The Real Immune-Boosters
What comes to your mind when we say “immune support”? Vitamin C and maybe zinc? Those have their place, but there are things we can do that are a lot more important!
It’s just, these things are not talked about as much, because stores can’t sell them to you
Sleep
One of the biggest difference-makers. Get good sleep! Getting at least 7 hours decent sleep (not lying in bed, not counting interruptions to sleep as part of the sleep duration) can improve your immune system by three or four times.
Put another way, people are 3–4 times more likely to get sick if they get less sleep than that on average.

Eat an anti-inflammatory diet
In short, for most of us this means lots of whole plant foods (lots of fiber), and limited sugar, flour, alcohol.
For more details, you can see our main feature on this: Keep Inflammation At Bay!
You may wonder why eating to reduce inflammation (inflammation is a form of immune response) will help improve immune response. Put it this way:
If your town’s fire service is called out eleventy-two times per day to deal with things that are not, in fact, fires, then when there is a fire, they will be already exhausted, and will not do their job so well.
Look after your gut microbiota
Additionally, healthy gut microbiota (fostered by the same diet we just described) help keep your body pathogen-free, by avoiding “leaky gut syndrome” that occurs when, for example, C. albicans (you do not want this in your gut, and it thrives on the things we just told you to avoid) puts its roots through your intestinal walls, making holes in them. And through those holes? You definitely do not want bacteria from your intestines going into the rest of your body.

Actually get that moderate exercise
There’s definitely a sweet-spot here, because too much exercise will also exhaust you and deplete your body’s resources. However, the famous “150 minutes per week” (so, a little over 20 minutes per day, or 25 minutes per day with one day off) will make a big difference.
See: Exercise and the Regulation of Immune Functions
Manage your stress levels (good and bad!)
This one swings both ways:
- Acute stress (like a cold shower) is good for immune response. Think of it like a fire drill for your body.
- Chronic stress (“the general everything” persistently stressful in life) is bad for immune response. This is the fire drill that never ends. Your body’s going to know what to do really well, but it’s going to be exhausted already by the time an actual threat hits.

Supplement, yes.
These are far less critical than the above things, but are also helpful. Good things to take include:
Enjoy, and stay well!

Avocado, Coconut & Lime Crumble Pots
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.
This one’s a refreshing snack or dessert, whose ingredients come together to make a very good essential fatty acid supplement. Coconut is a good source of MCTs, avocados are rich in omega 3, 6, and 9, while chia seeds are a great ALA omega 3 food, topping up the healthy balance.
You will need
- flesh of 2 large ripe avocados
- grated zest and juice of 2 limes
- 3 tbsp coconut oil
- 1 tbsp chia seeds
- 2 tsp honey (omit if you prefer a less sweet dish)
- 1 tsp desiccated coconut
- 4 low-sugar oat biscuits
Method
(we suggest you read everything at least once before doing anything)
1) Blend the avocado, lime juice, coconut oil, honey, and half the desiccated coconut, in a food processor.
2) Scoop the mixture into 4 ramekins (or equivalent-sized glasses), making sure to leave a ½” gap at the top. Refrigerate for at least 2–4 hours (longer is fine if you’re not ready to serve yet).
3) Assemble, by crumbling the oat biscuits and sprinkling on top of each serving, along with the other half of the desiccated coconut, the lime zest, and the chia seeds.
4) Serve immediately:
Enjoy!

Is Your Gut Leading You Into Osteoporosis?
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.
Bacterioides Vulgatus & Bone Health
We’ve talked before about the importance of gut health:
And we’ve shared quite some information and resources on osteoporosis:
- The Bare-bones Truth: Osteoporosis Mythbusting
- Osteoporosis Exercises (What To Do, And What To Avoid)
- Vit D + Calcium: Too Much Of A Good Thing?
- Collagen For Bones: We Are Such Stuff As Fish Are Made Of
- Which Osteoporosis Medication, If Any, Is Right For You?
How the two are connected
A recent study looked at Bacterioides vulgatus, a very common gut bacterium, and found that it suppresses the gut’s production of valeric acid, a short-chain fatty acid that enhances bone density:
❝For the study, researchers analyzed the gut bacteria of more than 500 peri- and post-menopausal women in China and further confirmed the link between B. vulgatus and a loss of bone density in a smaller cohort of non-Hispanic White women in the United States.❞
Pop-sci source: Does gut bacteria cause osteoporosis?
The study didn’t stop there, though. They proceeded to test, with a rodent model, the effect of giving them either:
- more B. vulgatus, or
- valeric acid supplements
The results of this were as expected:
- Those who were given more B. vulgatus got worse bone microstructure
- Those who were given valeric acid supplements got stronger bones overall
Study source: Gut microbiota impacts bone via Bacteroides vulgatus-valeric acid-related pathways
Where can I get valeric acid?
We couldn’t find a handy supplement for this, but it is in many foods, including avocados, blueberries, cocoa beans, and an assortment of birds.
Click here to see a more extensive food list (you’ll need to scroll down a little)
Bonus: if you happen to be on HRT in the form of Estradiol valerate (e.g: Progynova), then that “valerate” is an ester of valeric acid, that your body can metabolize and use as such.
Enjoy!

Just One Thing – by Dr. Michael Mosley
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.
This is a collection of easy-to-implement changes that have good science behind them to show how they can benefit us. Some things are obvious (e.g: drink water); others, less so (e.g: sing, to reduce inflammation).
The book is divided thematically into times of the day, though in many cases it’s not a hard rule that a thing needs to be done at a certain time. Others are, like a cold shower in the morning and hot bath before bed—you might not want to switch those around!
The style is very pop-science, and does not have in-line citations for claims, but it does have a bibliography in the bag organized by each “one thing”, e.g. it might say “get some houseplants” and then list a number of references supporting that, with links to the studies showing how that helps. For those with the paper version, don’t worry, you can copy the URL from the book into your browser and see it that way. In any case, there are 2–6 scientific references for each claim, which is very respectable for a pop-sci book.
Bottom line: if you’re looking for evidence-based “one little thing” changes that can make a big difference, this book has lots!

52 Small Changes – by Brett Blumenthal
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.
We see a lot of books that exhort us to get a six-pack in a month, change our life in 7 days, learn Japanese in 24 hours. The reality is, things take time!
Brett Blumenthal is more realistic while being just as motivational:
The idea is simple… Make one small change per week for 52 weeks, and at the end of the year, you’ll be healthier and happier.
At 10almonds, we’re big fans of small changes that add up (or rather: compound!) to make big differences, so this one’s absolutely our style!
Best of all, she offers us not just “do this” advice, but also “and here’s the information and resources you’ll need to make this change work the best it can for you”
The advices range in topic from nutrition to exercise to sleep to mental wellness to interpersonal stuff and more. The biggest focus is on personal health, though, with small changes to exercise and nutrition making up the lion’s share of the changes.
Bottom line: this is a book you’ll want to grab once a week. Consider setting a reminder on your phone to check in with it each Sunday, for example!

Signs Of Low Estrogen In Women: What Your Skin, Hair, & Nails Are Trying To Tell You
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.
Skin, hair, and nails are often thought of purely as a beauty thing, but in fact they can be indicative of a lot of other aspects of health. Dr. Andrea Suarez takes us through some of them in this video about the systemic (i.e., whole-body, not just related to sex things) effects of estrogen, and/or a deficiency thereof.
Beyond the cosmetic
Low estrogen levels are usual in women during and after untreated menopause, resulting in various changes in the skin, hair, and nails, that reflect deeper issues, down to bone health, heart health, brain health, and more. Since we can’t see our bones or hearts or brains without scans (or a serious accident/incident), we’re going to focus on the outward signs of estrogen deficiency.
Estrogen helps maintain healthy collagen production, skin elasticity, wound healing, and moisture retention, making it essential for youthful and resilient skin. Declining estrogen levels with menopause lead to a thinner epidermis, decreased collagen production, and more pronounced wrinkles. Skin elasticity also diminishes, which slows the skin’s ability to recover from stretching or deformation. Wound healing also becomes slower, increasing the risk of infections and extended recovery periods after injuries or surgeries—bearing in mind that collagen is needed in everything from our skin to our internal connective tissue (fascia) and joints and bones. So all those things are going to struggle to recover from injury (and surgery is also an injury) without it.
Other visible changes associated with declining estrogen include significant dryness as a result of reduced hyaluronic acid and glycosaminoglycan production, which are essential for moisture retention. The skin becomes more prone to irritation and increased water loss. Additionally, estrogen deficiency results in less resistance to oxidative stress, making the skin more susceptible to damage from environmental factors such as UV radiation and pollution, as well as any from-the-inside pollution that some may have depending on diet and lifestyle.
Acne and enlarged pores are associated with increased testosterone, but testosterone and estrogen are antagonistic in most ways, and in this case a decrease in estrogen will do the same, due increased unopposed androgen signaling affecting the oil glands. The loss of supportive collagen also causes the skin around pores to lose structure, making them appear larger. The reduction in skin hydration further exacerbates the visibility of pores and can contribute to the development of blackheads due to abnormal cell turnover.
Blood vessel issues tend to arise as estrogen levels drop, leading to a reduction in angiogenesis, i.e. the formation and integrity of blood vessels. This results in more fragile and leaky blood vessels, making the skin more prone to bruising, especially on areas frequently exposed to the sun, such as the backs of the hands. This weakened vasculature also further contributes to the slower wound healing that we talked about, due to less efficient delivery of growth factors.
Hair and nail changes often accompany estrogen deficiency. Women may notice hair thinning, increased breakage, and a greater likelihood of androgenic alopecia. The texture of the hair can change, becoming more brittle. Similarly, nails can develop ridges, split more easily, and become more fragile due to reduced collagen and keratin production, which also affects the skin around the nails.
As for what to do about it? Management options for estrogen-deficient skin include:
- Bioidentical hormone replacement therapy (HRT), which can improve skin elasticity, boost collagen production, and reduce dryness and fragility, as well as addressing the many more serious internal things that are caused by the same deficiency as these outward signs.
- Low-dose topical estrogen cream, which can help alleviate skin dryness and increase skin strength, won’t give the systemic benefits (incl. to bones, heart, brain, etc) that only systemic HRT can yield.
- Plant-based phytoestrogens, which are not well-evidenced, but may be better than nothing if nothing is your only other option. However, if you are taking anything other form of estrogen, don’t use phytoestrogens as well, or they will compete for estrogen receptors, and do the job not nearly so well while impeding the bioidentical estrogen from doing its much better job.
And for all at any age, sunscreen continues to be one of the best things to put on one’s skin for general skin health, and this is even more true if running low on estrogen.

Tips for Avoiding PFAs
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
❝Hi, do you have anything helpful on avoiding PFAs?❞
PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are “forever chemicals” made specifically to avoid degradation of industrial and chemical products. Which is great for providing stain and water resistance, but not so great for our bodies or the environment.
To go into all the harms they cause would take a main feature (maybe we will, one of these days), but suffice it to say, they’re not good, and range from cancer and insulin resistance to hypertension and reduced immune response.
To answer your question in a nutshell, avoiding them completely would be almost impossible, but we can reduce our exposure a lot by avoiding single-use food/drink products that have been waterproofed, e.g. paper/bamboo straws, utensils, cups, dishes, take-out containers, etc.
Also, anything advertised as “stain-resistant” that you suspect should be quite stainable by nature, is probably good to avoid too.
For more detailed information than we have room for here today, here’s a helpful overview:
