Spinach vs Kale – Which is Healthier?

Our Verdict
When comparing spinach to kale, we picked the spinach.
Why?
In terms of macros, spinach and kale are very similar. They are mostly water wrapped in fiber, with very small amounts of carbohydrates and protein and trace amounts of fat.
Spinach has a lot more vitamins and minerals—a wider variety, and in most cases, more of them.
Kale is notably higher in vitamin C, though. Everything else, spinach is higher or close to equal.
Spinach is especially notably a lot higher in B vitamins, as well as iron, calcium, magnesium, and zinc.
One downside to spinach, though, which is that it’s high in oxalates, which can increase the risk of kidney stones. If your kidneys are in good health and you eat spinach in moderation, this is not a problem for most people—but if your kidneys aren’t in good health (or you are, for whatever reason, consuming Popeye levels of spinach), you might consider switching to kale.
While spinach swept the board in most categories, kale remains a very good option too, and a diet diverse in many kinds of plants is usually best.

Tasty Hot-Or-Cold Soup
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.
Full of fiber as well as vitamins and minerals, this versatile “serve it hot or cold” soup is great whatever the weather—give it a try!
You will need
- 1 quart low-sodium vegetable stock—ideally you made this yourself from vegetable offcuts you kept in the freezer until you had enough to boil in a big pan, but failing that, a large supermarket will generally be able to sell you low-sodium stock cubes.
- 2 medium potatoes, peeled and diced
- 2 leeks, chopped
- 2 stalks celery, chopped
- 1 large onion, diced
- 1 large carrot, diced, or equivalent small carrots, sliced
- 1 zucchini, diced
- 1 red bell pepper, diced
- 1 tsp rosemary
- 1 tsp thyme
- ¼ bulb garlic, minced
- 1 small piece (equivalent of a teaspoon) ginger, minced
- 1 tsp red chili flakes
- 1 tsp black pepper, coarse ground
- ½ tsp turmeric
- Extra virgin olive oil, for frying
- Optional: ½ tsp MSG or 1 tsp low-sodium salt
About the MSG/salt: there should be enough sodium already from the stock and potatoes, but in case there’s not (since not all stock and potatoes are made equal), you might want to keep this on standby.
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a sauté pan, and add the diced onion, frying until it begins to soften.
2) Add the ginger, potato, carrot, and leek, and stir for about 5 minutes. The hard vegetables won’t be fully cooked yet; that’s fine.
3) Add the zucchini, red pepper, celery, and garlic, and stir for another 2–3 minutes.
4) Add the remaining ingredients; seasonings first, then vegetable stock, and let it simmer for about 15 minutes.
5) Check the potatoes are fully softened, and if they are, it’s ready to serve if you want it hot. Alternatively, let it cool, chill it in the fridge, and enjoy it cold:

Brave – by Dr. Margie Warrell
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.
Whether it’s the courage to jump out of a plane or the courage to have a difficult conversation, bravery is an important quality that we often don’t go far out of our way to grow. At least, not as adults.
Rather than viewing bravery as a static attribute—you either have it or you don’t—psychologist Dr. Margie Warrell makes the case for its potential for lifelong development.
The book is divided into five sections:
- Live purposefully
- Speak bravely
- Work passionately
- Dig deep
- Dare boldly
…and each has approximately 10 chapters, each a few pages long, the kind that can easily make this a “chapter-a-day” daily reader.
As a quick clarification: that “speak bravely” section isn’t about public speaking, but is rather about speaking up when it counts. Life is too short for regrets, and our interactions with others tend to be what matters most in the long-run. It makes a huge difference to our life!
Dr. Warrell gives us tools to reframe our challenges and tackle them. Rather than just saying “Feel the fear and do it anyway”, she also delivers the how, in all aspects. This is one of the main values the book brings, as well as a sometimes-needed reminder of how and why being brave is something to which we should always aspire… and hold.
Bottom line: if you’d like to be more brave—in any context—this book can help. We only get one life; might as well live it.

Edamame vs Natto – 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 edamame to nattō, we picked the nattō.
Why?
Yes, they are both soy beans, but in the battle of young and green vs old and fermented, there are some important differences:
In terms of macros, nattō has nearly 2x the protein for only slightly more carbs, and slightly more fiber, as well as more fat, but it’s not much and it’s a healthy profile, mostly polyunsaturated. All in all, a win for nattō in the macros category.
In the category of vitamins, edamame has more of vitamins B1, B5, B9, E, and K, while nattō has more of vitamins B2, B6, and C, this a 5:3 win for edamame in this round.
When it comes to minerals, edamame is not higher in any minerals, while nattō has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. An overwhelming win for nattō.
A word on phytoestrogens: soy in general contains these, including both of these iterations of soy, and/but the human body can’t use plant estrogens as such. What it can do, however, is break them down and use the bits to make human estradiol, if and only if you have ovaries that are present and operational (so, no menopause and/or bilateral ovariectomy). Either way, there’s nothing to set one ahead of the other in this matter in this head-to-head.
As an extra point in nattō’s favor, nattō is, like many fermented foods, extra-good for gut health by bringing a wealth of beneficial bacteria. Edamame is also good for gut health (just by virtue of being an edible plant and containing fiber), but not on the same level as nattō.
Adding up the sections makes a clear win for nattō, but by all means enjoy either or both—diversity is good!

Ginkgo Biloba, For Memory And, Uh, What Else Again?
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.
Ginkgo biloba, for memory and, uh, what else again?
Ginkgo biloba extract has enjoyed use for thousands of years for an assortment of uses, and has made its way from Traditional Chinese Medicine, to the world supplement market at large. See:
Ginkgo biloba: A Treasure of Functional Phytochemicals with Multimedicinal Applications
But what does the science say about the specific claims?
Antioxidant & anti-inflammatory
We’re going to lump these two qualities together for examination, since one invariably leads to the other.
A quick note: things that have antioxidant and anti-inflammatory properties, often also help guard against cancer and aging. However, in this case, there are few good studies pertaining to anti-aging, and none that we could find pertaining to anti-cancer potential.
So, does it have antioxidant and anti-inflammatory properties, first?
Yes, it has potent antioxidants that do fight inflammation; this is clear, from an abundance of in vitro and in vivo studies, including with human patients:
- Properties of Ginkgo biloba L.: incl. Antioxidant Characterization
- Anti-inflammatory effects of Ginkgo biloba extract against hippocampal neuronal injury
- Gingko biloba-derived lactone prevents osteoarthritis by activating anti-inflammatory signaling pathway
- The anti-inflammatory properties of Ginkgo biloba for the treatment of pulmonary diseases
In short: it helps, and there’s plenty of science for it.
What about anti-aging effects?
For this, there is science, but a lot of the science is not great. As one team of researchers concluded while doing a research review of their own:
❝Based on the reviewed information regarding EGb’s effects in vitro and in vivo, most have reported very positive outcomes with strong statistical analyses, indicating that EGb must have some sort of beneficial effect.
However, information from the reported clinical trials involving EGb are hardly conclusive since many do not include information such as the participant’s age and physical condition, drug doses administered, duration of drug administered as well as suitable control groups for comparison.
We therefore call on clinicians and clinician-scientists to establish a set of standard and reliable standard operating procedure for future clinical studies to properly evaluate EGb’s effects in the healthy and diseased person since it is highly possible it possesses beneficial effects.❞
Translation from sciencese: “These results are great, but come on, please, we are begging you to use more robust methodology”
If you’d like to read the review in question, here it is:
Advances in the Studies of Ginkgo Biloba Leaves Extract on Aging-Related Diseases
Does it have cognitive enhancement effects?
The claims here are generally that it helps:
- improve memory
- improve focus
- reduce cognitive decline
- reduce anxiety and depression
Let’s break these down:
Does it improve memory and cognition?
Ginkgo biloba was quite popular for memory 20+ years ago, and perhaps had an uptick in popularity in the wake of the 1999 movie “Analyze This” in which the protagonist psychiatrist mentions taking ginkgo biloba, because “it helps my memory, and I forget what else”.
Here are a couple of studies from not long after that:
- A double-blind, placebo-controlled, randomized trial of Ginkgo biloba in cognitively intact older adults: neuropsychological findings
- Effects of Ginkgo biloba on mental functioning in healthy volunteers
In short:
- in the first study, it helped in standardized tests of memory and cognition (quite convincing)
- In the second study, it helped in subjective self-reports of mental wellness (also placebo-controlled)
On the other hand, here’s a more recent research review ten years later, that provides measures of memory, executive function and attention in 1132, 534 and 910 participants, respectively. That’s quite a few times more than the individual studies we cited above, by the way. They concluded:
❝We report that G. biloba had no ascertainable positive effects on a range of targeted cognitive functions in healthy individuals❞
Read: Is Ginkgo biloba a cognitive enhancer in healthy individuals? A meta-analysis
Our (10almonds) conclusion: we can’t say either way, on this one.
Does it have neuroprotective effects (i.e., against cognitive decline)?
Yes—probably by the same mechanism will discuss shortly.
- Ginkgo Biloba for Mild Cognitive Impairment and Alzheimer’s Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
- Treatment effects of Ginkgo biloba extract on symptoms of dementia: meta-analysis of randomized controlled trials
Can it help against depression and anxiety?
Yes—but probably indirectly by the mechanism we’ll get to in a moment:
- Role of Ginkgo biloba extract as an adjunctive treatment of elderly patients with depression
- Ginkgo biloba in generalized anxiety disorder and adjustment disorder with anxious mood
Likely this helps by improving blood flow, as illustrated better per:
Efficacy of ginkgo biloba extract as augmentation of venlafaxine in treating post-stroke depression
Which means…
Bonus: improved blood flow
This mechanism may support the other beneficial effects.
See: Ginkgo biloba extract improves coronary blood flow in healthy elderly adults
Is it safe?
Ginkgo biloba extract* is generally recognized as safe.
- However, as it improves blood flow, please don’t take it if you have a bleeding disorder.
- Additionally, it may interact badly with SSRIs, so you might want to avoid it if you’re taking such (despite it having been tested and found beneficial as an adjuvant to citalopram, an SSRI, in one of the studies above).
- No list of possible contraindications can be exhaustive, so please consult your own doctor/pharmacist before taking something new.
*Extract, specifically. The seeds and leaves of this plant are poisonous. Sometimes “all natural” is not better.
Where can I get it?
As ever, we don’t sell it (or anything else), but here’s an example product on Amazon
Enjoy!

Practical Optimism – by Dr. Sue Varma
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 how to get your brain onto a more positive track (without toxic positivity), but there’s a lot more to be said than we can fit into an article, so here’s a whole book packed full with usable advice.
The subtitle claims “the art, science, and practice of…”, but mostly it’s the science of. If there’s art to be found here, then this reviewer missed it, and as for the practice of, well, that’s down to the reader, of course.
However, it is easy to use the contents of this book to translate science into practice without difficulty.
If you’re a fan of acronyms, initialisms, and other mnemonics (such as the rhyming “Name, Claim, Tame, and Reframe”), then you’ll love this book as they come thick and fast throughout, and they contribute to the overall ease of application of the ideas within.
The writing style is conversational but with enough clinical content that one never forgets who is speaking—not in the egotistical way that some authors do, but rather, just, she has a lot of professional experience to share and it shows.
Bottom line: if you’d like to be more optimistic without delving into the delusional, this book can really help a lot with that (in measurable ways, no less!).

Considering taking Wegovy to lose weight? Here are the risks and benefits – and how it differs from Ozempic
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 weight-loss drug Wegovy is now available in Australia.
Wegovy is administered as a once-weekly injection and is approved specifically for weight management. It’s intended to be used in combination with a reduced-energy diet and increased physical activity.
So how does Wegovy work and how much weight can you expect to lose while taking it? And what are the potential risks – and costs – for those who use it?
Let’s look at what the science says.
Halfpoint/Shutterstock What is Wegovy?
Wegovy is a brand name for the medication semaglutide. Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1RA). This means it makes your body’s own glucagon-like peptide-1 hormone, called GLP-1 for short, work better.
Normally when you eat, the body releases the GLP-1 hormone which helps signal to your brain that you are full. Semaglutides enhance this effect, leading to a feeling of fullness, even when you haven’t eaten.
Another role of GLP-1 is to stimulate the body to produce more insulin, a hormone which helps lower the level of glucose (sugar) in the blood. That’s why semaglutides have been used for several years to treat type 2 diabetes.
Wegovy is self-injected once a week. S Becker/Shutterstock How does Wegovy differ from Ozempic?
Like Wegovy, Ozempic is a semaglutide. The way Wegovy and Ozempic work in the body are essentially the same. They’re made by the same pharmaceutical company, Novo Nordisk.
But there are two differences:
1) They are approved for two different (but related) reasons.
In Australia (and the United States), Ozempic is approved for use to improve blood glucose levels in adults with type 2 diabetes. By managing blood glucose levels effectively, the medication aims to reduce the risk of major complications, such as heart disease.
Wegovy is approved for use alongside diet and exercise for people with a body mass index (BMI) of 30 or greater, or 27 or greater but with other conditions such as high blood pressure.
Wegovy can also be used in people aged 12 years and older. Like Ozempic, Wegovy aims to reduce the risk of future health complications, including heart disease.
2) They are both injected but come in different strengths.
Ozempic is available in pre-loaded single-dose pens with varying dosages of 0.25 mg, 0.5 mg, 1 mg, or 2 mg per injection. The dose can be slowly increased, up to a maximum of 2 mg per week, if needed.
Wegovy is available in prefilled single-dose pens with doses of 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, or 2.4 mg. The treatment starts with a dose of 0.25 mg once weekly for four weeks, after which the dose is gradually increased until reaching a maintenance dose of 2.4 mg weekly.
While it’s unknown what the impact of Wegovy’s introduction will be on Ozempic’s availability, Ozempic is still anticipated to be in low supply for the remainder of 2024.
Is Wegovy effective for weight loss?
Given Wegovy is a semaglutide, there is very strong evidence it can help people lose weight and maintain this weight loss.
A recent study found that over four years, participants taking Wevovy as indicated experienced an average weight loss of 10.2% body weight and a reduction in waist circumference of 7.7cm.
For those who stop taking the medication, analyses have shown that about two-thirds of weight lost is regained.
Wegovy can help people lose weight and maintain their weight loss – while they take the drug. Mladen Mitrinovic/Shutterstock What are the side effects of Wegovy?
The most common side effects are nausea and vomiting.
However, other serious side effects are also possible because of the whole-of-body impact of the medication. Thyroid tumours and cancer have been detected as a risk in animal studies, yet are rarely seen in human scientific literature.
In the four-year Wegovy trial, 16.6% of participants who received Wegovy (1,461 people) experienced an adverse event that led to them permanently discontinuing their use of the medication. This was higher than the 8.2% of participants (718 people) who received the placebo (with no active ingredient).
Side effects included gastrointestinal disorders (including nausea and vomiting), which affected 10% of people who used Wegovy compared to 2% of people who used the placebo.
Gallbladder-related disorders occurred in 2.8% of people who used Wegovy, and 2.3% of people who received the placebo.
Recently, concerns about suicidal thoughts and behaviours have been raised, after a global analysis reviewed more than 36 million reports of adverse events from semaglutide (Ozempic or Wegovy) since 2000.
There were 107 reports of suicidal thoughts and self-harm among people taking semaglutide, sadly including six actual deaths. When people stopped the medication, 62.5% found the thoughts went away. What we don’t know is whether dose, weight loss, or previous mental health status or use of antidepressants had a role to play.
Finally, concerns are growing about the negative effect of semaglutides on our social and emotional connection with food. Anecdotal and scientific evidence suggests people who use semaglutides significantly reduce their daily dietary intake (as anticipated) by skipping meals and avoiding social occasions – not very enjoyable for people and their loved ones.
How can people access Wegovy?
Wegovy is available for purchase at pharmacists with a prescription from a doctor.
But there is a hefty price tag. Wegovy is not currently subsidised through the Pharmaceutical Benefits Scheme, leaving patients to cover the cost. The current cost is estimated at around A$460 per month dose.
If you’re considering Wegovy, make an appointment with your doctor for individual advice.
