Coffee, in moderation, is generally considered a healthful drink—speaking for the drink itself, at least! Because the same cannot be said for added sugar, various sorts of creamers, or iced caramelatte mocha frappucino dessert-style drinks:

The Bitter Truth About Coffee (or is it?)

Caffeine, too, broadly has more pros than cons (again, in moderation):

Caffeine: Cognitive Enhancer Or Brain-Wrecker?

Some people will be concerned about coffee and the heart. Assuming you don’t have a caffeine sensitivity (or you do but you drink decaf), it is heart-neutral in moderation, though there are some ways of preparing it that are better than others:

Make Your Coffee Heart-Healthier!

So, what about coffee and the gut?

The bacteria who enjoy a good coffee

Amongst our trillions of tiny friends, allies, associates, and enemies-on-the-inside, which ones like coffee, and what kind of coffee do they prefer?

A big (n=35,214) international multicohort analysis examined the associations between coffee consumption and very many different gut microbial species, and found:

115 species were positively associated with coffee consumption, mostly of the kind considered “friendly”, including ones often included in probiotic supplements, such as various Bifidobacterium and Lactobacillus species.

The kind that was most strongly associated with coffee consumption, however, was Lawsonibacter asaccharolyticus, a helpful little beast who converts chlorogenic acid (one of the main polyphenols in coffee) into caffeic acid, quinic acid, and various other metabolites that we can use.

More specifically: moderate coffee-drinkers, defined as drinking 1–3 cups per day, enjoyed a 300–400% increase in L. asaccharolyticus, while high coffee-drinkers (no, not that kind of high), defined as drinking 4 or more cups of coffee per day, enjoyed a 400–800% increase, compared to “never/rarely” coffee-drinkers (defined as drinking 2 or fewer cups per month).

Things that did not affect the outcome:

  • The coffee-making method—it seems the bacteria are not fussy in this regard, as espresso or brewed, and even instant, yielded the same gut microbiome benefits
  • The caffeine content—as both caffeinated and decaffeinated yielded the same gut microbiome benefits

Coffee consumption is associated with intestinal Lawsonibacter asaccharolyticus abundance and prevalence across multiple cohorts

Want to enjoy coffee, but not keen on the effects of caffeine or the taste of decaffeinated?

Taking l-theanine alongside coffee flattens the curve of caffeine metabolism, and means one can get the benefits without unwanted jitteriness:

    Cucumber Extract Beats Glucosamine & Chondroitin… At 1/135th Of The Dose?!

    Do you take glucosamine & chondroitin supplements for your bone-and-joint health?

    Or perhaps, like many, you take them intermittently because they mean taking several large tablets a day. Or maybe you don’t take them at all because they generally contain ingredients derived from shellfish?

    Cucumber extract has your back! (and your knees, and your hips, and…)

    It’s plant-derived (being from botanical cucumbers, not sea cucumbers, the aquatic animal!) and requires only 1/135th of the dosage to produce twice the benefits!

    Distilling the study to its absolute bare bones for your convenience:

    • Cucumber extract (10mg) was pitted against glucosamine & chondroitin (1350mg)
    • Cucumber extract performed around 50% better than G&C after 30 days
    • Cucumber extract performed more than 200% better than G&C after 180 days

    In conclusion, this study indicates that, in very lay terms:

    Cucumber extract blows glucosamine & chondroitin out of the water as a treatment and preventative for joint pain

  • Native Americans Have Shorter Life Spans. Better Health Care Isn’t the Only Answer.

    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.

    HISLE, S.D. — Katherine Goodlow is only 20, but she has experienced enough to know that people around her are dying too young.

    Goodlow, a member of the Lower Brule Sioux Tribe, said she’s lost six friends and acquaintances to suicide, two to car crashes, and one to appendicitis. Four of her relatives died in their 30s or 40s, from causes such as liver failure and covid-19, she said. And she recently lost a 1-year-old nephew.

    “Most Native American kids and young people lose their friends at a young age,” said Goodlow, who is considering becoming a mental health therapist to help her community. “So, I’d say we’re basically used to it, but it hurts worse every time we lose someone.”

    Native Americans tend to die much earlier than white Americans. Their median age at death was 14 years younger, according to an analysis of 2018-21 data from the Centers for Disease Control and Prevention

    The disparity is even greater in Goodlow’s home state. Indigenous South Dakotans who died between 2017 and 2021 had a median age of 58 — 22 years younger than white South Dakotans, according to state data.

    Donald Warne, a physician who is co-director of the Johns Hopkins Center for Indigenous Health and a member of the Oglala Sioux Tribe, can rattle off the most common medical conditions and accidents killing Native Americans.

    But what’s ultimately behind this low life expectancy, agree Warne and many other experts on Indigenous health, are social and economic forces. They argue that in addition to bolstering medical care and fully funding the Indian Health Service — which provides health care to Native Americans — there needs to be a greater investment in case management, parenting classes, and home visits.

    “It’s almost blasphemy for a physician to say,” but “the answer to addressing these things is not hiring more doctors and nurses,” Warne said. “The answer is having more community-based preventions.”

    The Indian Health Service funds several kinds of these programs, including community health worker initiatives, and efforts to increase access to fresh produce and traditional foods.

    Private insurers and state Medicaid programs, including South Dakota’s, are increasingly covering such services. But insurers don’t pay for all the services and aren’t reaching everyone who qualifies, according to Warne and the National Academy for State Health Policy.

    Warne pointed to Family Spirit, a program developed by the Johns Hopkins center to improve health outcomes for Indigenous mothers and children.

    Chelsea Randall, the director of maternal and child health at the Great Plains Tribal Leaders’ Health Board, said community health workers educate Native pregnant women and connect them with resources during home visits.

    “We can be with them throughout their pregnancy and be supportive and be the advocate for them,” said Randall, whose organization runs Family Spirit programs across seven reservations in the Dakotas, and in Rapid City, South Dakota.

    The community health workers help families until children turn 3, teaching parenting skills, family planning, drug abuse prevention, and stress management. They can also integrate the tribe’s culture by, for example, using their language or birthing traditions.

    The health board funds Family Spirit through a grant from the federal Health Resources and Services Administration, Randall said. Community health workers, she said, use some of that money to provide child car seats and to teach parents how to properly install them to counter high rates of fatal crashes.

    Other causes of early Native American deaths include homicide, drug overdoses, and chronic diseases, such as diabetes, Warne said. Native Americans also suffer a disproportionate number of infant and maternal deaths.

    The crisis is evident in the obituaries from the Sioux Funeral Home, which mostly serves Lakota people from the Pine Ridge Reservation and surrounding area. The funeral home’s Facebook page posts obituaries for older adults, but also for many infants, toddlers, teenagers, young adults, and middle-aged residents.

    Misty Merrival, who works at the funeral home, blames poor living conditions. Some community members struggle to find healthy food or afford heat in the winter, she said. They may live in homes with broken windows or that are crowded with extended family members. Some neighborhoods are strewn with trash, including intravenous needles and broken bottles.

    Seeing all these premature deaths has inspired Merrival to keep herself and her teenage daughter healthy by abstaining from drugs and driving safely. They also talk every day about how they’re feeling, as a suicide-prevention strategy.

    “We’ve made a promise to each other that we wouldn’t leave each other like that,” Merrival said.

    Many Native Americans live in small towns or on poor, rural reservations. But rurality alone doesn’t explain the gap in life expectancy. For example, white people in rural Montana live 17 years longer, on average, than Native Americans in the state, according to state data reported by Lee Enterprises newspapers.

    Many Indigenous people also face racism or personal trauma from child or sexual abuse and exposure to drugs or violence, Warne said. Some also deal with generational trauma from government programs and policies that broke up families and tried to suppress Native American culture.

    Even when programs are available, they’re not always accessible.

    Families without strong internet connections can’t easily make video appointments. Some lack cars or gas money to travel to clinics, and public transportation options are limited.

    Randall, the health board official, is pregnant and facing her own transportation struggles.

    It’s a three-hour round trip between her home in the town of Pine Ridge and her prenatal appointments in Rapid City. Randall has had to cancel several appointments when family members couldn’t lend their cars.

    Goodlow, the 20-year-old who has lost several loved ones, lives with seven other people in her mother’s two-bedroom house along a gravel road. Their tiny community on the Pine Ridge Reservation has homes and ranches but no stores.

    Goodlow attended several suicide-prevention presentations in high school. But the programs haven’t stopped the deaths. One friend recently killed herself after enduring the losses of her son, mother, best friend, and a niece and nephew.

    A month later, another friend died from a burst appendix at age 17, Goodlow said. The next day, Goodlow woke up to find one of her grandmother’s parakeets had died. That afternoon, she watched one of her dogs die after having seizures.

    “I thought it was like some sign,” Goodlow said. “I started crying and then I started thinking, ‘Why is this happening to me?’”

    Warne said the overall conditions on some reservations can create despair. But those same reservations, including Pine Ridge, also contain flourishing art scenes and language and cultural revitalization programs. And not all Native American communities are poor.

    Warne said federal, state, and tribal governments need to work together to improve life expectancy. He encourages tribes to negotiate contracts allowing them to manage their own health care facilities with federal dollars because that can open funding streams not available to the Indian Health Service.

    Katrina Fuller is the health director at Siċaŋġu Co, a nonprofit group on the Rosebud Reservation in South Dakota. Fuller, a member of the Rosebud Sioux Tribe, said the organization works toward “wicozani,” or the good way of life, which encompasses the physical, emotional, cultural, and financial health of the community.

    Siċaŋġu Co programs include bison restoration, youth development, a Lakota language immersion school, financial education, and food sovereignty initiatives.

    “Some people out here that are struggling, they have dreams, too. They just need the resources, the training, even the moral support,” Fuller said. “I had one person in our health coaching class tell me they just really needed someone to believe in them, that they could do it.”

  • What’s behind rising heart attack rates in younger adults

    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.

    Deaths from heart attacks have been in decline for decades, thanks to improved diagnosis and treatments. But, among younger adults under 50 and those from communities that have been marginalized, the trend has reversed. 

    More young people have suffered heart attacks each year since the 2000s—and the reasons why aren’t always clear. 

    Here’s what you need to know about heart attack trends in younger adults.

    Heart attack deaths began declining in the 1980s

    Heart disease has been a leading cause of death in the United States for more than a century, but rates have declined for decades as diagnosis and treatments improved. In the 1950s, half of all Americans who had heart attacks died, compared to one in eight today. 

    A 2023 study found that heart attack deaths declined 4 percent a year between 1999 and 2020. 

    The downward trend plateaued in the 2000s as heart attacks in young adults rose

    In 2012, the decline in heart disease deaths in the U.S. began to slow. A 2018 study revealed that a growing number of younger adults were suffering heart attacks, with women more affected than men. Additionally, younger adults made up one-third of heart attack hospitalizations, with one in five heart attack patients being under 40.

    The following year, data showed that heart attack rates among adults under 40 had increased steadily since 2006. Even more troubling, young patients were just as likely to die from heart attacks as patients more than a decade older. 

    Why are more younger adults having heart attacks?

    Heart attacks have historically been viewed as a condition that primarily affects older adults. So, what has changed in recent decades that puts younger adults at higher risk? 

    Higher rates of obesity, diabetes, and high blood pressure

    Several leading risk factors for heart attacks are rising among younger adults.
    Between 2009 and 2020, diabetes and obesity rates increased in Americans ages 20 to 44. 

    During the same period, hypertension, or high blood pressure, rates did not improve in younger adults overall and worsened in young Hispanic people. Notably, young Black adults had hypertension rates nearly twice as high as the general population. 

    Hypertension significantly increases the risk of heart attack and cardiovascular death in young adults.

    Increased substance use

    Substance use of all kinds increases the risk of cardiovascular issues, including heart attacks. A recent study found that cardiovascular deaths associated with substance use increased by 4 percent annually between 1999 and 2019. 

    The rise in substance use-related deaths has accelerated since 2012 and was particularly pronounced among women, younger adults (25-39), American Indians and Alaska Natives, and those in rural areas.

    Alcohol was linked to 65 percent of the deaths, but stimulants (like methamphetamine) and cannabis were the substances associated with the greatest increase in cardiovascular deaths during the study period. 

    Poor mental health

    Depression and poor mental health have been linked to cardiovascular issues in young adults. A 2023 study of nearly 600,000 adults under 50 found that depression and self-reported poor mental health are a risk factor for heart disease, regardless of socioeconomic or other cardiovascular risk factors. 

    Adults under 50 years consistently report mental health conditions at around twice the rate of older adults. Additionally, U.S. depression rates have trended up and reached an all-time high in 2023, when 17.8 percent of adults reported having depression. 

    Depression rates are rising fastest among women, adults under 44, and Black and Hispanic populations. 

    COVID-19

    COVID-19 can cause real, lasting damage to the heart, increasing the risk of certain cardiovascular diseases for up to a year after infection. Vaccination reduces the risk of heart attack and other cardiovascular events caused by COVID-19 infection.

    The first year of the pandemic marked the largest single-year spike in heart-related deaths in five years, including a 14 percent increase in heart attacks. In the second year of the pandemic, heart attacks in young adults increased by 30 percent. 

    Heart attack prevention 

    Not every heart attack is preventable, but everyone can take steps to reduce their risks. The American Heart Association recommends managing health conditions that increase heart disease risk, including diabetes, obesity, and high blood pressure. 

    Lifestyle changes like improving diet, reducing substance use, and increasing physical activity can also help reduce heart attack risk.

    How Are You, Really? The Free NHS Health Test

    We took this surprisingly incisive 10-minute test from the UK’s famous National Health Service—the test is part of the “Better Health” programme, a free-to-all (yes, even those from/in other countries) initiative aimed at keeping people healthy enough to have less need of medical attention.

    As one person who took the test wrote:

    ❝I didn’t expect that a government initiative would have me talking about how I need to keep myself going to be there for the people I love, let alone that a rapid-pace multiple-choice test would elicit these responses and give personalized replies in turn, but here we are❞

    It goes beyond covering the usual bases, in that it also looks at what’s most important to you, and why, and what might keep you from doing the things you want/need to do for your health, AND how those obstacles can be overcome.

    Pretty impressive for a 10-minute test!

  • The Inflammation Spectrum – by Dr. Will Cole

    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’ve previously reviewed Dr. Cole’s other book “Gut Feelings”, and now he’s back, this time to tackle inflammation.

    The focus here is on understanding what things trigger inflammation in your body—personally yours, not someone else’s—by something close to the usual elimination process yes, but he offers a way of sliding into it gently instead of simply quitting all the things and gradually adding everything back in.

    The next step he takes the reader through is eating not just to avoid triggering inflammation, but to actively combat it. From there, it should be possible for the reader to build an anti-inflammatory cookbook, that’s not only one’s own personal repertoire of cooking, but also specifically tailored to one’s own personal responses to different ingredients.

    The style of this book is very pop-science, helpful, walking-the-reader-by-the-hand through the processes involved. Dr. Cole wants to make everything as easy as possible.

    Bottom line: if your diet could use an anti-inflammatory revamp, this is a top-tier guidebook for doing just that.
