In a way, Richtel got the best and worst of the publication date lottery. This book, which he’d obviously been working on for however long, was published in March 2020. Yes, that March 2020. So, it obviously got a huge boost in sales that launced it to bestseller status, and/but it doesn’t actually discuss COVID at all.

What it does discuss, is—as one might expect—the immune system. Or really, the immune systems, plural, several systems working alongside each other. How we got to have such, how our immune functions work, where all the various immune cells come from and what part they play. What pathogens can do to fight and/or confuse (or even co-opt) our immune response, and what modern medicine can do to counteract the pathogens’ anti-countermeasure countermeasures. And how it can still go wrong.

The “Four Lives” promised in the subtitle are stories, and Richtel explains the immune system through specific people’s specific battles. In particular, a friend of his who had quite a remarkable battle against cancer, which was of course terrible for him, but illustrative for us.

The style of the book is very readably journalistic. The author is a Pulitzer-winning NYT journalist, and not normally a science writer. Here at 10almonds, “we like big bibliographies and we cannot lie”, and we didn’t get to enjoy that in this case. The book contained no bibliography (nor appropriate inline citations, nor equivalent footnotes). Maybe a future addition will include this.

Bottom line: there’s a lot of “science for the lay reader” here. While the lack of references is a big oversight, the book does give a very good overview of what both sides (immune response and pathogenic invasion) bring to the battle of your body.

  • Statistical Models vs. Front-Line Workers: Who Knows Best How to Spend Opioid Settlement Cash?

    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.

    MOBILE, Ala. — In this Gulf Coast city, addiction medicine doctor Stephen Loyd announced at a January event what he called “a game-changer” for state and local governments spending billions of dollars in opioid settlement funds.

    The money, which comes from companies accused of aggressively marketing and distributing prescription painkillers, is meant to tackle the addiction crisis.

    But “how do you know that the money you’re spending is going to get you the result that you need?” asked Loyd, who was once hooked on prescription opioids himself and has become a nationally known figure since Michael Keaton played a character partially based on him in the Hulu series “Dopesick.”

    Loyd provided an answer: Use statistical modeling and artificial intelligence to simulate the opioid crisis, predict which programs will save the most lives, and help local officials decide the best use of settlement dollars.

    Loyd serves as the unpaid co-chair of the Helios Alliance, a group that hosted the event and is seeking $1.5 million to create such a simulation for Alabama.

    The state is set to receive more than $500 million from opioid settlements over nearly two decades. It announced $8.5 million in grants to various community groups in early February.

    Loyd’s audience that gray January morning included big players in Mobile, many of whom have known one another since their school days: the speaker pro tempore of Alabama’s legislature, representatives from the city and the local sheriff’s office, leaders from the nearby Poarch Band of Creek Indians, and dozens of addiction treatment providers and advocates for preventing youth addiction.

    Many of them were excited by the proposal, saying this type of data and statistics-driven approach could reduce personal and political biases and ensure settlement dollars are directed efficiently over the next decade.

    But some advocates and treatment providers say they don’t need a simulation to tell them where the needs are. They see it daily, when they try — and often fail — to get people medications, housing, and other basic services. They worry allocating $1.5 million for Helios prioritizes Big Tech promises for future success while shortchanging the urgent needs of people on the front lines today.

    “Data does not save lives. Numbers on a computer do not save lives,” said Lisa Teggart, who is in recovery and runs two sober living homes in Mobile. “I’m a person in the trenches,” she said after attending the Helios event. “We don’t have a clean-needle program. We don’t have enough treatment. … And it’s like, when is the money going to get to them?”

    The debate over whether to invest in technology or boots on the ground is likely to reverberate widely, as the Helios Alliance is in discussions to build similar models for other states, including West Virginia and Tennessee, where Loyd lives and leads the Opioid Abatement Council.

    New Predictive Promise?

    The Helios Alliance comprises nine nonprofit and for-profit organizations, with missions ranging from addiction treatment and mathematical modeling to artificial intelligence and marketing. As of mid-February, the alliance had received $750,000 to build its model for Alabama.

    The largest chunk — $500,000 — came from the Poarch Band of Creek Indians, whose tribal council voted unanimously to spend most of its opioid settlement dollars to date on the Helios initiative. A state agency chipped in an additional $250,000. Ten Alabama cities and some private foundations are considering investing as well.

    Stephen McNair, director of external affairs for Mobile, said the city has an obligation to use its settlement funds “in a way that is going to do the most good.” He hopes Helios will indicate how to do that, “instead of simply guessing.”

    Rayford Etherton, a former attorney and consultant from Mobile who created the Helios Alliance, said he is confident his team can “predict the likely success or failure of programs before a dollar is spent.”

    The Helios website features a similarly bold tagline: “Going Beyond Results to Predict Them.”

    To do this, the alliance uses system dynamics, a mathematical modeling technique developed at the Massachusetts Institute of Technology in the 1950s. The Helios model takes in local and national data about addiction services and the drug supply. Then it simulates the effects different policies or spending decisions can have on overdose deaths and addiction rates. New data can be added regularly and new simulations run anytime. The alliance uses that information to produce reports and recommendations.

    Etherton said it can help officials compare the impact of various approaches and identify unintended consequences. For example, would it save more lives to invest in housing or treatment? Will increasing police seizures of fentanyl decrease the number of people using it or will people switch to different substances?

    And yet, Etherton cautioned, the model is “not a crystal ball.” Data is often incomplete, and the real world can throw curveballs.

    Another limitation is that while Helios can suggest general strategies that might be most fruitful, it typically can’t predict, for instance, which of two rehab centers will be more effective. That decision would ultimately come down to individuals in charge of awarding contracts.

    Mathematical Models vs. On-the-Ground Experts

    To some people, what Helios is proposing sounds similar to a cheaper approach that 39 states — including Alabama — already have in place: opioid settlement councils that provide insights on how to best use the money. These are groups of people with expertise ranging from addiction medicine and law enforcement to social services and personal experience using drugs.

    Even in places without formal councils, treatment providers and recovery advocates say they can perform a similar function. Half a dozen advocates in Mobile told KFF Health News the city’s top need is low-cost housing for people who want to stop using drugs.

    “I wonder how much the results” from the Helios model “are going to look like what people on the ground doing this work have been saying for years,” said Chance Shaw, director of prevention for AIDS Alabama South and a person in recovery from opioid use disorder.

    But Loyd, the co-chair of the Helios board, sees the simulation platform as augmenting the work of opioid settlement councils, like the one he leads in Tennessee.

    Members of his council have been trying to decide how much money to invest in prevention efforts versus treatment, “but we just kind of look at it, and we guessed,” he said — the way it’s been done for decades. “I want to know specifically where to put the money and what I can expect from outcomes.”

    Jagpreet Chhatwal, an expert in mathematical modeling who directs the Institute for Technology Assessment at Massachusetts General Hospital, said models can reduce the risk of individual biases and blind spots shaping decisions.

    If the inputs and assumptions used to build the model are transparent, there’s an opportunity to instill greater trust in the distribution of this money, said Chhatwal, who is not affiliated with Helios. Yet if the model is proprietary — as Helios’ marketing materials suggest its product will be — that could erode public trust, he said.

    Etherton, of the Helios Alliance, told KFF Health News, “Everything we do will be available publicly for anyone who wants to look at it.”

    Urgent Needs vs. Long-Term Goals

    Helios’ pitch sounds simple: a small upfront cost to ensure sound future decision-making. “Spend 5% so you get the biggest impact with the other 95%,” Etherton said.

    To some people working in treatment and recovery, however, the upfront cost represents not just dollars, but opportunities lost for immediate help, be it someone who couldn’t find an open bed or get a ride to the pharmacy.

    “The urgency of being able to address those individual needs is vital,” said Pamela Sagness, executive director of the North Dakota Behavioral Health Division.

    Her department recently awarded $7 million in opioid settlement funds to programs that provide mental health and addiction treatment, housing, and syringe service programs because that’s what residents have been demanding, she said. An additional $52 million in grant requests — including an application from the Helios Alliance — went unfunded.

    Back in Mobile, advocates say they see the need for investment in direct services daily. More than 1,000 people visit the office of the nonprofit People Engaged in Recovery each month for recovery meetings, social events, and help connecting to social services. Yet the facility can’t afford to stock naloxone, a medication that can rapidly reverse overdoses.

    At the two recovery homes that Mobile resident Teggart runs, people can live in a drug-free space at a low cost. She manages 18 beds but said there’s enough demand to fill 100.

    Hannah Seale felt lucky to land one of those spots after leaving Mobile County jail last November.

    “All I had with me was one bag of clothes and some laundry detergent and one pair of shoes,” Seale said.

    Since arriving, she’s gotten her driver’s license, applied for food stamps, and attended intensive treatment. In late January, she was working two jobs and reconnecting with her 4- and 7-year-old daughters.

    After 17 years of drug use, the recovery home “is the one that’s worked for me,” she said.

  • Reversing Alzheimer’s – by Dr. Heather Sandison

    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 here is bold, isn’t it? But, if the studies so far are anything to go by, she is, indeed, reversing Alzheimer’s. By this we mean: her Alzheimer’s patients have enjoyed a measurable reversal of the symptoms of cognitive decline (this is not something that usually happens).

    The science here is actually new, and/but references are given aplenty, including Dr. Sandison’s own research and others—there’s a bibliography of several hundred papers, which we love to see.

    Dr. Sandison’s approach is of course multivector, but is far more lifestyle medicine than pills, with diet in particular playing a critical role. Indeed, it’s worth mentioning that she is a naturopathic doctor (not an MD), so that is her focus—though she’s had a lot of MDs looking in on her work too, as you may see in the book. She has found best results in a diet low in carbs, high in healthy fats—and it bears emphasizing, healthy ones. Many other factors are also built in, but this is a book review, not a book summary.

    Nor does the book look at diet in isolation; other aspects of lifestyle are also taken into account, as well as various medical pathways, and how to draw up a personalized plan to deal with those.

    The book is written with the general assumption that the reader is someone with increased Alzheimer’s risk wishing to reduce that risk, or the relative of someone with Alzheimer’s disease already. However, the information within is beneficial to all.

    The style is on the hard end of pop-science; it’s written for the lay reader, but will (appropriately enough) require active engagement to read effectively.

    Bottom line: if Alzheimer’s is something that affects or is likely to affect you (directly, or per a loved one), then this is a very good book to have read

  • An Underrated Tool Against Alzheimer’s

    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.

    Dementia in general, and Alzheimer’s in particular, affects a lot of people, and probably even more than the stats show, because some (estimated to be: about half) will go undiagnosed and thus unreported:

    Alzheimer’s: The Bad News And The Good

    At 10almonds, we often talk about brain health, whether from a nutrition standpoint or other lifestyle factors. For nutrition, by the way, check out:

    Brain Food? The Eyes Have It!

    Today we’ll be looking at some new science for an underrated tool:

    Bilingualism as protective factor

    It’s well-known that bilingualism offers brain benefits, but most people would be hard-pressed to name what, specifically, those brain benefits are.

    As doctors Kristina Coulter and Natalie Phillips found in a recent study, one of the measurable benefits may be a defense against generalized (i.e. not necessarily language-related) memory loss Alzheimer’s disease.

    Specifically,

    ❝We used surface-based morphometry methods to measure cortical thickness and volume of language-related and AD-related brain regions. We did not observe evidence of brain reserve in language-related regions.

    However, reduced hippocampal volume was observed for monolingual, but not bilingual, older adults with AD. Thus, bilingualism is hypothesized to contribute to reserve in the form of brain maintenance in the context of AD.❞

    Read in full: Bilinguals show evidence of brain maintenance in Alzheimer’s disease

    This is important, because while language is processed in various parts of the brain beyond the scope of this article, the hippocampi* are where memory is stored.

    *usually mentioned in the singular as “hippocampus”, but you have one on each side, unless some terrible accident or incident befell you.

    What this means in practical terms: these results suggest that being bilingual means we will retain more of our capacity for memory, even if we get Alzheimer’s disease, than people who are monolingual.

    Furthermore, while we’re talking practicality:

    ❝…our subsample may be characterized as mostly late bilinguals (i.e., learning an L2 after age 5), having moderate self-reported L2 ability, and relatively few participants reporting daily L2 use (33 out of 119)❞

    (L2 = second language)

    This is important, because it means you don’t have to have grown up speaking multiple languages, you don’t even have to speak it well, and you don’t have to be using your second language(s) on a daily basis, to enjoy benefits. Merely having them in your head appears to be sufficient to trigger the brain to go “oh, we need to boost and maintain the hippocampal volume”.

    We would hypothesize that using second language(s) regularly and/or speaking second language(s) well offers additional protection, and the data would support this if it weren’t for the fact that the sample sizes for daily and high-level speakers are a bit small to draw conclusions.

    But the important part is: simply knowing another language, including if you literally just learned it later in life, is already protective of hippocampal volume in the context of Alzheimer’s disease.

    Here’s a pop-science article about the study, that goes into it in more detail than we have room to here:

    Bilingualism linked to greater brain resilience in older adults

    Want to learn a new language?

    Here are some options where you can get going right away:

    Duolingo | Babbel | Lernu

    If you are thinking “sounds good, but learning a language is too much work”, then that is why we included that third option there. It’s specifically for one language, and that language is Esperanto, arguably the world’s easiest language and specifically designed to be super quick and easy to get good at. Also, it’s free!

  • Why You Don’t Need 8 Glasses Of Water Per Day

    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 idea that you need to drink eight glasses of water daily is a myth. For most people most of the time, this practice will not make your skin brighter, improve mental clarity, or boost energy levels. All that will happen as a result of drinking beyond your thirst, is that you’ll pee more.

    A self-regulating system

    Our kidneys regulate hydration by monitoring blood volume and salt levels. When blood becomes slightly saltier or its volume drops, such as through sweating, the kidneys absorb more water into the bloodstream. If needed, the body triggers thirst signals to encourage fluid intake.

    In most cases, you can rely on your body’s natural thirst cues to manage hydration. Thirst is a reliable indicator of when you need to drink water, making constant monitoring of water intake unnecessary for most people.

    There are some exceptions, though! Some people, such as those with kidney stones, especially older adults, or those with specific medical considerations and resultant advice from your doctor, may need to pay closer attention to their water intake.

    Nor does hydration have to be a matter of “drinking water”: many foods and drinks, such as fruit, coffee, soups, etc, contribute to your daily water intake and (because the body processes it more slowly) are often more hydrating than plain water (which can just pass straight through if you take more than a certain amount at once). If you listen to your body’s thirst signals, there’s no need to rigidly count eight glasses of water each day.

  • Widen the Window – by Dr. Elizabeth Stanley

    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.

    Firstly, about the title… That “window” that the author bids us “widen” is not a flowery metaphor, but rather, is referring to the window of exhibited resilience to stress/trauma; the “window” in question looks like an “inverted U” bell-curve on the graph.

    In other words: Dr. Stanley’s main premise here is that we respond best to moderate stress (i.e: in that window, the area under the curve!), but if there is too little or too much, we don’t do so well. The key, she argues, is widening that middle part (expanding the area under the curve) in which we perform optimally. That way, we can still function in a motivated fashion without extrinsic threats, and we also don’t collapse under the weight of overwhelm, either.

    The main strength of this book, however, lies in its practical exercises to accomplish that—and more.

    “And more”, because the subtitle also promised recovery from trauma, and the author delivers in that regard too. In this case, it’s about widening that same window, but this time to allow one’s parasympathetic nervous system to recognize that the traumatic event is behind us, and no longer a threat; we are safe now.

    Bottom line: if you would like to respond better to stress, and/or recover from trauma, this book is a very good tool.

  • Quinoa vs Couscous – Which is Healthier?

    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.

    Our Verdict

    When comparing quinoa to couscous, we picked the quinoa.

    Why?

    Firstly, quinoa is the least processed by far. Couscous, even if wholewheat, has by necessity been processed to make what is more or less the same general “stuff” as pasta. Now, the degree to which something has or has not been processed is a common indicator of healthiness, but not necessarily declarative. There are some processed foods that are healthy (e.g. many fermented products) and there are some unprocessed plant or animal products that can kill you (e.g. red meat’s health risks, or the wrong mushrooms). But in this case—quinoa vs couscous—it’s all borne out pretty much as expected.

    For the purposes of the following comparisons, we’ll be looking at uncooked/dry weights.

    In terms of macros, quinoa has a little more protein, slightly lower carbs, and several times the fiber. The amino acids making up quinoa’s protein are also much more varied.

    In the category of vitamins, quinoa has more of vitamins A, B1, B2, B6, and B9, while couscous boasts a little more of vitamins B3 and B5. Given the respective margins of difference, as well as the total vitamins contained, this category is an easy win for quinoa.

    When it comes to minerals, this one’s not even more clear. Quinoa has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Couscous, meanwhile has more of just one mineral: sodium. So, maybe not one you want more of.

    All in all, today’s is an easy pick: quinoa!
