So, no question/request too big or small
❝Avid coffee drinker so very interested in the results Also question Is there something that you could take or eat that would prevent the caffeine from stimulating the kidneys? I tried to drink decaf from morning to night not a good result! Thanks❞
That is a good question! The simple answer is “no” (but keep reading, because all is not lost)
There’s no way (that we yet know of) to proof the kidneys against the stimulating effect of caffeine. This is especially relevant because part of caffeine’s stimulating effect is noradrenergic, and that “ren” in the middle there? It’s about the kidneys. This is just because the adrenal gland is situated next to them (actually, it’s pretty much sitting on top of them), hence the name, but it does mean that the kidneys are about the hardest thing in the body to have not effected by caffeine.
However! The effects of caffeine in general can be softened a little with l-theanine (found in tea, or it can be taken as a supplement). It doesn’t stop it from working, but it makes the curve of the effect a little gentler, and so it can reduce some unwanted side effects.

Are plant-based burgers really bad for your heart? Here’s what’s behind the scary headlines
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’re hearing a lot about ultra-processed foods and the health effects of eating too many. And we know plant-based foods are popular for health or other reasons.
So it’s not surprising new research out this week including the health effects of ultra-processed, plant-based foods is going to attract global attention.
And the headlines can be scary if that research and the publicity surrounding it suggests eating these foods increases your risk of heart disease, stroke or dying early.
Here’s how some media outlets interpreted the research. The Daily Mail ran with:
Vegan fake meats are linked to increase in heart deaths, study suggests: Experts say plant-based diets can boost health – but NOT if they are ultra-processed
The New York Post’s headline was:
Vegan fake meats linked to heart disease, early death: study
But when we look at the study itself, it seems the media coverage has focused on a tiny aspect of the research, and is misleading.
So does eating supermarket plant-based burgers and other plant-based, ultra-processed foods really put you at greater risk of heart disease, stroke and premature death?
Here’s what prompted the research and what the study actually found.
Nina Firsova/Shutterstock Remind me, what are ultra-processed foods?
Ultra-processed foods undergo processing and reformulation with additives to enhance flavour, shelf-life and appeal. These include everything from packet macaroni cheese and pork sausages, to supermarket pastries and plant-based mince.
There is now strong and extensive evidence showing ultra-processed foods are linked with an increased risk of many physical and mental chronic health conditions.
Although researchers question which foods should be counted as ultra-processed, or if all of them are linked to poorer health, the consensus is that, generally, we should be eating less of them.
We also know plant-based diets are popular. These are linked with a reduced risk of chronic health conditions such as heart disease and stroke, cancer and diabetes. And supermarkets are stocking more plant-based, ultra-processed food options.
How about the new study?
The study looked for any health differences between eating plant-based, ultra-processed foods compared to eating non-plant based, ultra-processed foods. The researchers focused on the risk of cardiovascular disease (such as heart disease and stroke) and deaths from it.
Plant-based, ultra-processed foods in this study included mass-produced packaged bread, pastries, buns, cakes, biscuits, cereals and meat alternatives (fake meats). Ultra-processed foods that were not plant-based included milk-based drinks and desserts, sausages, nuggets and other reconstituted meat products.
The researchers used data from the UK Biobank. This is a large biomedical database that contains de-identified genetic, lifestyle (diet and exercise) and health information and biological samples from half a million UK participants. This databank allows researchers to determine links between this data and a wide range of diseases, including heart disease and stroke.
They used data from nearly 127,000 people who provided details of their diet between 2009 and 2012. The researchers linked this to their hospital records and death records. On average, the researchers followed each participant’s diet and health for nine years.
Plant-based, ultra-processed foods included in this study included packaged supermarket bread. doublelee/Shutterstock What did the study find?
With every 10% increase of total energy from plant-sourced, ultra-processed foods there was an associated 5% increased risk of cardiovascular disease (such as heart disease or stroke) and a 12% higher risk of dying from cardiovascular disease.
But for every 10% increase in plant-sourced, non-ultra-processed foods consumed there was an associated 7% lower risk of cardiovascular disease and a 13% lower risk of dying from cardiovascular disease.
The researchers found no evidence for an association between all plant-sourced foods (whether or not they were ultra-processed) and either an increased or decreased risk of cardiovascular disease or dying from it.
This was an observational study, where people recalled their diet using questionnaires. When coupled with other data, this can only tell us if someone’s diet is associated with a particular risk of a health outcome. So we cannot say that, in this case, the ultra-processed foods caused the heart disease and deaths from it.
Why has media coverage focused on fake meats?
Much of the media coverage has focused on the apparent health risks associated with eating fake meats, such as sausages, burgers, nuggets and even steaks.
These are considered ultra-processed foods. They are made by deconstructing whole plant foods such as pea, soy, wheat protein, nuts and mushrooms, and extracting the protein. They are then reformulated with additives to make the products look, taste and feel like traditional red and white meats.
However this was only one type of plant-based, ultra-processed food analysed in this study. This only accounted for an average 0.2% of the dietary energy intake of all the participants.
Compare this to bread, pastries, buns, cakes and biscuits, which are other types of plant-based, ultra-processed foods. These accounted for 20.7% of total energy intake in the study.
This image was at the top of the media release. Screenshot/Imperial It’s hard to say why the media focused on fake meat. But there is one clue in the media release issued to promote the research.
Although the media release did not mention the words “fake meat”, an image of plant-based burgers, sausages and meat balls or rissoles featured prominently.
The introduction of the study itself also mentions plant-sourced, ultra-processed foods, such as sausages, nuggets and burgers.
So it’s no wonder people can be confused.
Does this mean fake meats are fine?
Not necessarily. This study analysed the total intake of plant-based, ultra-processed foods, which included fake meats, albeit a very small proportion of people’s diets.
From this study alone we cannot tell if there would be a different outcome if someone ate large amounts of fake meats.
In fact, a recent review of fake meats found there was not enough evidence to determine their impact on health.
We also need more recent data to reflect current eating patterns of fake meats. This study used dietary data collected from 2009 to 2012, and fake meats have become more popular since.
What if I really like fake meat?
We have known for a while that ultra-processed foods can harm our health. This study tells us that regardless if an ultra-processed food is plant-based or not, it may still be harmful.
We know fake meat can contain large amounts of saturated fats (from coconut or palm oil), salt and sugar.
So like other ultra-processed foods, they should be eaten infrequently. The Australian Dietary Guidelines currently recommends people should only consume foods like this sometimes and in small amounts.
Are some fake meats healthier than others?
Check the labels and nutrition information panels. Look for those lowest in fat and salt. Burgers and sausages that are a “pressed cake” of minced ingredients such as nuts, beans and vegetables will be preferable to reformulated products that look identical to meat.
You can also eat whole plant-based protein foods such as legumes. These include beans, lentils, chickpeas and soy beans. As well as being high in protein and fibre, they also provide essential nutrients such as iron and zinc. Using spices and mushrooms alongside these in your recipes can replicate some of the umami taste associated with meat.

Apricot vs Banana – 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 apricot to banana, we picked the banana.
Why?
Both are great, and it was close!
In terms of macros, apricot has more protein, while banana has more carbs and fiber; both are low glycemic index foods, and we’ll call this category a tie.
In the category of vitamins, apricot has more of vitamins A, C, E, and K, while banana has more of vitamins B1, B2, B3, B5, B6, B7, B9, and choline, giving banana the win by strength of numbers. It’s worth noting though that apricots are one of the best fruits for vitamin A in particular.
When it comes to minerals, apricot has slightly more calcium, iron, and zinc, while banana has a lot more magnesium, manganese, potassium, and selenium, meaning a moderate win for banana here.
Adding up the sections makes for an overall win for banana—but of course, by all means enjoy either or both!

How can I stop using food to cope with negative emotions?
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.
Have you ever noticed changes in your eating habits when you are sad, bored or anxious?
Many people report eating either more, or less, as a way of helping them to cope when they experience difficult emotions.
Although this is a very normal response, it can take the pleasure out of eating, and can become distressing and bring about other feelings of shame and self-criticism.
Adding to the complexity of it all, we live in a world where diet culture is unavoidable, and our relationship to eating, food and body image can become complicated and confusing.
Drazen Zigic/Shutterstock Emotional eating is common
“Emotional eating” refers to the eating behaviours (typically eating more) that occur in response to difficult emotions.
Research shows around 20% of people regularly engage in emotional eating, with a higher prevalence among adolescents and women. In a study of more than 1,500 adolescents, 34% engaged in emotional eating while sad and 40% did so while anxious.
Foods consumed are often fast-foods and other energy-dense, nutrient-poor convenience foods.
Stress, strong emotions and depression
For some people, emotional eating was simply a habit formed earlier in life that has persisted over time.
But other factors might also contribute to the likelihood of emotional eating. The physiological effects of stress and strong emotions, for example, can influence hormones such as cortisol, insulin and glucose, which can also increase appetite.
Increased impulsivity (behaving before thinking things through), vulnerability to depression, a tendency to ruminate and difficulties regulating emotions also increase the likelihood of emotional eating.
Depression increases the likelihood of emotional eating. TommyStockProject/Shutterstock So what do you do?
First, know that fluctuations in eating are normal. However, if you find that the way you eat in response to difficult emotions is not working for you, there are a few things you can do.
Starting with small things that are achievable but can have a huge impact, such as prioritising getting enough sleep and eating regularly.
Then, you can start to think about how you handle your emotions and hunger cues.
Expand your emotional awareness
Often we label emotions as good or bad, and this can result in fear, avoidance, and unhelpful coping strategies such as emotional eating.
But it’s also important to differentiate the exact emotion. This might be feeling isolated, powerless or victimised, rather than something as broad as sad.
By noticing what the emotion is, we can bring curiosity to what it means, how we feel in our minds and bodies, and how we think and behave in response.
Tap into your feelings of hunger and fullness
Developing an intuitive way of eating is another helpful strategy to promote healthy eating behaviours.
Intuitive eating means recognising, understanding and responding to internal signals of hunger and fullness. This might mean tuning in to and acknowledging physical hunger cues, responding by eating food that is nourishing and enjoyable, and identifying sensations of fullness.
Intuitive eating encourages flexibility and thinking about the pleasure we get from food and eating. This style of eating also allows us to enjoy eating out with friends, and sample local delicacies when travelling.
It can also reduce the psychological distress from feeling out of control with your eating habits and the associated negative body image.
Try to be flexible in thinking about the pleasure of food and eating with friends. La Famiglia/Shutterstock When is it time to seek help?
For some people, the thoughts and behaviours relating to food, eating and body image can negatively impact their life.
Having the support of friends and family, accessing online resources and, in some instances, seeing a trained professional, can be very helpful.
There are many therapeutic interventions that work to improve aspects associated with emotional eating. These will depend on your situation, needs, stage of life and other factors, such as whether you are neurodivergent.
The best approach is to engage with someone who can bring compassion and understanding to your personal situation, and work with you collaboratively. This work might include:
- unpacking some of the patterns that could be underlying these emotions, thoughts and behaviours
- helping you to discover your emotions
- supporting you to process other experiences, such as trauma exposure
- developing a more flexible and intuitive way of eating.
One of the dangers that can occur in response to emotional eating is the temptation to diet, which can lead to disordered eating, and eating disorder behaviours. Indicators of a potential eating disorder can include:
- recent rapid weight loss
- preoccupation with weight and shape (which is usually in contrast to other people’s perceptions)
- eating large amounts of food within a short space of time (two hours or less) and feeling a sense of loss of control
- eating in secret
- compensating for food eaten (with vomiting, exercise or laxatives).
Evidence-based approaches can support people experiencing eating disorders. To find a health professional who is informed and specialises in this area, search the Butterfly Foundation’s expert database.

Which Sugars Are Healthier, And Which Are Just The Same?
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.
From Apples to Bees, and High-Fructose Cs
We asked you for your (health-related) policy on sugar. The trends were as follows:
- About half of all respondents voted for “I try to limit sugar intake, but struggle because it’s in everything”
- About a quarter of all respondents voted for “Refined sugar is terrible; natural sugars (e.g. honey, agave) are fine”
- About a quarter of all respondents voted for “Sugar is sugar and sugar is bad; I avoid it entirely”
- One (1) respondent voted for “Sugar is an important source of energy, so I consume plenty”
Writer’s note: I always forget to vote in these, but I’d have voted for “I try to limit sugar intake, but struggle because it’s in everything”.
Sometimes I would like to make my own [whatever] to not have the sugar, but it takes so much more time, and often money too.
So while I make most things from scratch (and typically spend about an hour cooking each day), sometimes store-bought is the regretfully practical timesaver/moneysaver (especially when it comes to condiments).
So, where does the science stand?
There has, of course, been a lot of research into the health impact of sugar.
Unfortunately, a lot of it has been funded by sugar companies, which has not helped. Conversely, there are also studies funded by other institutions with other agendas to push, and some of them will seek to make sugar out to be worse than it is.
So for today’s mythbusting overview, we’ve done our best to quality-control studies for not having financial conflicts of interest. And of course, the usual considerations of favoring high quality studies where possible Large sample sizes, good method, human subjects, that sort of thing.
Sugar is sugar and sugar is bad: True or False?
False and True, respectively.
- Sucrose is sucrose, and is generally bad.
- Fructose is fructose, and is worse.
Both ultimately get converted into glycogen (if not used immediately for energy), but for fructose, this happens mostly* in the liver, which a) taxes it b) goes very unregulated by the pancreas, causing potentially dangerous blood sugar spikes.
This has several interesting effects:
- Because fructose doesn’t directly affect insulin levels, it doesn’t cause insulin insensitivity (yay)
- Because fructose doesn’t directly affect insulin levels, this leaves hyperglycemia untreated (oh dear)
- Because fructose is metabolized by the liver and converted to glycogen which is stored there, it’s one of the main contributors to non-alcoholic fatty liver disease (at this point, we’re retracting our “yay”)
Read more: Fructose and sugar: a major mediator of non-alcoholic fatty liver disease
*”Mostly” in the liver being about 80% in the liver. The remaining 20%ish is processed by the kidneys, where it contributes to kidney stones instead. So, still not fabulous.
Fructose is very bad, so we shouldn’t eat too much fruit: True or False?
False! Fruit is really not the bad guy here. Fruit is good for you!
Fruit does contain fructose yes, but not actually that much in the grand scheme of things, and moreover, fruit contains (unless you have done something unnatural to it) plenty of fiber, which mitigates the impact of the fructose.
- A medium-sized apple (one of the most sugary fruits there is) might contain around 11g of fructose
- A tablespoon of high-fructose corn syrup can have about 27g of fructose (plus about 3g glucose)
Read more about it: Effects of high-fructose (90%) corn syrup on plasma glucose, insulin, and C-peptide in non-insulin-dependent diabetes mellitus and normal subjects
However! The fiber content (in fruit) mitigates the impact of the fructose almost entirely anyway.
And if you take fruits that are high in sugar and/but high in polyphenols, like berries, they now have a considerable net positive impact on glycemic health:
- Polyphenols and Glycemic Control
- Polyphenols and their effects on diabetes management: A review
- Dietary polyphenols as antidiabetic agents: Advances and opportunities
You may be wondering: what was that about “unless you have done something unnatural to it”?
That’s mostly about juicing. Juicing removes much (or all) of the fiber, and if you do that, you’re basically back to shooting fructose into your veins:
- Effect of Fruit Juice on Glucose Control and Insulin Sensitivity in Adults: A Meta-Analysis of 12 Randomized Controlled Trials
- Intake of Fruit, Vegetables, and Fruit Juices and Risk of Diabetes in Women
Natural sugars like honey, agave, and maple syrup, are healthier than refined sugars: True or False?
True… Sometimes, and sometimes marginally.
This is partly because of the glycemic index and glycemic load. The glycemic index scores tail off thus:
- table sugar = 65
- maple syrup = 54
- honey = 46
- agave syrup = 15
So, that’s a big difference there between agave syrup and maple syrup, for example… But it might not matter if you’re using a very small amount, which means it may have a high glycemic index but a low glycemic load.
Note, incidentally, that table sugar, sucrose, is a disaccharide, and is 50% glucose and 50% fructose.
The other more marginal health benefits come from that fact that natural sugars are usually found in foods high in other nutrients. Maple syrup is very high in manganese, for example, and also a fair source of other minerals.
But… Because of its GI, you really don’t want to be relying on it for your nutrients.
Wait, why is sugar bad again?
We’ve been covering mostly the more “mythbusting” aspects of different forms of sugar, rather than the less controversial harms it does, but let’s give at least a cursory nod to the health risks of sugar overall:
- Obesity and associated metabolic risk
- Main contributor to non-alcoholic fatty liver disease
- Increased risk of heart disease
- Insulin resistance and diabetes risk
- Cellular aging (shortened telomeres)
- 95% increased cancer risk
That last one, by the way, was a huge systematic review of 37 large longitudinal cohort studies. Results varied depending on what, specifically, was being examined (e.g. total sugar, fructose content, sugary beverages, etc), and gave up to 200% increased cancer risk in some studies on sugary beverages, but 95% increased risk is a respectable example figure to cite here, pertaining to added sugars in foods.

Make Your Coffee Heart-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.
Health-Hack Your Coffee
We have previously written about the general health considerations (benefits and potential problems) of coffee:
The Bitter Truth About Coffee (or is it?)
Today, we will broadly assume that you are drinking coffee (in general, not necessarily right now, though if you are, same!) and would like to continue to do so. We also assume you’d like to do so as healthily as possible.
Not all coffees are created equal
If you order a coffee in France or Italy without specifying what kind, the coffee you receive will be short, dark,
and handsomeand without sugar. Healthwise, this is not a bad starting point. However…- It will usually be espresso
- Or it may be what in N. America is called a French press (in Europe it’s just called a cafetière)
Both of these kinds of coffee mean that cafestol, a compound found in the oily part of coffee and which is known to raise LDL (“bad” cholesterol”), stays in the drink.
Read: Cafestol and Kahweol: A Review on Their Bioactivities and Pharmacological Properties
Also: Cafestol extraction yield from different coffee brew mechanisms
If you’re reading that second one and wondering what a mocha pot or a Turkish coffee is, they are these things:
- Mocha pot: a stovetop device used for making espresso without an espresso machine
- Turkish coffee pot: also a stovetop device; this thing makes some of the strongest coffee you have ever encountered. Turks usually add sugar (this writer doesn’t; but my taste in coffee been described as “coffee like a punch in the face”)
So, wonderful as they are for those of us who love strong coffee, they also produce the highest in-drink levels of cafestol. If you’d like to cut the cafestol (for example, if you are keeping an eye on your LDL), we recommend…
The humble filter coffee
Whether by your favorite filter coffee machine or a pour-over low-tech coffee setup of the kind you could use even without an electricity supply, the filter keeps more than just the coffee grinds out; it keeps the cafestol out too; most of it, anyway, depending on what kind of filter you use, and the grind of the coffee:
Physical characteristics of the paper filter and low cafestol content filter coffee brews
What about instant coffee?
It has very little cafestol in it. It’s up to you whether that’s sufficient reason to choose it over any other form of coffee (this coffee-lover could never)
Want to make any coffee healthier?
This one isn’t about the cafestol, but…
If you take l-theanine (see here for our previous main feature about l-theanine), the l-theanine acts as a moderator and modulator of the caffeine, amongst other benefits:

Forks Over Knives: Flavor! – by Darshana Thacker
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 important to not have to choose too much between health and flavor, because the outcome will never be a good one, either for your health or your happiness. And what’s bad for your happiness will ultimately not work out and thus will be bad for your general health, so, the question becomes: how to get both?
This book handles that nicely, delivering plant-based dishes that are also incidentally oil-free, and also either gluten-free or else there’s an obvious easy substitution to make it such. The flavor here comes from the ingredients as a whole, including the main ingredients as well as seasonings.
On the downside, occasionally those ingredients may be a little obscure if you don’t live in, say, San Francisco, and the ingredients weren’t necessarily chosen for cooking on a budget, either.
However, in most cases for most people it will, at worse, inspire you to try using an ingredient you don’t usually use—so that’s a good result.
The recipes are very clear and easy to follow, although not all are illustrated, and the “ready in…” times are about as accurate as they are for any cookbook, that is to say, it’s the time in which it conceivably can be done if (like the author, a head chef) you have a team of sous-chefs who have done a bunch of prep for you (e.g. sweet potato does not normally come in ½” dice; it comes in sweet potatoes) and laid everything out in little bowls mise-en-place style, and also you know the procedure well enough to not have to stop, hesitate, check anything, wash anything, wait for water to boil or anything else to heat up, or so forth. In other words, if you’re on your own in your home kitchen with normal domestic appliances, it’s going to take a little longer than for a professional in a professional kitchen with professional help.
But don’t let that detract from the honestly very good recipes.
Bottom line: if you’d like to level-up your plant-based cooking, this will definitely make your dishes that bit better!
