Dr. Andrea Suarez, dermatologist, shares her professional knowledge with us:
Cystn’t
First things first: lipomas and epidermoid (sebaceous*) cysts are benign, non-cancerous, and not dangerous, even though they can be annoying or uncomfortable.
*This is their most common name, but it’s misleading, as they are not sebaceous, but rather keratinous, i.e. they are not filled with sebum, but keratin.
With that in mind…
- What a lipoma is: a slow-growing, benign tumor of mature fat cells that sits below the skin, feels firm and rubbery, is usually painless, and shows no change on the skin surface. Further, they’re movable under the skin, don’t rupture or burst, can grow from about 1 to 10 cm, and don’t cause inflammation or scarring on their own.
- What an epidermoid cyst is: a cyst arising from a hair follicle or pore that contains keratin, feels fixed in the skin, and is usually same color as your skin, but with a visible punctum (small opening). It’s usually smaller than a lipoma (often 1–2 cm), may ooze foul-smelling, cheesy material when squeezed, and can resemble a large blackhead on the face.
While neither are dangerous per se, cysts to present more potential problems, especially their rupture risk—unlike lipomas, epidermoid cysts can rupture, especially if squeezed, leading to inflammation, scarring, and a higher risk of infection.
If you’re the sort of person who’s tempted to pop such things, then do be aware that popping a cyst doesn’t cure it, and in fact it encourages recurrence, makes surgical removal harder due to scar tissue, and can require antibiotics if infection develops. So please don’t do that.
So, what can be done?
Firstly, doing nothing is reasonable for both lipomas and epidermoid cysts iff they’re small and not bothersome. However, if they’re a bother, then lipomas require simple surgical excision and usually don’t come back, while epidermoid cysts also require a surgical intervention, and/but must have the entire cyst wall removed to prevent recurrence.
In few words: neither lump is life-threatening, but knowing the differences can reduce anxiety and help you decide whether observation or removal makes the most sense for you.

All About Olive Oil
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 at 10almonds!
Have a question or a request? We love to hear from you!
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 😎
❝Skip the video & tell more about olive oil please.❞
We love requests!
We can’t really do anti-requests (e.g. “skip the video”) because for every one person who doesn’t care for one particular element of the newsletter, there will be thousands who do—and indeed, the video segment is a popular one, so it will certainly remain.
However! Let us reassure you that you personally are not obliged to watch the video if you don’t want to 🙂 In fact, our general hope with 10almonds is that there will be at least one feature that is of value to each reader, each day.
Writer’s note: I’m a very bookish person, and in honesty do not love videos personally either. You know what I do love though? Olive oil. So let’s get onto that 😎
Why olive oil?
Let’s quickly address the taste/culinary side of things first, and then spend more time on the health aspects. Olive oil’s strong punchy flavor (as oils go, anyway) makes it a big winner with those of us who love strong punchy flavors. However, it does mean that it can overwhelm some more delicate dishes if one isn’t careful, meaning that it’s not perfect for everything all the time.
Healthwise, olive oil is one of the healthiest oils around, along with avocado oil. In fact, we compared them previously:
Avocado Oil vs Olive Oil – Which is Healthier?
…and it’s worth noting that their (excellent) lipids profiles are very similar, meaning that the main factor between them is that olive oil usually retains vitamins that avocado oil doesn’t.
Meanwhile, another popular contender for “healthy oil” is coconut oil, but this doesn’t have nearly as unambiguously good a lipids profile, because of coconut oil’s high saturated fat content—though lauric acid can have a cardioprotective effect, so the jury is out on that one:
Olive Oil vs Coconut Oil – Which is Healthier?
Interestingly, this article from The Conversation considered seed oils (canola, sunflower, sesame) to be next-best options:
I can’t afford olive oil. What else can I use?
…but it’s worth noting that the way those seed oils are made varies a lot from country to country, and can affect their health impact considerably.
It’s not just about the fats
Olives, especially green olives with their stronger more pungent flavor, are rich in assorted polyphenols that have many health-giving properties:
Black Olives vs Green Olives – Which is Healthier
…and olive oil is almost always made from green olives. Note that while we picked black olives in the above comparison, that’s mainly because green olives are “cured” for longer and thus are much higher in sodium… Which, guess what, isn’t in olive oil, so with olive oil we can enjoy all of the polyphenols with almost none of the sodium!
Let’s talk virginity
When it comes to olive oil, definitely not everything labelled as olive oil in the supermarket is of the same quality. Mostly, however, it’s not whether it’s “extra virgin” (i.e. the oil from the first mechanical pressing) or not that actually makes the biggest health difference, so much as that olive oils are often adulterated with other cheaper oils, so it’s important to check labels for that, even when they say “extra virgin”, in case it’s something like:
a blend of
EXTRA VIRGIN OLIVE OIL
and other oilsWe talk about this, and the various different levels of quality of olive oil and how you can tell them apart for yourself in the supermarket (and be wise to the ways they may try to trick you), here:
What to enjoy it with?
Olive oil is the single largest source of fat in the Mediterranean diet, and by that we mean not just “food that is eaten in the Mediterranean”, but rather, the well-defined dietary approach that has for a long time now been considered “the gold standard” of what a healthy diet looks like, scientifically. You can read more about what is and isn’t included in the definition, here:

Only walking for exercise? Here’s how to get the most out of it
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’re living longer than in previous generations, with one in eight elderly Australians now aged over 85. But the current gap between life expectancy (“lifespan”) and health-adjusted life expectancy (“healthspan”) is about ten years. This means many of us live with significant health problems in our later years.
To increase our healthspan, we need planned, structured and regular physical activity (or exercise). The World Health Organization recommends 150–300 minutes of moderate-intensity exercise – such as brisk walking, cycling and swimming – per week and muscle strengthening twice a week.
Yet few of us meet these recommendations. Only 10% meet the strength-training recommendations. Lack of time is one of the most common reasons.
Walking is cost-effective, doesn’t require any special equipment or training, and can be done with small pockets of time. Our preliminary research, published this week, shows there are ways to incorporate strength-training components into walking to improve your muscle strength and balance.
Why walking isn’t usually enough
Regular walking does not appear to work as muscle-strengthening exercise.
In contrast, exercises consisting of “eccentric” or muscle-lengthening contractions improve muscle strength, prevent muscle wasting and improve other functions such as balance and flexibility.
Typical eccentric contractions are seen, for example, when we sit on a chair slowly. The front thigh muscles lengthen with force generation.
When you sit down slowly on a chair, the front thigh muscles lengthen.
buritora/ShutterstockOur research
Our previous research found body-weight-based eccentric exercise training, such as sitting down on a chair slowly, improved lower limb muscle strength and balance in healthy older adults.
We also showed walking down stairs, with the front thigh muscles undergoing eccentric contractions, increased leg muscle strength and balance in older women more than walking up stairs. When climbing stairs, the front thigh muscles undergo “concentric” contractions, with the muscles shortening.
It can be difficult to find stairs or slopes suitable for eccentric exercises. But if they could be incorporated into daily walking, lower limb muscle strength and balance function could be improved.
This is where the idea of “eccentric walking” comes into play. This means inserting lunges in conventional walking, in addition to downstairs and downhill walking.
In our new research, published in the European Journal of Applied Physiology, we investigated the effects of eccentric walking on lower limb muscle strength and balance in 11 regular walkers aged 54 to 88 years.
The intervention period was 12 weeks. It consisted of four weeks of normal walking followed by eight weeks of eccentric walking.
The number of eccentric steps in the eccentric walking period gradually increased over eight weeks from 100 to 1,000 steps (including lunges, downhill and downstairs steps). Participants took a total of 3,900 eccentric steps over the eight-week eccentric walking period while the total number of steps was the same as the previous four weeks.
We measured the thickness of the participants’ front thigh muscles, muscle strength in their knee, their balance and endurance, including how many times they could go from a sitting position to standing in 30 seconds without using their arms. We took these measurements before the study started, at four weeks, after the conventional walking period, and at four and eight weeks into the eccentric walking period.
We also tested their cognitive function using a digit symbol-substitution test at the same time points of other tests. And we asked participants to complete a questionnaire relating to their activities of daily living, such as dressing and moving around at home.
Finally, we tested participants’ blood sugar, cholesterol levels and complement component 1q (C1q) concentrations, a potential marker of sarcopenia (muscle wasting with ageing).
Regular walking won’t contract your muscles in the same way as eccentric walking.
alexei_tm/ShutterstockWhat did we find?
We found no significant changes in any of the outcomes in the first four weeks when participants walked conventionally.
From week four to 12, we found significant improvements in muscle strength (19%), chair-stand ability (24%), balance (45%) and a cognitive function test (21%).
Serum C1q concentration decreased by 10% after the eccentric walking intervention, indicating participants’ muscles were effectively stimulated.
The sample size of the study was small, so we need larger and more comprehensive studies to verify our findings and investigate whether eccentric walking is effective for sedentary people, older people, how the different types of eccentric exercise compare and the potential cognitive and mental health benefits.
But, in the meantime, “eccentric walking” appears to be a beneficial exercise that will extend your healthspan. It may look a bit eccentric if we insert lunges while walking on the street, but the more people do it and benefit from it, the less eccentric it will become.

The Energy Plan – by James Collins
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.
There’s a lot of conflicting advice out there about how we should maintain our energy levels, for example:
- Eat fewer carbs!
- Eat more carbs!
- Eat slow-release carbs!
- Eat quick-release carbs!
- Practise intermittent fasting!
- Graze constantly throughout the day!
- Forget carbs and focus on fats!
- Actually it’s all about B-vitamins!
…and so on.
What Collins does differently is something much less-often seen:
Here, we’re advised on how to tailor our meals to our actual lifestyle, taking into account the day we actually have each day. For example:
- What will our energy needs be for the day?
- Will our needs be intense, or long, or both, or neither?
- What kind of recovery have we had, or do we need, from previous activities?
- Do we need to replace lost muscle glycogen, or are we looking to trim the fat?
- Are we doing a power-up or just maintenance today?
Rather than bidding us have a five-way spreadsheet and do advanced mathematics for every meal, though, Collins has done the hard work for us. The book explains the various principles in a casual format with a light conversational tone, and gives us general rules to follow.
These rules cover what to do for different times of day… and also, at different points in our life (the metabolic needs of a 13-year-old, 33-year-old, and 83-year-old, are very different!). That latter’s particularly handy, as a lot of books assume an age bracket for the reader, and this one doesn’t.
In short: a great book for anyone who wants to keep their energy levels up (throughout life’s ups and downs in activity) without piling on the pounds or starving oneself.

10 Lessons For A Healthy Mind & Body
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.
Sadia Badiei, food scientist of “Pick Up Limes” culinary fame, has advice in and out of the kitchen:
Pick up a zest for life
Here’s what she picked up, and we all can too:
- “I can’t do it… yet”: it’s never too late to adopt a growth mindset by adding “yet” to your self-doubt, focusing on progress and the possibility of improvement.
- The spotlight effect: people are generally too absorbed in their own lives to focus on you, so don’t worry too much about others’ perceptions.
- Nutrition by addition: focus on adding healthier foods to your diet rather than eliminating the less healthy ones to avoid restrictive mindsets. You can still eliminate the less healthy ones if you want to! It just shouldn’t be the primary focus. Focusing on a conceptually negative thing is rarely helpful.
- It’s ok to change: embrace change as a sign of growth and evolution, rather than seeing it as a failure or waste of time.
- The way you do one thing is the way you do everything: be mindful of how you approach small tasks, regular tasks, boring tasks, unwanted tasks—you can either create a habit of enthusiasm or a habit of suffering (it’s entirely your choice which)
- Setting goals for success: set goals based on actions you can control (inputs) rather than outcomes that are uncertain. Less “lose 10 lbs”, and more “eat fiber before starch”, for example.
- You probably can’t have it all at once: you can achieve all your dreams, but often not simultaneously; goals and desires unfold in stages over time.
- The five-year rule: before adopting a new lifestyle or habit, ask yourself if you can realistically sustain it for five years to ensure it’s not just a short-term fix. If you struggle with this prognostic, look backwards first instead. Which healthy habits have you maintained for decades, and which were you never able to make stick?
- Are you afraid or excited?: reframe fear as excitement, as both emotions share similar physical sensations and signify that you care about the outcome.
- The voice you hear most: speak kindly to yourself in self-talk to create a softer, more compassionate tone. Your subconscious is always listening, so reinforce healthy rather than unhealthy thought patterns.

Broccoli vs Green Beans – 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 broccoli to green beans, we picked the broccoli.
Why?
Both are great! But…
In terms of macros, broccoli has more protein (surprising to beat a plant that has “beans” in the name for this, but it is as it is), while the green beans have more carbs, and the two plants have equal fiber, so we call that a win for broccoli.
In the category of vitamins, broccoli has more of vitamins A, B2, B3, B5, B6, B7, B9, C, E, and K, while green beans have more vitamin B1, so that’s an overwhelming win for broccoli in this round.
Looking at minerals next, broccoli has more calcium, phosphorus, potassium, selenium, and zinc, while green beans have more iron and manganese, yielding a 5:2 win for broccoli here.
In other considerations, broccoli also has sulforaphane (see the “learn more” section below), which is another point in its favor.
Adding up the sections makes for a very clear overall win for broccoli, but by all means do enjoy either or both, as diversity is best!

Elderberries vs Raspberries – 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 elderberries to raspberries, we picked the elderberries.
Why?
It was close!
In terms of macros, elderberries have very slightly more fiber and carbs, but honestly it’s close enough to call this round a tie.
In the category of vitamins, elderberries have more of vitamins A, B1, B2, B6, and C, while raspberries have more of vitamins B3, B5, and B9. Thus, a 6:3 win for elderberries.
When it comes to minerals, elderberries have more calcium, iron, phosphorus, potassium, and selenium, while raspberries have more copper, magnesium, and zinc. This time, a 5:3 win for elderberries.
It’s also worth noting that elderberries have a far greater complement of polyphenols (mostly anthocyanins, whence the color, though also a fair amount of quercetin). We’ll mention also that raspberries certainly are good in this regard too, just not on the same tier as elderberries in this category.
Adding up the sections makes for a clear overall win for elderberries, but by all means enjoy either or both; diversity is good!
