We know that we should eat for brain health, but often that knowledge doesn’t go a lot further than “we should eat some nuts… but also not the wrong nuts, which would be bad”.
However, as Dr. Lisa Mosconi lays out for us, there’s a lot more than that!
This book is as much a treatise of brain health in the context of nutrition, as it is a “eat this and avoid that” guide.
Which is good, because our brains don’t exist in isolation, and nor do the nutrients that we consume. Put it this way:
We have a tendecy to think of our diets as a set of slider-bars, “ok, that’s 104% of my daily intake of fiber, I need another 10g protein and that’ll be at 100%, I’ve had 80% of the vitamin C that I need, and…”
Whereas in reality: much of what we eat interacts positively or negatively with other things, and thus needs to be kept in balance. And not only that, but other peri-nutritional factors play a big part too! From obvious things like hydration, to less obvious things like maintaining good gut microbiota, our brains rely on us to do a lot of things for them.
This book is very easy-reading, though a weakness is it doesn’t tend to summarise key ideas much, give cheat-sheets, that sort of thing. We recommend reading this book with a notebook to the side, to jot down things you want to attend to in your own dietary habits.
Bottom line: this is an excellent overview of brain health in the context of nutrition, and is more comprehensive than most “eat this for good brain health and avoid that” books.

The Sweet Truth About Diabetes
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.
There’s A Lot Of Confusion About Diabetes!
For those readers who are not diabetic, nor have a loved one who is diabetic, nor any other pressing reason to know these things, first a quick 101 rundown of some things to understand the rest of today’s main feature:
- Blood sugar levels: how much sugar is in the blood, measured in mg/dL or mmol/L
- Hyperglycemia or “hyper” for short: too much sugar in the blood
- Hypoglycemia or “hypo” for short: too little sugar in the blood
- Insulin: a hormone that acts as a gatekeeper to allow sugar to pass, or not pass, into various parts of the body
- Type 1 diabetes (sometimes capitalized, and/or abbreviated to “T1D”) is an autoimmune disorder that prevents the pancreas from being able to supply the body with insulin. This means that taking insulin consistently is necessary for life.
- Type 2 diabetes is a matter of insulin resistance. The pancreas produces plenty of insulin, but the body has become desensitized to it, so it doesn’t work properly. Taking extra insulin may sometimes be necessary, but for many people, it can be controlled by means of a careful diet and other lifestyle factors.
With that in mind, on to some very popular myths…
Diabetes is caused by having too much sugar
While sugar is not exactly a health food, it’s not the villain of this story either.
- Type 1 diabetes has a genetic basis, triggered by epigenetic factors unrelated to sugar.
- Type 2 diabetes comes from a cluster of risk factors which, together, can cause a person to go through pre-diabetes and acquire type 2 diabetes.
- Those risk factors include:
- A genetic predisposition
- A large waist circumference
- (this is more relevant than BMI or body fat percentage)
- High blood pressure
- A sedentary lifestyle
- Age (the risk starts rising at 35, rises sharply at 45, and continues upwards with increasing age)
- Those risk factors include:
Read more: Risk Factors for Type 2 Diabetes
Diabetics can’t have sugar
While it’s true that diabetics must be careful about sugar (and carbs in general), it’s not to say that they can’t have them… just: be mindful and intentional about it.
- Type 1 diabetics will need to carb-count in order to take the appropriate insulin bolus. Otherwise, too little insulin will result in hyperglycemia, or too much insulin will result in hypoglycemia.
- Type 2 diabetics will often be able to manage their blood sugar levels with diet alone, and slow-release carbs will make this easier.
In either case, having quick release sugars will increase blood sugar levels (what a surprise), and sometimes (such as when experiencing a hypo), that’s what’s needed.
Also, when it comes to sugar, a word on fruit:
Not all fruits are equal, and some fruits can help maintain stable blood sugar levels! Read all about it:
Fruit Intake to Prevent and Control Hypertension and Diabetes
Artificial sweeteners are must-haves for diabetics
Whereas sugar is a known quantity to the careful diabetic, some artificial sweeteners can impact insulin sensitivity, causing blood sugars to behave in unexpected ways. See for example:
The Impact of Artificial Sweeteners on Body Weight Control and Glucose Homeostasis
If a diabetic person is hyper, they should exercise to bring their blood sugar levels down
Be careful with this!
- In the case of type 2 diabetes, it may (or may not) help, as the extra sugar may be used up.
- Type 1 diabetes, however, has a crucial difference. Because the pancreas isn’t making insulin, a hyper (above a certain level, anyway) means more insulin is needed. Exercising could do more harm than good, as unlike in type 2 diabetes, the body has no way to use that extra sugar, without the insulin to facilitate it. Exercising will just pump the syrupy hyperglycemic blood around the body, potentially causing damage as it goes (all without actually being able to use it).
There are other ways this can be managed that are outside of the scope of this newsletter, but “be careful” is rarely a bad approach.

100,000 People, 30 Years, One Clear Winner vs Aging
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.
Generally speaking, the scientific community most highly lauds the Mediterranean diet as being best for general health:
The Mediterranean Diet: What Is It Good For? ← what isn’t it good for?!
However, even this can be tweaked with specific health considerations in mind, for example:
Four Ways To Upgrade The Mediterranean Diet ← these tweaks offer adjusted versions of the Mediterranean diet, optimized for anti-inflammation, gut health, heart health, or brain health
And today we present to you some very good research into…
The best diet for aging well
Let’s be clear on terms first: by “aging well”, this means reaching age 70 without chronic diseases and maintaining good cognitive, physical, and mental health.
105,015 participants (of whom, 66% women, average age 53 at the start of the study) were followed for up to 30 years. Not in the stalkery way, but in the longitudinal study way. We say “up to”, because as with any sizeable longitudinal study, some died before the end of the study.
9,771 of them were deemed, at the end of the study, to have achieved “healthy aging”.
So, how did those participants achieve that, in terms of diet?
The dietary patterns that had the strongest positive impact were:
- AHEI (Alternative Healthy Eating Index): best for mental and physical function, overall healthy aging.
- PHDI (Planetary Health Diet Index): best for cognitive health and survival to age 70.
- DASH (Dietary Approaches to Stop Hypertension): strongest general impact.
- MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay): best for brain health.
- rEDIH (Reversed Empirical Dietary Index for Hyperinsulinemia): most effective for chronic disease prevention.
In contrast:
- EIDP (Empirically Inflammatory Dietary Pattern): shocking nobody, performed least well in all areas
You are probably wondering what those dietary patterns actually consist of, so click here to see a chart of what’s included or excluded in each dietary pattern.
As you can see, the AHEI diet that was “best for mental and physical function, overall healthy aging” is essentially the Mediterranean diet with three small tweaks:
- no seafood, but long-chain omega-3 fatty acids include to compensate
- no sugar-sweetened beverages or fruit juices
- “no” sodium (in other words, minimal sodium, since almost everything contains trace amounts)
The PHDI diet, which was “best for cognitive health and survival to age 70” is essentially a whole-foods plant-based diet. Which in turn is very consistent with the Mediterranean, except that it excludes animal products, of which the Mediterranean diet uses small amounts.

A panel of 69 doctors and nutritionists examined the evidence for 38 diets (including Mediterranean, MIND, DASH, Vegan, Keto, Slimfast, WeightWatchers, Nutrisystem, and more) and scored them in 21 categories (e.g. best for general health, best for weight loss, best for heart, best against diabetes, etc):

Cottage cheese is back and all over TikTok. Two dietitians explain why social media’s obsessed
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.
You might remember cottage cheese from your childhood. Back then, it was considered “diet food”. You ate it out of the tub, with celery or spread it on crackers for a low-calorie snack. Then cottage cheese went out of fashion.
But cottage cheese is having a resurgence. In recent months, Google searches for “cottage cheese” have risen to the highest levels since 2004.
Social media influencers have been promoting its benefits on TikTok and Instagram with hashtags such as #cottagecheese, #cottagecheeseforlife, and #cottagecheeserecipe. Sales of cottage cheese around the world have skyrocketed.
Let’s see why cottage cheese is having such a moment.
Karolina Kaboompics/Pexels What is cottage cheese?
Cottage cheese is a fresh dairy cheese product with a mild flavour and a slightly tangy taste. It is made by curdling cow’s milk, then draining the whey, leaving behind the curds. These curds are usually small and lumpy, and the texture can vary from creamy to dry, depending on the amount of whey left in the cheese.
The term “cottage cheese” is said to have originated because the cheese was generally made in cottage-type houses from leftover milk, after making butter.
Cottage cheese is cheap, costing about A$12 per kilogram in the supermarket, similar to ricotta cheese.
It’s also surprisingly simple to make at home using freely available recipes. All you need is milk, salt and a splash of vinegar.
We’re using cottage cheese in new ways
It’s difficult to know what started the latest cottage cheese trend. But the creativity of social media means people are sharing alternative ways to use cottage cheese, changing people’s views from it being boring and lacking flavour to it being versatile and healthy.
People are spreading cottage cheese on toast and using it to make dishes such as porridge, dips, salads, bread and flatbreads. They’re using it in cakes and scones, and in desserts such as mousse and ice cream.
Is cottage cheese healthy?
Compared with other cheeses, cottage cheese is low in fat and therefore energy (kilojoules or kJ). This makes it a smart choice for people looking to cut down on their daily energy intake.
For example, 100 grams of cottage cheese contains about 556kJ. The same amount of cheddar contains 1,254kJ and parmesan 1,565kJ.
Many cheeses are rich in protein but they often contain higher amounts of kilojoules due to their fat content. But cottage cheese has substantial amounts of protein with fewer kilojoules.
This makes cottage cheese an ideal option for people aiming to maximise their protein intake without eating large amounts of kilojoules.
Some 100g of cottage cheese provides 17g protein. This is about the same found in three eggs, 60g chicken breast or 320 millilitres (about 300g) full-fat yoghurt.
People are sharing images of their cottage cheese creations on TikTok and Instagram. New Africa/Shutterstock Cottage cheese also contains high levels of vitamin B12 (important for healthy brain function), riboflavin (supports healthy skin and eyes), phosphorus (helps build strong bones and teeth) and folate (essential for cell growth).
However, cottage cheese is lower in calcium compared with other cheeses. It contains just 89 milligrams per 100g. This compares with parmesan (948mg), haloumi (620mg) and ricotta (170mg).
You’ve convinced me. How can I use cottage cheese?
Beyond its excellent nutrition profile, the resurgence of cottage cheese is enabling people to experiment in the kitchen. Its neutral flavour and varied textures – ranging from smooth to chunky – makes it suitable for a range of dishes, from sweet to savoury.
TikTok and Instagram have some great recipes. You could start with an old faithful recipe of celery and cottage cheese, and work your way towards new options such as cottage cheese ice cream.
The healthiest recipes will be those that combine cottage cheese with wholefoods such as fruits, vegetables, nuts and seeds, and lean protein sources.
For instance, you can make a cottage cheese wrap then fill it with vegetables and a lean source of protein (such as chicken or fish).
Other combinations include cottage cheese salad dressings, vegetable dips and egg salads.
Cottage cheese’s rise in popularity is well deserved. Including more cottage cheese in your diet is a smart choice for getting a high dose of protein without adding processed ingredients or too much energy. Embrace the trend and get creative in the kitchen.

‘Tis To Season To Be SAD-Savvy
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.
Seasonal Affective Disorder & SAD Lamps
For those of us in the Northern Hemisphere, it’s that time of the year; especially after the clocks recently went back and the nights themselves are getting longer. So, what to do in the season of 3pm darkness?
First: the problem
The problem is twofold:
- Our circadian rhythm gets confused
- We don’t make enough serotonin
The latter is because serotonin production is largely regulated by sunlight.
People tend to focus on item 2, but item 1 is important too—both as problem, and as means of remedy.
Circadian rhythm is about more than just light
We did a main feature on this a little while back, talking about:
- What light/dark does for us, and how it’s important, but not completely necessary
- How our body knows what time it is even in perpetual darkness
- The many peaks and troughs of many physiological functions over the course of a day/night
- What that means for us in terms of such things as diet and exercise
- Practical take-aways from the above
Read: The Circadian Rhythm: Far More Than Most People Know
With that in mind, the same methodology can be applied as part of treating Seasonal Affective Disorder.
Serotonin is also about more than just light
Our brain is a) an unbelievably powerful organ, and the greatest of any animal on the planet b) a wobbly wet mass that gets easily confused.
In the case of serotonin, we can have problems:
- knowing when to synthesize it or not
- synthesizing it
- using it
- knowing when to scrub it or not
- scrubbing it
- etc
Selective Serotonin Re-uptake Inhibitors (SSRIs) are a class of antidepressants that, as the name suggests, inhibit the re-uptake (scrubbing) of serotonin. So, they won’t add more serotonin to your brain, but they’ll cause your brain to get more mileage out of the serotonin that’s there, using it for longer.
So, whether or not they help will depend on you and your brain:

How useful are artificial sunlight lamps?
Artificial sunlight lamps (also called SAD lamps), or blue light lamps, are used in an effort to “replace” daylight.
Does it work? According to the science, generally yes, though everyone would like more and better studies:
- The Efficacy of Light Therapy in the Treatment of Seasonal Affective Disorder: A Meta-Analysis of Randomized Controlled Trials
- Blue-Light Therapy for Seasonal and Non-Seasonal Depression: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Interestingly, it does still work in cases of visual impairment and blindness:
How much artificial sunlight is needed?
According to Wirz-Justice and Terman (2022), the best parameters are:
- 10,000 lux
- full spectrum (white light)
- 30–60 minutes exposure
- in the morning

5 Ways to Beat Menopausal Weight Gain!

As it turns out, “common” does not mean “inevitable”!
Health Coach Kait’s advice
Her 5 tips are…
- Understand your metabolism: otherwise you’re working the dark and will get random results. Learn about how different foods affect your metabolism, and note that hormonal changes due to menopause can mean that some food types have different effects now.
- Eat enough protein: one thing doesn’t change—protein helps with satiety, thus helping to avoid overeating.
- Focus on sleep: prioritizing sleep is essential for hormone regulation, and that means not just sex hormones, but also food-related hormones such as insulin, ghrelin, and leptin.
- Be smart about carbs: taking a lot of carbs at once can lead to insulin spikes and thus metabolic disorder, which in turn leads to fat in places you don’t want it (especially your liver and belly). Enjoying a low-carb diet, and/or pairing your carbs with proteins and fats, does a lot to help avoid insulin spikes too. Not mentioned in the video, but we’re going to mention here: don’t underestimate fiber’s role either, especially if you take it before the carbs, which is best for blood sugars, as it gives a buffer to the digestive process, thus slowing down absorption of carbs.
- Build muscle: if trying to avoid/lose fat, it’s tempting to focus on cardio, but we generally can’t exercise our way out of having fat, whereas having more muscle increases the body’s metabolic base rate, burning fat just by existing. So for this reason, enjoy muscle-building resistance exercises at least a few times per week.

Peaches vs Plums – 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 peaches to plums, we picked the peaches.
Why?
Both are great! But there is a clear winner out of these two botanically-similar fruits:
In terms of macronutrients they are very similar. Peaches have slightly more protein and plums have slightly more carbs, but the numbers are close enough to make no meaningful difference; they’re both mostly water.
They’re also not too far from each other in the category of vitamins; peaches have more of vitamins B2, B3, B5, E, and choline, while plums have more of vitamins B1, B6, B9, C, and K. They’re equal on vitamin A, by the way, and the vitamins they do differ in, differ by around the same margins, so this category is a clear tie.
When it comes to minerals, however, peaches win easily with more copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. The two fruits are equal on calcium, and plum is not higher in any minerals.
While they already won easily because of the mineral situation, it should be noted that peaches also have the lower glycemic index. But honestly, plums are fine too; peaches are just even lower.
So: enjoy both, but if you’re going to pick one, peaches boast the most!
