Keeping your kidneys happy: it’s more than just hydration!
Your kidneys are very busy organs. They filter waste products, balance hydration, pH, salt, and potassium. They also make some of our hormones, and are responsible for regulating red blood cell production too. They also handle vitamin D in a way our bodies would not work without, making them essential for calcium absorption and the health of our bones, and even muscular function.
So, how to keep them in good working order?
Yes, hydrate
This is obvious and may go without saying, but we try to not leave important things without saying. So yes, get plenty of water, spread out over the day (you can only usefully absorb so much at once!). If you feel thirsty, you’re probably already dehydrated, so have a little (hydrating!) drink.
Don’t smoke
It’s bad for everything, including your kidneys.
Look after your blood
Not just “try to keep it inside your body”, but also:
- Keep your blood sugar levels healthy (hyperglycemia can cause kidney damage)
- Keep your blood pressure healthy (hypertension can cause kidney damage)
Basically, your kidneys’ primary job of filtering blood will go much more smoothly if that blood is less problematic on the way in.
Watch your over-the-counter pill intake
A lot of PRN OTC NSAIDs (PRN = pro re nata, i.e. you take them as and when symptoms arise) (NSAIDs = Non-Steroidal Anti-Inflammatory Drugs, such as ibuprofen for example) can cause kidney damage if taken regularly.
Many people take ibuprofen (for example) constantly for chronic pain, especially the kind cause by chronic inflammation, including many autoimmune diseases.
It is recommended to not take them for more than 10 days, nor more than 8 per day. Taking more than that, or taking them for longer, could damage your kidneys temporarily or permanently.

Sesame Oil vs Almond Oil – 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 sesame oil to almond oil, we picked the almond.
Why?
We were curious about this one! Were you, or were you confident? You see, almonds tend to blow away all the other nuts with their nutritional density, but they’re far from the oiliest of nuts, and their greatest strengths include their big dose of protein and fiber (which don’t make it into the oil), vitamins (most of which don’t make it into the oil) and minerals (which don’t make it into the oil). So, a lot will come down to the fat profile!
On which note, looking at the macros first, it’s 100% fat in both cases, but sesame oil has more saturated fat and polyunsaturated fat, while almond oil has more monounsaturated fat. Since the mono- and poly-unsaturated fats are both healthy and each oil has more of one or the other, the deciding factor here is which has the least saturated fat—and that’s the almond oil, which has close to half the saturated fat of sesame oil. As an aside, neither of them are a source of omega-3 fatty acids.
In terms of vitamins, there’s not a lot to say here, but “not a lot” is not nothing: sesame oil has nearly 2x the vitamin K, while almond oil has 28x the vitamin E*, and 2x the choline. So, another win for almond oil.
*which is worth noting, not least of all because seeds are more widely associated with vitamin E in popular culture, but it’s the almond oil that provide much more here. Not to get too distracted into looking at the values of the actual seeds and nuts, almonds themselves do have over 102x the vitamin E compared to sesame seeds.
Now, back to the oils:
In the category of minerals, there actually is nothing to say here, except you can’t get more than the barest trace of any mineral from either of these two oils. So it’s a tie on this one.
Adding up the categories makes for a clear win for almond oil!

How To Rebuild Your Neurons’ Myelin Sheaths
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.
PS: We Love You
Phosphatidylserine, or “PS” for short, is a phospholipid found in the brain. In other words, a kind of fatty compound that is such stuff as our brains are made of.
In particular, it’s required for healthy nerve cell membranes and myelin (the protective sheath that neurons live in—basically, myelin sheaths do for neurons what telomere caps do for DNA).
For an overview that’s more comprehensive than we have room for here, check out:
Phosphatidylserine and the human brain
Many people take it as a supplement.
Does taking it as a supplement work?
This is a valid question, as a lot of supplements can’t be absorbed well, and/or can’t pass the blood-brain barrier. But, as the above-linked study notes:
❝Exogenous PS (300-800 mg/d) is absorbed efficiently in humans, crosses the blood-brain barrier, and safely slows, halts, or reverses biochemical alterations and structural deterioration in nerve cells. It supports human cognitive functions, including the formation of short-term memory, the consolidation of long-term memory, the ability to create new memories, the ability to retrieve memories, the ability to learn and recall information, the ability to focus attention and concentrate, the ability to reason and solve problems, language skills, and the ability to communicate. It also supports locomotor functions, especially rapid reactions and reflexes.❞
(“Exogenous” means “coming from outside of the body”, as opposed to “endogenous”, meaning “made inside the body”. Effectively, in this context “exogenous” means “taken as a supplement”.)
Why do people take it?
The health claims for phosphatidylserine fall into two main categories:
- Neuroprotection (helping your brain to avoid age-related decline in the long term)
- Cognitive enhancement (helping your brain work better in the short term)
What does the science say?
There’s a lot of science that’s been done on the neuroprotective properties of PS, and there are thousands of studies we could draw from here. The upshot is that regular phosphatidylserine supplementation (most often 300mg/day, but studies are also found for 100–500mg/day) is strongly associated with a reduction in cognitive decline over the course of 12 weeks (a common study duration). Here are a some spotlight studies showing this:
- Effects of phosphatidylserine in Alzheimer’s disease
- Double-blind cross-over study of phosphatidylserine vs. placebo in patients with early dementia of the Alzheimer type
- Effect of Phosphatidylserine on Cerebral Glucose Metabolism in Alzheimer’s Disease
- The effect of soybean-derived phosphatidylserine on cognitive performance in elderly with subjective memory complaints
Note: PS can be derived from various sources, with the two most common forms being bovine (i.e., from cow brains) or soy-derived.
There is no established difference in the efficacy of these.
There have been some concerns raised about the risk of CJD (the human form of BSE, as in “mad cow disease”) from consuming brain matter from cows, but studies have not found any evidence of this actually happening.
There is also some evidence that phosphatidyserine significantly boosts cognitive performance, even in young people with no extant cognitive decline, for example:
(as the title suggests, they did also test for its effect on mood and endocrine response, but found it made no difference to those, just the cognitive function—which enjoyed a boost before exercise, as well as after it, meaning that the boost wasn’t dependent on the exercise)
PS for cognitive enhancement in the young and healthy is not nearly so well-explored as its use as a later-life guard against age-related cognitive decline. However, just because the studies in younger people are dwarfed in number by the studies in older people, doesn’t detract from the validity of the studies in younger people.
Basically: its use in older people has been studied the most, but all available evidence points to it being beneficial to brain health at all ages.

Longans vs Lychees – 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 longans to lychees, we picked the lychees.
Why?
These two fruits are more closely related than they look from the outside, both being members of the soapberry family. However, there are some differences:
In terms of macros, longans have more protein while lychees have more carbs, and they are equal on fiber, giving longans the lower glycemic index. They’re both good, but longans nominally take the win on this one.
When it comes to vitamins, longans have more of vitamins B1, B2, and C, while lychees have more of vitamins B3, B6, B9, E, K, and choline, making for a respectable win for lychees in this category.
In the category of minerals, longans have more copper and potassium, while lychees have more calcium, iron, manganese phosphorus, and zinc. Thus, a win for lychees here too.
It’s worth looking at polyphenols too—lychees have around 10x more, which is notable.
Adding up the categories makes for an overall win for lychees, but by all means enjoy either or both! Diversity is good.

Can You Shrink A Waist In Seven Days?
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 don’t usually do this sort of video, but it seems timely before the new year. The exercises shown here are very good, and the small dietary tweak is what makes it work:
The method
Firstly, the small dietary tweak is: abstaining from foods that cause bloating, such as flour and dairy. She does say “брожение” (fermentation), but we don’t really use the word that way in English. On which note: she is Ukrainian and speaking Russian (context: many Ukrainians grew up speaking both languages), so you will need the subtitles on if you don’t understand Russian, but a) it’s worth it b) the subtitles have been put in manually so they’re a respectable translation.
Secondly, spoiler, she loses about 2 inches.
The exercises are:
- Pelvic swing-thrusts: sit, supporting yourself on your hands with your butt off the floor; raise your pelvis up to a table position, do 30 repetitions.
- Leg raises in high plank: perform 20 lifts per leg, each to its side.
- Leg raises (lying on back): do 20 repetitions.
- V-crunches: perform 30 repetitions.
- V-twists: lean on hands and do 25 repetitions.
These exercises (all five done daily for the 7 days) are great for core strength, and core muscletone is what keeps your innards in place, rather than letting them drop down (and out).
Thus, there’s only a small amount of actual fat loss going on here (if any), but it slims the waistline by improving muscletone and simultaneously decreasing bloating, which are both good changes.

Fight Inflammation & Protect Your Brain, With Quercetin
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.
Querying Quercetin
Quercetin is a flavonoid (and thus, antioxidant) pigment found in many plants. Capers, radishes, and coriander/cilantro score highly, but the list is large:
USDA Database for the Flavonoid Content of Selected Foods
Indeed,
❝Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders❞
~ Dr. Aleksandra Kozłpwsla & Dr. Dorota Szostak-Wegierek
Read more: Flavonoids—food sources and health benefits
For this reason, quercetin is often sold/consumed as a supplement on the strength of its health-giving properties.
But what does the science say?
Quercetin and inflammation
In short, it helps:
❝500 mg per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and Health Assessment Questionnaire scores in women with rheumatoid athritis❞
Quercetin and blood pressure
It works, if antihypertensive (i.e., blood pressure lowering) effect is what you want/need:
❝…significant effect of quercetin supplementation in the reduction of BP, possibly limited to, or greater with dosages of >500 mg/day.❞
~ Dr. Maria-Corina Serban et al.
Quercetin and diabetes
We’re less confident to claim this one, because (almost?) all of the research so far as been in non-human animals or in vitro. As one team of researchers put it:
❝Despite the wealth of in animal research results suggesting the anti-diabetic and its complications potential of quercetin, its efficacy in diabetic human subjects is yet to be explored❞
Quercetin and neuroprotection
Research has been done into the effect of quercetin on the risk of Parkinson’s disease and Alzheimer’s disease, and they found…
❝The data indicate that quercetin is the major neuroprotective component in coffee against Parkinson’s disease and Alzheimer’s disease❞
Read more: Quercetin, not caffeine, is a major neuroprotective component in coffee
Summary
Quercetin is a wonderful flavonoid that can be enjoyed as part of one’s diet and by supplementation. In terms of its popular health claims:
- It has been found very effective for lowering inflammation
- It has a moderate blood pressure lowering effect
- It may have anti-diabetes potential, but the science is young
- It has been found to have a potent neuroprotective effect

The Mental Health Dangers Of Oversharing
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.
Oversharers can be fun and amiable; the life of the party. In and of itself, this something that can be considered “pro-social” and thus healthy.
But the problem for one’s mental health in the long-run lies in the “over” part of oversharing. Sometimes, if not checking in with the other person’s comfort, oversharing can be “trauma-dumping”, and push people away. Alternatively, if the oversharing exposes an unmet need, it can make the other person feel obliged to try to help in some fashion, which in the long run may also cause awkwardness and withdrawal.
Some potential problems are purely internal, such the feelings of shame or anxiety that can come afterwards; “I should not have been so vulnerable”, “What if my friends think badly of me now?”, etc.
And of course, sometimes those fears are then validated by reality, if “friends” indeed take advantage of that, or withdraw their friendship. That’s a minority occurrence, but it doesn’t make it any less of a crushing thing if it happens.
Sometimes people overshare because of being a bad judge of what’s a socially-approved appropriate amount of sharing; sometimes people overshare out of a need for closeness, and perhaps the hope of hearing what one needed to hear previously.
The dangers of oversharing don’t mean that we should never speak about our experiences and feelings; in fact sometimes, it is the most healthy thing to do—be it because it’s something that needs communicating to a specific person, or because it’s something we just need to “get off our chest”.
In short, it can be good to share! It can also be good to do so judiciously, by conscious decision and not in response to a spur-of-the-moment impulse, and remember to prioritize our own safety.
Below, Alain de Botton explains more of the psychodynamics of this:

10almonds tip, not included in the video: unsure whether your urge to share is too impulsive or not? Write a letter/email, and wait until the next day to decide whether or not to send it.
