Black Pepper’s Impressive Anti-Cancer Arsenal (And More)
Piperine, a compound found in Piper nigrum (black pepper, to its friends), has many health benefits. It’s included as a minor ingredient in some other supplements, because it boosts bioavailability. In its form as a kitchen spice, it’s definitely a superfood.
What does it do?
First, three things that generally go together:
These things often go together for the simple reason that oxidative stress, inflammation, and cancer often go together. In each case, it’s a matter of cellular wear-and-tear, and what can mitigate that.
For what it’s worth, there’s generally a fourth pillar: anti-aging. This is again for the same reason. That said, black pepper hasn’t (so far as we could find) been studied specifically for its anti-aging properties, so we can’t cite that here as an evidence-based claim.
Nevertheless, it’s a reasonable inference that something that fights oxidation, inflammation, and cancer, will often also slow aging.
Special note on the anti-cancer properties
We noticed two very interesting things while researching piperine’s anti-cancer properties. It’s not just that it reduces cancer risk and slows tumor growth in extant cancers (as we might expect from the above-discussed properties). Let’s spotlight some studies:
It is selectively cytotoxic (that’s a good thing)
Piperine was found to be selectively cytotoxic to cancerous cells, while not being cytotoxic to non-cancerous cells. To this end, it’s a very promising cancer-sniper:
Piperine as a Potential Anti-cancer Agent: A Review on Preclinical Studies
It can reverse multi-drug resistance in cancer cells
P-glycoprotein, found in our body, is a drug-transporter that is known for “washing out” chemotherapeutic drugs from cancer cells. To date, no drug has been approved to inhibit P-glycoprotein, but piperine has been found to do the job:
Targeting P-glycoprotein: Investigation of piperine analogs for overcoming drug resistance in cancer
What’s this about piperine analogs, though? Basically the researchers found a way to “tweak” piperine to make it even more effective. They called this tweaked version “Pip1”, because calling it by its chemical name,
((2E,4E)-5-(benzo[d][1,3]dioxol-5-yl)-1-(6,7-dimethoxy-3,4-dihydroisoquinolin-2(1 H)-yl)penta-2,4-dien-1-one)
…got a bit unwieldy.
The upshot is: Pip1 is better, but piperine itself is also good.
Other benefits
Piperine does have other benefits too, but the above is what we were most excited to talk about today. Its other benefits include:
- Neuroprotective effects (against Alzheimer’s, Parkinson’s, and more)
- Blood-sugar balancing / antidiabetic effect
- Good for gut microbiome diversity
- Heart health benefits, including cholesterol-balancing
- Boosts bioavailability of other nutrients/drugs

Antioxidant Matcha Snack Bars
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 antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.
You will need
For the base:
- ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
- ⅔ cup chopped dates
For the main part:
- 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
- ½ cup almond milk (or your preferred milk of any kind)
- ½ cup cacao nibs
- 2 tbsp lime juice
- 1 tbsp matcha powder
- 1 tbsp maple syrup (omit if you don’t care for sweetness)
For the topping (optional):
- 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
- Spare cacao nibs, chopped nuts, or anything else you might want on there
Method
(we suggest you read everything at least once before doing anything)
1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.
2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.
3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.
4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.
5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.
6) Serve!
Enjoy!

Semaglutide’s Surprisingly Unexamined Effects
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.
Semaglutide’s Surprisingly Big Research Gap
GLP-1 receptor agonists like Ozempic, Wegovy, and other semaglutide drugs. are fast becoming a health industry standard go-to tool in the weight loss toolbox. When it comes to recommending that patients lose weight, “Have you considered Ozempic?” is the common refrain.
Sometimes, this may be a mere case of kicking the can down the road with regard to some other treatment that it can be argued (sometimes even truthfully) would go better after some weight loss:
How weight bias in health care can harm patients with obesity: Research
…which we also covered in fewer words in the second-to-last item here:
But GLP-1 agonists work, right?
Yes, albeit there’s a litany of caveats, top of which are usually:
- there are often adverse gastrointestinal side effects
- if you stop taking them, weight regain generally ensues promptly
For more details on these and more, see:
…but now there’s another thing that’s come to light:
The dark side of semaglutide’s weight loss
In academia, “dark” is often used to describe “stuff we don’t have much (or in some cases, any) direct empirical evidence of, but for reasons of surrounding things, we know it’s there”.
Well-known examples include “dark matter” in physics and the Dark Ages in (European) history.
In the case of semaglutide and weight loss, a review by a team of researchers (Drs. Sandra Christenen, Katie Robinson, Sara Thomas, and Dominique Williams) has discovered how little research has been done into a certain aspect of GLP-1 agonist’s weight loss effects, namely…
Dietary changes!
There’s been a lot of popular talk about “people taking semaglutide eat less”, but it’s mostly anecdotal and/or presumed based on parts of the mechanism of action (increasing insulin production, reducing glucagon secretions, modulating dietary cravings).
Where studies have looked at dietary changes, it’s almost exclusively been a matter of looking at caloric intake (which has been found to be a 16–39% reduction), and observations-in-passing that patients reported reduction in cravings for fatty and sweet foods.
This reduction in caloric intake, by the way, is not significantly different to the reduction brought about by counselling alone (head-to-head studies have been done; these are also discussed in the research review).
However! It gets worse. Very few studies of good quality have been done, even fewer (two studies) actually had a registered dietitian nutritionist on the team, and only one of them used the “gold standard” of nutritional research, the 24-hour dietary recall test. Which, in case you’re curious, you can read about what that is here:
Dietary Assessment Methods: What Is A 24-Hour Recall?
Of the four studies that actually looked at the macros (unlike most studies), they found that on average, protein intake decreased by 17.1%. Which is a big deal!
It’s an especially big deal, because while protein’s obviously important for everyone, it’s especially important for anyone trying to lose weight, because muscle mass is a major factor in metabolic base rate—which in turn is much important for fat loss/maintenance than exercise, when it comes to how many calories we burn by simply existing.
A reasonable hypothesis, therefore, is that one of the numerous reasons people who quit GLP-1 agonists immediately put fat back on, is because they probably lost muscle mass in amongst their weight loss, meaning that their metabolic base rate will have decreased, meaning that they end up more disposed to put on fat than before.
And, that’s just a hypothesis and it’s a hypothesis based on very few studies, so it’s not something to necessarily take as any kind of definitive proof of anything, but it to say—as the researchers of this review do loudly say—more research needs to be done into this, because this has been a major gap in research so far!
Any other bad news?
While we’re talking research gaps, guess how many studies looked into micronutrient intake changes in people taking GLP-1 agonists?
If you guessed zero, you guessed correctly.
You can find the paper itself here:
What’s the main take-away here?
On a broad, scoping level: we need more research!
On a “what this means for individuals who want to lose weight” level: maybe we should be more wary of this still relatively new (less than 10 years old) “wonder drug”. And for most of those 10 years it’s only been for diabetics, with weight loss use really being in just the past few years (2021 onwards).
In other words: not necessarily any need to panic, but caution is probably not a bad idea, and natural weight loss methods remain very reasonable options for most people.

Mushrooms vs Eggplant – 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 mushrooms to eggplant, we picked the mushrooms.
Why?
First, you may be wondering: which mushrooms? Button mushrooms? White mushrooms? Chestnut mushrooms? Portobello mushrooms? And the answer is yes. Those (and more; it represents most mushrooms that are commonly sold fresh in western supermarkets) are all the same species at different ages; namely, Agaricus bisporus—not to be mistaken for fly agaric, which despite the name, is not even a member of the Agaricus genus, and is in fact Amanita muscari. This is an important distinction, because fly agaric is poisonous, though fatality is rare, and it’s commonly enjoyed recreationally (after some preparation, which reduces its toxicity) for its psychoactive effects. It’s the famous red one with white spots. Anyway, today we will be talking instead about Agaricus bisporus, which is most popular western varieties of “edible mushroom”.
With that in mind, let’s get down to it:
In terms of macros, mushrooms contain more than 3x the protein, while eggplant contains nearly 2x the carbs and 3x the fiber. We’ll call this a tie for macros.
As for vitamins, mushrooms contain more of vitamins B1, B2, B3, B5, B6, B7, B9, B12, D, and choline, while eggplant contains more of vitamins A, E, and K. Most notably for vegans, mushrooms are a good non-animal source of vitamins B12 and D, which nutrients are not generally found in plants. Mushrooms, of course, are not technically plants. In any case, the vitamins category is an easy win for mushrooms.
When it comes to minerals, mushrooms have more copper, iron, phosphorus, potassium, selenium, and zinc, while eggplant has more calcium, magnesium, and manganese. Another easy win for mushrooms.
One final thing worth noting is that mushrooms are a rich source of the amino acid ergothioneine, which has been called a “longevity vitamin” for its healthspan-increasing effects (see our article below).
Meanwhile, in the category of mushrooms vs eggplant, mushrooms don’t leave much room for doubt and are the clear winner here.

Traveling To Die: The Latest Form of Medical Tourism
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 the 18 months after Francine Milano was diagnosed with a recurrence of the ovarian cancer she thought she’d beaten 20 years ago, she traveled twice from her home in Pennsylvania to Vermont. She went not to ski, hike, or leaf-peep, but to arrange to die.
“I really wanted to take control over how I left this world,” said the 61-year-old who lives in Lancaster. “I decided that this was an option for me.”
Dying with medical assistance wasn’t an option when Milano learned in early 2023 that her disease was incurable. At that point, she would have had to travel to Switzerland — or live in the District of Columbia or one of the 10 states where medical aid in dying was legal.
But Vermont lifted its residency requirement in May 2023, followed by Oregon two months later. (Montana effectively allows aid in dying through a 2009 court decision, but that ruling doesn’t spell out rules around residency. And though New York and California recently considered legislation that would allow out-of-staters to secure aid in dying, neither provision passed.)
Despite the limited options and the challenges — such as finding doctors in a new state, figuring out where to die, and traveling when too sick to walk to the next room, let alone climb into a car — dozens have made the trek to the two states that have opened their doors to terminally ill nonresidents seeking aid in dying.
At least 26 people have traveled to Vermont to die, representing nearly 25% of the reported assisted deaths in the state from May 2023 through this June, according to the Vermont Department of Health. In Oregon, 23 out-of-state residents died using medical assistance in 2023, just over 6% of the state total, according to the Oregon Health Authority.
Oncologist Charles Blanke, whose clinic in Portland is devoted to end-of-life care, said he thinks that Oregon’s total is likely an undercount and he expects the numbers to grow. Over the past year, he said, he’s seen two to four out-of-state patients a week — about one-quarter of his practice — and fielded calls from across the U.S., including New York, the Carolinas, Florida, and “tons from Texas.” But just because patients are willing to travel doesn’t mean it’s easy or that they get their desired outcome.
“The law is pretty strict about what has to be done,” Blanke said.
As in other states that allow what some call physician-assisted death or assisted suicide, Oregon and Vermont require patients to be assessed by two doctors. Patients must have less than six months to live, be mentally and cognitively sound, and be physically able to ingest the drugs to end their lives. Charts and records must be reviewed in the state; neglecting to do so constitutes practicing medicine out of state, which violates medical licensing requirements. For the same reason, the patients must be in the state for the initial exam, when they request the drugs, and when they ingest them.
State legislatures impose those restrictions as safeguards — to balance the rights of patients seeking aid in dying with a legislative imperative not to pass laws that are harmful to anyone, said Peg Sandeen, CEO of the group Death With Dignity. Like many aid-in-dying advocates, however, she said such rules create undue burdens for people who are already suffering.
Diana Barnard, a Vermont palliative care physician, said some patients cannot even come for their appointments. “They end up being sick or not feeling like traveling, so there’s rescheduling involved,” she said. “It’s asking people to use a significant part of their energy to come here when they really deserve to have the option closer to home.”
Those opposed to aid in dying include religious groups that say taking a life is immoral, and medical practitioners who argue their job is to make people more comfortable at the end of life, not to end the life itself.
Anthropologist Anita Hannig, who interviewed dozens of terminally ill patients while researching her 2022 book, “The Day I Die: The Untold Story of Assisted Dying in America,” said she doesn’t expect federal legislation to settle the issue anytime soon. As the Supreme Court did with abortion in 2022, it ruled assisted dying to be a states’ rights issue in 1997.
During the 2023-24 legislative sessions, 19 states (including Milano’s home state of Pennsylvania) considered aid-in-dying legislation, according to the advocacy group Compassion & Choices. Delaware was the sole state to pass it, but the governor has yet to act on it.
Sandeen said that many states initially pass restrictive laws — requiring 21-day wait times and psychiatric evaluations, for instance — only to eventually repeal provisions that prove unduly onerous. That makes her optimistic that more states will eventually follow Vermont and Oregon, she said.
Milano would have preferred to travel to neighboring New Jersey, where aid in dying has been legal since 2019, but its residency requirement made that a nonstarter. And though Oregon has more providers than the largely rural state of Vermont, Milano opted for the nine-hour car ride to Burlington because it was less physically and financially draining than a cross-country trip.
The logistics were key because Milano knew she’d have to return. When she traveled to Vermont in May 2023 with her husband and her brother, she wasn’t near death. She figured that the next time she was in Vermont, it would be to request the medication. Then she’d have to wait 15 days to receive it.
The waiting period is standard to ensure that a person has what Barnard calls “thoughtful time to contemplate the decision,” although she said most have done that long before. Some states have shortened the period or, like Oregon, have a waiver option.
That waiting period can be hard on patients, on top of being away from their health care team, home, and family. Blanke said he has seen as many as 25 relatives attend the death of an Oregon resident, but out-of-staters usually bring only one person. And while finding a place to die can be a problem for Oregonians who are in care homes or hospitals that prohibit aid in dying, it’s especially challenging for nonresidents.
When Oregon lifted its residency requirement, Blanke advertised on Craigslist and used the results to compile a list of short-term accommodations, including Airbnbs, willing to allow patients to die there. Nonprofits in states with aid-in-dying laws also maintain such lists, Sandeen said.
Milano hasn’t gotten to the point where she needs to find a place to take the meds and end her life. In fact, because she had a relatively healthy year after her first trip to Vermont, she let her six-month approval period lapse.
In June, though, she headed back to open another six-month window. This time, she went with a girlfriend who has a camper van. They drove six hours to cross the state border, stopping at a playground and gift shop before sitting in a parking lot where Milano had a Zoom appointment with her doctors rather than driving three more hours to Burlington to meet in person.
“I don’t know if they do GPS tracking or IP address kind of stuff, but I would have been afraid not to be honest,” she said.
That’s not all that scares her. She worries she’ll be too sick to return to Vermont when she is ready to die. And, even if she can get there, she wonders whether she’ll have the courage to take the medication. About one-third of people approved for assisted death don’t follow through, Blanke said. For them, it’s often enough to know they have the meds — the control — to end their lives when they want.
Milano said she is grateful she has that power now while she’s still healthy enough to travel and enjoy life. “I just wish more people had the option,” she said.

Bushfire smoke affects children differently. Here’s how to protect them
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.
Bushfires are currently burning in Australian states including Victoria, Tasmania, Western Australia and South Australia. In some areas, fire authorities have warned residents about the presence of smoke.
Bushfire smoke is harmful to our health. Tiny particles of ash can lodge deep in the lungs.
Exposure to this type of smoke may worsen existing conditions such as asthma, and induce a range of health effects from irritation of the eyes, nose and throat to changes in the cardiovascular system.
Public health recommendations during smoke events tend to provide general advice, and don’t often include advice specifically geared at children. But children are not just little adults. They are uniquely vulnerable to environmental hazards such as bushfire smoke for a number of reasons.
Different physiology, different behaviour
Children’s lungs are still developing and maturing.
Airways are smaller in children, especially young children, which is associated with greater rates of particle deposition – when particles settle on the surfaces of the airways.
Children also breathe more air per kilogram of body weight compared with adults, and therefore inhale more polluted air relative to their size.
Further, children’s detoxification systems are still developing, so environmental toxins take longer to effectively clear from their bodies.
Meanwhile, children’s behaviour and habits may expose them to more environmental toxins than adults. For example, they tend to do more physical activity and spend more time outdoors. Higher levels of physical activity lead to more air inhaled per kilogram of body weight.
Also, a normal and important part of children’s early play is exploring their environment, including by putting things in their mouth. This can result in kids ingesting soil, dust and dirt, which often contain environmental contaminants.
For these reasons, it’s important to consider the specific needs of children when providing advice on what to do when there’s smoke in the air.
Keeping our environments healthy
The Australian government offers recommendations for minimising the health risks from exposure to bushfire smoke. The main advice includes staying indoors and keeping doors and windows closed.
This is great advice when the smoke is thick outside, but air pollutants may still accumulate inside the home. So it’s important to air your home once the smoke outside starts to clear. Take advantage of wind changes to open up and get air moving out of the house with a cross breeze.
Kids are natural scientists, so get them involved. For example, you and your child can “rate” the air each hour by looking at a landmark outside your home and rating how clearly you can see it. When you notice the haze is reducing, open up the house and clear the air.
Because air pollutants settle onto surfaces in our home and into household dust, an easy way to protect kids during smoky periods is to do a daily dust with a wet cloth and vacuum regularly. This will remove pollutants and reduce ingestion by children as they play. Frequent hand washing helps too.
Healthy bodies and minds
Research exploring the effects of bushfire smoke exposure on children’s health is sparse. However, during smoke events, we do see an increase in hospital visits for asthma, as well as children reporting irritation to their eyes, nose and throat.
If your child has asthma or another medical condition, ensure they take any prescribed medications on a regular schedule to keep their condition well controlled. This will minimise the risk of a sudden worsening of their symptoms with bushfire smoke exposure.
Make sure any action plans for symptom flare-ups are up to date, and ensure you have an adequate supply of in-date medication somewhere easy to locate and access.
Kids can get worried during bushfires, and fire emergencies have been linked with a reduction in children’s mental health. Stories such as the Birdie’s Tree books can help children understand these events do pass and people help one another in times of difficulty.
Learning more about air pollution can help too. Our group has a children’s story explaining how air pollution affects our bodies and what can help.
It’s also important for parents and caregivers not to get too stressed, as children cope better when their parents manage their own anxiety and help their children do the same. Try to strike a balance between being vigilant and staying calm.
What about masks?
N95 masks can protect the wearer from fine particles in bushfire smoke, but their use is a bit complicated when it comes to kids. Most young children won’t be able to fit properly into an N95 mask, or won’t tolerate the tight fit for long periods. Also, their smaller airways make it harder for young children to breathe through a mask.
If you choose to use an N95 mask for your children, it’s best to save them for instances when high-level outdoor exposure is unavoidable, such as if you’re going outside when the smoke is very thick.
N95 masks should be replaced after around four hours or when they become damp.
If your child has an existing heart or lung condition, consult their doctor before having them wear an N95 mask.
Our team is currently recruiting for a study exploring the effects of bushfire smoke in children. If you live in south east Queensland and are interested in participating in the event of a bushfire or hazard reduction burn near your home, please express your interest here.

How To Build a Body That Lasts – by Adam Richardson
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.
This book is written on a premise, and that premise is: “your age doesn’t define your mobility; your mobility defines your age”.
To this end, we are treated to 328 pages of why and how to improve our mobility (mostly how; just enough on the “why” to keep the motivation flowing).
Importantly, Richardson doesn’t expect that every reader is a regular gym-bunny or about to become one, doesn’t expect you to have several times your bodyweight in iron to life at home, and doesn’t expect that you’ll be doing the vertical splits against a wall any time soon.
Rather, he expects that we’d like to not dislocate a shoulder while putting the groceries away, would like to not slip a disk while being greeted by the neighbor’s dog, and would like to not need a 7-step plan for putting our socks on.
What follows is a guide to “on the good end of normal” mobility that is sustainable for life. The idea is that you might not be winning Olympic gymnastics gold medals in your 90s, but you will be able to get in and out of a car door as comfortably as you did when you were 20, for example.
Bottom line: if you want to be a superathlete, then you might need something more than this book; if you want to be on the healthy end of average when it comes to mobility, and maintain that for the rest of your life, then this is the book for you.
