What you need to know
- COVID-19 vaccines do not cause “turbo cancer” or contain SV40, a virus that has been suspected of causing cancer.
- There is no link between rising cancer rates and COVID-19 vaccines.
- Staying up to date on COVID-19 vaccines is a safe, free way to support long-term health.
Myths that COVID-19 vaccines cause cancer have been circulating since the vaccines were first developed. These false claims resurfaced last month after Princess Kate Middleton announced that she is undergoing cancer treatment, with some vaccine opponents falsely claiming Middleton has a “turbo cancer” caused by COVID-19 vaccines.
Here’s what we know: “Turbo cancer” is a made-up term for a fake phenomenon, and there is strong evidence that COVID-19 vaccines do not cause cancer or increase cancer risk.
Read on to learn how to recognize false claims about COVID-19 vaccines and cancer.
Do COVID-19 vaccines contain cancer-causing ingredients?
No. Some vaccine opponents claim that COVID-19 vaccines contain SV40, a virus that has been suspected of causing cancer. This claim is false.
A piece of SV40’s DNA sequence—called a “promoter”—was used as starting material to develop COVID-19 vaccines, but the virus itself is not present in the vaccines. The promoter does not contain the part of the virus that enters the cell nucleus, so it poses no risk.
COVID-19 vaccines and their ingredients have been rigorously studied in millions of people worldwide and have been determined to be safe. The National Cancer Institute and the American Cancer Society agree that COVID-19 vaccines do not increase cancer risk or accelerate cancer growth.
Why are cancer rates rising in the U.S.?
Since the 1990s, cancer rates have been on the rise globally and in the U.S., most notably in people under 50. Increased cancer screening may partially explain the rising number of cancer diagnoses. Exposure to air pollution and lifestyle factors like tobacco use, alcohol use, and diet may also be contributing factors.
What are the benefits of staying up to date on COVID-19 vaccines?
Staying up to date on COVID-19 vaccines is a safe way to protect our long-term health. COVID-19 vaccines prevent severe illness, hospitalization, death, and long COVID.
The CDC says staying up to date on COVID-19 vaccines is a safer and more reliable way to build protection against COVID-19 than getting sick from COVID-19.

The Brain’s Way of Healing – by Dr. Norman Doidge
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.
First, what this book isn’t: any sort of wishy-washy “think yourself better” fluff, and nor is it a “tapping into your Universal Divine Essence” thing.
In contrast, Dr. Norman Doidge sticks with science, and the only “vibrational frequencies” involved are the sort that come from an MRI machine or similar.
The author makes bold claims of the potential for leveraging neuroplasticity to heal many chronic diseases. All of them are neurological in whole or in part, ranging from chronic pain to Parkinson’s.
How well are these claims backed up, you ask?
The book makes heavy use of case studies. In science, case studies rarely prove anything, so much as indicate a potential proof of principle. Clinical trials are what’s needed to become more certain, and for Dr. Doidge’s claims, these are so far sadly lacking, or as yet inconclusive.
Where the book’s strengths lie is in describing exactly what is done, and how, to effect each recovery. Specific exercises to do, and explanations of the mechanism of action. To that end, it makes them very repeatable for any would-be “citizen scientist” who wishes to try (in the cases that they don’t require special equipment).
Bottom line: this book would be more reassuring if its putative techniques had enjoyed more clinical studies… But in the meantime, it’s a fair collection of promising therapeutic approaches for a number of neurological disorders.

I’m feeling run down. Why am I more likely to get sick? And how can I boost my 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.
It has been a long winter, filled with many viruses and cost-of-living pressures, on top of the usual mix of work, study, life admin and caring responsibilities.
Stress is an inevitable part of life. In short bursts, our stress response has evolved as a survival mechanism to help us be more alert in fight or flight situations.
But when stress is chronic, it weakens the immune system and makes us more vulnerable to illnesses such as the common cold, flu and COVID.
Pexels/Ketut Subiyanto Stress makes it harder to fight off viruses
When the immune system starts to break down, a virus that would normally have been under control starts to flourish.
Once you begin to feel sick, the stress response rises, making it harder for the immune system to fight off the disease. You may be sick more often and for longer periods of time, without enough immune cells primed and ready to fight.
In the 1990s, American psychology professor Sheldon Cohen and his colleagues conducted a number of studies where healthy people were exposed to an upper respiratory infection, through drops of virus placed directly into their nose.
These participants were then quarantined in a hotel and monitored closely to determine who became ill.
One of the most important factors predicting who got sick was prolonged psychological stress.
Cortisol suppresses immunity
“Short-term stress” is stress that lasts for a period of minutes to hours, while “chronic stress” persists for several hours per day for weeks or months.
When faced with a perceived threat, psychological or physical, the hypothalamus region of the brain sets off an alarm system. This signals the release of a surge of hormones, including adrenaline and cortisol.
The hypothalamus sets off an alarm system in response to a real or perceived threat. stefan3andrei/Shutterstock In a typical stress response, cortisol levels quickly increase when stress occurs, and then rapidly drop back to normal once the stress has subsided. In the short term, cortisol suppresses inflammation, to ensure the body has enough energy available to respond to an immediate threat.
But in the longer term, chronic stress can be harmful. A Harvard University study from 2022 showed that people suffering from psychological distress in the lead up to their COVID infection had a greater chance of experiencing long COVID. They classified this distress as depression, probable anxiety, perceived stress, worry about COVID and loneliness.
Those suffering distress had close to a 50% greater risk of long COVID compared to other participants. Cortisol has been shown to be high in the most severe cases of COVID.
Stress causes inflammation
Inflammation is a short-term reaction to an injury or infection. It is responsible for trafficking immune cells in your body so the right cells are present in the right locations at the right times and at the right levels.
The immune cells also store a memory of that threat to respond faster and more effectively the next time.
Initially, circulating immune cells detect and flock to the site of infection. Messenger proteins, known as pro-inflammatory cytokines, are released by immune cells, to signal the danger and recruit help, and our immune system responds to neutralise the threat.
During this response to the infection, if the immune system produces too much of these inflammatory chemicals, it can trigger symptoms such as nasal congestion and runny nose.
Our immune response can trigger symptoms such as a runny nose. Alyona Mandrik/Shutterstock What about chronic stress?
Chronic stress causes persistently high cortisol secretion, which remains high even in the absence of an immediate stressor.
The immune system becomes desensitised and unresponsive to this cortisol suppression, increasing low-grade “silent” inflammation and the production of pro-inflammatory cytokines (the messenger proteins).
Immune cells become exhausted and start to malfunction. The body loses the ability to turn down the inflammatory response.
Over time, the immune system changes the way it responds by reprogramming to a “low surveillance mode”. The immune system misses early opportunities to destroy threats, and the process of recovery can take longer.
So how can you manage your stress?
We can actively strengthen our immunity and natural defences by managing our stress levels. Rather than letting stress build up, try to address it early and frequently by:
1) Getting enough sleep
Getting enough sleep reduces cortisol levels and inflammation. During sleep, the immune system releases cytokines, which help fight infections and inflammation.
2) Taking regular exercise
Exercising helps the lymphatic system (which balances bodily fluids as part of the immune system) circulate and allows immune cells to monitor for threats, while sweating flushes toxins. Physical activity also lowers stress hormone levels through the release of positive brain signals.
3) Eating a healthy diet
Ensuring your diet contains enough nutrients – such as the B vitamins, and the full breadth of minerals like magnesium, iron and zinc – during times of stress has a positive impact on overall stress levels. Staying hydrated helps the body to flush out toxins.
4) Socialising and practising meditation or mindfulness
These activities increase endorphins and serotonin, which improve mood and have anti-inflammatory effects. Breathing exercises and meditation stimulate the parasympathetic nervous system, which calms down our stress responses so we can “reset” and reduce cortisol levels.

Longevity… Simplified – by Dr. Howard Luks
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 spirit of the book itself, we’ll keep this one simple:
The information in this book will not be new to regular readers of 10almonds, or at least, not if you’ve been with us for a while (because we can only cover so much per day, so long-time readers will have accumulated more knowledge).
On the other hand, the information is clear, correct, and very much stripped down to the most important basics. Not the very simplest basics, which would be an oversimplification to the point of inutility, but the most important basics.
To take an example, when it comes to exercise, he doesn’t say “exercise more” but rather that “a complete exercise program has four pillars: aerobic training, resistance training, balance training, and high-intensity interval training (HIIT)”, and then he goes about explaining, in clear and simple terms, how to do those.
The style is similar when it comes to diet, sleep, and body-part-specific chapters such as about heart health, brain health, and so forth.
Bottom line: if you’re a long-time 10almonds reader, you probably don’t need this one, but it’d be a great book for someone else who has expressed an interest in getting healthier, as it really is a top-tier “primer” in increasing health and healthspan.

What does it mean to be immunocompromised?
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 immune systems help us fight off disease, but certain health conditions and medications can weaken our immune systems. People whose immune systems don’t work as well as they should are considered immunocompromised.
Read on to learn more about how the immune system works, what causes people to be immunocompromised, and how we can protect ourselves and the immunocompromised people around us from illness.
What is the immune system?
The immune system is a network of cells, organs, and chemicals that helps our bodies fight off infections caused by invaders, such as bacteria, viruses, fungi, and parasites.
Some important parts of the immune system include:
- White blood cells, which attack and kill germs that don’t belong inside our bodies.
- Lymph nodes, which help our bodies filter out germs.
- Antibodies, which help our bodies recognize invaders.
- Cytokines, which tell our immune cells what to do.
What causes people to be immunocompromised?
Some health conditions and medications can prevent our immune systems from functioning optimally, which makes us more vulnerable to infection. Health conditions that compromise the immune system fall into two categories: primary immunodeficiency and secondary immunodeficiency.
Primary immunodeficiency
People with primary immunodeficiency are born with genetic mutations that prevent their immune systems from functioning as they should. There are hundreds of types of primary immunodeficiencies. Since these mutations affect the immune system to varying degrees, some people may experience symptoms and get diagnosed early in life, while others may not know they’re immunocompromised until adulthood.
Secondary immunodeficiency
Secondary immunodeficiency happens later in life due to an infection like HIV, which weakens the immune system over time, or certain types of cancer, which prevent the body from producing enough white blood cells to adequately fight off infection. Studies have also shown that getting infected with COVID-19 may cause immunodeficiency by reducing our production of “killer T-cells,” which help fight off infections.
Sometimes necessary treatments for certain medical conditions can also cause secondary immunodeficiency. For example, people with autoimmune disorders—which cause the immune system to become overactive and attack healthy cells—may need to take immunosuppressant drugs to manage their symptoms. However, the drugs can make them more vulnerable to infection.
People who receive organ transplants may also need to take immunosuppressant medications for life to prevent their body from rejecting the new organ. (Given the risk of infection, scientists continue to research alternative ways for the immune system to tolerate transplantation.)
Chemotherapy for cancer patients can also cause secondary immunodeficiency because it kills the immune system’s white blood cells as it’s trying to kill cancer cells.
What are the symptoms of a compromised immune system?
People who are immunocompromised may become sick more frequently than others or may experience more severe or longer-term symptoms than others who contract the same disease.
Other symptoms of a compromised immune system may include fatigue; digestive problems like cramping, nausea, and diarrhea; and slow wound healing.
How can I find out if I’m immunocompromised?
If you think you may be immunocompromised, talk to your health care provider about your medical history, your symptoms, and any medications you take. Blood tests can determine whether your immune system is producing adequate proteins and cells to fight off infection.
I’m immunocompromised—how can I protect myself from infection?
If you’re immunocompromised, take precautions to protect yourself from illness.
Wash your hands regularly, wear a well-fitting mask around others to protect against respiratory viruses, and ensure that you’re up to date on recommended vaccines.
Immunocompromised people may need more doses of vaccines than people who are not immunocompromised—including COVID-19 vaccines. Talk to your health care provider about which vaccines you need.
How can I protect the immunocompromised people around me?
You never know who may be immunocompromised. The best way to protect immunocompromised people around you is to avoid spreading illnesses.
If you know you’re sick, isolate whenever possible. Wear a well-fitting mask around others—especially if you know that you’re sick or that you’ve been exposed to germs. Make sure you’re up to date on recommended vaccines, and practice regular hand-washing.
If you’re planning to spend time with someone who is immunocompromised, ask them what steps you can take to keep them safe.

Black Bean Burgers With Guacamole
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.
Once again proving that burgers do not have to be unhealthy, this one’s a nutritional powerhouse full of protein, fiber, vitamins, and minerals, as well as healthy fats and extra health-giving spices.
You will need
- 1 can black beans, drained and rinsed (or 1 cup same, cooked, drained, and rinsed)
- 3 oz walnuts (if allergic, substitute with pumpkin seeds)
- 1 tbsp chia seeds
- 1 tbsp flax seeds
- ½ red onion, finely chopped
- 1 small eggplant, diced small (e.g. ½” cubes or smaller)
- 1 small carrot, grated
- 3 tbsp finely chopped cilantro (or if you have the “this tastes like soap” gene, then substitute with parsley)
- 1 tbsp lemon juice
- 1 jalapeño pepper, finely chopped (adjust per heat preferences)
- ¼ bulb garlic, crushed
- 2 tsp black pepper
- 1 tsp smoked paprika
- 1 tsp cayenne pepper (adjust per heat preferences)
- ½ tsp MSG or 1 tsp low-sodium salt
- Burger buns (you can use our Delicious Quinoa Avocado Bread recipe if you like)
For the guacamole:
- 1 large ripe avocado, pitted, skinned, and chopped
- 1 tbsp lime juice
- 1 tomato, finely chopped
- ¼ red onion, finely chopped
- ¼ bulb garlic, crushed
- 1 tsp red chili pepper flakes (adjust per heat preferences)
Method
(we suggest you read everything at least once before doing anything)
1) Process the walnuts, chia seeds, and flax seeds in a food processor/blender, until they become a coarse mixture. Set aside.
2) Heat a little oil in a skillet, and fry the red onion, aubergine, and carrot for 5 minutes stirring frequently, then add the garlic and jalapeño and stir for a further 1 minute. Set aside.
3) Combine both mixtures you set aside with the rest of the ingredients from the burger section of the recipe, except the buns, and process them in the food processor on a low setting if possible, until you have a coarse mixture—you still want some texture, not a paste.
4) Shape into patties; this recipe gives for 4 large patties or 8 small ones. When you’ve done this, put them in the fridge for at least 30 minutes, to firm up.
5) While you wait, make the guacamole by mashing the avocado with the lime juice, and then stirring into the onion, tomato, garlic, and pepper.
6) Cook the patties; you can do this on the grill, in a skillet, or in the oven, per your preference. Grilling or frying should take about 5 minutes on each side, give or take the size and shape of the patties. Baking in the oven should take 20–30 minutes at 400℉ / 200℃ turning over halfway through, but keep an eye on them, because again, the size and shape of the patties will affect this. You may be wondering: aren’t they all going to be patty-shaped? And yes, but for example a wide flat patty will cook more quickly than the same volume of burger mixture in a taller less wide patty.
7) Assemble! We recommend the order: bottom bun, guacamole, burger patty, any additional toppings you want to add (e.g. more salad, pickles, etc), top bun:
Enjoy!

Taking A Trip Through The Evidence On Psychedelics
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 Tuesday’s newsletter, we asked you for your opinions on the medicinal use of psychedelics, and got the above-depicted, below-described, set of responses:
- 32% said “This is a good, evidence-based way to treat many brain disorders”
- 32% said “There are some benefits, but they don’t outweigh the risks”
- 20% said “This can help a select few people only; useless for the majority”
- 16% said “This is hippie hogwash and hearsay; wishful thinking at best”
Quite a spread of answers, so what does the science say?
This is hippie hogwash and hearsay; wishful thinking at best! True or False?
False! We’re tackling this one first, because it’s easiest to answer:
There are some moderately-well established [usually moderate] clinical benefits from some psychedelics for some people.
If that sounds like a very guarded statement, it is. Part of this is because “psychedelics” is an umbrella term; perhaps we should have conducted separate polls for psilocybin, MDMA, ayahuasca, LSD, ibogaine, etc, etc.
In fact: maybe we will do separate main features for some of these, as there is a lot to say about each of them separately.
Nevertheless, looking at the spread of research as it stands for psychedelics as a category, the answers are often similar across the board, even when the benefits/risks may differ from drug to drug.
To speak in broad terms, if we were to make a research summary for each drug it would look approximately like this in each case:
- there has been research into this, but not nearly enough, as “the war on drugs” may well have manifestly been lost (the winner of the war being: drugs; still around and more plentiful than ever), but it did really cramp science for a few decades.
- the studies are often small, heterogenous (often using moderately wealthy white student-age population samples), and with a low standard of evidence (i.e. the methodology often has some holes that leave room for reasonable doubt).
- the benefits recorded are often small and transient.
- in their favor, though, the risks are also generally recorded as being quite low, assuming proper safe administration*.
*Illustrative example:
Person A takes MDMA in a club, dances their cares away, has had only alcohol to drink, sweats buckets but they don’t care because they love everyone and they see how we’re all one really and it all makes sense to them and then they pass out from heat exhaustion and dehydration and suffer kidney damage (not to mention a head injury when falling) and are hospitalized and could die;
Person B takes MDMA in a lab, is overwhelmed with a sense of joy and the clarity of how their participation in the study is helping humanity; they want to hug the researcher and express their gratitude; the researcher reminds them to drink some water.
Which is not to say that a lab is the only safe manner of administration; there are many possible setups for supervised usage sites. But it does mean that the risks are often as much environmental as they are risks inherent to the drug itself.
Others are more inherent to the drug itself, such as adverse cardiac events for some drugs (ibogaine is one that definitely needs medical supervision, for example).
For those who’d like to see numbers and clinical examples of the bullet points we gave above, here you go; this is a great (and very readable) overview:
NIH | Evidence Brief: Psychedelic Medications for Mental Health and Substance Use Disorders
Notwithstanding the word “brief” (intended in the sense of: briefing), this is not especially brief and is rather an entire book (available for free, right there!), but we do recommend reading it if you have time.
This can help a select few people only; useless for the majority: True or False?
True, technically, insofar as the evidence points to these drugs being useful for such things as depression, anxiety, PTSD, addiction, etc, and estimates of people who struggle with mental health issues in general is often cited as being 1 in 4, or 1 in 5. Of course, many people may just have moderate anxiety, or a transient period of depression, etc; many, meanwhile, have it worth.
In short: there is a very large minority of people who suffer from mental health issues that, for each issue, there may be one or more psychedelic that could help.
This is a good, evidence-based way to treat many brain disorders: True or False?
True if and only if we’re willing to accept the so far weak evidence that we discussed above. False otherwise, while the jury remains out.
One thing in its favor though is that while the evidence is weak, it’s not contradictory, insofar as the large preponderance of evidence says such therapies probably do work (there aren’t many studies that returned negative results); the evidence is just weak.
When a thousand scientists say “we’re not completely sure, but this looks like it helps; we need to do more research”, then it’s good to believe them on all counts—the positivity and the uncertainty.
This is a very different picture than we saw when looking at, say, ear candling or homeopathy (things that the evidence says simply do not work).
We haven’t been linking individual studies so far, because that book we linked above has many, and the number of studies we’d have to list would be:
n = number of kinds of psychedelic drugs x number of conditions to be treated
e.g. how does psilocybin fare for depression, eating disorders, anxiety, addiction, PTSD, this, that, the other; now how does ayahuasca fare for each of those, and so on for each drug and condition; at least 25 or 30 as a baseline number, and we don’t have that room.
But here are a few samples to finish up:
- Psilocybin as a New Approach to Treat Depression and Anxiety in the Context of Life-Threatening Diseases—A Systematic Review and Meta-Analysis of Clinical Trials
- Therapeutic Use of LSD in Psychiatry: A Systematic Review of Randomized-Controlled Clinical Trials
- Efficacy of Psychoactive Drugs for the Treatment of Posttraumatic Stress Disorder: A Systematic Review of MDMA, Ketamine, LSD and Psilocybin
- Changes in self-rumination and self-compassion mediate the effect of psychedelic experiences on decreases in depression, anxiety, and stress.
- Psychedelic Treatments for Psychiatric Disorders: A Systematic Review and Thematic Synthesis of Patient Experiences in Qualitative Studies
- Repeated lysergic acid diethylamide (LSD) reverses stress-induced anxiety-like behavior, cortical synaptogenesis deficits and serotonergic neurotransmission decline
In closing…
The general scientific consensus is presently “many of those drugs may ameliorate many of those conditions, but we need a lot more research before we can say for sure”.
On a practical level, an important take-away from this is twofold:
- drugs, even those popularly considered recreational, aren’t ontologically evil, generally do have putative merits, and have been subject to a lot of dramatization/sensationalization, especially by the US government in its famous war on drugs.
- drugs, even those popularly considered beneficial and potentially lifechangingly good, are still capable of doing great harm if mismanaged, so if putting aside “don’t do drugs” as a propaganda of the past, then please do still hold onto “don’t do drugs alone”; trained professional supervision is a must for safety.
Take care!
