Our Verdict

When comparing hazelnuts to pecans, we picked the hazelnuts.

Why?

In terms of macros, hazelnuts have more protein, carbs, and fiber, though the difference is not big in the latter two cases, and the glycemic indices are resultantly about the same. Meanwhile, pecans have a little more fat, but the fat is healthy in both cases. Everything taken into account, we’re calling it a tie on macros.

When it comes to vitamins, hazelnuts have more of vitamins B3, B5, B6, B7, B9, C, E, K, and choline, while pecans have more of vitamins A, B1, and B2. An easy win for hazelnuts here.

In the category of minerals, hazelnuts have more calcium, copper, iron, magnesium, manganese, phosphorus, and potassium, while pecans have more selenium and zinc. Another clear win for hazelnuts.

In short, enjoy either or both (unless you’re allergic, in which case, don’t), but hazelnuts are ultimately the more nutritionally dense of the two.

  • How To Grow New Brain Cells (At Any Age)

    How To Grow New Brain Cells (At Any Age)

    It was long believed that brain growth could not occur later in life, due to expending our innate stock of pluripotent stem cells. However, this was mostly based on rodent studies.

    Rodent studies are often used for brain research, because it’s difficult to find human volunteers willing to have their brains sliced thinly (so that the cells can be viewed under a microscope) at the end of the study.

    However, neurobiologist Dr. Maura Boldrini led a team that did a lot of research by means of autopsies on the hippocampi of (previously) healthy individuals ranging in age from 14 to 79.

    What she found is that while indeed the younger subjects did predictably have more young brain cells (neural progenitors and immature neurons), even the oldest subject, at the age of 79, had been producing new brain cells up until death.

    Read her landmark study: Human Hippocampal Neurogenesis Persists throughout Aging

    There was briefly a flurry of news articles about a study by Dr. Shawn Sorrels that refuted this, however, it later came to light that Dr. Sorrels had accidentally destroyed his own evidence during the cell-fixing process—these things happen; it’s just unfortunate the mistake was not picked up until after publication.

    A later study by a Dr. Elena Moreno-Jiménez fixed this flaw by using a shorter fixation time for the cell samples they wanted to look at, and found that there were tens of thousands of newly-made brain cells in samples from adults ranging from 43 to 87.

    Now, there was still a difference: the samples from the youngest adult had 30% more newly-made braincells than the 87-year-old, but given that previous science thought brain cell generation stopped in childhood, the fact that an 87-year-old was generating new brain cells 30% less quickly than a 43-year-old is hardly much of a criticism!

    As an aside: samples from patients with Alzheimer’s also had a 30% reduction in new braincell generation, compared to samples from patients of the same age without Alzheimer’s. But again… Even patients with Alzheimer’s were still growing some new brain cells.

    Read it for yourself: Adult hippocampal neurogenesis is abundant in neurologically healthy subjects and drops sharply in patients with Alzheimer’s disease

    Practical advice based on this information

    Since we can do neurogenesis at any age, but the rate does drop with age (and drops sharply in the case of Alzheimer’s disease), we need to:

    Feed your brain. The brain is the most calorie-consuming organ we have, by far, and it’s also made mostly of fat* and water. So, get plenty of healthy fats, and get plenty of water.

    *Fun fact: while depictions in fiction (and/or chemically preserved brains) may lead many to believe the brain has a rubbery consistency, the untreated brain being made of mostly fat and water gives it more of a blancmange-like consistency in reality. That thing is delicate and spatters easily. There’s a reason it’s kept cushioned inside the strongest structure of our body, far more protected than anything in our torso.

    Exercise. Specifically, exercise that gets your blood pumping. This (as our earlier-featured video today referenced) is one of the biggest things we can do to boost Brain-Derived Neurotrophic Factor, or BDNF.

    Here be science: Brain-Derived Neurotrophic Factor, Depression, and Physical Activity: Making the Neuroplastic Connection

    However, that’s not the only way to increase BDNF; another is to enjoy a diet rich in polyphenols. These can be found in, for example, berries, tea, coffee, and chocolate. Technically those last two are also botanically berries, but given how we usually consume them, and given how rich they are in polyphenols, they merit a special mention.

    See for example: Effects of nutritional interventions on BDNF concentrations in humans: a systematic review

    Some supplements can help neuron (re)growth too, so if you haven’t already, you might want to check out our previous main feature on lion’s mane mushroom, a supplement which does exactly that.

  • Atomic Habits – by James Clear

    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.

    James Clear’s Atomic Habits has become “the” go-to book about the power of habit-forming. And, there’s no shortage of competition out there, so that’s quite a statement. What makes this book stand out?

    A lot of books start by assuming you want to build habits. That can seem a fair assumption; after all, we picked up the book! But an introductory chapter really hammers home the idea in a way that makes it a lot more motivational:

    • Habits are the compound interest of productivity
    • This means that progress is not linear, but exponential
    • Habits can also be stacked, and thus become synergistic
    • The more positive habits you add incrementally, the easier they become because each thing is making your life easier/better

    For example:

    • It’s easier to save money if you’re in good health
    • It’s easier to sleep better if you do not have financial worries
    • It’s easier to build your relationship with your loved ones if you’re not tired

    …and so on.

    For many people this presents a Catch-22 problem! Clear instead presents it as an opportunity… Start wherever you like, but just start small, with some two-minute thing, and build from there.

    A lot of the book is given over to:

    • how to form effective habits (using his “Four Laws”)
    • how to build them into your life
    • how to handle mishaps
    • how to make sure your habits are working for you
    • how to see habits as part of your identity, and not just a goal to be checked off

    The last one is perhaps key—goals cease to be motivating once accomplished. Habits, on the other hand, keep spiralling upwards (if you guide them appropriately).

    There’s lots more we could say, but it’s a one-minute book review, so we’ll just close by saying:

    This book can help you to become the kind of person who genuinely gets a little better each day, and reaps the benefits over time.

  • We created a VR tool to test brain function. It could one day help diagnose dementia

    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.

    If you or a loved one have noticed changes in your memory or thinking as you’ve grown older, this could reflect typical changes that occur with ageing. In some cases though, it might suggest something more, such as the onset of dementia.

    The best thing to do if you have concerns is to make an appointment with your GP, who will probably run some tests. Assessment is important because if there is something more going on, early diagnosis can enable prompt access to the right interventions, supports and care.

    But current methods of dementia screening have limitations, and testing can be daunting for patients.

    Our research suggests virtual reality (VR) could be a useful cognitive screening tool, and mitigate some of the challenges associated with current testing methods, opening up the possibility it may one day play a role in dementia diagnosis.

    Where current testing is falling short

    If someone is worried about their memory and thinking, their GP might ask them to complete a series of quick tasks that check things like the ability to follow simple instructions, basic arithmetic, memory and orientation.

    These sorts of screening tools are really good at confirming cognitive problems that may already be very apparent. But commonly used screening tests are not always so good at detecting early and more subtle difficulties with memory and thinking, meaning such changes could be missed until they get worse.

    A clinical neuropsychological assessment is better equipped to detect early changes. This involves a comprehensive review of a patient’s personal and medical history, and detailed assessment of cognitive functions, including attention, language, memory, executive functioning, mood factors and more. However, this can be costly and the testing can take several hours.

    Testing is also somewhat removed from everyday experience, not directly tapping into activities of daily living.

    Enter virtual reality

    VR technology uses computer-generated environments to create immersive experiences that feel like real life. While VR is often used for entertainment, it has increasingly found applications in health care, including in rehabilitation and falls prevention.

    Using VR for cognitive screening is still a new area. VR-based cognitive tests generally create a scenario such as shopping at a supermarket or driving around a city to ascertain how a person would perform in these situations.

    Notably, they engage various senses and cognitive processes such as sight, sound and spatial awareness in immersive ways. All this may reveal subtle impairments which can be missed by standard methods.

    VR assessments are also often more engaging and enjoyable, potentially reducing anxiety for those who may feel uneasy in traditional testing environments, and improving compliance compared to standard assessments.

    Most studies of VR-based cognitive tests have explored their capacity to pick up impairments in spatial memory (the ability to remember where something is located and how to get there), and the results have been promising.

    Given VR’s potential for assisting with diagnosis of cognitive impairment and dementia remains largely untapped, our team developed an online computerised game (referred to as semi-immersive VR) to see how well a person can remember, recall and complete everyday tasks. In our VR game, which lasts about 20 minutes, the user role plays a waiter in a cafe and receives a score on their performance.

    To assess its potential, we enlisted more than 140 people to play the game and provide feedback. The results of this research are published across three recent papers.

    Testing our VR tool

    In our most recently published study, we wanted to verify the accuracy and sensitivity of our VR game to assess cognitive abilities.

    We compared our test to an existing screening tool (called the TICS-M) in more than 130 adults. We found our VR task was able to capture meaningful aspects of cognitive function, including recalling food items and spatial memory.

    We also found younger adults performed better in the game than older adults, which echoes the pattern commonly seen in regular memory tests.

    Adults of a range of ages tried our computerised game.

    In a separate study, we followed ten adults aged over 65 while they completed the game, and interviewed them afterwards. We wanted to understand how this group – who the tool would target – perceived the task.

    These seniors told us they found the game user-friendly and believed it was a promising tool for screening memory. They described the game as engaging and immersive, expressing enthusiasm to continue playing. They didn’t find the task created anxiety.

    For a third study, we spoke to seven health-care professionals about the tool. Overall they gave positive feedback, and noted its dynamic approach to age-old diagnostic challenges.

    However, they did flag some concerns and potential barriers to implementing this sort of tool. These included resource constraints in clinical practice (such as time and space to carry out the assessment) and whether it would be accessible for people with limited technological skills. There was also some scepticism about whether the tool would be an accurate method to assist with dementia diagnosis.

    While our initial research suggests this tool could be a promising way to assess cognitive performance, this is not the same as diagnosing dementia. To improve the test’s ability to accurately detect those who likely have dementia, we’ll need to make it more specific for that purpose, and carry out further research to validate its effectiveness.

    We’ll be conducting more testing of the game soon. Anyone interested in giving it a go to help with our research can register on our team’s website.The Conversation

  • Celery vs Cucumber – Which is Healthier?
  • 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.

  • The Coffee-Cortisol Connection, And Two Ways To Tweak It For Health

    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.

    Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:

    Enjoy it, but watch out!

    Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:

    • Drinking coffee caffeine first thing in the morning may not be ideal due to dehydration from overnight water loss.
    • Coffee caffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.
    • Coffee contains great antioxidants, which are of course beneficial for the health in general.
    • Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
    • Coffee caffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…
    • Elevated cortisol from early coffee caffeine drinking can build tolerance, leading to the need for more coffee caffeine over time.
    • It’s better, therefore, to defer drinking coffee caffeine until later in the morning when cortisol levels naturally drop.
    • All of this means that drinking coffee caffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe.
    • Hydrate first thing in the morning before consuming coffee caffeine to keep the body balanced and healthy.

    What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.

    In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.

    If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).

    Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).

  • Stick with It – by Dr. Sean Young

    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.

    Most of us know the theory when it comes to building new habits and/or replacing old ones, and maybe we even implement those ideas. So why is our success rate still not as high as we think it should be?

    Dr. Sean Young is here to do science to it!

    This book comes with advice and explanations that rely a lot less on “that sounds reasonable” and a lot more on “in this recent high-quality study, researchers found…”

    And, at 10almonds, we love that. We’re all for trying new things that sound reasonable in general… but we definitely prefer when there’s a stack of solid science to point to, and that’s the kind of thing we recommend!

    Dr. Young is big on using that science to find ways to trick our brains and get them working the way we want.

    Each chapter has lots of science, lots of explanations, and lots of actionable step-by-step advice.

    Bottom line: if you’re all over “Atomic Habits”, this one’s the science-based heavy-artillery for your practical neurohacking.
