Sunflower Oil vs Canola Oil – Which is Healthier?

Our Verdict
When comparing sunflower oil to canola oil, we picked the sunflower oil.
Why?
They’re both terrible! But canola oil is worse. Sunflower oil is marketed as being higher in polyunsaturated fats, which it is, albeit not by much.
Canola oil is very bad for the heart, and sunflower oil is only moderately bad for the heart, to the point that it can be heart-neutral if used sparingly.
As seed oils, they are both sources of vitamin E, but you’d need to drink a cup of oil to get your daily dose, so please just eat some seeds (or nuts, or fruit, or something) instead. It can even be sunflower seeds if you like! Rapeseed* itself (the seed that canola oil is made from) isn’t really sold as a foodstuff, so that one’s less of an option.
*Fun fact: if you’re N. American and wondering what this “rapeseed” is, know that most of the rest of the Anglosphere calls canola oil “rapeseed oil”, as it’s made from rapeseed, which comes from a plant called rape, whose name is unrelated to the crime of the same name, and comes from rāpa, the Latin word for turnip. Anyway, “canola” is a portmanteau of “Canadian” and “Ola” meaning oil, and is a trademark that has made its way into generic use throughout N. America, as a less alarming name.
Back to health matters: while sunflower seeds are healthy in moderation, the ultraprocessed and refined sunflower and canola oils are not.
Canola oil has also been found to be implicated in age-related cognitive decline, whereas sunflower oil has had mixed results in that regard.
In summary
Sunflower oil is relatively, and we stress relatively, healthier than canola oil. Please use a healthier oil than either if you can. Olive oil is good for most things, and if you need something with a higher smoke point (and/or less distinctive flavor), consider avocado oil, which is also very healthy and whose smoke point is even higher than the seed oils we’ve been discussing today.

Half Of Americans Over 50 Have Hemorrhoids, But They Can Be Prevented!
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’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Hello. I was hoping you could give some useful tips about how to avoid a painful ailment that has affected Ernest Hemingway, Karl Marx, David Livingstone, Napoleon, Marilyn Monroe, King Alfred, and Martin Luther, and, I confess, me from time to time … namely, hemorrhoids. Help!❞
Firstly: that list could be a lot longer! We don’t have global stats, but in the US for example, half of adults over 50 have hemorrhoids.
So, you’re certainly not alone. People just don’t talk about it.
But, there are preventative things you can do:
Fiber, fiber, fiber. See also:
Level-Up Your Fiber Intake! (Without Difficulty Or Discomfort)
Hydrate, hydrate, hydrate.
This one’s simple enough. If you are dehydrated, constipation is more likely, and with it, hemorrhoids.
Watch your meds…
Some medications can cause constipation—painkillers containing codeine are a common culprit, for example.
When you go, go!
Not only can prolonged straining promote hemorrhoids, but also (if you’ll pardon the phrasing—there’s only so delicately we can say this) simply sitting with things partway “open” down there is not good for its health; things can quickly become irritated, and that can lead to hemorrhoids.
So: when you go, go. Leave your phone in another room!
Wash—but carefully.
Beyond your normal showering/bathing routine, a bidet is a great option for keeping things happy down there, if you have that option available to you.
However, if you have hemorrhoids, don’t use soap, as this can cause irritation and make it worse.
Warm water is fine, as is a salt bath, and pat dry and/or use gentle wet-wipes rather than rougher paper.
You can follow up with a hemorrhoid cream of your choice (or hydrocortisone, unless that’s contraindicated by another condition you have)
Know when to seek help
Hemorrhoids will usually go away by themselves if not exacerbated. But if it’s getting unduly difficult, and/or you’re bleeding down there, it’s time to see a doctor.
Note on bleeding: even if you’re 100% sure you have hemorrhoids, there are still other reasons you could be bleeding, and so it needs checking out.
Hemorrhoid treatment, if needed, will vary depending on severity. Beyond creams and lotions, there are other options that are less fun but sometimes necessary, including injections, electrotherapy, banding, or surgery.
Take care!

Cynthia’s Thoughts on Intermittent Fasting
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 Myth of Breakfast and Snacking
Here at 10almonds we love addressing misconceptions in the health world.
When it comes to eating habits and fasting, we’ve written our own pieces on how to break your fast (otherwise known as break-fast, or breakfast), alongside a general breakdown of intermittent fasting, and a much-requested piece on fasting specifically for women.
Cynthia Thurlow, though, instead of just writing a few articles, has dedicated the majority of her working years to intermittent fasting and, in her TEDx talk (below), makes a strong argument challenging the long-held belief that breakfast is the most important meal of the day.
Cynthia Thurlow’s Two Main Points
Thurlow argues that it’s not what you eat but when you eat that has a more profound impact on health and aging. And she argues this is crucial regardless of your age.
Complementing her views on fasting are her views on snacking; she argues that snacking all day long is outdated advice and can overtax the digestive system, leading to various health issues.
Practical Tips for Starting Intermittent Fasting
To begin intermittent fasting, Thurlow suggests starting with a 12-13 hour fasting window and gradually increasing it to 16 hours.
In terms of food choice, she recommends eating whole, unprocessed foods during eating periods as well as staying well-hydrated with water, coffee, or tea.
But you won’t see results immediately; Thurlow advises giving the strategy a solid 30 days to see results and consulting a healthcare provider if there are any existing health conditions.
You can dive deeper and join the 15 million other people who have listened to her thoughts on fasting by watching her TEDx talk below:

How To April Fool Yourself Into Having A Nutrient-Dense Diet!
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.
These nutrient-dense foods pack such a punch you only need a bit added to your meal…
- “Have 5 servings of fruit per day”—popular wisdom in the West
- “Have 7 servings of fruit per day!”—generally held as the norm in Japan
- “Have these 12 things that are mostly fruit & veg & nuts each day”—Dr. Greger’s Daily Dozen
- “Does the pickle that comes with a burger count?”—an indication of how much many people struggle.
For what it’s worth: pickles are a good source of some minerals (and some healthy gut bacteria too), but are generally too high in sodium to be healthy for most people beyond in the most modest moderation.
But! It can be a lot easier, and without sitting down to a salad buffet every day!
Here are some sneaky tips:
(call it our nod to April Fool’s Day, because tricking yourself into eating more healthily is a top-tier prank)
Beyond soups and smoothies
Soups and smoothies are great, because we can take a lot of nutrients that way without actually oing much eating. And if we’ve a want or need to hide something, blending it does a fine job. However, we’re confident you already know how to make soups and smoothies. So…
Sauces are another excellent place to put nutrients—and as a bonus, homemade sauces will mean skipping on the store-bought sauces whose ingredients all-too-often look something like “sugar, water, spirit vinegar, glucose-fructose syrup, modified maize starch, maltodextrin, salt…”
Top things to use as a main base ingredient in sauces:
- Tomato purée—so much lycopene, and great vitamins too! Modest flavour, but obviously only sensible for what you intend to be a tomato-based sauce. Use it to make anything from marinara sauce to ketchup, sweet-and-sour to smoky barbecue.
- Lentils/beans—if unsure, red lentils or haricot beans have a very mild taste, and edamame beans are almost not-there, flavor-wise. But cooked and blended smooth, these are high-protein, iron-rich, flavonoid-heavy, and a good source of fiber too. Can be used as the base of so many savory creamy sauces!
- Corn—that yellow color? It’s all the lutein. Home-made creamed corn goes great as a dipping sauce! Added spices optional.
Vegetables that punch above their weight
Sometimes, you might not want to eat much veg, but a small edible side-dish could be appealing, or even a generous garnish. In those cases, if you choose wisely, you can have a lot of nutrients in a tiny portion. Here are some that have an absurd nutrient-to-size ratio:
Cacao nibs—one for the dessert-lovers here, but can also garnish a frothy coffee, your morning overnight oats, or if we’re honest, can also just be snacked on! And they keep for ages. Botanically technically a fruit, but we’re going to throw it in here. As for health qualities? Where to begin…
They:
- are full of antioxidants and fight inflammation
- boost immune health
- help control blood sugar levels
- improve vascular function and heart health
- and even fight cancer, which is a many-headed beast, but for example:
…which is starting to look like a pattern, isn’t it? It’s good against cancer.
Brussels sprouts—if your knee-jerk reaction here wasn’t one of great appeal, then consider: these are delicious if done right.
Buy them fresh, not frozen (nothing nutritionally wrong with frozen if you like them—we’re just doing the extra-level tastiness here). Wash them and peel them, then cut twice from the top to almost-the-bottom, to quarter them in a way that they still stay in one piece. Rub them (or if you’re going easier on the fats, spray them) with a little olive oil, a tiny touch of lemon juice, and sprinkle a little cracked black pepper. Sautée them. We know people will advise roasting, which is also great, but try the sautée approach, and thank us later.
Four sprouts is already a sufficient daily serving of cruciferous vegetables, and provides so many health benefits, with not just a stack of vitamins and minerals, but also have anti-cancer properties, are great for your heart in multiple ways, and reduce inflammation too. They’re literally one of the healthiest foods out there and you only need a tiny portion to benefit.
Kale—Don’t like the taste/texture? That’s OK, read on… No surprises here, but it’s crammed with vitamins and minerals.
- If you don’t care for the bitter taste, cooking it (such as by steaming it) takes that away.
- If you don’t care for the texture, baking it with a little sprayed-on olive oil changes that completely (and is how “kale chips” are made).
- If you don’t care for either? Do the “kale chips” thing mentioned above, but do it on a lower heat for longer—dry it out, basically. Then either blend it in a food processor, or by hand with a pestle and mortar (it turns to powder very easily, so this won’t be hard work), and you now have a very nutrient-dense powder that tastes of very little. While fries are not a health food, an example here is that you can literally dust fries with it and they won’t taste any different but you got a bunch of vitamins and minerals added from a whole food source.
- If going for the above approach, do it in batch and make yourself a jar of it to keep handy with your seasonings collection!
Bell peppers—Working hard to justify their high prices in the grocery store, these are very high in vitamins, especially rich in carotenoids, including lutein, and as a bonus, they’re also full of antioxidants. So, slice some and throw them at whatever else you’re cooking, and you’ve added a lot of nutrients for negligible effort.
Garlic—once you’ve done the paperwork, garlic not only makes bland meals delicious, but is also a treasure trove of micronutrients. It has a stack of vitamins and minerals, and also contains allicin. If you’ve not heard of that one, it’s the compound in garlic that is so good for blood pressure and heart health. See for example:
- Lipid-lowering effects of time-released garlic
- Garlic extract lowers blood pressure in patients with hypertension
- Garlic extract reduces blood pressure in hypertensives
If an apple a day keeps the doctor away, just imagine what a bulb of garlic can do (come on, we can’t be the only ones who measure garlic by the bulb instead of by the clove, right?)!
But in seriousness: measure garlic with your heart—have lots or a little, per your preference. The whole point here is that even a little of these superfoods can make a huge difference to your health!

Can You Reverse Gray Hair? A Dermatologist Explains
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.
Betteridge’s Law of Headlines states “any headline that ends in a question mark can be answered by the word no“—it’s not really a universal truth, but it’s true surprisingly often, and, as board certified dermatologist “The Beauty MD” Dr. Sam Ellis explains, it’s true in this case.
But, all is not lost.
Physiological Factors
Hair color is initially determined by genes and gene expression, instructing the body to color it with melanin (brown and black) and/or pheomelanin (blonde and red). If and when the body produces less of those pigments, our hair will go gray.
Factors that affect if/when our hair will go gray include:
- Genetics: primary determinant, essentially a programmed change
- Age: related to the above, but critically, the probability of going gray in any given year increases with age
- Ethnicity: the level of melanin in our skin is an indicator of how long we are likely to maintain melanin in our hair. Black people with the darkest skintones will thus generally go gray last, whereas white people with the lightest skintones will generally go gray first, and so on for a spectrum between the two.
- Medical conditions: immune conditions such as vitiligo, thyroid disease, and pernicious anemia promote an earlier loss of pigmentation
- Stress: oxidative stress, mainly, so factors like smoking will cause earlier graying. But yes, also chronic emotional stress does lead to oxidative stress too. Interestingly, this seems to be more about norepinephrine than cortisol, though.
- Nutrient deficiencies: the body can make a lot of things, but it needs the raw ingredients. Not having the right amounts of important vitamins and minerals will result in a loss of pigmentation (amongst other more serious problems). Vitamins B6, B9, and B12 are talked about in the video, as are iron and zinc. Copper is also needed for some hair colors. Selenium is needed for good hair health in general (but not too much, as an excess of selenium paradoxically causes hair loss), and many related things will stop working properly without adequate magnesium. Hair health will also benefit a lot from plenty of vitamin B7.
So, managing the above factors (where possible; obviously some of the above aren’t things we can influence) will result in maintaining one’s hair pigment for longer. As for texture, by the way, the reason gray hair tends to have a rougher texture is not for the lack of pigment itself, but is due to decreased sebum production. Judicious use of exogenous hair oils (e.g. argan oil, coconut oil, or whatever your preference may be) is a fine way to keep your grays conditioned.
However, once your hair has gone gray, there is no definitive treatment with good evidence for reversing that, at present. Dye it if you want to, or don’t. Many people (including this writer, who has just a couple of streaks of gray herself) find gray hair gives a distinguished look, and such harmless signs of age are a privilege not everyone gets to reach, and thus may be reasonably considered a cause for celebration

You Are Not a Before Picture – by Alex Light
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’s that time of year, and many of us are looking at what we’ll do in the coming days, weeks, and months to level-up our health. So… Is this a demotivational book?
Quite the opposite! It’s rather a case of an often much-needed reminder to ensure that our plans are really our own, and really are what’s best for us. Why wouldn’t they be, you ask?
Much of diet culture (ubiquitous! From magazine covers to movie stars to the models advertising anything from health insurance to water filters) has us reaching for “body goals” that are not possible without a different skeleton and genes and compromises and post-production edits.
Alex Light—herself having moved from the fashion and beauty industry into health education—sets out in a clear, easy-reading manner, how we can look after ourselves, not be neglectful of our bodies, and/but also not get distracted into unhelpful, impossible, castles-in-the-air.
Bottom line: you cannot self-hate your way into good health, and good health will always be much more attainable than a body that’s just not yours. This book can help you sort out which is which.

The Path to a Better Tuberculosis Vaccine Runs Through Montana
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.
A team of Montana researchers is playing a key role in the development of a more effective vaccine against tuberculosis, an infectious disease that has killed more people than any other.
The BCG (Bacille Calmette-Guérin) vaccine, created in 1921, remains the sole TB vaccine. While it is 40% to 80% effective in young children, its efficacy is very low in adolescents and adults, leading to a worldwide push to create a more powerful vaccine.
One effort is underway at the University of Montana Center for Translational Medicine. The center specializes in improving and creating vaccines by adding what are called novel adjuvants. An adjuvant is a substance included in the vaccine, such as fat molecules or aluminum salts, that enhances the immune response, and novel adjuvants are those that have not yet been used in humans. Scientists are finding that adjuvants make for stronger, more precise, and more durable immunity than antigens, which create antibodies, would alone.
Eliciting specific responses from the immune system and deepening and broadening the response with adjuvants is known as precision vaccination. “It’s not one-size-fits-all,” said Ofer Levy, a professor of pediatrics at Harvard University and the head of the Precision Vaccines Program at Boston Children’s Hospital. “A vaccine might work differently in a newborn versus an older adult and a middle-aged person.”
The ultimate precision vaccine, said Levy, would be lifelong protection from a disease with one jab. “A single-shot protection against influenza or a single-shot protection against covid, that would be the holy grail,” Levy said.
Jay Evans, the director of the University of Montana center and the chief scientific and strategy officer and a co-founder of Inimmune, a privately held biotechnology company in Missoula, said his team has been working on a TB vaccine for 15 years. The private-public partnership is developing vaccines and trying to improve existing vaccines, and he said it’s still five years off before the TB vaccine might be distributed widely.
It has not gone unnoticed at the center that this state-of-the-art vaccine research and production is located in a state that passed one of the nation’s most extreme anti-vaccination laws during the pandemic in 2021. The law prohibits businesses and governments from discriminating against people who aren’t vaccinated against covid-19 or other diseases, effectively banning both public and private employers from requiring workers to get vaccinated against covid or any other disease. A federal judge later ruled that the law cannot be enforced in health care settings, such as hospitals and doctors’ offices.
In mid-March, the Bill & Melinda Gates Medical Research Institute announced it had begun the third and final phase of clinical trials for the new vaccine in seven countries. The trials should take about five years to complete. Research and production are being done in several places, including at a manufacturing facility in Hamilton owned by GSK, a giant pharmaceutical company.
Known as the forgotten pandemic, TB kills up to 1.6 million people a year, mostly in impoverished areas in Asia and Africa, despite its being both preventable and treatable. The U.S. has seen an increase in tuberculosis over the past decade, especially with the influx of migrants, and the number of cases rose by 16% from 2022 to 2023. Tuberculosis is the leading cause of death among people living with HIV, whose risk of contracting a TB infection is 20 times as great as people without HIV.
“TB is a complex pathogen that has been with human beings for ages,” said Alemnew Dagnew, who heads the program for the new vaccine for the Gates Medical Research Institute. “Because it has been with human beings for many years, it has evolved and has a mechanism to escape the immune system. And the immunology of TB is not fully understood.”
The University of Montana Center for Translational Medicine and Inimmune together have 80 employees who specialize in researching a range of adjuvants to understand the specifics of immune responses to different substances. “You have to tailor it like tools in a toolbox towards the pathogen you are vaccinating against,” Evans said. “We have a whole library of adjuvant molecules and formulations.”
Vaccines are made more precise largely by using adjuvants. There are three basic types of natural adjuvants: aluminum salts; squalene, which is made from shark liver; and some kinds of saponins, which are fat molecules. It’s not fully understood how they stimulate the immune system. The center in Missoula has also created and patented a synthetic adjuvant, UM-1098, that drives a specific type of immune response and will be added to new vaccines.
One of the most promising molecules being used to juice up the immune system response to vaccines is a saponin molecule from the bark of the quillay tree, gathered in Chile from trees at least 10 years old. Such molecules were used by Novavax in its covid vaccine and by GSK in its widely used shingles vaccine, Shingrix. These molecules are also a key component in the new tuberculosis vaccine, known as the M72 vaccine.
But there is room for improvement.
“The vaccine shows 50% efficacy, which doesn’t sound like much, but basically there is no effective vaccine currently, so 50% is better than what’s out there,” Evans said. “We’re looking to take what we learned from that vaccine development with additional adjuvants to try and make it even better and move 50% to 80% or more.”
By contrast, measles vaccines are 95% effective.
According to Medscape, around 15 vaccine candidates are being developed to replace the BCG vaccine, and three of them are in phase 3 clinical trials.
One approach Evans’ center is researching to improve the new vaccine’s efficacy is taking a piece of the bacterium that causes TB, synthesizing it, and combining it with the adjuvant QS-21, made from the quillay tree. “It stimulates the immune system in a way that is specific to TB and it drives an immune response that is even closer to what we get from natural infections,” Evans said.
The University of Montana center is researching the treatment of several problems not commonly thought of as treatable with vaccines. They are entering the first phase of clinical trials for a vaccine for allergies, for instance, and first-phase trials for a cancer vaccine. And later this year, clinical trials will begin for vaccines to block the effects of opioids like heroin and fentanyl. The University of Montana received the largest grant in its history, $33 million, for anti-opioid vaccine research. It works by creating an antibody that binds with the drug in the bloodstream, which keeps it from entering the brain and creating the high.
For now, though, the eyes of health care experts around the world are on the trials for the new TB vaccines, which, if they are successful, could help save countless lives in the world’s poorest places.
