The core idea of this book is that foods can be assigned a numerical value according to their total nutritional value, and that this number can be used to guide a person’s diet such that we will eat, in aggregate, a diet that is more nutritious. So far, so simple.
What Dr. Ballantyne also does, besides explaining and illustrating this system (there are chapters explaining the calculation system, and appendices with values), is also going over what to consider important and what we can let slide, and what things we might need more of to address a wide assortment of potential health concerns. And yes, this is definitely a “positive diet” approach, i.e. it focuses on what to add in, not what to cut out.
The premise of the “positive diet” approach is simple, by the way: if we get a full set of good nutrients, we will be satisfied and not crave unhealthy food.
She also offers a lot of helpful “rules of thumb”, and provides a variety of cheat-sheets and suchlike to make things as easy as possible.
There’s also a recipes section! Though, it’s not huge and it’s probably not necessary, but it’s just one more “she’s thinking of everything” element.
Bottom line: if you’d like a single-volume “Bible of” nutrition-made-easy, this is a very usable tome.

How much time should you spend sitting versus standing? New research reveals the perfect mix for optimal 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.
People have a pretty intuitive sense of what is healthy – standing is better than sitting, exercise is great for overall health and getting good sleep is imperative.
However, if exercise in the evening may disrupt our sleep, or make us feel the need to be more sedentary to recover, a key question emerges – what is the best way to balance our 24 hours to optimise our health?
Our research attempted to answer this for risk factors for heart disease, stroke and diabetes. We found the optimal amount of sleep was 8.3 hours, while for light activity and moderate to vigorous activity, it was best to get 2.2 hours each.
Finding the right balance
Current health guidelines recommend you stick to a sensible regime of moderate-to vigorous-intensity physical activity 2.5–5 hours per week.
However mounting evidence now suggests how you spend your day can have meaningful ramifications for your health. In addition to moderate-to vigorous-intensity physical activity, this means the time you spend sitting, standing, doing light physical activity (such as walking around your house or office) and sleeping.
Our research looked at more than 2,000 adults who wore body sensors that could interpret their physical behaviours, for seven days. This gave us a sense of how they spent their average 24 hours.
At the start of the study participants had their waist circumference, blood sugar and insulin sensitivity measured. The body sensor and assessment data was matched and analysed then tested against health risk markers — such as a heart disease and stroke risk score — to create a model.
Using this model, we fed through thousands of permutations of 24 hours and found the ones with the estimated lowest associations with heart disease risk and blood-glucose levels. This created many optimal mixes of sitting, standing, light and moderate intensity activity.
When we looked at waist circumference, blood sugar, insulin sensitivity and a heart disease and stroke risk score, we noted differing optimal time zones. Where those zones mutually overlapped was ascribed the optimal zone for heart disease and diabetes risk.
You’re doing more physical activity than you think
We found light-intensity physical activity (defined as walking less than 100 steps per minute) – such as walking to the water cooler, the bathroom, or strolling casually with friends – had strong associations with glucose control, and especially in people with type 2 diabetes. This light-intensity physical activity is likely accumulated intermittently throughout the day rather than being a purposeful bout of light exercise.
Our experimental evidence shows that interrupting our sitting regularly with light-physical activity (such as taking a 3–5 minute walk every hour) can improve our metabolism, especially so after lunch.
While the moderate-to-vigorous physical activity time might seem a quite high, at more than 2 hours a day, we defined it as more than 100 steps per minute. This equates to a brisk walk.
It should be noted that these findings are preliminary. This is the first study of heart disease and diabetes risk and the “optimal” 24 hours, and the results will need further confirmation with longer prospective studies.
The data is also cross-sectional. This means that the estimates of time use are correlated with the disease risk factors, meaning it’s unclear whether how participants spent their time influences their risk factors or whether those risk factors influence how someone spends their time.
Australia’s adult physical activity guidelines need updating
Australia’s physical activity guidelines currently only recommend exercise intensity and time. A new set of guidelines are being developed to incorporate 24-hour movement. Soon Australians will be able to use these guidelines to examine their 24 hours and understand where they can make improvements.
While our new research can inform the upcoming guidelines, we should keep in mind that the recommendations are like a north star: something to head towards to improve your health. In principle this means reducing sitting time where possible, increasing standing and light-intensity physical activity, increasing more vigorous intensity physical activity, and aiming for a healthy sleep of 7.5–9 hours per night.
Beneficial changes could come in the form of reducing screen time in the evening or opting for an active commute over driving commute, or prioritising an earlier bed time over watching television in the evening.
It’s also important to acknowledge these are recommendations for an able adult. We all have different considerations, and above all, movement should be fun.

How extreme heat can affect you—and how you can protect yourself
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.
Because of climate change, last summer was the hottest in the Northern Hemisphere in 2,000 years—and this summer is expected to be even hotter. The record may continue to be broken: Extreme heat is expected to become even more frequent.
The scorching heat has led to an increase in heat-related deaths in the United States, according to the Department of Health and Human Services, with approximately 2,300 deaths in the summer of 2023. Extreme heat, defined as a period of two to three days with high heat and humidity with temperatures above 90 degrees Fahrenheit, can have serious health consequences, including symptoms like headache, dizziness, loss of consciousness, nausea, and confusion.
As we face more extreme heat, you may be wondering how you can protect yourself and your loved ones. Read on to learn about heat-related illness, who’s most at risk, and more.
What happens when our bodies are exposed to extreme heat?
As our body temperature rises, our bodies attempt to cool down by opening up more blood vessels near the skin to begin sweating. The evaporation of our sweat regulates our body temperature, but it also leads to losing fluids and minerals.
When it’s too humid, sweating alone doesn’t do the trick. The heart must work harder to bring blood around the body. It starts beating faster, which can cause light-headedness, nausea, and headache.
This process can affect our health in different ways, including increasing our risk of hospitalization for heart disease, worsening asthma, and injuring kidneys due to dehydration. It can also result in heat-related illness. Below are some effects of heat on our bodies:
- Heat cramps: Occur when a person loses salt through sweating, which causes painful cramps. Symptoms begin as painful spasms after heavy sweating, usually in the legs or the stomach. Heat cramps can lead to heat exhaustion or heat stroke.
- Heat exhaustion: This occurs when the body loses an excessive amount of water and salt, usually during intense physical activity. Symptoms include irritability, heavy sweating, and weakness, including muscle cramps. Heat exhaustion can lead to heat stroke.
- Heat stroke: This is the most severe heat-related illness. It happens when the body can’t cool down and reaches a temperature of 106 Fahrenheit or higher within 10 to 15 minutes. If the person doesn’t receive emergency treatment, it can cause permanent disability or death. Symptoms include confusion, loss of consciousness, and seizures.
What should I do if someone experiences a heat-related illness?
If you or someone you’re with begins to show signs of heat illness, the Centers for Disease Control and Prevention recommends the following:
- Heat cramps: Stop all physical activity, drink water or a sports drink, move to a cool place, and wait for cramps to go away before resuming activity. If the cramps last more than an hour, you’re on a low-sodium diet, or you have heart problems, get medical help.
- Heat exhaustion: Move the person to a cool place, loosen their clothes, use a cool bath or cloths to try to lower their body temperature, and give them a sip of water. If the person throws up, or if their symptoms last longer than an hour or worsen, get medical help.
- Heat stroke: Call 911 immediately. Then, move the person to a cooler place, use cool cloths or a cool bath to help lower their temperature, and don’t give them anything to drink.
Read more about heat-related illness and what to do in each case.
Who’s more vulnerable to extreme heat?
While everyone can be affected by extreme heat, some people are more at risk, including people of color.
A 2023 KFF report outlined that because of historical residential segregation in the U.S. (known as “redlining”), people of color are more likely to live in areas that experience higher temperatures from rooftops, asphalt, and sidewalks that retain the sun’s heat (known as the “urban heat island effect”). Additionally, communities of color are more likely to live in areas with fewer trees, which act as a canopy and provide shade, making the heat worse and more direct.
Children under 5, adults 65 or over, and pregnant people are also more vulnerable to extreme heat. If you have a chronic health condition like diabetes, heart problems, or a mental health condition, you’re also at higher risk. (Some psychiatric medications, like antidepressants, can also make people more susceptible to heat).
Lastly, anyone exposed to the sun and extreme heat for long periods is also at higher risk. This includes athletes, people who work outdoors, and unhoused people.
What can I do to prevent heat-related illness during a heat wave?
During a heat wave, follow these tips to stay cool and protect yourself from heat-related illness:
- Never leave your pets or children inside a car.
- Wear loose, light-colored clothing (dark colors absorb more heat).
- Find shade if you’re outside.
- If you don’t have air conditioning in your home, go to a place where you can cool down, such as a local library, community center, local pool or splash pad, or mall. Check to see if your city has designated cooling centers. (Cities like New York have a list of places.)
- Wear a hat.
- Drink (non-alcoholic) fluids often to stay hydrated—and if you have pets, give them water frequently as well.
- Check on your family members or older neighbors who may be more sensitive to extreme heat.
- Avoid using your stove or oven too often or during the hottest parts of the day.
- Cover your windows with shades to keep the heat out.
What are some resources to prevent heat-related illness?
If you need financial assistance to cool down your home, such as to purchase an air conditioner, apply to the federal government’s Low Income Home Energy Assistance Program.
Before you head outside during a heat wave, use the CDC’s HeatRisk tool: Enter your zip code to find the current heat risk in your area and get tips on what to do to stay safe with each risk level.
During a heat wave, also look for a cooling center in your state using the National Center for Healthy Housing’s list.
Check out the National Weather Service’s for more tips and resources.

28-Day FAST Start Day-by-Day – by Gin Stephens
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 Gin Stephens’ other book, “Fast. Feast. Repeat.”, so what’s so special about this one that it deserves reviewing too?
This one is all about troubleshooting the pitfalls that many people find when taking up intermittent fasting.
To be clear: the goal here is not a “28 days and yay you did it, put that behind you now”, but rather “28 days and you are now intermittently fasting easily each day and can keep it up without difficulty”. As for the difficulties that may arise early in the 28 days…
Not just issues of willpower, but also the accidental breaks. For example, some artificial sweeteners, while zero-calorie, trigger an insulin response, which breaks the fast on the metabolic level (avoiding that is the whole point of IF). Lots of little tips like that peppered through the book help the reader to stop accidentally self-sabotaging their progress.
The author does talk about psychological issues too, and also how it will feel different at first while the liver is adapting, than later when it has already depleted its glycogen reserves and the body must burn body fat instead. Information like that makes it easier to understand that some initial problems (hunger, getting “hangry”, feeling twitchy, or feeling light-headed) will last only a few weeks and then disappear.
So, understanding things like that makes a big difference too.
The style of the book is simple and clear pop-science, with lots of charts and bullet points and callout-boxes and the like; it makes for very easy reading, and very quick learning of all the salient points, of which there are many.
Bottom line: if you’ve tried intermittent fasting but struggled to make it stick, this book can help you get to where you want to be.

The Life-Changing Manga Of Tidying Up – by Marie Kondo
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.
Everyone knows the slogan “does this spark joy?”, but there’s a whole method to the magic that goes far beyond that. It spans all manner of things from the over-arching strategy of taking on a house-sized tidying project, to practical little tips like “store these things this way instead; now they’re safe, tidy and accessible—and look good too!”.
You may be wondering: why are we reviewing this book instead of the much more famous “The Life-Changing Magic of Tidying Up”?
It’s simple: here at 10almonds, we like things to be super simple and easy to digest.
This book is smaller, simpler, and more digestible than her more famous book, without sacrificing content. And you know what? We held it in our hands and it sparked joy
Bottom line is: it’s useful, it’s beautiful, it will change your life (and your underwear drawer).
PS: this 10almonds team-member gifted a copy to her 12-year-old son. He implemented it the same day, unbidden. Magic indeed!

Yes, you still need to use sunscreen, despite what you’ve heard on TikTok
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.
Summer is nearly here. But rather than getting out the sunscreen, some TikTokers are urging followers to chuck it out and go sunscreen-free.
They claim it’s healthier to forgo sunscreen to get the full benefits of sunshine.
Here’s the science really says.
Karolina Grabowska/Pexels How does sunscreen work?
Because of Australia’s extreme UV environment, most people with pale to olive skin or other risk factors for skin cancer need to protect themselves. Applying sunscreen is a key method of protecting areas not easily covered by clothes.
Sunscreen works by absorbing or scattering UV rays before they can enter your skin and damage DNA or supportive structures such as collagen.
When UV particles hit DNA, the excess energy can damage our DNA. This damage can be repaired, but if the cell divides before the mistake is fixed, it causes a mutation that can lead to skin cancers.
The energy from a particle of UV (a photon) causes DNA strands to break apart and reconnect incorrectly. This causes a bump in the DNA strand that makes it difficult to copy accurately and can introduce mutations. NASA/David Herring The most common skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common, but is the most likely to spread around the body; this process is called metastasis.
Two in three Australians will have at least one skin cancer in their lifetime, and they make up 80% of all cancers in Australia.
Around 99% of skin cancers in Australia are caused by excessive exposure to UV radiation.
Excessive exposure to UV radiation also affects the appearance of your skin. UVA rays are able to penetrate deep into the skin, where they break down supportive structures such as elastin and collagen.
This causes signs of premature ageing, such as deep wrinkling, brown or white blotches, and broken capillaries.
Sunscreen can help prevent skin cancers
Used consistently, sunscreen reduces your risk of skin cancer and slows skin ageing.
In a Queensland study, participants either used sunscreen daily for almost five years, or continued their usual use.
At the end of five years, the daily-use group had reduced their risk of squamous cell carcinoma by 40% compared to the other group.
Ten years later, the daily use group had reduced their risk of invasive melanoma by 73%
Does sunscreen block the health-promoting properties of sunlight?
The answer is a bit more complicated, and involves personalised risk versus benefit trade-offs.
First, the good news: there are many health benefits of spending time in the sun that don’t rely on exposure to UV radiation and aren’t affected by sunscreen use.
Sunscreen only filters UV rays, not all light. Ron Lach/Pexels Sunscreen only filters UV rays, not visible light or infrared light (which we feel as heat). And importantly, some of the benefits of sunlight are obtained via the eyes.
Visible light improves mood and regulates circadian rhythm (which influences your sleep-wake cycle), and probably reduces myopia (short-sightedness) in children.
Infrared light is being investigated as a treatment for several skin, neurological, psychiatric and autoimmune disorders.
So what is the benefit of exposing skin to UV radiation?
Exposing the skin to the sun produces vitamin D, which is critical for healthy bones and muscles.
Vitamin D deficiency is surprisingly common among Australians, peaking in Victoria at 49% in winter and being lowest in Queensland at 6% in summer.
Luckily, people who are careful about sun protection can avoid vitamin D deficiency by taking a supplement.
Exposing the skin to UV radiation might have benefits independent of vitamin D production, but these are not proven. It might reduce the risk of autoimmune diseases such as multiple sclerosis or cause release of a chemical that could reduce blood pressure. However, there is not enough detail about these benefits to know whether sunscreen would be a problem.
What does this mean for you?
There are some benefits of exposing the skin to UV radiation that might be blunted by sunscreen. Whether it’s worth foregoing those benefits to avoid skin cancer depends on how susceptible you are to skin cancer.
If you have pale skin or other factors that increase you risk of skin cancer, you should aim to apply sunscreen daily on all days when the UV index is forecast to reach 3.
If you have darker skin that rarely or never burns, you can go without daily sunscreen – although you will still need protection during extended times outdoors.
For now, the balance of evidence suggests it’s better for people who are susceptible to skin cancer to continue with sun protection practices, with vitamin D supplementation if needed.

The Big Book of Kombucha – by Hannah Crum & Alex LaGory
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.
If you’ve been thinking “I should get into kombucha”, then this is the universe prompting you, because with in this book’s 400 pages is all the information you need and more.
Because, it’s understandable to be wary when starting out, from “what if my jar explodes” to “what if I poison my family”, but the authors (and photographer) take every care to ensure that everything goes perfectly, guiding us through everything from start to finish, including very many high-quality color photos of what things should (and shouldn’t) look like.
On which note, that does mean that to enjoy the color you should get a physical copy or Kindle Fire, not a Kindle e-ink version (as then it’d be black and white).
There’s also a comprehensive section on troubleshooting, as well as hundreds of recipes for all kinds of flavors and occasions.
Bottom line: in the category of books that could reasonably be called “The Bible of…”, this one’s the “The Bible of Kombucha”.
