We all know that exercise is good for mental health as well as physical. So, what’s so revolutionary about this “revolutionary new science of exercise and the brain”?
A lot of it has to do with the specific neuroscience of how exercise has not only a mood-boosting effect (endorphins) and neuroprotective effect (helping to guard against cognitive decline), but also promotes neuroplasticity… e.g., the creation and strengthening of neural pathways, as well as boosting the structure of the brain in some parts such as the cerebellum.
The book also covers not just “exercise has these benefits”, but also the “how this works” of all kinds of brain benefits, including:
- against Alzheimer’s
- mitigating ADHD
- managing menopause
- dealing with addiction
…and more. And once we understand how something works, we’re far more likely to be motivated to actually do the kinds of exercises that give the specific benefits we want/need. Which is very much the important part!
In short: this book will tell you what you need to know to get you doing the exercises you need to enjoy those benefits—very much worth it!

Brain Food – by Dr. Lisa Mosconi

We know that we should eat for brain health, but often that knowledge doesn’t go a lot further than “we should eat some nuts… but also not the wrong nuts, which would be bad”.
However, as Dr. Lisa Mosconi lays out for us, there’s a lot more than that!
This book is as much a treatise of brain health in the context of nutrition, as it is a “eat this and avoid that” guide.
Which is good, because our brains don’t exist in isolation, and nor do the nutrients that we consume. Put it this way:
We have a tendecy to think of our diets as a set of slider-bars, “ok, that’s 104% of my daily intake of fiber, I need another 10g protein and that’ll be at 100%, I’ve had 80% of the vitamin C that I need, and…”
Whereas in reality: much of what we eat interacts positively or negatively with other things, and thus needs to be kept in balance. And not only that, but other peri-nutritional factors play a big part too! From obvious things like hydration, to less obvious things like maintaining good gut microbiota, our brains rely on us to do a lot of things for them.
This book is very easy-reading, though a weakness is it doesn’t tend to summarise key ideas much, give cheat-sheets, that sort of thing. We recommend reading this book with a notebook to the side, to jot down things you want to attend to in your own dietary habits.
Bottom line: this is an excellent overview of brain health in the context of nutrition, and is more comprehensive than most “eat this for good brain health and avoid that” books.

Fast-Pickled Cucumbers
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.
Pickled vegetables are great for the gut, and homemade is invariably better than store-bought. But if you don’t have pickling jars big enough for cucumbers, and don’t want to wait a couple of weeks for the results, here’s a great way to do it quickly and easily.
You will need
- 1 large cucumber, sliced
- 2 tbsp apple cider vinegar
- 1½ tbsp salt (do not omit or substitute)
- 3 cloves garlic, whole, peeled
- 3 large sprigs fresh dill
- 2 tsp whole black peppercorns
- ½ tsp crushed red pepper flakes
- 1 bay leaf
Method
(we suggest you read everything at least once before doing anything)
1) Mix the vinegar and salt with 1½ cups of water in a bowl.
2) Assemble the rest of the ingredients, except the cucumber, into a quart-size glass jar with an airtight lid.
3) Add the cucumber slices into the jar.
4) Add the pickling brine that you made, leaving ½” space at the top.
5) Close the lid, and shake well.
6) Refrigerate for 2 days, after which, serve at your leisure:
Enjoy!

Our ‘food environments’ affect what we eat. Here’s how you can change yours to support healthier eating
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 January, many people are setting new year’s resolutions around healthy eating. Achieving these is often challenging – it can be difficult to change our eating habits. But healthy diets can enhance physical and mental health, so improving what we eat is a worthwhile goal.
One reason it’s difficult to change our eating habits relates to our “food environments”. This term describes:
The collective physical, economic, policy and sociocultural surroundings, opportunities and conditions that influence people’s food and beverage choices and nutritional status.
Our current food environments are designed in ways that often make it easier to choose unhealthy foods than healthy ones. But it’s possible to change certain aspects of our personal food environments, making eating healthier a little easier.
Unhealthy food environments
It’s not difficult to find fast-food restaurants in Australian cities. Meanwhile, there are junk foods at supermarket checkouts, service stations and sporting venues. Takeaway and packaged foods and drinks routinely come in large portion sizes and are often considered tastier than healthy options.
Our food environments also provide us with various prompts to eat unhealthy foods via the media and advertising, alongside health and nutrition claims and appealing marketing images on food packaging.
At the supermarket, unhealthy foods are often promoted through prominent displays and price discounts.
We’re also exposed to various situations in our everyday lives that can make healthy eating challenging. For example, social occasions or work functions might see large amounts of unhealthy food on offer.
Not everyone is affected in the same way
People differ in the degree to which their food consumption is influenced by their food environments.
This can be due to biological factors (for example, genetics and hormones), psychological characteristics (such as decision making processes or personality traits) and prior experiences with food (for example, learned associations between foods and particular situations or emotions).
People who are more susceptible will likely eat more and eat more unhealthy foods than those who are more immune to the effects of food environments and situations.
Those who are more susceptible may pay greater attention to food cues such as advertisements and cooking smells, and feel a stronger desire to eat when exposed to these cues. Meanwhile, they may pay less attention to internal cues signalling hunger and fullness. These differences are due to a combination of biological and psychological characteristics.
These people might also be more likely to experience physiological reactions to food cues including changes in heart rate and increased salivation.
Other situational cues can also prompt eating for some people, depending on what they’ve learned about eating. Some of us tend to eat when we’re tired or in a bad mood, having learned over time eating provides comfort in these situations.
Other people will tend to eat in situations such as in the car during the commute home from work (possibly passing multiple fast-food outlets along the way), or at certain times of day such as after dinner, or when others around them are eating, having learned associations between these situations and eating.
Being in front of a TV or other screen can also prompt people to eat, eat unhealthy foods, or eat more than intended.
Making changes
While it’s not possible to change wider food environments or individual characteristics that affect susceptibility to food cues, you can try to tune into how and when you’re affected by food cues. Then you can restructure some aspects of your personal food environments, which can help if you’re working towards healthier eating goals.
Although both meals and snacks are important for overall diet quality, snacks are often unplanned, which means food environments and situations may have a greater impact on what we snack on.
Foods consumed as snacks are often sugary drinks, confectionery, chips and cakes. However, snacks can also be healthy (for example, fruits, nuts and seeds).
Try removing unhealthy foods, particularly packaged snacks, from the house, or not buying them in the first place. This means temptations are removed, which can be especially helpful for those who may be more susceptible to their food environment.
Planning social events around non-food activities can help reduce social influences on eating. For example, why not catch up with friends for a walk instead of lunch at a fast-food restaurant.
Creating certain rules and habits can reduce cues for eating. For example, not eating at your desk, in the car, or in front of the TV will, over time, lessen the effects of these situations as cues for eating.
You could also try keeping a food diary to identify what moods and emotions trigger eating. Once you’ve identified these triggers, develop a plan to help break these habits. Strategies may include doing another activity you enjoy such as going for a short walk or listening to music – anything that can help manage the mood or emotion where you would have typically reached for the fridge.
Write (and stick to) a grocery list and avoid shopping for food when hungry. Plan and prepare meals and snacks ahead of time so eating decisions are made in advance of situations where you might feel especially hungry or tired or be influenced by your food environment.

It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
Q: What’s a worthwhile fitness goal for people in their 50s?
A: At 10almonds, we think that goals are great but habits are better.
If your goal is to run a marathon, that’s a fine goal, and can be very motivating, but then after the marathon, then what? You’ll look back on it as a great achievement, but what will it do for your future health?
PS, yes, marathon-running in one’s middle age is a fine and good activity for most people. Maybe skip it if you have osteoporosis or some other relevant problem (check with your doctor), but…
Marathons in Mid- and Later-Life ← we wrote about the science of it here
PS, we also explored some science that may be applicable to your other question, on the same page as that about marathons!
The thing about habits vs goals is that habits give ongoing cumulative (often even: compounding) benefits:
How To Really Pick Up (And Keep!) Those Habits
If you pressingly want advice on goals though, our advice is this:
Make it your goal to be prepared for the health challenges of later life. It may seem gloomy to say that old age is coming for us all if something else doesn’t get us first, but the fact is, old age does not have to come with age-related decline, and the very least, we can increase our healthspan (so we’re hitting 90 with most of the good health we enjoyed in our 70s, for example, or hitting 80 with most of the good health we enjoyed in our 60s).
If that goal seems a little wishy-washy, here are some very specific and practical ideas to get you started:
Train For The Event Of Your Life!
As for the limits and/or extents of how much we can do in that regard? Here are what two aging experts have to say:

Antidepressants: Personalization Is Key!
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.
Antidepressants: Personalization Is Key!
Yesterday, we asked you for your opinions on antidepressants, and got the above-depicted, below-described, set of responses:
- Just over half of respondents said “They clearly help people, but should not be undertaken lightly”
- Just over a fifth of respondents said “They may help some people, but the side effects are alarming”
- Just under a sixth of respondents said “They’re a great way to correct an imbalance of neurochemicals”
- Four respondents said “They are no better than placebo, and are more likely to harm”
- Two respondents said “They merely mask the problem, and thus don’t really help”
So what does the science say?
❝They are no better than placebo, and are more likely to harm? True or False?❞
True or False depending on who you are and what you’re taking. Different antidepressants can work on many different systems with different mechanisms of action. This means if and only if you’re not taking the “right” antidepressant for you, then yes, you will get only placebo benefits:
- Placebo Effect in the Treatment of Depression and Anxiety ← randomly assigned antidepressants are, shockingly, luck of the draw in usefulness
- Antidepressants versus placebo in major depression: an overview ← “wow this science is messy”
- Comparative efficacy and acceptability of 21 antidepressant drugs: a systematic review and network meta-analysis ← “oh look, it makes a difference which antidepressant we give to people”
Rather than dismissing antidepressants as worthless, therefore, it is a good idea to find out (by examination or trial and error) what kind of antidepressant you need, if you indeed do need such.
Otherwise it is like getting a flu shot and being surprised when you still catch a cold!
❝They merely mask the problem, and thus don’t really help: True or False?❞
False, categorically.
The problem in depressed people is the depressed mood. This may be influenced by other factors, and antidepressants indeed won’t help directly with those, but they can enable the person to better tackle them (more on this later).
❝They may help some people, but the side-effects are alarming: True or False?❞
True or False depending on more factors than we can cover here.
Side-effects vary from drug to drug and person to person, of course. As does tolerability and acceptability, since to some extent these things are subjective.
One person’s dealbreaker may be another person’s shrugworthy minor inconvenience at most.
❝They’re a great way to correct an imbalance of neurochemicals: True or False?❞
True! Contingently.
That is to say: they’re a great way to correct an imbalance of neurochemicals if and only if your problem is (at least partly) an imbalance of neurochemicals. If it’s not, then your brain can have all the neurotransmitters it needs, and you will still be depressed, because (for example) the other factors* influencing your depression have not changed.
*common examples include low self-esteem, poor physical health, socioeconomic adversity, and ostensibly bleak prospects for the future.
For those for whom the problem is/was partly a neurochemical imbalance and partly other factors, the greatest help the antidepressants give is getting the brain into sufficient working order to be able to tackle those other factors.

Here’s a helpful side-by-side comparison of common antidepressants, what type they are, and other considerations:
