We have written before about the health benefits (and risks) of coffee; for most people, the benefits far outweigh the risks, but individual cases may vary:
The Bitter Truth About Coffee (or is it?) ← this is a mythbusting edition
Speaking of bitterness; coffee has abundant polyphenols, which means…
- Coffee is the world’s biggest source of antioxidants
- 65% reduced risk of Alzheimer’s for coffee-drinkers
- 67% reduced risk of type 2 diabetes for coffee-drinkers
- 43% reduced risk of liver cancer for coffee-drinkers
- 53% reduced suicide risk for coffee-drinkers

There are also gut health benefits from drinking coffee, and what’s good for our gut is invariably good for our heart and brain:

The latest science on coffee and heart health
Specifically, on coffee and cholesterol levels, so for a quick primer on cholesterol, check out: Demystifying Cholesterol
High total cholesterol, and especially high LDL (“bad” cholesterol) is generally associated with cardiovascular disease, for the reasons outlined in the link above.
Recently, researchers at Uppsala University in Sweden examined the levels of cafestol and kahweol, which are both diterpenes, substances known to increase cholesterol levels, in coffee made by various methods, including those dispensed from coffee machines in workplaces.
Two samples were taken from each machine every 2–3 weeks, and the most common kinds of machines produced the highest concentrations of diterpenes. These machines are the ones that push hot water through a small amount of ground coffee, through a wide-gauge filter, dispensing coffee into a cup in about 30 seconds.
Actual espresso machines, which work on the same principle but usually with a finer filter, higher pressure, and slower dispensing of the drink, had widely varying results, quite possibly because there is (in most machines) a human element in how tightly the ground coffee is packed into the metal filter basket.
Simple filter coffee, whether made in a coffee percolator machine or made using the pour-over method, had the lowest concentrations of diterpenes.
You can read about this study here:
However!
We were curious as to how, exactly, cafestol and kahweol increase cholesterol levels.
It turns out that research in this area has been scant, because most mice aren’t affected by it in the way that most humans are, which has limited mouse model studies.
Scant does not mean non-existent, though, and the answer came by virtue of transgenic mice (specifically, apolipoprotein (apo) E*3-Leiden transgenic mice, which do have the same reaction to cafestol as humans), the paper title sums it up nicely:
You may be wondering: what does suppression of bile acid synthesis have to do with cholesterol levels?
To oversimplify it a bit: cafestol messes with cholesterol metabolism by interfering with the enzymes involved in cholesterol metabolism (specifically, regulatory enzymes found in bile acid).
As to what it actually does in that regard: it reduces LDLR (LDL receptor) mRNA levels by 37% (that figure’s an average of the specific enzymes, sterol 27-hydroxylase and oxysterol 7α-hydroxylase, which were reduced by 32% and 48%, respectively).
Why this matters in practical terms: cafestol does not add any cholesterol to our systems, it inhibits our ability to clear LDL cholesterol, thus promoting raised LDL cholesterol levels.
In other words: if you have little or no dietary cholesterol (no dietary cholesterol, for example, if you are vegan), then your body will only have the cholesterol that it made for itself because it needed it, and as such, the body won’t need to do the same kind of clean-up job that it would if you had that coffee with a double cheeseburger with extra bacon.
As such, if you have little or no dietary cholesterol, cafestol is unlikely to have anything like the same effect on cholesterol levels.
Disclaimer: this latter is technically a hypothesis, but based on sound reasoning:
It’s the same logic that says “if you do not drink alcohol, then eating a durian fruit, which inhibits aldehyde dehydrogenase, which the body uses to metabolize alcohol, will not cause alcohol-related problems for you”.

The 4 Bad Habits That Cause The Most Falls While Walking
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 risk of falling becomes greater (both in probability and in severity of consequences) as we get older. But, many people who do fall do so for the same reasons, some of which are avoidable. Dr. Doug Weiss has advice based on extensive second-hand experience:
Best foot forward!
If any of these prompt a “surely nobody does that” response, then, good for you to not have that habit, but Dr. Weiss has seen many patients who thusly erred. And if any of these do describe how you walk, then well, you’re not alone—time to fix it, though!
- Walking with Stiff Legs: walking with a hyperextended (straight) knee instead of a slight bend (5-15°) makes it harder to adjust balance, increasing the risk of falls. This can also put extra pressure on the joints, potentially leading to osteoarthritis.
- Crossing Legs While Turning: turning by crossing one leg over the other is a common cause of falls, particularly in the elderly. To avoid this, when turning step first with the foot that is on the side you are going to go. If you have the bad habit, this may feel strange at first, but you will soon adapt.
- Looking Down While Walking: focusing only on the ground directly in front of you can cause you to miss obstacles ahead, leading to falls. Instead, practice “scanning”, alternating between looking down at the ground and looking up to maintain awareness of your surroundings.
- Shuffling Instead of Tandem Walking: shuffling with feet far apart, rather than walking with one foot in front of the other, reduces balance and increases the risk of tripping. Tandem walking, where one foot is placed directly in front of the other, is the safer and more balanced way to walk.
It also helps disguise your numbers.

The Dirt Cure – by Dr. Maya Shetreat-Klein
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 we discussed in our article “Stop Sabotaging Your Gut”, there is indeed merit to living a little dirty, in particular when it comes to what we put in our mouths. Having the space of an entire book rather than a small article, Dr. Shetreat-Klein expands on this in great detail.
The subtitle mentions “growing healthy kids with food straight from the soil”; it’s worth noting that all the information here (with the exception of concerning breastfeeding etc) is equally applicable to adults too—so if it’s your own health you’re focused on rather than that of kids or grandkids, then that’s fine too.
You may be wondering: what more is there to say than “don’t scrub your vegetables as though you’re about to perform surgery with them”?
There’s a lot of background information on what things help or harm our bodies in the first place, most notably via our gut, and as an important extra consideration, the gut-brain axis. Incidentally, the author is a neurologist by professional background.
Then she gets more specific, into “include and exclude” recommendations. In this matter we have one criticism: she does recommend raw milk over pasteurized, and that is, by overwhelming scientific consensus, a terrible idea. Raw milk is an abundant source of pathogens and a breeding ground for even more. There is “living dirty” and there is “living dangerously”, and drinking raw milk is the latter. See also: Pasteurization: What It Does And Doesn’t Do
However, for the most part, the rest of her advice is sound, and there’s even a recipes section too.
The style is something of a polemic throughout, but the extensive venting does not take away from there being a lot of genuine information in here too.
Bottom line: please skip the raw milk, but aside from that, if you’d like to improve your diet to improve your gut and immune health, then this book can help with that.

Your Simplest Life – by Lisa Turner

We probably know how to declutter, and perhaps even do a “unnecessary financial expenditures” audit. So, what does this offer beyond that?
A large portion of this book focuses on keeping our general life in a state of “flow”, and strategies include:
- How to make sure you’re doing the right part of the 80:20 split on a daily basis
- Knowing when to switch tasks, and when not to
- Knowing how to plan time for tasks
- No more reckless optimism, but also without falling foul of Parkinson’s Law (i.e. work expands to fill the time allotted to it)
- Decluttering your head, too!
When it comes to managing life responsibilities in general, Turner is very attuned to generational differences… Including the different challenges faced by each generation, what’s more often expected of us, what we’re used to, and how we probably initially learned to do it (or not).
To this end, a lot of strategies are tailored with variations for each age group. Not often does an author take the time to address each part of their readership like that, and it’s really helpful that she does!
All in all, a great book for simplifying your daily life.

Hair growth strategies for men combing caffeine and minoxidil?
Well, the strategy for that is to use caffeine and minoxidil! Some more specific tips, though:
- Both of those things need to be massaged (gently!) into your scalp especially around your hairline.
- In the case of caffeine, that boosts hair growth. No extra thought or care needed for that one.
- In the case of minoxidil, it reboots the hair growth cycle, so if you’ve only recently started, don’t be surprised (or worried) if you see more shedding in the first three months. It’s jettisoning your old hairs because new ones were just prompted (by the minoxidil) to start growing behind them. So: it will get briefly worse before it gets better, but then it’ll stay better… provided you keep using it.
- If you’d like other options besides minoxidil, finasteride is a commonly prescribed oral drug that blocks the conversion of testosterone to DHT, which latter is what tells your hairline to recede.
- If you’d like other options besides prescription drugs, saw palmetto performs comparably to finasteride (and works the same way).
- You may also want to consider biotin supplementation if you don’t already enjoy that
- Consider also using a dermaroller on your scalp. If you’re unfamiliar, this is a device that looks like a tiny lawn aerator, with many tiny needles, and you roll it gently across your skin.
- It can be used for promoting hair growth, as well as for reducing wrinkles and (more slowly) healing scars.
- It works by breaking up the sebum that may be blocking new hair growth, and also makes the skin healthier by stimulating production of collagen and elastin (in response to the thousands of microscopic wounds that the needles make).
- Sounds drastic, but it doesn’t hurt and doesn’t leave any visible marks—the needles are that tiny. Still, practise good sterilization and ensure your skin is clean when using it.
See: How To Use A Dermaroller ← also explains more of the science of it
PS: this question was asked in the context of men, but the information goes the same for women suffering from androgenic alepoceia—which is a lot more common than most people think!

The Circadian Diabetes Code – by Dr. Satchin Panda
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 have previously reviewed Dr. Panda’s “The Circadian Code” which pertains to the circadian rhythms (yes, plural) in general; this one uses much of the same research, but with a strong focus on the implications for blood sugar management.
It’s first a primer in diabetes (and prediabetes, and, in contrast, what things should look like if healthy). You’ll understand about glucose metabolism and glycogen and insulin and more; you’ll understand what blood sugar readings mean, and you’ll know what an Hb1AC count actually is and what it should look like too, things like that.
After that, it’s indeed about what the subtitle promises: the right times to eat (and what to eat), when to exercise (and how, at which time), and how to optimize your sleep in the context of circadian rhythm and blood sugar management.
You may be wondering: why does circadian rhythm matter for blood sugars? And the answer is explained at some length in the first part of the book, but to oversimplify greatly: your body needs energy all the time, no matter when it was that you last ate. Thus, it has to organize its energy reserves to that at all times you can 1) function, on a cellular level 2) maintain a steady balance of sugar in your blood despite using it at slightly higher or lower levels at different times of day. Because the basal metabolic rate accounts for most of our energy use, the body has to plan for a base rate of so much energy per day, and to do that, it needs to know what a day is. Dr. Panda explains this in detail (the marvels of PER proteins and all that), but basically, that’s the relevance of circadian rhythm.
However, it’s not all theory and biochemistry; there is also a 12-week program to reverse prediabetes and type 2 diabetes (it will not, of course, reverse Type 1 Diabetes, sorry—but the program will still be beneficial even in that case, since more even blood sugars means fewer woes).
They style is friendly and clear, explaining the science simply, yet without patronizing the reader. References are given, with claims sourced in an extensive bibliography.
Bottom line: if you or a loved one have diabetes or prediabetes, or just have a strong desire to avoid getting such and generally keep your metabolic health in good order, this book will definitely help.

Which Comes First, Cardio or Weights? – by Alex Hutchinson
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 book of questions and answers, myths and busts, and in short, all things exercise.
It’s laid out as many micro-chapters with questions as headers. The explanations are clear and easy to understand, with several citations (of studies and other academic papers) per question.
While it’s quite comprehensive (weighing in at a hefty 300+ pages), it’s not the kind of book where one could just look up any given piece of information that one wants.
Its strength, rather, lies in pre-emptively arming the reader with knowledge, and correcting many commonly-believed myths. It can be read cover-to-cover, or just dipped into per what interests you (the table of contents lists all questions, so it’s easy to flip through).
Bottom line: if you’ve found the world of exercise a little confusing and would like it demystifying, this book will result in a lot of “Oooooh” moments.
Click here to check out Which Comes First, Cardio or Weights?, and know your stuff!
PS: the short answer to the titular question is “mix it up and keep it varied”
