Cure this serious disease with diet!” is often a bold-claim that overreaches scientific rigor, but in this case, it’s well-established as scientifically valid.
Caveat up-front: the only known circumstance in which this won’t work is if you have comorbidities that prevent you from following the advice.
You may be wondering: is this just the Mediterranean diet again? The answer is that the Mediterreanean diet (or similar) is part of it. But there’s a lot more to this book than that.
Dr. Fung explains to us a lot of the physiology of type 2 diabetes; how insulin resistance occurs, how it becomes a vicious cycle that we get locked into, and how to escape it.
- We learn about the role of fructose, and why fruit is very healthful whereas high-fructose corn syrup and similars are very much not.
- We learn about the role of the liver in glycogen metabolism, and how to un-fatty a fatty liver. Good news: the liver has famously strong self-regenerative abilities, if we give it a break to allow it to do so!
- We learn why portion control doesn’t work, and why intermittent fasting does (here be science).
Dr. Fung’s very readable explanations are free from needless jargon while not dumbing down. The writing style is clear and direct: “this happens this way”, “do this, not that”, etc.
Bottom line: if you have type 2 diabetes and would like to not have that (or if you are pre-diabetic and would like to avoid diabetes) this is a book for you. If you are in great metabolic health and would like to stay that way as you get older, then this is a book for you too.

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 is Mediterranean diet which book to read?❞
We did a special edition about the Mediterranean Diet! So that’s a great starting point.
As to books, there are so many, and we review books about it from time to time, so keep an eye out for our daily “One-Minute Book Review” section. We do highly recommend “How Not To Die”, which is a science-heavy approach to diet-based longevity, and essentially describes the Mediterranean Diet, with some tweaks.
❝I’m interested in the benefits of gardening. I read something about how important it is for humans to have a connection with soil, with dirt. That its benefits go way beyond growing food to eat or getting exercise. I’d like to find out more.❞
You’re quite right! There are bacteria in soil (specifically: Mycobacterium vaccae) that work similarly to antidepressants.
When something is described as having an effect similar to antidepressants, it’s usually hyperbole. In this case, it’s medicine, and literally works directly on the serotonergic system (as do many, but not all, antidepressants).
While many antidepressants are selective serotonin uptake inhibitors (i.e., they slow the rate at which your brain loses serotonin), Mycobacterium vaccae increases the rate at which you produce serotonin. So, you feel happier, more relaxed, while also feeling more energized.
^this one’s a mouse study, but we’re including it because it covers exactly how it works in the brain, which is something that the ethics board wouldn’t let them do on humans.
As to how to enjoy its benefits? Gardening! You don’t have to go to the length of eating dirt or anything; so long as you’re not gardening while wearing a biohazard containment suit, you will get “infected” by the friendly bacteria in the soil.
Want to level up your benefits? Grow your own food, and you’ll get it that way, too (yes, even if you wash and cook it)
❝I’d like to read articles on gut health and anxiety❞
We hope you caught yesterday’s edition of 10almonds, which touched on both of those! Other past editions you might like include:
We’ll be sure to include more going forward, too!

Dr. Suzanne Steinbaum’s Heart Book – by Dr. Suzanne Steinbaum
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 book is divided into three parts:
- What you should know
- What you should do
- All about you
This is a very useful format, since it lays out all the foundational knowledge, before offering practical advice and “how to” explanations, before finally wrapping up with personalizing things.
The latter is important, because while our basic risk factors can be assembled in a few lines of data (age, sex, race, genes, diet, exercise habits, etc) there’s a lot more to us than that, and oftentimes the data that doesn’t make the cut, makes the difference. Hormones on high on this list; we can say that a person is a 65-year-old woman and make a guess, but that’s all it is: a guess. Very few of us are the “average person” that statistical models represent accurately. And nor are social and psychological factors irrelevant; in fact often they are deciding factors!
So, it’s important to be able to look at ourselves as the whole persons we are, or else we’ll get a heart-healthy protocol that works on paper but actually falls flat in application, because the mathematical model didn’t take into account that lately we have been very stressed about such-and-such a thing, and deeply anxious about so-and-so, and a hopefully short-term respiratory infection has reduced blood oxygen levels, and all these kinds of things need to be taken into account too, for an overall plan to work.
The greatest strength of this book is that it attends to that.
The style of the book is a little like a long sales pitch (when all that’s being sold, by the way, is the ideas the book is offering; she wants you to take her advice with enthusiasm), but there’s plenty of very good information all the way through, making it quite worth the read.
Bottom line: if you’re a woman and/or love at least one woman, then you can benefit from this important book for understanding heart health that’s not the default.

The Vagus Nerve (And How You Can Make Use Of It)
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 Vagus Nerve: The Brain-Gut Highway
The longest cranial nerve is the vagus nerve; it runs all the way from your brain to your colon. It’s very important, and (amongst other tasks) it largely regulates your parasympathetic nervous system, and autonomous functions like:
- Breathing
- Heart rate
- Vasodilation & vasoconstriction
- Blood pressure
- Reflex actions (e.g. coughing, sneezing, swallowing, vomiting, hiccuping)
That’s great, but how does knowing about it help us?
Because of vagal maneuvers! This means taking an action to stimulate the vagus nerve, and prompt it to calm down various bodily functions that need calming down. This can take the form of:
- Massage
- Electrostimulation
- Diaphragmatic breathing
Massage is perhaps the simplest; “vagus” means “wandering”, and the nerve is accessible in various places, including behind the ears. That’s the kind of thing that’ easier to show than tell, though, so we’ll include a video at the end.
Electrostimulation is the fanciest, and has been used to treat migraines and cluster headaches. Check out, for example:
Update on noninvasive neuromodulation for migraine treatment-Vagus nerve stimulation
Diaphragmatic breathing means breathing from the diaphragm—the big muscular tissue that sits under your lungs. You might know it as “abdominal breathing”, and refers to breathing “to the abdomen” rather than merely to the chest.
Even though your lungs are obviously in your chest not your abdomen, breathing with a focus on expanding the abdomen (rather than the chest) when breathing in, will result in much deeper breathing as the diaphragm allows the lungs to fill downwards as well as outwards.
Why this helps when it comes to the vagus nerve is simply that the vagus nerve passes by the diaphragm, such that diaphragmatic breathing will massage the vagus nerve deep inside your body.
More than just treating migraines
Vagus nerve stimulation has also been researched and found potentially helpful for managing:
- Depression, inflammation, and heart disease
- Diabetes and glycemic issues in general
- Multiple sclerosis and autoimmune disease in general
- Alzheimer’s disease and dementia in general
- Rheumatoid arthritis (we already mentioned inflammation and autoimmune diseases, but this is an interesting paper so we included it)
All this is particularly important as we get older, because vagal response reduces with age, and vagus nerve stimulation, which improves vagal tone, makes it easier not just to manage the aforementioned maladies, but also simply to relax more easily and more deeply.

This Is When Your Muscles Are Strongest

Dr. Karyn Esser is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center, and she has insights to share on when it’s best to exercise:
It’s 4–5pm
Surprise, no clickbait or burying the lede!
This goes regardless of age or sex, but as we get older, it’s common for our circadian rhythm to weaken, which may result in a tendency to fluctuate a bit more.
However, since it’s healthy to keep one’s circadian rhythm as stable as reasonably possible, this is a good reason to try to keep our main exercise focused around that time of day, as it provides a sort of “anchor point” for the rest of our day to attach to, so that our body can know what time it is relative to that.
It’s also the most useful time of day to exercise, because most exercises give benefits proportional to progressive overloading, so training at our peak efficiency time will give the most efficient results. So much for those 5am runs!
On which note: while the title says “strongest” and the thumbnail has dumbbells, this does go for all different types of exercises that have been tested.

Strength training has a range of benefits for women. Here are 4 ways to get into weights
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.
Picture a gym ten years ago: the weights room was largely a male-dominated space, with women mostly doing cardio exercise. Fast-forward to today and you’re likely to see women of all ages and backgrounds confidently navigating weights equipment.
This is more than just anecdotal. According to data from the Australian Sports Commission, the number of women participating in weightlifting (either competitively or not) grew nearly five-fold between 2016 and 2022.
Women are discovering what research has long shown: strength training offers benefits beyond sculpted muscles.
Health benefits
Osteoporosis, a disease in which the bones become weak and brittle, affects more women than men. Strength training increases bone density, a crucial factor for preventing osteoporosis, especially for women negotiating menopause.
Strength training also improves insulin sensitivity, which means your body gets better at using insulin to manage blood sugar levels, reducing the risk of type 2 diabetes. Regular strength training contributes to better heart health too.
There’s a mental health boost as well. Strength training has been linked to reduced symptoms of depression and anxiety.
Improved confidence and body image
Unlike some forms of exercise where progress can feel elusive, strength training offers clear and tangible measures of success. Each time you add more weight to a bar, you are reminded of your ability to meet your goals and conquer challenges.
This sense of achievement doesn’t just stay in the gym – it can change how women see themselves. A recent study found women who regularly lift weights often feel more empowered to make positive changes in their lives and feel ready to face life’s challenges outside the gym.
Strength training also has the potential to positively impact body image. In a world where women are often judged on appearance, lifting weights can shift the focus to function.
Instead of worrying about the number on the scale or fitting into a certain dress size, women often come to appreciate their bodies for what they can do. “Am I lifting more than I could last month?” and “can I carry all my groceries in a single trip?” may become new measures of physical success.
Lifting weights can also be about challenging outdated ideas of how women “should” be. Qualitative research I conducted with colleagues found that, for many women, strength training becomes a powerful form of rebellion against unrealistic beauty standards. As one participant told us:
I wanted something that would allow me to train that just didn’t have anything to do with how I looked.
Society has long told women to be small, quiet and not take up space. But when a woman steps up to a barbell, she’s pushing back against these outdated rules. One woman in our study said:
We don’t have to […] look a certain way, or […] be scared that we can lift heavier weights than some men. Why should we?
This shift in mindset helps women see themselves differently. Instead of worrying about being objects for others to look at, they begin to see their bodies as capable and strong. Another participant explained:
Powerlifting changed my life. It made me see myself, or my body. My body wasn’t my value, it was the vehicle that I was in to execute whatever it was that I was executing in life.
This newfound confidence often spills over into other areas of life. As one woman said:
I love being a strong woman. It’s like going against the grain, and it empowers me. When I’m physically strong, everything in the world seems lighter.
Feeling inspired? Here’s how to get started
1. Take things slow
Begin with bodyweight exercises like squats, lunges and push-ups to build a foundation of strength. Once you’re comfortable, add external weights, but keep them light at first. Focus on mastering compound movements, such as deadlifts, squats and overhead presses. These exercises engage multiple joints and muscle groups simultaneously, making your workouts more efficient.
2. Prioritise proper form
Always prioritise proper form over lifting heavier weights. Poor technique can lead to injuries, so learning the correct way to perform each exercise is crucial. To help with this, consider working with an exercise professional who can provide personalised guidance and ensure you’re performing exercises correctly, at least initially.
3. Consistency is key
Like any fitness regimen, consistency is key. Two to three sessions a week are plenty for most women to see benefits. And don’t be afraid to occupy space in the weights room – remember you belong there just as much as anyone else.
4. Find a community
Finally, join a community. There’s nothing like being surrounded by a group of strong women to inspire and motivate you. Engaging with a supportive community can make your strength-training journey more enjoyable and rewarding, whether it’s an in-person class or an online forum.
Are there any downsides?
Gym memberships can be expensive, especially for specialist weightlifting gyms. Home equipment is an option, but quality barbells and weightlifting equipment can come with a hefty price tag.
Also, for women juggling work and family responsibilities, finding time to get to the gym two to three times per week can be challenging.
If you’re concerned about getting too “bulky”, it’s very difficult for women to bulk up like male bodybuilders without pharmaceutical assistance.
The main risks come from poor technique or trying to lift too much too soon – issues that can be easily avoided with some guidance.

Rebounding Into The Best Of Health
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.
“Trampoline” is a brand-name that’s been popularized as a generic name, and “rebounding”, the name used in this video, is the same thing as “trampolining”. With that in mind, let us bounce swiftly onwards:
Surprising benefits
It’s easy to think “isn’t that cheating?” to the point that such “cheating” could be useless, since surely the device is doing most of the work?
The thing is, while indeed it’s doing a lot of the work for you, your muscles are still doing a lot—mostly stabilization work, which is of course a critical thing for our muscles to be able to do. While it’s rare that we need to do a somersault in everyday life, it’s common that we have to keep ourselves from falling over, after all.
It also represents a kind of gentle resistance exercise, and as such, improves bone density—something first discovered during NASA research for astronauts. Other related benefits pertain to the body’s ability to deal with acceleration and deceleration; it also benefits the lymphatic system, which unlike the blood’s circulatory system, has no pump of its own. Rebounding does also benefit the cardiovascular system, though, as now the heart gets confused (in the healthy way, a little like it gets confused with high-intensity interval training).
Those are the main evidence-based benefits; anecdotally (but credibly, since these things can be said of most exercise) it’s also claimed that it benefits posture, improves sleep and mood, promotes weight loss and better digestion, reduces bloating, improves skin (the latter being due to improved circulation), and alleviates arthritis (most moderate exercise improves immune response, and thus reduces chronic inflammation, so again, this is reasonable, even if anecdotal).
