The Bitter Truth About Coffee (or is it?)

Yesterday, we asked you for your (health-related) views on coffee. The results were clear: if we assume the responses to be representative, we’re a large group of coffee-enthusiasts!

One subscriber who voted for “Coffee is a healthy stimulant, hydrating, and full of antioxidants” wrote:

❝Not so sure about how hydrating it is! Like most food and drink, moderation is key. More than 2 or 3 cups make me buzz! Just too much.❞

And that fine point brings us to our first potential myth:

Coffee is dehydrating: True or False?

False. With caveats…

Coffee, in whatever form we drink it, is wet. This may not come as a startling revelation, but it’s an important starting point. It’s mostly water. Water itself is not dehydrating.

Caffeine, however, is a diuretic—meaning you will tend to pee more. It achieves its diuretic effect by increasing blood flow to your kidneys, which prompts them to release more water through urination.

See: Effect of caffeine on bladder function in patients with overactive bladder symptoms

How much caffeine is required to have a diuretic effect? About 4.5 mg/kg.

What this means in practical terms: if you weigh 70kg (a little over 150lbs), 4.5×70 gives us 315.

315mg is about how much caffeine might be in six shots of espresso. We say “might” because while dosage calculations are an exact science, the actual amount in your shot of espresso can vary depending on many factors, including:

  • The kind of coffee bean
  • How and when it was roasted
  • How and when it was ground
  • The water used to make the espresso
  • The pressure and temperature of the water

…and that’s all without looking at the most obvious factor: “is the coffee decaffeinated?”

If it doesn’t contain caffeine, it’s not diuretic. Decaffeinated coffee does usually contain tiny amounts of caffeine still, but with nearer 3mg than 300mg, it’s orders of magnitude away from having a diuretic effect.

If it does contain caffeine, then the next question becomes: “and how much water?”

For example, an Americano (espresso, with hot water added to make it a long drink) will be more hydrating than a ristretto (espresso, stopped halfway through pushing, meaning it is shorter and stronger than a normal espresso).

A subscriber who voted for “Coffee messes with sleep, creates dependency, is bad for the heart and gut, and is dehydrating too” wrote:

❝Coffee causes tachycardia for me so staying away is best. People with colon cancer are urged to stay away from coffee completely.❞

These are great points! It brings us to our next potential myth:

Coffee is bad for the heart: True or False?

False… For most people.

Some people, like our subscriber above, have an adverse reaction to caffeine, such as tachycardia. An important reason (beyond basic decency) for anyone providing coffee to honor requests for decaff.

For most people, caffeine is “heart neutral”. It doesn’t provide direct benefits or cause direct harm, provided it is enjoyed in moderation.

Some quick extra notes…

That’s all we have time for in myth-busting, but it’s worth noting before we close that coffee has a lot of health benefits; we didn’t cover them today because they’re not contentious, but they are interesting nevertheless:

Enjoy!

  • Zuranolone: What to know about the pill for postpartum depression

    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.

    In the year after giving birth, about one in eight people who give birth in the U.S. experience the debilitating symptoms of postpartum depression (PPD), including lack of energy and feeling sad, anxious, hopeless, and overwhelmed. 

    Postpartum depression is a serious, potentially life-threatening condition that can affect a person’s bond with their baby. Although it’s frequently confused with the so-called “baby blues,” it’s not the same. 

    The baby blues include similar, temporary symptoms that affect up to 80 percent of people who have recently given birth and usually go away within the first few weeks. PPD usually begins within the first month after giving birth and can last for months and interfere with a person’s daily life if left untreated. Thankfully, PPD is treatable and there is help available

    On August 4, the FDA approved zuranolone, branded as Zurzuvae, the first-ever oral medication to treat PPD. Until now, besides other common antidepressants, the only medication available to treat PPD specifically was the IV injection brexanolone, which is difficult to access and expensive and can only be administered in a hospital or health care setting. 

    Read on to find out more about zuranolone: what it is, how it works, how much it costs, and more. 

    What is zuranolone?

    Zurzuvae is the brand name for zuranolone, an oral medication to treat postpartum depression. Developed by Sage Therapeutics in partnership with Biogen, it’s now available in the U.S. Zurzuvae is typically prescribed as two 25 mg capsules a day for 14 days. In clinical trials, the medication showed to be fast-acting, improving PPD symptoms in just three days

    How does zuranolone work? 

    Zuranolone is a neuroactive steroid, a type of medication that helps the neurotransmitter GABA’s receptors, which affect how the body reacts to anxiety, stress, and fear, function better.

    “Zuranolone can be thought of as a synthetic version of [the neuroactive steroid] allopregnanolone,” says Dr. Katrina Furey, a reproductive psychiatrist, clinical instructor at Yale University, and co-host of the Analyze Scripts podcast. “Women with PPD have lower levels of allopregnenolone compared to women without PPD.”

    How is it different from other antidepressants?

    “What differentiates zuranolone from other previously available oral antidepressants is that it has a much more rapid response and a shorter course of treatment,” says Dr. Asima Ahmad, an OB-GYN, reproductive endocrinologist, and founder of Carrot Fertility

    “It can take effect as early as on day three of treatment, versus other oral antidepressants that can take up to six to 12 weeks to take full effect.” 

    What are Zurzuvae’s side effects? 

    According to the FDA, the most common side effects of Zurzuvae include dizziness, drowsiness, diarrhea, fatigue, the common cold, and urinary tract infection. Similar to other antidepressants, the medication may increase the risk of suicidal thoughts and actions in people 24 and younger. However, NPR noted that this type of labeling is required for all antidepressants, and researchers didn’t see any reports of suicidal thoughts in their trials.

    “Drug trials also noted that the side effects for zuranolone were not as severe,” says Ahmad. “[There was] no sudden loss of consciousness as seen with brexanolone or weight gain and sexual dysfunction, which can be seen with other oral antidepressants.”

    She adds: “Given the lower incidence of side effects and more rapid-acting onset, zuranolone could be a viable option for many,” including those looking for a treatment that offers faster symptom relief. 

    Can someone breastfeed while taking zuranolone?

    It’s complicated. In clinical trials, participants were asked to stop breastfeeding (which, according to Furey, is common in early clinical trials). 

    A small study of people who were nursing while taking zuranolone found that 0.3 percent of the medication dose was passed on to breast milk, which, Furey says, is a pretty low amount of exposure for the baby. Ahmad says that “though some data suggests that the risk of harm to the baby may be low, there is still overall limited data.”

    Overall, people should talk to their health care provider about the risks and benefits of breastfeeding while on the medication. 

    “A lot of factors will need to be weighed, such as overall health of the infant, age of the infant, etc., when making this decision,” Furey says. 

    How much does Zurzuvae cost? 

    Zurzuvae’s price before insurance coverage is $15,900 for the 14-day treatment. However, the Policy Center for Maternal Mental Health says insurance companies and Medicaid are expected to cover it because it’s the only drug of its kind. 

    Less than 1 percent of U.S. insurers have issued coverage guidelines so far, so it’s still unknown how much it will cost patients after insurance. Some insurers require patients to try another antidepressant first (like the more common SSRIs) before covering Zurzuvae. For uninsured and underinsured people, Sage Therapeutics said it will offer copay assistance

    The hefty price tag and potential issues with coverage may widen existing health disparities, says Ahmad. “We need to ensure that we are seeking out solutions to enable wide-scale access to all PPD treatments so that people have access to whatever treatment may work best for them.”

  • Here’s how to help protect your family from norovirus

    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 you need to know

    • Norovirus is a very contagious infection that causes vomiting and diarrhea.
    • The best way to help protect against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus.
    • If someone in your household has symptoms of norovirus, isolate them away from others, watch for signs of dehydration, and take steps to help prevent it from spreading.

    If you feel like everyone is sick right now, you’re not alone. Levels of respiratory illnesses like COVID-19, flu, and RSV remain remain high in many states, and the U.S. is also battling a wave of norovirus, one of several viruses that cause a very contagious infection of the stomach and intestines. 

    Although norovirus infections are more common during the colder months—it’s also called the “winter vomiting disease”—the virus can spread at any time. Right now, however, cases have more than doubled since last year’s peak.

    Read on to learn about the symptoms of norovirus, how it spreads, and what to do if someone in your household gets sick.

    What are the symptoms of norovirus?

    Norovirus is a very contagious infection that causes vomiting and diarrhea, which typically begins 12 to 48 hours after exposure to the virus. Additional symptoms may include stomach pain, body aches, headaches, and a fever. Norovirus typically resolves within three days, but people who are infected may still be contagious for up to two days after symptoms resolve.

    Norovirus may cause dehydration, or a dangerous loss of fluids, especially in young children and older adults. See a health care provider if you or someone in your household shows signs of dehydration, which may include decreased urination, dizziness, a dry mouth and throat, sleepiness, and crying without tears.

    How can you help protect against norovirus?

    You can get norovirus if you have close contact with someone who is infected, touch a contaminated surface and then touch your mouth or nose, or consume contaminated food or beverages.

    The best way to help protect yourself and others against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus. Other ways to help protect yourself may include cooking food thoroughly and washing fruits and vegetables before eating them.

    You can get sick with norovirus even if you’ve had it before, since there are many different strains.

    How can families help protect against the spread of norovirus at home?

    If someone in your household has symptoms of norovirus, isolate them away from others and watch for signs of dehydration. If you are sick with norovirus, do not prepare food for others in your household and use a separate bathroom, if possible.

    When cleaning up after someone who has norovirus, wear rubber, latex, or nitrile gloves. Then wash your hands thoroughly.

    Clean surfaces using a solution containing five to 25 tablespoons of bleach (that’s 12.5 fluid ounces, or just  over ¾ cup), per gallon of water. Leave the bleach-water mix on surfaces for at least five minutes before wiping it off.

    For more information, talk to your health care provider.

  • The Wim Hof Method – by Wim Hof

    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.

    In Wednesday’s main feature, we wrote about the Wim Hof Method, and/but only scratched the surface. Such is the downside of being a super-condensed newsletter! However, it does give us the opportunity to feature the book:

    The Wim Hof Method is definitely loudly trumpeted as “up there” with Atomic Habits or How Not To Die in the category of “life-changing” books. Why?

    Firstly, it’s a very motivational book. Hof is a big proponent of the notion “if you think you can or you think you can’t, you’re right” idea, practises what he preaches, and makes clear he’s not special.

    Secondly, it’s backed up with science. While it’s not a science-heavy book and that’s not the main focus, there are references to studies. Where physiological explanations are given for how certain things work, those explanations are sound. There’s no pseudoscience here, which is especially important for a book of this genre!

    What does the book have that our article didn’t? A good few things:

    • More about Hof’s own background and where it’s taken him. This is generally not a reason people buy books (unless they are biographies), but it’s interesting nonetheless.
    • A lot more advice, data, and information about Cold Therapy and how it can (and, he argues convincingly, should) be built into your life.
    • A lot about breathing exercises that we just didn’t cover at all in our article, but is actually an important part of the Wim Hof Method.
    • More about stepping through the psychological barriers that can hold us back.

    Bottom line: this book offers benefits that stretch into many areas of life, from some simple habits that can be built.

  • 28-Day FAST Start Day-by-Day – by Gin Stephens

    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 have previously reviewed Gin Stephens’ other book, “Fast. Feast. Repeat.”, so what’s so special about this one that it deserves reviewing too?

    This one is all about troubleshooting the pitfalls that many people find when taking up intermittent fasting.

    To be clear: the goal here is not a “28 days and yay you did it, put that behind you now”, but rather “28 days and you are now intermittently fasting easily each day and can keep it up without difficulty”. As for the difficulties that may arise early in the 28 days…

    Not just issues of willpower, but also the accidental breaks. For example, some artificial sweeteners, while zero-calorie, trigger an insulin response, which breaks the fast on the metabolic level (avoiding that is the whole point of IF). Lots of little tips like that peppered through the book help the reader to stop accidentally self-sabotaging their progress.

    The author does talk about psychological issues too, and also how it will feel different at first while the liver is adapting, than later when it has already depleted its glycogen reserves and the body must burn body fat instead. Information like that makes it easier to understand that some initial problems (hunger, getting “hangry”, feeling twitchy, or feeling light-headed) will last only a few weeks and then disappear.

    So, understanding things like that makes a big difference too.

    The style of the book is simple and clear pop-science, with lots of charts and bullet points and callout-boxes and the like; it makes for very easy reading, and very quick learning of all the salient points, of which there are many.

    Bottom line: if you’ve tried intermittent fasting but struggled to make it stick, this book can help you get to where you want to be.

  • Strong Curves – by Bret Contreras & Kellie Davis

    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 title (and subtitle) is, of course, an appeal to vanity. However, the first-listed author is well-known as “The Glute Guy”, and he takes this very seriously, not just for aesthetic reasons but also for practical reasons.

    After all, when it comes to posture and stability, a lot rests on our hips, and hips, well, they rest on our butt and thighs. What’s more, the gluteus maximus is the largest muscle in the human body, so really, is it a good one to neglect? Probably not, and your lower back will definitely thank you for keeping your glutes in good order, too.

    That said, while it’s a focal point, it’s not the be-all-and-end-all, and this book does cover the whole body.

    The book takes the reader from “absolute beginner” to “could compete professionally”, with clearly-illustrated and well-described exercises. We also get a strong “crash course” in the relevant anatomy and physiology, and even a chapter on nutrition, which is a lot better than a lot of exercise books’ efforts in that regard.

    For those who like short courses, this book has several progressive 12-week workout plans that take the reader from a very clear starting point to a very clear goal point.

    Another strength of the book is that while a lot of exercises expect (and require) access to a gym, there are also whole sections of “at home / bodyweight” exercises, including 12-week workout plans for such, as described above.

    Bottom line: there’s really nothing bad that this reviewer can find to say about this one—highly recommendable to any woman who wants to get strong while keeping a feminine look.

    Click here to check out Strong Curves, and rebuild your body, your way!

    PS: at first glance, the cover art looks like an AI model; it’s not; that’s the co-author Kellie Davis, who also serves as the model through the book’s many photographic illustrations.

  • The Other Alzheimer’s Risk Factor

    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 usually-listed 7 known risk factors of dementia (in general, not just Alzheimer’s) do not include today’s item. For a recap, those were:

    The 7 Known Risk Factors For Dementia

    The bonus risk factor

    This idea is not completely novel; it’s been known for a while that traumatic brain injury (TBI) can increase the risk of dementia, but it has generally been chalked up to “if you damage an organ, then that organ does not function so well afterwards”.

    However, in the case of Alzheimer’s, it seems there’s something deeper at play. Specifically, a study that found…

    ❝…traumatic brain injury alters the small vessels in the brain, resulting in an accumulation of amyloid beta—a hallmark of Alzheimer’s disease.

    The findings suggest that vascular dysfunction could be an early driver in neurodegenerative disorders rather than being caused by neuronal damage.❞

    This association held true even in quite young patients!

    The study from Sweden looked at brain tissue from TBI patients (who had had to have brain tissue removed for medical reasons due to bleeding and swelling), and found that the (traumatic) changes to the vascular smooth muscle cells were associated with increased aggregation of amyloid-β.

    In terms of establishing cause and effect: since it could be safely concluded the amyloid-β had not caused the TBI (which all had external explanations such as “car crash” or such), it can be deduced that almost* certainly the TBI caused the amyloid-β aggregation.

    *because little to nothing in science is every truly certain. As in life in general, really; the difference is that scientists admit it!

    You may be wondering: what was the control? It would be a very generous group of citizens indeed who would volunteer bits of their brains that hadn’t needed removing. However, the answer is that the control brain bits came from a biobank, and were from uninjured patients with no history of TBI or neurodegenerative disorders, and who had died from systemic, unrelated causes. Having been dead for a matter of hours, and the fixation time for the brain bits from the living people taking long enough that everybody’s brain bits had been out of their respective living bodies for a similar length of time, this was deemed an acceptable, if imperfect, control.

    You can read the study in its entirety here; it is fascinating:

    Traumatic brain injury causes early aggregation of beta-amyloid peptides and NOTCH3 reduction in vascular smooth muscle cells of leptomeningeal arteries

    The practical take-away

    The practical take-away, of course, is: look after your brain

    Not just in the sense of eat fiber, get healthy fats, move more, get good sleep, stay intellectually stimulated, etc*, but also in the sense of “keep your brain physically safe”.

    Now, you may think that you already try not to get into car crashes, and perhaps you do not compete in contact sports, but do be aware that one of the leading causes of TBI in older people is, ignominiously, falling down.

    And if you think “that only happens to older/other people”, then be aware: there’s a first time for everything and you are not immune. With that in mind, do check out:

    Fall Special! ← the seasonal title notwithstanding, this is about not falling down in the first place, and being less injurable if you do fall down

    *This was a modest and vague list for brevity’s sake, so for much more detail, enjoy:
