Our Verdict

When comparing kiwi to grapefruit, we picked the kiwi.

Why?

In terms of macros, kiwi has nearly 2x the protein, slightly more carbs, and 2x the fiber; both fruits are low glycemic index foods, however.

When it comes to vitamins, kiwi has more of vitamins B3, B6, B7, B9, C, E, K, and choline, while grapefruit has more of vitamins A, B1, B2, and B5. An easy win for kiwi.

In the category of minerals, kiwi is higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while grapefruit is not higher in any minerals. So, no surprises for guessing which wins this category.

One thing that grapefruit is a rich source of: furanocoumarin, which can inhibit cytochrome P-450 3A4 isoenzyme and P-glycoptrotein transporters in the intestine and liver—slowing down their drug metabolism capabilities, thus effectively increasing the bioavailability of many drugs manifold.

This may sound superficially like a good thing (improving bioavailability of things we want), but in practice it means that in the case of many drugs, if you take them with (or near in time to) grapefruit or grapefruit juice, then congratulations, you just took an overdose. This happens with a lot of meds for blood pressure, cholesterol (including statins), calcium channel-blockers, anti-depressants, benzo-family drugs, beta-blockers, and more. Oh, and Viagra, too. Which latter might sound funny, but remember, Viagra’s mechanism of action is blood pressure modulation, and that is not something you want to mess around with unduly. So, do check with your pharmacist to know if you’re on any meds that would be affected by grapefruit or grapefruit juice!

All in all, adding up the categories makes for an overwhelming total win for kiwis.

    (and it’s mostly not about reading/writing!)

    More than just shuffled letters

    This video provides a self-test based on the Bangor Dyslexia Test (BDT). The BDT is 94% accurate in identifying dyslexia, and it includes 9 parts, with a mix of questions and tasks. Answering “yes” or struggling with tasks indicates possible dyslexia. Collecting 4+ indicators suggests dyslexia, but of course is not a replacement for official diagnosis.

    It’s best to watch the video if you can, but here’s what to expect:

    1. Left-Right confusion: point your left hand to your right/left shoulder.
    2. Family history: any family members with dyslexia or struggles with reading/writing?
    3. Repeating numbers (order): repeat a given sequence of numbers in order.
    4. Letter confusion (e.g. b/d): do you confuse letters like “b” and “d” beyond age 8?
    5. Times tables: recite the 6, 7, and 8 times tables.
    6. Word manipulation: replace the letters in a word to create a new word, e.g. change “slide” (s ⇾ g) to “glide.”
    7. Repeating numbers (reversed): repeat a given sequence of numbers in reverse order.
    8. Months in reverse: recite the months of the year in reverse order.
    9. Subtraction: do you struggle with subtraction, e.g. 44-9 or 55-12?

    Writer’s anecdote: I am not dyslexic, and/but I have an impressive level of dyscalculia (the purely numerical equivalent), to the point I’ll sometimes use a calculator to do single-digit calculations, and I am so bad at calculating ages or other differences between dates (I will have to count on my fingers or else run the severe risk of out-by-one errors). I have also been known to make mistakes counting down from 10, which really ruins dramatic tension.

    In contrast, the left-right thing is interesting, because when I was first learning Arabic, I had no trouble reading/writing right-to-left, but I initially struggled so much to remember which way the “backspace” key would take me (in Arabic the backspace key backspaces to the right, despite still pointing to the left).

    Anyway, for the test itself, enjoy:

  • Parenting a perfectionist? Here’s how you can respond

    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.

    Some children show signs of perfectionism from early on. Young children might become frustrated and rip up their drawing if it’s not quite right. Older children might avoid or refuse to do homework because they’re afraid to make a mistake.

    Perfectionism can lead to children feeling overwhelmed, angry and frustrated, or sad and withdrawn.

    And yet perfectionism isn’t considered all bad in our society. Being called a “perfectionist” can be a compliment – code for being a great worker or student, someone who strives to do their best and makes sure all jobs are done well.

    These seemingly polarised views reflect the complex nature of perfectionism.

    What is perfectionism?

    Researchers often separate perfectionism into two parts:

    1. perfectionistic strivings: being determined to meet goals and achieve highly
    2. perfectionistic concerns: worry about being able to meet high standards, and self-criticism about performance.

    While perfectionistic strivings can be positive and lead to high achievement, perfectionistic concerns can lead to a higher chance of children developing eating disorders or anxiety and depression, and having lower academic achievement.

    Children and adolescents may experience perfectionism in relation to school work, sport, performance in art or music, or in relation to their own body.

    Signs of perfectionistic concerns in children and adolescents may include:

    A range of genetic, biological and environmental factors influence perfectionism in children. And as a parent, our role is important. While research evidence suggests we can’t successfully increase positive perfectionistic strivings in our children, harsh or controlling parenting can increase negative perfectionistic concerns in children.

    Parents who are perfectionistic themselves can also model this to their children.

    So, how can we walk the line between supporting our child’s interests and helping them to achieve their potential, without pressuring them and increasing the risk of negative outcomes?

    Give them space to grow

    A great metaphor is the gardener versus the carpenter described by psychology professor Alison Gopnik.

    Instead of trying to build and shape our children by controlling them and their environment (like a carpenter), parents can embrace the spirit of the gardener – providing lots of space for children to grow in their own direction, and nourishing them with love, respect and trust.

    We can’t control who they become, so it’s better to sit back, enjoy the ride, and look forward to watching the person they grow into.

    However, there is still plenty we can do as parents if our child is showing signs of perfectionism. We can role model to our children how to set realistic goals and be flexible when things change or go wrong, help our children manage stress and negative emotions, and create healthy balance in our family daily routine.

    Set realistic goals

    People with perfectionistic tendencies will often set unattainable goals. We can support the development of flexibility and realistic goal setting by asking curious questions, for example, “what would you need to do to get one small step closer to this goal?” Identifying upper and lower limits for goals is also helpful.

    If your child is fixed on a high score at school, for example, set that as the “upper limit” and then support them to identify a “lower limit” they would find acceptable, even if they are less happy with the outcome.

    This strategy may take time and practice to widen the gap between the two, but is useful to create flexibility over time.

    If a goal is performance-based and the outcome cannot be guaranteed (for example, a sporting competition), encourage your child to set a personal goal they have more control over.

    We can also have conversations about perfectionism from early on, and explain that everyone makes mistakes. In fact, it’s great to model this to our children – talking about our own mistakes and feelings, to show them that we ourselves are not perfect.

    Talk aloud practices can help children to see that we “walk the walk”. For example, if you burn dinner you could reflect:

    I’m disappointed because I put time and effort into that and it didn’t turn out as I expected. But we all make mistakes. I don’t get things right every time.

    Manage stress and negative emotions

    Some children and adolescents have a natural tendency towards perfectionism. Rather than trying to control their behaviour, we can provide gentle, loving support.

    When our child or adolescent becomes frustrated, angry, sad or overwhelmed, we support them best by helping them to name, express and validate all of their emotions.

    Parents may fear that acknowledging their child’s negative emotions will make the emotions worse, but the opposite is true.

    Creating healthy balance

    The building blocks of healthy child development are strong loving family relationships, good nutrition, creative play and plenty of physical activity, sleep and rest.

    Perfectionism is associated with rigidity, and thinking that there is only one correct way to succeed. We can instead encourage flexibility and creativity in children.

    Children’s brains grow through play. There is strong research evidence showing that creative, child-led play is associated with higher emotion regulation skills, and a range of cognitive skills, including problem-solving, memory, planning, flexibility and decision-making.

    Play isn’t just for young children either – there’s evidence that explorative, creative play of any kind also benefits adolescents and adults.

    There is also evidence that getting active outdoors in nature can promote children’s coping skills, emotion regulation and cognitive development.

  • Make Overnight Oats Shorter Or Longer For Different Benefits!

    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

    ❝How long do I have to soak oats for to get the benefits of “overnight oats”?❞

    The primary benefit of overnight oats (over cooked oats) is that they are soft enough to eat without having been cooked (as cooking increases their glycemic index).

    So, if it’s soft, it’s good to eat. A few hours should be sufficient.

    Bonus information

    If, by the way, you happen to leave oats and milk (be it animal or plant milk) sealed in a jar at room temperature for a 2–3 days (less if your “room temperature” is warmer than average), it will start to ferment.

    • Good news: fermentation can bring extra health benefits!
    • Bad news: you’re on your own if something pathogenic is present

    It’s easy to assume that anyone with an eating disorder can be easily recognized by the resultantly atypical body composition, but it’s often not so.

    Beyond the obvious

    We’ll not keep them a mystery; the 7 invisible eating disorders discussed by therapist Kati Morton in this video are:

    • OSFED (Other Specified Feeding or Eating Disorder): a catch-all diagnosis for those who don’t meet the criteria for more specific eating disorders but still have significant eating disorder behaviors.
    • Atypical Anorexia: characterized by all the symptoms of anorexia nervosa (especially: intense fear of gaining weight, and body image distortion) except that the individual’s weight remains in a normal range.
    • Atypical Bulimia: similar to bulimia nervosa, but the frequency or duration of binge-purge behaviors does not meet the usual diagnostic criteria and thus can fly under the radar.
    • Atypical Binge-Eating Disorder: has episodes of consuming large amounts of food without compensatory behaviors (e.g. purging), but the episodes are less frequent and/or intense than typical binge-eating disorder.
    • Purging Disorder: purging behaviors such as self-induced vomiting or laxative abuse without having binge-eating episodes (thus, this not being binging, and nothing obvious is happening outside of the bathroom).
    • Night Eating Syndrome: consuming excessive amounts of food during the night while being fully aware of the nature of the eating episodes, which disrupts sleep and leads to guilt.
    • Rumination Disorder: repeatedly regurgitating food, which may be rechewed, reswallowed, or spat out, without nausea or involuntary retching, often as a self-soothing mechanism.

  • Overcoming Gravity – by Steven Low

    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 author, a professional gymnast and coach with a background in the sciences, knows his stuff here. This is what it says on the tin: it’s rigorously systematic. It’s also the most science-based calisthenics book this reviewer has read to date.

    If you just wanted to know how to do some exercises, then this book would be very much overkill, but if you want to be able to go from no knowledge to expert knowledge, then the nearly 600 pages of this weighty tome will do that for you.

    This is a textbook, it’s a “the bible of…” style book, it’s the one that if you’re serious, will engage you thoroughly and enable you to craft the calisthenics-forged body you want, head to toe.

    As if it weren’t already overdelivering, it also has plenty of information on injury avoidance (or injury/condition management if you have some existing injury or chronic condition), and building routines in a dynamic fashion that avoids becoming a grind, because it’s going from strength to strength while cycling through different body parts.

    Bottom line: if you’d like to get serious about calisthenics, then this is the book for you.

  • Drug Metabolism (When You’re Not Average!)

    When Your Medications Run Out… Of You

    Everybody knows that alcohol can affect medications’ effects, but what of smoking, and what of obesity? And how does the alcohol thing work anyway?

    It’s all about the enzymes

    Medicines that are processed by the liver (which is: most medicines) are metabolized there by specialist enzymes, and the things we do can increase or decrease the quantity of those enzymes—and/or how active they are.

    Dr. Kata Wolff Pederson and her team of researchers at Aarhus University in Denmark examined the livers of recently deceased donors in ways that can’t (ethically) be done with live patients, and were able to find the associations between various lifestyle factors and different levels of enzymes responsible for drug metabolism.

    And it’s not always how you might think!

    Some key things they found:

    • Smokers have twice as high levels of enzyme CYP1A2 than non-smokers, which results in the faster metabolism of a lot of drugs.
    • Drinkers have 30% higher levels of enzyme CYP2E1, which also results in a faster metabolism of a lot of drugs.
    • Patients with obesity have 50% lower levels of enzyme CYP3A4, resulting in slower metabolism of many drugs

    This gets particularly relevant when we take into account the next fact:

    • Of the individuals in the study, 40% died from poisoning from a mixture of drugs (usually: prescription and otherwise)

    Read in full: Sex- and Lifestyle-Related Factors are Associated with Altered Hepatic CYP Protein Levels

    Read a pop-sci article about it: Your lifestyle can determine how well your medicine will work

    How much does the metabolism speed matter?

    It can matter a lot! If you’re taking drugs and carefully abiding by the dosage instructions, those instructions were assuming they know your speed of metabolism, and this is based on an average.

    • If your metabolism is faster, you can get too much of a drug too quickly, and it can harm you
    • If your metabolism is faster, it also means that while yes it’ll start working sooner, it’ll also stop working sooner
      • If it’s a painkiller, that’s inconvenient. If it’s a drug that keeps you alive, then well, that’s especially unfortunate.
    • If your metabolism is slower, it can mean your body is still processing the previous dose(s) when you take the next one, and you can overdose (and potentially die)

    We touched on this previously when we talked about obesity in health care settings, and how people can end up getting worse care:

    Let’s Shed Some Obesity Myths

    As for alcohol and drugs? Obviously we do not recommend, but here’s some of the science of it with many examples:
