Detox: What’s Real, What’s Not, What’s Useful, What’s Dangerous?

Out of the subscribers who engaged in the poll, it looks like we have a lot of confidence in at least some detox approaches being useful!

Celery juice is most people’s go-to, and indeed it was the only one to get mentioned in the comments added. So let’s take a look at that first…

Celery juice

Celery juice is enjoyed by many people, with many health benefits in mind, including to:

  • reduce inflammation
  • lower blood pressure
  • heal the liver
  • fight cancer
  • reduce bloating
  • support the digestive system
  • increase energy
  • support weight loss
  • promote good mental health

An impressive list! With such an impressive list, we would hope for an impressive weight of evidence, so regular readers might be wondering why those bullet-pointed items aren’t all shiny hyperlinks to studies backing those claims. The reason is…

There aren’t any high-quality studies that back any of those claims.

We found one case study (so, a study with a sample size of one; not amazing) that observed a blood pressure change in an elderly man after drinking celery juice.

Rather than trawl up half of PubMed to show the lacklustre results in a way more befitting of Research Review Monday, though, here’s a nice compact article detailing the litany of disappointment that is science’s observations regards celery juice:

Why Are People Juicing Their Celery? – by Allison Webster, PhD, RD

A key take-away is: juicing destroys the fiber that is celery’s biggest benefit, and its phytochemicals are largely unproven to be of use.

If you enjoy celery, great! It (when not juiced) is a great source of fiber and water. If you juice it, it’s a great source of water.

Activated Charcoal

Unlike a lot of greenery—whose “cleansing” benefits mostly come from fiber and disappear when juiced—activated charcoal has a very different way of operating.

Activated charcoal is negatively charged on a molecular level*, and that—along with its porous nature—traps toxins. It really is a superpowered detox that actually works very well indeed.

But…

It works very well indeed. It will draw out toxins so well, that it’s commonly used to treat poisonings. “Wait”, we hear you say, “why was that a but”?

It doesn’t know what a toxin is. It just draws out all of the things. You took medicine recently? Not any more you didn’t. You didn’t even take that medication orally, you took it some other way? Activated charcoal does not care:

Does this mean that activated charcoal can be used to “undo” a night of heavy drinking?

Sadly not. That’s one of the few things it just doesn’t work for. It won’t work for alcohol, salts, or metals:

The Use of Activated Charcoal to Treat Intoxications

*Fun chemistry mnemonic about ions:

Cations are pussitive

Anions (by process of elimination) are negative

Onions taste good in salad (remember also: Cole’s Law)

Bottom line on detox foods/drinks:

  • Fiber is great; juicing removes fiber. Eat your greens (don’t drink them)!
  • Activated charcoal is the heavy artillery of detoxing
  • Sometimes it will remove things you didn’t want removed, though
  • It also won’t help against alcohol, sadly

    Research Review: Collagen

    For something that’s a very popular supplement, not many people understand what collagen is, where it comes from, or what it does.

    In a nutshell:

    Collagen is a kind of protein. Our bodies make it naturally, and we can also get more in our diet and/or take extra as a supplement.

    Our bodies use collagen in connective tissue, skin, tendon, bone, and cartilage. It has many functions, but a broad description would be “holding things together”.

    As we get older, our bodies produce less collagen. Signs of this include wrinkles, loss of skin hydration, and joint pain.

    Quick test: pinch the skin on the middle of the back of one of your hands, and then watch what happens when you get low. How quickly and easily did your skin returns to its original shape?

    If it was pretty much instantanous and flawless, congratulations, you have plenty of collagen (and also elastin). If you didn’t, you are probably low on both!

    (they are quite similar proteins and are made from the same base “stuff”, so if you’re low on one, you’ll usually be low on both)

    Quick note: A lot of research out there has been funded by beauty companies, so we had our work cut out for us today, and have highlighted where any research may be biased.

    More than skin deep

    While marketing for collagen is almost exclusively aimed at “reduce wrinkles and other signs of aging”, it does a lot more than that.

    You remember we mentioned that many things from the bones outward are held together by collagen? We weren’t kidding…

    Read: Osteoporosis, like skin ageing, is caused by collagen loss which is reversible

    Taking extra collagen isn’t the only way

    We can’t (yet!) completely halt the age-related loss of collagen, but we can slow it, with our lifestyle choices:

    Can I get collagen from food?

    Yep! Just as collagen holds our bodies together, it holds the bodies of other animals together. And, just like collagen is found in most parts of our body but most plentifully in our skin and bones, that’s what to eat to get collagen from other animals, e.g:

    • Chicken skin
    • Fish skin
    • Bone broth ← health benefits and recipes at this link!

    What about vegans?

    Yes, vegans are also held together by collagen! We do not, however, recommend eating their skin or boiling their bones into broth. Ethical considerations aside, cannibalism can give you CJD!

    More seriously, if you’re vegan, you can’t get collagen from a plant-based diet, but you can get the stuff your body uses to make collagen. Basically, you want to make sure you get plenty of:

    Read: Diet and Dermatology: The Role of a Whole-food, Plant-based Diet in Preventing and Reversing Skin Aging

    Just be sure to continue to remember to avoid highly-processed foods. So:

    • Soy mince/chunks whose ingredients list reads: “soya”? Yes!
    • The Incredible Burger or Linda McCartney’s Sausages? Sadly less healthy

    Read: Advanced Glycation End Products in Foods and a Practical Guide to Their Reduction in the Diet

    Meat-eaters might want to read that one too. By far the worst offenders for AGEs (Advanced Glycation End Products, which can not only cause collagen to stiffen, but also inactivate proteins responsible for collagen repair, along with doing much more serious damage to your body’s natural functions) include:

    • Hot dogs
    • Bacon
    • Fried/roasted/grilled meats

    Is it worth it as a supplement?

    That depends on you, your age, and your lifestyle, but it’s generally considered safe*

    *if you have a seafood allergy, be careful though, as many supplements are from fish or shellfish—you will need to find one that’s free from your allergen

    Also, all collagen is animal-derived. So if you’re a vegan, decide for yourself whether this constitutes medicine and if so, whether that makes it ethically permissible to you.

    With that out of the way:

    What the science says on collagen supplementation

    Collagen for skin

    Read: Effects of collagen supplementation on skin aging (systematic review and meta-analysis)

    The short version is that they selected 19 studies with over a thousand participants in total, and they found:

    In the meta-analysis, a grouped analysis of studies showed favorable results of hydrolyzed collagen supplementation compared with placebo in terms of skin hydration, elasticity, and wrinkles.

    The findings of improved hydration and elasticity were also confirmed in the subgroup meta-analysis.

    Based on results, ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration.

    Caveat: while that systematic review had no conflicts of interests, at least some of the 19 studies will have been funded by beauty companies. Here are two, so that you know what that looks like:

    Funded by Quiris to investigate their own supplement, Elasten®:

    A Collagen Supplement Improves Skin Hydration, Elasticity, Roughness, and Density

    Funded by BioCell to investigate their own supplement, BioCell Collagen:

    The Effects of Skin Aging Associated with the Use of BioCell Collagen

    A note on funding bias: to be clear, the issue is not that the researchers might be corrupt (though that could happen).

    The issue is more that sometimes companies will hire ten labs to do ten research studies… and then pull funding from ones whose results aren’t going the way they’d like.

    So the “best” (for them) study is the one that gets published.

    Here’s another systematic review—like the one at the top of this section—that found the same, with doses ranging from 2.5g–15g per day for 8 weeks or longer:

    Read: Oral Collagen Supplementation: A Systematic Review of Dermatological Applications

    Again, some of those studies will have been funded by beauty companies. The general weight of evidence does seem clear and favorable, though.

    Collagen for bones

    Here, we encountered a lot less in the way of potential bias, because this is simply marketed a lot less. Despite being arguably far more important!

    We found a high quality multi-vector randomized controlled study with a sample size of 131 postmenopausal women. They had these women take 5g collagen supplement (or placebo), and studied the results over the course of a year.

    They found:

    • The intake of the supplement increased bone mineral density (BMD)
    • Supplementation was also associated with a favorable shift in bone markers, indicating:
      • increased bone formation
      • reduced bone degradation

    Read: Specific Collagen Peptides Improve Bone Mineral Density and Bone Markers in Postmenopausal Wome

    A follow-up study with 31 of these women found that taking 5 grams of collagen daily for a total of 4 years was associated with a progressive increase in BMD.

    You might be wondering if collagen also helps against osteoarthritis.

    The answer is: yes, it does (at least, it significantly reduces the symptoms)

    Read: Effect of collagen supplementation on osteoarthritis symptoms

    In summary:

    • You need collagen for health skin, bones, joints, and more
    • Your body makes collagen from your food
    • You can help it by getting plenty of protein, vitamins, and minerals
    • You can also help it by not doing the usual Bad Things™ (smoking, drinking, eating processed foods, especially processed meats)
    • You can also eat collagen directly in the form of other animals’ skin and bones
    • You can also buy collagen supplements (but watch out for allergens)

    Want to try collagen supplementation?

    We don’t sell it (or anything else), but for your convenience…

    Check it out: Hydrolyzed Collagen Peptides (the same as in most of the above studies), 90 days supply at 5g/day

    We selected this one because it’s the same kind used in many of the studies, and it doesn’t contain any known allergens.

    It’s bovine collagen, meaning it’s from cows, so it’s not vegan, and also some subscribers may want to abstain for religious reasons. We respect that, and/but make our recommendations based solely on the science of health and productivity.

    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

    ❝I like the recipes. Most don’t seem to include nutritional profile. would lilke to see that. Macro/micro world…. Thank you❞

    We’re glad you’re enjoying them! There are a couple of reasons why we don’t, but the reasons can be aggregated into one (admittedly rare) concept: honesty

    To even try to give you these figures, we’d first need to use the metric system (or at least, a strictly mass-based system) which would likely not go well with our largely American readership, because “half a bulb of garlic, or more if you like”, and “1 cucumber” or “1 cup chopped carrot” could easily way half or twice as much, depending on the sizes of the vegetables or the chopping involved, and in the case of chopped vegetables measured by the cup, even the shape of the cup (because of geometry and the spaces left; it’s like Tetris in there). We can say “4 cups low-sodium broth” but we can’t say how much sodium is in your broth. And so on.

    And that’s without getting into the flexibility we offer with substitutions, often at a rate of several per recipe.

    We’d also need to strictly regulate your portion sizes for you, because we (with few exceptions, such as when they are a given number of burger patties, or a dessert-in-a-glass, etc) give you a recipe for a meal and leave it to you how you divide it and whether there’s leftovers.

    Same goes for things like “Extra virgin olive oil for frying”; a recipe could say to use “2 tbsp” but let’s face it, you’re going to use what you need to use, and that’s going to change based on the size of your pan, how quickly it’s absorbed into the specific ingredients that you got, which will change depending on how fresh they are, and things like that.

    By the time we’ve factored in your different kitchen equipment, how big your vegetables are, the many factors effecting how much oil you need, substitutions per recipe per making something dairy-free, or gluten-free, or nut-free, etc, how big your portion size is (we all know that “serves 4” is meaningless in reality)… Even an estimated average would be wildly misleading.

    So, in a sea of recipes saying “500 kcal per serving” from the same authors who say you can caramelize onions in 4–5 minutes “or until caramelized” and then use the 4–5 minutes figure for calculating the overall recipe time… We prefer to stay honest.

    PS: for any wondering, caramelizing onions takes closer to 45 minutes than 4–5 minutes, and again will depend on many factors, including the onions, how finely you chopped them, the size and surface of your pan, the fat you’re using, whether you add sugar, what kind, how much you stir them, the mood of your hob, and the phase of the moon. Under very favorable circumstances, it could conceivably be rushed in 20 minutes or so, but it could also take 60. Slow-cooking them (i.e. in a crock pot) over 3–4 hours is a surprisingly viable “cheat” option, by the way. It’ll take longer, obviously, but provided you plan in advance, they’ll be ready when you need them, and perfectly done (the same claim cannot be made if you budgeted 4–5 minutes because you trusted a wicked and deceitful author who wants to poop your party).

    Take care!

    So, no question/request too big or small

    ❝I take CBD gummies. I don’t know if they are worth buying. Can you find a study on the effectiveness of gummies❞

    If you take them, and you’re not sure whether they’re worth it, then it sounds like you’re not getting any observable benefit from them?

    If so, that would seem to answer your question, since presumably the reason that you are taking them is for relaxation and/or pain relief, so if you’re not getting the results you want, then no, they are not worth it.

    However! CBD gummies are an incredibly diverse and not-well-studied product, so far, given the relative novelty of their legality. By diverse we mean, they’re not well-standardized.

    In other words: the CBD gummies you get could be completely unlike CBD gummies from a different source.

    CBD itself (i.e. in forms other than just gummies, and mostly as oil) has been studied somewhat better, and we did a main feature on it here:

    One thing that we would add is that even though CBD is generally recognized as safe, it is possible to overdose on CBD gummies, so do watch your limits:

  • Turmeric (Curcumin) Dos and Don’ts With Dr. Kim

    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.

    Turmeric is a fabulous spice, most well-known for its anti-inflammatory powers; its antioxidant effects benefit all of the body, including the brain. While it fights seemingly everything from arthritis to atherosclerosis to Alzheimer’s and more, it also boosts brain-derived neurotrophic factor, looks after your cardiovascular health, holds back diabetes, reduces the risk of cancer, fights depression, slows aging, and basically does everything short of making you sing well too.

    Dr. Leonid Kim goes over the scientific evidence for these, and also talks about some of the practicalities of taking turmeric, and safety considerations.

    For the most part, turmeric is very safe even at high doses (up to 8g at least); indeed, at smaller doses (e.g. 500mg) it largely does the same job as non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, with fewer problems.

    It also does the job of several antidiabetic medications, by increasing uptake of glucose (thus reducing blood sugar levels) while simultaneously decreasing the glucose secretion from the liver. It does this by regulating the AMPK signalling pathway, just like metformin—while again, being safer.

    Dr. Kim also looks at the (good!) evidence for turmeric in managing PCOS and undoing NAFLD; so far, so good.

    Dosage: he bids us pay attention whether we’re taking it as turmeric itself or as curcumin standardized extract. The latter is the active compound, and in principle more powerful, but in practice it can get metabolized too quickly and easily—before it can have its desired effect. So, turmeric itself is a very good choice.

    Absorption: since we do want it to be absorbed well, though, he does recommend taking it with piperine (as in black pepper).

    You may be thinking: isn’t this going to cause the same problem you were just talking about, and cause it to be metabolized too quickly? And the answer is: no! How piperine works is almost the opposite; it protects the curcumin in the turmeric from our digestive enzymes, and thus allows them to get absorbed without being broken down too quickly—thus increasing the bioavailability by slowing the process down.

    Lipophilia: no, that’s not a disease (or a fetish), rather it means that curcumin is soluble in fats, so we should take it near in time to a meal that contains at least a tablespoon of oil in total (so if you’re cooking a curry with your turmeric, this need is covered already, for example).

    Supplement provenance: he recommends picking a supplement that’s been tested by a reputable 3rd party, as otherwise turmeric can be quite prone to impurities (which can include lead and arsenic, so, not great).

    Contraindications: for some people, curcumin can cause gastrointestinal issues (less likely if taking with meals), and also, it can interact with blood-thinners. While taking aspirin or curcumin alone might help avoid circulatory problems, taking both could increase the bleeding risk for some people, for example. Similarly, if taking curcumin and metformin while diabetic, one must watch out for the combination being too effective at lowering blood sugar levels, and thus causing hypoglycemia instead. Similar deal with blood pressure medications.

  • Do You Know Which Supplements You Shouldn’t Take Together? (10 Pairs!)

    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.

    Dr. LeGrand Peterson wants us to get the most out of our supplements, so watch out for these…

    Time to split up some pairs…

    In most cases these are a matter of competing for absorption; sometimes to the detriment of both, sometimes to the detriment of one or the other, and sometimes, the problem is entirely different and they just interact in a way that could potentially cause other problems. Dr. Peterson advises as follows:

    1. Vitamin C and vitamin B12: taking these together can reduce the absorption of Vitamin B12, as vitamin C can overpower it.
    2. Vitamin C and copper: high amounts of vitamin C can decrease copper absorption, especially in those who are severely copper deficient.
    3. Magnesium and calcium: these two minerals compete for absorption in the intestines, potentially reducing the effectiveness of both.
    4. Calcium and iron: calcium can decrease iron absorption, so they should not be taken together, especially if you are iron deficient.
    5. Calcium and zinc: calcium also competes with zinc, reducing zinc absorption; they should be taken at different times.
    6. Zinc and copper: zinc and copper compete for absorption, so they should be taken at separate times.
    7. Iron and zinc: iron can decrease zinc absorption, and thus, they should not be taken together.
    8. Iron and green tea: perhaps a surprising one, but green tea can reduce iron absorption, so they should not be taken simultaneously.
    9. Vitamin E and vitamin K: vitamin E increases bleeding risk, while vitamin K promotes clotting, making them opposites and risky to take together.
    10. Fish oil and ginkgo biloba: both are anticoagulants and can increase the risk of bleeding, especially if taken with blood thinners like warfarin.

    If you need to take supplements that compete (or conflict or otherwise potentially adversely interact) with each other, it’s recommended to separate them by at least 4 hours, or better yet, take one in the morning and the other at night. If in doubt, do speak with your pharmacist or doctor for personalized advice

    You may be thinking: half my foods contain half of these nutrients! And yes, assuming you have a nutritionally dense diet, this is probably the case. Foods typically release nutrients more slowly than supplements, and unlike supplements, do not usually contain megadoses (although they can, such as the selenium content of Brazil nuts, or vitamin A in carrots). Basically, food is in most cases safer and gentler than supplements. If concerned, do speak with your nutritionist or doctor for personalized advice.

  • The New Menopause – by Dr. Mary Claire Haver

    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 is most famous for “The Galveston Diet”, which book is astonishingly similar in its content, chapters, format, etc to Nikki Williams’ “It’s Not You, It’s Your Hormones” which came out a few years previously but didn’t get the same marketing.

    Nonetheless, this time Dr. Haver has something new to add, and we think it’s worth a read.

    The general theme of this book is a comprehensive overview of the menopause, experientially (subjective to the person going through it) and empirically (by science), from start to finish and beyond. This book’s more about human physiology, and less about diet than the previous.

    Dr. Haver also discusses in-depth how estrogen is thought of as a sex hormone (and it is), to the point that people consider it perhaps expendable, and forget (or are simply unaware) that we have estrogen receptors throughout our bodies and estrogen is vital for maintaining many other bodily functions, including your heart, cognitive function, bone integrity, blood sugar balance, and more.

    (in case you’re wondering “why don’t men fall to bits, then?”, don’t worry, their testosterone does these things for them. Testosterone is orders of magnitude less potent than estrogen, mg for mg, so they need a lot more of it, but under good conditions they produce plenty so it’s fine)

    But, the amount of testosterone available to peri/postmenopausal women is simply not enough to do that job (and it’d also result in a transition of secondary sex characteristics, which for most people would be very unwanted), so, something else needs to be done.

    Dr. Haver also discusses in detail the benefits and risks of HRT and how to get/manage them, respectively, with the latest up-to-date research (at time of going to print; the book was published in April 2024).

    Bottom line: if you want to know what’s going on with your peri- or post-menopausal body and how it could be better (or if you want to know what’s going on with someone else approaching/experiencing menopause), then this is a top-tier book.
