We’ve reviewed a number of “improve your brain health” books over time, and this one’s quite different. How?
Most of the books we’ve reviewed have been focused on optimizing diet and exercise for brain health with a nod to other factors… This one focuses more on those other factors.
While this book does reference a fair bit of hard science, much of it is written more like a pop psychology book. As a result, most of the actionable advices, of which there are many, pertain to cognitive and behavioral adjustments.
And no, this is not a book of Cognitive Behavioral Therapy. It just happened to also address those two aspects.
We learn, for example, how our neurochemistry influences us—but also how we can influence our neurochemistry.
We also learn the oft-neglected (in other books!) social factors that influence brain health. Not just for our happiness, but for our productivity and peak cognitive performance too. Halford talks us through optimizing these such that we and those around us all get to enjoy the best brain benefits available to each of us.
The format of the book is that each chapter explains what you need to know for a given “activation” as the author calls it, and then an exercise to try out. With fifteen such chapters, every reader is bound to find at least something new.
Bottom line: if you want to grease those synapses in more ways than just eating some nuts and berries and getting good sleep and exercise, this book is a great resource.

The Many Health Benefits Of Garlic
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 Many Health Benefits of Garlic
We’re quite confident you already know what garlic is, so we’re going to leap straight in there with some science today:
First, let’s talk about allicin
Allicin is a compound in garlic that gives most of its health benefits. A downside of allicin is that it’s not very stable, so what this means is:
- Garlic is best fresh—allicin breaks down soon after garlic is cut/crushed
- So while doing the paperwork isn’t fun, buying it as bulbs is better than buying it as granules or similar
- Allicin also breaks down somewhat in cooking, so raw garlic is best
- Our philosophy is: still use it in cooking as well; just use more!
- Supplements (capsule form etc) use typically use extracts and potency varies (from not great to actually very good)
Read more about that:
- Short-term heating reduces the anti-inflammatory effects of fresh raw garlic extracts
- Allicin Bioavailability and Bioequivalence from Garlic Supplements and Garlic Foods
Now, let’s talk benefits…
Benefits to heart health
Garlic has been found to be as effective as the drug Atenolol at reducing blood pressure:
It also lowers LDL (bad cholesterol):
Benefits to the gut
We weren’t even looking for this, but as it turns out, as an add-on to the heart benefits…
Benefits to the immune system
Whether against the common cold or bringing out the heavy guns, garlic is a booster:
- Preventing the common cold with a garlic supplement: a double-blind, placebo-controlled survey
- Supplementation with aged garlic extract improves both NK and γδ-T cell function and reduces the severity of cold and flu symptoms: a randomized, double-blind, placebo-controlled nutrition intervention
Benefits to the youthfulness of body and brain
Garlic is high in antioxidants that, by virtue of reducing oxidative stress, help slow aging. This effect, combined with the cholesterol and blood pressure benefits, means it may also reduce the risk of Alzheimer’s and other forms of dementia:
- Antioxidant health effects of aged garlic extract
- Effects of garlic consumption on plasma and erythrocyte antioxidant parameters in elderly subjects
- Garlic reduces heart disease and dementia risk
There are more benefits too…
That’s all we have time to dive into study-wise today, but for the visually-inclined, here are yet more benefits to garlic (at a rate of 3–4 cloves per day):
An incredible awesome recipe using lots of garlic:
- Take small potatoes (still in their skins), cut in half
- Add enough peeled cloves of garlic so that you have perhaps a 1:10 ratio of garlic to potato by mass
- Boil (pressure-cooking is ideal) until soft, and drain
- Keeping them in the pan, add a lashing of olive oil, and any additional seasonings per your preference (consider black pepper, rosemary, thyme, parsley)
- Put a lid on the pan, and holding it closed, shake the pan vigorously
- Note: if you didn’t leave the skins on, or you chopped much larger potatoes smaller instead of cutting in half, the potatoes will break up into a rough mash now. This is actually also fine and still tastes (and honestly, looks) great, but it is different, so just be aware, so that you get the outcome you want.
- The garlic, which—unlike the potatoes—didn’t have a skin to hold it together, will now have melted over the potatoes like butter
You can serve like this (it’s delicious already) or finish up in the oven or air-fryer or under the grill, if you prefer a roasted style dish (an amazing option too).

Younger Next Year – by Chris Crowley & Dr. Henry Lodge

Is it diet and exercise? Well, of course that’s a component. Specific kinds of exercise, too. But, as usual when we feature a book, there’s more:
In this case, strong throughout is the notion of life being a marathon not a sprint—and training for it accordingly.
Doing the things now that you’ll really wish you’d started doing sooner, and finding ways to build them into daily life.
Not just that, though! The authors take a holistic approach to life and health, and thus also cover work life, social life, and so forth. Now, you may be thinking “I’m already in the 80 and beyond category; I don’t work” and well, the authors advise that you do indeed work. You don’t have to revamp your career, but science strongly suggests that people who work longer, live longer.
Of course that doesn’t have to mean going full-throttle like a 20-year-old determined to make their mark on the world (you can if you want, though). It could be volunteering for a charity, or otherwise just finding a socially-engaging “work-like” activity that gives you purpose.
About the blend of motivational pep talk and science—this book is heavily weighted towards the former. It has, however, enough science to keep it on the right track throughout. Hence the two authors! Crowley for motivational pep, and Dr. Lodge for the science (with extra input from brain surgeon Dr. Hamilton, too).
Bottom line: if you want to feel the most prepared possible for the coming years and decades, this is a great book that covers a lot of bases.

Things Many People Forget When It Comes To Hydration
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.
Good hydration is about more than just “drink lots of water”, and in fact it’s quite possible for a person to drink too much water, and at the same time, be dehydrated. Here’s how and why and what to do about it:
Water, water, everywhere
Factors that people forget:
- Electrolyte balance: without it, we can technically have lots of water while either retaining it (in the case of too high salt levels) or peeing it out (in the case of too low salt levels), neither of which are as helpful as getting it right and actually being able to use the water.
- Gastrointestinal health: conditions like IBS, Crohn’s, or celiac disease can impair water and nutrient absorption, affecting hydration
- Genetic factors: some people simply have a predisposition to need more or less water for proper hydration
- Dietary factors: high salt, caffeine, and alcohol intake (amongst other diuretics) can increase water loss, while water-rich foods (assuming they aren’t also diuretics) increase hydration.
Strategies to do better:
- Drink small amounts of water consistently throughout the day rather than large quantities at once—healthy kidneys can process about 1 liter (about 1 quart) of water per hour, so drinking more than that will not help, no matter how dehydrated you are when you start. If your kidneys aren’t in peak health, the amount processable per hour will be lower for you.
- Increase fiber intake (e.g., fruit and vegetables) to retain water in the intestines and improve hydration
- Consume water-rich foods (e.g., watermelon, cucumbers, grapes) to enhance overall hydration and support cellular function (the body can use this a lot more efficiently than if you just drink water).
- Counteract the diuretic effects of caffeine and alcohol by drinking an additional 12 oz of water for every 8 oz of these beverages. Best yet, don’t drink alcohol and keep caffeine to a low level (or quit entirely, if you prefer, but for most people that’s not necessary).
- If you are sweating (be it because of weather, exercise, or any other reasons), include electrolyte fluids to improve cellular hydration, as they contain essential minerals like magnesium, potassium, and in moderation yes even sodium which you will have lost in your sweat too, supporting fluid regulation.

Anti-Inflammatory Cookbook for Beginners – by Melissa Jefferson
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.
For some of us, avoiding inflammatory food is a particularly important consideration. For all of us, it should be anyway.
Sometimes, we know what’s good against inflammation, and we know what’s bad for inflammation… but we might struggle to come up with full meals of just-the-good, especially if we want to not repeat meals every day!
The subtitle is slightly misleading! It says “Countless Easy and Delicious Recipes”, but this depends on your counting ability. Melissa Jefferson gives us 150 anti-inflammatory recipes, which can be combined for a 12-week meal plan. We think that’s enough to at least call it “many”, though.
First comes an introduction to inflammation, inflammatory diseases, and a general overview of what to eat / what to avoid. After that, the main part of the book is divided into sections:
- Breakfasts (20)
- Soups (15)
- Beans & Grains (20)
- Meat (20)
- Fish (20)
- Vegetables (20)
- Sides (15)
- Snacks (10)
- Desserts (10)
If you’ve a knowledge of anti-inflammation diet already, you may be wondering how “Meat” and “Desserts” works.
- The meat section is a matter of going light on the meat and generally favoring white meats, and certainly unprocessed.
- Of course, if you are vegetarian or vegan, substitutions may be in order anyway.
As for the dessert section? A key factor is that fruits and chocolate are anti-inflammatory foods! Just a matter of not having desserts full of sugar, flour, etc.
The recipes themselves are simple and to-the-point, with ingredients, method, and nutritional values. Just the way we like it.
All in all, a fine addition to absolutely anyone’s kitchen library… And doubly so if you have a particular reason to focus on avoiding/reducing inflammation!

Vaginal Probiotics: What Does The Science Say?
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? 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 😎
❝Is there any merit to vaginal probiotics?❞
What a fun question! First let’s break it down, as this could mean two different things:
- Probiotics, which you consume, using your mouth, which are marketed as benefiting vaginal health
- Probiotics taken as a vaginal pessary/suppository, to act directly there
The former has limited evidence for it, but generally speaking, improving one’s gut health improves all other areas of health, so it’s not surprising if it helps this too.
See for example:
Some notes:
- candidal vaginitis means a yeast infection causing vaginal inflammation
- bacterial vaginosis means a vaginal bacterial imbalance (generally also featuring vaginal inflammation, though it can be asymptomatic)
In the latter case, the “imbalance” in question is usually a shortage of Lactobacillus sp. (that is to say, the diverse species of the Lactobacillus genus) resulting in an overgrowth of other kinds of bacteria, which in turn results in changing the vaginal microbiome to make it warmer and more acidic than it should be.
While a healthy vagina shouldn’t smell of roses, it shouldn’t smell fishy either; if it does, that’s a sign of bacterial vaginosis.
What it’s supposed to be like: slightly bitter, slightly salty, distinctly umami, along with a cocktail of personal pheromones (and if menstruating or otherwise* vaginally bleeding, then of course add: iron/”metallic”). The pheromones will also reflect any hormonal changes, but should never make anything smell bad, just different.
*e.g. due to PCOS, fibroids, etc. Note that in the case of PCOS, it may also smell a little different (if it does, then usually: a little more musky), due to often different hormone levels. Again: it still shouldn’t smell bad, though, just different.
In the above-linked study, taking more live Lactobacillus acidophilus (in yogurt, eating it, with their mouths) improved levels of L. acidophilus in the vagina. While the study authors concluded “this ingestion of yogurt may have reduced episodes of bacterial vaginosis”, which is rather a weak claim, it can be argued that it merely improving the levels of L. acidophilus in the vagina was already a win.
That was a small (n=42, and only 7 followed through to completion) and old (1996) study, and it bears mentioning that most of the studies into this seem to be small and old, but conclude similarly with weakly positive statements.
However, it does make a difference what kind of Lactobacillus is used, for example in this next study…
- L. fermentum RC-14 worked well (90% success rate)
- L. rhamnosus GR-1 worked somewhat (40% success rate)
- L. rhamnosus GG did not work (0% success rate)
So, diversity is key, and getting a wide range of Lactobacillus sp. seems to be a safe bet.
Short version: enjoying probiotics as part of your diet probably improves vaginal health, just like it improves pretty much everything else.

You would think that this would mean that taking probiotics as a vaginal pessary/suppository would be even better, but the results are weaker, as in this study, which produced temporary improvements in about half the study group, with only 3 out of 28 being free of bacterial vaginosis the next month:
Treatment of bacterial vaginosis with lactobacilli
This study got better results, with a 61% success rate:
Important note
Do note that this last category, involving topical treatments (i.e., manually introducing Lactobacillus sp. to the vagina) were all in cases of pre-existing bacterial vaginosis, not as a prophylactic and/or general health-improving thing.
If your vagina seems happy right now, then do not mess with its happy bacterial balance!
And at all times (regardless of whether it seems happy right now or not): do not douche (it does not need it and will not benefit from it; the vagina is self-cleaning*) as this will wash out many of your Lactobacilli and will do absolutely nothing against any Candida there (C. albicans being a rooted fungus, whereas Lactobacillus is a sausage-shaped bacterium with many tiny appendages but no actual ability to stay put), so Candida will flourish in the Lactobacillus’s absence.
*by the vagina, we are referring to the vaginal canal. The vulva—the outside part consisting of the two pairs of labia, the glans clitoris, and clitoral hood—are not self-cleaning, and should just be washed gently per your normal bath/shower routine; that’s perfectly fine and good.
And definitely don’t put any “cleansing” toiletries inside the vagina (or any toiletries at all, for that matter), even if they are sold and marketed for that purpose; they will not help and they will harm.
Also, due to their neighborliness, messing up the microbiome inside the vagina is a common way to also get Candida inside the urethra:

One other option
Finally, unless you have a “very good friend” you have a pressing urge to swap germs with, you might want to leave this one to the scientists, but we share this paper just for interest:

Pink Himalayan Salt: Health Facts
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!
Q: Great article about the health risks of salt to organs other than the heart! Is pink Himalayan sea salt, the pink kind, healthier?
Thank you! And, no, sorry. Any salt that is sodium chloride has the exact same effect because it’s chemically the same substance, even if impurities (however pretty) make it look different.
If you want a lower-sodium salt, we recommend the kind that says “low sodium” or “reduced sodium” or similar. Check the ingredients, it’ll probably be sodium chloride cut with potassium chloride. Potassium chloride is not only not a source of sodium, but also, it’s a source of potassium, which (unlike sodium) most of us could stand to get a little more of.
For your convenience: here’s an example on Amazon!
Bonus: you can get a reduced sodium version of pink Himalayan salt too!
