Our Verdict
When comparing pear to prickly pear, we picked the prickly.
Why?
Both of these fruits are fine and worthy choices, but the prickly pear wins out in nutritional density.
Looking at the macros to start with, the prickly pear is higher in fiber and lower in carbs, resulting in a much lower glycemic index. However, non-prickly pears are already low GI, so this is not a huge matter. Whether it’s pear’s GI of 38 or prickly pear’s GI of 7, you’re unlikely to experience a glucose spike.
In the category of vitamins, pear has a little more of vitamins B5, B9, E, K, and choline, but the margins are tiny. On the other hand, prickly pear has more of vitamins A, B1, B2, B3, B6, and C, with much larger margins of difference (except vitamin B1; that’s still quite close). Even before taking margins of difference into account, this is a slight win for prickly pear.
When it comes to minerals, things are more pronounced; pear has more manganese, while prickly pear has more calcium, iron, magnesium, phosphorus, potassium, selenium, and zinc.
In short, both pears are great (so do enjoy the pair), but prickly pear is the clear winner where one must be declared.

Even small diet tweaks can lead to sustainable 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.
It’s a well-known fact that to lose weight, you either need to eat less or move more. But how many calories do you really need to cut out of your diet each day to lose weight? It may be less than you think.
To determine how much energy (calories) your body requires, you need to calculate your total daily energy expenditure (TDEE). This is comprised of your basal metabolic rate (BMR) – the energy needed to sustain your body’s metabolic processes at rest – and your physical activity level. Many online calculators can help determine your daily calorie needs.
If you reduce your energy intake (or increase the amount you burn through exercise) by 500-1,000 calories per day, you’ll see a weekly weight loss of around one pound (0.45kg).
But studies show that even small calorie deficits (of 100-200 calories daily) can lead to long-term, sustainable weight-loss success. And although you might not lose as much weight in the short-term by only decreasing calories slightly each day, these gradual reductions are more effective than drastic cuts as they tend to be easier to stick with.
Small diet changes can still lead to weight loss in the long run. Monkey Business Images/ Shutterstock Hormonal changes
When you decrease your calorie intake, the body’s BMR often decreases. This phenomenon is known as adaptive thermogenesis. This adaptation slows down weight loss so the body can conserve energy in response to what it perceives as starvation. This can lead to a weight-loss plateau – even when calorie intake remains reduced.
Caloric restriction can also lead to hormonal changes that influence metabolism and appetite. For instance, thyroid hormones, which regulate metabolism, can decrease – leading to a slower metabolic rate. Additionally, leptin levels drop, reducing satiety, increasing hunger and decreasing metabolic rate.
Ghrelin, known as the “hunger hormone”, also increases when caloric intake is reduced, signalling the brain to stimulate appetite and increase food intake. Higher ghrelin levels make it challenging to maintain a reduced calorie diet, as the body constantly feels hungrier.
Insulin, which helps regulate blood sugar levels and fat storage, can improve in sensitivity when we reduce calorie intake. But sometimes, insulin levels decrease instead, affecting metabolism and leading to a reduction in daily energy expenditure. Cortisol, the stress hormone, can also spike – especially when we’re in a significant caloric deficit. This may break down muscles and lead to fat retention, particularly in the stomach.
Lastly, hormones such as peptide YY and cholecystokinin, which make us feel full when we’ve eaten, can decrease when we lower calorie intake. This may make us feel hungrier.
Fortunately, there are many things we can do to address these metabolic adaptations so we can continue losing weight.
Weight loss strategies
Maintaining muscle mass (either through resistance training or eating plenty of protein) is essential to counteract the physiological adaptations that slow weight loss down. This is because muscle burns more calories at rest compared to fat tissue – which may help mitigate decreased metabolic rate.
Portion control is one way of decreasing your daily calorie intake. Fevziie/ Shutterstock Gradual caloric restriction (reducing daily calories by only around 200-300 a day), focusing on nutrient-dense foods (particularly those high in protein and fibre), and eating regular meals can all also help to mitigate these hormonal challenges.
But if you aren’t someone who wants to track calories each day, here are some easy strategies that can help you decrease daily calorie intake without thinking too much about it:
1. Portion control: reducing portion sizes is a straightforward way of reducing calorie intake. Use smaller plates or measure serving sizes to help reduce daily calorie intake.
2. Healthy swaps: substituting high-calorie foods with lower-calorie alternatives can help reduce overall caloric intake without feeling deprived. For example, replacing sugary snacks with fruits or swapping soda with water can make a substantial difference to your calorie intake. Fibre-rich foods can also reduce the calorie density of your meal.
3. Mindful eating: practising mindful eating involves paying attention to hunger and fullness cues, eating slowly, and avoiding distractions during meals. This approach helps prevent overeating and promotes better control over food intake.
4. Have some water: having a drink with your meal can increase satiety and reduce total food intake at a given meal. In addition, replacing sugary beverages with water has been shown to reduce calorie intake from sugars.
4. Intermittent fasting: restricting eating to specific windows can reduce your caloric intake and have positive effects on your metabolism. There are different types of intermittent fasting you can do, but one of the easiest types is restricting your mealtimes to a specific window of time (such as only eating between 12 noon and 8pm). This reduces night-time snacking, so is particularly helpful if you tend to get the snacks out late in the evening.
Long-term behavioural changes are crucial for maintaining weight loss. Successful strategies include regular physical activity, continued mindful eating, and periodically being diligent about your weight and food intake. Having a support system to help you stay on track can also play a big role in helping you maintain weight loss.
Modest weight loss of 5-10% body weight in people who are overweight or obese offers significant health benefits, including improved metabolic health and reduced risk of chronic diseases. But it can be hard to lose weight – especially given all the adaptations our body has to prevent it from happening.
Thankfully, small, sustainable changes that lead to gradual weight loss appear to be more effective in the long run, compared with more drastic lifestyle changes.

Ideal Blood Pressure Numbers Explained
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝Maybe I missed it but the study on blood pressure did it say what the 2 numbers should read ideally?❞
We linked it at the top of the article rather than including it inline, as we were short on space (and there was a chart rather than a “these two numbers” quick answer), but we have a little more space today, so:
Category Systolic (mm Hg) Diastolic (mm Hg) Normal < 120 AND < 80 Elevated 120 – 129 AND < 80 Stage 1 – High Blood Pressure 130 – 139 OR 80 – 89 Stage 2 – High Blood Pressure 140 or higher OR 90 or higher Hypertensive Crisis Above 180 AND/OR Above 120 To oversimplify for a “these two numbers” answer, under 120/80 is generally considered good, unless it is under 90/60, in which case that becomes hypotension.
Hypotension, the blood pressure being too low, means your organs may not get enough oxygen and if they don’t, they will start shutting down.
To give you an idea how serious this, this is the closed-circuit equivalent of the hypovolemic shock that occurs when someone is bleeding out onto the floor. Technically, bleeding to death also results in low blood pressure, of course, hence the similarity.
So: just a little under 120/80 is great.

Carrot vs Kale – 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 carrot to kale, we picked the kale.
Why?
These are both known as carotene-containing heavyweights, but kale emerges victorious:
In terms of macros, carrot has more carbs while kale has more protein and fiber. An easy win there for kale.
When it comes to vitamins, both are great! But, carrots contain more of vitamins A, B5, and choline, whereas kale contains more of vitamins B1, B2, B3, B6, B9, C, E, and K. And while carrot’s strongest point is vitamin A, a cup of carrots contains around 10x the recommended daily dose of vitamin A, whereas a cup of kale contains “only” 6x the recommended daily dose of vitamin A. So, did we really need the extra in carrots? Probably not. In any case, kale already won on overall vitamin coverage, by a long way.
In the category of minerals, kale again sweeps. On the one hand, carrots contain more sodium. On the other hand, kale contains a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Not a tricky choice!
But don’t be fooled: carrots really are a nutritional powerhouse and a great food. Kale is just better—nutritionally speaking, in any case. If you’re making a carrot cake, please don’t try substituting kale; it will not work 😉

You may be familiar with the lead author of this book, Dr. David Perlmutter, as a big name in the world of preventative healthcare. A lot of his work has focused specifically on carbohydrate metabolism, and he is as associated with grains and he is with brains. This book focuses on the latter.
Dr. Perlmutter et al. take a methodical look at all that is ailing our brains in this modern world, and systematically lay out a plan for improving each aspect.
The advice is far from just dietary, though the chapter on diet takes a clear stance:
❝The food you eat and the beverages you drink change your emotions, your thoughts, and the way you perceive the world❞
The style is explanatory, and the book can be read comfortably as a “sit down and read it cover to cover” book; it’s an enjoyable, informative, and useful read.
Bottom line: if you’d like to give your brain a gentle overhaul, this is the one-stop-shop book to give you the tools to do just that.

Tips For Avoiding/Managing Rheumatoid Arthritis
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.
Avoiding/Managing Rheumatoid Arthritis
Arthritis is the umbrella term for a cluster of joint diseases involving inflammation of the joints, hence “arthr-” (joint) “-itis” (suffix used to denote inflammation). These are mostly, but not all, autoimmune diseases, in which the body’s immune system mistakenly attacks our own joints.
Inflammatory vs Non-Inflammatory Arthritis
Arthritis is broadly divided into inflammatory arthritis and non-inflammatory arthritis.
You may be wondering: how does one get non-inflammatory inflammation of the joints?
The answer is, in “non-inflammatory” arthritis, such as osteoarthritis, the damage comes first (by general wear-and-tear) and inflammation generally follows as part of the symptoms, rather than the cause. So the name can be a little confusing. In the case of osteo- and other “non-inflammatory” forms of arthritis, you definitely still want to keep your inflammation at bay as best you can, but it’s not as absolutely critical a deal as it is for “inflammatory” forms of arthritis.
We’ll tackle the beast that is osteoarthritis another day, however.
Today we’re going to focus on…
Rheumatoid Arthritis
This is the most common of the autoimmune forms of arthritis. Some quick facts:
- It affects a little under 1% of the global population, but the older we get, the more likely it becomes
- Early onset of rheumatoid arthritis is most likely to show up around the age of 50 (but it can show up at any age)
- However, incidence (not onset) of rheumatoid arthritis peaks in the 70s age bracket
- It is 2–4 times more common in women than in men
- Approximately one third of people stop work within two years of its onset, and this increases thereafter.
Well, that sounds gloomy.
Indeed it’s not fun. There’s a lot of stiffness and aching of joints (often with swelling too), loss of joint function can be common, and then there are knock-on effects like fatigue, weakness, and loss of appetite.
Beyond that it’s an autoimmune disorder, its cause is not known, and there is no known cure.
Is there any good news?
If you don’t have rheumatoid arthritis at the present time, you can reduce your risk factors in several ways:
- Having an anti-inflammatory diet. Get plenty of fiber, greens, and berries. Fatty fish is great too, as are oily nuts. On the other side of things, high consumption of salt, sugar, alcohol, and red meat are associated with a greater risk of developing rheumatoid arthritis.
- Not smoking. Smoking is bad for pretty much everything, including your chances of developing rheumatoid arthritis.
- Not being obese. This one may be more a matter of correlation than causation, because of the dietary factors (if one eats an anti-inflammatory diet, obesity is less likely), but the association is there.
There are other risk factors that are harder to control, such as genetics, age, sex, and having a mother who smoked.
See: Genetic and environmental risk factors for rheumatoid arthritis
What if I already have rheumatoid arthritis?
If you already have rheumatoid arthritis, it becomes a matter of symptom management.
First, reduce inflammation any (reasonable) way you can. We did a main feature on this before, so we’ll just drop that again here:
Next, consider the available medications. Your doctor may or may not have discussed all of the options with you, so be aware that there are more things available than just pain relief. To talk about them all would require a whole main feature, so instead, here’s a really well-compiled list, along with explanations about each of them, up to date as of this year:
Rheumatoid Arthritis Medication List (And What They Do, And How)
Finally, consider other lifestyle adjustments to manage your symptoms. These include:
- Exercise—gently, though! You do not want to provoke a flare-up, but you do want to maintain your mobility as best you can. There’s a use-it-or-lose-it factor here. Swimming and yoga are great options, as is tai chi. You may want to avoid exercises that involve repetitive impacts to your joints, like running.
- Rest—while keeping mobility going. Get good sleep at night (this is important), but don’t make your bed your new home, or your mobility will quickly deteriorate.
- Hot & cold—both can help, and alternating them can reduce inflammation and stiffness by improving your body’s ability to respond appropriately to these stimuli rather than getting stuck in an inappropriate-response state of inflammation.
- Mobility aids—if it helps, it helps. Maybe you only need something during a flare-up, but when that’s the case, you want to be as gentle on your body as possible while keeping moving, so if crutches, handrails etc help, then by all means get them and use them.
- Go easy on the use of braces, splints, etc—these can offer short-term relief, but at a long term cost of loss of mobility. Only you can decide where to draw the line when it comes to that trade-off.

Head Over Hips
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’ve written before about managing osteoarthritis (or ideally: avoiding it, but that’s not always an option on the table, of course), so here’s a primer/refresher before we get into the meat of today’s article:
Avoiding/Managing Osteoarthritis
When the head gets in the way
Research shows that the problem with recovery in cases of osteoarthritis of the hip is in fact often not the hip itself, but rather, the head:
❝In fact, the stronger your muscles are, the more protected your joint is, and the less pain you will experience.
Our research has shown that people with hip osteoarthritis were unable to activate their muscles as efficiently, irrespective of strength.
Basically, people with hip arthritis are unable to activate their muscles properly because the brain is actively putting on the brake to stop them from using the muscle.❞
This is a case of a short-term protective response being unhelpful in the long-term. If you injure yourself, your brain will try to inhibit you from exacerbating that injury, such as by (for example) disobliging you from putting weight on an injured joint.
This is great if you merely twisted an ankle and just need to sit back and relax while your body works its healing magic, but it’s counterproductive if it’s a chronic issue like osteoarthritis. In such (i.e. chronic) cases, avoidance of use of the joint will simply cause atrophy of the surrounding muscle and other tissues, leading to more of the very wear-and-tear that led to the osteoarthritis in the first place.
So… How to deal with that?
You probably can exercise
It’s easy to get caught between the dichotomy of “exercise and inflame your joints” vs “rest and your joints seize up”, which is not pleasant.
However, the trick lies in how you exercise, per joint type:
When Bad Joints Stop You From Exercising (5 Things To Change)
…which to be clear, isn’t a case of “avoid using the joint that’s bad”, but is rather “use it in this specific way, so that it gets stronger without doing it more damage in the process”.
Which is exactly what is needed!
