Pneumonia: What We Can & Can’t Do About It
Pneumonia is a significant killer of persons over the age of 65, with the risk increasing with age after that, rising very sharply around the age of 85:
While pneumonia is treatable, especially in young healthy adults, the risks get more severe in the older age brackets, and it’s often the case that someone goes into hospital with one thing, then develops pneumonia, which the person was already not in good physical shape to fight, because of whatever hospitalized them in the first place:

Other risk factors besides age
There are a lot of things that can increase our risk factor for pneumonia; they mainly fall into the following categories:
- Autoimmune diseases
- Other diseases of the immune system (e.g. HIV)
- Medication-mediated immunosuppression (e.g. after an organ transplant)
- Chronic lung diseases (e.g. asthma, COPD, Long Covid, emphysema, etc)
- Other serious health conditions ← we know this one’s broad, but it encompasses such things as diabetes, heart disease, and cancer

Things we can do about it
When it comes to risks, we can’t do much about our age and some of the other above factors, but there are other things we can do to reduce our risk, including:
- Get vaccinated against pneumonia if you are over 65 and/or have one of the aforementioned risk factors. This is not perfect (it only reduces the risk for certain kinds of infection) and may not be advisable for everyone (like most vaccines, it can put the body through its paces a bit after taking it), so speak with your own doctor about this, of course.
- See also: Vaccine Mythbusting
- Avoid contagion. While pneumonia itself is not spread person-to-person, it is caused by bacteria or viruses (there are numerous kinds) that are opportunistic and often become a secondary infection when the immune system is already busy with the first one. So, if possible avoid being in confined spaces with many people, and do wash your hands regularly (as a lot of germs are transferred that way and can get into the respiratory tract because you touched your face or such).
- See also: The Truth About Handwashing
- If you have a cold, or flu, or other respiratory infection, take it seriously, rest well, drink fluids, get good immune-boosting nutrients. There’s no such thing as “just a cold”; not anymore.
- Look after your general health too—health doesn’t exist in a vacuum, and nor does disease. Every part of us affects every other part of us, so anything that can be in good order, you want to be in good order.
This last one, by the way? It’s an important reminder that while some diseases (such as some of the respiratory infections that can precede pneumonia) are seasonal, good health isn’t.
We need to take care of our health as best we can every day along the way, because we never know when something could change.

Plum vs Nectarine – 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 plums to nectarines, we picked the nectarines.
Why?
Both are great! But nectarines win at least marginally in each category we look at.
In terms of macros, plums have more carbs while nectarines have more fiber, resulting of course in a lower glycemic index. Plums do have a low GI also; just, nectarines have it better.
When it comes to vitamins, plums have more of vitamins A, B6, C, and K, while nectarines have more of vitamins B1, B2, B3, B5, E, and choline.
In the category of minerals, plums are great but not higher in any mineral than nectarines; nectarines meanwhile have more copper, iron, magnesium, manganese, phosphorus, potassium, and zinc.
All in all, enjoy both. And if having dried fruit, then prunes (dried plums) are generally more widely available than dried nectarines. But if you’re choosing one fruit or the other, nectarine is the way to go.

How Emotions Are Made – by Dr. Lisa Feldman Barrett
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.
We’ve previously reviewed Dr. Barrett’s (also good) book Seven And A Half Lessons About The Brain, and this one is very different, and of more practical use:
The main thrust of the book is: the bioessentialist model of emotions is flawed; there is also no Platonic perfect form of any given emotion, and in fact emotions are constructed by the brain as a learned adaptive response.
She argues this from the dual vectors of on the one hand hard sciences of affective neuroscience and clinical psychology, and on the other hand sociology and anthropology.
In the category of criticism: Dr. Barrett, a very well-known and well-respected cognitive neuroscientist, is not an expert on sociology and anthropology, and some of her claims there are verifiably false.
However, most of the book is given over the psychophysiology, which is entirely her thing, and she explains it clearly and simply while backing everything up with mountains of data.
The usefulness of this book is chiefly: if we understand that emotions are not innate and are instead constructed adaptive (and sometimes maladaptive) neurological responses to stimuli and associations, we can set about rewiring things a little in accord with what’s actually more beneficial to us. The book also outlines how.
Bottom line: if you’d like to be able to not merely manage emotions as they are, but also prune and/or grow them from the stem up, then this book provides a robustly scientific approach for doing that.

Kate Middleton is having ‘preventive chemotherapy’ for cancer. What does this mean?
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.
Catherine, Princess of Wales, is undergoing treatment for cancer. In a video thanking followers for their messages of support after her major abdominal surgery, the Princess of Wales explained, “tests after the operation found cancer had been present.”
“My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment,” she said in the two-minute video.
No further details have been released about the Princess of Wales’ treatment.
But many have been asking what preventive chemotherapy is and how effective it can be. Here’s what we know about this type of treatment.
It’s not the same as preventing cancer
To prevent cancer developing, lifestyle changes such as diet, exercise and sun protection are recommended.
Tamoxifen, a hormone therapy drug can be used to reduce the risk of cancer for some patients at high risk of breast cancer.
Aspirin can also be used for those at high risk of bowel and other cancers.
How can chemotherapy be used as preventive therapy?
In terms of treating cancer, prevention refers to giving chemotherapy after the cancer has been removed, to prevent the cancer from returning.
If a cancer is localised (limited to a certain part of the body) with no evidence on scans of it spreading to distant sites, local treatments such as surgery or radiotherapy can remove all of the cancer.
If, however, cancer is first detected after it has spread to distant parts of the body at diagnosis, clinicians use treatments such as chemotherapy (anti-cancer drugs), hormones or immunotherapy, which circulate around the body .
The other use for chemotherapy is to add it before or after surgery or radiotherapy, to prevent the primary cancer coming back. The surgery may have cured the cancer. However, in some cases, undetectable microscopic cells may have spread into the bloodstream to distant sites. This will result in the cancer returning, months or years later.
With some cancers, treatment with chemotherapy, given before or after the local surgery or radiotherapy, can kill those cells and prevent the cancer coming back.
If we can’t see these cells, how do we know that giving additional chemotherapy to prevent recurrence is effective? We’ve learnt this from clinical trials. Researchers have compared patients who had surgery only with those whose surgery was followed by additional (or often called adjuvant) chemotherapy. The additional therapy resulted in patients not relapsing and surviving longer.
How effective is preventive therapy?
The effectiveness of preventive therapy depends on the type of cancer and the type of chemotherapy.
Let’s consider the common example of bowel cancer, which is at high risk of returning after surgery because of its size or spread to local lymph glands. The first chemotherapy tested improved survival by 15%. With more intense chemotherapy, the chance of surviving six years is approaching 80%.
Preventive chemotherapy is usually given for three to six months.
How does chemotherapy work?
Many of the chemotherapy drugs stop cancer cells dividing by disrupting the DNA (genetic material) in the centre of the cells. To improve efficacy, drugs which work at different sites in the cell are given in combinations.
Chemotherapy is not selective for cancer cells. It kills any dividing cells.
But cancers consist of a higher proportion of dividing cells than the normal body cells. A greater proportion of the cancer is killed with each course of chemotherapy.
Normal cells can recover between courses, which are usually given three to four weeks apart.
What are the side effects?
The side effects of chemotherapy are usually reversible and are seen in parts of the body where there is normally a high turnover of cells.
The production of blood cells, for example, is temporarily disrupted. When your white blood cell count is low, there is an increased risk of infection.
Cell death in the lining of the gut leads to mouth ulcers, nausea and vomiting and bowel disturbance.
Certain drugs sometimes given during chemotherapy can attack other organs, such as causing numbness in the hands and feet.
There are also generalised symptoms such as fatigue.
Given that preventive chemotherapy given after surgery starts when there is no evidence of any cancer remaining after local surgery, patients can usually resume normal activities within weeks of completing the courses of chemotherapy.

Mung Beans vs Red Lentils – 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 mung beans to red lentils, we picked the lentils.
Why?
Both are great! But the lentils win on overall nutritional density.
In terms of macros, they have approximately the same carbs and fiber, and are both low glycemic index foods. The deciding factor is that the lentils have slightly more protein—but it’s not a huge difference; both are very good sources of protein.
In the category of vitamins, mung beans have more of vitamins A, E, and K, while red lentils have more of vitamins B1, B2, B3, B5, B6, B9, C, and choline. An easy win for lentils.
When it comes to minerals, again both are great, but mung beans have more calcium and magnesium (hence the green color) while red lentils have more copper, iron, manganese, phosphorus, potassium, selenium, and zinc. Another clear win for lentils.
Polyphenols are also a worthy category to note here; both have plenty, but red lentils have more, especially flavonols, anthocyanidins, proanthocyanidins, and anthocyanins (whence the red color).
In short: enjoy both, because diversity is almost always best. But if you’re picking one, red lentils are the most nutritious of the two.

PCOS Repair Protocol – by Tamika Woods
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.
PCOS (Polycystic Ovary Syndrome) affects about 1 in 5 women, and the general position of the medical establishment is “Oh dear, how sad; never mind”.
…which leaves a lot of people suffering with symptoms with little to no help.
This book looks to address that, and while it doesn’t claim to cure PCOS, it offers a system for managing (including: reducing) the symptoms. The author, a clinical nutritionist by academic background, tackles this in large part via being mindful about what one eats, in the context of the gut and endocrine system specifically.
It’s not just “have a gut healthy diet and eat foods with these nutrients”, though (although yes: also that). Rather, the author walks us through in-depth quizzes and lab testing advice, to advise the reader on how to understand the root cause of your PCOS symptoms, and then address each of those with an individualized management plan.
The style is on the low-end of pop-science, notwithstanding the clinically-informed content. For those who like a very chatty informal approach, you’ll find this one perfect. For those who don’t, well, you won’t find this one perfect, but you will most likely find it informative all the same.
Bottom line: if you or someone you care about (do you know 5 women?) has PCOS, the information in here could make a difference.

‘I keep away from people’ – combined vision and hearing loss is isolating more and more older Australians
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 ageing population brings a growing crisis: people over 65 are at greater risk of dual sensory impairment (also known as “deafblindness” or combined vision and hearing loss).
Some 66% of people over 60 have hearing loss and 33% of older Australians have low vision. Estimates suggest more than a quarter of Australians over 80 are living with dual sensory impairment.
Combined vision and hearing loss describes any degree of sight and hearing loss, so neither sense can compensate for the other. Dual sensory impairment can occur at any point in life but is increasingly common as people get older.
The experience can make older people feel isolated and unable to participate in important conversations, including about their health.
bricolage/Shutterstock Causes and conditions
Conditions related to hearing and vision impairment often increase as we age – but many of these changes are subtle.
Hearing loss can start as early as our 50s and often accompany other age-related visual changes, such as age-related macular degeneration.
Other age-related conditions are frequently prioritised by patients, doctors or carers, such as diabetes or heart disease. Vision and hearing changes can be easy to overlook or accept as a normal aspect of ageing. As an older person we interviewed for our research told us
I don’t see too good or hear too well. It’s just part of old age.
An invisible disability
Dual sensory impairment has a significant and negative impact in all aspects of a person’s life. It reduces access to information, mobility and orientation, impacts social activities and communication, making it difficult for older adults to manage.
It is underdiagnosed, underrecognised and sometimes misattributed (for example, to cognitive impairment or decline). However, there is also growing evidence of links between dementia and dual sensory loss. If left untreated or without appropriate support, dual sensory impairment diminishes the capacity of older people to live independently, feel happy and be safe.
A dearth of specific resources to educate and support older Australians with their dual sensory impairment means when older people do raise the issue, their GP or health professional may not understand its significance or where to refer them. One older person told us:
There’s another thing too about the GP, the sort of mentality ‘well what do you expect? You’re 95.’ Hearing and vision loss in old age is not seen as a disability, it’s seen as something else.
Isolated yet more dependent on others
Global trends show a worrying conundrum. Older people with dual sensory impairment become more socially isolated, which impacts their mental health and wellbeing. At the same time they can become increasingly dependent on other people to help them navigate and manage day-to-day activities with limited sight and hearing.
One aspect of this is how effectively they can comprehend and communicate in a health-care setting. Recent research shows doctors and nurses in hospitals aren’t making themselves understood to most of their patients with dual sensory impairment. Good communication in the health context is about more than just “knowing what is going on”, researchers note. It facilitates:
- shorter hospital stays
- fewer re-admissions
- reduced emergency room visits
- better treatment adherence and medical follow up
- less unnecessary diagnostic testing
- improved health-care outcomes.
‘Too hard’
Globally, there is a better understanding of how important it is to maintain active social lives as people age. But this is difficult for older adults with dual sensory loss. One person told us
I don’t particularly want to mix with people. Too hard, because they can’t understand. I can no longer now walk into that room, see nothing, find my seat and not recognise [or hear] people.
Again, these experiences increase reliance on family. But caring in this context is tough and largely hidden. Family members describe being the “eyes and ears” for their loved one. It’s a 24/7 role which can bring frustration, social isolation and depression for carers too. One spouse told us:
He doesn’t talk anymore much, because he doesn’t know whether [people are] talking to him, unless they use his name, he’s unaware they’re speaking to him, so he might ignore people and so on. And in the end, I noticed people weren’t even bothering him to talk, so now I refuse to go. Because I don’t think it’s fair.
Dual sensory loss can be isolating for older people and carers. Synthex/Shutterstock So, what can we do?
Dual sensory impairment is a growing problem with potentially devastating impacts.
It should be considered a unique and distinct disability in all relevant protections and policies. This includes the right to dedicated diagnosis and support, accessibility provisions and specialised skill development for health and social professionals and carers.
We need to develop resources to help people with dual sensory impairment and their families and carers understand the condition, what it means and how everyone can be supported. This could include communication adaptation, such as social haptics (communicating using touch) and specialised support for older adults to navigate health care.
Increasing awareness and understanding of dual sensory impairment will also help those impacted with everyday engagement with the world around them – rather than the isolation many feel now.
