So, no question/request too big or small
❝I’m curious about the salt part – learning about LMNT and what they say about us needing more salt than what’s recommended by the government, would you mind looking into that? From a personal experience, I definitely noticed a massive positive difference during my 3-5 day water fasts when I added salt to my water compared to when I just drank water. So I’m curious what the actual range for salt intake is that we should be aiming for.❞
That’s a fascinating question, and we’ll have to tackle it in several parts:
When fasting
3–5 days is a long time to take only water; we’re sure you know most people fast from food for much less time than that. Nevertheless, when fasting, the body needs more water than usual—because of the increase in metabolism due to freeing up bodily resources for cellular maintenance. Water is necessary when replacing cells (most of which are mostly water, by mass), and for ferrying nutrients around the body—as well as escorting unwanted substances out of the body.
Normally, the body’s natural osmoregulatory process handles this, balancing water with salts of various kinds, to maintain homeostasis.
However, it can only do that if it has the requisite parts (e.g. water and salts), and if you’re fasting from food, you’re not replenishing lost salts unless you supplement.
Normally, monitoring our salt intake can be a bit of a guessing game, but when fasting for an entire day, it’s clear how much salt we consumed in our food that day: zero
So, taking the recommended amount of sodium, which varies but is usually in the 1200–1500mg range (low end if over aged 70+; high end if aged under 50), becomes sensible.

When not fasting
Our readers here are probably not “the average person” (since we have a very health-conscious subscriber-base), but the average person in N. America consumes about 9g of salt per day, which is several multiples of the maximum recommended safe amount.
The WHO recommends no more than 5g per day, and the AHA recommends no more than 2.3g per day, and that we should aim for 1.5g per day (this is, you’ll note, consistent with the previous “1200–1500mg range”).

Questionable claims
We can’t speak for LMNT (and indeed, had to look them up to discover they are an electrolytes supplement brand), but we can say that sometimes there are articles about such things as “The doctor who says we should eat more salt, not less”, and that’s usually about Dr. James DiNicolantonio, a doctor of pharmacy, who wrote a book that, because of this question today, we’ve now also reviewed:
Spoiler, our review was not favorable.
The body knows
Our kidneys (unless they are diseased or missing) do a full-time job of getting rid of excess things from our blood, and dumping them into one’s urine.
That includes excess sugar (which is how diabetes was originally diagnosed) and excess salt. In both cases, they can only process so much, but they do their best.
Dr. DiNicolantino recognizes this in his book, but chalks it up to “if we do take too much salt, we’ll just pass it in urine, so no big deal”.
Unfortunately, this assumes that our kidneys have infinite operating capacity, and they’re good, but they’re not that good. They can only filter so much per hour (it’s about 1 liter of fluids). Remember we have about 5 liters of blood, consume 2–3 liters of water per day, and depending on our diet, several more liters of water in food (easy to consume several more liters of water in food if one eats fruit, let alone soups and stews etc), and when things arrive in our body, the body gets to work on them right away, because it doesn’t know how much time it’s going to have to get it done, before the next intake comes.
It is reasonable to believe that if we needed 8–10g of salt per day, as Dr. DiNicolantonio claims, our kidneys would not start dumping once we hit much, much lower levels in our blood (lower even than the daily recommended intake, because not all of the salt in our body is in our blood, obviously).

Lastly, a note about high blood pressure
This is one where the “salt’s not the bad guy” crowd have at least something close to a point, because while salt is indeed still a bad guy (if taken above the recommended amounts, without good medical reason), when it comes to high blood pressure specifically, it’s not the worst bad guy, nor is it even in the top 5:

When “Normal” Health Is Not What You Want

❝When going to sleep, I try to breathe through my nose (since everyone says that’s best). But when I wake I often find that I am breathing through my mouth. Is that normal, or should I have my nose checked out?❞
It is quite normal, but when it comes to health, “normal” does not always mean “optimal”.
- Good news: it is correctable!
- Bad news: it is correctable by what may be considered rather an extreme practice that comes with its own inconveniences and health risks.
Some people correct this by using medical tape to keep their mouth closed at night, ensuring nose-breathing. Advocates of this say that after using it for a while, nose-breathing in sleep will become automatic.
We know of no hard science to confirm this, and cannot even offer a personal anecdote on this one. Here are some pop-sci articles that do link to the (very few) studies that have been conducted:
- Mouth taping may be a trending sleep hack, but the science behind it is slim
- Mouth Taping for Sleep: Does it Work? And What are the Side Effects?
This writer’s personal approach is simply to do breathing exercises when going to sleep and first thing upon awakening, and settle for imperfection in this regard while asleep.
Meanwhile, take care!

15 Easy Japanese Habits That Will Transform Your 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.
The original title says “no-cost habits”, but in fairness, for most of us food is not usually free (alas). So, we will say “easy” instead, because they are indeed easy to build into your life:
15 Healthy Habits To Adopt
We’ll not keep them a mystery; they are:
- Intermittent fasting: naturally fasting for at least 12 hours overnight improves digestion and sleep quality.
- Fermented foods: regularly consuming fermented foods (like kimchi, or even just sauces like miso and shio koji) supports gut health.
- Rice & legumes over wheat: choosing wholegrain rice as a staple reduces bloating and benefits skin health (lentils are even better).
- Big breakfast, light dinner: eating a heavier breakfast and a lighter dinner gives energy in the morning and allows digestion to rest at night.
- Balancing indulgences: enjoying social meals without guilt and balancing food intake the next day.
- Daily gentle exercise: doing at least 15 minutes of yoga, Pilates, or light walking for long-term health.
- Daily baths: taking a warm bath boosts blood circulation and relaxation.
- Eating seasonal & diverse foods: including a variety of fresh, seasonal ingredients for balanced nutrition.
- Consistent morning routine: waking up at the same time, cleansing and moisturizing, and having a proper breakfast.
- Enjoying soup with meals: consuming nutrient-rich soups with vegetables and protein to prevent overeating.
- Chewing food thoroughly: eating slowly and chewing well aids digestion and enhances enjoyment.
- Light seasoning in food: avoiding overly salty or flavorful meals to appreciate natural tastes.
- Maintaining good posture: paying attention to posture during daily activities for better overall health.
- Prioritizing protein intake: eating protein-rich foods like tofu, beans, eggs, and fish, to maintain skin firmness as well as muscletone.
- Confidence in aging: focusing on internal well-being over external opinions and embracing health at every age.

Alzheimer’s may have once spread from person to person, but the risk of that happening today is incredibly low
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.
An article published this week in the prestigious journal Nature Medicine documents what is believed to be the first evidence that Alzheimer’s disease can be transmitted from person to person.
The finding arose from long-term follow up of patients who received human growth hormone (hGH) that was taken from brain tissue of deceased donors.
Preparations of donated hGH were used in medicine to treat a variety of conditions from 1959 onwards – including in Australia from the mid 60s.
The practice stopped in 1985 when it was discovered around 200 patients worldwide who had received these donations went on to develop Creuztfeldt-Jakob disease (CJD), which causes a rapidly progressive dementia. This is an otherwise extremely rare condition, affecting roughly one person in a million.
What’s CJD got to do with Alzehimer’s?
CJD is caused by prions: infective particles that are neither bacterial or viral, but consist of abnormally folded proteins that can be transmitted from cell to cell.
Other prion diseases include kuru, a dementia seen in New Guinea tribespeople caused by eating human tissue, scrapie (a disease of sheep) and variant CJD or bovine spongiform encephalopathy, otherwise known as mad cow disease. This raised public health concerns over the eating of beef products in the United Kingdom in the 1980s.
Human growth hormone used to come from donated organs
Human growth hormone (hGH) is produced in the brain by the pituitary gland. Treatments were originally prepared from purified human pituitary tissue.
But because the amount of hGH contained in a single gland is extremely small, any single dose given to any one patient could contain material from around 16,000 donated glands.
An average course of hGH treatment lasts around four years, so the chances of receiving contaminated material – even for a very rare condition such as CJD – became quite high for such people.
hGH is now manufactured synthetically in a laboratory, rather than from human tissue. So this particular mode of CJD transmission is no longer a risk.
Human growth hormone is now produced in a lab.
National Cancer Institute/UnsplashWhat are the latest findings about Alzheimer’s disease?
The Nature Medicine paper provides the first evidence that transmission of Alzheimer’s disease can occur via human-to-human transmission.
The authors examined the outcomes of people who received donated hGH until 1985. They found five such recipients had developed early-onset Alzheimer’s disease.
They considered other explanations for the findings but concluded donated hGH was the likely cause.
Given Alzheimer’s disease is a much more common illness than CJD, the authors presume those who received donated hGH before 1985 may be at higher risk of developing Alzheimer’s disease.
Alzheimer’s disease is caused by presence of two abnormally folded proteins: amyloid and tau. There is increasing evidence these proteins spread in the brain in a similar way to prion diseases. So the mode of transmission the authors propose is certainly plausible.
However, given the amyloid protein deposits in the brain at least 20 years before clinical Alzheimer’s disease develops, there is likely to be a considerable time lag before cases that might arise from the receipt of donated hGH become evident.
When was this process used in Australia?
In Australia, donated pituitary material was used from 1967 to 1985 to treat people with short stature and infertility.
More than 2,000 people received such treatment. Four developed CJD, the last case identified in 1991. All four cases were likely linked to a single contaminated batch.
The risks of any other cases of CJD developing now in pituitary material recipients, so long after the occurrence of the last identified case in Australia, are considered to be incredibly small.
Early-onset Alzheimer’s disease (defined as occurring before the age of 65) is uncommon, accounting for around 5% of all cases. Below the age of 50 it’s rare and likely to have a genetic contribution.
Early onset Alzheimer’s means it occurs before age 65.
perfectlab/ShutterstockThe risk is very low – and you can’t ‘catch’ it like a virus
The Nature Medicine paper identified five cases which were diagnosed in people aged 38 to 55. This is more than could be expected by chance, but still very low in comparison to the total number of patients treated worldwide.
Although the long “incubation period” of Alzheimer’s disease may mean more similar cases may be identified in the future, the absolute risk remains very low. The main scientific interest of the article lies in the fact it’s first to demonstrate that Alzheimer’s disease can be transmitted from person to person in a similar way to prion diseases, rather than in any public health risk.
The authors were keen to emphasise, as I will, that Alzheimer’s cannot be contracted via contact with or providing care to people with Alzheimer’s disease.

Edam vs Gouda – 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 edam to gouda, we picked the edam.
Why?
There’s not a lot between them, but there are some differences:
In terms of macros, their numbers are all close enough that one may beat the other by decimal place rounding, so we’ll call this a tie. Same goes for their fat type breakdowns; per 100g they both have 18g saturated, 8g monounsaturated, and 1g polyunsaturated.
In the category of vitamins, edam has slightly more of vitamins A, B1, B2, and B3, while gouda has slightly more of vitamins B5 and B9. A modest 4:2 win for edam.
When it comes to minerals, edam has more calcium, iron, and potassium, while gouda is not higher in any minerals. A more convincing win for edam.
In short, enjoy either or both in moderation, but if you’re going to choose one over the other, edam is the way to go.

Less Common Oral Hygiene Options
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.
Less Common Alternatives For Oral Hygiene!
You almost certainly brush your teeth. You might use mouthwash. A lot of people floss for three weeks at a time, often in January.
There are a lot of options for oral hygiene; variations of the above, and many alternatives too. This is a big topic, so rather than try to squeeze it all in one, this will be a several-part series.
- The first part was: Toothpastes & Mouthwashes: Which Help And Which Harm?
- The second part was: Flossing, Better (And Easier!)
- The third (and for now at least, final) part will look at some less common alternatives.
Tooth soap
The idea here is simplicity, and brushing with as few ingredients as possible. Soap cleans your teeth the same way it cleans your (sometimes compositionally quite similar—enamel and all) dishes, without damaging them.
We’d love to link to some science here, but alas, it appears to have not yet been done—at least, we couldn’t find any!
You can make your own tooth soap if you are feeling confident, or you might prefer to buy one ready-made (here’s an example product on Amazon, with various flavor options)
Oil pulling
We are getting gradually more scientific now; there is science for this one… But the (scientific) reviews are mixed:
Wooley et al., 2020, conducted a review of extant studies, and concluded:
❝The limited evidence suggests that oil pulling with coconut oil may have a beneficial effect on improving oral health and dental hygiene❞
The “Science-Based Medicine” project was less positive in its assessment, and declared that all and any studies that found oil pulling to be effective were a matter of researcher/publication bias. We would note that SBM is a private project and is not without its own biases, but for balance, here is what they had to offer:
A more rounded view seems to be that it is a good method for cleaning your teeth if you don’t have better options available (whereby, “better options” is “almost any other method”).
One final consideration, which the above seemed not to consider, is:
If you have sensitive teeth/gums, oil-pulling is the gentlest way of cleaning them, and getting them back into sufficient order that you can comfortably use other methods.
Want to try it? You can use any food-grade oil (coconut oil or olive oil are common choices).
Chewing stick
Not just any stick—a twig of the Salvadora persica tree. This time, there’s lots of science for it, and it’s uncontroversially effective:
❝A number of scientific studies have demonstrated that the miswak (Salvadora persica) possesses antibacterial, anti-fungal, anti-viral, anti-cariogenic, and anti-plaque properties.
Several studies have also claimed that miswak has anti-oxidant, analgesic, and anti-inflammatory effects. The use of a miswak has an immediate effect on the composition of saliva.
Several clinical studies have confirmed that the mechanical and chemical cleansing efficacy of miswak chewing sticks are equal and at times greater than that of the toothbrush❞

And about the efficacy vs using a toothbrush, here’s an example:

Scheduling Tips for Overrunning Tasks
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.
Your Questions, Our Answers!
Q: Often I schedule time for things, but the task takes longer than I think, or multiplies while I’m doing it, and then my schedule gets thrown out. Any ideas?
A: A relatable struggle! Happily, there are remedies:
- Does the task really absolutely need to be finished today? If not, just continue it in scheduled timeslots until it’s completed.
- Some tasks do indeed need to be finished today (hi, writer of a daily newsletter here!), so it can be useful to have an idea of how long things really take, in advance. While new tasks can catch us unawares, recurring or similar-to-previous tasks can be estimated based on how long they took previously. For this reason, we recommend doing a time audit every now and again, to see how you really use your time.
- A great resource that you should include in your schedule is a “spare” timeslot, ideally at least one per day. Call it a “buffer” or a “backup” or whatever (in my schedule it’s labelled “discretionary”), but the basic idea is that it’s a scheduled timeslot with nothing scheduled in it, and it works as an “overflow” catch-all.
Additionally:
- You can usually cut down the time it takes you to do tasks by setting “Deep Work” rules for yourself. For example: cut out distractions, single-task, work in for example 25-minute bursts with 5-minute breaks, etc
- You can also usually cut down the time it takes you to do tasks by making sure you’re prepared for them. Not just task-specific preparation, either! A clear head on, plenty of energy, the resources you’ll need (including refreshments!) to hand, etc can make a huge difference to efficiency.
