7 Keys To Healthy Longevity
This is Dr. Luigi Fontana. He’s a research professor of Geriatrics & Nutritional Science, and co-director of the Longevity Research Program at Washington University in St. Louis.
What does he want us to know?
He has a many-fold approach to healthy longevity, most of which may not be news to you, but you might want to prioritize some things:
Consider caloric restriction with optimal nutrition (CRON)
This is about reducing the metabolic load on your body, which frees up bodily resources for keeping yourself young.
Keeping your body young and healthy is your body’s favorite thing to do, but it can’t do that if it never gets a chance because of all the urgent metabolic tasks you’re giving it.
If CRON isn’t your thing (isn’t practicable for you, causes undue suffering, etc) then intermittent fasting is a great CR mimetic, and he recommends that too. See also:
- Is Cutting Calories The Key To Healthy Long Life?
- Fasting Without Crashing? We Sort The Science From The Hype
Keep your waistline small
Whichever approach you prefer to use to look after your metabolic health, keeping your waistline down is much more important for health than BMI.
Specifically, he recommends keeping it:
- under 31.5” for women
- under 37” for men
The disparity here is because of hormonal differences that influence both metabolism and fat distribution.
Exercise as part of your lifestyle
For Dr. Fontana, he loves mountain-biking (this writer could never!) and weight-lifting (also not my thing). But what’s key is not the specifics, but what’s going on:
- Some kind of frequent movement
- Some kind of high-intensity interval training
- Some kind of resistance training
Frequent movement because our bodies are evolved to be moving more often than not:
The Doctor Who Wants Us To Exercise Less, & Move More
High-Intensity Interval Training because unlike most forms of exercise (which slow metabolism afterwards to compensate), it boosts metabolism for up to 2 hours after training:
How To Do HIIT (Without Wrecking Your Body)
Resistance training because strength (of muscles and bones) matters too:
Resistance Is Useful! (Especially As We Get Older)
Writer’s examples:
So while I don’t care for mountain-biking or weight-lifting, what I do is:
1) movement: walk (briskly!) everywhere and also use a standing desk
2) HIIT: 2-minute bursts of hindu squats and/or exercise bike sprints
3) resistance: pilates and other calisthenics
Moderation is not key
Dr. Fontana advises that we do not smoke, and that we do not drink alcohol, for example. He also notes that just as the only healthy amount of alcohol is zero, less ultra-processed food is always better than more.
Maybe you don’t want to abstain completely, but mindful wilful consumption of something unhealthy is preferable to believing “moderate consumption is good for the health” and an unhealthy habit develops!
Greens and beans
Shocking absolutely nobody, Dr. Fontana advocates for (what has been the most evidence-based gold standard of healthy-aging diets for quite some years now) the Mediterranean diet.
See also: Four Ways To Upgrade The Mediterranean Diet ← this is about tweaking the Mediterranean diet per personal area of focus, e.g. anti-inflammatory bonus, best for gut, heart healthiest, and most neuroprotective.
Take it easy
Dr. Fontana advises us (again, with a wealth of evidence) Mindfulness-Based Stress Reduction, and to get good sleep.
Not shocked?
To quote the good doctor,
❝There are no shortcuts. No magic pills or expensive procedures can replace the beneficial effects of a healthy diet, exercise, mindfulness, or a regenerating night’s sleep.❞
Always a good reminder!

The Seven Principles for Making Marriage Work – by Dr. John Gottman
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.
A lot of relationship advice can seem a little wishy-washy. Hardline clinical work, on the other hand, can seem removed from the complex reality of married life. Dr. Gottman, meanwhile, strikes a perfect balance.
He looks at huge datasets, and he listens to very many couples. He famously isolated four relational factors that predict divorce with 91% accuracy, his “Four Horsemen”:
- Criticism
- Contempt
- Defensiveness
- Stonewalling
He also, as the title of this book promises (and we get a chapter-by-chapter deep-dive on each of them) looks at “Seven principles for making marriage work”. They’re not one-word items, so including them here would take up the rest of our space, and this is a book review not a book summary. However…
Dr. Gottman’s seven principles are, much like his more famous “four horsemen”, deeply rooted in science, while also firmly grounded in the reality of individual couples. Essentially, by listening to very many couples talk about their relationships, and seeing how things panned out with each of them in the long-term, he was able to see what things kept on coming up each time in the couples that worked out. What did they do differently?
And, that’s the real meat of the book. Science yes, but lots of real-world case studies and examples, from couples that worked and couples that didn’t.
In so doing, he provides a roadmap for couples who are serious about making their marriage the best it can be.
Bottom line: this is a must-have book for couples in general, no matter how good or bad the relationship.
- For some it’ll be a matter of realising “You know what; this isn’t going to work”
- For others, it’ll be a matter of “Ah, relief, this is how we can resolve that!”
- For still yet others, it’ll be a matter of “We’re doing these things right; let’s keep them forefront in our minds and never get complacent!”
- And for everyone who is in a relationship or thinking of getting into one, it’s a top-tier manual.

It’s Q&A Day at 10almonds!
Q: I would be interested in learning more about collagen and especially collagen supplements/powders and of course if needed, what is the best collagen product to take. What is collagen? Why do we need to supplement the collagen in our body? Thank you PS love the information I am receiving in the news letters. Keep it up
We’re glad you’re enjoying them! Your request prompted us to do our recent Research Review Monday main feature on collagen supplementation—we hope it helped, and if you’ve any more specific (or other) question, go ahead and let us know! We love questions and requests
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!
Q: Can you let us know about more studies that have been done on statins? Are they really worth taking?
That is a great question! We imagine it might have been our recent book recommendation that prompted it? It’s quite a broad question though, so we’ll do that as a main feature in the near future!
Q: Is MSG healthier than salt in terms of sodium content or is it the same or worse?
Great question, and for that matter, MSG itself is a great topic for another day. But your actual question, we can readily answer here and now:
- Firstly, by “salt” we’re assuming from context that you mean sodium chloride.
- Both salt and MSG do contain sodium. However…
- MSG contains only about a third of the sodium that salt does, gram-for-gram.
- It’s still wise to be mindful of it, though. Same with sodium in other ingredients!
- Baking soda contains about twice as much sodium, gram for gram, as MSG.
Wondering why this happens?
Salt (sodium chloride, NaCl) is equal parts sodium and chlorine, by atom count, but sodium’s atomic mass is lower than chlorine’s, so 100g of salt contains only 39.34g of sodium.
Baking soda (sodium bicarbonate, NaHCO₃) is one part sodium for one part hydrogen, one part carbon, and three parts oxygen. Taking each of their diverse atomic masses into account, we see that 100g of baking soda contains 27.4g sodium.
MSG (monosodium glutamate, C₅H₈NO₄Na) is only one part sodium for 5 parts carbon, 8 parts hydrogen, 1 part nitrogen, and 4 parts oxygen… And all those other atoms put together weigh a lot (comparatively), so 100g of MSG contains only 12.28g sodium.
Q: Thanks for the info about dairy. As a vegan, I look forward to a future comment about milk alternatives
Thanks for bringing it up! What we research and write about is heavily driven by subscriber feedback, so notes like this really help us know there’s an audience for a given topic!
We’ll do a main feature on it, to do it justice. Watch out for Research Review Monday!

Wildfires ignite infection risks, by weakening the body’s immune defences and spreading bugs in smoke
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.
Over the past several days, the world has watched on in shock as wildfires have devastated large parts of Los Angeles.
Beyond the obvious destruction – to landscapes, homes, businesses and more – fires at this scale have far-reaching effects on communities. A number of these concern human health.
We know fire can harm directly, causing injuries and death. Tragically, the death toll in LA is now at least 24.
But wildfires, or bushfires, can also have indirect consequences for human health. In particular, they can promote the incidence and spread of a range of infections.
Effects on the immune system
Most people appreciate that fires can cause burns and smoke inhalation, both of which can be life-threatening in their own right.
What’s perhaps less well known is that both burns and smoke inhalation can cause acute and chronic changes in the immune system. This can leave those affected vulnerable to infections at the time of the injury, and for years to come.
Burns induce profound changes in the immune system. Some parts go into overdrive, becoming too reactive and leading to hyper-inflammation. In the immediate aftermath of serious burns, this can contribute to sepsis and organ failure.
Other parts of the immune system appear to be suppressed. Our ability to recognise and fight off bugs can be compromised after sustaining burns. Research shows people who have experienced serious burns have an increased risk of influenza, pneumonia and other types of respiratory infections for at least the first five years after injury compared to people who haven’t experienced burns.
Wildfire smoke is a complex mixture containing particulate matter, volatile organic compounds, ozone, toxic gases, and microbes. When people inhale smoke during wildfires, each of these elements can play a role in increasing inflammation in the airways, which can lead to increased susceptibility to respiratory infections and asthma.
Research published after Australia’s Black Summer of 2019–20 found a higher risk of COVID infections in areas of New South Wales where bushfires had occurred weeks earlier.
We need more research to understand the magnitude of these increased risks, how long they persist after exposure, and the mechanisms. But these effects are thought to be due to sustained changes to the immune response.
Microbes travel in smoky air
Another opportunity for infection arises from the fire-induced movement of microbes from niches they usually occupy in soils and plants in natural areas, into densely populated urban areas.
Recent evidence from forest fires in Utah shows microbes, such as bacteria and fungal spores, can be transported in smoke. These microbes are associated with particles from the source, such as burned vegetation and soil.
There are thousands of different species of microbes in smoke, many of which are not common in background, non-smoky air.
Only a small number of studies on this have been published so far, but researchers have shown the majority of microbes in smoke are still alive and remain alive in smoke long enough to colonise the places where they eventually land.
How far specific microbes can be transported remains an open question, but fungi associated with smoke particles have been detected hundreds of miles downwind from wildfires, even weeks after the fire.
So does this cause human infections?
A subset of these airborne microbes are known to cause infections in humans.
Scientists are probing records of human fungal infections in relation to wildfire smoke exposure. In particular, they’re looking at soil-borne infectious agents such as the fungi Coccidioides immitis and Coccidioides posadasii which thrive in dry soils that can be picked up in dust and smoke plumes.
These fungi cause valley fever, a lung infection with symptoms that can resemble the flu, across arid western parts of the United States.
A study of wildland firefighters in California showed high rates of valley fever infections, which spurred occupational health warnings including recommended use of respirators when in endemic regions.
A California-based study of the wider population showed a 20% increase in hospital admissions for valley fever following any amount of exposure to wildfire smoke.
However, another found only limited evidence of excess cases after smoke exposure in wildfire-adjacent populations in California’s San Joaquin Valley.
These contrasting results show more research is needed to evaluate the infectious potential of wildfire smoke from this and other fungal and bacterial causes.
Staying safe
Much remains to be learned about the links between wildfires and infections, and the multiple pathways by which wildfires can increase the risk of certain infections.
There’s also a risk people gathering together after a disaster like this, such as in potentially overcrowded shelters, can increase the transmission of infections. We’ve seen this happen after previous natural disasters.
Despite the gaps in our knowledge, public health responses to wildfires should encompass infection prevention (such as through the provision of effective masks) and surveillance to enable early detection and effective management of any outbreaks.

Top 8 Fruits That Prevent & Kill Cancer
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.
Dr. Amy Dee, pharmacist and cancer survivor herself, lays out the best options for anticancer fruits:
The fruits
Without further ado, they are:
- Kiwi: promotes cancer cell death while sparing healthy cells
- Plums & peaches: an interesting choice to list these similar fruits together as one item, but they both also induce cell death in cancer cells while sparing healthy ones
- Dragon fruit: this does the same, while also inhibiting cancer cell growth
- Figs: these have antitumor effects specifically, while removing carcinogens too, and additionally sensitizing cancer cells to light therapy
- Cranberries: disrupt cancer cell adhesion, breaking down tumors, while protecting non-cancerous cells against DNA damage
- Citrus fruits: inhibit tumor growth and kill cancer cells; regular consumption is also associated with a lower cancer risk (be warned though, grapefruit interacts with some medications)
- Cherries: induce cancer cell death; protect healthy cells against DNA damage
- Tomatoes: don’t often make it into lists of fruits, but lycopene reduces cancer risk, and slows the growth of cancer cells (10almonds note: watermelon has more lycopene than tomatoes, and is more traditionally considered a fruit in all respects, so could have taken the spot here).
We would also argue that apricots could have had a spot on the list, both for their lycopene content (comparable to tomatoes) and their botanical (and thus phytochemical) similarities to peaches and plums.
For more information on each of these (she also talks about the different polyphenols and other nutrients that constitute the active compounds delivering these anticancer effects), enjoy:

Think Again – by Adam Grant
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.
Warning: this book may cause some feelings of self-doubt! Ride them out and see where they go, though.
It was Socrates who famously (allegedly) said “ἓν οἶδα ὅτι οὐδὲν οἶδα”—”I know that I know nothing”.
Adam Grant wants us to take this philosophy and apply it usefully to modern life. How?
The main premise is that rethinking our plans, answers and decisions is a good thing… Not a weakness. In contrast, he says, a fixed mindset closes us to opportunities—and better alternatives.
He wants us to be sure that we don’t fall into the trap of the Dunning-Kruger Effect (overestimating our abilities because of being unaware of how little we know), but he also wants us to rethink whole strategies, too. For example:
Grant’s approach to interpersonal conflict is very remniscent of another book we might review sometime, “Aikido in Everyday Life“. The idea here is to not give in to our knee-jerk responses to simply retaliate in kind, but rather to sidestep, pivot, redirect. This is, admittedly, the kind of “rethinking” that one usually has to rethink in advance—it’s too late in the moment! Hence the value of a book.
Nor is the book unduly subjective. “Wishy-washiness” has a bad rep, but Grant gives us plenty in the way of data and examples of how we can, for example, avoid losses by not doubling down on a mistake.
What, then, of strongly-held core principles? Rethinking doesn’t mean we must change our mind—it simply means being open to the possibility in contexts where such makes sense.
Grant borrows, in effect, from:
❝Do the best you can until you know better. Then when you know better… do better!❞
So, not so much undercutting the principles we hold dear, and instead rather making sure they stand on firm foundations.
All in all, a thought-provokingly inspiring read!
