Our Verdict

When comparing grapefruit to orange, we picked the orange.

Why?

It’s easy, when guessing which is the healthier out of two things, to guess that the more expensive or perhaps less universally available one is the healthier. But it’s not always so, and today is one of those cases!

In terms of macros, they are very similar fruits, with almost identical levels of carbohydrates, proteins, and fats, as well as water. Looking more carefully, we find that grapefruit’s sugars contain a slightly high proportion of fructose; not enough to make it unhealthy by any means (indeed, no whole unprocessed fruit is unhealthy unless it’s literally poisonous), but it is a thing to note if we’re micro-analysing the macronutrients. Also, oranges have slightly more fiber, which is always a plus.

When it comes to vitamins, oranges stand out with more of vitamins B1, B2, B3, B6, B9, C, and E, while grapefruit boasts more vitamin A (hence its color). Still, we’re calling this category another win for oranges.

In the category of minerals, oranges again sweep with more calcium, copper, iron, magnesium, manganese, potassium, and selenium, while grapefruit has just a little more phosphorus. So, another easy win for oranges.

One final consideration that’s not shown in the nutritional values, is that grapefruit contains 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. It can also be found in lower quantities in Seville (sour) oranges, and it’s not present (or at least, if it is, it’s in truly tiny quantities) in most oranges.

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, today’s sections add up to an overwhelming win for oranges!

  • How I Cured My Silent Reflux – by Don Daniels

    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.

    Acid reflux, in its various forms (not all of which include heartburn as a symptom!), affects around 1 in 8 people. Often it takes the form of coughing or excess mucus after eating, and it can trigger ostensibly random sweats, for example.

    Don Daniels does an excellent job of demystifying the various kinds of acid reflux, explaining clearly and simply the mechanics of what is going on for each of them and why.

    Further, he talks about the medications that can make things worse (and how and why), and supplements that can make it better (and supplements that can make it worse, too!), and a multiphase plan (diet on, meds weaned off, supplements on, supplements weaned off when asymptomatic, diet adjust to a new normal) to get free from acid reflux.

    The writing style is simple, clear, and jargon-free, while referencing plenty of scientific literature, often quoting from it and providing sources, much like we often do at 10almonds. There are 50+ such references in all, for a 105-page book.

    So, do also note that yes, it’s quite a short book for the price, but the content is of value and wouldn’t have benefitted from padding of the kind that many authors do just to make the book longer.

    Bottom line: if you have, or suspect you may have, an acid reflux condition of any kind, then this book can guide you through fixing that.

  • Who Screens The Sunscreens?

    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 Screen The Sunscreens!

    Yesterday, we asked you what your sunscreen policy was, and got a spread of answers. Apparently this one was quite polarizing!

    One subscriber who voted for “Sunscreen is essential to protect us against skin aging and cancer” wrote:

    ❝My mom died of complications from melanoma, so we are vigilant about sun and sunscreen. We are a family of campers and hikers and gardeners—outdoors in all seasons—and we never burn❞

    Our condolences with regard to your mom! Life is so precious, and when something like that happens, it tends to stick with us. We’re glad you and your family are taking care of yourselves.

    Of the subscribers who voted for “I put some on if I think I might otherwise get sunburned”, about half wrote to express uncertainties:

    • uncertainty about how safe it is, and
    • uncertainty about how helpful it is

    …so we’re going to tackle those questions in a moment. But what of those who voted for “Sunscreen is full of harmful chemicals that can cause cancer”?

    Of those, only one wrote a message, which was to say one has to be very careful of what is in the formula.

    Let’s take a look, then…

    Sunscreen is full of harmful chemicals that can cause cancer: True or False?

    False—according to current best science. Research is ongoing!

    There are four main chemicals (found in most sunscreens) that people tend to worry about:

    • Abobenzone
    • Oxybenzone
    • Octocrylene
    • Ecamsule

    Now, these two sound like four brands of rocket fuel, but then, dihydrogen monoxide (DHMO), which is also found in most sunscreens, sounds like a deadly toxin too. That’s water, by the way.

    But what of these four chemicals? Well, as we say, research is ongoing, but we found a study that measured all four, to see how much got into the blood, and what adverse effects, if any, this caused.

    We’ll skip to their conclusion:

    ❝In this preliminary study involving healthy volunteers, application of 4 commercially available sunscreens under maximal use conditions resulted in plasma concentrations that exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens. The systemic absorption of sunscreen ingredients supports the need for further studies to determine the clinical significance of these findings. These results do not indicate that individuals should refrain from the use of sunscreen.❞

    Now, “exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens” sounds alarming, so why did they close with the words “These results do not indicate that individuals should refrain from the use of sunscreen”?

    Let’s skip back up to a line from the results:

    ❝The most common adverse event was rash, which developed in 1 participant with each sunscreen.❞

    This was most probably due to the oxybenzone, which can cause allergic skin reactions in some people.

    Let us take a moment to remember the most common adverse event that occurs from not wearing sunscreen: sunburn!

    You can read the full study here:

    Effect of Sunscreen Application Under Maximal Use Conditions on Plasma Concentration of Sunscreen Active Ingredients—A Randomized Clinical Trial

    None of those ingredients have been found to be carcinogenic, even at the maximal blood plasma concentrations studied, from applications 4x/day to 75% of the body.

    UVA rays, on the other hand, are absolutely very much known to cause cancer, and the effect is cumulative.

    Sunscreen is essential to protect us against skin aging and cancer: True or False?

    True, unequivocally, unless we live indoors and/or otherwise never go about under sunlight.

    “But our ancestors—” lived under the same sun we do, and either used sunscreen or got advanced skin aging and cancer.

    Sunscreen of times past ranged from mud to mineral lotions, but it’s pretty much always existed. Even non-human animals that have skin and don’t have fur or feathers, tend to take mud-baths in sunny parts of the world.

    If you’d like to avoid oxybenzone and other chemicals, though, you might have your reasons. Maybe you’re allergic, or maybe you read that it’s a potential endocrine disruptor with estrogen-like and anti-androgenic properties that you don’t want.

    There are other options, to include physical blockers containing zinc and titanium dioxide, which are generally recognized as safe and effective ingredients.

    If you’re interested, you can even make your own sunscreen that blocks both UVA and UVB rays (UVA is what causes skin cancer; UVB is “milder” and is what causes sunburn):

  • Lycopene’s Benefits For The Gut, Heart, Brain, & More

    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.

    What Doesn’t Lycopene Do?

    Lycopene is an antioxidant carotenoid famously found in tomatoes; it actually appears in even higher levels in watermelon, though. If you are going to get it from tomato, know that cooking improves the lycopene content rather than removing it (watermelon, on the other hand, can be enjoyed as-is and already has the higher lycopene content).

    Antioxidant properties

    Let’s reiterate the obvious first, for the sake of being methodical and adding a source. Lycopene is a potent antioxidant with multiple health benefits:

    Lycopene: A Potent Antioxidant with Multiple Health Benefits

    …and as such, it does all the things you might reasonably expect and antioxidant to do. For example…

    Anti-inflammatory properties

    In particular, it regulates macrophage activity, reducing inflammation while improving immune response:

    Lycopene Regulates Macrophage Immune Response through the Autophagy Pathway Mediated by RIPK1

    As can be expected of most antioxidants and anti-inflammatory agents, it also has…

    Anticancer properties

    Scientific papers tend to be “per cancer type”, so we’re just going to give one example, but there’s pretty much evidence for its utility against most if not all types of cancer. We’re picking prostate cancer though, as it’s one that’s been studied the most in the context of lycopene intake—in this study, for example, it was found that men who enjoyed at least two servings of lycopene-rich tomato sauce per week were 30% less likely to develop prostate cancer than those who didn’t:

    Dietary lycopene intake and risk of prostate cancer defined by ERG protein expression

    If you’d like to see something more general, however, then check out:

    Potential Use of Tomato Peel, a Rich Source of Lycopene, for Cancer Treatment

    It also fights Candida albicans

    Ok, this is not (usually) so life-and-death as cancer, but reducing our C. albicans content (specifically: in our gut) has a lot of knock-on effects for other aspects of our health, so this isn’t one to overlook:

    Lycopene induces apoptosis in Candida albicans through reactive oxygen species production and mitochondrial dysfunction

    The title does not make this clear, but yes: this does mean it has an antifungal effect. We mention this because often cellular apoptosis is good for an overall organism, but in this case, it simply kills the Candida.

    It’s good for the heart

    A lot of studies focus just on triglyceride markers (which lycopene improves), but more tellingly, here’s a 10-year observational study in which diets rich in lycopene were associated to a 17–26% lower risk of heart disease:

    Relationship of lycopene intake and consumption of tomato products to incident CVD

    …and a 39% overall reduced mortality in, well, we’ll let the study title tell it:

    Higher levels of serum lycopene are associated with reduced mortality in individuals with metabolic syndrome

    …which means also:

    It’s good for the brain

    As a general rule of thumb, what’s good for the heart is good for the brain (because the brain needs healthy blood flow to stay healthy, and is especially vulnerable when it doesn’t get that), and in this case that rule of thumb is also borne out by the post hoc evidence, specifically yielding a 31% decreased incidence of stroke:

    Dietary and circulating lycopene and stroke risk: a meta-analysis of prospective studies

    Is it safe?

    As a common food product, it is considered very safe.

    If you drink nothing but tomato juice all day for a long time, your skin will take on a reddish hue, which will go away if you stop getting all your daily water intake in tomato juice.

    In all likelihood, even if you went to extremes, you would get sick from the excess of vitamin A (generally present in the same foods) sooner than you’d get sick from the excess of lycopene.

    Want to try some?

    We don’t sell it, and also we recommend simply enjoying tomatoes, watermelons, etc, but if you do want a supplement, here’s an example product on Amazon

    Enjoy!

    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:

    Walking, Better

    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:

    Wendy Suzuki | IntenSati

    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❞

    ~ Dr. Wendy Suzuki

    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. ❞

    ~ Dr. Wendy Suzuki

    …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. ❞

    ~ Dr. Wendy Suzuki

    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.

    Dr. Devi’s Spectrum of Hope

    This is Dr. Gayatri Devi. She’s a neurologist, board-certified in neurology, pain medicine, psychiatry, brain injury medicine, and behavioral neurology.

    She’s also a Clinical Professor of Neurology, and Director of Long Island Alzheimer’s Disease Center, Fellow of the American Academy of Neurology, and we could continue all day with her qualifications, awards and achievements but then we’d run out of space. Suffice it to say, she knows her stuff.

    Especially when it comes to the optimal treatment of stroke, cognitive loss, and pain.

    In her own words:

    ❝Helping folks live their best lives—by diagnosing and managing complex neurologic disorders—that’s my job. Few things are more fulfilling! For nearly thirty years, my focus has been on brain health, concussions, Alzheimer’s and other dementias, menopause related memory loss, and pain.❞

    ~ Dr. Gayatri Devi

    Alzheimer’s is more common than you might think

    According to Dr. Devi,

    ❝97% of patients with mild Alzheimer’s disease don’t even get diagnosed in their internist offices, and half of patients with moderate Alzheimer’s don’t get diagnosed.

    What that means is that the percentage of people that we think about when we think about Alzheimer’s—the people in the nursing home—that’s a very, very small fraction of the entirety of the people who have the condition❞

    Her most critical advice? Reallocate your worry.

    A lot of people understandably worry about a genetic predisposition to Alzheimer’s, especially if an older relative died that way.

    However, Dr. Devi points out that under 5% of Alzheimer’s cases are from genetics, and the majority of Alzheimer’s cases can be prevented be lifestyle interventions.
