Dr. Sharon Bergquist gives us a tour:
Stress, from the inside out
Stress is a natural physical and emotional response to challenges or being overwhelmed. It can be beneficial in short-term situations (e.g. escape from a tiger) but is harmful when prolonged or frequent (e.g. escape the rat-race).
Immediate physiological response: cortisol, adrenaline (epinephrine), and norepinephrine are released by the adrenal glands.
The effects this has (non-exhaustive list; we’re just citing what’s in the video here):
- Cortisol impairs blood vessel function, promoting atherosclerosis.
- Adrenaline increases heart rate and blood pressure, leading to hypertension.
- Stress disrupts the brain-gut connection, causing:
- Digestive issues like irritable bowel syndrome and heartburn.
- Changes in gut bacteria composition, potentially affecting overall health.
- Cortisol increases appetite and cravings for energy-dense “comfort foods”.
- This in turn promotes visceral fat storage, which raises the risk of heart disease and insulin resistance.
- Immune-specific effects:
- Stress hormones initially aid in healing and immune defense.
- Chronic stress weakens immune function (by over-working it constantly), increasing susceptibility to infections and slowing recovery.
- Other systemic effects:
- Chronic stress shortens telomeres, which protect chromosomes. Shortened telomeres accelerate cellular aging.
- Chronic stress can also cause acne, hair loss, sexual dysfunction, headaches, muscle tension, fatigue, irritability, and difficulty concentrating.
So, how to manage this? The video says that viewing stressful situations as controllable challenges, rather than insurmountable threats, leads to better short-term performance and long-term health.
Which would be wonderful, except that usually things are stressful precisely because they are not entirely within the field of our control, and the usual advice is to tend to what we can control, and accept what we can’t.
However… That paradigm still leaves out the very big set of “this might be somewhat within our control or it might not; we really don’t know yet; we can probably impact it but what if we don’t do enough, or take the wrong approach and do the wrong thing? And also we have 17 competing stressors, which ones should we prioritize tending to first, and…” and so on.
To that end, we suggest checking out the “Want to learn more?” link we drop below the video today, as it is about managing stress realistically, in a world that, if we’re honest about it, can sometimes be frankly unmanageable.

I lost weight and my period stopped. How are weight and menstruation linked?
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.
You may have noticed that changes in weight are sometimes accompanied by changes in your period.
But what does one really have to do with the other?
Maintaining a healthy weight is key to regular menstruation. Here’s why – and when to talk to your doctor.
The role of hormones
The menstrual cycle – including when you bleed and ovulate – is regulated by a balance of hormones, particularly oestrogen.
The ovaries are connected to the brain through a hormonal signalling system. This acts as a kind of “chain of command” of hormones controlling the menstrual cycle.
The brain produces a key hormone, called the gonadotropin-releasing hormone, in the hypothalamus. It stimulates the release of other hormones which tell the ovaries to produce oestrogen and release a mature egg (ovulation).
But the release of the gonadotropin-releasing hormone depends on oestrogen levels and how much energy is available to the body. Both of these are closely related to body weight.
Oestrogen is primarily produced in the ovaries, but fat cells also produce oestrogen. This is why weight – and more specifically body fat – can affect menstruation.
Fat cells produce oestrogen, a hormone with a key role in the menstrual cycle. Halfpoint/Shutterstock Can being underweight affect my period?
The body prioritises conserving energy. When reserves are low it stops anything non-essential, such as reproduction.
This can happen when you are underweight, or suddenly lose weight. It can also happen to people who undertake intense exercise or have inadequate nutrition.
The stress sends the hypothalamus into survival mode. As a result, the body lowers its production of the hormones important to ovulation, including oestrogen, and stops menstruation.
Being chronically underweight means not having enough energy available to support reproduction, which can lead to menstrual irregularities including amenorrhea (no periods at all).
This results in very low oestrogen levels and can cause potentially serious health risks, including infertility and bone loss.
Missing periods is not always a cause for concern. But a chronic lack of energy availability can be, if not addressed. The two are linked, meaning understanding your period and being aware of any prolonged changes is important.
How about being overweight?
Higher body fat can elevate oestrogen levels.
When you’re overweight your body stores extra energy in fat cells, which produce oestrogen and other hormones and can cause inflammation in the body. So, if you have a lot of fat cells, your body produces an excess of these hormones. This can affect normal functioning of the uterus lining (endometrium).
Excess oestrogen and inflammation can interfere in the feedback system to the brain and stop ovulation. As a result, you may have irregular or missed periods.
It can also lead to pain (dysmenorrhea) and heavier bleeding (menorrhagia).
Being overweight can sometimes worsen premenstrual syndrome as well. One study found for every 1 kg increase in height (m²) in body mass index (BMI), the risk of premenstrual syndrome went up by 3%. Women with a BMI over 27.5 kg/m² had a much higher risk than those with a BMI under 20 kg/m².
What else might be going on?
Sometimes weight changes are linked to hormonal balances that indicate an underlying condition.
For example, people with polycystic ovary syndrome may gain weight or find it hard to lose weight because they have a hormonal imbalance, including higher levels of testosterone.
The syndrome is also associated with irregular periods and heavy bleeding. So, if you notice these symptoms, it’s a good idea to talk to your doctor.
Similarly, weight changes and irregular periods in midlife might signal the start of perimenopause, the period before menopause (when your periods stop altogether).
Changes in weight and your period could be a sign of menopause approaching. Sabrina Bracher/Shutterstock When should I worry?
Small changes in when your period comes or how long it lasts are usually harmless.
Similarly, slight fluctuations in weight won’t usually have a significant impact on your period – or the changes may be so subtle you don’t notice them.
But regular menstruation is an important marker of female health. Sometimes changes in flow, regularity or the pain you experience can indicate there’s something else going on.
If you notice changes and they don’t feel right to you, speak to a health care provider.

Type 2 Diabetic Foot Problems
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!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
This newsletter has been growing a lot lately, and so have the questions/requests, and we love that! 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: I’d like to know more about type 2 diabetic foot problems
You probably know that the “foot problems” thing has less to do with the feet and more to do with blood and nerves. So, why the feet?
The reason feet often get something like the worst of it, is because they are extremities, and in the case of blood sugars being too high for too long too often, they’re getting more damage as blood has to fight its way back up your body. Diabetic neuropathy happens when nerves are malnourished because the blood that should be keeping them healthy, is instead syrupy and sluggish.
We’ll definitely do a main feature sometime soon on keeping blood sugars healthy, for both types of diabetes plus pre-diabetes and just general advice for all.
In the meantime, here’s some very good advice on keeping your feet healthy in the context of diabetes. This one’s focussed on Type 1 Diabetes, but the advice goes for both:

Tofu vs Seitan – Which is Healthier?
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.
Our Verdict
When comparing tofu to seitan, we picked the tofu.
Why?
This one is not close!
In terms of macros, seitan does have about 2x the protein, but it also has 6x the carbs and 6x the sodium of tofu, as well as less fiber than tofu.. So we’ll call it a tie on macros. But…
Seitan is also much more processed than tofu, as tofu has usually just been fermented and possibly pressed (depending on kind). Seitan, in contrast, is processed gluten that has been extracted from wheat and usually had lots of things happen to it on the way (depending on kind).
About that protein… Tofu is a complete protein, meaning it has all of the essential amino acids. Seitain, meanwhile, is lacking in lysine.
When it comes to vitamins and minerals, again tofu easily comes out on top; tofu has 5x the calcium, similar iron, more magnesium, 2x the phosphorous, 150% of the potassium, and contains several other nutrients that seitan doesn’t, such as folate and choline.
So, easy winning for tofu across the board on micronutrients.
Tofu is also rich in isoflavones, antioxidant phytonutrients, while seitan has no such benefits.
So, another win for tofu.
There are two reasons you might choose seitan:
- prioritizing bulk protein above all other health considerations
- you are allergic to soy and not allergic to gluten
If neither of those things are the case, then tofu is the healthier choice!

The Food Additive You Do Want
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.
Q: When Is A Fiber Not A Fiber?
A: when it’s a resistant starch. What’s it resistant to? Digestion. So, it functions as though a fiber, and by some systems, may get classified as such.
It’s a little like how sucralose is technically a sugar, but the body processes it like a fiber (but beware, because the sweetness of this disaccharide alone can trigger an insulin response anyway—dose dependent)
There may be other problems too:
But today’s not about sucralose, it’s about…
Guar gum’s surprising dietary role
You may have noticed “guar gum” on the list of ingredients of all kinds of things from baked goods to dairy products to condiments to confectionary and more.
It’s also used in cosmetics and explosives, but let’s not focus on that.
It’s used in food products as…
- a bulking agent
- a thickener
- a stabilizer
Our attention was caught by a new study, that found:
Resistant starch intake facilitates weight loss in humans by reshaping the gut microbiota
Often people think of “fiber helps weight loss” as “well yes, if you are bulking out your food with sawdust, you will eat less”, but it’s not that.
There’s an actual physiological process going on here!
We can’t digest it, but our gut microbiota can and will ferment it. See also:
Fiber against pounds: Resistant starch found to support weight loss
Beyond weight loss
Not everyone wants to lose weight, and even where weight loss is a goal, it’s usually not the only goal. As it turns out, adding guar gum into our diet does more things too:
Resistant starch supplement found to reduce liver triglycerides in people with fatty liver disease
(specifically, this was about NAFLD, non-alcoholic fatty liver disease)
Digging a little, it seems the benefits don’t stop there either:
Diet high in guar gum fiber limits inflammation and delays multiple sclerosis symptoms
(this one was a rodent study, but still, it’s promising and it’s consistent with what one would expect based on what else we know about its function in diet)
Should we just eat foods with guar gum in as an additive?
That depends on what they are, but watch out for the other additives if you do!
You can just buy guar gum by itself, by the way (here’s an example product on Amazon).
It’s doubtlessly no fun to take as a supplement (we haven’t tried this one), but it can be baked into bread, if baking’s your thing, or just used as a thickener in recipes where ordinarily you might use cornstarch or something else.
Can I get similar benefits from other foods?
The relevant quality is also present in resistant starches in general, so you might want to check out these foods, for example:

Build Strong Feet: Exercises To Strengthen Your Foot & Ankle
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 depends on the health of our feet, especially when it comes to their strength and stability. But they often get quite neglected, when it comes to maintenance. Here’s how to help your feet keep the rest of your body in good condition:
On a good footing
The foot-specific exercises recommended here include:
- Active toe flexion/extension: curl and extend your toes
- Active toe adduction/abduction: use a towel for feedback this time as you spread your toes
- “Short foot” exercise: create an arch by bringing the base of your big toe towards your heel
- Resisted big toe flexion: use resistance bands; flex your big toe while controlling the others.
- Standing big toe flexion (isometric): press your big toe against an inclined surface as forcefully as you can
- Foot bridge exercise: hold your position with the front part of your feet on an elevated surface, to strengthen the arch.
- Heel raises: which can be progressed from basic to more advanced variations, increasing difficulty
- Ankle movements: dorsiflexion, inversion, etc, to increase mobility
It’s important to also look after your general lower body strength and stability, including (for example) single-leg deadlifts, step-downs, and lunges
Balance and proprioceptive exercises are good too, such as a static or dynamic one-leg balances, progressing to doing them with your eyes closed and/or on unstable surfaces (be careful, of course, and progress to this only when confident).
For more on all of these, an explanation of the anatomy, some other exercises too, and visual demonstrations, enjoy:

Ultra-Processed People – by Dr. Chris van Tulleken
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 probably won’t come as a great surprise to any of our readers that ultra-processed food is—to make a sweeping generalization—not fabulous for the health. So, what does this book offer beyond that?
Perhaps this book’s greatest strength is in showing not just what ultra-processed foods are, but why they are. In principle, food being highly processed should be neither good nor bad by default. Much like GMOs, if a food is modified to be more nutritious, that should be good, right?
Only, that’s mostly not what happens. What happens instead is that food is modified (be it genetically or by ultra-processing) to be cheaper to produce, and thus maximise the profit margin.
The addition of a compound that increases shelf-life but harms the health, increases sales and is a net positive for the manufacturer, for instance. Dr. van Tulleken offers us many, many, examples and explanations of such cost-cutting strategies at our expense.
In terms of qualifications, the author has an MD from Oxford, and also a PhD, but the latter is in molecular virology; not so relevant here. Yet, we are not expected to take an “argument from authority”, and instead, Dr. van Tulleken takes great pains to go through a lot of studies with us—the good, the bad, and the misleading.
If the book has a downside, then this reviewer would say it’s in the format; it’s less a reference book, and more a 384-page polemic. But, that’s a subjective criticism, and for those who like that sort of thing, that is the sort of thing that they like.
