Polycystic ovary syndrome, PCOS, affects very many people; around 1 in 5 women. It can show up unexpectedly, and usually the first-identified sign is irregular vaginal bleeding. We say “vaginal” rather than “menstrual” as it’s not technically menses, although it’ll look (and can feel) the same.
Like many “affects mostly women” conditions, science’s general position is “we don’t know what causes it or how to cure it”.
Quick book recommendation before we continue:
Unwell Women: Misdiagnosis and Myth in a Man-Made World – by Dr. Elinor Cleghorn
…is a top-tier book about medical misogyny. We’d say more here, but well, you can read our review there 🙂
What doesn’t work
Since PCOS is characterized by excessive androgen production, it is reasonable to expect that foods containing phytoestrogens (such as soy) may help. They won’t. The human body can’t use those as estrogen, and in fact, consuming unusually large quantities of phytoestrogens can actually get in the way of your own (or bioidentical) estrogen, by competing for the same receptors but not really doing the job.
But, you won’t get that problem from moderate consumption of soy; the warning is more for those tempted to self-medicate with megadoses, or are opting for dubious supplements such as Pueraria mirifica ← will have to do a research review on that one of these days, but suffice it to say meanwhile, it has some serious drawbacks

What can work
There are some supplement-based approaches that actually can help, and those are the ones that rather than trying to manufacture estrogen out of thin air, work to reduce testosterone and/or reduce the conversion of free testosterone to its more potent form, dihydrogen testosterone (DHT); here are two examples:
- Licorice, Digestion, & Hormones
- One Man’s Saw Palmetto Is Another Woman’s Serenoa Repens ← this one has the most evidence of the two
What will work
…or at least, barring additional confounding factors, what the evidence strongly supports working. Here’s where we get into diet properly, and there are three main dietary approaches:
Low-GI diet: focus on high-fiber, low-carb foods (e.g. whole grains, legumes, berries, leafy greens). Eating this way results in improved insulin sensitivity, lower fasting insulin, cholesterol, triglycerides, waist circumference, and (for women) yes, lower testosterone levels.
See: What Do The Different Kinds Of Fiber Do? 30 Foods That Rank Highest
High antioxidant diet: focus on foods rich in antioxidants (e.g. vitamin A, α-tocopherol specifically, vitamins C and D, and polyphenols) as these lower PCOS incidence.
See: 21 Most Beneficial Polyphenols & What Foods Have Them
Ketogenic diet: focus on high-fat, very low-carb foods (e.g. fatty fish, dairy, leafy greens). This significantly reduces androgen levels, improves insulin sensitivity, and regulates hormones. But… It’s recommended for short-term use only due to its negative health impacts from poor (i.e. narrow) nutritional coverage:
See: Ketogenic Diet: Burning Fat, Or Burning Out?
It is also reasonable to supplement, for example:
❝Omega-3 fatty acids and vitamin D have powerful anti-inflammatory and antioxidant properties that significantly improve insulin sensitivity and reduce androgen levels in metabolic syndromes like PCOS. A higher intake of omega-3 and vitamin E also alleviates mental health parameters and gene expression of PPAR-γ, IL-8, and TNF-α in women with PCOS.
Dietary supplements, such as antioxidants like N-acetylcysteine (NAC), vitamin D, inositol, and omega-3 fatty acids, and mineral supplements (zinc, magnesium selenium, and chromium) help in reducing insulin resistance. These supplements also enhance ovulatory function and decrease inflammation in PCOS patients.
Omega-3 fatty acid supplements improve biochemical parameters LH, LH/FSH, lipid profiles, and adiponectin levels and regularize the menstrual cycle in women with PCOS. A recent RCT also indicated that probiotic/symbiotic supplementation significantly improves triglyceride, insulin, and HDL levels in women with PCOS.❞

Pistachios vs Pecans – 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 pistachios to pecans, we picked the pistachios.
Why?
Firstly, the macronutrients: pistachios have twice as much protein and fiber. Pecans have more fat, though in both of these nuts the fats are healthy.
The category of vitamins is an easy win for pistachios, with a lot more of vitamins A, B1, B2, B3, B6, B9, C, and E. Especially the 8x vitamin A, 7x vitamin B6, 4x vitamin C, and 2x vitamin E, and as the percentages are good too, these aren’t small differences. Pecans, meanwhile, boast only a little more vitamin B5 (pantothenic acid, the one whose name means “it’s everywhere”, because that’s how easy it is to get it).
In terms of minerals, pistachios have more calcium, iron, phosphorus, potassium, and selenium, while pecans have more manganese and zinc. So, a fair win for pistachios on this one.
Adding up the three different kinds of win for pistachios means that *drumroll* pistachios win overall, and it’s not close.
As ever, do enjoy both though, because diversity is healthy!

The Drug & Supplement Combo That Reverses Aging
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.
So far, its effects have been dramatic (in a good way) in mice; human trials are now underway.
How does it work?
It builds from previous work, in which a Japanese research team created an “anti-aging vaccine”, that responded to a problem more specific than aging as a whole, namely atherosclerosis.
They found that a certain* protein was upregulated (i.e., it was made at a greater rate resulting in greater quantities) in patients (mouse and human alike) with atherosclerosis. So, they immunized the mice against that protein, and long story short, everything improved for them, from their atherosclerosis to general markers of aging—including growing back fur that had been lost due to age-related balding (just like in humans). They also lived longer, as is to be expected of a mouse who is now biologically younger.
*To avoid being mysterious: it was glycoprotein nonmetastatic melanoma protein B, known to its friends as GPNMB.
You may be wondering: how can one be immunized against a protein? If so, do bear in mind, a virus is also a protein. In this case, they developed an RNA vaccine, that works in a similar way to the COVID vaccines we all know and love (albeit with a different target).
You can read about this in abundant detail here: Senolytic vaccination improves normal and pathological age-related phenotypes and increases lifespan in progeroid mice
Hot on the heels of that, new approaches were found, including…
The combination
We’ll not keep you waiting; the combination is dasatinib plus quercetin, or else fisetin alone.
It’s about killing senescent (aging) “zombie cells” while sparing healthy cells, which that drug (dasatinib) and those supplements (quercetin and fisetin) do.
The researchers noted:
❝Senescent cells are resistant to apoptosis, which is governed through the upregulation of senescent cell anti-apoptotic pathways (SCAPs). Compounds were subsequently identified that disrupted the SCAPs, inducing death of senescent cells while leaving healthy cells unaffected. Forty-six potential senolytic agents were discovered through this process. To advance translational efforts, the majority of research has focused on agents with known safety profiles and limited off-target effects (Kirkland and Tchkonia, 2020).
The best characterized senolytic agents are dasatinib, a tyrosine kinase inhibitor approved for use in humans for cancer treatment, and quercetin, a naturally occurring plant flavonoid. The agents have a synergistic effect, making their combination more potent for senescent cell clearance (Zhu et al., 2015). As senescent cells do not divide and accumulate over a period of weeks, they can be administered using an intermittent approach, which further serves to reduce the risk of side effects (Kirkland and Tchkonia, 2020).
In preclinical trials, the combination of dasatinib and quercetin (D + Q) have been found to alleviate numerous chronic medical conditions including vascular stiffness, osteoporosis, frailty, and hepatic stenosis❞
Source: A geroscience motivated approach to treat Alzheimer’s disease: Senolytics move to clinical trials
As to how they expanded on this research:
❝In our study, oral D + Q were intermittently administered to tau transgenic mice with late-stage pathology (approximated to a 70-year-old human with advanced AD) (Musi et al., 2018). The treatment effectively reduced cellular senescence and associated senescence-associated secretory phenotype incidence. The 35 % reduction in neurofibrillary tangles was accompanied by enhanced neuron density, decreased ventricular enlargement, diminished tau accumulation, and restoration of aberrant cerebral blood flow. A subsequent preclinical study validated the findings, reporting that intermittently administered D + Q cleared senescent cells in the central nervous system, reduced amyloid-β plaques, attenuated neuroinflammation, and enhanced cognition❞
Source: Ibid.
And now taking it to humans:
❝The first clinical trial of D + Q for early-stage Alzheimer’s Disease (AD) has completed enrollment (Gonzales et al., 2021). The primary aim of the open-label pilot study was to examine the central nervous system penetrance of D and Q in a small sample of older adults with early-stage AD (NCT04063124). In addition, two placebo-controlled trials of D + Q for neurodegenerative disease are underway (NCT04685590 and NCT04785300).
One of the trials in development is a multi-site, double-blind, randomized, placebo-controlled study of senolytic therapy in older adults with amnestic mild cognitive impairment (MCI) or early-stage dementia (Clinical Dementia Rating Scale (CDR) Global 0.5–1) due to AD (elevated CSF total tau/Aβ42 ratio).
The treatment regimen will consist of 12-weeks of intermittently administered oral D + Q.❞
Source: Ibid.
The study is actually completed now, but its results are not yet published (again, at time of writing). Which means: they have the data, and now they’re writing the paper.
We look forward to providing an update about that, when the paper is published!
In the meantime…
Dasatinib is a drug usually prescribed to people with certain kinds of leukemia, and suffice it to say, it’s prescription-only. And unlike drugs that are often prescribed off-label (such as metformin for weight loss), getting your doctor to prescribe you an anticancer drug is unlikely unless you have the cancer in question.
You may be wondering: how is an anticancer drug helpful against aging? And the answer is that cancer and aging are very interrelated, and both have to do with “these old cells just won’t die, and are using the resources needed for young healthy cells”. So in both cases, killing those “zombie cells” while sparing healthy ones, is what’s needed. However, your doctor will probably not buy that as a reason to prescribe you a drug that is technically chemotherapy.
Quercetin, on the other hand, is a readily-available supplement, as is fisetin, and both have glowing (in a good way) safety profiles.

What’s the difference between a heart attack and cardiac arrest? One’s about plumbing, the other wiring
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.
In July 2023, rising US basketball star Bronny James collapsed on the court during practice and was sent to hospital. The 18-year-old athlete, son of famous LA Lakers’ veteran LeBron James, had experienced a cardiac arrest.
Many media outlets incorrectly referred to the event as a “heart attack” or used the terms interchangeably.
A cardiac arrest and a heart attack are distinct yet overlapping concepts associated with the heart.
With some background in how the heart works, we can see how they differ and how they’re related.
Explode/Shutterstock Understanding the heart
The heart is a muscle that contracts to work as a pump. When it contracts it pushes blood – containing oxygen and nutrients – to all the tissues of our body.
For the heart muscle to work effectively as a pump, it needs to be fed its own blood supply, delivered by the coronary arteries. If these arteries are blocked, the heart muscle doesn’t get the blood it needs.
This can cause the heart muscle to become injured or die, and results in the heart not pumping properly.
Heart attack or cardiac arrest?
Simply put, a heart attack, technically known as a myocardial infarction, describes injury to, or death of, the heart muscle.
A cardiac arrest, sometimes called a sudden cardiac arrest, is when the heart stops beating, or put another way, stops working as an effective pump.
In other words, both relate to the heart not working as it should, but for different reasons. As we’ll see later, one can lead to the other.
Why do they happen? Who’s at risk?
Heart attacks typically result from blockages in the coronary arteries. Sometimes this is called coronary artery disease, but in Australia, we tend to refer to it as ischaemic heart disease.
The underlying cause in about 75% of people is a process called atherosclerosis. This is where fatty and fibrous tissue build up in the walls of the coronary arteries, forming a plaque. The plaque can block the blood vessel or, in some instances, lead to the formation of a blood clot.
Atherosclerosis is a long-term, stealthy process, with a number of risk factors that can sneak up on anyone. High blood pressure, high cholesterol, diet, diabetes, stress, and your genes have all been implicated in this plaque-building process.
Other causes of heart attacks include spasms of the coronary arteries (causing them to constrict), chest trauma, or anything else that reduces blood flow to the heart muscle.
Regardless of the cause, blocking or reducing the flow of blood through these pipes can result in the heart muscle not receiving enough oxygen and nutrients. So cells in the heart muscle can be injured or die.
Here’s a simple way to remember the difference. Author provided But a cardiac arrest is the result of heartbeat irregularities, making it harder for the heart to pump blood effectively around the body. These heartbeat irregularities are generally due to electrical malfunctions in the heart. There are four distinct types:
- ventricular tachycardia: a rapid and abnormal heart rhythm in which the heartbeat is more than 100 beats per minute (normal adult, resting heart rate is generally 60-90 beats per minute). This fast heart rate prevents the heart from filling with blood and thus pumping adequately
- ventricular fibrillation: instead of regular beats, the heart quivers or “fibrillates”, resembling a bag of worms, resulting in an irregular heartbeat greater than 300 beats per minute
- pulseless electrical activity: arises when the heart muscle fails to generate sufficient pumping force after electrical stimulation, resulting in no pulse
- asystole: the classic flat-line heart rhythm you see in movies, indicating no electrical activity in the heart.
Remember this flat-line rhythm from the movies? It’s asystole, when there’s no electrical activity in the heart. Kateryna Kon/Shutterstock Cardiac arrest can arise from numerous underlying conditions, both heart-related and not, such as drowning, trauma, asphyxia, electrical shock and drug overdose. James’ cardiac arrest was attributed to a congenital heart defect, a heart condition he was born with.
But among the many causes of a cardiac arrest, ischaemic heart disease, such as a heart attack, stands out as the most common cause, accounting for 70% of all cases.
So how can a heart attack cause a cardiac arrest? You’ll remember that during a heart attack, heart muscle can be damaged or parts of it may die. This damaged or dead tissue can disrupt the heart’s ability to conduct electrical signals, increasing the risk of developing arrhythmias, possibly causing a cardiac arrest.
So while a heart attack is a common cause of cardiac arrest, a cardiac arrest generally does not cause a heart attack.
What do they look like?
Because a cardiac arrest results in the sudden loss of effective heart pumping, the most common signs and symptoms are a sudden loss of consciousness, absence of pulse or heartbeat, stopping of breathing, and pale or blue-tinged skin.
But the common signs and symptoms of a heart attack include chest pain or discomfort, which can show up in other regions of the body such as the arms, back, neck, jaw, or stomach. Also frequent are shortness of breath, nausea, light-headedness, looking pale, and sweating.
What’s the take-home message?
While both heart attack and cardiac arrest are disorders related to the heart, they differ in their mechanisms and outcomes.
A heart attack is like a blockage in the plumbing supplying water to a house. But a cardiac arrest is like an electrical malfunction in the house’s wiring.
Despite their different nature both conditions can have severe consequences and require immediate medical attention.

Eyes for Alzheimer’s Diagnosis: New?

Have something you’d like to ask us, or ask us to look into? Hit reply to any of our emails, or use the feedback widget at the bottom, and a Real Human™ will be glad to read it!
Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.
(this is in response to last week’s piece on lutein, eyes, and brain health)
We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:

Tempeh vs Tofu – 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 tempeh to tofu, we picked the tempeh.
Why?
Per 100g, tempeh has about 1.5x as many calories, about 2x as much protein, about 3x as much fiber, and about 4x the carbohydrates.
Which latter sounds like a lot, but really, the amounts here are small—tempeh is under 12% carbohydrates, and most of that is treated by the body as fiber (e.g. it’s a resistant starch).
Both have no sugar, and both have more or less the same (tiny) amount of fat.
Micronutrients, you ask? As they’re both made from soybeans, the micronutrient profiles are similar, but exact amounts will depend on the method used, so by all means check labels if comparing products in store. By and large, there’s usually not much difference, though.
You can see sample stats here:
In summary
Both are great, and/but tempeh is the more nutrient-dense of the two.
Therefore, tempeh is the healthier option, unless you are on a very strictly calorie-controlled diet, in which case, tofu will give you more quantity per calorie.
Enjoy!

Figs vs Passion Fruit – 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 figs to passion fruit, we picked the passion fruit.
Why?
Both are top-tier fruits! But the passion fruit is just that bit more passionate about delivering healthy nutrients:
In terms of macros, passion fruit has slightly more carbs, notably more protein, and a lot more fiber, giving it the win in this category.
In the category of vitamins, figs have more of vitamins B1, B5, B6, E, and K, while passion fruit has more of vitamins A, B2, B3, B9, C, and choline, making for a marginal win by the numbers for passion fruit here.
When it comes to minerals, figs have more calcium, manganese, and zinc, while passion fruit has more copper, iron, magnesium, phosphorus, potassium, and selenium. A clearer win for passion fruit this time.
Adding up the sections makes for an easy overall win for passion fruit, but again, figs are really a top-tier fruit too; passion fruit just beats them! By all means enjoy either or both; diversity is good!
