Food for Life – by Dr. Tim Spector

This book is, as the author puts it, “an eater’s guide to food and nutrition”. Rather than telling us what to eat or not eat, he provides an overview of what the latest science has to say about various foods, and leaves us to make our own informed decisions.

He also stands firmly by the “personalized nutrition” idea that he introduced in his previous book which we reviewed the other day, and gives advice on what tests we might like to perform.

The writing style is accessible, without shying away from reference to hard science. Dr. Spector provides lots of information about key chemicals, genes, gut bacteria, and more—as well as simply providing a very enjoyable read along the way.

Bottom line: if you’d like a much better idea of what food is (and isn’t) doing what, this book is an invaluable resource.

  • 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.

  • Take Care Of Your Lymphatic System To Beat Cognitive Decline

    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.

    First of all, for any unfamiliar with the lymphatic system, it’s mostly the body’s clean-up system (as well as a big part of the body’s anticancer system).

    See: The Lymphatic System Against Cancer & More

    It may not be the most glamorous job, but it’s certainly an essential one.

    There’s no lymph in the brain, but…

    Because of the blood-brain barrier (BBB) that keeps the astonishingly sensitive brain as safe as it can from unwanted things, there are many aspects of our physiology that only happen inside the brain, or only happen outside of it, as the compounds in question may be too large to get through the BBB.

    The lymphatic system is, in and of itself, an entirely outside-of-the-brain affair. So, how does stuff get cleaned out from the brain (such as beta-amyloid and alpha-synuclein clearance, to avoid Alzheimer’s and Parkinson’s, respectively)?

    The glymphatic system (a portmanteau of glial cells doing the job of the lymphatic system) is the brain’s own cleanup crew, and we wrote about it here:

    How To Clean Your Brain (Glymphatic Health Primer)

    Why lymph still matters for the brain

    Although the glymphatic system is doing a (hopefully) fine job of scrubbing up the brain, if the lymphatic system isn’t working at least as well, then this becomes the equivalent of what would happen if you at home were very attentive to taking the trash out, but the garbage disposal crews stopped doing their job, or did it much less well than they need to. Soon, you’d end up with a mountain of trash at home, even though you were doing your part correctly.

    In short: the glymphatic system needs to pass the waste on somewhere, and the lymphatic system is its go-to.

    You may be wondering about the role of blood in all of this, and the answer is that no part of any of the above systems can do its job without adequate oxygenation, and our blood also assists in the transport of things removed—which is one of the reasons why there are blood-based Alzheimer’s tests that can be done; they measure certain markers of neurodegeneration that become present in the blood having left the brain:

    Early Dementia Screening From Your Blood & More ← the “and more” is actually quite interesting, but it’s the blood we’re interested in for this section

    What can be done about it

    Our first two links up above, about the lymphatic and glymphatic systems, respectively, also tell how to look after each of them, but we’ll mention a few salient pointers here.

    For the lymphatic system:

    • do lymphatic massage
    • exercise, with a focus on maximizing movement
    • eat an anti-inflammatory diet

    For the glymphatic system:

    • do vagal massage (Vagal! Not vaginal, which will not help! Or rather: it won’t help the glymphatic system, anyway)
    • exercise, and/but also rest well (good quality sleep)
    • eat omega-3 fatty acids

    For more details and suggestions on each though, do check out:

    Lymphatic health primer | Glymphatic health primer

    How this was discovered

    Until as recently as 2014, it was not known that there was any part of the lymphatic system around the brain, waiting to take things from the glymphatic system. Since then, research has slowly been done about the relationship between the two, how things work, and what affects what and how.

    Most recently (the study was published two days ago, at time of writing this) it was discovered that, in mice at least, improving lymphatic function just outside of the brain (the meningeal lymphatic vessels, responsible for draining waste from the brain) improves memory.

    Aged mice who underwent a process that rejuvenated the meningeal lymphatic vessels, performed better in memory tests afterwards.

    How this worked, step-by-step:

    • The mice were given a special protein that rejuvenated the meningeal lymphatic vessels¹
    • The lymphatic vessels were then able to do their job better
    • This meant that the glial cells of the glymphatic system were no longer drowning in excess stuff
    • This reduced levels of a protein that says “help, too much stuff!” and starts inhibiting everything it can to try to cope²
    • This meant that neural activity was no longer being suppressed, and memory improved

    Technical bits for those who want it:

    ¹ We’re not being secretive about what this special protein was; it’s just that the special protein is called adeno-associated virus 1 cytomegalovirus murine vascular endothelial growth factor C, or “AAV1-CMV-mVEGF-C” for short, so for readability, “a special protein” does the job. Suffice it to say, a) you can’t exactly buy AAV1-CMV-mVEGF-C on Amazon, and b) you wouldn’t want it anyway, you’d want its close cousin AAV1-CMV-hVEGF-C (“m” for murine, i.e. mousey, vs “h” for human)

    ² This one’s just called interleukin-6 (IL-6); perhaps you’ve heard of interleukin; we’ve mentioned it sometimes before.

    You can read the paper in its entirety here; if you don’t mind reading very technical stuff, it is very interesting:

  • 6 Kinds Of Drinks That Hasten 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.

    Dr. William Li, most well-known for his diabetes expertise (remember that there are clear associations between diabetes and dementia), discusses drinks you might want to skip:

    Here’s to your good health

    The 6 kinds of drink are:

    • Alcohol which is bad for pretty much everything and this is no exception. Can cause a deficiency of thiamine, brain-shrinking, neuroinflammation, oxidative stress, and resultant neuron damage.
    • Soda / diet soda, the former of which is bad for the diabetes-dementia connection, and the latter of which is also usually (depends on the sweetener) harmful to the gut and thus the gut-brain connection.
    • Fruit juices, especially if processed, as the high sugar and zero or nearly-zero fiber can lead to insulin resistance, affecting the brain’s energy processing. In particular, fruit juice drinks sweetened with high-fructose corn syrup (HFCS) can accumulated as fat in the brain (due to how the body processes fructose in the absence of fiber to slow it down), impacting cognition.
    • Energy drinks, being basically the same as soda / diet soda, just now with added caffeine too.
    • [Caffeinated] late-night coffee, can (shocking nobody) disrupt sleep, and chronic sleep deprivation contributes to the build-up of harmful brain plaques.
    • Sports drinks, which (unless you’re super-sure about everything on the label; there are some good sports drinks out there) often contain HFCS in the US, along with various other additives that may not always be great for you. Also, the sodium content of electrolyte drinks are fine if you genuinely are actively sweating it out, but otherwise, can lead to high blood pressure, which is itself a dementia risk factor.

    Better options include:

    • decaffeinated coffee (or coffee enjoyed in the early afternoon)
    • green tea
    • turmeric-based drinks

    Dr. Li mentions turmeric milk drinks, but unfermented dairy is generally inflammatory, so better to make it kefir (fermented milk drink) or plant-based. Or just have a turmeric tea; that works too.

    Dr. Li also mentions berry smoothies, which are not nearly as bad as fruit juice, but still not as good as eating whole berries.

    First, what this is not: it’s not a cookbook. There are recipes, more than a hundred if we consider such things as “barbecue sauce” as a standalone recipe, and if we overlook such things as how “perfect hot oatmeal” is followed on the next page by a recipe for “perfect hot oatmeal with berries”.

    However, as we say, it’s not a cookbook; it’s first and foremost an educational text on the topic of nutrition.

    Here we will learn about good eating for general health, which foods are natural appetite-suppressants, which foods reduce our body’s absorption of sugars from foods (not merely slowing, but flushing them away so they cannot be absorbed at all), and which foods actually boost metabolism for a few hours after the meal.

    Dr. Barnard also talks about some foods that are more healthy, or less healthy, than popularly believed, and how to use all this information to craft a good, optimized, dietary plan for you.

    Bottom line: there’s a lot of good information here, and the recipes are simply a bonus.

  • Younger – by Dr. Sara Gottfried

    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.

    Does this do the things it says in the subtitle? In honestly, not really, no, but what it does do (if implemented) is modify your gene expression, slow aging, and extend healthspan. Which is all good stuff, even if it’s not the snappy SEO-oriented keywords in the subtitle.

    A lot of the book pertains to turning certain genes (e.g. SIRT1, mTOR, VDR, APOE4, etc) on or off per what is sensible in each case, noting that while genes are relatively fixed (technically they can be changed, but the science is young and we can’t do much yet), gene expression is something we can control quite a bit. And while it may be unsettling to have the loaded gun that is the APOE4 gene being held against your head, at the end of the day there are things we can do that influence whether the trigger gets pulled, and when. Same goes for other undesirable genes, and also for the desirable ones that are useless if they never actually get expressed.

    She offers (contained within the book, not as an upsell) a 7-week program that aims to set the reader up with good healthy habits to do just that and thus help keep age-related maladies at bay, and if we slip up, perhaps later in the year or so, we can always recommence the program.

    The advice is also just good health advice, even without taking gene expression into account, because there are a stack of benefits to each of the things in her protocol.

    The style is personable without being padded with fluff, accessible without dumbing down, and information-dense without being a challenging read. The formatting helps a lot also; a clear instructional layout is a lot better than a wall of text.

    Bottom line: if you’d like to tweak your genes for healthy longevity, this book can help you do just that!

  • Cucumber vs Lychee – 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 cucumber to lychee, we picked the lychee.

    Why?

    In terms of macros, the lychee has more carbs and more fiber, but both are low glycemic index foods. Functionally a tie, though we could consider it a nominal win for cucumber.

    In the category of vitamins, cucumber has more of vitamins A, B1, B5, and K, while lychee has more of vitamins B2, B3, B6, B9, C, E, and choline. In particular, cucumber has a lot more vitamin K and lychee has a lot more vitamin C. Nevertheless, in terms of overall vitamin coverage, lychee is the clear winner here.

    Looking at minerals, cucumber has more calcium, magnesium, manganese, and zinc, while lychee has more copper (especially rich in this), iron, phosphorus, potassium, and selenium. Another clear win for lychee.

    Both have an abundance of anti-inflammatory polyphenols, but we could find no strong argument for one being better than the other in this category, just different.

    In short, both are fine options, but the more nutritionally dense is the lychee, so that’s our choice!
