Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.
(this is in response to last week’s piece on lutein, eyes, and brain health)
We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:

Five Advance Warnings of Multiple Sclerosis

Five Advance Warnings of Multiple Sclerosis
First things first, a quick check-in with regard to how much you know about multiple sclerosis (MS):
- Do you know what causes it?
- Do you know how it happens?
- Do you know how it can be fixed?
If your answer to the above questions is “no”, then take solace in the fact that modern science doesn’t know either.
What we do know is that it’s an autoimmune condition, and that it results in the degradation of myelin, the “insulator” of nerves, in the central nervous system.
- How exactly this is brought about remains unclear, though there are several leading hypotheses including autoimmune attack of myelin itself, or disruption to the production of myelin.
- Treatments look to reduce/mitigate inflammation, and/or treat other symptoms (which are many and various) on an as-needed basis.
If you’re wondering about the prognosis after diagnosis, the scientific consensus on that is also “we don’t know”:
Read: Personalized medicine in multiple sclerosis: hope or reality?
this paper, like every other one we considered putting in that spot, concludes with basically begging for research to be done to identify biomarkers in a useful fashion that could help classify many distinct forms of MS, rather than the current “you have MS, but who knows what that will mean for you personally because it’s so varied” approach.
The Five Advance Warning Signs
Something we do know! First, we’ll quote directly the researchers’ conclusion:
❝We identified 5 health conditions associated with subsequent MS diagnosis, which may be considered not only prodromal but also early-stage symptoms.
However, these health conditions overlap with prodrome of two other autoimmune diseases, hence they lack specificity to MS.❞
So, these things are a warning, five alarm bells, but not necessarily diagnostic criteria.
Without further ado, the five things are:
- depression
- sexual disorders
- constipation
- cystitis
- urinary tract infections
❝This association was sufficiently robust at the statistical level for us to state that these are early clinical warning signs, probably related to damage to the nervous system, in patients who will later be diagnosed with multiple sclerosis.
The overrepresentation of these symptoms persisted and even increased over the five years after diagnosis.❞

Dr. Greger’s Daily Dozen
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.
Give Us This Day Our Daily Dozen
This is Dr. Michael Greger. He’s a physician-turned-author-educator, and we’ve featured him and his work occasionally over the past year or so:
- Brain Food? The Eyes Have It! ← this is about dark leafy greens, lutein, & avoiding Alzheimer’s
- Twenty-One, No Wait, Twenty Tweaks For Better Health ← he says 21, but we say one of them is very skippable. Check it out and decide what you think!
- Dr. Greger’s Anti-Aging Eight ← his top well-evidenced interventions specifically for slowing aging
But what we’ve not covered, astonishingly, is one of the things for which he’s most famous, which is…
Dr. Greger’s Daily Dozen
Based on the research in the very information-dense tome that his his magnum opus How Not To Die (while it doesn’t confer immortality, it does help avoid the most common causes of death), Dr. Greger recommends that we take care to enjoy each of the following things per day:
Beans
- Servings: 3 per day
- Examples: ½ cup cooked beans, ¼ cup hummus
Greens
- Servings: 2 per day
- Examples: 1 cup raw, ½ cup cooked
Cruciferous vegetables
- Servings: 1 per day
- Examples: ½ cup chopped, 1 tablespoon horseradish
Other vegetables
- Servings: 2 per day
- Examples: ½ cup non-leafy vegetables
Whole grains
- Servings: 3 per day
- Examples: ½ cup hot cereal, 1 slice of bread
Berries
- Servings: 1 per day
- Examples: ½ cup fresh or frozen, ¼ cup dried
Other fruits
- Servings: 3 per day
- Examples: 1 medium fruit, ¼ cup dried fruit
Flaxseed
- Servings: 1 per day
- Examples: 1 tablespoon ground
Nuts & (other) seeds
- Servings: 1 per day
- Examples: ¼ cup nuts, 2 tablespoons nut butter
Herbs & spices
- Servings: 1 per day
- Examples: ¼ teaspoon turmeric
Hydrating drinks
- Servings: 60 oz per day
- Examples: Water, green tea, hibiscus tea
Exercise
- Servings: Once per day
- Examples: 90 minutes moderate or 40 minutes vigorous
Superficially it seems an interesting choice to, after listing 11 foods and drinks, have the 12th item as exercise but not add a 13th one of sleep—but perhaps he quite reasonably expects that people get a dose of sleep with more consistency than people get a dose of exercise. After all, exercise is mostly optional, whereas if we try to skip sleep for too long, our body will force the matter for us.
Further 10almonds notes:
- We’d consider chia superior to flax, but you do you. Flax is a fine choice also.
- We recommend trying to get each of these top 5 most health-giving spices in daily if you can.
Enjoy!

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.

The Dental Diet – by Dr. Steven Lin
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.
As it turns out, there’s a lot more to healthy teeth than skipping the sugar and getting some calcium.
The author’s journey started with the realization that most of his work as a dentist should be unnecessary, and not just in the “you should have been flossing” sense. Rather, he came to the same conclusions as his fellow dentist Weston Price before him, and this time (unlike Price) he stuck to his own field, dentistry—meaning that the conclusions he kept were the more valid ones.
Another thing he does better than Price is that he contextualizes the information—we don’t need, for example, to be eating seal fat as a main component of our diet, but we do need to be getting sufficient amounts of certain fat-soluble vitamins. And most people aren’t. Same with what’s good or bad for our oral microbiome, and by extension, our saliva, and by extension, our teeth and gums.
There’s a lot of nutritional information in here; macros and micronutrients alike, but the book goes further than that, to also recommend minimally-processed food that requires more chewing, for example. Not just for its nutritional content, but because that helps our teeth move to (and then stay) where they are ideally supposed to be. No amount of perfectly-blended nutritional supplement drink will align your maxilla for you, say. But chomping on raw carrots? Different story.
Dr. Lin offers a 40-day meal plan, but aware that if you’re vegetarian or vegan you’re probably going to have to rethink it yourself using the information he gives, because his meal plan includes animal products.
Bottom line: if you’d like to eat for better oral health (nutritionally, physically, and for your oral microbiome), this book has all the information you’ll need.

Sun, Sea, And Sudden Killers To Avoid

Stay Safe From Heat Exhaustion & Heatstroke!
For most of us, summer is upon us now. Which can be lovely… and also bring new, different health risks. Today we’re going to talk about heat exhaustion and heatstroke.
What’s the difference?
Heat exhaustion is a milder form of heatstroke, but the former can turn into the latter very quickly if left untreated.
Symptoms of heat exhaustion include:
- Headache
- Nausea
- Cold sweats
- Light-headedness
Symptoms of heatstroke include the above and also:
- Red/flushed-looking skin
- High body temperature (104ºF / 40ºC)
- Disorientation/confusion
- Accelerated heart rate
Click here for a handy downloadable infographic you can keep on your phone
What should we do about it?
In the case of heatstroke, call 911 or the equivalent emergency number for the country where you are.
Hopefully we can avoid it getting that far, though:
Prevention first
Here are some top tips to avoid heat exhaustion and thus also avoid heatstroke. Many are common sense, but it’s easy to forget things—especially in the moment, on a hot sunny day!
- Hydrate, hydrate, hydrate
- (Non-sugary) iced teas, fruit infusions, that sort of thing are more hydrating than water alone
- Avoid alcohol
- If you really want to imbibe, rehydrate between each alcoholic drink
- Time your exercise with the heat in mind
- In other words, make any exercise session early or late in the day, not during the hottest period
- Use sunscreen
- This isn’t just for skin health (though it is important for that); it will also help keep you cooler, as it blocks the UV rays that literally cook your cells
- Keep your environment cool
- Shade is good, air conditioning / cooling fans can help.
- A wide-brimmed hat is portable shade just for you
- Wear loose, breathable clothing
- We write about health, not fashion, but: light breathable clothes that cover more of your body are generally better healthwise in this context, than minimal clothes that don’t, if you’re in the sun.
- Be aware of any medications you’re taking that will increase your sensitivity to heat.
- This includes medications that are dehydrating, and includes most anti-depressants, many anti-nausea medications, some anti-allergy medications, and more.
- Check your labels/leaflets, look up your meds online, or ask your pharmacist.
Treatment
If prevention fails, treatment is next. Again, in the case of heatstroke, it’s time for an ambulance.
If symptoms are “only” of heat exhaustion and are more mild, then:
- Move to a cooler location
- Rehydrate again
- Remove clothing that’s confining or too thick
- What does confining mean? Clothing that’s tight and may interfere with the body’s ability to lose heat.
- For example, you might want to lose your sports bra, but there is no need to lose a bikini, for instance.
- What does confining mean? Clothing that’s tight and may interfere with the body’s ability to lose heat.
- Use ice packs or towels soaked in cold water, applied to your body, especially wear circulation is easiest to affect, e.g. forehead, wrists, back of neck, under the arms, or groin.
- A cool bath or shower, or a dip in the pool may help cool you down, but only do this if there’s someone else around and you’re not too dizzy.
- This isn’t a good moment to go in the sea, no matter how refreshing it would be. You do not want to avoid heatstroke by drowning instead.
If full recovery doesn’t occur within a couple of hours, seek medical help.
Stay safe and have fun!

Stop Walking on Eggshells – by Randi Kreger & Paul Mason
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.
As you may gather from the title, the angle here is not “Borderline Personality Disorder is fine and dandy”, but nor is it something anyone chooses to have, and as such, importantly, this book’s advice is also not “and so you should immediately disown, divorce, defenestrate your partner”, either.
Rather, it has a balanced and compassionate approach that examines both the pitfalls and the possibilities, and provides the tools to make your relationship feel (and hopefully, actually be) safe for all concerned.
And yes, ending a relationship is always an option too, even if it can sometimes feel like it’s not, on account of how the relationships of people with BPD often have a lot of “near miss” situations, nearly ending but not quite, or (in the case of a partner who’s amenable to such), off-and-on relationships—either of which can make it seem like it’ll never truly be over.
First, though, the authors do look at a variety of ways of avoiding that outcome; making changes within oneself, setting boundaries and honing related skills, asserting your needs with confidence and clarity, and dealing with the lies, rumor-mongering, and accusations that often come with BPD. For that matter, the authors do also note that not all conflict is abuse (something that many forget), but on the flipside, how to tell when it actually is, too.
The style is very pop-science, light in tone albeit sometimes heavy in content.
Bottom line: if you or a loved one has BPD, or even just has a lot of the same symptoms as such, this book can be very helpful.
