The Healthiest Drumstick
Moringa oleifera is a tree, whose leaves and pods have medicinal properties (as well as simply being very high in nutrients). It’s also called the drumstick tree in English, but equally often it’s referred to simply as Moringa. It has enjoyed use in traditional medicine for thousands of years, and its many benefits have caught scientists’ attention more recently. For an overview before we begin, see:
Now, let’s break it down…
Anti-inflammatory
It is full of antioxidants, which we’ll come to shortly, and they have abundant anti-inflammatory effects. Research into these so far has mostly beennon-human animal studies or else in vitro, hence the guarded “potential” for now:
Potential anti-inflammatory phenolic glycosides from the medicinal plant Moringa oleifera fruits
Speaking of potential though, it has been found to also reduce neuroinflammation specifically, which is good, because not every anti-inflammatory agent does that:
Antioxidant
It was hard to find studies that talked about its antioxidant powers that didn’t also add “and this, and this, and this” because of all its knock-on benefits, for example:
❝The results indicate that this plant possesses antioxidant, hypolipidaemic and antiatherosclerotic activities and has therapeutic potential for the prevention of cardiovascular diseases.
These effects were at degrees comparable to those of simvastatin.❞
~ Dr. Pilaipark Chumark et al.
Likely a lot of its benefits in these regards come from the plant’s very high quercetin content, because quercetin does that too:
Quercetin reduces blood pressure in hypertensive subjects

Antidiabetic
It also has been found to lower fasting blood sugar levels by 13.5%:
Anti-arsenic?
We put a question mark there, because studies into this have only been done with non-human animals such as mice and rats so far, largely because there are not many human volunteers willing to sign up for arsenic poisoning (and no ethics board would pass it anyway).
However, as arsenic contamination in some foods (such as rice) is a big concern, this is very promising. Here are some example studies, with mice and rats respectively:
- Protective effects of Moringa oleifera Lam. leaves against arsenic-induced toxicity in mice
- Therapeutic effects of Moringa oleifera on arsenic-induced toxicity in rats
Is it safe?
A popular food product through parts of Africa and (especially) South & West Asia, it has a very good safety profile. Generally the only health-related criticism of it is that it contains some anti-nutrients (that hinder bioavailability of its nutrients), but the nutrients outweigh the antinutrients sufficiently to render this a trifling trivium.
In short: as ever, do check with your doctor/pharmacist to be sure, but in general terms, this is about as safe as most vegan whole foods; it just happens to also be something of a superfood, which puts it into the “nutraceutical” category. See also:

Easy Ways To Fix Brittle, Dry, Wiry Hair
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.
Dr. Sam Ellis, a dermatologist, specializes in skin, hair, and nail care—and she’s here with professional knowledge:
Tackling the problem at the root
As we age, hair becomes less shiny, more brittle, coarse, wiry, or gray. More concerningly for many, hair thinning and shedding increases due to shortened growth phases and hormonal changes.
The first set of symptoms there are largely because sebum production decreases, leading to dry hair. It’s worth bearing in mind though, that factors like UV radiation, smoking, stress, and genetics contribute to hair aging too. So while we can’t do much about genetics, the modifiable factors are worth addressing.
Menopause and the corresponding “andropause” impact hair health, and hormonal shifts, not just aging, drive many hair changes. Which is good to know, because it means that HRT (mostly: topping up estrogen or testosterone as appropriate) can make a big difference. Additionally, topical/oral minoxidil and DHT blockers (such as finasteride or dutasteride) can boost hair density. These things come with caveats though, so do research any possible treatment plan before embarking on it, to be sure you are comfortable with all aspects of it—including that if you use minoxidil, while on the one hand it indeed works wonders, on the other hand, you’ll then have to keep using minoxidil for the rest of your life or your hair will fall out when you stop. So, that’s a commitment to be thought through before beginning.
Nutritional deficiencies (iron, zinc, vitamin D) and insufficient protein intake hinder hair growth, so ensure proper nutrition, with sufficient protein and micronutrients.
While we’re on the topic of “from the inside” things: take care to manage stress healthily, as stress negatively affects hair health.
Now, as for “from the outside”…
Dr. Ellis recommends moisturizing shampoos/conditioners; Virtue and Dove brands she mentions positively. She also recommends bond repair products (such as K18 and Olaplex) that restore hair integrity, and heat protectants (she recommends: Unite 7 Seconds) as well as hair oils in general that improve hair condition.

Shedding Some Obesity Myths
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.
Let’s shed some obesity myths!
There are a lot of myths and misconceptions surrounding obesity… And then there are also reactive opposite myths and misconceptions, which can sometimes be just as harmful!
To tackle them all would take a book, but in classic 10almonds style, we’re going to put a spotlight on some of the ones that might make the biggest difference:
True or False: Obesity is genetically pre-determined
False… With caveats.
Some interesting results have been found from twin studies and adoption studies, showing that genes definitely play some role, but lifestyle is—for most people—the biggest factor:
- The body-mass index of twins who have been reared apart
- An adoption study of human obesity
- Using a sibling-adoption design to parse genetic and environmental influences on children’s body mass index
In short: genes predispose; they don’t predetermine. But that predisposition alone can make quite a big difference, if it in turn leads to different lifestyle factors.
But upon seeing those papers centering BMI, let’s consider…
True or False: BMI is a good, accurate measure of health in the context of bodyweight
False… Unless you’re a very large group of thin white men of moderate height, which was the demographic the system was built around.
Bonus information: it was never intended to be used to measure the weight-related health of any individual (not even an individual thin white man of moderate height), but rather, as a tool to look at large-scale demographic trends.
Basically, as a system, it’s being used in a way it was never made for, and the results of that misappropriation of an epidemiological tool for individual health are predictably unhelpful.
To do a deep-dive into all the flaws of the BMI system, which are many, we’d need to devote a whole main feature just to that.
Update: we have now done so!
Here it is: When BMI Doesn’t Measure Up
True or False: Obesity does not meaningfully impact more general health
False… In more ways than one (but there are caveats)
Obesity is highly correlated with increased risk of all-cause mortality, and weight loss, correspondingly, correlates with a reduced risk. See for example:
So what are the caveats?
Let’s put it this way: owning a horse is highly correlated with increased healthy longevity. And while owning a horse may come with some exercise and relaxation (both of which are good for the health), it’s probably mostly not the horse itself that conveys the health benefits… it’s that someone who has the resources to look after a horse, probably has the resources to look after their own health too.
So sometimes there can be a reason for a correlation (it’s not a coincidence!) but the causative factor is partially (or in some cases, entirely) something else.
So how could this play out with obesity?
There’s a lot of discrimination in healthcare settings, unfortunately! In this case, it often happens that a thin person goes in with a medical problem and gets treated for that, while a fat person can go in with the same medical problem and be told “you should try losing some weight”.
Top tip if this happens to you… Ask: “what would you advise/prescribe to a thin person with my same symptoms?”
Other things may be more systemic, for example:
When a thin person goes to get their blood pressure taken, and that goes smoothly, while a fat person goes to get their blood pressure taken, and there’s not a blood pressure cuff to fit them, is the problem the size of the person or the size of the cuff? It all depends on perspective, in a world built around thin people.
That’s a trivial-seeming example, but the same principle has far-reaching (and harmful) implications in healthcare in general, e.g:
- Surgeons being untrained (and/or unwilling) to operate on fat people
- Getting a one-size-fits-all dose that was calculated using average weight, and now doesn’t work
- MRI machines are famously claustrophobia-inducing for thin people; now try not fitting in it in the first place
…and so forth. So oftentimes, obesity will be correlated with a poor healthcare outcome, where the problem is not actually the obesity itself, but rather the system having been set up with thin people in mind.
It would be like saying “Having O- blood type results in higher risks when receiving blood transfusions”, while omitting to add “…because we didn’t stock O- blood”.
True or False: to reduce obesity, just eat less and move more!
False… Mostly.
Moving more is almost always good for most people. When it comes to diet, quality is much more important than quantity. But these factors alone are only part of the picture!
But beyond diet and exercise, there are many other implicated factors in weight gain, weight maintenance, and weight loss, including but not limited to:
- Disrupted sleep
- Chronic stress
- Chronic pain
- Hormonal imbalances
- Physical disabilities that preclude a lot of exercise
- Mental health issues that add (and compound) extra levels of challenge
- Medications that throw all kinds of spanners into the works with their side effects
…and even just those first two things, diet and exercise, are not always so correlated to weight as one might think—studies have found that the difference for exercise especially is often marginal:

Chickpeas vs Peas – 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 chickpeas to peas, we picked the chickpeas.
Why?
Both are great! But…
In terms of macros, chickpeas have more protein, fiber, and carbs, the ratio of which latter two also gives them the lower glycemic index. It’s worth noting that peas are not far behind chickpeas here, but by the numbers, it’s a win for chickpeas in this category.
In the category of vitamins, chickpeas have more of vitamins B9, E, and choline, while peas have more of vitamins A, B1, B2, B3, B5, B6, C, and K. So, a win for peas this time!
When it comes to minerals, however, chickpeas have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while peas are not higher in any minerals.
Adding up the sections gives a 2:1 victory for chickpeas, but by all means enjoy either or both; diversity is good!

Zucchini vs Okra – 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 zucchini to okra, we picked the okra.
Why?
Looking at the macros first, okra has nearly 2x the protein and more than 3x the fiber (for about 2x the carbs).
In terms of vitamins, things are also quite one-sided; zucchini has a little more vitamin B2, while okra has a lot more of vitamins A, B1, B3, B5, B6, B9, C, E, K, and choline.
Nor does the mineral situation make any compelling counterargument; zucchini is higher only in sodium, while okra has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium*, selenium, and zinc.
*Actually it’s only a little more potassium. But the rest are with big margins of difference.
Both of these on-the-cusp-of-being-pungent vegetables have beneficial antioxidant polyphenols (especially various forms of quercetin), but okra has more.
In short: enjoy both, of course, but there’s a clear winner here and it’s okra.

‘Naked carbs’ and ‘net carbs’ – what are they and should you count them?
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.
According to social media, carbs come in various guises: naked carbs, net carbs, complex carbs and more.
You might be wondering what these terms mean or if all carbs are really the same. If you are into “carb counting” or “cutting carbs”, it’s important to make informed decisions about what you eat.
What are carbs?
Carbohydrates, or “carbs” for short, are one of the main sources of energy we need for brain function, muscle movement, digestion and pretty much everything our bodies do.
There are two classifications of carbs, simple and complex. Simple carbs have one or two sugar molecules, while complex carbs are three or more sugar molecules joined together. For example, table sugar is a simple carb, but starch in potatoes is a complex carb.
All carbs need to be broken down into individual molecules by our digestive enzymes to be absorbed. Digestion of complex carbs is a much slower process than simple carbs, leading to a more gradual blood sugar increase.
Fibre is also considered a complex carb, but it has a structure our body is not capable of digesting. This means we don’t absorb it, but it helps with the movement of our stool and prevents constipation. Our good gut bacteria also love fibre as they can digest it and use it for energy – important for a healthy gut.
What about ‘naked carbs’?
“Naked carbs” is a popular term usually used to refer to foods that are mostly simple carbs, without fibre or accompanying protein or fat. White bread, sugary drinks, jams, sweets, white rice, white flour, crackers and fruit juice are examples of these foods. Ultra-processed foods, where the grains are stripped of their outer layers (including fibre and most nutrients) leaving “refined carbs”, also fall into this category.
One of the problems with naked carbs or refined carbs is they digest and absorb quickly, causing an immediate rise in blood sugar. This is followed by a rapid spike in insulin (a hormone that signals cells to remove sugar from blood) and then a drop in blood sugar. This can lead to hunger and cravings – a vicious cycle that only gets worse with eating more of the same foods.
Naked carbs can make blood sugars spike then crash.
Pexels/Alexander GreyWhat about ‘net carbs’?
This is another popular term tossed around in dieting discussions. Net carbs refer to the part of the carb food that we actually absorb.
Again, fibre is not easily digestible. And some carb-rich foods contain sugar alcohols, such as sweeteners (like xylitol and sorbitol) that have limited absorption and little to no effect on blood sugar. Deducting the value of fibre and sugar alcohols from the total carbohydrate content of a food gives what’s considered its net carb value.
For example, canned pear in juice has around 12.3g of “total carbohydrates” per 100g, including 1.7g carb + 1.7g fibre + 1.9g sugar alcohol. So its net carb is 12.3g – 1.7g – 1.9g = 8.7g. This means 8.7g of the 12.3g total carbs impacts blood sugar.
The nutrition labels on packaged foods in Australia and New Zealand usually list fibre separately to carbohydrates, so the net carbs have already been calculated. This is not the case in other countries, where “total carbohydrates” are listed.
Does it matter though?
Whether or not you should care about net or naked carbs depends on your dietary preferences, health goals, food accessibility and overall nutritional needs. Generally speaking, we should try to limit our consumption of simple and refined carbs.
The latest World Health Organization guidelines recommend our carbohydrate intake should ideally come primarily from whole grains, vegetables, fruits and pulses, which are rich in complex carbs and fibre. This can have significant health benefits (to regulate hunger, improve cholesterol or help with weight management) and reduce the risk of conditions such as heart disease, obesity and colon cancer.
In moderation, naked carbs aren’t necessarily bad. But pairing them with fats, protein or fibre can slow down the digestion and absorption of sugar. This can help to stabilise blood sugar levels, prevent spikes and crashes and support personal weight management goals. If you’re managing diabetes or insulin resistance, paying attention to the composition of your meals, and the quality of your carbohydrate sources is essential.
A ketogenic (high fat, low carb) diet typically restricts carb intake to between 20 and 50g each day. But this carb amount refers to net carbs – so it is possible to eat more carbs from high-fibre sources.
Choose complex carbohydrates with lots of fibre.
ShutterstockSome tips to try
Some simple strategies can help you get the most out of your carb intake:
reduce your intake of naked carbs and foods high in sugar and white flour, such as white bread, table sugar, honey, lollies, maple syrup, jam, and fruit juice
opt for protein- and fibre-rich carbs. These include oats, sweet potatoes, nuts, avocados, beans, whole grains and broccoli
if you are eating naked carbs, dress them up with some protein, fat and fibre. For example, top white bread with a nut butter rather than jam
if you are trying to reduce the carb content in your diet, be wary of any symptoms of low blood glucose, including headaches, nausea, and dizziness
- working with a health-care professional such as an accredited practising dietitian or your GP can help develop an individualised diet plan that meets your specific needs and goals.

6 Kinds Of Drinks That Hasten Dementia
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.
Dr. William Li, most well-known for his diabetes expertise (remember that there are clear associations between diabetes and dementia), discusses drinks you might want to skip:
Here’s to your good health
The 6 kinds of drink are:
- Alcohol which is bad for pretty much everything and this is no exception. Can cause a deficiency of thiamine, brain-shrinking, neuroinflammation, oxidative stress, and resultant neuron damage.
- Soda / diet soda, the former of which is bad for the diabetes-dementia connection, and the latter of which is also usually (depends on the sweetener) harmful to the gut and thus the gut-brain connection.
- Fruit juices, especially if processed, as the high sugar and zero or nearly-zero fiber can lead to insulin resistance, affecting the brain’s energy processing. In particular, fruit juice drinks sweetened with high-fructose corn syrup (HFCS) can accumulated as fat in the brain (due to how the body processes fructose in the absence of fiber to slow it down), impacting cognition.
- Energy drinks, being basically the same as soda / diet soda, just now with added caffeine too.
- [Caffeinated] late-night coffee, can (shocking nobody) disrupt sleep, and chronic sleep deprivation contributes to the build-up of harmful brain plaques.
- Sports drinks, which (unless you’re super-sure about everything on the label; there are some good sports drinks out there) often contain HFCS in the US, along with various other additives that may not always be great for you. Also, the sodium content of electrolyte drinks are fine if you genuinely are actively sweating it out, but otherwise, can lead to high blood pressure, which is itself a dementia risk factor.
Better options include:
- decaffeinated coffee (or coffee enjoyed in the early afternoon)
- green tea
- turmeric-based drinks
Dr. Li mentions turmeric milk drinks, but unfermented dairy is generally inflammatory, so better to make it kefir (fermented milk drink) or plant-based. Or just have a turmeric tea; that works too.
Dr. Li also mentions berry smoothies, which are not nearly as bad as fruit juice, but still not as good as eating whole berries.
