Dr. LeGrand Peterson wants us to get the most out of our supplements, so watch out for these…
Time to split up some pairs…
In most cases these are a matter of competing for absorption; sometimes to the detriment of both, sometimes to the detriment of one or the other, and sometimes, the problem is entirely different and they just interact in a way that could potentially cause other problems. Dr. Peterson advises as follows:
- Vitamin C and vitamin B12: taking these together can reduce the absorption of Vitamin B12, as vitamin C can overpower it.
- Vitamin C and copper: high amounts of vitamin C can decrease copper absorption, especially in those who are severely copper deficient.
- Magnesium and calcium: these two minerals compete for absorption in the intestines, potentially reducing the effectiveness of both.
- Calcium and iron: calcium can decrease iron absorption, so they should not be taken together, especially if you are iron deficient.
- Calcium and zinc: calcium also competes with zinc, reducing zinc absorption; they should be taken at different times.
- Zinc and copper: zinc and copper compete for absorption, so they should be taken at separate times.
- Iron and zinc: iron can decrease zinc absorption, and thus, they should not be taken together.
- Iron and green tea: perhaps a surprising one, but green tea can reduce iron absorption, so they should not be taken simultaneously.
- Vitamin E and vitamin K: vitamin E increases bleeding risk, while vitamin K promotes clotting, making them opposites and risky to take together.
- Fish oil and ginkgo biloba: both are anticoagulants and can increase the risk of bleeding, especially if taken with blood thinners like warfarin.
If you need to take supplements that compete (or conflict or otherwise potentially adversely interact) with each other, it’s recommended to separate them by at least 4 hours, or better yet, take one in the morning and the other at night. If in doubt, do speak with your pharmacist or doctor for personalized advice
You may be thinking: half my foods contain half of these nutrients! And yes, assuming you have a nutritionally dense diet, this is probably the case. Foods typically release nutrients more slowly than supplements, and unlike supplements, do not usually contain megadoses (although they can, such as the selenium content of Brazil nuts, or vitamin A in carrots). Basically, food is in most cases safer and gentler than supplements. If concerned, do speak with your nutritionist or doctor for personalized advice.

America’s Health System Isn’t Ready for the Surge of Seniors With Disabilities
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 number of older adults with disabilities — difficulty with walking, seeing, hearing, memory, cognition, or performing daily tasks such as bathing or using the bathroom — will soar in the decades ahead, as baby boomers enter their 70s, 80s, and 90s.
But the health care system isn’t ready to address their needs.
That became painfully obvious during the covid-19 pandemic, when older adults with disabilities had trouble getting treatments and hundreds of thousands died. Now, the Department of Health and Human Services and the National Institutes of Health are targeting some failures that led to those problems.
One initiative strengthens access to medical treatments, equipment, and web-based programs for people with disabilities. The other recognizes that people with disabilities, including older adults, are a separate population with special health concerns that need more research and attention.
Lisa Iezzoni, 69, a professor at Harvard Medical School who has lived with multiple sclerosis since her early 20s and is widely considered the godmother of research on disability, called the developments “an important attempt to make health care more equitable for people with disabilities.”
“For too long, medical providers have failed to address change in society, changes in technology, and changes in the kind of assistance that people need,” she said.
Among Iezzoni’s notable findings published in recent years:
Most doctors are biased. In survey results published in 2021, 82% of physicians admitted they believed people with significant disabilities have a worse quality of life than those without impairments. Only 57% said they welcomed disabled patients.
“It’s shocking that so many physicians say they don’t want to care for these patients,” said Eric Campbell, a co-author of the study and professor of medicine at the University of Colorado.
While the findings apply to disabled people of all ages, a larger proportion of older adults live with disabilities than younger age groups. About one-third of people 65 and older — nearly 19 million seniors — have a disability, according to the Institute on Disability at the University of New Hampshire.
Doctors don’t understand their responsibilities. In 2022, Iezzoni, Campbell, and colleagues reported that 36% of physicians had little to no knowledge of their responsibilities under the 1990 Americans With Disabilities Act, indicating a concerning lack of training. The ADA requires medical practices to provide equal access to people with disabilities and accommodate disability-related needs.
Among the practical consequences: Few clinics have height-adjustable tables or mechanical lifts that enable people who are frail or use wheelchairs to receive thorough medical examinations. Only a small number have scales to weigh patients in wheelchairs. And most diagnostic imaging equipment can’t be used by people with serious mobility limitations.
Iezzoni has experienced these issues directly. She relies on a wheelchair and can’t transfer to a fixed-height exam table. She told me she hasn’t been weighed in years.
Among the medical consequences: People with disabilities receive less preventive care and suffer from poorer health than other people, as well as more coexisting medical conditions. Physicians too often rely on incomplete information in making recommendations. There are more barriers to treatment and patients are less satisfied with the care they do get.
Egregiously, during the pandemic, when crisis standards of care were developed, people with disabilities and older adults were deemed low priorities. These standards were meant to ration care, when necessary, given shortages of respirators and other potentially lifesaving interventions.
There’s no starker example of the deleterious confluence of bias against seniors and people with disabilities. Unfortunately, older adults with disabilities routinely encounter these twinned types of discrimination when seeking medical care.
Such discrimination would be explicitly banned under a rule proposed by HHS in September. For the first time in 50 years, it would update Section 504 of the Rehabilitation Act of 1973, a landmark statute that helped establish civil rights for people with disabilities.
The new rule sets specific, enforceable standards for accessible equipment, including exam tables, scales, and diagnostic equipment. And it requires that electronic medical records, medical apps, and websites be made usable for people with various impairments and prohibits treatment policies based on stereotypes about people with disabilities, such as covid-era crisis standards of care.
“This will make a really big difference to disabled people of all ages, especially older adults,” said Alison Barkoff, who heads the HHS Administration for Community Living. She expects the rule to be finalized this year, with provisions related to medical equipment going into effect in 2026. Medical providers will bear extra costs associated with compliance.
Also in September, NIH designated people with disabilities as a population with health disparities that deserves further attention. This makes a new funding stream available and “should spur data collection that allows us to look with greater precision at the barriers and structural issues that have held people with disabilities back,” said Bonnielin Swenor, director of the Johns Hopkins University Disability Health Research Center.
One important barrier for older adults: Unlike younger adults with disabilities, many seniors with impairments don’t identify themselves as disabled.
“Before my mom died in October 2019, she became blind from macular degeneration and deaf from hereditary hearing loss. But she would never say she was disabled,” Iezzoni said.
Similarly, older adults who can’t walk after a stroke or because of severe osteoarthritis generally think of themselves as having a medical condition, not a disability.
Meanwhile, seniors haven’t been well integrated into the disability rights movement, which has been led by young and middle-aged adults. They typically don’t join disability-oriented communities that offer support from people with similar experiences. And they don’t ask for accommodations they might be entitled to under the ADA or the 1973 Rehabilitation Act.
Many seniors don’t even realize they have rights under these laws, Swenor said. “We need to think more inclusively about people with disabilities and ensure that older adults are fully included at this really important moment of change.”

Stay off My Operating Table – by Dr. Philip Ovadia
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.
With heart disease as the #1 killer worldwide, and 88% of adults being metabolically unhealthy (leading cause of heart disease), this is serious!
Rather than taking a “quick fix” advise-and-go approach, Dr. Ovadia puts the knowledge and tools in our hands to do better in the long term.
As a heart surgeon himself, his motto here is:
❝What foods to put on your table so you don’t end up on mine❞
There’s a lot more to this book than the simple “eat the Mediterranean diet”:
- While the Mediterranean diet is generally considered the top choice for heart health, he also advises on how to eat healthily on all manner of diets… Carnivore, Keto, Paleo, Atkins, Gluten-Free, Vegan, you-name-it.
- A lot of the book is given to clearing up common misconceptions, things that sounded plausible but are just plain dangerous. This information alone is worth the price of the book, we think.
- There’s also a section given over to explaining the markers of metabolic health, so you can monitor yourself effectively
- Rather than one-size-fits-all, he also talks about common health conditions and medications that may change what you need to be doing
- He also offers advice about navigating the health system to get what you need—including dealing with unhelpful doctors!
Bottom line: A very comprehensive (yet readable!) manual of heart health.

Why a common asthma drug will now carry extra safety warnings about depression
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.
Australia’s Therapeutic Goods Administration (TGA) recently issued a safety alert requiring extra warnings to be included with the asthma and hay fever drug montelukast.
The warnings are for users and their families to look for signs of serious behaviour and mood-related changes, such as suicidal thoughts and depression. The new warnings need to be printed at the start of information leaflets given to both patients and health-care providers (sometimes called a “boxed” warning).
So why did the TGA issue this warning? And is there cause for concern if you or a family member uses montelukast? Here’s what you need to know.
First, what is montelukast?
Montelukast is a prescription drug also known by its brand names which include Asthakast, Lukafast, Montelair and Singulair. It’s used to manage the symptoms of mild-to-moderate asthma and seasonal hay fever in children and adults.
Asthma occurs when the airways tighten and produce extra mucus, which makes it difficult to get air into the lungs. Likewise, the runny nose characteristic of hay fever occurs due to the overproduction of mucus.
Leukotrienes are an important family of chemicals found throughout the airways and involved in both mucus production and airway constriction. Montelukast is a cysteinyl leukotriene receptor antagonist, meaning it blocks the site in the airways where the leukotrienes work.
Montelukast can’t be used to treat acute asthma (an asthma attack), as it takes time for the tablet to be broken down in the stomach and for it to be absorbed into the body. Rather, it’s taken daily to help prevent asthma symptoms or seasonal hay fever.
It can be used alongside asthma puffers that contain corticosteriods and drugs like salbutamol (Ventolin) in the event of acute attacks.
What is the link to depression and suicide?
The possibility that this drug may cause behavioural changes is not new information. Manufacturers knew this as early as 2007 and issued warnings for possible side-effects including depression, suicidality and anxiousness.
The United Kingdom’s Medicines and Healthcare products Regulatory Agency has required a warning since 2008 but mandated a more detailed warning in 2019. The United States’ Food and Drug Administration has required boxed warnings for the drug since 2020.
Montelukast can help children and adults with asthma. adriaticfoto/Shutterstock Montelukast is known to potentially induce a number of behaviour and mood changes, including agitation, anxiety, depression, irritability, obsessive-compulsive symptoms, and suicidal thoughts and actions.
Initially a 2009 study that analysed data from 157 clinical trials involving more than 20,000 patients concluded there were no completed suicides due to taking the drug, and only a rare risk of suicide thoughts or attempts.
The most recent study, published in November 2024, examined data from more than 100,000 children aged 3–17 with asthma or hay fever who either took montelukast or used only inhaled corticosteroids.
It found montelukast use was associated with a 32% higher incidence of behavioural changes. The behaviour change with the strongest association was sleep disturbance, but montelukast use was also linked to increases in anxiety and mood disorders.
In the past ten years, around 200 incidences of behavioural side-effects have been reported to the TGA in connection with montelukast. This includes 57 cases of depression, 60 cases of suicidal thoughts and 17 suicide attempts or incidents of intentional self-injury. There were seven cases where patients taking the drug did complete a suicide.
This is of course tragic. But these numbers need to be seen in the context of the number of people taking the drug. Over the same time period, more than 200,000 scripts for montelukast have been filled under the Pharmaceutical Benefits Scheme.
Overall, we don’t know conclusively that montelukast causes depression and suicide, just that it seems to increase the risk for some people.
We’re still not sure how the drug can act on the brain to lead to behaviour changes. Elif Bayraktar/Shutterstock And if it does change behaviour, we don’t fully understand how this happens. One hypothesis is that the drug and its breakdown products (or metabolites) affect brain chemistry.
Specifically, it might interfere with how the brain detoxifies the antioxidant glutathione or alter the regulation of other brain chemicals, such as neurotransmitters.
Why is the TGA making this change now?
The new risk warning requirement comes from a meeting of the Australian Advisory Committee on Medicines where they were asked to provide advice on ways to minimise the risk for the drug given current international recommendations.
Even though the 2024 review didn’t highlight any new risks, to align with international recommendations, and help address consumer concerns, the advisory committee recommended a boxed warning be added to drug information sheets.
If you have asthma and take montelukast (or your child does), you should not just stop taking the drug, because this could put you at risk of an attack that could be life threatening. If you’re concerned, speak to your doctor who can discuss the risks and benefits of the medication for you, and, if appropriate, prescribe a different medication.

Why do disinfectants only kill 99.9% of germs? Here’s the science
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.
Have you ever wondered why most disinfectants indicate they kill 99.9% or 99.99% of germs, but never promise to wipe out all of them? Perhaps the thought has crossed your mind mid-way through cleaning your kitchen or bathroom.
Surely, in a world where science is able to do all sorts of amazing things, someone would have invented a disinfectant that is 100% effective?
The answer to this conundrum requires understanding a bit of microbiology and a bit of mathematics.
Davor Geber/Shutterstock What is a disinfectant?
A disinfectant is a substance used to kill or inactivate bacteria, viruses and other microbes on inanimate objects.
There are literally millions of microbes on surfaces and objects in our domestic environment. While most microbes are not harmful (and some are even good for us) a small proportion can make us sick.
Although disinfection can include physical interventions such as heat treatment or the use of UV light, typically when we think of disinfectants we are referring to the use of chemicals to kill microbes on surfaces or objects.
Chemical disinfectants often contain active ingredients such as alcohols, chlorine compounds and hydrogen peroxide which can target vital components of different microbes to kill them.
Diseinfectants can contain a range of ingredients. Maridav/Shutterstock The maths of microbial elimination
In the past few years we’ve all become familiar with the concept of exponential growth in the context of the spread of COVID cases.
This is where numbers grow at an ever-accelerating rate, which can lead to an explosion in the size of something very quickly. For example, if a colony of 100 bacteria doubles every hour, in 24 hours’ time the population of bacteria would be more than 1.5 billion.
Conversely, the killing or inactivating of microbes follows a logarithmic decay pattern, which is essentially the opposite of exponential growth. Here, while the number of microbes decreases over time, the rate of death becomes slower as the number of microbes becomes smaller.
For example, if a particular disinfectant kills 90% of bacteria every minute, after one minute, only 10% of the original bacteria will remain. After the next minute, 10% of that remaining 10% (or 1% of the original amount) will remain, and so on.
Because of this logarithmic decay pattern, it’s not possible to ever claim you can kill 100% of any microbial population. You can only ever scientifically say that you are able to reduce the microbial load by a proportion of the initial population. This is why most disinfectants sold for domestic use indicate they kill 99.9% of germs.
Other products such as hand sanitisers and disinfectant wipes, which also often purport to kill 99.9% of germs, follow the same principle.
You might have noticed none of the cleaning products in your laundry cupboard kill 100% of germs. Africa Studio/Shutterstock Real-world implications
As with a lot of science, things get a bit more complicated in the real world than they are in the laboratory. There are a number of other factors to consider when assessing how well a disinfectant is likely to remove microbes from a surface.
One of these factors is the size of the initial microbial population that you’re trying to get rid of. That is, the more contaminated a surface is, the harder the disinfectant needs to work to eliminate the microbes.
If for example you were to start off with only 100 microbes on a surface or object, and you removed 99.9% of these using a disinfectant, you could have a lot of confidence that you have effectively removed all the microbes from that surface or object (called sterilisation).
In contrast, if you have a large initial microbial population of hundreds of millions or billions of microbes contaminating a surface, even reducing the microbial load by 99.9% may still mean there are potentially millions of microbes remaining on the surface.
Time is is a key factor that determines how effectively microbes are killed. So exposing a highly contaminated surface to disinfectant for a longer period is one way to ensure you kill more of the microbial population.
This is why if you look closely at the labels of many common household disinfectants, they will often suggest that to disinfect you should apply the product then wait a specified time before wiping clean. So always consult the label on the product you’re using.
Disinfectants won’t necessarily work in your kitchen exactly like they work in a lab. Ground Picture/Shutterstock Other factors such as temperature, humidity and the type of surface also influence how well a disinfectant works outside the lab.
Similarly, microbes in the real world may be either more or less sensitive to disinfection than those used for testing in the lab.
Disinfectants are one part infection control
The sensible use of disinfectants plays an important role in our daily lives in reducing our exposure to pathogens (microbes that cause illness). They can therefore reduce our chances of getting sick.
The fact disinfectants can’t be shown to be 100% effective from a scientific perspective in no way detracts from their importance in infection control. But their use should always be complemented by other infection control practices, such as hand washing, to reduce the risk of infection.

From Tofu to Salmon
This video (below) by SweetPotatoSoul isn’t just a recipe tutorial; it’s an inspiring journey into the world of vegan cooking, proving that reducing animal products doesn’t have to mean sacrificing flavor.
The key to her vegan salmon is the tofu. However, there’s a trick to the tofu – you have to press it.
Essentially, this involved putting some paper towel on either side of the tofu, and then placing a heavy object on top; this removes excess water and, more importantly, primes the tofu to absorb the flavor of your marinade!
(You’ll want to press the tofu for around 1 hour)
Find the rest of the recipe in the 12-minute video below!
Other Plant-Based Recipes
With there being so many benefits of cutting meat out of your diet, we’ve spent the time reviewing some of the top books on vegan recipes, including The Green Roasting Tin and The Vegan Instant Pot Cookbook. We hope you enjoy them as much as you’ll enjoy this recipe:

How To Recover Quickly From A Stomach Bug
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.
How To Recover Quickly From A Stomach Bug
Is it norovirus, or did you just eat something questionable? We’re not doctors, let alone your doctors, and certainly will not try to diagnose from afar. And as ever, if unsure and/or symptoms don’t go away or do get worse, seek professional medical advice.
That out of the way, we can give some very good general-purpose tips for this one…
Help your immune system to help you
So far as you can, you want a happy healthy immune system. For the most part, we’d recommend the following things:
Beyond Supplements: The Real Immune-Boosters!
…but you probably don’t want to be exercising with a stomach bug, so perhaps sit that one out. Exercise is the preventative; what you need right now is rest.
Hydrate—but watch out
Hydration is critical for recovery especially if you have diarrhea, but drinking too much water too quickly will just make things worse. Great options for getting good hydration more slowly are:
- Peppermint tea
- (peppermint also has digestion-settling properties)
- Ginger tea
- See also: Ginger Does A Lot More Than You Think
- Broths
- These will also help replenish your sodium and other nutrients, gently. Chicken soup for your stomach, and all that. A great plant-based option is sweetcorn soup.
- By broths, we mean clear(ish) water-based soups. This is definitely not the time for creamier soups.
❝Milk and dairy products should be avoided for 24 to 48 hours as they can make diarrhea worse.
Initial dietary choices when refeeding should begin with soups and broth.❞
Source: American College of Gastroenterology
Other things to avoid
Caffeine stimulates the digestion in a way that can make things worse.
Fat is more difficult to digest, and should also be avoided until feeling better.
To medicate or not to medicate?
Loperamide (also known by the brand name Imodium) is generally safe when used as directed.
Click here to see its uses, dosage, side effects, and contraindications
Antibiotics may be necessary for certain microbial infections, but should not be anyone’s first-choice treatment unless advised otherwise by your doctor/pharmacist.
Note that if your stomach bug is not something that requires antibiotics, then taking antibiotics can actually make it worse as the antibiotics wipe out your gut bacteria that were busy helping fight whatever’s going wrong in there:
- Facing a new challenge: the adverse effects of antibiotics on gut microbiota and host immunity
- Antibiotics as major disruptors of gut microbiota
- Microbiotoxicity: antibiotic usage and its unintended harm to the microbiome
A gentler helper
If you want to give your “good bacteria” a hand while giving pathogens a harder time of it, then a much safer home remedy is a little (seriously, do not over do it; we are talking 1–2 tablespoons, or around 20ml) apple cider vinegar, taken diluted in a glass of water.
❝Several studies indicate apple cider vinegar (ACV)’s usefulness in lowering postprandial glycemic response, specifically by slowing of gastric motility❞
(Slowing gastric motility is usually exactly what you want in the case of a stomach bug, and apple cider vinegar)
