Time to go nuts for nuts!
Nuts, in popular perception, range from “basically the healthiest food anyone can eat” to “basically high calorie salty snacks”. And, they can be either!
Some notes, then:
- Raw is generally better that not
- Dry roasted is generally better than the kind with added oils
- Added salt is neither necessary nor good
Quick tip: if “roasted salted” are the cheapest or most convenient to buy, you can at least mitigate that by soaking them in warm water for 5 minutes, before rinsing and (if you don’t want wet nuts) drying.
You may be wondering: who does want wet nuts? And the answer is, if for example you’re making a delicious cashew and chickpea balti, the fact you didn’t dry them before throwing them in won’t make a difference.
Now, let’s do a quick run-down; we don’t usually do “listicles” but it seemed a good format here, so we’ve picked a top 5 for nutritional potency:
Almonds
We may have a bias. We accept it. But almonds are also one of the healthiest nuts around, and generally considered by most popular metrics the healthiest.
Not only are they high in protein, healthy fat, fiber, vitamins, and minerals, but they’re even a natural prebiotic that increases the populations of healthy gut bacteria, while simultaneously keeping down the populations of gut pathogens—what more can we ask of a nut?

Pistachios
Not only are these super tasty and fun to eat (and mindful eating is all but guaranteed, as shelling them by hand slows us down and makes us more likely to eat them one at a time rather than by the handful), but also they contain lots of nutrients and are lower in calories than most nuts, so they’re a great option for anyone who’d like to eat more nuts but is doing a calorie-controlled diet and doesn’t want to have half a day’s calories in a tiny dish of nuts.
Walnuts
Popularly associated with brain health (perhaps easy to remember because of their appearance), they really are good for the brain:
Check it out: Beneficial Effects of Walnuts on Cognition and Brain Health
Cashews
A personal favorite of this writer for their versatility in cooking, food prep, or just as a snack, they also do wonders for metabolic health:
Brazil nuts
The most exciting thing about these nuts is that they’re an incredibly potent source of selenium, which is important not just for hair/skin/nails as popularly marketed, but also for thyroid hormone production and DNA synthesis.
But don’t eat too many, because selenium is definitely one of those “you can have too much of a good thing” nutrients, and selenium poisoning can make your hair (however beautiful and shiny it got because of the selenium) fall out if you take too much.
Know the numbers: Brazil nuts and selenium—health benefits and risks
Bottom line on nuts:
- Nuts are a great and healthful part of almost anyone’s diet
- Obviously, if you have a nut allergy, then we’re sorry; this one won’t have helped you so much
- Almonds are one of the most healthful nuts out there
- Brazil nuts are incredibly potent, to the point where moderation is recommended
- A handful of mixed nuts per day is a very respectable option—when it comes to food and health, diversity is almost always good!

Making Friends With Your Gut (You Can Thank Us Later)
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.
Gut Health 101
We have so many microorganisms inside us, that by cell count, their cells outnumber ours more than ten-to-one. By gene count, we have 23,000 and they have more than 3,000,000. In effect, we are more microbe than we are human. And, importantly: they form a critical part of what keeps our overall organism ticking on.
Read all about it: The role of the gut microbiota in nutrition and health
Our trillions of tiny friends keep us alive, so it really really pays to return the favor.
But how?
Probiotics and fermented foods
You probably guessed this one, but it’d be remiss not to mention it first. It’s no surprise that probiotics help; the clue is in the name. In short, they help add diversity to your microbiome (that’s a good thing).
Read from the NIH: Probiotics: What You Need To Know
As for fermented foods, not every fermented food will boost your microbiota, but great options include…
- Fermented vegetables (sauerkraut, pickles, etc)
- You’ll often hear kimchi mentioned; that is also pickled vegetables, usually mostly cabbage. It’s just the culinary experience that differs. Unlike sauerkraut, kimchi is usually spiced, for example.
- Kombucha (a fermented sweet tea)
- Miso & tempeh (different preparations of fermented soy)
The health benefits vary based on the individual strains of bacteria involved in the fermentation, so don’t get too caught up on which is best.
The best one is the one you enjoy, because then you’ll have it regularly!
Feed them plenty of prebiotic fibers
Those probiotics you took? The bacteria in them eat the fiber that you can’t digest without them. So, feed them those sorts of fibers.
Great options include:
- Bananas
- Garlic
- Onions
- Whole grains
Read more: Effects of Probiotics, Prebiotics, and Synbiotics on Human Health
Don’t feed them sugar and sweeteners
Sugar and (and, counterintuitively, aspartame) can cause unfortunate gut microbe imbalances. Put simply, they kill some of your friends and feed some of your enemies. For example…
Candida, which we all have in us to some degree, feeds on sugar (including the sugar formed from breaking down alcohol, by the way) and refined carbs. Then it grows, and puts its roots through your intestinal walls, linking with your neural system. Then it makes you crave the very things that will feed it and allow it to put bigger holes in your intestinal walls.
Do not feed the Candida.
Don’t believe us? Read: Candida albicans-Induced Epithelial Damage Mediates Translocation through Intestinal Barriers
(That’s scientist-speak for “Candida puts holes in your intestines, and stuff can then go through those holes”)
And as for how that comes about, it’s like we said:
❝Colonization of the intestine and translocation through the intestinal barrier are fundamental aspects of the processes preceding life-threatening systemic candidiasis. In this review, we discuss the commensal lifestyle of C. albicans in the intestine, the role of morphology for commensalism, the influence of diet, and the interactions with bacteria of the microbiota.❞
Source: Candida albicans as a commensal and opportunistic pathogen in the intestine
The usual five things
- Good diet (Mediterranean Diet is good; plant-based version of it is by far the best for this)
- Good exercise (yes, really)
- Good sleep (helps them, and they’ll help you get better sleep in return)
- Limit or eliminate alcohol consumption (what a shocker)
- Don’t smoke (it’s bad for everything, including gut health)
One last thing you should know:
If you’re used to having animal products in your diet, and make a sudden change to all plants, your gut will object very strongly. This is because your gut microbiome is used to animal products, and a plant-based diet will cause many helpful microbes to flourish in great abundance, and many less helpful microbes will starve and die. And they will make it officially Not Fun™ for you.
So, you have two options to consider:
- Do it anyway, and sit it out (and believe us, you’ll be sitting), get the change over with quickly, and enjoy the benefits and much happier gut that follows.
- Make the change gradual. Reduce portions of animal products slowly, have “Meatless Mondays” etc, and slowly make the change over. This—for most people—is pretty comfortable, easy, and effective.
And remember: the effects of these things we’ve talked about today compound when you do more than one of them, but if you don’t want to take probiotics or really hate kombucha or absolutely won’t consider a plant-based diet or struggle to give up sugar or alcohol, etc… Just do what you can do, and you’ll still have a net improvement!

Kiwi vs Lime – 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 kiwi to lime, we picked the kiwi.
Why?
Looking at the macros first, kiwi has more protein, more carbs, and more fiber. As with most fruits, the fiber is the number we’re most interested in for health purposes; in this case, kiwi is just slightly ahead of lime on all three of those.
In terms of vitamins, kiwi has more of vitamins A, B2, B3, B6, B9, C, E, K, and choline, while lime has a tiny bit more vitamin B5. As in, the vitamin that’s in pretty much anything and is practically impossible to be deficient in unless you are literally starving to death. You may be thinking: aren’t limes a famously good source of vitamin C? And yes, yes they are. But kiwis have >3x more. In other big differences, kiwis also have >6x more vitamin E and >67 times more vitamin K.
When it comes to minerals, kiwi has more calcium, copper, magnesium, manganese, phosphorus, potassium, and zinc, while lime has more iron and selenium. Another easy win for kiwis.
In short: enjoy both; both are good. But kiwis are the more nutritionally dense option by almost every way of measuring it.

Weight Vests Against Osteoporosis: Do They Really Build Bone?
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. Doug Lucas is a dual board-certified physician specializing in optimizing healthspan and bone health for women experiencing osteoporosis, perimenopause, and menopause. Here, he talks weight vests:
Worth the weight?
Dr. Lucas cites “Wolf’s Law”—bones respond to stress. A weighted vest adds stress, to help build bone density. That said, they may not be suitable for everyone (for example, in cases of severe osteoporosis or a recent vertebral fracture).
He also cites some studies:
- Erlanger Fitness Study (2004): participants with a weighted vest maintained or improved bone density compared to a control group, but there was no group with exercise alone, making it unclear if the vest itself had the biggest impact.
- Newer studies (2016, 2017): showed improved outcomes for groups wearing a weighted vest, but again lacked an exercise-only group for comparison.
- 2012 study: included three groups (control, weighted vest, exercise only). Results showed no significant bone density difference between vest and exercise-only groups, though the vest group showed better balance and motor control.
Dr. Lucas concludes that weighted vests are a useful tool while nevertheless not being a magic bullet for bone health. In other words, they can complement exercise but you will also be fine without. If you do choose to level-up your exercise by using a weight vest, then starting with 5–10% of body weight in a vest is often recommended, but it depends on individual circumstances. If in doubt, start low and build up. Wearing the vest for daily activities can be effective, but improper use (awkward positions or improper impact training) can increase injury risk, so do be careful with that.

How To Manage Your Mood With Food (8 Ways)
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.
It is hard to be mentally healthy for long without good diet. Food can not only affect our mood directly, but also indirectly because of how our brain works (or doesn’t, if we don’t have the right nutrients, or it is being sabotaged in some other dietary fashion).
Selecting the food for setting the mood
Mind, the mental health charity, have these advices to share (with some bonus notes of our own):
- Eat regularly: blood sugar peaks and troughs can heighten feelings of tiredness, irritability, or depression. Instead, enjoy foods that are high in energy but low in glycemic index, such as nuts, seeds, and oats—that way you’ll have plenty of energy, that lasts longer.
- Choose the right fats: omega-3 fatty acids are essential for the brain. So are omega-6 fatty acids, but it is rare to have a deficiency in omega-6, and indeed, many people have the ratio of omega-3 to omega-6 far too imbalanced in omega-6’s favor. So, focussing on getting more omega-3 fatty acids is important. Nuts and seeds are again great, as are avocados, eggs, and oily fish.
- Get a healthy amount of protein: and importantly, with a good mix of amino acids—so a variety of sources of protein is best. In particular, if you are vegan, paying attention to ensure you get a full spread of amino acids is critical, as not many plants have all the ones we need (soy does, though). The reason this is important for mood is because many of those amino acids double up as the building blocks of neurotransmitters, so they’re not entirely interchangeable.
- Stay hydrated: our bodies are famously made of mostly water, and our brain will not work well if it’s dehydrated. The human body can squeeze water out of almost anything that has water in it, but water from food (such as fruit, or soups) is best. If enjoying actual drinks, then herbal teas are excellent for hydration.
- Eat a rainbow of fruits and vegetables: these have many nutrients that are important for brain health, and the point of the colors is that most of those pigments are themselves nutrients. Additionally, the fiber content of fruits and vegetables is of topmost important for your heart, and as you’ll remember (we say it often, because it’s true): what’s good for your heart is good for your brain.
- Limit caffeine intake: for many people, excess caffeine can lead to feelings of anxiety, disrupt your sleep, and for everyone who has developed an addiction to it, it will cause withdrawal symptoms if stopped abruptly. Cutting back on caffeine, or even eliminating it, may improve your mood and sleep quality. Note, however, that if you have ADHD, then your brain’s physiological relationship with caffeine is a little different, and stimulants will be more beneficial (and less deleterious) for you than for most people. If unsure, speak with your doctor about this one.
- Support your gut health: because of the gut-brain axis (via the vagal nerve), and also because nearly all of our endogenous serotonin is made in the gut (along with other neurotransmitters/hormones), getting plenty of fiber is important, and probiotics can help too.
- Consider food intolerances: if you know you have one, then keep that in mind and tailor your diet accordingly. If you suspect you have one, seek a nutritionist’s help to find out for sure. These can affect many aspects of health, including mood, so should not be dismissed as a triviality.

Cheeky diet soft drink getting you through the work day? Here’s what that may mean for your health
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.
Many people are drinking less sugary soft drink than in the past. This is a great win for public health, given the recognised risks of diets high in sugar-sweetened drinks.
But over time, intake of diet soft drinks has grown. In fact, it’s so high that these products are now regularly detected in wastewater.
So what does the research say about how your health is affected in the long term if you drink them often?
Breakingpic/Pexels What makes diet soft drinks sweet?
The World Health Organization (WHO) advises people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.”
But most regular soft drinks contain a lot of sugar. A regular 335 millilitre can of original Coca-Cola contains at least seven teaspoons of added sugar.
Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources.
Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness.
Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight.
But while surveys of Australian adults and adolescents show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly.
Diet soft drinks contain artificial or natural sweeteners. Vintage Tone/Shutterstock What does the research say about aspartame?
The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the US and Australia. However, some researchers have raised concern about the long-term risks of consumption.
People who drink diet soft drinks regularly and often are more likely to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks.
The link was found even after accounting for other dietary and lifestyle factors (such as physical activity).
In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “possibly carcinogenic to humans” (carcinogenic means cancer-causing).
Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally.
Will diet soft drinks help manage weight?
Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management.
In 2022, the WHO conducted a systematic review (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management.
Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners.
But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity.
In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO advising artificial sweeteners should not be used to manage weight.
Studies in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven.
You can’t go wrong with water. hurricanehank/Shutterstock What about inflammation and dental issues?
There is some early evidence artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed.
High amounts of diet soft drinks have also been linked with liver disease, which is based on inflammation.
The consumption of diet soft drinks is also associated with dental erosion.
Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion.
Moderation is key
As with many aspects of nutrition, moderation is key with diet soft drinks.
Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term.
Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.

Dodging Dengue In The US
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.
Dengue On The Rise
We wrote recently about dengue outbreaks in the Americas, with Puerto Rico declaring an epidemic. Cases are now being reported in Florida too, and are likely to spread, so it’s good to be prepared, if your climate is of the “warm and humid” kind.
If you want to catch up on the news first, here you go:
- UN health agency cites tenfold increase in reported cases of dengue over the last generation
- Puerto Rico has declared an epidemic following a spike in dengue cases
- Dengue fever confirmed in Florida Keys as US on watch for rise in mosquito illness
Note: dengue is far from unheard of in Florida, but the rising average temperatures in each year mean that each year stands a good chance of seeing more cases than the previous. It’s been climbing since at least 2017, took a dip during the time of COVID restrictions keeping people at home more, and then for the more recent years has been climbing again since.
What actually is it?
Dengue is a viral, mosquito-borne disease, characterized by fever, vomiting, muscle pain, and a rash, in about 1 in 4 cases.
Which can sound like “you’ll know if you have it”, but in fact it’s usually asymptomatic for a week or more after infection, so, watch out!
What next, if those symptoms appear?
The good news is: the fever will usually last less than a week
The bad news is: a day or so after that the fever subsided, the more serious symptoms are likely to start—if they’re going to.
If you’re unlucky enough to be one of the 1 in 20 who get the serious symptoms, then you can expect abdominal cramps, repeat vomiting, bleeding from various orifices (you may not get them all, but all are possible), and (hardly surprising, given the previous items) “extreme fatigue and restlessness”.
If you get those symptoms, then definitely get to an ER as soon as possible, as dengue can become life-threatening within hours of such.
Read more: CDC | Symptoms of Dengue and Testing
While there is not a treatment for dengue per se, the Emergency Room will be better able to manage your symptoms and thus keep you alive long enough for them to pass.
If you’d like much more detail (on symptoms, seriousness, at-risk demographics, and prognosis) than what the CDC offers, then…
Read more: BMJ | Dengue Fever
Ok, so how do we dodge the dengue?
It sounds flippant to say “don’t get bitten”, but that’s it. However, there are tips are not getting bitten:
- Use mosquito-repellent, but it has to contain >20% DEET, so check labels
- Use mosquito nets where possible (doors, windows, etc, and the classic bed-tent net is not a bad idea either)
- Wear clothing that covers your skin, especially during the day—it can be light clothing; it doesn’t need to be a HazMat suit! But it does need to reduce the area of attack to reduce the risk of bites.
- Limit standing water around your home—anything that can hold even a small amount of standing water is a potential mosquito-breeding ground. Yes, even if it’s a crack in your driveway or a potted bromeliad.
