at least keep it to standing meditations and the like, not dynamic routines. Qigong, the same breathing exercises used in tai chi, is also an excellent way to improve your metabolism, by the way.
Ok, back onto HIIT:
