Our Verdict
When comparing Life Extension Multivitamins to Centrum Multivitamins, we picked the Life Extension.
Why?
The clue here was on the label: “two per day”. It’s not so that they can sell extra filler! It’s because they couldn’t fit it all into one.
While the Centrum Multivitamins is a (respectably) run-of-the-mill multivitamin (and multimineral) containing reasonable quantities of most vitamins and minerals that people supplement, the Life Extension product has the same plus more:
- More of the vitamins and minerals; i.e. more of them are hitting 100%+ of the RDA
- More beneficial supplements, including:
- Inositol, Alpha lipoic acid, Bio-Quercetin phytosome, phosphatidylcholine complex, Marigold extract, Apigenin, Lycopene, and more that we won’t list here because it starts to get complicated if we do.
We’ll have to write some main features on some of those that we haven’t written about before, but suffice it to say, they’re all good things.
Main take-away for today: sometimes more is better; it just necessitates then reading the label to check.

PS: it bears mentioning, since we are sometimes running brands against each other head-to-head in this section: nothing you see here is an advertisement/sponsor unless it’s clearly marked as such. We haven’t, for example, been paid by Life Extension or any agent of theirs, to write the above. It’s just our own research and conclusion.

Does intermittent fasting increase or decrease our risk of cancer?
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.
Research over the years has suggested intermittent fasting has the potential to improve our health and reduce the likelihood of developing cancer.
So what should we make of a new study in mice suggesting fasting increases the risk of cancer?
Stock-Asso/Shutterstock What is intermittent fasting?
Intermittent fasting means switching between times of eating and not eating. Unlike traditional diets that focus on what to eat, this approach focuses on when to eat.
There are lots of commonly used intermittent fasting schedules. The 16/8 plan means you only eat within an eight-hour window, then fast for the remaining 16 hours. Another popular option is the 5:2 diet, where you eat normally for five days then restrict calories for two days.
In Australia, poor diet contributes to 7% of all cases of disease, including coronary heart disease, stroke, type 2 diabetes, and cancers of the bowel and lung. Globally, poor diet is linked to 22% of deaths in adults over the age of 25.
Intermittent fasting has gained a lot of attention in recent years for its potential health benefits. Fasting influences metabolism, which is how your body processes food and energy. It can affect how the body absorbs nutrients from food and burns energy from sugar and fat.
What did the new study find?
The new study, published in Nature, found when mice ate again after fasting, their gut stem cells, which help repair the intestine, became more active. The stem cells were better at regenerating compared with those of mice who were either totally fasting or eating normally.
This suggests the body might be better at healing itself when eating after fasting.
However, this could also have a downside. If there are genetic mutations present, the burst of stem cell-driven regeneration after eating again might make it easier for cancer to develop.
Polyamines – small molecules important for cell growth – drive this regeneration after refeeding. These polyamines can be produced by the body, influenced by diet, or come from gut bacteria.
The findings suggest that while fasting and refeeding can improve stem cell function and regeneration, there might be a tradeoff with an increased risk of cancer, especially if fasting and refeeding cycles are repeated over time.
While this has been shown in mice, the link between intermittent fasting and cancer risk in humans is more complicated and not yet fully understood.
What has other research found?
Studies in animals have found intermittent fasting can help with weight loss, improve blood pressure and blood sugar levels, and subsequently reduce the risks of diabetes and heart disease.
Research in humans suggests intermittent fasting can reduce body weight, improve metabolic health, reduce inflammation, and enhance cellular repair processes, which remove damaged cells that could potentially turn cancerous.
However, other studies warn that the benefits of intermittent fasting are the same as what can be achieved through calorie restriction, and that there isn’t enough evidence to confirm it reduces cancer risk in humans.
What about in people with cancer?
In studies of people who have cancer, fasting has been reported to protect against the side effects of chemotherapy and improve the effectiveness of cancer treatments, while decreasing damage to healthy cells.
Prolonged fasting in some patients who have cancer has been shown to be safe and may potentially be able to decrease tumour growth.
On the other hand, some experts advise caution. Studies in mice show intermittent fasting could weaken the immune system and make the body less able to fight infection, potentially leading to worse health outcomes in people who are unwell. However, there is currently no evidence that fasting increases the risk of bacterial infections in humans.
So is it OK to try intermittent fasting?
The current view on intermittent fasting is that it can be beneficial, but experts agree more research is needed. Short-term benefits such as weight loss and better overall health are well supported. But we don’t fully understand the long-term effects, especially when it comes to cancer risk and other immune-related issues.
Since there are many different methods of intermittent fasting and people react to them differently, it’s hard to give advice that works for everyone. And because most people who participated in the studies were overweight, or had diabetes or other health problems, we don’t know how the results apply to the broader population.
For healthy people, intermittent fasting is generally considered safe. But it’s not suitable for everyone, particularly those with certain medical conditions, pregnant or breastfeeding women, and people with a history of eating disorders. So consult your health-care provider before starting any fasting program.

The Exercise That Protects Your Brain
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 Neuroscientist In The Gym
This is Dr. Wendy Suzuki. She’s a neuroscientist, and an expert in the neurobiology of memory, as well as neuroplasticity, and the role of exercise in neuroprotection.
We’ve sneakily semi-featured her before when we shared her Big Think talk:
Brain Benefits In Three Months… Through Walking?
Today we’re going to expand on that a little!
A Quick Recap
To share the absolute key points of that already fairly streamlined rundown:
- Exercise boosts levels of neurotransmitters such as dopamine and serotonin (and, which wasn’t mentioned there, noradrenaline)
- These are responsible for motivation, happiness, and focus (amongst other things)
- Persistent exercise boosts certain regions of the brain in particular, most notably the pre-frontal cortex and the hippocampi*
- These are responsible for planning and memory (amongst other things)
Dr. Suzuki advocates for stepping up your exercise routine if you can, with more exercise generally being better than less (unless you have some special medical reason why that’s not the case for you).
*often referred to in the singular as the hippocampus, but you have one on each side of your brain (unless a serious accident/incident destroyed one, but you’ll know if that applies to you, unless you lost both, in which case you will not remember about it).
What kind(s) of workout?
While a varied workout is best for overall health, for these brain benefits specifically, what’s most important is that it raises your heart rate.
This is why in her Big Think talk we shared before, she talks about the benefits of taking a brisk walk daily. See also:
If that’s not your thing, though (and/or is for whatever reason an inaccessible form of exercise for you), there is almost certainly some kind of High Intensity Interval Training that is a possibility for you. That might sound intimidating, but if you have a bit of floor and can exercise for one minute at a time, then HIIT is an option for you:
How To Do HIIT (Without Wrecking Your Body)
Dr. Suzuki herself is an ardent fan of “intenSati” which blends cardio workouts with yoga for holistic mind-and-body fitness. In fact, she loves it so much that she became a certified exercise instructor:
How much is enough?
It’s natural to want to know the minimum we can do to get results, but Dr. Suzuki would like us to bear in mind that when it comes to our time spent exercising, it’s not so much an expense of time as an investment in time:
❝Exercise is something that when you spend time on it, it will buy you time when you start to work❞
Read more: A Neuroscientist Experimented on Her Students and Found a Powerful Way to Improve Brain Function
Ok, but we really want to know how much!
Dr. Suzuki recommends at least three to four 30-minute exercise sessions per week.
Note: this adds up to less than the recommended 150 minutes of moderate exercise per week, but high-intensity exercise counts for twice the minutes for these purposes, e.g. 1 minute of high-intensity exercise is worth 2 minutes of moderate exercise.
How soon will we see benefits?
Benefits start immediately, but stack up cumulatively with continued long-term exercise:
❝My lab showed that a single workout can improve your ability to shift and focus attention, and that focus improvement will last for at least two hours. ❞
…which is a great start, but what’s more exciting is…
❝The more you’re working out, the bigger and stronger your hippocampus and prefrontal cortex gets. Why is that important?
Because the prefrontal cortex and the hippocampus are the two areas that are most susceptible to neurodegenerative diseases and normal cognitive decline in aging. ❞
In other words, while improving your heart rate through regular exercise will help prevent neurodegeneration by the usual mechanism of reducing neuroinflammation… It’ll also build the parts of your brain most susceptible to decline, meaning that when/if decline sets in, it’ll take a lot longer to get to a critical level of degradation, because it had more to start with.

Apple vs Pear – 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 apple to pear, we picked the pear.
Why?
Both are great! But there’s a category that puts pears ahead of apples…
Looking at their macros first, pears contain more carbs but also more fiber. Both are low glycemic index foods, though.
In the category of vitamins, things are moderately even: apples contain more of vitamins A, B1, B6, and E, while pears contain more of vitamins B3, B9, K, and choline. That’s a 4:4 split, and the two fruits are about equal in the other vitamins they both contain.
When it comes to minerals, pears contain more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. A resounding victory for pears, as apples are not higher in any mineral.
In short, if an apple a day keeps the doctor away, a pear should keep the doctor away for about a day and a half, based on the extra nutrients ← this is slightly facetious as medicine doesn’t work like that, but you get the idea: pears simply have more to offer. Apples are still great though! Enjoy both! Diversity is good.

Calm Your Mind with Food – by Dr. Uma Naidoo
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 the author of This Is Your Brain On Food, the psychiatrist-chef (literally, she is a Harvard-trained psychiatrist and an award-winning chef) is back with a more specific work, this time aimed squarely at what it says in the title; how to calm your mind with food.
You may be wondering: does this mean comfort-eating? And, well, not in the sense that term’s usually used. There will be eating and comfort will occur, but the process involves an abundance of nutrients, a minimization of health-deleterious ingredients, and a “for every chemical its task” approach. In other words, very much “nutraceuticals”, as our diet.
On which note: as we’ve come to expect from Dr. Naidoo, we see a lot of hard science presented simply and clearly, with neither undue sensationalization nor unnecessary jargon. We learn about the brain, the gut, relevant biology and chemistry, and build up from understanding ingredients to dietary patterns to having a whole meal plan, complete with recipes.
You may further be wondering: how much does it add that we couldn’t get from the previous book? And the answer is, not necessarily a huge amount, especially if you’re fairly comfortable taking ideas and creating your own path forwards using them. If, on the other hand, you’re a little anxious about doing that (as someone perusing this book may well be), then Dr. Naidoo will cheerfully lead you by the hand through what you need to know and do.
Bottom line: if not being compared to her previous book, this is a great standalone book with a lot of very valuable content. However, the previous book is a tough act to follow! So… All in all we’d recommend this more to people who want to indeed “calm your mind with food”, who haven’t read the other book, as this one will be more specialized for you.

Rainbow Roasted Potato Salad
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.
This salad has potatoes in it, but it’s not a potato salad as most people know it. The potatoes are roasted, but in a non-oily-dressing, that nevertheless leaves them with an amazing texture—healthy and delicious; the best of both worlds. And the rest? We’ve got colorful vegetables, we’ve got protein, we’ve got seasonings full of healthy spices, and more.
You will need
- 1½ lbs new potatoes (or any waxy potatoes; sweet potato is also a great option; don’t peel them, whichever you choose) cut into 1″ chunks
- 1 can / 1 cup cooked cannellini beans (or your preferred salad beans)
- 1 carrot, grated
- 2 celery stalks, finely chopped
- 3 spring onions, finely chopped
- ½ small red onion, finely sliced
- 2 tbsp white wine vinegar
- 1 tbsp balsamic vinegar
- 1 tbsp lemon juice
- 1 tbsp nutritional yeast
- 1 tsp garlic powder
- 1 tsp black pepper
- ½ tsp red chili powder
- We didn’t forget salt; it’s just that with the natural sodium content of the potatoes plus the savory flavor-enhancing properties of the nutritional yeast, it’s really not needed here. Add if you feel strongly about it, opting for low-sodium salt, or MSG (which has even less sodium).
- To serve: 1 cup basil pesto (we’ll do a recipe one of these days; meanwhile, store-bought is fine, or you can use the chermoula we made the other day, ignoring the rest of that day’s recipe and just making the chermoula component)
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven as hot as it goes!
2) Combine the potatoes, white wine vinegar, nutritional yeast, garlic powder, black pepper, and red chili powder, mixing thoroughly (but gently!) to coat.
3) Spread the potatoes on a baking tray, and roast in the middle of the oven (for best evenness of cooking); because of the small size of the potato chunks, this should only take about 25 minutes (±5mins depending on your oven); it’s good to turn them halfway through, or at least jiggle them if you don’t want to do all that turning.
4) Allow to cool while still on the baking tray (this allows the steam to escape immediately, rather than the steam steaming the other potatoes, as it would if you put them in a bowl).
5) Now put them in a serving bowl, and mix in the beans, vegetables, balsamic vinegar, and lemon juice, mixing thoroughly but gently
6) Add generous lashings of the pesto to serve; it should be gently mixed a little too, so that it’s not all on top.
Enjoy!

Fruit & Veg In The Fridge: Pros & Cons
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
❝What effect does refrigeration have on the nutritional value of fruit and vegetables??❞
It’s difficult to give a single definitive answer, because naturally there are a lot of different fruits and vegetables, and a lot of different climates. The answer may be different for tomatoes in Alaska vs bananas in Arizona!
However, we can still generalize at least somewhat
Refrigeration will generally slow down any degradation process, and in the case of fruit and vegetables, that can mean slowing down their “ripening” too, as applicable.
However…
Refrigeration will also impede helpful bioactivity too, and that includes quite a list of things.
Here’s a good study that’s quite illustrative; we’d summarize the conclusions but the rather long title already does that nicely:
So, this really is a case of “there are pros and cons, but probably more cons on balance”.
In practical terms, a good take-away from this can be twofold:
- don’t keep fruit and veg in the fridge unless the ambient temperature really requires it
- if the ambient temperature does require it, it’s best to get the produce in fresh each day if that’s feasible, to minimize time spent in the fridge
An extra thing not included there: often when it comes to the spoilage of fruit and veg, the problem is that it respires and oxidizes; reducing the temperature does lower the rate of those, but often a far better way is to remove the oxygen. So for example, if you get carried away and chop too many carrot batons for your hummus night, then putting them in a sealed container can go a long way to keeping them fresh.
