How To Actually Use Those Indices
Carbohydrates are essential for our life, and/but often bring about our early demise. It would be a very conveniently simple world if it were simply a matter of “enjoy in moderation”, but the truth is, it’s not that simple.
To take an extreme example, for the sake of clearest illustration: The person who eats an 80% whole fruit diet (and makes up the necessary protein and fats etc in the other 20%) will probably be healthier than the person who eats a “standard American diet”, despite not practising moderation in their fruit-eating activities. The “standard American diet” has many faults, and one of those faults is how it promotes sporadic insulin spikes leading to metabolic disease.
If your breakfast is a glass of orange juice, this is a supremely “moderate” consumption, but an insulin spike is an insulin spike.
Quick sidenote: if you’re wondering why eating immoderate amounts of fruit is unlikely to cause such spikes, but a single glass of orange juice is, check out:
Which Sugars Are Healthier, And Which Are Just The Same?
Glycemic Index
The first tool in our toolbox here is glycemic index, or GI.
GI measures how much a carb-containing food raises blood glucose levels, also called blood sugar levels, but it’s just glucose that’s actually measured, bearing in mind that more complex carbs will generally get broken down to glucose.
Pure glucose has a GI of 100, and other foods are ranked from 0 to 100 based on how they compare.
Sometimes, what we do to foods changes its GI.
- Some is because it changed form, like the above example of whole fruit (low GI) vs fruit juice (high GI).
- Some is because of more “industrial” refinement processes, such as whole grain wheat (medium GI) vs white flour and white flour products (high GI)
- Some is because of other changes, like starches that were allowed to cool before being reheated (or eaten cold).
Broadly speaking, a daily average GI of 45 is considered great.
But that’s not the whole story…
Glycemic Load
Glycemic Load, or GL, takes the GI and says “ok, but how much of it was there?”, because this is often relevant information.
Refined sugar may have a high GI, but half a teaspoon of sugar in your coffee isn’t going to move your blood sugar levels as much as a glass of Coke, say—the latter simply has more sugar in, and just the same zero fiber.
GL is calculated by (grams of carbs / 100) x GI, by the way.
But it still misses some important things, so now let’s look at…
Insulin Index
Insulin Index, which does not get an abbreviation (probably because of the potentially confusing appearance of “II”), measures the rise in insulin levels, regardless of glucose levels.
This is important, because a lot of insulin response is independent of blood glucose:
- Some is because of other sugars, some some is in response to fats, and yes, even proteins.
- Some is a function of metabolic base rate.
- Some is a stress response.
- Some remains a mystery!
Another reason it’s important is that insulin drives weight gain and metabolic disorders far more than glucose.
Note: the indices of foods are calculated based on average non-diabetic response. If for example you have Type 1 Diabetes, then when you take a certain food, your rise in insulin is going to be whatever insulin you then take, because your body’s insulin response is disrupted by being too busy fighting a civil war in your pancreas.
If your diabetes is type 2, or you are prediabetic, then a lot of different things could happen depending on the stage and state of your diabetes, but the insulin index is still a very good thing to be aware of, because you want to resensitize your body to insulin, which means (barring any urgent actions for immediate management of hyper- or hypoglycemia, obviously) you want to eat foods with a low insulin index where possible.
Great! What foods have a low insulin index?
Many factors affect insulin index, but to speak in general terms:
- Whole plant foods are usually top-tier options
- Lean and/or white meats generally have lower insulin index than red and/or fatty ones
- Unprocessed is generally lower than processed
- The more solid a food is, generally the lower its insulin index compared to a less solid version of the same food (e.g. baked potatoes vs mashed potatoes; cheese vs milk, etc)
But do remember the non-food factors too! This means where possible:
- reducing/managing stress
- getting frequent exercise
- getting good sleep
- practising intermittent fasting

The Blue Zones, Second Edition – by Dan Buettner
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.
Eat beans & greens, take walks, have a purpose; you can probably list off the top of your head some of the “advices from Blue Zones”, so what makes this book stand out?
This is perhaps one of the most thoughtful investigations; the author (a National Geographic researcher) toured and researched all the Blue Zones, took many many notes (we get details), and asked a lot of questions that others skipped.
For example, a lot of books about the Blue Zones mention the importance of community—but they don’t go into much detail of what that looks like… And they certainly don’t tend to explain what we should do about it.
And that’s because community is often viewed as environmental in a way that we can’t control. If we want to take supplements, eat a certain way, exercise, etc, we can do all those things alone if we want. But if we want community? We’re reliant on other people—and that’s a taboo in the US, and US-influenced places.
So, one way this book excels is in describing how exactly people foster community in the Blue Zones (hint: the big picture—the form of the community—is different in each place, but the individual actions taken are similar), with particular attention to the roles actively taken on by the community elders.
In a similar vein, “reduce stress” is good, but what mindsets and mechanisms do they use that are still reproducible if we are not, for example, Okinawan farmers? Again, Buettner delivers in spades.
Bottom line: this is the Blue Zones book that digs deeper than others, and makes the advices much more applicable no matter where we live.

Hanging Exercises For Complete Beginners & Older Adults
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.
Hanging (not the kind with a gallows) is great for the heath, improving not just strength and mobility, but also—critically—looking after spinal health too. Amanda Raynor explains in this video how this exercise is accessible to anyone (unless you have no arms, in which case, sorry, this one is just not for you—though hanging by your legs will also give similar spinal benefits!).
Hanging out
Hanging can be done at home or at a park, with minimal equipment (a bar, a sturdy tree branch, etc).
Note: the greater the diameter of the bar, the more it will work your grip strength, and/but the harder it will be. So, it’s recommend to start with a narrow-diameter bar first.
Getting started:
- Start with a “dead hang”: grip the bar with hands shoulder-width apart, thumb wrapped around.
- Aim to hang without pulling up; build endurance gradually (10–30 seconds is fine at first).
- Work up to holding for 60 seconds in three sets as a fitness goal.
Progression:
- If unable to hang at all initially, use a chair or stool to support some body weight.
- Gradually reduce foot support to increase duration of free hanging.
- Start with 10 seconds, progressing by small increments (e.g: 15, 20, 25 seconds) until reaching 60 seconds.
Advanced variations:
- Move the body while hanging (e.g., circles, knee lifts).
- Experiment with different grips (overhand, underhand) for varied muscle engagement.
- Try scapular pulls or one-arm hangs for additional challenge and strength-building.

Simple Wall Pilates for Seniors – by Grace Clark
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.
While the cover illustration makes this look a little too simple, in fact there’s a lot of value in this book, with exercises ranging from things like that on the cover, to the “wall downward dog”. But the actual exercises (of which there are 29) themselves are only a part of the book (taking about 70 pages of it with clear illustrations).
There’s also a lot about important Pilates principles to apply, such as breathing, correct body alignment (if you don’t already do Pilates, you will not have this, as Pilates alignment is quite specific), flexibility, balance, stability, coordination, range of motion, isometric exercise considerations, endurance, and more.
Unlike a lot of “…for seniors” books, this is not a watered down barely-does-anything version of the “real” exercises, but rather, would present most the same challenges to a 20-year-old reader; it’s just that the focus here is more on matters that tend to concern an older rather than younger demographic. That 20-something may be busy building their butt, for instance, while the 80-year-old is building their bones. No reason both shouldn’t do both, of course, but the focus is age-specific.
The author guides us through working up from easy things to hard, breaking stuff down so that we can progress at our own pace, such that even the most cautious or enthusiastic reader can start at an appropriate point and proceed accordingly.
She also talks us through a 28-day program (as promised by the subtitle), and advice on how to keep it going without plateauing, how to set realistic goals, how to tailor it to our abilities as we go, track our progress, and so forth.
The style is clear and instructional, and one thing that sets this apart from a lot of Pilates books is that the education comes from an angle not of “trust me”, but rather from well-sourced claims with bibliography whose list spans 5 pages at the end.
Bottom line: if you’d like to progressively increase your strength, stability, and more—with no gym equipment, just a wall—then this book will have you see improvements in the 28 days it promises, and thereafter.

Parsley vs Spinach – 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 parsley to spinach, we picked the parsley.
Why?
First of all, writer’s anecdote: today’s choice brought to you by a real decision here in my household! You see, a certain dish I sometimes prepare (it’s just a wrap-based dish, nothing fancy) requires a greenery component, and historically I’ve used kale or spinach. Of those two, I prefer kale while my son, who lives (and dines) with me, prefers spinach. However, we both like parsley equally, so I’m going to use that today. But I was curious about how it performed nutritionally, hence today’s comparison!
Ok, now for the stats…
In terms of macros, the only difference is that parsley has more fiber and carbs, for an approximately equal glycemic index, so we’ll go with the one with the highest total fiber, which is parsley.
In the category of vitamins, parsley has more of vitamins B3, B5, B7, B9, C, and K, while spinach has more of vitamins A, B2, B6, E, and choline. So, a marginal 6:5 win for parsley (and in the margins of difference are also in parsley’s favor, for example parsley has 13x the vitamin C, and 2x or 3x the other vitamins it won with, while spinach boasts 2x for some vitamins, and only 1.2x or 1.5x the others).
When it comes to minerals, parsley has more iron, phosphorus, potassium, and zinc, while spinach has more copper, magnesium, manganese, and selenium. So, a 4:4 tie on these.
In terms of phytochemicals, parsley has a much higher polyphenol content (that’s good) while spinach has a much higher oxalate content (that’s neutral for most people, but bad if you have certain kidney problems). So, another win for parsley.
Adding up the sections makes a clear overall win for parsley, but by all means enjoy either or both, unless you are avoiding oxalates, in which case, the oxalates in spinach can be reduced by cooking, but honestly, for most dishes you might as well just pick a different greens option (like parsley, or collard greens if you want something closer to the culinary experience of eating spinach).

Antioxidant Matcha Snack Bars
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 antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.
You will need
For the base:
- ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
- ⅔ cup chopped dates
For the main part:
- 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
- ½ cup almond milk (or your preferred milk of any kind)
- ½ cup cacao nibs
- 2 tbsp lime juice
- 1 tbsp matcha powder
- 1 tbsp maple syrup (omit if you don’t care for sweetness)
For the topping (optional):
- 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
- Spare cacao nibs, chopped nuts, or anything else you might want on there
Method
(we suggest you read everything at least once before doing anything)
1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.
2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.
3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.
4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.
5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.
6) Serve!
Enjoy!

“You Just Need to Lose Weight” And 19 Other Myths About Fat People – by Aubrey Gordon
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’ve previously reviewed another book by this author, “What We Don’t Talk About When We Talk About Fat”, and this time, she’s doing some important mythbusting.
The titular “you just need to lose weight” is a commonly-taken easy-out for many doctors, to avoid having to dispense actual treatment for an actual condition. Whether or not weight loss would help in a given situation is often immaterial; “kicking the can down the road” is the goal.
Most of the book is divided into 20 chapters, each of them devoted to debunking one myth. Think of it like 10almonds’ “Mythbusting Friday” edition (indeed, we did one about obesity), but with an entire book, and as much room as she needs to provide much more detail than we can ever get into in a single article.
And far from being a mere polemic, she does indeed provide that detail—this is clearly a very well-researched book, above and beyond the author’s own personal experience. Further, all the key points are illustrated and articulated clearly, making the book’s ideas very comprehensible.
The style is pop-science, but with frequent bibliographical references for relevant sources.
Bottom line: for some readers, this book will come as a great validation; for others, it may be eye-opening. Either way, it’s a very worthwhile read.
