How To Rebuild Your Cartilage

We’ve covered before the topic of wear-and-tear on joints such as:
Avoiding/Managing Osteoarthritis
But what of cartilage, in particular? A common belief is “once it’s gone, it’s gone”, but that’s not quite right.
Cartilage is living tissue (metabolically active, with living cells). Within this tissue, specialist cells called chondrocytes produce extracellular cartilage matrix and collagen fibers, which provide smooth joint gliding as well as shock absorption.
Is exercise good or bad for cartilage?
Yes, yes it is. Exercise is good or bad for cartilage depending on the details:
- High-impact exercise e.g. running, jumping) places stress on cartilage, which is broadly bad
- However, impact loading strengthens the subchondral bone plate (layer under cartilage)
Strengthening this bone layer can help in long-term adaptation for high-impact sports.

So, how to do that without wiping out your cartilage first?
Building up
A gradual process is what’s called-for here:
- Start with cyclic, non-impact moderate resistance exercises (e.g. cycling, rowing, swimming).
- Gradually add soft-impact loading (e.g. fast walking, soft jogging).
- Incorporate strength training to improve overall joint stability (e.g. leg press, for lower body joints)
- Slowly transition to running and jumping over a long period to allow tissues to adapt.
How exactly you go about that is a matter of personal taste, but here are some illustrative examples:
- Indoor* cycling
- Cross trainer
- Leg press machine
- Tennis
*Why indoor? It’s so that you can control the resistance level at the twist of a knob, and get on and off when you want.
See also: Treadmill vs Road ← for similar considerations when it comes to walking/running. Outdoor definitely has its advantages, but so does indoor!
And the very related: How To Do HIIT (Without Wrecking Your Body)
Note that HIIT is High Intensity Interval Training, not High Impact Interval Training!
Strength from the inside
One of the most important things for cartilage is collagen. You can supplement that, or if you’re vegetarian/vegan, you can take its constituent parts to improve your own synthesis of it.

Another supplement that can be helpful is glucosamine & chondroitin, which is best taken alongside a good omega-3 intake:

As The Summer Gets Hotter Still…

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!

❝Great newsletter. Am taking turmeric for inflammation of hips and feet. Works like magic. Would like to know how it works, and what tumeric is best combined with – also whether there any risks in longterm use.❞
Glad you’re enjoying! As for turmeric, it sure is great, isn’t it? To answer your questions in a brief fashion:
- How it works: it does a lot of things, but perhaps its most key feature is its autoxidative metabolites that mediate its anti-inflammatory effect. This, it slows or inhibits oxidative stress that would otherwise cause inflammation, increase cancer risk, and advance aging.
- Best combined with: black pepper
- Any risks in long-term use: there are no known risks in long-term use ← that’s just one study, but there are lots. Some studies were prompted by reported hepatotoxicity of curcumin supplements, but a) the reports themselves seem to be without evidence b) the reported hepatoxicity was in relation to contaminants in the supplements, not the curcumin itself c) clinical trials were unable to find any hepatotoxicity (or other) risks anyway. Here’s an example of such a study.

❝This push for longevity is appealing but watching my mother in her nineties is a life I’m not looking forward to. Healthy longevity, yes, but longevity for the sake of a longer life? No thank you.❞
Yes, you’re quite right, that’s exactly the point! Assuming we live to die of age-related conditions (i.e., we do not suffer a fatal accident or incident in our younger years), those unfun last years are coming whether they come at 75 or 95. Or earlier or later, because that can absolutely happen too!
For example: nearly 10% of Americans over 65 have difficulty with self-care
As a rule, and we’ve covered some of the science of this previously, having at least 4 out of 5 of the “big 5” lifestyle factors (diet, exercise, sleep, low-or-zero alcohol, not smoking) not only extends life, but specifically extends the healthspan, i.e. the count of healthy life-years that precedes final age-related decline.

Why Zebras Don’t Get Ulcers – by Dr. Robert M. Sapolsky
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.
The book does kick off with a section that didn’t age well—he talks of the stress induced globally by the Spanish Flu pandemic of 1918, and how that kind of thing just doesn’t happen any more. Today, we have much less existentially dangerous stressors!
However, the fact we went and had another pandemic really only adds weight to the general arguments of the book, rather than detracting.
We are consistently beset by “the slings and arrows of outrageous fortune” as Shakespeare would put it, and there’s a reason (or twenty) why many people go grocery-shopping with the cortisol levels of someone being hunted for sport.
So, why don’t zebras get ulcers, as they actually are hunted for food?
They don’t have rent to pay or a mortgage, they don’t have taxes, or traffic, or a broken washing machine, or a project due in the morning. Their problems come one at a time. They have a useful stress response to a stressful situation (say, being chased by lions), and when the danger is over, they go back to grazing. They have time to recover.
For us, we are (usually) not being chased by lions. But we have everything else, constantly, around the clock. So, how to fix that?
Dr. Sapolsky comprehensively describes our physiological responses to stress in quite different terms than many. By reframing stress responses as part of the homeostatic system—trying to get the body back into balance—we find a solution, or rather: ways to help our bodies recover.
The style is “pop-science” and is very accessible for the lay reader while still clearly coming from a top-level academic who is neck-deep in neuroendocrinological research. Best of both worlds!
Bottom line: if you try to take very day at a time, but sometimes several days gang up on you at once, and you’d like to learn more about what happens inside you as a result and how to fix that, this book is for you!

Tilapia vs Cod – 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 tilapia to cod, we picked the tilapia.
Why?
Another case of “that which is more expensive is not necessarily the healthier”!
In terms of macros, tilapia has more protein and fats, as well as more omega-3 (and omega-6). On the downside, tilapia does have relatively more saturated fat, but at 0.94g/100g, it’s not exactly butter.
The vitamins category sees that tilapia has more of vitamins B1, B3, B5, B12, D, and K, while cod has more of vitamins B6, B9, and choline. A moderate win for tilapia.
When it comes to minerals, things are most divided; tilapia has more copper, iron, phosphorus, potassium, manganese, and selenium, while cod has more magnesium and zinc. An easy win for tilapia.
One other thing to note is that both of these fish contain mercury these days (and it’s worth noting: cod has nearly 10x more mercury). Mercury is, of course, not exactly a health food.
So, excessive consumption of either is not recommended, but out of the two, tilapia is definitely the one to pick.

Is it OK if my child eats lots of fruit but no vegetables?
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.
Does it seem like most vegetables you serve your children end up left on the plate, or worse, strewn across the floor? But mention dessert, and your fruit skewers are polished off in an instant.
Or maybe the carrot and cucumber sticks keep coming home in your child’s lunchbox untouched, yet the orange slices are nowhere to be seen.
If you’re facing these struggles with your child, you’re not alone. Many children prefer fruit to vegetables.
So if your child eats lots of fruit but minimal or no vegetables, is that OK? And how can you get them to eat more veggies?
Children have an innate preference for fruit
The Australian Dietary Guidelines’ recommended daily intakes for vegetables and fruit depend on a child’s age.
Fruit and vegetable serving sizes by age. The Conversation.
National Health and Medical Research Council, CC BY-SAConsumption among Australian children falls well below recommendations. Around 62.6% of children aged over two meet the recommended daily fruit intake, but only 9% meet the recommended vegetable intake.
This is not surprising given children have a natural preference for fruit. At least in part, this is due to its sweetness and texture, whether crispy, crunchy or juicy. The texture of fruit has been linked to a positive sensory experience among children.
Vegetables, on the other hand, are more of an acquired taste, and certain types, such as cruciferous vegetables, can be perceived by children as bitter.
The reason children often prefer fruit over vegetables could also be related to the parents’ preferences. Some research has even suggested we develop food preferences before birth based on what our mother consumes during pregnancy.
Balance is key
So, a preference for fruit is common. But is it OK if your child eats lots of fruit but little to no vegetables? This is a question we, as dietitians, get asked regularly.
You might be thinking, at least my child is eating fruit. They could be eating no veggies and no fruit. This is true. But while it’s great your child loves fruit, vegetables are just as important as part of a balanced eating pattern.
Vegetables provide us with energy, essential vitamins and minerals, as well as water and fibre, which help keep our bowels regular. They also support a strong immune system.
If your child is only eating fruit, they are missing some essential nutrients. But the same is true if they are eating only veggies.
Fruit likewise provides the body with a variety of essential vitamins and minerals, as well as phytochemicals, which can help reduce inflammation.
Evidence shows healthy consumption of fruit and vegetables protects against chronic diseases including high blood pressure, heart disease and stroke.
Consumed together, fruit and vegetables in a variety of colours provide different nutrients we need, some of which we can’t get from other foods. We should encourage kids to eat a “rainbow” of fruit and vegetables each day to support their growth and development.
What if my child eats too much fruit?
If your child is eating slightly more fruit than what’s recommended each day, it’s not usually a problem.
Fruit contains natural sugar which is good for you. But too much of a good thing, even if it’s natural, can create problems. Fruit also contains virtually no fat and very little to no protein, both essential for a growing child.
When overindulging in fruit starts to displace other food groups such as vegetables, dairy products and meat, that’s when things can get tricky.
6 tips to get your kids to love vegetables
1. Get them involved
Take your child with you when you go shopping. Let them choose new vegetables. See if you can find vegetables even you haven’t tried, so you’re both having a new experience. Then ask them to help you with preparing or cooking the vegetables using a recipe you have chosen together. This will expose your child to veggies in a positive way and encourage them to eat more.
2. Sensory learning
Try to expose your child to vegetables rather than hiding them. Kids are more likely to eat veggies when they see, smell and feel them. This is called sensory learning.
3. Have fun with food
Use colourful vegetables of different sizes and textures. Make them fun by creating scenes or faces on your child’s plate. Add edible flowers or mint for decoration. You can even serve this with a side of veggie-based dip such as hummus or guacamole for some bonus healthy fats.
4. Teach them to grow their own
Teach your child how to grow their own vegetables. Evidence shows kids are more inclined to try the food they have helped and watched grow. You don’t need to have a big backyard to do this. A windowsill with a pot plant is a perfect start.
5. Lead by example
Your child learns from you, and your eating habits will influence theirs. Ensure they see you eating and enjoying veggies, whether in meals or as snacks.
6. Practise persistence
If your child refuses a particular vegetable once, don’t give up. It can take many attempts to encourage children to try a new food.

How Healthy People Regulate Their Emotions
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.
Some people seem quite unflappable, while others are consistently on the edge of a breakdown or outburst. So, how does a person regulate emotions, without suppressing them?
Eight things mentally healthy people do
Doing these things is hardest when one is actually in a disrupted emotional state, so they are all good things to get in the habit of doing at all times:
- Recognize and label emotions: identify specific emotions like anxiety, excitement, frustration, and so forth. You can track them for better emotional management, but it suffices even to recognize in the moment such things as “ok, I’m feeling anxious” etc.
- Embrace self-awareness: acknowledge emotions without judgment, using mindfulness and meditation to enhance emotional awareness and reduce reactivity—view your emotions neutrally, with a detached curiosity.
- Reframe negative thoughts: use cognitive reappraisal to change your perspective on situations, viewing setbacks as opportunities for growth.
- Express emotions constructively: use outlets like writing, or talking to someone to process emotions, preventing emotional build-up. Creating expressive art can also help many.
- Seek social support: cultivate strong relationships that provide emotional support and perspective, helping to manage stress and emotions.
- Maintain physical health: exercise, sleep, and a balanced diet support emotional resilience by improving overall well-being and brain function. It’s harder to be in the best mental health if your body is collapsing from exhaustion.
- Use stress management techniques: practice deep breathing, meditation, or other (non-chemical) relaxation methods to reduce stress and calm the mind and body.
- Seek professional help when needed: when emotions become overwhelming, consider therapy to develop personalized coping mechanisms and emotional regulation strategies.
