Teaching oneself new things is often the most difficult kind of bootstrapping, especially when one is unsure of such critical things as:

  • Where to begin? How, for that matter, do we find where to begin?
  • What can/should a learning journey look like?
  • What challenges should we expect, and how will we overcome them?

Hollins answers all of these questions and more. The greatest value of this book is perhaps in its clear presentation of concrete step-by-step instructions. Hollins gives illustrated examples too, but most importantly, he gives models that can be applied to any given type of learning.

The book also covers the most difficult problems most people face when trying to learn something by themselves, including:

  • Keeping oneself on-task (maintaining discipline)
  • Measuring progress (self-testing beyond memorization)
  • Keeping a fair pace of progress (avoiding plateaus)
  • How to know when one’s knowledge is sufficient or not (avoiding Dunning-Kruger Club)

All in all, if you’re looking to learn a new subject or skill, this could be a first step that saves you a lot of time later!

  • Heart Smarter for Women – by Dr. Jennifer Mieres

    Dr. Mieres takes us through understanding our own heart disease risks as individuals rather than as averages. As the title suggests, she does assume a female readership, so if you are a man and have no female loved ones, this might not be the book for you. But aside from that, she walks us through examining risk in the context of age, other health conditions, lifestyle factors, and so forth—including not turning a blind eye to factors that might intersect, such as for example if a physical condition reduces how much we can exercise, or if there’s some reason we can’t follow the usual gold standard of heart-healthy diet.

    On which note, she does offer dietary advice, including information around recipes, meal-planning, and what things to always have in stock, as well as what things matter the most when it comes to what and how we eat.

    It’s not all lifestyle medicine though; Dr. Mieres gives due attention to many of the medications available for heart health issues—and the pros and cons of these.

    The style of the book is very simple and readable pop-science, without undue jargon, and with a generous glossary. As with many books of this genre, it does rely on (presumably apocryphal) anecdotes, though an interesting choice for this book is that it keeps a standing cast of four recurring characters, each to represent a set of circumstances and illustrate how certain things can go differently for different people, with different things then being needed and/or possible. Hopefully, any given reader will find themself represented at least moderately well somewhere in or between these four characters.

    Bottom line: this is a very informative and accessible book, that demystifies a lot of common confusions around heart health.

  • 11 Minutes to Pain-Free Hips – by Melinda Wright

    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 hips don’t lie, what are yours saying to you? If what they’re saying to you sounds like a cry for help sometimes, this is the book to get you onto a better track.

    The hip is the largest joint in your body, and it bears a lot of weight. So it’s little wonder if sometimes they’d like a word with the boss. The question is: what will you do about it? Melinda Wright has suggestions to keep your hips—and you—happy.

    She spends the first couple of chapters introducing key concepts, and some anatomy and physiology that’ll be good to know.

    Then we’re into resistance stretching, basic hip exercises, all the way through to more advanced stuff. There are very clear photos for each. One thing that stands out about this book is each exercise is not just explained simply and clearly, but also offers “easing oneself in” exercises. After all, we’re not all at the same starting point.

    The book finishes off with some more holistic advice about chronic pain management, based on her personal experience with scoliosis, and some dietary tips to reduce joint pain and inflammation too.

    All in all, a very helpful book!

  • Ozempic Helps People Walk Further

    There’s often a catch-22 when it comes to exercise: it’s important for good health, and/but people with ill health usually cannot exercise much.

    A recent (published today, at time of writing, the 29th of March 2025, never let it be said we don’t bring you the very most up-to-date health science!) study by Dr. Neda Rasouli et al. has shown there is a possible way through that catch-22, depending on the nature of the illness.

    This study followed 792 people across 112 outpatient clinical trial sites in 20 countries in North America, Asia, and Europe, with type 2 diabetes and peripheral artery disease.

    What they found

    Patients taking semaglutide (specifically, 1mg Ozempic) enjoyed a 21% median increase in walking distance, as well as some bonus benefits, namely:

    • Weight reduction: the semaglutide group saw a greater reduction in body weight (–4.1 kg; P < 0 .0001)
    • HbA1c levels: semaglutide lowered HbA1c by 1 percentage point (P < 0.0001)
    • Blood pressure: systolic blood pressure decreased by 3.2 mmHg (P = 0.0042)

    You may be wondering what that “P =” means: it’s the probability of this occurring by random chance, on a scale from zero (impossible outcome) to 1 (unavoidable outcome).

    For example:

    “We hypothesized that singing the happy birthday song before tossing a coin would result in it landing on heads. We sang the happy birthday song and tossed the coin; it landed on heads (P = 0.5)”

    In science, generally speaking anything with a probability of under 0.05 (expressed as: “P < 0.05”) is considered a statistically significant result.

    All this to say, the cited figures of, for example, P < 0.0001, are very significant indeed.

    On which note, that 21% median increase in walking distance? P < 0.0004.

    As for side effects? Serious adverse events related to the drug occurred in 1% of the semaglutide group vs 2% in the placebo group. So, that seems quite safe indeed.

  • Human, Bird, or Dog Waste? Scientists Parsing Poop To Aid DC’s Forgotten River

    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.

    KFF Health News Peggy Girshman reporting fellow Jackie Fortiér joined a boat tour to spotlight a review of microbes in the Anacostia River, a step toward making the river healthier and swimmable. The story was featured on WAMU’s “Health Hub” on Feb. 26.

    On a bright October day, high schoolers from Francis L. Cardozo Education Campus piled into a boat on the Anacostia River in Washington, D.C. Most had never been on the water before.

    Their guide, Trey Sherard of the Anacostia Riverkeeper, started the tour with a well-rehearsed safety talk. The nonprofit advocates for the protection of the river.

    A boy with tousled black hair casually dipped his fingers in the water.

    “Don’t touch it!” Sherard yelled.

    Why was Sherard being so stern? Was it dangerously cold? Were there biting fish?

    Because of the sewage.

    “We get less sewage than we used to. Sewage is a code word for what?” Sherard asked the teenagers.

    “Poop!” one student piped up.

    “Human poop,” Sherard said. “Notice I didn’t say we get none. I said we get what? Less.”

    Tours like this are designed to get young people interested in the river’s ecology, but it’s a fine line to tread — interacting with the water can make people sick. Because of the health risks, swimming hasn’t been legal in the Anacostia for more than half a century. The polluted water can cause gastrointestinal and respiratory illnesses, as well as eye, nose, and skin infections.

    The river is the cleanest it’s been in years, according to environmental experts, but they still advise you not to take a dip in the Anacostia — not yet, at least.

    About 40 million people in the U.S. live in a community with a combined sewer system, where wastewater and stormwater flow through the same pipes. When pipe capacities are reached after heavy rains, the overflow sends raw wastewater into the rivers instead of to a treatment plant.

    Federal regulations, including sections of the Clean Water Act, require municipalities such as Washington to reduce at least 85% of this pollution or face steep fines.

    To achieve compliance, Washington launched a $2.6 billion infrastructure project in 2011. DC Water’s Clean Rivers Project will eventually build multiple miles-long underground storage basins to capture stormwater and wastewater and pump it to treatment plants once heavy rains have subsided.

    The Anacostia tunnel is the first of these storage basins to be completed. It can collect 190 million gallons of bacteria-laden wastewater for later treatment, said Moussa Wone, vice president of the Clean Rivers Project.

    Climate change is causing more intense rainstorms in Washington, so even after construction is complete in 2030, Wone said, untreated stormwater will be discharged into the river, though much less frequently.

    “On the Anacostia, we’re going to be reducing the frequency of overflows from 82 to two in an average year,” Wone said.

    But while the Anacostia sewershed covers 176 square miles, he noted, only 17% is in Washington.

    “The other 83% is outside the district,” Wone said. “We can do our part, but everybody else has to do their part also.”

    Upstream in Maryland’s Montgomery and Prince George’s counties, miles of sewer lines are in the process of being upgraded to divert raw sewage to a treatment plant instead of the river.

    The data shows that poop is a problem for river health — but knowing what kind of poop it is matters. Scientists monitor E. coli to indicate the presence of feces in river water, but since the bacteria live in the guts of most warm-blooded animals, the source is difficult to determine.

    “Is it human feces? Or is it deer? Is it gulls’? Is it dogs’?” said Amy Sapkota, a professor of environmental and occupational health at the University of Maryland.

    Bacterial levels can fluctuate across the river even without rainstorms. An Anacostia Riverkeeper report found that in 2023 just three of nine sites sampled along the Washington portion of the watershed had consistently low E. coli levels throughout the summer season.

    Sapkota is heading a new bacterial monitoring program measuring the amount of E. coli that different animal species deposit along the river.

    The team uses microbial source tracking to analyze samples of river water taken from different locations each month by volunteers. The molecular approach enables scientists to target specific gene sequences associated with fecal bacteria and determine whether the bacteria come from humans or wildlife. Microbial source tracking also measures fecal pollution levels by source.

    “We can quantify the levels of different bacterial targets that may be coming from a human fecal source or an animal fecal source,” Sapkota said.

    Her team expects to have preliminary results this year.

    The health risk to humans from river water will never be zero, Sapkota said, but based on her team’s research, smart city planning and retooled infrastructure could lessen the level of harmful bacteria in the water.

    “Let’s say that we’re finding that actually there’s a lot of deer fecal signatures in our results,” Sapkota said. “Maybe this points to the fact that we need more green buffers along the river that can help prevent fecal contaminants from wildlife from entering the river during stormwater events.”

    Washington is hoping to recoup some of the cost of building green spaces and other river cleanup. In January, the office of D.C. Attorney General Brian Schwalb filed a lawsuit seeking unspecified damages from the federal government over decades of alleged pollution of the Anacostia River.

    Brenda Lee Richardson, coordinator of the Anacostia Parks & Community Collaborative, said the efforts to cut down on trash and sewage are paying off. She sees a river on the mend, with more plant and animal life sprouting up.

    “The ecosystem seems a lot greener,” she said. “There’s stuff in the river now that wasn’t there before.”

    But any changes to the waterfront need to be done with residents of both sides of the river in mind, she said.

    “We want there to be some sense of equity as it relates to who has access,” she said. “When I look at who is recreating, it’s not people who look like me.”

    Richardson has lived for 40 years in Ward 8 — a predominantly Black area on the east side of the river whose residents are generally less affluent than those on the west side. She and her neighbors don’t consider the Anacostia a place to get out and play, she said.

    As the water quality slowly improves, Richardson said, she hopes the Anacostia’s reputation is also rehabilitated. Even if it’s not safe to swim in, Richardson enjoys boating trips like the one with the Anacostia Riverkeeper.

    “To see all those creatures along the way and the greenery. It was comforting,” she said. “So rather than take a pill to settle my nerves, I can just go down the river.”

  • Peach vs Passion Fruit – 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 peach to passion fruit, we picked the passion fruit.

    Why?

    It wasn’t close!

    In terms of macros, passion fruit has more than 2x the protein, 2x the carbs, and 7x the fiber. That’s a big difference!

    In the category of vitamins, peach has more of vitamins B1, B5, E, and K, while passion fruit has more of vitamins A, B2, B3, B6, B7, B9, C, and choline. Again, not close.

    When it comes to minerals, peach has more manganese and zinc, while passion fruit has more calcium, copper, iron, magnesium, phosphorus, potassium, and selenium—and most of those margins are “by multiples”, not just a fraction more. Again, a clear winner here.

    Adding up these three overwhelming wins for passion fruit makes for an obvious total win for passion fruit.

    As ever, enjoy both, but if you’re going to pick one, then one of these fruits is extra passionate about bringing you nutrients.

  • Antioxidant Matcha Snack Bars

    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 antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.

    You will need

    For the base:

    • ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
    • ⅔ cup chopped dates

    For the main part:

    • 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
    • ½ cup almond milk (or your preferred milk of any kind)
    • ½ cup cacao nibs
    • 2 tbsp lime juice
    • 1 tbsp matcha powder
    • 1 tbsp maple syrup (omit if you don’t care for sweetness)

    For the topping (optional):

    • 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
    • Spare cacao nibs, chopped nuts, or anything else you might want on there

    Method

    (we suggest you read everything at least once before doing anything)

    1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.

    2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.

    3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.

    4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.

    5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.

    6) Serve!

    Enjoy!
