Salt’s Health Risks… More Than Just Heart Disease!
It’s been well-established for a long time that too much salt is bad for cardiovascular health. It can lead to high blood pressure, which in turn can lead to many problems, including heart attacks.
A team of researchers has found that in addition to this, it may be damaging your organs themselves.
This is because high salt levels peel away the surfaces of blood vessels. How does this harm your organs? Because it’s through those walls that nutrients are selectively passed to where they need to be—mostly your organs. So, too much salt can indirectly starve your organs of the nutrients they need to survive. And you absolutely do not want your organs to fail!
❝We’ve identified new biomarkers for diagnosing blood vessel damage, identifying patients at risk of heart attack and stroke, and developing new drug targets for therapy for a range of blood vessel diseases, including heart, kidney and lung diseases as well as dementia❞

Diets high in salt are a huge problem in Canada, North America as a whole, and around the world. According to a World Health Organization (WHO) report released March 9, Canadians consume 9.1 grams of salt per day.

You may be wondering: who is eating over 9g of salt per day?
And the answer is: mostly, people who don’t notice how much salt is already in processed foods… don’t see it, and don’t think about it.
Meanwhile, the WHO recommends the average person to consume no more than five grams, or one teaspoon, of salt per day.

The American Heart Association, tasked with improving public health with respect to the #1 killer of Americans (it’s also the #1 killer worldwide—but that’s not the AHA’s problem), goes further! It recommends no more than 2.3g per day, and ideally, no more than 1.5g per day.
Some handy rules-of-thumb
Here are sodium-related terms you may see on food packages:
- Salt/Sodium-Free = Less than 5mg of sodium per serving
- Very Low Sodium = 35mg or less per serving
- Low Sodium = 140mg or less per serving
- Reduced Sodium = At least 25% less sodium per serving than the usual sodium level
- Light in Sodium or Lightly Salted = At least 50% less sodium than the regular product
Confused by milligrams? Instead of remembering how many places to move the decimal point (and potentially getting an “out by an order of magnitude error—we’ve all been there!), think of the 1.5g total allowance as being 1500mg.

Based heavily in hard science, with more than 450 citations in over 300 pages, the exhortation is not just “trust me, lol”.
Instead, she encourages the reader to experiment. Not like “try this and see if it works”, but “here’s how to try this, using scientific method with good controls and good record-keeping”.
The book is divided into sections, each with a projection of time required at the start and a summary at the end. The reading style is easy-reading throughout, without sacrificing substance.
It proposes seven key interventions. If just one works for you, it’ll be worth having bought and read the book. More likely most if not all will… Because that’s how science works.

New study suggests weight loss drugs like Ozempic could help with knee pain. Here’s why there may be a link
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 drug semaglutide, commonly known by the brand names Ozempic or Wegovy, was originally developed to help people with type 2 diabetes manage their blood sugar levels.
However, researchers have discovered it may help with other health issues, too. Clinical trials show semaglutide can be effective for weight loss, and hundreds of thousands of people around the world are using it for this purpose.
Evidence has also shown the drug can help manage heart failure and chronic kidney disease in people with obesity and type 2 diabetes.
Now, a study published in the New England Journal of Medicine has suggested semaglutide can improve knee pain in people with obesity and osteoarthritis. So what did this study find, and how could semaglutide and osteoarthritis pain be linked?
Osteoarthritis and obesity
Osteoarthritis is a common joint disease, affecting 2.1 million Australians. Most people with osteoarthritis have pain and find it difficult to perform common daily activities such as walking. The knee is the joint most commonly affected by osteoarthritis.
Being overweight or obese is a major risk factor for osteoarthritis in the knee. The link between the two conditions is complex. It involves a combination of increased load on the knee, metabolic factors such as high cholesterol and high blood sugar, and inflammation.
For example, elevated blood sugar levels increase the production of inflammatory molecules in the body, which can damage the cartilage in the knee, and lead to the development of osteoarthritis.
Weight loss is strongly recommended to reduce the pain of knee osteoarthritis in people who are overweight or obese. International and Australian guidelines suggest losing as little as 5% of body weight can help.
But losing weight with just diet and exercise can be difficult for many people. One study from the United Kingdom found the annual probability of people with obesity losing 5% or more of their body weight was less than one in ten.
Semaglutide has recently entered the market as a potential alternative route to weight loss. It comes from a class of drugs known as GLP-1 receptor agonists and works by increasing a person’s sense of fullness.
Semaglutide for osteoarthritis?
The rationale for the recent study was that while we know weight loss alleviates symptoms of knee osteoarthritis, the effect of GLP-1 receptor agonists was yet to be explored. So the researchers set out to understand what effect semaglutide might have on knee osteoarthritis pain, alongside body weight.
They randomly allocated 407 people with obesity and moderate osteoarthritis into one of two groups. One group received semaglutide once a week, while the other group received a placebo. Both groups were treated for 68 weeks and received counselling on diet and physical activity. At the end of the treatment phase, researchers measured changes in knee pain, function, and body weight.
As expected, those taking semaglutide lost more weight than those in the placebo group. People on semaglutide lost around 13% of their body weight on average, while those taking the placebo lost around 3% on average. More than 70% of people in the semaglutide group lost at least 10% of their body weight compared to just over 9% of people in the placebo group.
The study found semaglutide reduced knee pain significantly more than the placebo. Participants who took semaglutide reported an additional 14-point reduction in pain on a 0–100 scale compared to the placebo group.
This is much greater than the pain reduction in another recent study among people with obesity and knee osteoarthritis. This study investigated the effects of a diet and exercise program compared to an attention control (where participants are provided with information about nutrition and physical activity). The results here saw only a 3-point difference between the intervention group and the control group on the same scale.
The amount of pain relief reported in the semaglutide trial is also larger than that reported with commonly used pain medicines such as anti-inflammatories, opioids and antidepressants.
Semaglutide also improved knee function compared to the placebo. For example, people who took semaglutide could walk about 42 meters further than those on the placebo in a six-minute walking test.
How could semaglutide reduce knee pain?
It’s not fully clear how semaglutide helps with knee pain from osteoarthritis. One explanation may be that when a person loses weight, there’s less stress on the joints, which reduces pain.
But recent studies have also suggested semaglutide and other GLP-1 receptor agonists might have anti-inflammatory properties, and could even protect against cartilage wear and tear.
While the results of this new study are promising, it’s too soon to regard semaglutide as a “miracle drug” for knee osteoarthritis. And as this study was funded by the drug company that makes semaglutide, it will be important to have independent studies in the future, to confirm the findings, or not.
The study also had strict criteria, excluding some groups, such as those taking opioids for knee pain. One in seven Australians seeing a GP for their knee osteoarthritis are prescribed opioids. Most participants in the trial were white (61%) and women (82%). This means the study may not fully represent the average person with knee osteoarthritis and obesity.
It’s also important to consider semaglutide can have a range of side effects, including gastrointestinal symptoms and fatigue.
There are some concerns that semaglutide could reduce muscle mass and bone density, though we’re still learning more about this.
Further, it can be difficult to access.
I have knee osteoarthritis, what should I do?
Osteoarthritis is a disease caused by multiple factors, and it’s important to take a multifaceted approach to managing it. Weight loss is an important component for those who are overweight or obese, but so are other aspects of self-management. This might include physical activity, pacing strategies, and other positive lifestyle changes such as improving sleep, healthy eating, and so on.

Carrots vs Parsnips – 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 carrots to parsnips, we picked the parsnips.
Why?
There are arguments for both! But we say parsnips win on overall nutritional density.
In terms of macros, parsnips vary quite a lot from region to another, but broadly speaking, parsnips have more carbs and fiber, and/but the ratios are such that carrots have the lower glycemic index. We’ll call this one a win for carrots.
When it comes to vitamins, carrots have more of vitamins A, B2, B3, B6, and choline, while parsnips have more of vitamins B1, B5, B9, C, E, and K. A small win for parsnips here.
In the category of minerals, carrots are not higher in any minerals, while parsnips are higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. An overwhelming win for parsnips.
While the overall vitamin and mineral content puts parsnips ahead, it’s still worth noting that carrots have highly bioavailable megadoses of vitamin A.
Another thing to note is that the glycemic index recorded for both is when peeled and boiled, whereas both of these root vegetables can be enjoyed raw if you wish, which has a much lower GI.
In short, enjoy either or both, but parsnips are the more nutritionally dense overall.

America’s Health System Isn’t Ready for the Surge of Seniors With Disabilities
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 number of older adults with disabilities — difficulty with walking, seeing, hearing, memory, cognition, or performing daily tasks such as bathing or using the bathroom — will soar in the decades ahead, as baby boomers enter their 70s, 80s, and 90s.
But the health care system isn’t ready to address their needs.
That became painfully obvious during the covid-19 pandemic, when older adults with disabilities had trouble getting treatments and hundreds of thousands died. Now, the Department of Health and Human Services and the National Institutes of Health are targeting some failures that led to those problems.
One initiative strengthens access to medical treatments, equipment, and web-based programs for people with disabilities. The other recognizes that people with disabilities, including older adults, are a separate population with special health concerns that need more research and attention.
Lisa Iezzoni, 69, a professor at Harvard Medical School who has lived with multiple sclerosis since her early 20s and is widely considered the godmother of research on disability, called the developments “an important attempt to make health care more equitable for people with disabilities.”
“For too long, medical providers have failed to address change in society, changes in technology, and changes in the kind of assistance that people need,” she said.
Among Iezzoni’s notable findings published in recent years:
Most doctors are biased. In survey results published in 2021, 82% of physicians admitted they believed people with significant disabilities have a worse quality of life than those without impairments. Only 57% said they welcomed disabled patients.
“It’s shocking that so many physicians say they don’t want to care for these patients,” said Eric Campbell, a co-author of the study and professor of medicine at the University of Colorado.
While the findings apply to disabled people of all ages, a larger proportion of older adults live with disabilities than younger age groups. About one-third of people 65 and older — nearly 19 million seniors — have a disability, according to the Institute on Disability at the University of New Hampshire.
Doctors don’t understand their responsibilities. In 2022, Iezzoni, Campbell, and colleagues reported that 36% of physicians had little to no knowledge of their responsibilities under the 1990 Americans With Disabilities Act, indicating a concerning lack of training. The ADA requires medical practices to provide equal access to people with disabilities and accommodate disability-related needs.
Among the practical consequences: Few clinics have height-adjustable tables or mechanical lifts that enable people who are frail or use wheelchairs to receive thorough medical examinations. Only a small number have scales to weigh patients in wheelchairs. And most diagnostic imaging equipment can’t be used by people with serious mobility limitations.
Iezzoni has experienced these issues directly. She relies on a wheelchair and can’t transfer to a fixed-height exam table. She told me she hasn’t been weighed in years.
Among the medical consequences: People with disabilities receive less preventive care and suffer from poorer health than other people, as well as more coexisting medical conditions. Physicians too often rely on incomplete information in making recommendations. There are more barriers to treatment and patients are less satisfied with the care they do get.
Egregiously, during the pandemic, when crisis standards of care were developed, people with disabilities and older adults were deemed low priorities. These standards were meant to ration care, when necessary, given shortages of respirators and other potentially lifesaving interventions.
There’s no starker example of the deleterious confluence of bias against seniors and people with disabilities. Unfortunately, older adults with disabilities routinely encounter these twinned types of discrimination when seeking medical care.
Such discrimination would be explicitly banned under a rule proposed by HHS in September. For the first time in 50 years, it would update Section 504 of the Rehabilitation Act of 1973, a landmark statute that helped establish civil rights for people with disabilities.
The new rule sets specific, enforceable standards for accessible equipment, including exam tables, scales, and diagnostic equipment. And it requires that electronic medical records, medical apps, and websites be made usable for people with various impairments and prohibits treatment policies based on stereotypes about people with disabilities, such as covid-era crisis standards of care.
“This will make a really big difference to disabled people of all ages, especially older adults,” said Alison Barkoff, who heads the HHS Administration for Community Living. She expects the rule to be finalized this year, with provisions related to medical equipment going into effect in 2026. Medical providers will bear extra costs associated with compliance.
Also in September, NIH designated people with disabilities as a population with health disparities that deserves further attention. This makes a new funding stream available and “should spur data collection that allows us to look with greater precision at the barriers and structural issues that have held people with disabilities back,” said Bonnielin Swenor, director of the Johns Hopkins University Disability Health Research Center.
One important barrier for older adults: Unlike younger adults with disabilities, many seniors with impairments don’t identify themselves as disabled.
“Before my mom died in October 2019, she became blind from macular degeneration and deaf from hereditary hearing loss. But she would never say she was disabled,” Iezzoni said.
Similarly, older adults who can’t walk after a stroke or because of severe osteoarthritis generally think of themselves as having a medical condition, not a disability.
Meanwhile, seniors haven’t been well integrated into the disability rights movement, which has been led by young and middle-aged adults. They typically don’t join disability-oriented communities that offer support from people with similar experiences. And they don’t ask for accommodations they might be entitled to under the ADA or the 1973 Rehabilitation Act.
Many seniors don’t even realize they have rights under these laws, Swenor said. “We need to think more inclusively about people with disabilities and ensure that older adults are fully included at this really important moment of change.”

How To Nap Like A Pro (No More “Sleep Hangovers”!)
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.
How To Be An Expert Nap-Artist
There’s a lot of science to say that napping can bring us health benefits—but mistiming it can just make us more tired. So, how to get some refreshing shut-eye, without ending up with a case of the midday melatonin blues?
First, why do we want to nap?
Well, maybe we’re just tired, but there are specific benefits even if we’re not. For example:
- Increased alertness
- Helps with learning
- Improved memory
- Boost to immunity
- Enhance athletic performance
What can go wrong?
There are two main things that can go wrong, physiologically speaking:
- We can overdo it, and not sleep well at night
- We can awake groggy and confused and tired
The first is self-explanatory—it messes with the circadian rhythm. For this reason, we should not sleep more than 90 minutes during the day. If that seems like a lot, and maybe you’ve heard that we shouldn’t sleep more than half an hour, there is science here, so read on…
The second is a matter of sleep cycles. Our brain naturally organizes our sleep into multiples of 20-minute segments, with a slight break of a few minutes between each. Consequently, naps should be:
- 25ish minutes
- 40–45 minutes
- 90ish minutes
If you wake up mid-cycle—for example, because your alarm went off, or someone disturbed you, or even because you needed to pee, you will be groggy, disoriented, and exhausted.
For this reason, a nap of one hour (a common choice, since people like “round” numbers) is a recipe for disaster, and will only work if you take 15 minutes to fall asleep. In which case, it’d really be a nap of 45 minutes, made up of two 20-minute sleep cycles.
Some interruptions are better/worse than others
If you’re in light or REM sleep, a disruption will leave you not very refreshed, but not wiped out either. And as a bonus, if you’re interrupted during a REM cycle, you’re more likely to remember your dreams.
If you’re in deep sleep, a disruption will leave you with what feels like an incredible hangover, minus the headache, and you’ll be far more tired than you were before you started the nap.
The best way to nap
Taking these factors into account, one of the “safest” ways to nap is to set your alarm for the top end of the time-bracket above the one you actually want to nap for (e.g., if you want to nap for 25ish minutes, set your alarm for 45).
Unless you’re very sleep-deprived, you’ll probably wake up briefly after 20–25 minutes of sleep. This may seem like nearer 30 minutes, if it took you some minutes to fall asleep!
If you don’t wake up then, or otherwise fail to get up, your alarm will catch you later at what will hopefully be between your next sleep cycles, or at the very least not right in the middle of one.
When you wake up from a nap before your alarm, get up. This is not the time for “5 more minutes” because “5 more minutes” will never, ever, be refreshing.
Rest well!

What Happens To Your Body When You Eat Raw Garlic Everyday
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.
Garlic’s benefits are not all in its most talked-about active compound, allicin (some are in other parts of the garlic), but the allicin is certainly very potent. However, allicin breaks down easily, which means that cooking reduces its value greatly, meaning that for health purposes, it is best consumed raw. Pickled garlic cloves are great, by the way, and you should try them if you haven’t already.
Garlic’s benefits (aside from being delicious)
Benefits that can be expected include:
- Boosts immunity: allicin enhances white blood cell function, helping fight off colds and flu
- Supports heart health: lowers blood pressure, reduces cholesterol, and prevents blood clots, reducing the risk of heart disease and stroke
- Anti-cancer properties: it contains sulfur compounds that may inhibit cancer cell growth, particularly in the digestive system
- Improves digestion: stimulates digestive enzymes and promotes gut health, helping with better nutrient absorption and digestion
- Enhances brain function: antioxidants in garlic are neuroprotective, reducing cognitive decline
- Good for your skin: its antibacterial and anti-inflammatory properties can help improve skin health
- Regulates blood sugar levels: helps regulate blood sugar and improves insulin sensitivity
- Anti-inflammatory effects: contains compounds that reduce inflammation, helping to combat inflammatory diseases such as arthritis
- Supports weight loss: stimulates metabolism, suppresses appetite, and helps break down fats, aiding in weight management
- May protect against osteoporosis: increases estrogen levels in women, potentially reducing the risk of osteoporosis (no effect on estrogen levels if you don’t have ovaries)
The daily dose that this video recommends is 1–2 cloves of garlic or 3600mg of aged garlic extract as a supplement.
