What you need to know

  • Myocarditis, or inflammation of the heart muscle, is most commonly caused by a viral infection like COVID-19, not by vaccination.
  • In line with previous research, a recent CDC study found no association between COVID-19 vaccination and sudden cardiac death in previously healthy young people.
  • A COVID-19 infection is much more likely to cause inflammation of the heart muscle than a COVID-19 vaccine, and those cases are typically more severe.

Since the approval of the first COVID-19 vaccines, anti-vaccine advocates have raised concerns about heart muscle inflammation, also called myocarditis, after vaccination to suggest that vaccines are unsafe. They’ve also used concerns about myocarditis to spread false claims that vaccines cause sudden deaths, which is not true.

Research has consistently shown that cases of myocarditis after vaccination are extremely rare and usually mild, and a new study from the CDC found no association between sudden cardiac death and COVID-19 vaccination in young adults.

Read on to learn more about myocarditis and what the latest research says about COVID-19 vaccine safety.

What is myocarditis?

Myocarditis is inflammation of the myocardium, or the middle muscular layer of the heart wall. This inflammation weakens the heart’s ability to pump blood. Symptoms may include fatigue, shortness of breath, chest pain, rapid or irregular heartbeat, and flu-like symptoms.

Myocarditis may resolve on its own. In rare cases, it may lead to stroke, heart failure, heart attack, or death.

What causes myocarditis?

Myocarditis is typically caused by a viral infection like COVID-19. Bacteria, parasites, fungi, chemicals, and certain medications can also cause myocarditis.

In very rare cases, some people develop myocarditis after receiving a COVID-19 vaccine, but these cases are usually mild and resolve on their own. In contrast, a COVID-19 infection is much more likely to cause myocarditis, and those cases are typically more severe.

Staying up to date on vaccines reduces your risk of developing myocarditis from a COVID-19 infection.

Are COVID-19 vaccines safe for young people?

Yes. COVID-19 vaccines have been rigorously tested and monitored over the past three years and have been determined to be safe for everyone 6 months and older. A recent CDC study found no association between COVID-19 vaccination and sudden cardiac death in previously healthy young adults.

The benefits of vaccination outweigh any potential risks. Staying up to date on COVID-19 vaccines reduces your risk of severe illness, hospitalization, death, long COVID, and COVID-19-related complications, such as myocarditis.

The CDC recommends people 65 and older and immunocompromised people receive an additional dose of the updated COVID-19 vaccine this spring—if at least four months have passed since they received a COVID-19 vaccine.

  • Ginger Does A Lot More Than You Think

    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.

    Ginger’s benefits go deep!

    You are doubtlessly already familiar with what ginger is, so let’s skip right into the science.

    The most relevant active compound in the ginger root is called gingerol, and people enjoy it not just for its taste, but also a stack of health reasons, such as:

    • For weight loss
    • Against nausea
    • Against inflammation
    • For cardiovascular health
    • Against neurodegeneration

    Quite a collection! So, what does the science say?

    For weight loss

    This one’s quite straightforward. It not only helps overall weight loss, but also specifically improves waist-hip ratio, which is a much more important indicator of health than BMI.

    Read: The effects of ginger intake on weight loss and metabolic profiles among overweight and obese subjects: a systematic review and meta-analysis of randomized controlled trials

    Against nausea & pain

    Ginger has proven its effectiveness in many high quality clinical trials, against general nausea, post-surgery nausea, chemotherapy-induced nausea, and pregnancy-related nausea.

    Source: Ginger on Human Health: A Comprehensive Systematic Review of 109 Randomized Controlled Trials

    However! While it very clearly has been shown to be beneficial in the majority of cases, there are some small studies that suggest it may not be safe to take close to the time of giving birth, or in people with a history of pregnancy loss, or unusual vaginal bleeding, or clotting disorders.

    See specifically: Ginger for nausea and vomiting of pregnancy

    As a side note on the topic of “trouble down there”, ginger has also been found to be as effective as Novafen (a combination drug of acetaminophen (Tylenol), caffeine, and ibuprofen), in the task of relieving menstrual pain:

    See: Effect of Ginger and Novafen on menstrual pain: A cross-over trial

    Against inflammation & pain

    Ginger has well-established anti-inflammatory (and, incidentally, which affects many of the same systems, antioxidant) effects. Let’s take a look at that first:

    Read: Effect of Ginger on Inflammatory Diseases

    Attentive readers will note that this means that ginger is not merely some nebulous anti-inflammatory agent. Rather, it also specifically helps alleviate delineable inflammatory diseases, ranging from colitis to Crohn’s, arthritis to lupus.

    We’ll be honest (we always are!), the benefits in this case are not necessarily life-changing, but they are a statistically significant improvement, and if you are living with one of those conditions, chances are you’ll be glad of even things described in scientific literature as “modestly efficacious”.

    What does “modestly efficacious” look like? Here are the numbers from a review of 593 patients’ results in clinical trials (against placebo):

    ❝Following ginger intake, a statistically significant pain reduction SMD = −0.30 ([95% CI: [(−0.50, −0.09)], P = 0.005]) with a low degree of inconsistency among trials (I2 = 27%), and a statistically significant reduction in disability SMD = −0.22 ([95% CI: ([−0.39, −0.04)]; P = 0.01; I2 = 0%]) were seen, both in favor of ginger.❞

    ~ Bartels et al.

    To de-mathify that:

    • Ginger reduced pain by 30%
    • Ginger reduced disability by 22%

    Read the source: Efficacy and safety of ginger in osteoarthritis patients: a meta-analysis of randomized placebo-controlled trials

    Because (in part) of the same signalling pathways, it also has benefits against cancer (and you’ll remember, it also reduces the symptoms of chemotherapy).

    See for example: Ginger’s Role in Prevention and Treatment of Gastrointestinal Cancer

    For cardiovascular health

    In this case, its benefits are mostly twofold:

    Against neurodegeneration

    This is in large part because it reduces inflammation, which we discussed earlier.

    But, not everything passes the blood-brain barrier, so it’s worth noting when something (like gingerol) does also have an effect on brain health as well as the rest of the body.

    You do not want inflammation in your brain; that is Bad™ and strongly associated with Alzheimer’s and Parkinson’s.

    As well as reducing neuroinflammation, ginger has other relevant mechanisms too:

    ❝Its bioactive compounds may improve neurological symptoms and pathological conditions by modulating cell death or cell survival signaling molecules.

    The cognitive enhancing effects of ginger might be partly explained via alteration of both the monoamine and the cholinergic systems in various brain areas.

    Moreover, ginger decreases the production of inflammatory related factors❞

    ~ Arcusa et al.

    Role of Ginger in the Prevention of Neurodegenerative Diseases

    How much to take?

    In most studies, doses of 1–3 grams/day were used.

    Where to get it?

    Your local supermarket, as a first port-of-call. Especially given the dose you want, it may be nicer for you to have a touch of sliced ginger root in your cooking, rather than taking 2–6 capsules per day to get the same dose.

    Obviously, this depends on your culinary preferences, and ginger certainly doesn’t go with everything!

    If you do want it as a supplement, here is an example product on Amazon, for your convenience.

  • Kiwi Fruit vs Pineapple – 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 kiwi fruit to pineapple, we picked the kiwi.

    Why?

    In terms of macros, they’re mostly quite comparable, being fruits made of mostly water, and a similar carb count (slightly different proportions of sugar types, but nothing that throws out the end result, and the GI is low for both). Technically kiwi has twice the protein, but they are fruits and “twice the protein” means “0.5g difference per 100g”. Aside from that, and more meaningfully, kiwi also has twice the fiber.

    When it comes to vitamins, kiwi has more of vitamins A, B9, C, E, K, and choline, while pineapple has more of vitamins B1, B2, B3, B5, and B6. This would be a marginal (6:5) win for kiwi, but kiwi’s margins of difference are greater per vitamin, including 72x more vitamin E (with a cupful giving 29% of the RDA, vs a cupful of pineapple giving 0.4% of the RDA) and 57x more vitamin K (with a cupful giving a day’s RDA, vs a cupful of pineapple giving a little under 2% of the RDA). So, this is a fair win for kiwi.

    In the category of minerals, things are clear: kiwi has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while pineapple has more manganese. An overwhelming win for kiwi.

    Looking at their respective anti-inflammatory powers, pineapple has its special bromelain enzymes, which is a point in its favour, but when it comes to actual polyphenols, the two fruits are quite balanced, with kiwi’s flavonoids vs pineapple’s lignans.

    Adding up the sections, it’s a clear win for kiwi—but pineapple is a very respectable fruit too (especially because of its bromelain content), so do enjoy both!

  • 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.

    Our Verdict

    When comparing almond butter to cashew butter, we picked the almond.

    Why?

    It’s not just our pro-almonds bias! And of course exact nutritional values may vary depending on the recipe, but we’re using the USDA’s standardized figures which should represent a reasonable average. Specifically, we’re looking at the USDA entries for “[Nut] butter, plain, without salt added”.

    In terms of macros, almond butter takes the lead immediately with nearly 2x the protein and over 3x the fiber. In contrast, cashew butter has 1.5x the carbs, and the two nut butters are approximately equal on fat. An easy win for almond butter so far.

    When it comes to vitamins, almond butter has more of vitamins A, B2, B3, B5, E, and choline, while cashew butter has more of vitamins B1, B6, and K. Thus, a 6:3 win for almond butter.

    In the category of minerals, things are closer, but almond butter has more calcium, magnesium, manganese, phosphorus, and potassium, while cashew butter has more copper, iron, zinc, and selenium. So, a 5:4 win for almond butter.

    In short, these three wins for almond butter add up to one total win for almond butter, unless you have a pressing reason to have different priorities in what you’re looking for in terms of nutrition.

    Enjoy both, of course! Unless you are allergic, in which case, please don’t.

  • Owning Your Weight – by Henri Marcoux

    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.

    A lot of diet books—which this isn’t—presuppose that the reader wants to lose weight, and varyingly encourage and shame the reader into trying to do so.

    Dr. Henri Marcoux takes a completely different approach.

    He starts by assuming we are—whether consciously or not—the weight we want to be, and looks at the various physical and psychological factors that influence us to such. Ranging from food poverty to eating our feelings to social factors and more, he bids us examine our relationship with food and eating—not just in the sense of mindful eating, but from multiple scientific angles too.

    From this, Dr. Marcoux gives us questions and suggestions to ensure that our relationship with food and eating is what we want it to be, for us.

    Much of the latter part of the book covers not just how to go about the requisite lifestyle changes… But also how to implement things in a way that sticks, and is a genuine pleasure to implement. If this sounds over-the-top, the truth is that it’s just because it honestly is a lower-stress way of living.

    Bottom line: if you want to gain or lose weight, there’s a good chance this book will help you. If you want to be happier and healthier at the weight you are, there’s a good chance this book will help you with that, too.
