Glycemic Index vs Glycemic Load vs Insulin Index

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

  • Glutathione: More Than An Antioxidant

    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.

    Glutathione’s Benefits: The Usual And The Unique

    Glutathione is a powerful antioxidant that does all the things we might reasonably expect an antioxidant to do, plus some beneficial quirks of its own.

    We do make glutathione in our bodies, but we can also get it from our diet, and of course, we can also supplement it.

    What foods is it in?

    It’s in a lot of foods, but some top examples include:

    • turmeric
    • avocado
    • asparagus
    • almonds
    • cruciferous vegetables
    • watermelon
    • garlic

    For a fuller list and discussion, see:

    Glutathione for Food and Health Applications with Emphasis on Extraction, Identification, and Quantification Methods: A Review

    What does it do?

    Let’s start with the obvious; as with most things that are antioxidant, it is also anti-inflammatory. Increasing or decreasing glutathione levels is associated with decreased or increased inflammation, respectively. For example:

    Glutathione S-transferase theta 1 protects against colitis through goblet cell differentiation via interleukin-22

    It being anti-inflammatory also means it can be beneficial in calming autoimmune disorders:

    Glutathione: a key player in autoimmunity

    And to complete the triad of “those three things that generally go together”, yes, this means it also has anticancer potential, but watch out!

    ❝Although in healthy cells [glutathione] is crucial for the removal and detoxification of carcinogens, elevated [glutathione] levels in tumor cells are associated with tumor progression and increased resistance to chemotherapeutic drugs❞

    ~ Dr. Miroslava Cuperlovic-Culf et al.

    Read in full: Role of Glutathione in Cancer: From Mechanisms to Therapies

    So in other words, when it comes to cancer risk management, glutathione is a great preventative, but the opposite of a cure.

    What were those “beneficial quirks of its own”?

    They are mainly twofold, and the first is that it improves insulin sensitivity. There are many studies showing this, but here’s a recent one from earlier this year:

    The Role of Glutathione and Its Precursors in Type 2 Diabetes

    The other main “beneficial quirk of its own” is that it helps prevent and/or reverse non-alcoholic fatty liver disease, as in this study from last year:

    Glutathione: Pharmacological aspects and implications for clinical use in non-alcoholic fatty liver disease

    Because of glutathione’s presence in nuts, fruits, and vegetables, this makes it a great thing to work in tandem with a dietary approach to preventing/reversing NAFLD, by the way:

    How To Unfatty A Fatty Liver

    Anything else?

    It’s being investigated as a potential treatment for Parkinson’s disease symptoms, but the science is young for this one, so there is no definitive recommendation yet in this case. If you’re interested in that, though, do check out the current state of the science at:

    Potential use of glutathione as a treatment for Parkinson’s disease

    Is it safe?

    While there is no 100% blanket statement of safety that can ever be made about anything (even water can kill people, and oxygen ultimately kills everyone that something else doesn’t get first), glutathione has one of the safest general safety profiles possible, with the exception we noted earlier (if you have cancer, it is probably better to skip this one unless an oncologist or similar advises you otherwise).

    As ever, do speak with your doctor/pharmacist to be sure in any case, though!

  • Why Zebras Don’t Get Ulcers – by Dr. Robert M. Sapolsky

    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 book does kick off with a section that didn’t age well—he talks of the stress induced globally by the Spanish Flu pandemic of 1918, and how that kind of thing just doesn’t happen any more. Today, we have much less existentially dangerous stressors!

    However, the fact we went and had another pandemic really only adds weight to the general arguments of the book, rather than detracting.

    We are consistently beset by “the slings and arrows of outrageous fortune” as Shakespeare would put it, and there’s a reason (or twenty) why many people go grocery-shopping with the cortisol levels of someone being hunted for sport.

    So, why don’t zebras get ulcers, as they actually are hunted for food?

    They don’t have rent to pay or a mortgage, they don’t have taxes, or traffic, or a broken washing machine, or a project due in the morning. Their problems come one at a time. They have a useful stress response to a stressful situation (say, being chased by lions), and when the danger is over, they go back to grazing. They have time to recover.

    For us, we are (usually) not being chased by lions. But we have everything else, constantly, around the clock. So, how to fix that?

    Dr. Sapolsky comprehensively describes our physiological responses to stress in quite different terms than many. By reframing stress responses as part of the homeostatic system—trying to get the body back into balance—we find a solution, or rather: ways to help our bodies recover.

    The style is “pop-science” and is very accessible for the lay reader while still clearly coming from a top-level academic who is neck-deep in neuroendocrinological research. Best of both worlds!

    Bottom line: if you try to take very day at a time, but sometimes several days gang up on you at once, and you’d like to learn more about what happens inside you as a result and how to fix that, this book is for you!

  • What’s the difference between autism and Asperger’s disorder?

    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.

    Swedish climate activist Greta Thunberg describes herself as having Asperger’s while others on the autism spectrum, such as Australian comedian Hannah Gatsby, describe themselves as “autistic”. But what’s the difference?

    Today, the previous diagnoses of “Asperger’s disorder” and “autistic disorder” both fall within the diagnosis of autism spectrum disorder, or ASD.

    Autism describes a “neurotype” – a person’s thinking and information-processing style. Autism is one of the forms of diversity in human thinking, which comes with strengths and challenges.

    When these challenges become overwhelming and impact how a person learns, plays, works or socialises, a diagnosis of autism spectrum disorder is made.

    Where do the definitions come from?

    The Diagnostic and Statistical Manual of Mental Disorders (DSM) outlines the criteria clinicians use to diagnose mental illnesses and behavioural disorders.

    Between 1994 and 2013, autistic disorder and Asperger’s disorder were the two primary diagnoses related to autism in the fourth edition of the manual, the DSM-4.

    In 2013, the DSM-5 collapsed both diagnoses into one autism spectrum disorder.

    How did we used to think about autism?

    The two thinkers behind the DSM-4 diagnostic categories were Baltimore psychiatrist Leo Kanner and Viennese paediatrician Hans Asperger. They described the challenges faced by people who were later diagnosed with autistic disorder and Asperger’s disorder.

    Kanner and Asperger observed patterns of behaviour that differed to typical thinkers in the domains of communication, social interaction and flexibility of behaviour and thinking. The variance was associated with challenges in adaptation and distress.

    Between the 1940s and 1994, the majority of those diagnosed with autism also had an intellectual disability. Clinicians became focused on the accompanying intellectual disability as a necessary part of autism.

    The introduction of Asperger’s disorder shifted this focus and acknowledged the diversity in autism. In the DSM-4 it superficially looked like autistic disorder and Asperger’s disorder were different things, with the Asperger’s criteria stating there could be no intellectual disability or delay in the development of speech.

    Today, as a legacy of the recognition of the autism itself, the majority of people diagnosed with autism spectrum disorder – the new term from the DSM-5 – don’t a have an accompanying intellectual disability.

    What changed with ‘autism spectrum disorder’?

    The move to autism spectrum disorder brought the previously diagnosed autistic disorder and Asperger’s disorder under the one new diagnostic umbrella term.

    It made clear that other diagnostic groups – such as intellectual disability – can co-exist with autism, but are separate things.

    The other major change was acknowledging communication and social skills are intimately linked and not separable. Rather than separating “impaired communication” and “impaired social skills”, the diagnostic criteria changed to “impaired social communication”.

    The introduction of the spectrum in the diagnostic term further clarified that people have varied capabilities in the flexibility of their thinking, behaviour and social communication – and this can change in response to the context the person is in.

    Why do some people prefer the old terminology?

    Some people feel the clinical label of Asperger’s allowed a much more refined understanding of autism. This included recognising the achievements and great societal contributions of people with known or presumed autism.

    The contraction “Aspie” played an enormous part in the shift to positive identity formation. In the time up to the release of the DSM-5, Tony Attwood and Carol Gray, two well known thinkers in the area of autism, highlighted the strengths associated with “being Aspie” as something to be proud of. But they also raised awareness of the challenges.

    What about identity-based language?

    A more recent shift in language has been the reclamation of what was once viewed as a slur – “autistic”. This was a shift from person-first language to identity-based language, from “person with autism spectrum disorder” to “autistic”.

    The neurodiversity rights movement describes its aim to push back against a breach of human rights resulting from the wish to cure, or fundamentally change, people with autism.

    The movement uses a “social model of disability”. This views disability as arising from societies’ response to individuals and the failure to adjust to enable full participation. The inherent challenges in autism are seen as only a problem if not accommodated through reasonable adjustments.

    However the social model contrasts itself against a very outdated medical or clinical model.

    Current clinical thinking and practice focuses on targeted supports to reduce distress, promote thriving and enable optimum individual participation in school, work, community and social activities. It doesn’t aim to cure or fundamentally change people with autism.

    A diagnosis of autism spectrum disorder signals there are challenges beyond what will be solved by adjustments alone; individual supports are also needed. So it’s important to combine the best of the social model and contemporary clinical model.The Conversation

  • Celeriac vs Celery – Which is Healthier?

    Our Verdict

    When comparing celeriac to celery, we picked the celeriac.

    Why?

    Yes, these are essentially the same plant, but there are important nutritional differences:

    In terms of macros, celeriac has more than 2x the protein, and slightly more carbs and fiber. Both are very low glycemic index, so the higher protein and fiber makes celeriac the winner in this category.

    In the category of vitamins, celeriac has more of vitamins B1, B3, B5, B6, C, E, K, and choline, while celery has more of vitamins A and B9. An easy win for celeriac.

    When it comes to minerals, celeriac has more copper, calcium, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while celery is not higher in any minerals. Another obvious win for celeriac.

    Adding these sections up makes for a clear overall win for celeriac, but by all means enjoy either or both!

  • Hack Your Hunger

    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.

    When it comes to dealing with hunger, a common-sense way of dealing with it is “eat something”. However, many people find that they then eat the wrong things, in the wrong quantities, and end up in a cycle of overeating and being hungry.

    If this gets to the extreme, it can turn into a full-blown eating disorder:

    Eating Disorders: More Varied (And Prevalent) Than People Think

    …and even in more moderate presentations, the cycle of hunger and overeating is not great for the health. So, how to avoid that?

    Listen to your body (but: actually listen)

    Your body says: we’re running a little low on glycogen reserves so our energy’s going to start suffering in a few hours if we don’t eat some fruit, kill something and eat its fatty organs, or perhaps find some oily nuts.

    You hear: eat something bright and sugary, shout at the dog, eat some fried food, got it!

    Your body says: our water balance is a little off, we could do with some sodium, potassium, and perhaps some phosphorus to correct it.

    You hear: eat something salty, got it, potato chips coming right up!

    …and so on. Now, we know 10almonds readers are quite a health-conscious readership, so perhaps your responses are not quite like that. But the take-away point is still important: we need to listen to the whole message, and give the body what it actually needs, not what will just shut the message off the most quickly.

    Here’s how: Intuitive Eating Might Not Be What You Think

    Bonus: Interoception: Improving Our Awareness Of Body Cues

    About those cravings…

    As illustrated a little above, a lot of cravings might not be what they first appear, and in evolutionary terms, our body is centuries behind industrialization, in terms of adaptations, which means that even if we try to take the above into account, our responses can sometimes be inappropriate in the age of supermarkets.

    Natural appetite suppressants

    Eating more is not always the answer, not even if it’s more healthy food. And hunger pangs can be especially inconvenient if, for example, we are fasting at present, which is by the way a very healthful thing for most people:

    Learn more: Intermittent Fasting: What’s the truth?

    One way to suppress hunger is simply to trigger the stomach into sending “full” signals, which involves filling it. Since you do not want to overeat, the trick here is imply to use high-volume food.

    Consider for example: 30 grapes and 30 raisins have approximately the same calorie count (what with raisins being dried grapes, and the calories didn’t evaporate), but the bowl of fresh fruit is going to physically fill your stomach a lot more quickly than the tiny amount of dried fruit.

    More on this: Some Surprising Truths About Hunger And Satiety

    Protein is of course also an appetite suppressant, but it takes about 20 minutes for the signal to kick in. So a “hack” here is to snack on something proteinous at least 15 minutes before your main meal (for example, a portion of nuts while cooking, unless you’re allergic, or some dried fish unless you’re vegetarian/vegan; you get it, pick something high in protein and good for snacking, and have a small portion before your main meal).

    Nor is protein the only option!

    Scale it down

    Related to the above, there is a feedback loop that occurs here. The more you eat, the more your stomach slowly grows to accommodate it; the less you eat, the more your stomach slowly shrinks because the body tries hard to be an efficient organism, and will not maintain something that isn’t being used.

    So, there’s a bit of a catch-22; sate your hunger by filling your stomach with high volume foods, but filling it will cause it to grow?

    The trick is: do the “eat until 80% full” thing. That’s full enough that you have had a nice meal and are not suffering, without stretching the stomach.

    Enjoy your food

    Seriously! Actually enjoy it. Which means paying full attention to it. Eating can and should be a wonderful experience, so it’s best savored rather than inhaling a bowl of something in 30 seconds.

    Have you seen those dog bowls that have obstructions to slow down how quickly a dog eats? We can leverage that kind of trick too! While you might not want to eat from a dog bowl, how about having a little bowl of pistachio nuts rather than ready-to-eat peanuts? Or any shelled nuts that we must shell as we go. If you’re allergic to nuts, there are plenty of other foods with a high work-to-food ratio. Take some time and enjoy that pomegranate, for instance!

    Not that we necessarily have to make things difficult for ourselves either; we can just take appropriate care to ensure a good dining experience. Life is for living, so why not enjoy it?

  • How To Stay Alive (When You Really Don’t Want To)

    How To Stay Alive (When You Really Don’t Want To)

    A subscriber recently requested:

    ❝Request: more people need to be aware of suicidal tendencies and what they can do to ward them off❞

    …and we said we’d do that one of these Psychology Sundays, so here we are, doing it!

    First of all, we’ll mention that we did previously do a main feature on managing depression (in oneself or a loved one); here it is:

    The Mental Health First Aid That You’ll Hopefully Never Need

    Now, not all depression leads to suicidality, and not all suicide is pre-empted by depression, but there’s a large enough crossover that it seems sensible to put that article here, for anyone who might find it of use, or even just of interest.

    Now, onwards, to the specific, and very important, topic of suicide.

    This should go without saying, but some of today’s content may be a little heavy.

    We invite you to read it anyway if you’re able, because it’s important stuff that we all should know, and not talking about it is part of what allows it to kill people.

    So, let’s take a deep breath, and read on…

    The risk factors

    Top risk factors for suicide include:

    • Not talking about it
    • Having access to a firearm
    • Having a plan of specifically how to commit suicide
    • A lack of social support
    • Being male
    • Being over 40

    Now, some of these are interesting sociologically, but aren’t very useful practically; what a convenient world it’d be if we could all simply choose to be under 40, for instance.

    Some serve as alarm bells, such as “having a plan of specifically how to commit suicide”.

    If someone has a plan, that plan’s never going to disappear entirely, even if it’s set aside!

    (this writer is deeply aware of the specifics of how she has wanted to end things before, and has used the advice she gives in this article herself numerous times. So far so good, still alive to write about it!)

    Specific advices, therefore, include:

    Talk about it / Listen

    Depending on whether it’s you or someone else at risk:

    • Talk about it, if it’s you
    • Listen attentively, if it’s someone else

    There are two main objections that you might have at this point, so let’s look at those:

    “I have nobody to talk to”—it can certainly feel that way, sometimes, but you may be surprised who would listen if you gave them the chance. If you really can’t trust anyone around you, there are of course suicide hotlines (usually per area, so we’ll not try to list them here; a quick Internet search will get you what you need).

    If you’re worried it’ll result in bad legal/social consequences, check their confidentiality policy first:

    • Some hotlines can and will call the police, for instance.
    • Others deliberately have a set-up whereby they couldn’t even trace the call if they wanted to.
      • On the one hand, that means they can’t intervene
      • On the other hand, that means they’re a resource for anyone who will only trust a listener who can’t intervene.

    “But it is just a cry for help”—then that person deserves help. What some may call “attention-seeking” is, in effect, care-seeking. Listen, without judgement.

    Remove access to firearms, if applicable and possible

    Ideally, get rid of them (safely and responsibly, please).

    If you can’t bring yourself to do that, make them as inconvenient to get at as possible. Stored securely at your local gun club is better than at home, for example.

    If your/their plan isn’t firearm-related, but the thing in question can be similarly removed, remove it. You/they do not need that stockpile of pills, for instance.

    And of course you/they could get more, but the point is to make it less frictionless. The more necessary stopping points between thinking “I should just kill myself” and being able to actually do it, the better.

    Have/give social support

    What do the following people have in common?

    • A bullied teenager
    • A divorced 40-something who just lost a job
    • A lonely 70-something with no surviving family, and friends that are hard to visit

    Often, at least, the answer is: the absence of a good social support network

    So, it’s good to get one, and be part of some sort of community that’s meaningful to us. That could look different to a lot of people, for example:

    • A church, or other religious community, if we be religious
    • The LGBT+ community, or even just a part of it, if that fits for us
    • Any mutual-support oriented, we-have-this-shared-experience community, could be anything from AA to the VA.

    Some bonus ideas…

    If you can’t live for love, living for spite might suffice. Outlive your enemies; don’t give them the satisfaction.

    If you’re going to do it anyway, you might as well take the time to do some “bucket list” items first. After all, what do you have to lose? Feel free to add further bucket list items as they occur to you, of course. Because, why not? Before you know it, you’ve postponed your way into a rich and fulfilling life.

    Finally, some gems from Matt Haig’s “The Comfort Book”:
    • “The hardest question I have been asked is: “How do I stay alive for other people if I have no one?” The answer is that you stay alive for other versions of you. For the people you will meet, yes, but also the people you will be.”
    • “Stay for the person you will become”
    • “You are more than a bad day, or week, or month, or year, or even decade”
    • “It is better to let people down than to blow yourself up”
    • “Nothing is stronger than a small hope that doesn’t give up”
    • “You are here. And that is enough.”

    You can find Matt Haig’s excellent “The Comfort Book” on Amazon, as well as his more well-known book more specifically on the topic we’ve covered today, “Reasons To Stay Alive“.
