Our Verdict
When comparing avocado to blueberries, we picked the avocado.
Why?
These two fruits aren’t as similar as some of the comparisons we’ve made—we often go for “can be used in the same way culinarily” comparisons. But! They are both popularly in the “superfood” category, so it’s interesting to consider:
In terms of macros, avocado has more protein, (healthy!) fat, and fiber, while blueberries have more carbs. An easy win for avocado here, unless you’re on a calorie-controlled diet perhaps, since avocado is also higher in those. About that fat; it’s mostly monounsaturated, with some polyunsaturated and saturated, and is famously a good source of omega-3 in the form of ALA.
In the category of vitamins, avocado has more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, E, K, and choline, while blueberries are not higher in any vitamins. So, not a tricky decision here.
When it comes to minerals, avocado has more calcium, copper, iron, magnesium, phosphorus, potassium, selenium, and zinc, while blueberries are higher in manganese. Another win for avocados.
There is one other category that’s important to consider in this case, and that’s polyphenols. We’d be here all day if we listed them all, but in total, blueberries have about 1193x the polyphenol content that avocados do. Blueberries got the reputation for antioxidant properties for a reason; it is well-deserved!
So, out of the two, we declare avocado the overall more nutritious of the two, but blueberries absolutely deserve the acclaim they get also.

Avoiding/Managing Osteoarthritis
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 Osteoarthritis
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).
Inflammatory vs Non-Inflammatory Arthritis
Arthritis is broadly divided into inflammatory arthritis and non-inflammatory arthritis.
Some forms, such as rheumatoid arthritis, are of the inflammatory kind. We wrote about that previously:
See: Avoiding/Managing Rheumatoid 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; it’s just not the prime focus.
So, what should we focus on?
First and foremost: avoiding wear-and-tear if possible. Naturally, we all must live our lives, and sometimes that means taking a few knocks, and definitely it means using our joints. An unused joint would suffer just as much as an abused one. But, we can take care of our joints!
We wrote on that previously, too:
See: How To Really Look After Your Joints
New osteoarthritis medication (hot off the press!)
At 10almonds, we try to keep on top of new developments, and here’s a shiny new one from this month:
- Methotrexate to treat hand osteoarthritis with synovitis (12th Oct, clinical trial)
- New research has found an existing drug could help many people with painful hand osteoarthritis (24th Oct, pop-science article about the above, but still written by one of the study authors!)
Note also that Dr. Flavia Cicuttini there talks about what we talked about above—that calling it non-inflammatory arthritis is a little misleading, as the inflammation still occurs.
And finally…
You might consider other lifestyle adjustments to manage your symptoms. These include:
- Exercise—gently, though!
- Rest—while keeping mobility going.
- Mobility aids—if it helps, it helps.
- 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.

I’ve recovered from a cold but I still have a hoarse voice. What should I do?
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.
Cold, flu, COVID and RSV have been circulating across Australia this winter. Many of us have caught and recovered from one of these common upper respiratory tract infections.
But for some people their impact is ongoing. Even if your throat isn’t sore anymore, your voice may still be hoarse or croaky.
So what happens to the voice when we get a virus? And what happens after?
Here’s what you should know if your voice is still hoarse for days – or even weeks – after your other symptoms have resolved.
Why does my voice get croaky during a cold?
A healthy voice is normally clear and strong. It’s powered by the lungs, which push air past the vocal cords to make them vibrate. These vibrations are amplified in the throat and mouth, creating the voice we hear.
The vocal cords are two elastic muscles situated in your throat, around the level of your laryngeal prominence, or Adam’s apple. (Although everyone has one, it tends to be more pronounced in males.) The vocal cords are small and delicate – around the size of your fingernail. Any small change in their structure will affect how the voice sounds.
When the vocal cords become inflamed – known as laryngitis – your voice will sound different. Laryngitis is a common part of upper respiratory tract infections, but can also be caused through misuse.
Viruses such as the common cold can inflame the vocal cords. Pepermpron/Shutterstock Catching a virus triggers the body’s defence mechanisms. White blood cells are recruited to kill the virus and heal the tissues in the vocal cords. They become inflamed, but also stiffer. It’s harder for them to vibrate, so the voice comes out hoarse and croaky.
In some instances, you may find it hard to speak in a loud voice or have a reduced pitch range, meaning you can’t go as high or loud as normal. You may even “lose” your voice altogether.
Coughing can also make things worse. It is the body’s way of trying to clear the airways of irritation, including your own mucus dripping onto your throat (post-nasal drip). But coughing slams the vocal cords together with force.
Chronic coughing can lead to persistent inflammation and even thicken the vocal cords. This thickening is the body trying to protect itself, similar to developing a callus when a pair of new shoes rubs.
Thickening on your vocal cords can lead to physical changes in the vocal cords – such as developing a growth or “nodule” – and further deterioration of your voice quality.
Coughing and exertion can cause inflamed vocal cords to thicken and develop nodules. Pepermpron/Shutterstock How can you care for your voice during infection?
People who use their voices a lot professionally – such as teachers, call centre workers and singers – are often desperate to resume their vocal activities. They are more at risk of forcing their voice before it’s ready.
The good news is most viral infections resolve themselves. Your voice is usually restored within five to ten days of recovering from a cold.
Occasionally, your pharmacist or doctor may prescribe cough suppressants to limit additional damage to the vocal cords (among other reasons) or mucolytics, which break down mucus. But the most effective treatments for viral upper respiratory tract infections are hydration and rest.
Drink plenty of water, avoid alcohol and exposure to cigarette smoke. Inhaling steam by making yourself a cup of hot water will also help clear blocked noses and hydrate your vocal cords.
Rest your voice by talking as little as possible. If you do need to talk, don’t whisper – this strains the muscles.
Instead, consider using “confidential voice”. This is a soft voice – not a whisper – that gently vibrates your vocal cords but puts less strain on your voice than normal speech. Think of the voice you use when communicating with someone close by.
During the first five to ten days of your infection, it is important not to push through. Exerting the voice by talking a lot or loudly will only exacerbate the situation. Once you’ve recovered from your cold, you can speak as you would normally.
What should you do if your voice is still hoarse after recovery?
If your voice hasn’t returned to normal after two to three weeks, you should seek medical attention from your doctor, who may refer you to an ear nose and throat specialist.
If you’ve developed a nodule, the specialist would likely refer you to a speech pathologist who will show you how to take care of your voice. Many nodules can be treated with voice therapy and don’t require surgery.
You may have also developed a habit of straining your vocal cords, if you forced yourself to speak or sing while they were inflamed. This can be a reason why some people continue to have a hoarse voice even when they’ve recovered from the cold.
In those cases, a speech pathologist may play a valuable role. They may teach you to exercises that make voicing more efficient. For example, lip trills (blowing raspberries) are a fun and easy way you can learn to relax the voice. This can help break the habit of straining your voice you may have developed during infection.

Chorus or Cacophony? Cicada Song Hits Some Ears Harder Than Others
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.
ST. LOUIS — Shhhooo. Wee-uuu. Chick, chick, chick. That’s the sound of three different cicada species. For some people, those sounds are the song of the summer. Others wish the insects would turn it down. The cacophony can be especially irritating for people on the autism spectrum who have hearing sensitivity.
Warren Rickly, 14, lives in suburban south St. Louis County, Missouri. Warren, who has autism, was at the bus stop recently waiting for his younger brother when the sound of cicadas became too much to bear.
“He said it sounds like there’s always a train running next to him,” his mother, Jamie Reed, said.
Warren told her the noise hurt.
Starting this spring, trillions of the red-eyed insects crawled their way out of the ground across the Midwest and Southeast. It’s part of a rare simultaneous emergence of two broods — one that appears every 13 years, the other every 17.
The noisy insects can be stressful. People with autism can have a sensitivity to texture, brightness, and sound.
“I think the difference for individuals with autism is the level of intensity or how upsetting some of these sensory differences are,” said Rachel Follmer, a developmental and behavioral pediatrician at Lurie Children’s Hospital in Chicago.
“It can get to the extreme where it can cause physical discomfort,” she said.
When a large group of cicadas starts to sing, the chorus can be as loud as a motorcycle. Researchers at the University of Missouri-St. Louis this year crowdsourced cicada noise levels as high as 86 decibels, about as loud as a food blender.
That can be stressful, not melodic, Follmer said.
To help children cope, she suggests giving them a primer before they encounter a noisy situation. For cicadas, that could mean explaining what they are, that they don’t bite or sting, and that they’ll be here for just a short time.
“When something is uncomfortable, not having power in that situation can be very scary for a lot of individuals, whether you’re on the spectrum or not,” Follmer said.
Jamie Reed’s family has been using this and other strategies to help her son. Warren wears noise-canceling headphones, listens to music, and has been teaching himself about cicadas.
“For him, researching it and looking into it I think grounds him a little bit,” Reed said.
Fatima Husain is a professor and neuroscientist at the University of Illinois Urbana-Champaign and studies how the brain processes sound. She said people with tinnitus may also struggle with cicada song.
Tinnitus, a ringing or other noise in the ears, is a person’s perception of sound without an external source.
“Some people say it sounds like buzzing, like wind blowing through trees, and ironically, quite a few people say it sounds like cicadas,” Husain said.
For most people with tinnitus the cicada’s song is harmless background noise, according to Husain, but for others the ringing can prevent easy conversation or sleep. Those with tinnitus are also more likely to have anxiety or depression. A loud persistent sound, like singing cicadas, can make someone’s tinnitus worse, Husain said.
It’s not always bad, though. The cicada’s song can also be a relief.
For some, tinnitus gets worse in a quiet environment. Husain said she’s seen reports this year of patients saying the cicadas’ song has been like soothing white noise.
“The sound is loud enough that in some ways it’s drowning their internal tinnitus,” Husain said.
As loud as the cicadas can be, they won’t necessarily damage anyone’s hearing, according to the Centers for Disease Control and Prevention. Hearing loss builds up over time from repeated exposure to loud sounds. Cicadas aren’t loud enough for long enough to do lasting damage, Husain said.
Everyday sources of noise come with a higher risk. Husain said constant exposure to loud highways, an airport, industrial sites, or household appliances like blenders and hair dryers can be a concern. And they can take a toll on someone’s emotional well-being.
“If you are being exposed to very loud sounds for a part of your school day or your working day, it may make you more stressed out; it may make you more angry about things,” she said.
Unlike the highway or an airport, cicadas won’t be around long. Most of the current brood will be gone in the next few weeks. Just in time for another noisy summer event: the Fourth of July.

The End of Food Allergy – by Dr. Kari Nadeau & Sloan Barnett
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 don’t usually mention author credentials beyond their occupation/title. However, in this case it bears acknowledging at least the first line of the author bio:
❝Kari Nadeau, MD, PhD, is the director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford University and is one of the world’s leading experts on food allergy❞
We mention this, because there’s a lot of quack medicine out there [in general, but especially] when it comes to things such as food allergies. So let’s be clear up front that Dr. Nadeau is actually a world-class professional at the top of her field.
This book is, by the way, about true allergies—not intolerances or sensitivities. It does touch on those latter two, but it’s not the main meat of the book.
In particular, most of the research cited is around peanut allergies, though the usual other common allergens are all discussed too.
The authors’ writing style is that of a science educator (Dr. Nadeau’s co-author, Sloan Barnett, is lawyer and health journalist). We get a clear explanation of the science from real-world to clinic and back again, and are left with a strong understanding, not just a conclusion.
The titular “End of Food Allergy” is a bold implicit claim; does the book deliver? Yes, actually.
The book lays out guidelines for safely avoiding food allergies developing in infants, and yes, really, how to reverse them in adults. But…
Big caveat:
The solution for reversing severe food allergies (e.g. “someone nearby touched a peanut three hours ago and now I’m in anaphylactic shock”), drug-assisted oral immunotherapy, takes 6–24 months of weekly several-hour-long clinic visits, relies on having a nearby clinic offering the service, and absolutely 100% cannot be done at home (on pain of probable death).
Bottom line: it’s by no means a magic bullet, but yes, it does deliver.

Holding Back The Clock on Aging
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.
Holding Back The Clock on Aging
This is Dr. Eric Verdin, President and CEO of the Buck Institute of Research on Aging. He’s also held faculty positions at the University of Brussels, the NIH, and the Picower Institute for Medical Research. Dr. Verdin is also a professor of medicine at University of California, San Francisco.
Dr. Verdin’s laboratory focuses on the role of epigenetic regulators (especially the behaviors of certain enzymes) in the aging process. He studies how metabolism, diet, and chemical factors regulate the aging process and its associated diseases, including Alzheimer’s.
He has published more than 210 scientific papers and holds more than 15 patents. He is a highly cited scientist and has been recognized for his research with a Glenn Award for Research in Biological Mechanisms of Aging.
And that’s just what we could fit here! Basically, he knows his stuff.
What we can do
Dr. Verdin’s position is bold, but rooted in evidence:
❝Lifestyle is responsible for about 93% of our longevity—only about 7% is genetics. Based on the data, if implementing health lifestyle choices, most people could live to 95 in good health. So there’s 15 to 17 extra years of healthy life that is up for grabs❞
~ Dr. Eric Verdin
See for example:
- From discoveries in aging research to therapeutics for healthy aging
- Optimism, lifestyle, and longevity in a racially diverse cohort of women
- Well-being, food habits, and lifestyle for longevity—evidence from supercentenarians
How we can do it
Well, we all know “the big five”:
- Good diet (Mediterranean Diet as usual is recommended)
- Good exercise (more on this in a moment)
- Good sleep (more on this in a moment)
- Avoid alcohol (not controversial)
- Don’t smoke (need we say more)
When it comes to exercise, generally recognized as good is at least 150 minutes per week of moderate intensity exercise (for example, a brisk walk, or doing the gardening), and at least three small sessions a week of high intensity exercise, unless contraindicated by some medical condition.
As for Dr. Verdin’s take on this…
What Dr. Verdin recommends is:
- make it personalized
- make it pre-emptive
- make it better
The perfect exercise plan is only perfect if you actually do it. And if you actually can do it, for that matter.
Prevention is so much better (and easier) than cure for a whole array of maladies. So while there may be merit in thinking “what needs fixing”, Dr. Verdin encourages us to take extra care to not neglect factors of our health that seem “good enough”. Because, give them time and neglect, and they won’t be!
Wherever we’re at in life and health, there’s always at least some little way we could make it a bit better. Dr. Verdin advises us to seek out those little improvements, even if it’s just a nudge better here, a nudge better there, all those nudges add up!
About sleep…
It’s perhaps the easiest one to neglect (writer’s note: as a writer, I certainly feel that way!), but his biggest take-away tip for this is:
Worry less about what time you set an alarm for in the morning. Instead, set an alarm for the evening—to remind you when to go to bed.
Want to hear directly from the man himself?
Here he is speaking on progress we can expect for the next decade in the field of aging research, as part of the 100 Minutes of Longevity session at The Longevity Forum, a few months ago:
