Q: Where do I get cucumber extract?
A: You can buy it from BulkSupplements.com (who, despite their name, start at 100g packs)
Alternatively: you want it as a topical ointment (for skin health) rather than as a dietary supplement (for bone and joint health), you can extract it yourself! No, it’s not “just juice cucumbers”, but it’s also not too tricky.

Unlock Your Menopause Type – by Dr. Heather Hirsch
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 featured Dr. Hirsch before, here, and mentioned this book which, at the time, we had not yet reviewed. So, here it is:
What sets this apart from a lot of menopause books is that there’s a lot less “eat these foods and your body will magically stop exhibiting symptoms of menopause” and a lot more clinical observations and then evidence-based recommendations.
Which is not to say don’t eat broccoli and almonds; by all means, they’re great foods and contain valuable nutrients that will help. But it is to say that if your doctor’s prescription is just broccoli and almonds, maybe have those as a snack while you’re looking for a second opinion.
Dr. Hirsch goes through various “menopause types”, but it’s not so much “astrology for gynecologists” and more “here are clusters of menopause symptoms set against timeline of presentation, and they can be categorized into six main ways that between them, cover pretty much all my patients, which have been many”.
So if you, dear reader, are menopausal (including peri- or post-), then the chances are very good that you will see yourself in one of those six sets.
She then goes about how to prioritize relief and safety, and personalize a treatment plan, and maintain the best menopausal care for you, going forward.
The style is easy-reading pop-science, punctuated by clinical science and 35 pages of references. She’s also, unlike a lot of authors in the genre, manifestly not invested in being a celebrity or making a personality cult out of her recommendations; she’s happy to stick to the science and put out good advice.
Bottom line: if you or someone you love is menopausal (including peri- or post-), this is a top-tier book.

Knitting helps Tom Daley switch off. Its mental health benefits are not just for Olympians
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.
Olympian Tom Daley is the most decorated diver in Britain’s history. He is also an avid knitter. At the Paris 2024 Olympics Daley added a fifth medal to his collection – and caught the world’s attention knitting a bright blue “Paris 24” jumper while travelling to the games and in the stands.
At the Tokyo Olympics, where Daley was first spotted knitting, he explained its positive impact on his mental health.
It just turned into my mindfulness, my meditation, my calm and my way to escape the stresses of everyday life and, in particular, going to an Olympics.
The mental health benefits of knitting are well established. So why is someone famous like Daley knitting in public still so surprising?
Africa Voice/Shutterstock Knitting is gendered
Knitting is usually associated with women – especially older women – as a hobby done at home. In a large international survey of knitting, 99% of respondents identified as female.
But the history of yarn crafts and gender is more tangled. In Europe in the middle ages, knitting guilds were exclusive and reserved for men. They were part of a respected Europe-wide trade addressing a demand for knitted products that could not be satisfied by domestic workers alone.
The industrial revolution made the production of clothed goods cheaper and faster than hand-knitting. Knitting and other needle crafts became a leisure activity for women, done in the private sphere of the home.
World Wars I and II turned the spotlight back on knitting as a “patriotic duty”, but it was still largely taken up by women.
During COVID lockdowns, knitting saw another resurgence. But knitting still most often makes headlines when men – especially famous men like Daley or actor Ryan Gosling – do it.
Men who knit are often seen as subverting the stereotype it’s an activity for older women.
Knitting the stress away
Knitting can produce a sense of pride and accomplishment. But for an elite sportsperson like Daley – whose accomplishments already include four gold medals and one silver – its benefits lie elsewhere.
Olympics-level sport relies on perfect scores and world records. When it comes to knitting, many of the mental health benefits are associated with the process, rather than the end result.
Daley says knitting is the “one thing” that allows him to switch off completely, describing it as “my therapy”. https://www.youtube.com/embed/6wwXGOki–c?wmode=transparent&start=0
The Olympian says he could
knit for hours on end, honestly. There’s something that’s so satisfying to me about just having that rhythm and that little “click-clack” of the knitting needles. There is not a day that goes by where I don’t knit.
Knitting can create a “flow” state through rhythmic, repetitive movements of the yarn and needle. Flow offers us a balance between challenge, accessibility and a sense of control.
It’s been shown to have benefits relieving stress in high-pressure jobs beyond elite sport. Among surgeons, knitting has been found to improve wellbeing as well as manual dexterity, crucial to their role.
For other health professionals – including oncology nurses and mental health workers – knitting has helped to reduce “compassion fatigue” and burnout. Participants described the soothing noise of their knitting needles. They developed and strengthened team bonds through collective knitting practices. https://www.youtube.com/embed/dTTJjD_q2Ik?wmode=transparent&start=0 A Swiss psychiatrist says for those with trauma, knitting yarn can be like “knitting the two halves” of the brain “back together”.
Another study showed knitting in primary school may boost children’s executive function. That includes the ability to pay attention, remember relevant details and block out distractions.
As a regular creative practice, it has also been used in the treatment of grief, depression and subduing intrusive thoughts, as well countering chronic pain and cognitive decline.
Knitting is a community
The evidence for the benefits of knitting is often based on self-reporting. These studies tend to produce consistent results and involve large population samples.
This may point to another benefit of knitting: its social aspect.
Knitting and other yarn crafts can be done alone, and usually require simple materials. But they also provide a chance to socialise by bringing people together around a common interest, which can help reduce loneliness.
The free needle craft database and social network Ravelry contains more than one million patterns, contributed by users. “Yarn bombing” projects aim to engage the community and beautify public places by covering objects such as benches and stop signs with wool.
The interest in Daley’s knitting online videos have formed a community of their own.
In them he shows the process of making the jumper, not just the finished product. That includes where he “went wrong” and had to unwind his work.
His pride in the finished product – a little bit wonky, but “made with love” – can be a refreshing antidote to the flawless achievements often on display at the Olympics.

Cardiac Failure Explained – by Dr. Warrick Bishop
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.
The cover of this book makes it look like it’ll be a flashy semi-celebrity doctor keen to sell his personalized protocol, along with eleventy-three other books, but actually, what’s inside this one is very different:
We (hopefully) all know the basics of heart health, but this book takes it a lot further. Starting with the basics, then the things that it’s easy to feel like you should know but actually most people don’t, then into much more depth.
The format is much more like a university textbook than most pop-science books, and everything about the way it’s written is geared for maximum learning. The one thing it does keep in common with pop-science books as a genre is heavy use of anecdotes to illustrate points—but he’s just as likely to use tables, diagrams, callout boxes, emboldening of key points, recap sections, and so forth. And for the most part, this book is very information-dense.
Dr. Bishop also doesn’t just stick to what’s average, and talks a lot about aberrations from the norm, what they mean and what they do and yes, what to do about them.
On the one hand, it’s more information dense than the average reader can reasonably expect to need… On the other hand, isn’t it great to finish reading a book feeling like you just did a semester at medical school? No longer will you be baffled by what is going on in your (or perhaps a loved one’s) cardiac health.
Bottom line: if you’d like to know cardiac health inside out, this book is an excellent place to start.

How Jumping Rope Changes The Human Body
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.
Most popularly enjoyed by professional boxers and six-year-old girls, jumping rope is one of the most metabolism-boosting exercises around:
Just a hop, skip, and a jump away from good health
Maybe you haven’t tried it since your age was in single digits, so, if you do…
What benefits can you expect?
- Improves cardiovascular fitness, equivalent to 30 minutes of running with just 10 minutes of jumping.
- Increases bone density and boosts immunity by aiding the lymphatic system.
- Enhances explosiveness in the lower body, agility, and stamina.
- Improves shoulder endurance, coordination, and spatial awareness.
What kind of rope is best for you?
- Beginner ropes: licorice ropes (nylon/vinyl), beaded ropes for rhythm and durability.
- Advanced ropes: speed ropes (denser, faster materials) for higher speeds and more difficult skills.
- Weighted ropes: build upper body muscles (forearms, shoulders, chest, back).
What length should you get?
- Recommended rope length varies by height (8 ft for 5’0″–5’4″, 9 ft for 5’5″–5’11”, 10 ft for 6’0″ and above).
- Beginners should start with longer ropes for clearance.
What should you learn?
- Initial jump rope skills: start with manageable daily jump totals, gradually increasing as ankles, calves, and feet adapt.
- Further skills: learn the two-foot jump and then the boxer’s skip for efficient, longer sessions and advanced skills. Keep arms close and hands at waist level for a smooth swing.

How To Heal Psoriasis Naturally
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.
Nutritionist Julia Davies explains the gut-skin connection (& how to use it to your advantage) in this video:
Inside out
Psoriasis is a chronic autoimmune skin condition, in which the skin renewal process accelerates from 28 days (normal) to 3–5 days, leading to red, scaly patches. It most commonly affects the outer joints (especially elbows & knees) but can appear anywhere, including the scalp and torso.
Autoimmune diseases are often linked to gut barrier integrity issues, as leaky gut syndrome allows toxins/food particles to penetrate the gut lining, triggering an immune response, which means inflammation.
Standard treatments often include topical or systemic immunosuppressants, such as steroids. Such medications suppress the immune response (and thus the symptoms) but they don’t address root causes.
What to do about it, from the root
As you might imagine, part of the key is a non-inflammatory (or ideally, anti-inflammatory) diet. This means starting by removing likely triggers; gluten sensitivity is common so that’s near the top of the list.
At the very top of the list though is sugar*, which is not only pro-inflammatory but also feeds candida in the gut, which is a major driver of leaky gut, as the fungus puts its roots through your intestines (that’s as bad as it sounds).
*as usual, sugar that comes with adequate fiber, such as whole fruit, is fine. Fruit juice, however, is not.
It is likely to see early improvements within 6 weeks, and significant improvement (such as being mostly symptom-free) can take 6–8 months, so don’t give up if it’s day 3 and you’re not cured yet. This is a marathon not a sprint, and you’ll need to maintain things or the psoriasis may return.
In the meantime, it is recommended to do all you reasonably can to help your gut to repair itself, which means a good amount of fiber, and occasional probiotics. Also, focusing on whole, nutrient-dense foods will of course reduce inflammation and improve energy—which can be a big deal, as psoriasis is often associated with fatigue, both because inflammation itself is exhausting (the body is very active, on a cellular level), and because a poor diet is not invigorating.
Outside of diet, stress is often a trigger for flare-ups, so try to manage that too, of course.

Does intermittent fasting have benefits for our brain?
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.
Intermittent fasting has become a popular dietary approach to help people lose or manage their weight. It has also been promoted as a way to reset metabolism, control chronic disease, slow ageing and improve overall health.
Meanwhile, some research suggests intermittent fasting may offer a different way for the brain to access energy and provide protection against neurodegenerative diseases like Alzheimer’s disease.
This is not a new idea – the ancient Greeks believed fasting enhanced thinking. But what does the modern-day evidence say?
First, what is intermittent fasting?
Our diets – including calories consumed, macronutrient composition (the ratios of fats, protein and carbohydrates we eat) and when meals are consumed – are factors in our lifestyle we can change. People do this for cultural reasons, desired weight loss or potential health gains.
Intermittent fasting consists of short periods of calorie (energy) restriction where food intake is limited for 12 to 48 hours (usually 12 to 16 hours per day), followed by periods of normal food intake. The intermittent component means a re-occurrence of the pattern rather than a “one off” fast.
Food deprivation beyond 24 hours typically constitutes starvation. This is distinct from fasting due to its specific and potentially harmful biochemical alterations and nutrient deficiencies if continued for long periods.
4 ways fasting works and how it might affect the brain
The brain accounts for about 20% of the body’s energy consumption.
Here are four ways intermittent fasting can act on the body which could help explain its potential effects on the brain.
1. Ketosis
The goal of many intermittent fasting routines is to flip a “metabolic switch” to go from burning predominately carbohydrates to burning fat. This is called ketosis and typically occurs after 12–16 hours of fasting, when liver and glycogen stores are depleted. Ketones – chemicals produced by this metabolic process – become the preferred energy source for the brain.
Due to this being a slower metabolic process to produce energy and potential for lowering blood sugar levels, ketosis can cause symptoms of hunger, fatigue, nausea, low mood, irritability, constipation, headaches, and brain “fog”.
At the same time, as glucose metabolism in the brain declines with ageing, studies have shown ketones could provide an alternative energy source to preserve brain function and prevent age-related neurodegeneration disorders and cognitive decline.
Consistent with this, increasing ketones through supplementation or diet has been shown to improve cognition in adults with mild cognitive decline and those at risk of Alzheimer’s disease respectively.
2. Circadian syncing
Eating at times that don’t match our body’s natural daily rhythms can disrupt how our organs work. Studies in shift workers have suggested this might also make us more prone to chronic disease.
Time-restricted eating is when you eat your meals within a six to ten-hour window during the day when you’re most active. Time-restricted eating causes changes in expression of genes in tissue and helps the body during rest and activity.
A 2021 study of 883 adults in Italy indicated those who restricted their food intake to ten hours a day were less likely to have cognitive impairment compared to those eating without time restrictions.
Matching your eating to the active parts of your day may have brain benefits.
Shutterstock3. Mitochondria
Intermittent fasting may provide brain protection through improving mitochondrial function, metabolism and reducing oxidants.
Mitochondria’s main role is to produce energy and they are crucial to brain health. Many age-related diseases are closely related to an energy supply and demand imbalance, likely attributed to mitochondrial dysfunction during ageing.
Rodent studies suggest alternate day fasting or reducing calories by up to 40% might protect or improve brain mitochondrial function. But not all studies support this theory.
4. The gut-brain axis
The gut and the brain communicate with each other via the body’s nervous systems. The brain can influence how the gut feels (think about how you get “butterflies” in your tummy when nervous) and the gut can affect mood, cognition and mental health.
In mice, intermittent fasting has shown promise for improving brain health by increasing survival and formation of neurons (nerve cells) in the hippocampus brain region, which is involved in memory, learning and emotion.
What we eat can affect our brain, and vice versa.
ShutterstockThere’s no clear evidence on the effects of intermittent fasting on cognition in healthy adults. However one 2022 study interviewed 411 older adults and found lower meal frequency (less than three meals a day) was associated with reduced evidence of Alzheimer’s disease on brain imaging.
Some research has suggested calorie restriction may have a protective effect against Alzheimer’s disease by reducing oxidative stress and inflammation and promoting vascular health.
When we look at the effects of overall energy restriction (rather than intermittent fasting specifically) the evidence is mixed. Among people with mild cognitive impairment, one study showed cognitive improvement when participants followed a calorie restricted diet for 12 months.
Another study found a 25% calorie restriction was associated with slightly improved working memory in healthy adults. But a recent study, which looked at the impact of calorie restriction on spatial working memory, found no significant effect.
Bottom line
Studies in mice support a role for intermittent fasting in improving brain health and ageing, but few studies in humans exist, and the evidence we have is mixed.
Rapid weight loss associated with calorie restriction and intermittent fasting can lead to nutrient deficiencies, muscle loss, and decreased immune function, particularly in older adults whose nutritional needs may be higher.
Further, prolonged fasting or severe calorie restriction may pose risks such as fatigue, dizziness, and electrolyte imbalances, which could exacerbate existing health conditions.
If you’re considering intermittent fasting, it’s best to seek advice from a health professional such as a dietitian who can provide guidance on structuring fasting periods, meal timing, and nutrient intake. This ensures intermittent fasting is approached in a safe, sustainable way, tailored to individual needs and goals.
