How To Grow New Brain Cells (At Any Age)
It was long believed that brain growth could not occur later in life, due to expending our innate stock of pluripotent stem cells. However, this was mostly based on rodent studies.
Rodent studies are often used for brain research, because it’s difficult to find human volunteers willing to have their brains sliced thinly (so that the cells can be viewed under a microscope) at the end of the study.
However, neurobiologist Dr. Maura Boldrini led a team that did a lot of research by means of autopsies on the hippocampi of (previously) healthy individuals ranging in age from 14 to 79.
What she found is that while indeed the younger subjects did predictably have more young brain cells (neural progenitors and immature neurons), even the oldest subject, at the age of 79, had been producing new brain cells up until death.
Read her landmark study: Human Hippocampal Neurogenesis Persists throughout Aging
There was briefly a flurry of news articles about a study by Dr. Shawn Sorrels that refuted this, however, it later came to light that Dr. Sorrels had accidentally destroyed his own evidence during the cell-fixing process—these things happen; it’s just unfortunate the mistake was not picked up until after publication.
A later study by a Dr. Elena Moreno-Jiménez fixed this flaw by using a shorter fixation time for the cell samples they wanted to look at, and found that there were tens of thousands of newly-made brain cells in samples from adults ranging from 43 to 87.
Now, there was still a difference: the samples from the youngest adult had 30% more newly-made braincells than the 87-year-old, but given that previous science thought brain cell generation stopped in childhood, the fact that an 87-year-old was generating new brain cells 30% less quickly than a 43-year-old is hardly much of a criticism!
As an aside: samples from patients with Alzheimer’s also had a 30% reduction in new braincell generation, compared to samples from patients of the same age without Alzheimer’s. But again… Even patients with Alzheimer’s were still growing some new brain cells.
Read it for yourself: Adult hippocampal neurogenesis is abundant in neurologically healthy subjects and drops sharply in patients with Alzheimer’s disease
Practical advice based on this information
Since we can do neurogenesis at any age, but the rate does drop with age (and drops sharply in the case of Alzheimer’s disease), we need to:
Feed your brain. The brain is the most calorie-consuming organ we have, by far, and it’s also made mostly of fat* and water. So, get plenty of healthy fats, and get plenty of water.
*Fun fact: while depictions in fiction (and/or chemically preserved brains) may lead many to believe the brain has a rubbery consistency, the untreated brain being made of mostly fat and water gives it more of a blancmange-like consistency in reality. That thing is delicate and spatters easily. There’s a reason it’s kept cushioned inside the strongest structure of our body, far more protected than anything in our torso.
Exercise. Specifically, exercise that gets your blood pumping. This (as our earlier-featured video today referenced) is one of the biggest things we can do to boost Brain-Derived Neurotrophic Factor, or BDNF.
Here be science: Brain-Derived Neurotrophic Factor, Depression, and Physical Activity: Making the Neuroplastic Connection
However, that’s not the only way to increase BDNF; another is to enjoy a diet rich in polyphenols. These can be found in, for example, berries, tea, coffee, and chocolate. Technically those last two are also botanically berries, but given how we usually consume them, and given how rich they are in polyphenols, they merit a special mention.
See for example: Effects of nutritional interventions on BDNF concentrations in humans: a systematic review
Some supplements can help neuron (re)growth too, so if you haven’t already, you might want to check out our previous main feature on lion’s mane mushroom, a supplement which does exactly that.

I’ve been diagnosed with cancer. How do I tell my children?
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 around one in 50 adults diagnosed with cancer each year, many people are faced with the difficult task of sharing the news of their diagnosis with their loved ones. Parents with cancer may be most worried about telling their children.
It’s best to give children factual and age-appropriate information, so children don’t create their own explanations or blame themselves. Over time, supportive family relationships and open communication help children adjust to their parent’s diagnosis and treatment.
It’s natural to feel you don’t have the skills or knowledge to talk with your children about cancer. But preparing for the conversation can improve your confidence.
Preparing for the conversation
Choose a suitable time and location in a place where your children feel comfortable. Turn off distractions such as screens and phones.
For teenagers, who can find face-to-face conversations confronting, think about talking while you are going for a walk.
Consider if you will tell all children at once or separately. Will you be the only adult present, or will having another adult close to your child be helpful? Another adult might give your children a person they can talk to later, especially to answer questions they might be worried about asking you.
Finally, plan what to do after the conversation, like doing an activity with them that they enjoy. Older children and teenagers might want some time alone to digest the news, but you can suggest things you know they like to do to relax.
Also consider what you might need to support yourself.
Preparing the words
Parents might be worried about the best words or language to use to make sure the explanations are at a level their child understands. Make a plan for what you will say and take notes to stay on track.
The toughest part is likely to be saying to your children that you have cancer. It can help to practise saying those words out aloud.
Ask family and friends for their feedback on what you want to say. Make use of guides by the Cancer Council, which provide age-appropriate wording for explaining medical terms like “cancer”, “chemotherapy” and “tumour”.
Having the conversation
Being open, honest and factual is important. Consider the balance between being too vague, and providing too much information. The amount and type of information you give will be based on their age and previous experiences with illness.
Remember, if things don’t go as planned, you can always try again later.
Start by telling your children the news in a few short sentences, describing what you know about the diagnosis in language suitable for their age. Generally, this information will include the name of the cancer, the area of the body affected and what will be involved in treatment.
Let them know what to expect in the coming weeks and months. Balance hope with reality. For example:
The doctors will do everything they can to help me get well. But, it is going to be a long road and the treatments will make me quite sick.
Check what your child knows about cancer. Young children may not know much about cancer, while primary school-aged children are starting to understand that it is a serious illness. Young children may worry about becoming unwell themselves, or other loved ones becoming sick.
Older children and teenagers may have experiences with cancer through other family members, friends at school or social media.
This process allows you to correct any misconceptions and provides opportunities for them to ask questions. Regardless of their level of knowledge, it is important to reassure them that the cancer is not their fault.
Ask them if there is anything they want to know or say. Talk to them about what will stay the same as well as what may change. For example:
You can still do gymnastics, but sometimes Kate’s mum will have to pick you up if I am having treatment.
If you can’t answer their questions, be OK with saying “I’m not sure”, or “I will try to find out”.
Finally, tell children you love them and offer them comfort.
How might they respond?
Be prepared for a range of different responses. Some might be distressed and cry, others might be angry, and some might not seem upset at all. This might be due to shock, or a sign they need time to process the news. It also might mean they are trying to be brave because they don’t want to upset you.
Children’s reactions will change over time as they come to terms with the news and process the information. They might seem like they are happy and coping well, then be teary and clingy, or angry and irritable.
Older children and teenagers may ask if they can tell their friends and family about what is happening. It may be useful to come together as a family to discuss how to inform friends and family.
What’s next?
Consider the conversation the first of many ongoing discussions. Let children know they can talk to you and ask questions.
Resources might also help; for example, The Cancer Council’s app for children and teenagers and Redkite’s library of free books for families affected by cancer.
If you or other adults involved in the children’s lives are concerned about how they are coping, speak to your GP or treating specialist about options for psychological support.

Focusing On Health In Our Sixties
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’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
❝What happens when you age in your sixties?❞
The good news is, a lot of that depends on you!
But, speaking on averages:
While it’s common for people to describe being over 50 as being “over the hill”, halfway to a hundred, and many greetings cards and such reflect this… Biologically speaking, our 60s are more relevant as being halfway to our likely optimal lifespan of 120. Humans love round numbers, but nature doesn’t care for such.
- In our 60s, we’re now usually the “wrong” side of the menopausal metabolic slump (usually starting at 45–55 and taking 5–10 years), or the corresponding “andropause” where testosterone levels drop (usually starting at 45 and a slow decline for 10–15 years).
- In our 60s, women will now be at a higher risk of osteoporosis, due to the above. The risk is not nearly so severe for men.
- In our 60s, if we’re ever going to get cancer, this is the most likely decade for us to find out.
- In our 60s, approximately half of us will suffer some form of hearing loss
- In our 60s, our body has all but stopped making new T-cells, which means our immune defenses drop (this is why many vaccines/boosters are offered to over-60s, but not to younger people)
While at first glance this does not seem a cheery outlook, knowledge is power.
- We can take HRT to avoid the health impact of the menopause/andropause
- We can take extra care to look after our bone health and avoid osteoporosis
- We can make sure we get the appropriate cancer screenings when we should
- We can take hearing tests, and if appropriate find the right hearing aids for us
- We can also learn to lip-read (this writer relies heavily on lip-reading!)
- We can take advantage of those extra vaccinations/boosters
- We can take extra care to boost immune health, too
Your body has no idea how many times you’ve flown around the sun and nor does it care. What actually makes a difference to it, is how it has been treated.

ADHD medication – can you take it long term? What are the risks and do benefits continue?
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.
Attention deficit hyperactivity disorder (ADHD) is a condition that can affect all stages of life. Medication is not the only treatment, but it is often the treatment that can make the most obvious difference to a person who has difficulties focusing attention, sitting still or not acting on impulse.
But what happens once you’ve found the medication that works for you or your child? Do you just keep taking it forever? Here’s what to consider.
What are ADHD medications?
The mainstay of medication for ADHD is stimulants. These include methylphenidate (with brand names Ritalin, Concerta) and dexamfetamine. There is also lisdexamfetamine (branded Vyvanse), a “prodrug” of dexamfetamine (it has a protein molecule attached, which is removed in the body to release dexamfetamine).
There are also non-stimulants, in particular atomoxetine and guanfacine, which are used less often but can also be highly effective. Non-stimulants can be prescribed by GPs but this may not always be covered by the Pharmaceutical Benefits Scheme and could cost more.
How stimulants work
Some stimulants prescribed for ADHD are “short acting”. This means the effect comes on after around 20 minutes and lasts around four hours.
Longer-acting stimulants give a longer-lasting effect, usually by releasing medication more slowly. The choice between the two will be guided by whether the person wants to take medication once a day or prefers to target the medication effect to specific times or tasks.
For the stimulants (with the possible exception of lisdexamfetamine) there is very little carry-over effect to the next day. This means the symptoms of ADHD may be very obvious until the first dose of the morning takes effect.
One of the main aims of treatment is the person with ADHD should live their best life and achieve their goals. In young children it is the parents who have to consider the risks and benefits on behalf of the child. As children mature, their role in decision making increases.
What about side effects?
The most consistent side effects of the stimulants are they suppress appetite, resulting in weight loss. In children this is associated with temporary slowing of the growth rate and perhaps a slight delay in pubertal development. They can also increase the heart rate and may cause a rise in blood pressure. Stimulants often cause insomnia.
These changes are largely reversible on stopping medication. However, there is concern the small rises in blood pressure could accelerate the rate of heart disease, so people who take medication over a number of years might have heart attacks or strokes slightly sooner than would have happened otherwise.
This does not mean older adults should not have their ADHD treated. Rather, they should be aware of the potential risks so they can make an informed decision. They should also make sure high blood pressure and attacks of chest pain are taken seriously.
Stimulants can be associated with stomach ache or headache. These effects may lessen over time or with a reduction in dose. While there have been reports about stimulants being misused by students, research on the risks of long-term prescription stimulant dependence is lacking.
Will medication be needed long term?
Although ADHD can affect a person’s functioning at all stages of their life, most people stop medication within the first two years.
People may stop taking it because they don’t like the way it makes them feel, or don’t like taking medication at all. Their short period on medication may have helped them develop a better understanding of themselves and how best to manage their ADHD.
In teenagers the medication may lose its effectiveness as they outgrow their dose and so they stop taking it. But this should be differentiated from tolerance, when the dose becomes less effective and there are only temporary improvements with dose increases.
Tolerance may be managed by taking short breaks from medication, switching from one stimulant to another or using a non-stimulant.
Too many prescriptions?
ADHD is becoming increasingly recognised, with more people – 2–5% of adults and 5–10% of children – being diagnosed. In Australia stimulants are highly regulated and mainly prescribed by specialists (paediatricians or psychiatrists), though this differs from state to state. As case loads grow for this lifelong diagnosis, there just aren’t enough specialists to fit everyone in.
In November, a Senate inquiry report into ADHD assessment and support services highlighted the desperation experienced by people seeking treatment.
There have already been changes to the legislation in New South Wales that may lead to more GPs being able to treat ADHD. Further training could help GPs feel more confident to manage ADHD. This could be in a shared-care arrangement or independent management of ADHD by GPs like a model being piloted at Nepean Blue Mountains Local Health District, with GPs training within an ADHD clinic (where I am a specialist clinician).
Not every person with ADHD will need or want to take medication. However, it should be more easily available for those who could find it helpful.

The Connection Cure – by Julia Hotz
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.
You may recognize some of the things in the subtitle as being notable elements of the Blue Zones supercentenarians’ lifestyles, but this book looks at numerous quite diverse countries, and people from many walks of life.
What they have in common—and this is mostly a very person-centered book, relying a lot on case studies, with additional references coming from wider sociological data—is social prescribing.
What is social prescribing? That’s what the author (a journalist by general profession) answers comprehensively here, and it’s about looking at the ways medical problems can often have nonmedical solutions. It doesn’t necessarily mean that walking will cure your cancer or art will cure your diabetes, but it does mean that very often a key part of an unhealthy lifestyle is fundamentally something that can be fixed by one or more of: movement, nature, art, service, and belonging.
She looks at social prescribing in its birthplace (the UK, where cheap solutions that are nevertheless evidence-based are very much prioritized), in big countries like Canada and Australia, in aging countries like Singapore and South Korea, and yes, also in the #1 country of pill prescribing, the US.
The structure of the book is interesting, we first have 5 person-centered chapters addressing each of the social prescribing aspects and how they helped in two example case studies for each one, then 5 country-by-country epidemiological chapters looking at the big picture, then 5 person-centered chapters again, this time looking at personalizing social prescribing for oneself (this section of the book being headed “Social Prescribing For You And Me”), looking at what is going on in one’s life and health, which of the 5 elements might be missing, and what tangible goal-oriented benefits can—according to the evidence—be obtained by tending to what one actually needs in terms of social prescribing.
The style is narrative and journalistic, with very little hard science, but very little that’s wishy-washy either. It is, in short, a pleasant and informative read that helps the reader really understand social prescribing, the better to implement it in our own lives.
Bottom line: if you like having extra nonmedical approaches to avoid or alleviate medical problems, then this book will really help you achieve that.

Macadamias vs Hazelnuts – 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 macadamias to hazelnuts, we picked the hazelnuts.
Why?
In terms of macros first, hazelnuts have 2x the protein, and slightly more carbs and fiber. We call this a win for hazelnuts.
When it comes to vitamins, macadamias have more of vitamins B1, B2, and B3, while hazelnuts have more of vitamins A, B5, B6, B7, B9, C, and E. Notably, 28x more vitamin E, so that’s not inconsiderable. Also 10x the vitamin B9, and 5x the vitamin C, and the rest, more modest wins. In any case, clearly a strong win for hazelnuts here.
In the category of minerals, macadamias have more selenium, while hazelnuts have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc. Another clear win for hazelnuts.
In short, hazelnuts win in all categories. However, by all means enjoy either or both (unless you have a nut allergy, in which case, obviously don’t).

The Green Roasting Tin – by Rukmini Iyer
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.
You may be wondering: “do I really need a book to tell me to put some vegetables in a roasting tin and roast them?” and maybe not, but the book offers a lot more than that.
Indeed, the author notes “this book was slightly in danger of becoming the gratin and tart book, because I love both”, but don’t worry, most of the recipes are—as you might expect—very healthy.
As for formatting: the 75 recipes are divided first into vegan or vegetarian, and then into quick/medium/slow, in terms of how long they take.
However, even the “slow” recipes don’t actually take more effort, just, more time in the oven.
One of the greatest strengths of this book is that not only does it offer a wide selection of wholesome mains, but also, if you’re putting on a big spread, these can easily double up as high-class low-effort sides.
Bottom line: if you’d like to eat more vegetables in 2024 but want to make it delicious and with little effort, put this book on your Christmas list!
