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
We had several requests pertaining to veganism, meatless mondays, and substitutions in recipes—so we’re going to cover those on a different day!
As for questions we’re answering today…
Q: Is there any data on immediate and long term effects of running marathons in one’s forties?
An interesting and very specific question! We didn’t find an overabundance of studies specifically for the short- and long-term effects of marathon-running in one’s 40s, but we did find a couple of relevant ones:
The first looked at marathon-runners of various ages, and found that…
- there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
- the majority of middle-aged and elderly athletes have training histories of less than seven years of running
From which they concluded:
❝The present findings strengthen the concept that considers aging as a biological process that can be considerably speeded up or slowed down by multiple lifestyle related factors.❞
See the study: Performance, training and lifestyle parameters of marathon runners aged 20–80 years: results of the PACE-study
The other looked specifically at the impact of running on cartilage, controlled for age (45 and under vs 46 and older) and activity level (marathon-runners vs sedentary people).
The study had the people, of various ages and habitual activity levels, run for 30 minutes, and measured their knee cartilage thickness (using MRI) before and after running.
They found that regardless of age or habitual activity level, running compressed the cartilage tissue to a similar extent. From this, it can be concluded that neither age nor marathon-running result in long-term changes to cartilage response to running.
Or in lay terms: there’s no reason that marathon-running at 40 should ruin your knees (unless you are doing something wrong).
That may or may not have been a concern you have, but it’s what the study looked at, so hey, it’s information.
Here’s the study: Functional cartilage MRI T2 mapping: evaluating the effect of age and training on knee cartilage response to running
Q: Information on [e-word] dysfunction for those who have negative reactions to [the most common medications]?
When it comes to that particular issue, one or more of these three factors are often involved:
- Hormones
- Circulation
- Psychology
The most common drugs (that we can’t name here) work on the circulation side of things—specifically, by increasing the localized blood pressure. The exact mechanism of this drug action is interesting, albeit beyond the scope of a quick answer here today. On the other hand, the way that they work can cause adverse blood-pressure-related side effects for some people; perhaps you’re one of them.
To take matters into your own hands, so to speak, you can address each of those three things we just mentioned:
Hormones
Ask your doctor (or a reputable phlebotomy service) for a hormone test. If your free/serum testosterone levels are low (which becomes increasingly common in men over the age of 45), they may prescribe something—such as testosterone shots—specifically for that.
This way, it treats the underlying cause, rather than offering a workaround like those common pills whose names we can’t mention here.
Circulation
Look after your heart health; eat for your heart health, and exercise regularly!
Cold showers/baths also work wonders for vascular tone—which is precisely what you need in this matter. By rapidly changing temperatures (such as by turning off the hot water for the last couple of minutes of your shower, or by plunging into a cold bath), your blood vessels will get practice at constricting and maintaining that constriction as necessary.
Psychology
[E-word] dysfunction can also have a psychological basis. Unfortunately, this can also then be self-reinforcing, if recalling previous difficulties causes you to get distracted/insecure and lose the moment. One of the best things you can do to get out of this catch-22 situation is to not worry about it in the moment. Depending on what you and your partner(s) like to do in bed, there are plenty of other equally respectable options, so just switch track!
Having a conversation about this in advance will probably be helpful, so that everyone’s on the same page of the script in that eventuality, and it becomes “no big deal”. Without that conversation, misunderstandings and insecurities could arise for your partner(s) as well as yourself (“aren’t I desirable enough?” etc).
So, to recap, we recommend:
- Have your hormones checked
- Look after your circulation
- Make the decision to have fun!

Vaccines and cancer: The myth that won’t die
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.
Two recent studies reported rising cancer rates among younger adults in the U.S. and worldwide. This prompted some online anti-vaccine accounts to link the studies’ findings to COVID-19 vaccines.
But, as with other myths, the data tells a very different story.
What you need to know
- Baseless claims that COVID-19 vaccines cause cancer have persisted online for several years and gained traction in late 2023.
- Two recent reports finding rising cancer rates among younger adults are based on pre-pandemic cancer incidence data. Cancer rates in the U.S. have been on the rise since the 1990s.
- There is no evidence of a link between COVID-19 vaccination and increased cancer risk.
False claims about COVID-19 vaccines began circulating months before the vaccines were available. Chief among these claims was misinformed speculation that vaccine mRNA could alter or integrate into vaccine recipients’ DNA.
It does not. But that didn’t prevent some on social media from spinning that claim into a persistent myth alleging that mRNA vaccines can cause or accelerate cancer growth. Anti-vaccine groups even coined the term “turbo cancer” to describe a fake phenomenon of abnormally aggressive cancers allegedly linked to COVID-19 vaccines.
They used the American Cancer Society’s 2024 cancer projection—based on incidence data through 2020—and a study of global cancer trends between 1999 and 2019 to bolster the false claims. This exposed the dishonesty at the heart of the anti-vaccine messaging, as data that predated the pandemic by decades was carelessly linked to COVID-19 vaccines in viral social media posts.
Some on social media cherry-pick data and use unfounded evidence because the claims that COVID-19 vaccines cause cancer are not true. According to the National Cancer Institute and American Cancer Society, there is no evidence of any link between COVID-19 vaccines and an increase in cancer diagnosis, progression, or remission.
Why does the vaccine cancer myth endure?
At the root of false cancer claims about COVID-19 vaccines is a long history of anti-vaccine figures falsely linking vaccines to cancer. Polio and HPV vaccines have both been the target of disproven cancer myths.
Not only do HPV vaccines not cause cancer, they are one of only two vaccines that prevent cancer.
In the case of polio vaccines, some early batches were contaminated with simian virus 40 (SV40), a virus that is known to cause cancer in some mammals but not humans. The contaminated batches were discovered, and no other vaccine has had SV40 contamination in over 60 years.
Follow-up studies found no increase in cancer rates in people who received the SV40-contaminated polio vaccine. Yet, vaccine opponents have for decades claimed that polio vaccines cause cancer.
Recycling of the SV40 myth
The SV40 myth resurfaced in 2023 when vaccine opponents claimed that COVID-19 vaccines contain the virus. In reality, a small, nonfunctional piece of the SV40 virus is used in the production of some COVID-19 vaccines. This DNA fragment, called the promoter, is commonly used in biomedical research and vaccine development and doesn’t remain in the finished product.
Crucially, the SV40 promoter used to produce COVID-19 vaccines doesn’t contain the part of the virus that enters the cell nucleus and is associated with cancer-causing properties in some animals. The promoter also lacks the ability to survive on its own inside the cell or interact with DNA. In other words, it poses no risk to humans.
Over 5.6 billion people worldwide have received COVID-19 vaccines since December 2020. At that scale, even the tiniest increase in cancer rates in vaccinated populations would equal hundreds of thousands of excess cancer diagnoses and deaths. The evidence for alleged vaccine-linked cancer would be observed in real incidence, treatment, and mortality data, not social media anecdotes or unverifiable reports.

How does the drug abemaciclib treat breast cancer?
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 anti-cancer drug abemaciclib (also known as Vernezio) has this month been added to the Australian Pharmaceutical Benefits Scheme (PBS) to treat certain types of breast cancer.
This significantly reduces the cost of the drug. A patient can now expect to pay A$31.60 for a 28-day supply ($7.70 with a health care concession card). The price of abemaciclib without government subsidy is $4,250.
So what is abemaciclib, and how did we get to this point?
It stops cells dividing
Researchers at the pharmaceutical company Eli Lilly developed abemaciclib and published the first study on the drug (then known as LY2835219) in 2014.
Abemaciclib is a type of drug known as a “cyclin-dependent kinase inhibitor”. It’s taken as a pill twice a day.
To maintain our health, many of the cells in our bodies need to grow and divide to produce new cells. Cancers develop when cells grow and divide out of control. Therefore, stopping cells from dividing into new cells is one way that cancer can be fought.
When cells divide, they have to make a copy of their DNA to pass onto the new cell. “Cyclin-dependent kinases” (CDKs for short) are essential for this process. So, if you stop the CDKs, you stop the DNA copying, you stop cells dividing, and you fight the cancer.
However, there are different types of CDKs, and not all cancers need them all to grow. Abemaciclib specifically targets CDK4 and CDK6. Thankfully, a lot of cancers do need these CDKs, including some breast cancers.
The drug targets CDK4 and CDK6. Photoroyalty/Shutterstock But abemaciclib will only be effective against cancers that rely on CDK4 and CDK6 for continued growth. This specificity also means abemaciclib is fairly unique, so it can’t easily be replaced with a different drug.
Two other CDK4/6 inhibitors were developed around the same time as abemaciclib, and are called ribociclib and palbociclib. Both of these drugs are also on the PBS for specific types of breast cancer. As the drugs differ in their chemical structures, they have slight differences in the way they are taken up and processed by the body. The preferred drug given to a breast cancer patient will depend on their unique circumstances.
What are the side effects?
Research is still ongoing into the differences between each of these CDK4/6 inhibitors, but it is known that the side effects are largely similar, but can differ in severity.
The most common side effects of abemaciclib are fatigue, diarrhoea and neutropenia (reduced white blood cells). The gastrointestinal issues are generally more severe with abemaciclib.
If these side effects are too severe, abemaciclib treatment can be stopped.
What types of cancer has abemaciclib been approved for?
In 2017, the United States Food and Drug Administration (FDA) approved abemaciclib for the treatment of patients with metastatic HR+/HER2- (hormone receptor-positive and human epidermal growth factor receptor 2-negative) breast cancer who did not respond to standard endocrine therapy.
Australia’s Therapeutic Goods Administration (TGA) similarly approved abemaciclib in 2022 as an “adjuvant” therapy (after the initial surgery to remove the tumour) for patients with HR+/HER2- invasive early breast cancer which had spread to lymph nodes and was at high risk of returning.
The drug is approved for people with early breast cancer which is at high risk of returning. PeopleImages.com – Yuri A/Shutterstock As of May 1 2024, the PBS covers this use of abemaciclib in combination with endocrine therapy such as fulvestrant, which is also listed on the PBS. Endocrine therapy, also known as hormonal therapy, blocks hormone receptor positive (HR+) cancers from receiving the hormones they need to survive.
Could abemaciclib be used for other cancers in the future?
Abemaciclib is of great interest to scientists and medical practitioners, and testing is ongoing to assess the effectiveness of abemaciclib in treating a range of other cancers, including gastrointestinal cancers and blood cancers.
Abemaciclib may even be usable in brain cancers, as it has long been known to be capable of crossing the blood-brain barrier, a common stumbling block for potential anti-cancer drugs.
Time will tell whether the role of abemaciclib in health care will be expanded. But for now, its inclusion on the PBS is sure to bring some relief to breast cancer patients nationwide.

Nobody’s Sleeping – by Dr. Bijoy John
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.
Firstly, let’s mention: yes, for the sake of being methodical and comprehensive this book does give the same baseline advice as every other sleep book out there. However, it gives something else, too:
It goes beyond that baseline, to a) give more personalized advice for various demographics (e.g. per age, sex, health conditions, etc) and b) give direction for further personalizing one’s own sleep improvement journey, by troubleshooting and fixing things that may pertain to you very specifically and not to most people.
This means, that if you’re doing “all the right things” but still having sleep-related problems, there is hope and there are more approaches to try.
The style in which this is delivered is very readable, which is good, because if one hasn’t been sleeping well, then chances are that an intellectual challenge would be about as welcome as a physical challenge—that is to say: not at all.
Bottom line: if sleep is not your strength and you would like it to be and all the usual things haven’t yet worked, this book may well help you to overcome the hurdles between you and a good night’s sleep each night.

Chetna’s Healthy Indian – by Chetna Makan
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.
Indian food is wonderful—a subjective opinion perhaps, but a popular view, and one this reviewer certainly shares. And of course, cooking with plenty of vegetables and spices is a great way to get a lot of health benefits.
There are usually downsides though, such as that in a lot of Indian cookbooks, every second thing is deep-fried, and what’s not deep-fried contains an entire day or more’s saturated fat content in ghee, and a lot of sides have more than their fair share of sugar.
This book fixes all that, by offering 80 recipes that prioritize health without sacrificing flavor.
The recipes are, as the title suggests, vegetarian, though many are not vegan (yogurt and cheese featuring in many recipes). That said, even if you are vegan, it’s pretty easy to veganize those with the obvious plant-based substitutions. If you have soy yogurt and can whip up vegan paneer yourself (here’s our own recipe for that), you’re pretty much sorted.
The cookbook strikes a good balance of being neither complicated nor “did we really need a recipe for this?” basic, and delivers value in all of its recipes. The ingredients, often a worry for many Westerners, should be easily found if you have a well-stocked supermarket near you; there’s nothing obscure here.
Bottom line: if you’d like to cook more Indian food and want your food to be exciting without also making your blood pressure exciting, then this is an excellent book for keeping you well-nourished, body and soul.

High-Protein Plant-Based Diet for Beginners – by Maya Howard with Ariel Warren
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.
Seasoned vegans (well-seasoned vegans?) will know that getting enough protein from a plant-based diet is really not the challenge that many think it is, but for those just embarking on cutting out the meat, it’s not useful to say “it’s easy!”; it’s useful to show how.
That’s what this book does. And not just by saying “these foods” and leaving people to wonder if they need to eat a pound of tofu each day to get their protein in. Instead, recipes. Enough for a 4-week meal plan, and the idea is that after a month of eating that way, it won’t be nearly so mysterious.
The recipes are very easy to execute, while still having plenty of flavor (which is what happens when one uses a lot of flavorsome main ingredients and then seasons them well too). The ingredients are not obscure, and you should be able to find everything easily in any medium-sized supermarket.
As for the well-roundedness of the diet, we’ll mention that the “with Ariel Warren” in the by-line means that while the book was principally authored by Maya Howard (who is, at time of writing, a nutritionist-in-training), she had input throughout from Ariel Warren (a Registered Dietician Nutritionist) to ensure she didn’t go off-piste anyway and it gets the professional stamp of approval.
Bottom line: if you’d like to cook plant based while still prioritizing protein and you’re not sure how to make that exciting and fun instead of a chore, then this book will show you how to please your taste buds and improve your body composition at the same time.
