Many of us may more often need to recover from a day of moving furniture than running a marathon, but the science of recovery can still teach us a lot. The author, herself an endurance athlete and much-decorated science journalist, sets out to do just that.
She explores a lot of recovery methods, and examines whether the science actually backs them up, and if so, to what degree. She also, in true science journalism style, talks to a lot of professionals ranging from fellow athletes to fellow scientists, to get their input too—she is nothing if not thorough, and this is certainly not a book of one person’s opinion with something to sell.
Indeed, on the contrary, her findings show that some of the best recovery methods are the cheapest, or even free. She also looks at the psychological aspect though, and why many people are likely to continue with things that objectively do not work better than placebo.
The style is very easy-reading jargon-free pop-science, while nevertheless being backed up with hundreds of studies cited in the bibliography—a perfect balance of readability and reliability.
Bottom line: for those who wish to be better informed about how to recover quickly and easily, this book is a treasure trove of information well-presented.

Serotonin vs Dopamine (Know The Differences)
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.
Of the various neurotransmitters that people confuse with each other, serotonin and dopamine are the two highest on the list (with oxytocin coming third as people often attribute its effects to serotonin). But, for all they are both “happiness molecules”, serotonin and dopamine are quite different, and are even opposites in some ways:
More than just happiness
Let’s break it down:
Similarities:
- Both are neurotransmitters, neuromodulators, and monoamines.
- Both impact cognition, mood, energy, behavior, memory, and learning.
- Both influence social behavior, though in different ways.
Differences (settle in; there are many):
- Chemical structure:
- Dopamine: catecholamine (derived from phenylalanine and tyrosine)
- Serotonin: indoleamine (derived from tryptophan)
- Derivatives:
- Dopamine → noradrenaline and adrenaline (stress and alertness)
- Serotonin → melatonin (sleep and circadian rhythm)
- Effects on mental state:
- Dopamine: drives action, motivation, and impulsivity.
- Serotonin: promotes calmness, behavioral inhibition, and cooperation.
- Role in memory and learning:
- Dopamine: key in attention and working memory
- Serotonin: crucial for hippocampus activation and long-term memory
Symptoms of imbalance:
- Low dopamine:
- Loss of motivation, focus, emotion, and activity
- Linked to Parkinson’s disease and ADHD
- Low serotonin:
- Sadness, irritability, poor sleep, and digestive issues
- Linked to PTSD, anxiety, and OCD
- High dopamine:
- Excessive drive, impulsivity, addictions, psychosis
- High serotonin:
- Nervousness, nausea, and in extreme cases, serotonin syndrome (which can be fatal)
Brain networks:
- Dopamine: four pathways controlling movement, attention, executive function, and hormones.
- Serotonin: widely distributed across the cortex, partially overlapping with dopamine systems.
Speed of production:
- Dopamine: can spike and deplete quickly; fatigues faster with overuse.
- Serotonin: more stable, releasing steadily over longer periods.
Illustrative examples:
- Coffee boosts dopamine but loses its effect with repeated use.
- Sunlight helps maintain serotonin levels over time.
If you remember nothing else, remember this:
- Dopamine: action, motivation, and alertness.
- Serotonin: contentment, happiness, and calmness.

Osteoarthritis Of The Knee
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? 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
❝Very informative thank you. And made me think. I am a 72 yr old whitewoman, have never used ( or even been offered) HRT since menopause ~15 yrs ago. Now I’m wondering if it would have delayed the onset of osteoarthritis ( knee) and give me more energy in general. And is it wise to start taking hrt after being without those hormones for so long?❞
(this was in response to our article about menopausal HRT)
Thanks for writing! To answer your first question, obviously we can never know for sure now, but it certainly is possible, per for example a large-ish (n=1003) study of women aged 45–64, in which:
- Those with HRT were significantly less likely to have knee arthritis than those without
- However, to enjoy this benefit depended on continued use (those who used it for a bit and then stopped did not enjoy the same results)
- While it made a big difference to knee arthritis, it made only a small (but still beneficial) difference to wrist/hand arthritis.
We could hypothesize that this is because the mechanism of action is more about strengthening the bones (proofing against osteoporosis is one of the main reasons many people take HRT) and cartilage than it is against inflammation directly.
Since the knee is load-bearing and the hand/wrist joints usually are not, this would mean the HRT strengthening the bones makes a big difference to the “wear and tear” aspect of potential osteoarthritis of the knee, but not the same level of benefit for the hand/wrist, which is less about wear and tear and more about inflammatory factors. But that latter, about it being load-bearing, is just this writer’s hypothesis as to why the big difference.
The researchers do mention:
❝In OA the mechanisms by which HRT might act are highly speculative, but could entail changes in cartilage repair or bone turnover, perhaps with cytokines such as interleukin 6, for example.❞
What is clear though, is that it does indeed appear to have a protective effect against osteoarthritis of the knee.
With regard to the timing, the researchers do note:
❝Why as little as three years of HRT should have a demonstrable effect is unclear. Given the difficulty in ascertaining when the disease starts, it is hard to be sure of the importance of the timing of HRT, and whether early or subclinical disease was present.
These results taken together suggest that HRT has a metabolic action that is only effective if given continuously, perhaps by preventing disease initiation; once HRT is stopped there might be a ‘rebound’ effect, explaining the rapid return to normal risk❞
~ Ibid.
You can read the study here:
On whether it is worth it now…
Again, do speak with an endocrinologist because your situation may vary, but:
- hormones are simply messengers, and your body categorically will respond to those messages regardless of age, or time elapsed without having received such a message. Whether it will repair all damage done is another matter entirely, but it would take a biological miracle for it to have no effect at all.
- anecdotally, many women do enjoy life-changing benefits upon starting HRT at your age and older!
(We don’t like to rely on “anecdotally”, but we couldn’t find studies isolating according to “length of time since menopause”—we’ll keep an eye out and if we find something in the future, we’ll mention it!)
Meanwhile, take care!

Can you ‘boost’ your immune system?
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 flu season and a likely winter COVID-19 wave approach, you may encounter both proven and unproven methods claiming to “boost” your immune system. Before you reach for supplements, learn more about how the immune system works, how vaccines give us the best protection against many illnesses, and how some lifestyle factors can help your immune system function properly.
What is the immune system?
The immune system is the body’s first line of defense against invaders like viruses, bacteria, or fungi. You develop immunity—or protection from infection—when your immune system has learned how to recognize an invader and attack it before it makes you sick.
How can you boost your immune system?
You can teach your immune system how to fight back against dangerous invaders by staying up to date on vaccines. This season’s updated flu and COVID-19 vaccines target newer variants and are recommended for everyone 6 months and older.
Vaccines reduce your risk of getting sick and spreading illness to others. Even if you get infected with a disease after you’ve been vaccinated against it, the vaccine will still increase protection against severe illness, hospitalization, and death.
People who have compromised immune systems due to certain health conditions or because they need to take immunosuppressant medications may need additional vaccine doses.
Find out which vaccines you and your children need by using the CDC’s Adult Vaccine Assessment Tool and Child and Adolescent Vaccine Assessment Tool. Talk to your health care provider about the best vaccines for your family.
Find pharmacies offering updated flu and COVID-19 vaccines by visiting Vaccines.gov.
Can supplements boost your immune system?
Many vitamin, mineral, and herbal supplements that are marketed as “immune boosting” have little to no effect on your immune system. Research is split on whether some of these supplements—like vitamin C, vitamin D, and zinc—are capable of helping your body fight infections.
Plus, the Food and Drug Administration typically does not review supplements until after they have reached store shelves, and companies can sell supplements without notifying the FDA. This means that supplements may not be accurately labeled.
Eating a diverse diet rich in fruits and vegetables is the best way for most people to absorb nutrients that support optimal immune system function. People with certain health conditions and deficiencies may need specific supplements prescribed by a health care provider. For example, people with anemia may need iron supplements in order to maintain appropriate iron levels.
Before you begin taking a new supplement, talk to your health care provider, as some supplements may interact with medications you are taking or worsen certain health conditions.
Can lifestyle factors strengthen your immune system?
Based on current evidence, there is no direct link between lifestyle changes and enhanced immunity to infections. However, maintaining a healthy lifestyle through the following practices can help ensure that your immune system functions as it should:
- Eat a diet rich in fruits and vegetables.
- Exercise regularly.
- Don’t smoke.
- Limit or eliminate alcohol consumption.
- Get seven or more hours of sleep per night.
- Reduce stress.
Taking steps to avoid contact with germs also reduces your risk of getting sick. Safer sex barriers like condoms protect against HIV, while wearing a high-quality, well-fitting mask—especially in high-risk environments—protects against COVID-19. Both of these illnesses can reduce your production of white blood cells, which protect against infection.
For more information, talk to your health care provider.

Gut-Healthy Sunset Soup
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-called for its gut-healthy ingredients, and its flavor profile being from the Maghreb (“Sunset”) region, the western half of the N. African coast.
You will need
- 1 can chickpeas (do not drain)
- 1 cup low-sodium vegetable stock
- 1 small onion, finely chopped
- 1 carrot, finely chopped
- 2 tbsp sauerkraut, drained and chopped (yes, it is already chopped, but we want it chopped smaller so it can disperse evenly in the soup)
- 2 tbsp tomato paste
- 1 tbsp harissa paste (adjust per your heat preference)
- 1 tbsp ras el-hanout
- ¼ bulb garlic, crushed
- Juice of ½ lemon
- ¼ tsp MSG or ½ tsp low-sodium salt
- Extra virgin olive oil
- Optional: herb garnish; we recommend cilantro or flat-leaf parsley
Method
(we suggest you read everything at least once before doing anything)
1) Heat a little oil in a sauté pan or similar (something suitable for combination cooking, as we’ll be frying first and then adding liquids), and fry the onion and carrot until the onion is soft and translucent; about 5 minutes.
2) Stir in the garlic, tomato paste, harissa paste, and ras el-hanout, and fry for a further 1 minute.
3) Add the remaining ingredients* except the lemon juice. Bring to the boil and then simmer for 5 minutes.
*So yes, this includes adding the “chickpea water” also called “aquafaba”; it adds flavor and also gut-healthy fiber in the form of oligosaccharides and resistant starches, which your gut microbiota can use to make short-chain fatty acids, which improve immune function and benefit the health in more ways than we can reasonably mention as a by-the-way in a recipe.
4) Stir in the lemon juice, and serve, adding a herb garnish if you wish.
Enjoy!

Broccoli Sprouts & Sulforaphane
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? 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 😎
❝How much science is there behind sulforaphane / broccoli spirits and its health claims??❞
So, first of all, what it is: sulforaphane is a compound found in Brassica oleracea, of which species broccoli is a cultivar. It’s found in the other Brassica oleracea cultivars too (e.g. cauliflower, various cabbages, Brussels sprouts, kale, etc), but for whatever reason*, most research has been on broccoli and broccoli sprouts.
*Likely the reason is: research begets research—it’s easier to get funding to expand upon previous research, than it is to break ground on researching a different plant, where for the first third of your paper you have almost no existing scientific literature to cite. So once they got started on broccoli sprouts, everything else has been broccoli sprouts too.
And for clarity on what broccoli sprouts are: this means that when broccoli seeds have been germinated and just begun to sprout, they are harvested and eaten. That’s the one-line explanation, anyway; there’s a little more to it than that, so anyone interested should check out our previous main feature:
Good Things Come In Small Packages: Sprout Your Seeds, Grains, Beans, Etc
…and for more depth than we have room for in a one-page article, check out this book we reviewed:
The Sprout Book: Tap Into The Power Of The Planet’s Most Nutritious Food – by Doug Evans
One thing that the science is clear on: sprouts of a given plant indeed have much higher general nutritional density than their “adult” siblings. And in the case of sulforaphane specifically, it’s about 100x higher in broccoli sprouts than in adult broccoli:
Broccoli or Sulforaphane: Is It the Source or Dose That Matters? ← we suggest skipping down to the section “broccoli-based clinical trials”
So, that prompts the next question: do we care?
In other words: is sulforaphane really particularly important?
Sulforaphane vs cancer
The most well-evidenced health-giving property of sulforaphane is its anticancer activity:
Brassicaceae-Derived Anticancer Agents: Towards a Green Approach to Beat Cancer
A lot of the research there is epidemiological rather than RCTs, and where there are RCTs, they are mostly small ones, like this 10-person broccoli soup study about bioavailability (rather than the effects themselves):
Bioavailability of Glucoraphanin and Sulforaphane from High-Glucoraphanin Broccoli
To get into sulforaphane’s anticancer potential in seriousness, we have to look at a lot of in-vitro studies trialling it to limit carcinogenesis, or to shrink tumors with it, or specifically targetting cancer stem cells with it, which make for quite compelling reading:
A quick aside: if you’re reading that and thinking “Why is sonic the hedgehog in here?” it’s because after the observation of the influence of certain genes that influence cuticular denticles (the growth of spikes) on fruit fly larvae (bearing in mind the fruit fly Drosophila melanogaster is used for so much first- or second-line genetic research, being either the go-to or the go-to after the nematode C. elegans) caused the whole group of genes to get called “hedgehog genes” and then it became scientific convention to name each newly researched gene in that set after a different kind of hedgehog. One of them, instead of being named after a real-world hedgehog species like the others, got named after the videogame character.
Unfortunately, this now means that because the gene is associated with a certain congenital brain disorder, sometimes a doctor has to explain to a family that the reason their baby has a brain defect is because of a mutated sonic hedgehog.
Ok, back to talking about cancer. Let’s just quickly drop a few more papers so it’s clear that this is well-established:
- Multi-targeted prevention of cancer by sulforaphane ← this shows how it works on the cellular level
- Cruciferous vegetables: dietary phytochemicals for cancer prevention ← this shows how it works on the population level
However, that’s not the only established benefit:
❝SFN has other beneficial effects in addition to cancer protection. SFN exhibits neuroprotective effects and is implemented in treating conditions such as traumatic brain injury, Alzheimer’s disease and Parkinson’s disease.❞
Source: Sulforaphane in broccoli: The green chemoprevention!! Role in cancer prevention and therapy
Now, after the extract we quoted above, the rest of the section “other health benefits of sulforaphane” includes a lot of speculation, weak science, and/or things attributable to other phytochemicals in broccoli, including various polyphenols, vitamins, and minerals.
About those broccoli spirits
Ok, we know it was a typo, but… Actually, there is something worth mentioning here, and that’s that sulforaphane is only activated when glucoraphanin (its inactive form) comes into contact with myrosinase (an enzyme that’s only released when the plant is damaged).
In other words, it’s necessary to injure the broccoli before consuming it, in order to release the
spiritsmyrosinase. Now, while very few people are out there swallowing adult broccoli plants whole, it could well happen that people might wolf down uncut broccoli sprouts, since they are only small, after all.For this reason, it’s best that broccoli, even if it’s broccoli sprouts, be cut while raw before consumption.
In terms of cooking, heat in excess of 140℃ / 284℉ will destroy the glucoraphanin, and less/no glucoraphanin means less/no sulforaphane.
So, enjoying them raw or lightly steaming them seems to be best for this purpose:
Impact of thermal processing on sulforaphane yield from broccoli (Brassica oleracea L. ssp. italica)
Just want a supplement?
Many studies (including some cited by the research reviews we cited above) deal with sulforaphane in extract form, rather than whole plants, so there’s no shame in taking it that way if you’re not a fan of broccoli.
We don’t sell it, but here for your convenience is an example product on Amazon 😎
Enjoy!

Gut Feelings – by Dr Will Cole
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.
More and more, science is uncovering links between our gut health and the rest of our health—including our mental health! We all know “get some fiber and consider probiotics”, but what else is there that we can do?
Quite a lot, actually. And part of it, which Dr. Cole also explores, is the fact that the gut-brain highway is a two-way street!
The book looks a lot especially at the particular relationship between shame and eating. The shame need not initially be about eating, though it can certainly end up that way too. But any kind of shame—be it relating to one’s body, work, relationship, or anything else, can not only have a direct effect on the gut, but indirect too:
Once our “eating our feelings” instinct kicks in, things can spiral from there, after all.
So, Dr. Cole walks us through tackling this from both sides—nutrition and psychology. With chapters full of tips and tricks, plus a 21-day plan (not a diet plan, a habit integration plan), this book hits shame (and inflammation, incidentally) hard and leads us into much healthier habits and cycles.
In short: if you’d like to have a better relationship with your food, improve your gut health, and/or reduce inflammation, this is definitely a book for you!
