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
❝I would love to see an article about heat dehydrated illness….so much of the US is under hot conditions. I had an fainting sweating episode and now trying to recoup from it. What should we do? Drink water,rest…???❞
We have done some of this, but it’s always a good one to revisit! Last summer (N. Hemisphere summer), we wrote this:
Stay Safe From Heat Exhaustion & Heatstroke!
…and this year, it’s getting hotter still (and is already the hottest summer on record), with certainly much of the US seriously affected, as you say. Next year, it will probably be worse again; climate change is getting predictable like that, and likely will continue until fixed. We are but a health science publication, so we can’t fix the world’s climate, but we can reiterate the above advice, and urge everyone to take it seriously.
Note: heat exhaustion and heatstroke kill. Yes, we’re including heat exhaustion in that, because by the time you get heat exhaustion, you’re often not in the best state of mind to take the correct steps to avoid the heatstroke that follows.
To think otherwise would be akin to thinking “falling never killed anyone; it’s only when you stop falling that it’s dangerous”.
This summer, we did also write this more niche article:
…whose advice won’t apply to everyone, but will be helpful to some, and honestly, some of that advice does go for everyone.
One thing we didn’t write about in those articles that we’ll add here:
Humidity is dangerous:
- Dry heat: you sweat, the sweat evaporates, cooling you. As well as losing heat, you’ve also now lost water and salts, which you’ll need to replenish, but your body is operating correctly.
- Humid heat: you sweat, and now you are just sweaty until further notice. It doesn’t evaporate because the surrounding humidity doesn’t provide the physics for that. Not only are you not losing heat through evaporating sweat, but also, if you’re wearing clothes, that’s now an insulating layer you’re wearing.
…so that means, watch the humidity as carefully as you watch the temperature, and when it’s high, get extra serious about finding ways to keep yourself cool (e.g. shade, rest, cooling showers etc if you can, that kind of thing).
Take care!

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.

Parents are increasingly saying their child is ‘dysregulated’. What does that actually mean?
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.
Welcome aboard the roller coaster of parenthood, where emotions run wild, tantrums reign supreme and love flows deep.
As children reach toddlerhood and beyond, parents adapt to manage their child’s big emotions and meltdowns. Parenting terminology has adapted too, with more parents describing their child as “dysregulated”.
But what does this actually mean?
ShUStudio/Shutterstock More than an emotion
Emotional dysregulation refers to challenges a child faces in recognising and expressing emotions, and managing emotional reactions in social settings.
This may involve either suppressing emotions or displaying exaggerated and intense emotional responses that get in the way of the child doing what they want or need to do.
“Dysregulation” is more than just feeling an emotion. An emotion is a signal, or cue, that can give us important insights to ourselves and our preferences, desires and goals.
An emotionally dysregulated brain is overwhelmed and overloaded (often, with distressing emotions like frustration, disappointment and fear) and is ready to fight, flight or freeze.
Developing emotional regulation
Emotion regulation is a skill that develops across childhood and is influenced by factors such as the child’s temperament and the emotional environment in which they are raised.
In the stage of emotional development where emotion regulation is a primary goal (around 3–5 years old), children begin exploring their surroundings and asserting their desires more actively.
A child’s temperament and upbringing affect how they regulate emotions. bluedog studio/Shutterstock It’s typical for them to experience emotional dysregulation when their initiatives are thwarted or criticised, leading to occasional tantrums or outbursts.
A typically developing child will see these types of outbursts reduce as their cognitive abilities become more sophisticated, usually around the age they start school.
Express, don’t suppress
Expressing emotions in childhood is crucial for social and emotional development. It involves the ability to convey feelings verbally and through facial expressions and body language.
When children struggle with emotional expression, it can manifest in various ways, such as difficulty in being understood, flat facial expressions even in emotionally charged situations, challenges in forming close relationships, and indecisiveness.
Several factors, including anxiety, attention-deficit hyperactivity disorder (ADHD), autism, giftedness, rigidity and both mild and significant trauma experiences, can contribute to these issues.
Common mistakes parents can make is dismissing emotions, or distracting children away from how they feel.
These strategies don’t work and increase feelings of overwhelm. In the long term, they fail to equip children with the skills to identify, express and communicate their emotions, making them vulnerable to future emotional difficulties.
We need to help children move compassionately towards their difficulties, rather than away from them. Parents need to do this for themselves too.
Caregiving and skill modelling
Parents are responsible for creating an emotional climate that facilitates the development of emotion regulation skills.
Parents’ own modelling of emotion regulation when they feel distressed. The way they respond to the expression of emotions in their children, contributes to how children understand and regulate their own emotions.
Children are hardwired to be attuned to their caregivers’ emotions, moods, and coping as this is integral to their survival. In fact, their biggest threat to a child is their caregiver not being OK.
Unsafe, unpredictable, or chaotic home environments rarely give children exposure to healthy emotion expression and regulation. Children who go through maltreatment have a harder time controlling their emotions, needing more brainpower for tasks that involve managing feelings. This struggle could lead to more problems with emotions later on, like feeling anxious and hypervigilant to potential threats.
Recognising and addressing these challenges early on is essential for supporting children’s emotional wellbeing and development.
A dysregulated brain and body
When kids enter “fight or flight” mode, they often struggle to cope or listen to reason. When children experience acute stress, they may respond instinctively without pausing to consider strategies or logic.
If your child is in fight mode, you might observe behaviours such as crying , clenching fists or jaw, kicking, punching, biting, swearing, spitting or screaming.
In flight mode, they may appear restless, have darting eyes, exhibit excessive fidgeting, breathe rapidly, or try to run away.
A shut-down response may look like fainting or a panic attack.
When a child feels threatened, their brain’s frontal lobe, responsible for rational thinking and problem-solving, essentially goes offline.
The amygdala, shown here in red, triggers survival mode. pikovit/Shutterstock This happens when the amygdala, the brain’s alarm system, sends out a false alarm, triggering the survival instinct.
In this state, a child may not be able to access higher functions like reasoning or decision-making.
While our instinct might be to immediately fix the problem, staying present with our child during these moments is more effective. It’s about providing support and understanding until they feel safe enough to engage their higher brain functions again.
Reframe your thinking so you see your child as having a problem – not being the problem.
Tips for parents
Take turns discussing the highs and lows of the day at meal times. This is a chance for you to be curious, acknowledge and label feelings, and model that you, too, experience a range of emotions that require you to put into practice skills to cope and has shown evidence in numerous physical, social-emotional, academic and behavioural benefits.
Talk about your day over dinner. Monkey Business Images/Shutterstock Spending even small amounts (five minutes a day!) of quality one-on-one time with your child is an investment in your child’s emotional wellbeing. Let them pick the activity, do your best to follow their lead, and try to notice and comment on the things they do well, like creative ideas, persevering when things are difficult, and being gentle or kind.
Take a tip from parents of children with neurodiversity: learn about your unique child. Approaching your child’s emotions, temperament, and behaviours with curiosity can help you to help them develop emotion regulation skills.
When to get help
If emotion dysregulation is a persistent issue that is getting in the way of your child feeling happy, calm, or confident – or interfering with learning or important relationships with family members or peers – talk to their GP about engaging with a mental health professional.
Many families have found parenting programs helpful in creating a climate where emotions can be safely expressed and shared.
Remember, you can’t pour from an empty cup. Parenting requires you to be your best self and tend to your needs first to see your child flourish.

What you need to know about H5N1 bird flu
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.
On May 30, the Centers for Disease Control and Prevention reported that a Michigan dairy worker tested positive for H5N1 bird flu. It was the fourth person to test positive for H5N1 in the United States, following another recent case in Michigan, an April case in Texas, and an initial case in Colorado in 2022.
H5N1 bird flu has been spreading among bird species in the U.S. since 2021, killing millions of wild birds and poultry. In late March 2024, H5N1 bird flu was found in cows for the first time, causing an outbreak in dairy cows across several states.
U.S. public health officials and researchers are particularly concerned about this outbreak because the virus has infected cows and other mammals and has spread from a cow to a human for the first time.
This bird flu strain has shown to not only make wild mammals, including marine mammals and bears, very sick but to also cause high rates of death among species, says Jane Sykes, professor of small animal medicine at the University of California, Davis, School of Veterinary Medicine.
“And now that it has been found in cattle, [it] raises particular concern for spread to all the animal species, including people,” adds Sykes.
Even though the risk for human infection is low and there has never been human-to-human transmission of H5N1, there are several actions you can take to stay protected. Read on to learn more about H5N1 bird flu and the current outbreak.
What is H5N1?
H5N1 is a type of influenza virus that most commonly affects birds, causing them severe respiratory illness and death.
The H5N1 strain first emerged in China in the 1990s, and it has continued to spread around the world since then. In 1997, the virus spread from animals to humans in Hong Kong for the first time, infecting 18 people, six of whom died.
Since 2020, the H5N1 strain has caused “an unprecedented number of deaths in wild birds and poultry in many countries,” according to the World Health Organization.
Even though bird flu is rare in humans, an H5N1 infection can cause mild to severe illness and can be fatal in some cases. It can cause eye infection, upper respiratory symptoms, and pneumonia.
What do we know about the 2024 human cases of H5N1 in the U.S.?
The Michigan worker who tested positive for H5N1 in late May is a dairy worker who was exposed to infected livestock. They were the first to experience respiratory symptoms—including a cough without a fever—during the current outbreak. They were given an antiviral and the CDC says their symptoms are resolving.
The Michigan farm worker who tested positive earlier in May only experienced eye-related symptoms and has already recovered. And the dairy worker who tested positive for the virus in Texas in April only experienced eye redness as well, was treated with an antiviral medication for the flu, and is recovering.
Is H5N1 bird flu in the milk we consume?
The Food and Drug Administration has found traces of H5N1 bird flu virus in raw or unpasteurized milk. However, pasteurized milk is safe to drink.
Pasteurization, the process of heating milk to high temperatures to kill harmful bacteria (which the majority of commercially sold milk goes through), deactivates the virus. In 20 percent of pasteurized milk samples, the FDA found small, inactive (not live nor infectious) traces of the virus, but these fragments do not make pasteurized milk dangerous.
In a recent Infectious Diseases Society of America briefing, Dr. Maximo Brito, a professor at the University of Illinois College of Medicine, said that it’s important for people to avoid “drinking unpasteurized or raw milk [because] there are other diseases, not only influenza, that could be transmitted by drinking unpasteurized milk.”
What can I do to prevent bird flu?
While the risk of H5N1 infection in humans is low, people with exposure to infected animals (like farmworkers) are most at risk. But there are several actions you can take to stay protected.
One of the most important things, according to Sykes, is taking the usual precautions we’ve taken with COVID-19 and other respiratory viruses, including frequent handwashing, especially before eating.
“Handwashing and mask-wearing [are important], just as we learned from the pandemic,” Sykes adds. “And it’s not wearing a mask at all times, but thinking about high-risk situations, like when you’re indoors in a crowded environment, where transmission of respiratory viruses is much more likely to occur.”
There are other steps you can take to prevent H5N1, according to the CDC:
- Avoid direct contact with sick or dead animals, including wild birds and poultry.
- Don’t touch surfaces that may have been contaminated with animal poop, saliva, or mucus.
- Cook poultry and eggs to an internal temperature of 165 degrees Fahrenheit to kill any bacteria or virus, including H5N1. Generally, avoid eating undercooked food.
- Avoid consuming unpasteurized or raw milk or products like cheeses made with raw milk.
- Avoid eating uncooked or undercooked food.
- Poultry and livestock farmers and workers and bird flock owners should wear masks and other personal protective equipment “when in direct or close physical contact with sick birds, livestock, or other animals; carcasses; feces; litter; raw milk; or surfaces and water that might be contaminated with animal excretions from potentially or confirmed infected birds, livestock, or other animals.” (The CDC has more recommendations for this population here.)
Is there a vaccine for H5N1?
The CDC said there are two candidate H5N1 vaccines ready to be made and distributed in case the virus starts to spread from person to person, and the country is now moving forward with plans to produce millions of vaccine doses.
The FDA has approved several bird flu vaccines since 2007. The U.S. has flu vaccines in stockpile through the National Pre-Pandemic Influenza Vaccine Stockpile program, which allows for quick response as strains of the flu virus evolve.
Could this outbreak become a pandemic?
Scientists and researchers are concerned about the possibility of H5N1 spreading among people and causing a pandemic. “Right now, the risk is low, but as time goes on, the potential for mutation to cause widespread human infection increases,” says Sykes.
“I think this virus jumping into cows has shown the urgency to keep tracking [H5N1] a lot more closely now,” Peter Halfmann, research associate professor at the University of Wisconsin-Madison’s Influenza Research Institute tells PGN. “We have our eyes on surveillance now. … We’re keeping a much closer eye, so it’s not going to take us by surprise.”

The Sweet Truth About Diabetes
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 Confusion About Diabetes!
For those readers who are not diabetic, nor have a loved one who is diabetic, nor any other pressing reason to know these things, first a quick 101 rundown of some things to understand the rest of today’s main feature:
- Blood sugar levels: how much sugar is in the blood, measured in mg/dL or mmol/L
- Hyperglycemia or “hyper” for short: too much sugar in the blood
- Hypoglycemia or “hypo” for short: too little sugar in the blood
- Insulin: a hormone that acts as a gatekeeper to allow sugar to pass, or not pass, into various parts of the body
- Type 1 diabetes (sometimes capitalized, and/or abbreviated to “T1D”) is an autoimmune disorder that prevents the pancreas from being able to supply the body with insulin. This means that taking insulin consistently is necessary for life.
- Type 2 diabetes is a matter of insulin resistance. The pancreas produces plenty of insulin, but the body has become desensitized to it, so it doesn’t work properly. Taking extra insulin may sometimes be necessary, but for many people, it can be controlled by means of a careful diet and other lifestyle factors.
With that in mind, on to some very popular myths…
Diabetes is caused by having too much sugar
While sugar is not exactly a health food, it’s not the villain of this story either.
- Type 1 diabetes has a genetic basis, triggered by epigenetic factors unrelated to sugar.
- Type 2 diabetes comes from a cluster of risk factors which, together, can cause a person to go through pre-diabetes and acquire type 2 diabetes.
- Those risk factors include:
- A genetic predisposition
- A large waist circumference
- (this is more relevant than BMI or body fat percentage)
- High blood pressure
- A sedentary lifestyle
- Age (the risk starts rising at 35, rises sharply at 45, and continues upwards with increasing age)
- Those risk factors include:
Read more: Risk Factors for Type 2 Diabetes
Diabetics can’t have sugar
While it’s true that diabetics must be careful about sugar (and carbs in general), it’s not to say that they can’t have them… just: be mindful and intentional about it.
- Type 1 diabetics will need to carb-count in order to take the appropriate insulin bolus. Otherwise, too little insulin will result in hyperglycemia, or too much insulin will result in hypoglycemia.
- Type 2 diabetics will often be able to manage their blood sugar levels with diet alone, and slow-release carbs will make this easier.
In either case, having quick release sugars will increase blood sugar levels (what a surprise), and sometimes (such as when experiencing a hypo), that’s what’s needed.
Also, when it comes to sugar, a word on fruit:
Not all fruits are equal, and some fruits can help maintain stable blood sugar levels! Read all about it:
Fruit Intake to Prevent and Control Hypertension and Diabetes
Artificial sweeteners are must-haves for diabetics
Whereas sugar is a known quantity to the careful diabetic, some artificial sweeteners can impact insulin sensitivity, causing blood sugars to behave in unexpected ways. See for example:
The Impact of Artificial Sweeteners on Body Weight Control and Glucose Homeostasis
If a diabetic person is hyper, they should exercise to bring their blood sugar levels down
Be careful with this!
- In the case of type 2 diabetes, it may (or may not) help, as the extra sugar may be used up.
- Type 1 diabetes, however, has a crucial difference. Because the pancreas isn’t making insulin, a hyper (above a certain level, anyway) means more insulin is needed. Exercising could do more harm than good, as unlike in type 2 diabetes, the body has no way to use that extra sugar, without the insulin to facilitate it. Exercising will just pump the syrupy hyperglycemic blood around the body, potentially causing damage as it goes (all without actually being able to use it).
There are other ways this can be managed that are outside of the scope of this newsletter, but “be careful” is rarely a bad approach.

I want to eat healthily. So why do I crave sugar, salt and carbs?
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 all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.
So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?
There are many reasons for craving specific foods, but let’s focus on four common ones:
1. Blood sugar crashes
Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.
Neurons responding to sugar are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.
In the long term, research suggests a high-sugar diet can affect mood, digestion and inflammation in the gut.
While there’s a lot of variation between individuals, regularly eating sugary and high-carb foods can lead to rapid spikes and crashes in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.
2. Drops in dopamine and serotonin
Certain neurotransmitters, such as dopamine, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.
Serotonin, the feel-good hormone, suppresses appetite. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more carb-rich snacks in the afternoon.
Do you get 3pm sugar cravings? Serotonin could play a role.
Marcus Aurelius/PexelsLow carb diets may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for anxiety and depression.
Compared to men, women tend to crave more carb rich foods. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual symptoms and could be linked to reduced serotonin levels.
3. Loss of fluids and drops in blood sugar and salt
Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, depletes insulin levels, decreasing sodium and water retention.
Very low-carb diets, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.
Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.
4. High levels of stress or emotional turmoil
Stress, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.
The stress hormone cortisol, in particular, can drive cravings for sweet comfort foods.
A 2001 study of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.
A more recent study found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.
What can you do about cravings?
Here are four tips to curb cravings:
1) don’t cut out whole food groups. Aim for a well-balanced diet and make sure you include:
- sufficient protein in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on breakfast and lunch and an overall daily protein intake of at least 0.8g per kg of body weight for muscle health
- fibre-rich foods, such as vegetables and whole grains. These make you feel full and stabilise your blood sugar levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats
2) manage your stress levels. Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising mindful eating, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating
3) get enough sleep. Aim for seven to eight hours of quality sleep per night, with a minimum of seven hours. Lack of sleep can disrupt hormones that regulate hunger and cravings
4) control your portions. If you decide to indulge in a treat, control your portion size to avoid overindulging.
Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.
