According to social media, carbs come in various guises: naked carbs, net carbs, complex carbs and more.
You might be wondering what these terms mean or if all carbs are really the same. If you are into “carb counting” or “cutting carbs”, it’s important to make informed decisions about what you eat.
What are carbs?
Carbohydrates, or “carbs” for short, are one of the main sources of energy we need for brain function, muscle movement, digestion and pretty much everything our bodies do.
There are two classifications of carbs, simple and complex. Simple carbs have one or two sugar molecules, while complex carbs are three or more sugar molecules joined together. For example, table sugar is a simple carb, but starch in potatoes is a complex carb.
All carbs need to be broken down into individual molecules by our digestive enzymes to be absorbed. Digestion of complex carbs is a much slower process than simple carbs, leading to a more gradual blood sugar increase.
Fibre is also considered a complex carb, but it has a structure our body is not capable of digesting. This means we don’t absorb it, but it helps with the movement of our stool and prevents constipation. Our good gut bacteria also love fibre as they can digest it and use it for energy – important for a healthy gut.
What about ‘naked carbs’?
“Naked carbs” is a popular term usually used to refer to foods that are mostly simple carbs, without fibre or accompanying protein or fat. White bread, sugary drinks, jams, sweets, white rice, white flour, crackers and fruit juice are examples of these foods. Ultra-processed foods, where the grains are stripped of their outer layers (including fibre and most nutrients) leaving “refined carbs”, also fall into this category.
One of the problems with naked carbs or refined carbs is they digest and absorb quickly, causing an immediate rise in blood sugar. This is followed by a rapid spike in insulin (a hormone that signals cells to remove sugar from blood) and then a drop in blood sugar. This can lead to hunger and cravings – a vicious cycle that only gets worse with eating more of the same foods.

What about ‘net carbs’?
This is another popular term tossed around in dieting discussions. Net carbs refer to the part of the carb food that we actually absorb.
Again, fibre is not easily digestible. And some carb-rich foods contain sugar alcohols, such as sweeteners (like xylitol and sorbitol) that have limited absorption and little to no effect on blood sugar. Deducting the value of fibre and sugar alcohols from the total carbohydrate content of a food gives what’s considered its net carb value.
For example, canned pear in juice has around 12.3g of “total carbohydrates” per 100g, including 1.7g carb + 1.7g fibre + 1.9g sugar alcohol. So its net carb is 12.3g – 1.7g – 1.9g = 8.7g. This means 8.7g of the 12.3g total carbs impacts blood sugar.
The nutrition labels on packaged foods in Australia and New Zealand usually list fibre separately to carbohydrates, so the net carbs have already been calculated. This is not the case in other countries, where “total carbohydrates” are listed.
Does it matter though?
Whether or not you should care about net or naked carbs depends on your dietary preferences, health goals, food accessibility and overall nutritional needs. Generally speaking, we should try to limit our consumption of simple and refined carbs.
The latest World Health Organization guidelines recommend our carbohydrate intake should ideally come primarily from whole grains, vegetables, fruits and pulses, which are rich in complex carbs and fibre. This can have significant health benefits (to regulate hunger, improve cholesterol or help with weight management) and reduce the risk of conditions such as heart disease, obesity and colon cancer.
In moderation, naked carbs aren’t necessarily bad. But pairing them with fats, protein or fibre can slow down the digestion and absorption of sugar. This can help to stabilise blood sugar levels, prevent spikes and crashes and support personal weight management goals. If you’re managing diabetes or insulin resistance, paying attention to the composition of your meals, and the quality of your carbohydrate sources is essential.
A ketogenic (high fat, low carb) diet typically restricts carb intake to between 20 and 50g each day. But this carb amount refers to net carbs – so it is possible to eat more carbs from high-fibre sources.

Some tips to try
Some simple strategies can help you get the most out of your carb intake:
reduce your intake of naked carbs and foods high in sugar and white flour, such as white bread, table sugar, honey, lollies, maple syrup, jam, and fruit juice
opt for protein- and fibre-rich carbs. These include oats, sweet potatoes, nuts, avocados, beans, whole grains and broccoli
if you are eating naked carbs, dress them up with some protein, fat and fibre. For example, top white bread with a nut butter rather than jam
if you are trying to reduce the carb content in your diet, be wary of any symptoms of low blood glucose, including headaches, nausea, and dizziness
- working with a health-care professional such as an accredited practising dietitian or your GP can help develop an individualised diet plan that meets your specific needs and goals.

The Seven Circles – by Chelsey Luger & Thosh 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.
At first glance, this can seem like an unscientific book—you won’t find links to studies in this one, for sure! However, if we take a look at the seven circles in question, they are:
- Food
- Movement
- Sleep
- Ceremony
- Sacred Space
- Land
- Community
Regular 10almonds readers may notice that these seven items contain five of the things strongly associated with the “supercentenarian Blue Zones”. (If you are wondering why Native American reservations are not Blue Zones, the answer there lies less in health science and more in history and sociology, and what things have been done to a given people).
The authors—who are Native American, yes—present in one place a wealth of knowledge and know-how. Not even just from their own knowledge and their own respective tribes, but gathered from other tribes too.
Perhaps the strongest value of this book to the reader is in the explanation of noting the size of each of those circles, how they connect with each other, and providing a whole well-explained system for how we can grow each of them in harmony with each other.
Or to say the same thing in sciencey terms: how to mindfully improve integrated lifestyle factors synergistically for greater efficacy and improved health-adjusted quality-of-life years.
Bottom line: if you’re not averse to something that mostly doesn’t use sciencey terms of have citations to peer-reviewed studies peppered through the text, then this book has wisdom that’s a) older than the pyramids of Giza, yet also b) highly consistent with our current best science of Blue Zone healthy longevity.

What You Should Have Been Told About The Menopause Beforehand
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.
What You Should Have Been Told About Menopause Beforehand
This is Dr. Jen Gunter. She’s a gynecologist, specializing in chronic pain and vulvovaginal disorders. She’s also a woman on a mission to demystify things that popular culture, especially in the US, would rather not talk about.
When was the last time you remember the menopause being referenced in a movie or TV show? If you can think of one at all, was it just played for laughs?
And of course, the human body can be funny, so that’s not necessarily the problem, but it sure would be nice if that weren’t all that there is!
So, what does Dr. Gunter want us to know?
It’s a time of changes, not an end
The name “menopause” is misleading. It’s not a “pause”, and those menses aren’t coming back.
And yet, to call it a “menostop” would be differently misleading, because there’s a lot more going on than a simple cessation of menstruation.
Estrogen levels will drop a lot, testosterone levels may rise slightly, mood and sleep and appetite and sex drive will probably be affected (progesterone can improve all these things!) and
not to mention butwe’re going to mention: vaginal atrophy, which is very normal and very treatable with a topical estrogen cream. Untreated menopause can also bring a whole lot of increased health risks (for example, heart disease, osteoporosis, and, counterintuitively given the lower estrogen levels, breast cancer).However, with a little awareness and appropriate management, all these things can usually be navigated with minimal adverse health outcomes.
Dr Gunter, for this reason, refers to it interchangeably as “the menopausal transition”. She describes it as being less like a cliff edge we fall off, and more like a bridge we cross.
Bridges can be dangerous to cross! But they can also get us safely where we’re going.
Ok, so how do we manage those things?
Dr. Gunter is a big fan of evidence-based medicine, so we’ll not be seeing any yonic crystals or jade eggs. Or “goop”.
See also: Meet Goop’s Number One Enemy
For most people, she recommends Menopausal Hormone Therapy (MHT), which falls under the more general category of Hormone Replacement Therapy (HRT).
This is the most well-evidenced, science-based way to avoid most of the risks associated with menopause.
Nevertheless, there are scare-stories out there, ranging from painful recommencement of bleeding, to (once again) increased risk of breast cancer. However, most of these are either misunderstandings, or unrelated to menopause and MHT, and are rather signs of other problems that should not be ignored.
To get a good grounding in this, you might want to read her Hormone Therapy Guide, freely available as a standalone section on her website. This series of posts is dedicated to hormone therapy. It starts with some basics and builds on that knowledge with each post:
Dr. Gunter’s Guide To The Hormone Menoverse
What about natural therapies?
There are some non-hormonal things that work, but these are mostly things that:
- give a statistically significant reduction in symptoms
- give the same statistically significant reduction in symptoms as placebo
As Dr. Gunter puts it:
❝While most of the studies of prescription medications for hot flashes have an appropriate placebo arm, this is rarely the case with so-called alternative therapies.
In fact, the studies here are almost always low quality, so it’s often not possible to conclude much.
Many reviews that look at these studies often end with a line that goes something like, “Randomized trials with a placebo arm, a low risk of bias, and adequate sample sizes are urgently needed.”
You should interpret this kind of conclusion as the polite way of saying, “We need studies that aren’t BS to say something constructive.”❞
However, if it works, it works, whatever its mechanism. It’s just good, when making medical decisions, to do so with the full facts!
For that matter, even Dr. Gunter acknowledges that while MHT can be lifechanging (in a positive way) for many, it’s not for everyone:
Informed Decisions: When Menopause Hormone Therapy Isn’t Recommended
Want to know more?
Dr. Gunter also has an assortment of books available, including The Menopause Manifesto (which we’ve reviewed previously), and some others that we haven’t, such as “Blood” and “The Vagina Bible”.

Prevention Is Better Than Cure

Preventative healthcare is the theme this week:
New year, new risks
The start of a new year is a great time to update adult vaccinations, including the flu shot, any COVID-19 boosters, and vaccines for pneumonia, shingles, and tetanus—when was your last booster, after all? Vaccination recommendations vary by age and health conditions, so do check what’s appropriate in your case. Key vaccines include the pneumonia vaccine for those 65 and older, the shingles vaccine for adults over 50, and the Tdap vaccine every 10 years to protect against tetanus, diphtheria, and pertussis (whooping cough), especially for new parents and grandparents, to protect infants:

The heart-healthiest swap you can do
Based on a large (n=202,863, of which 160,123 women and 42,740 men) dataset, a higher plant-to-animal protein ratio is associated with significantly lower risks of cardiovascular disease (CVD) and coronary artery disease (CAD), with diets lower in meat (especially if lower in red meat) and instead rich in plant-based proteins like legumes, nuts, and whole grains reducing CVD risk by 19% and coronary artery disease risk by 27%. Which is quite considerable.
Substituting even small amounts of animal protein (especially if it’s red meat) with plant protein further enhances heart health:

Let’s keep pan-resistant superbugs at bay
Researchers want to warn us about the threat of pan-resistant bacteria, which could render all known antibiotics ineffective, leading to a sharp rise in global infection-related deaths.
To be clear, we don’t have anything pan-resistant yet, but antibiotic-resistant superbugs are getting close, and in the long term, are likely to win the evolutionary arms race if we don’t change things to diverge considerably from our current path. Modeling a hypothetical pan-resistant E. coli strain, researchers predicted U.S. sepsis deaths could increase 18- to 46-fold within five years of its emergence.
The study calls for urgent action, including stricter antibiotic stewardship, new drug development, and monitoring technologies, emphasizing that without intervention, the global impact could be catastrophic:

How does cancer spread to other parts of the 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.
All cancers begin in a single organ or tissue, such as the lungs or skin. When these cancers are confined in their original organ or tissue, they are generally more treatable.
But a cancer that spreads is much more dangerous, as the organs it spreads to may be vital organs. A skin cancer, for example, might spread to the brain.
This new growth makes the cancer much more challenging to treat, as it can be difficult to find all the new tumours. If a cancer can invade different organs or tissues, it can quickly become lethal.
When cancer spreads in this way, it’s called metastasis. Metastasis is responsible for the majority (67%) of cancer deaths.
Cells are supposed to stick to surrounding tissue
Our bodies are made up of trillions of tiny cells. To keep us healthy, our bodies are constantly replacing old or damaged cells.
Each cell has a specific job and a set of instructions (DNA) that tells it what to do. However, sometimes DNA can get damaged.
This damage might change the instructions. A cell might now multiply uncontrollably, or lose a property known as adherence. This refers to how sticky a cell is, and how well it can cling to other surrounding cells and stay where it’s supposed to be.
If a cancer cell loses its adherence, it can break off from the original tumour and travel through the bloodstream or lymphatic system to almost anywhere. This is how metastasis happens.
Many of these travelling cancer cells will die, but some will settle in a new location and begin to form new cancers.
Some cells settle in a new location.
Scipro/ShutterstockParticular cancers are more likely to metastasise to particular organs that help support their growth. Breast cancers commonly metastasise to the bones, liver, and lungs, while skin cancers like melanomas are more likely to end up in the brain and heart.
Unlike cancers which form in solid organs or tissues, blood cancers like leukaemia already move freely through the bloodstream, but can escape to settle in other organs like the liver or brain.
When do cancers metastasise?
The longer a cancer grows, the more likely it is to metastasise. If not caught early, a patient’s cancer may have metastasised even before it’s initially diagnosed.
Metastasis can also occur after cancer treatment. This happens when cancer cells are dormant during treatment – drugs may not “see” those cells. These invisible cells can remain hidden in the body, only to wake up and begin growing into a new cancer months or even years later.
For patients who already have cancer metastases at diagnosis, identifying the location of the original tumour – called the “primary site” – is important. A cancer that began in the breast but has spread to the liver will probably still behave like a breast cancer, and so will respond best to an anti-breast cancer therapy, and not anti-liver cancer therapy.
As metastases can sometimes grow faster than the original tumour, it’s not always easy to tell which tumour came first. These cancers are called “cancers of unknown primary” and are the 11th most commonly diagnosed cancers in Australia.
One way to improve the treatment of metastatic cancer is to improve our ways of detecting and identifying cancers, to ensure patients receive the most effective drugs for their cancer type.
What increases the chances of metastasis and how can it be prevented?
If left untreated, most cancers will eventually acquire the ability to metastasise.
While there are currently no interventions that specifically prevent metastasis, cancer patients who have their tumours surgically removed may also be given chemotherapy (or other drugs) to try and weed out any hidden cancer cells still floating around.
The best way to prevent metastasis is to diagnose and treat cancers early. Cancer screening initiatives such as Australia’s cervical, bowel, and breast cancer screening programs are excellent ways to detect cancers early and reduce the chances of metastasis.
The best way to prevent cancer spreading is to diagnose and treat them early.
Peakstock/ShutterstockNew screening programs to detect cancers early are being researched for many types of cancer. Some of these are simple: CT scans of the body to look for any potential tumours, such as in England’s new lung cancer screening program.
Using artificial intelligence (AI) to help examine patient scans is also possible, which might identify new patterns that suggest a cancer is present, and improve cancer detection from these programs.
More advanced screening methods are also in development. The United States government’s Cancer Moonshot program is currently funding research into blood tests that could detect many types of cancer at early stages.
One day there might even be a RAT-type test for cancer, like there is for COVID.
Will we be able to prevent metastasis in the future?
Understanding how metastasis occurs allows us to figure out new ways to prevent it. One idea is to target dormant cancer cells and prevent them from waking up.
Directly preventing metastasis with drugs is not yet possible. But there is hope that as research efforts continue to improve cancer therapies, they will also be more effective at treating metastatic cancers.
For now, early detection is the best way to ensure a patient can beat their cancer.

Coffee, From A Blood Sugar Management Perspective
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 favorite French biochemist (Jessie Inchauspé) is back, and this time, she’s tackling a topic near and dear to this writer’s heart: coffee ☕💕
What to consider
Depending on how you like your coffee, some or all of these may apply to you:
- Is coffee healthy? Coffee is generally healthy, reducing the risk of type 2 diabetes by improving fat burning in the liver and protecting beta cells in the pancreas.
- Does it spike blood sugars? Usually not so long as it’s black and unsweetened. Black coffee can cause small glucose spikes in some people due to stress-induced glucose release, but only if it contains caffeine.
- When is it best to drink it? Drinking coffee after breakfast, especially after a poor night’s sleep, can actually reduce glucose and insulin spikes.
- What about milk? All milks cause some glucose and insulin spikes. While oat milk is generally healthy, for blood sugar purposes unsweetened nut milks or even whole cow’s milk (but not skimmed; it needs the fat) are better options as they cause smaller spikes.
- What about sweetening? Adding sugar to coffee, especially on an empty stomach, obviously leads to large glucose spikes. Alternative sweeteners like stevia or sweet cinnamon are fine substitutes.
For more details on all of those things, plus why Kenyan coffee specifically may be the best for blood sugars, enjoy:

Move – by Caroline Williams
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.
- Get 150 minutes of moderate exercise per week, says the American Heart Association
- There are over 10,000 minutes per week, says the pocket calculator
Is 150/10,000 really the goal here? Really?
For Caroline Williams, the answer is no.
In this book that’s practically a manifesto, she outlines the case that:
- Humans evolved to move
- Industrialization and capitalism scuppered that
- We now spend far too long each day without movement
Furthermore, for Williams this isn’t just an anthropological observation, it’s a problem to be solved, because:
- Our lack of movement is crippling us—literally
- Our stagnation affects not just our bodies, but also our minds
- (again literally—there’s a direct correlation with mental health)
- We urgently need to fix this
So, what now, do we need to move in to the gym and become full-time athletes to clock up enough hours of movement? No.
Williams convincingly argues the case (using data from supercentenarian “blue zones” around the world) that even non-exertive movement is sufficient. In other words, you don’t have to be running; walking is great. You don’t have to be lifting weights; doing the housework or gardening will suffice.
From that foundational axiom, she calls on us to find ways to build our life around movement… rather than production-efficiency and/or convenience. She gives plenty of tips for such too!
Bottom line: some books are “I couldn’t put it down!” books. This one’s more of a “I got the urge to get up and get moving!” book.
