While these are quite high-calorie, they’re also high in protein, and the fiber and healthy fats flatten the blood sugar curve:
You will need
- 1 cup peanut butter
- 4 oz dark chocolate, melted (try to get dark chocolate with >80% cocoa, if you can; 85% is very respectable and 90% is perfect)
- ⅓ cup maple syrup (you can safely reduce this, or even omit it, if you prefer less sweetness)
- ¼ cup hazelnuts
- ¼ cup almond milk (or your preferred milk, but we recommend almond for taste and health)
- 1 tsp vanilla extract
- Topping: ¼ cup hazelnuts, roughly chopped
Method
(we suggest you read everything at least once before doing anything)
1) Combine all the ingredients (except the topping) in a food processor, and blend until smooth.
2) Line a container (5″x7″ is a good size) with baking paper and spread the mixture evenly into it, pressing down gently.
3) Sprinkle the topping onto it, press that even more gently into it.
4) Refrigerate overnight (or chill it for 2hrs in the freezer).
5) Cut into cubes to serve; they can be served frozen or thawed, per your preference:

Make Your Coffee Heart-Healthier!

Health-Hack Your Coffee
We have previously written about the general health considerations (benefits and potential problems) of coffee:
The Bitter Truth About Coffee (or is it?)
Today, we will broadly assume that you are drinking coffee (in general, not necessarily right now, though if you are, same!) and would like to continue to do so. We also assume you’d like to do so as healthily as possible.
Not all coffees are created equal
If you order a coffee in France or Italy without specifying what kind, the coffee you receive will be short, dark,
and handsomeand without sugar. Healthwise, this is not a bad starting point. However…- It will usually be espresso
- Or it may be what in N. America is called a French press (in Europe it’s just called a cafetière)
Both of these kinds of coffee mean that cafestol, a compound found in the oily part of coffee and which is known to raise LDL (“bad” cholesterol”), stays in the drink.
Read: Cafestol and Kahweol: A Review on Their Bioactivities and Pharmacological Properties
Also: Cafestol extraction yield from different coffee brew mechanisms
If you’re reading that second one and wondering what a mocha pot or a Turkish coffee is, they are these things:
- Mocha pot: a stovetop device used for making espresso without an espresso machine
- Turkish coffee pot: also a stovetop device; this thing makes some of the strongest coffee you have ever encountered. Turks usually add sugar (this writer doesn’t; but my taste in coffee been described as “coffee like a punch in the face”)
So, wonderful as they are for those of us who love strong coffee, they also produce the highest in-drink levels of cafestol. If you’d like to cut the cafestol (for example, if you are keeping an eye on your LDL), we recommend…
The humble filter coffee
Whether by your favorite filter coffee machine or a pour-over low-tech coffee setup of the kind you could use even without an electricity supply, the filter keeps more than just the coffee grinds out; it keeps the cafestol out too; most of it, anyway, depending on what kind of filter you use, and the grind of the coffee:
Physical characteristics of the paper filter and low cafestol content filter coffee brews
What about instant coffee?
It has very little cafestol in it. It’s up to you whether that’s sufficient reason to choose it over any other form of coffee (this coffee-lover could never)
Want to make any coffee healthier?
This one isn’t about the cafestol, but…
If you take l-theanine (see here for our previous main feature about l-theanine), the l-theanine acts as a moderator and modulator of the caffeine, amongst other benefits:

An apple cider vinegar drink a day? New study shows it might help weight loss
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.
Made from fermented apples and naturally high in acetic acid, apple cider vinegar has been popular in recent years for its purported health benefits – from antibacterial properties to antioxidant effects and potential for helping manage blood sugars.
Its origins as a health tonic stretch much further back. Hippocrates used it to treat wounds, fever and skin sores.
An experimental study, released today, looks into whether apple cider vinegar could be effective for weight loss, reduce blood glucose levels and reduce blood lipids (cholesterol and triglycerides).
The results suggest it could reduce all three – but it might not be as simple as downing an apple cider vinegar drink a day.
What did they do?
A group of scientists in Lebanon did a double-blinded, randomised, clinical trial in a group of overweight and obese young people aged from 12–25 years.
Researchers randomly placed 30 participants in one of four groups. The participants were instructed to consume either 5, 10 or 15ml of apple cider vinegar diluted into 250ml of water each morning before they ate anything for 12 weeks. A control group consumed an inactive drink (a placebo) made (from lactic acid added to water) to look and taste the same.
Typically this sort of study provides high quality evidence as it can show cause and effect – that is the intervention (apple cider vinegar in this case) leads to a certain outcome. The study was also double-blinded, which means neither the participants or the scientists involved with collecting the data knew who was in which group.
So, what did they find?
After a period of three months apple cider vinegar consumption was linked with significant falls in body weight and body mass index (BMI). On average, those who drank apple cider vinegar during that period lost 6–8kg in weight and reduced their BMI by 2.7–3 points, depending on the dose. They also showed significant decreases in the waist and hip circumference.
The authors also report significant decreases in levels of blood glucose, triglycerides, and cholesterol in the apple cider groups. This finding echoes previous studies. The placebo group, who were given water with lactic acid, had much smaller decreases in weight and BMI. There were also no significant decreases in blood glucose and blood lipids.
From animal studies, it is thought the acetic acid in apple cider vinegar may affect the expression of genes involved in burning fats for energy. The new study did not explore whether this mechanism was involved in any weight loss.
Is this good news?
While the study appears promising, there are also reasons for caution.
Firstly, study participants were aged from 12 to 25, so we can’t say whether the results could apply to everyone.
The statistical methods used in the study don’t allow us to confidently say the same amount of weight loss would occur again if the study was done again.
And while the researchers kept records of the participants’ diet and exercise during the study, these were not published in the paper. This makes it difficult to determine if diet or exercise may have had an impact. We don’t know whether participants changed the amount they ate or the types of food they ate, or whether they changed their exercise levels.
The study used a placebo which they tried to make identical in appearance and taste to the active treatment. But people may still be able to determine differences. Researchers may ask participants at the end of a study to guess which group they were in to test the integrity of the placebo. Unfortunately this was not done in this study, so we can’t be certain if the participants knew or not.
Finally, the authors do not report whether anyone dropped out of the study. This could be important and influence results if people who did not lose weight quit due to lack of motivation.
Is that you mother? The enzymes in apple cider vinegar might be health-giving.
ShutterstockAny other concerns?
Apple cider vinegar is acidic and there are concerns it may erode tooth enamel. This can be a problem with any acidic beverages, including fizzy drinks, lemon water and orange juice.
To minimise the risk of acid erosion some dentists recommend the following after drinking acidic drinks:
- rinsing out your mouth with tap water afterwards
- chewing sugar-free gum afterwards to stimulate saliva production
- avoiding brushing your teeth immediately after drinking because it might damage the teeth’s softened top layer
- drink with a straw to minimise contact with the teeth.
Rinsing with water could prevent acid damaging your teeth.
ShutterstockDown the hatch?
This study provides us with some evidence of a link between apple cider vinegar and weight loss. But before health professionals can recommend this as a weight loss strategy we need bigger and better conducted studies across a wider age range.
Such research would need to be done alongside a controlled background diet and exercise across all the participants. This would provide more robust evidence that apple cider vinegar could be a useful aid for weight loss.
Still, if you don’t mind the taste of apple cider vinegar then you could try drinking some for weight loss, alongside a healthy balanced and varied dietary intake. This study does not suggest people can eat whatever they like and drink apple cider vinegar as a way to control weight.

Alpha, beta, theta: what are brain states and brain waves? And can we control them?
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 no shortage of apps and technology that claim to shift the brain into a “theta” state – said to help with relaxation, inward focus and sleep.
But what exactly does it mean to change one’s “mental state”? And is that even possible? For now, the evidence remains murky. But our understanding of the brain is growing exponentially as our methods of investigation improve.
Brain-measuring tech is evolving
Currently, no single approach to imaging or measuring brain activity gives us the whole picture. What we “see” in the brain depends on which tool we use to “look”. There are myriad ways to do this, but each one comes with trade-offs.
We learnt a lot about brain activity in the 1980s thanks to the advent of magnetic resonance imaging (MRI).
Eventually we invented “functional MRI”, which allows us to link brain activity with certain functions or behaviours in real time by measuring the brain’s use of oxygenated blood during a task.
We can also measure electrical activity using EEG (electroencephalography). This can accurately measure the timing of brain waves as they occur, but isn’t very accurate at identifying which specific areas of the brain they occur in.
Alternatively, we can measure the brain’s response to magnetic stimulation. This is very accurate in terms of area and timing, but only as long as it’s close to the surface.
What are brain states?
All of our simple and complex behaviours, as well as our cognition (thoughts) have a foundation in brain activity, or “neural activity”. Neurons – the brain’s nerve cells – communicate by a sequence of electrical impulses and chemical signals called “neurotransmitters”.
Neurons are very greedy for fuel from the blood and require a lot of support from companion cells. Hence, a lot of measurement of the site, amount and timing of brain activity is done via measuring electrical activity, neurotransmitter levels or blood flow.
We can consider this activity at three levels. The first is a single-cell level, wherein individual neurons communicate. But measurement at this level is difficult (laboratory-based) and provides a limited picture.
As such, we rely more on measurements done on a network level, where a series of neurons or networks are activated. Or, we measure whole-of-brain activity patterns which can incorporate one or more so-called “brain states”.
According to a recent definition, brain states are “recurring activity patterns distributed across the brain that emerge from physiological or cognitive processes”. These states are functionally relevant, which means they are related to behaviour.
Brain states involve the synchronisation of different brain regions, something that’s been most readily observed in animal models, usually rodents. Only now are we starting to see some evidence in human studies.
Various kinds of states
The most commonly-studied brain states in both rodents and humans are states of “arousal” and “resting”. You can picture these as various levels of alertness.
Studies show environmental factors and activity influence our brain states. Activities or environments with high cognitive demands drive “attentional” brain states (so-called task-induced brain states) with increased connectivity. Examples of task-induced brain states include complex behaviours such as reward anticipation, mood, hunger and so on.
In contrast, a brain state such as “mind-wandering” seems to be divorced from one’s environment and tasks. Dropping into daydreaming is, by definition, without connection to the real world.
We can’t currently disentangle multiple “states” that exist in the brain at any given time and place. As mentioned earlier, this is because of the trade-offs that come with recording spatial (brain region) versus temporal (timing) brain activity.
Brain states vs brain waves
Brain state work can be couched in terms such as alpha, delta and so forth. However, this is actually referring to brain waves which specifically come from measuring brain activity using EEG.
EEG picks up on changing electrical activity in the brain, which can be sorted into different frequencies (based on wavelength). Classically, these frequencies have had specific associations:
- gamma is linked with states or tasks that require more focused concentration
- beta is linked with higher anxiety and more active states, with attention often directed externally
- alpha is linked with being very relaxed, and passive attention (such as listening quietly but not engaging)
- theta is linked with deep relaxation and inward focus
- and delta is linked with deep sleep.
Brain wave patterns are used a lot to monitor sleep stages. When we fall asleep we go from drowsy, light attention that’s easily roused (alpha), to being relaxed and no longer alert (theta), to being deeply asleep (delta).
Can we control our brain states?
The question on many people’s minds is: can we judiciously and intentionally influence our brain states?
For now, it’s likely too simplistic to suggest we can do this, as the actual mechanisms that influence brain states remain hard to detangle. Nonetheless, researchers are investigating everything from the use of drugs, to environmental cues, to practising mindfulness, meditation and sensory manipulation.
Controversially, brain wave patterns are used in something called “neurofeedback” therapy. In these treatments, people are given feedback (such as visual or auditory) based on their brain wave activity and are then tasked with trying to maintain or change it. To stay in a required state they may be encouraged to control their thoughts, relax, or breathe in certain ways.
The applications of this work are predominantly around mental health, including for individuals who have experienced trauma, or who have difficulty self-regulating – which may manifest as poor attention or emotional turbulence.
However, although these techniques have intuitive appeal, they don’t account for the issue of multiple brain states being present at any given time. Overall, clinical studies have been largely inconclusive, and proponents of neurofeedback therapy remain frustrated by a lack of orthodox support.
Other forms of neurofeedback are delivered by MRI-generated data. Participants engaging in mental tasks are given signals based on their neural activity, which they use to try and “up-regulate” (activate) regions of the brain involved in positive emotions. This could, for instance, be useful for helping people with depression.
Another potential method claimed to purportedly change brain states involves different sensory inputs. Binaural beats are perhaps the most popular example, wherein two different wavelengths of sound are played in each ear. But the evidence for such techniques is similarly mixed.
Treatments such as neurofeedback therapy are often very costly, and their success likely relies as much on the therapeutic relationship than the actual therapy.
On the bright side, there’s no evidence these treatment do any harm – other than potentially delaying treatments which have been proven to be beneficial.

Hazelnuts vs Cashews – 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 hazelnuts to cashews, we picked the hazelnuts.
Why?
It’s close! This one’s interesting…
In terms of macros, hazelnuts have more fiber and fats, while cashews have more protein and carbs. All in all, all good stuff all around; maybe a win for one or the other depending on your priorities. We’d pick hazelnuts here, but your preference may vary.
When it comes to vitamins, hazelnuts have more of vitamins A, B1, B2, B3, B5, B6, B9, C, and E, while cashews have more vitamin K. An easy win for hazelnuts here, and the margins weren’t close.
In the category of minerals, hazelnuts have more calcium, manganese, and potassium, while cashews have more copper, iron, magnesium, phosphorus, selenium, and zinc. This is a win for cashews, but it’s worth noting that cup for cup, both of these nuts provide more than the daily requirement of most of those minerals. This means that in practical terms, it doesn’t matter too much that (for example), while cashews provide 732% of the daily requirement for copper, hazelnuts “only” provide 575%. So while this category remains a victory for cashews, it’s something of a “on paper” thing for the most part.
Adding up the sections (ambivalent + clear win for hazelnuts + nominal win for cashews) means that in total today we’re calling it in favour of hazelnuts… But as ever, enjoy both, because both are good and so is diversity!

The Minimum Method – by Joey Thurman
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.
Trying to squeeze out an extra 0.5% from every effort in life can be exhausting, especially with diminishing marginal returns when it comes to linear increases in effort.
Surely there must be a sweet spot of getting the best returns on the least effort and call it a day?
That’s what this book is about. Thurman examines and explains how to get “the most for least” in various important areas of health, including diet, exercise, sleep, breathwork, recovery, and a chapter specifically on brain health, though of course all the aforementioned things do affect brain health too.
An interesting feature of the book is that at the end of each chapter, he’ll give different advice for different levels of experience/commitment, so that essentially there’s an easy/medium/hard way to proceed each time.
The style is light and personal, without much hard science. The advice given is nonetheless consistent with prevailing scientific consensus, and there are still occasional scientific references throughout, with links to appropriate studies. Mostly though, the focus is on being practical.
Bottom line: if you’ve been looking for a “most for least” way of going about health, this is a fine option.

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.
Cabbage is an underrated vegetable for its many nutrients and its culinary potential—here’s a great way to make it a delectable starter or respectable side.
You will need
- 1 medium white cabbage, sliced into 1″ thick slabs
- 1 tbsp extra-virgin olive oil
- 1 tbsp caraway seeds
- 1 tsp black pepper
- ½ tsp turmeric
- ¼ tsp MSG or ½ tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Combine the non-cabbage ingredients in a small bowl, whisking to mix thoroughly—with a tiny whisk if you have one, but a fork will work if necessary.
3) Arrange the cabbage slices on a lined baking tray and brush the seasoning-and-oil mixture over both sides of each slice.
4) Roast for 20–25 minutes until the cabbage is tender and beginning to caramelize.
5) Serve warm.
Enjoy!
