U.S. Longevity Falling, Not Keeping Up With the Jones’s

From NPR:

The average life expectancy for Americans shortened by over seven months [in 2021], according to new data from the Centers for Disease Control and Prevention.

That decrease follows an already big decline of 1.8 years in 2020. As a result, the expected life span of someone born in the U.S. is now 76.4 years — the shortest it has been in nearly two decades.

But we still have the best healthcare system in the world, right? Not if you judge it by life expectancy. From Health System Tracker:

Life expectancy in the U.S. and peer countries generally increased from 1980-2019, but decreased in most countries in 2020 due to COVID-19. From 2020 to 2021, life expectancy at birth began to rebound in most comparable countries while it continued to decline in the U.S. The CDC estimates life expectancy at birth in the U.S. decreased to 76.1 years in 2021, down 2.7 years from 78.8 years in 2019 and down 0.9 years from 2020. The average life expectancy at birth among comparable countries was 82.4 years in 2021, down 0.2 years from 2019 and up 0.4 years from 2020.

Hiccups: What’s Your Favorite Cure?

I’ve written previously about how Paul Ingraham helped cure my patello-femoral pain syndrome.

More recently, Paul looked into hiccup cures because his father had an intractable case. What finally worked for dad? Breathing into a plastic bag.

Boosting blood CO2 (hypercapnia) by breathing in a PLASTIC bag. This one is quite plausible and is easy and safe to try. Hypercapnia definitely affects some kinds of hiccups. The story (from a smart source, a good “friend of PainSci”): “There’s an even easier way out of hiccups — at zero cost. Learned it from my uncle, who studied medicine in Brazil in the 50s. Anesthetized patients with hiccups were a pain, so they needed to get rid of it ASAP. Method: breathing in a PLASTIC bag, small enough for you to get to hypercapnia (get higher blood levels of CO2). You have to hold the bag REALLY tight around nose and mouth to prevent air from escaping, and if you have troubles with dizziness, it’s advisable to sit down for it. As soon as it gets uncomfortable, mostly after 4-6 breaths, you can stop, the hiccup will be gone. I don’t know what this does to the phrenic nerve, but it works 100%.”

Safety Note: Obviously there could be some danger with this method. If he’d had low O2 or was struggling for breath, we likely wouldn’t have dared. (On the other hand, if he’d been in that state, he would’ve been at the hospital.) But he was supervised, with no possibility of getting stuck, and a matter of only just a few breaths. Perhaps there was still some risk… but I think not treating those hiccups was also a risk.

I’ve never tried that method for my hiccups. My personal favorite home remedy is “drinking from the far side of the glass.” AKA, drinking water upside down. Watch this video of a good ol’ boy demonstrating the technique although I would aim for drinking at least 6-8 fl oz of water before quitting. Don’t ask me how it works; it may have something to do with the soft palate or diaphragm.

Leanne Morgan: The Problem With the Paleo Diet

I just spent an hour laughing at Leanne Morgan videos at YouTube. Her humor is not for young people, but instead for women over 40 who have children. I love her accent.

Did Grok Have Eating Utensils? No!

“Me Grok”

DailyMail has an interesting article that promotes eating with your hands instead of forks, knives, and spoons.

Those who are sticklers for etiquette should look away now.

That’s because we’ve all been dining the wrong way and should be eating with our hands, according to a psychologist.

Professor Charles Spence, from the University of Oxford, said giving up cutlery is the secret to enjoying food.

He says eating with our hands can ‘heighten the dining experience’ – even for meals like pasta and messy curries.

The professor also claims that hand-feeding improves food flavor and texture while having myriad health benefits.

Alcohol: Sometimes Less is More

Jameson’s in a hotel bar near Chicago

A few months ago I ran across a thoughtful article by Morris van de Camp titled Love Drinking Less. It’s well worth a read if your alcohol consumption is out of control or heading that way.

Alcohol is a two-edged sword. On the one hand it makes life fun and turns strangers into intimate friends in the course of an evening; on the other, it makes a person dysfunctional. Very dysfunctional. Productive time is lost, relationships are damaged, and health is harmed.

I cannot say that I’ve “struggled” with alcohol in the truest sense. I’ve never been arrested for drunk driving, and I’ve had no serious relationship trouble from drinking. All of my drinking has been in an appropriate time and place — but one drink inevitably would lead to another. I’d wind up accidently drunk when I really wanted a light buzz. I also found that when the time came up when I’d be free to drink, I looked a bit too much forward to it.

If you’re a tippler, this is the time of year to consider a “Dry January.” You may learn something about yourself. Be kind to your liver — you only have one.

Nearsightedness Isn’t as Benign as You Think

Steve Parker MD, paleobetic diet,
Should have spent more time outdoors

Myopia, aka nearsightedness, is extremely common and can start in childhood or young adults. I myself have had to wear glasses since ~age 9, when I was astonished to see individual blades of grass and leaves on trees. Myopia over time it can lead to early-onset cataract, retinal detachment, and glaucoma. MedPageToday has an eye-opening article on treatments that can prevent myopia progression and complications. For example:

Common evidence-based treatments that offer both statistically significant and clinically meaningful efficacies include daytime multifocal soft contact lenses (MFSCL), overnight orthokeratology (ortho-k), and topical low dose atropine (LDA). Novel spectacle lenses also showed a promising myopia-inhibiting effect, albeit with limited availability in U.S. at the current moment. On average, these options slow myopia progression by 30-70%compared to conventional single vision glasses or contacts. With properly selected early interventions, not only the development of myopia stabilizes at younger ages, the endpoint of the progression is also much lower, resulting in significantly lower risk of complications. Furthermore, with lower level of myopia at stabilization, many myopic patients could be good candidates for refractive surgery with given corneal thickness.

I get the impression from the article than treatments need to be started in childhood.

Black Tea Consumption Reduces Risk of Death by 10%

according to an article at Annals of Internal Medicine. The study was done in a U.K. population over decade of observation. The 10% or more reduction in all-cause mortality was seen at a habitual consumption level of two or more cups of black tea daily. Most prior similar studies I’ve seen focus on green tea.

Time-Restricted Eating: Better to Restrict Earlier or Later in the Feeding Window?

Chinese researchers reviewed the literature on time-restricted eating and metabolic effects on humans. I’m not paying $31.50 USD for the full text article, but here’s the abstract:

Time-restricted feeding (TRF), a feasible form of intermittent fasting, has been proven to benefit metabolic health in animal models and humans. TRF restricts the daily feeding window to 3 to 12 h for eating ad libitum, with fasting for the rest of the day. To our knowledge, specific guidance on the appropriate time period for eating during TRF has not yet been promoted. Therefore, the aim of the present review was to summarize the current literature on the effects of TRF with different eating windows in humans and compare their effects on metabolic health–related markers. Early TRF (which restricts food intake during the early period of the day) and delayed TRF (which restricts food intake during the later period of the day) studies have shown that both TRF regimens improve metabolic health in terms of reducing energy intake, decreasing body weight, improving insulin sensitivity, reducing blood pressure, and reducing oxidative stress. Differences between the consequences of early and delayed TRF were found, including differences in changes in blood lipid factors. These preliminary findings may help to provide guidance for choosing suitable eating windows during TRF. Future studies with rigorous designs and direct comparisons between the effects of TRF regimens with different eating windows on metabolic health markers are still needed.

Paleo Theory: Dietary Changes Over the Millenia and Effects on Human Health

Three Europe-based researchers have attempted to summarize what we know about dietary changes over the course of human and cultural evolution, and the effects on our health. Well worth a read if you have the time, intelligence, and interest in the paleo diet. A quote:

Perhaps the most significant aspect of the present concerns the relationship between nutrition and health. Increasingly, more and more people around the world are suffering from various diseases of civilization, from diet-related intolerances, and are suffering from malnutrition despite the wide range of food available. At least in Western countries, there are fewer and fewer people in recent decades who must perform strenuous physical labor, but they still eat as if they worked in heavy industry. In addition, the calories supplied from processed foods have a high energy density but provide hardly any fiber and micronutrients. The failure to adapt diet and caloric intake to predominantly sedentary lifestyles and lack of exercise has consequences, the roots of which today often lie in childhood. Nutrition today is about its quality. Food should predictively promote health and help avoid diseases. This is why countless food trends and concepts are promoted, such as the veggie boom, the paleo diet, volumetrics, the Mediterranean diet and superfoods. Healthy living means consistently decimating or eliminating risk factors. But far too often we end up eating highly processed fast-food dishes and are addicted to sugar. However, the medical effects of our current diet in the form of CNCDs [chronic non-communicable diseases, aka diseases of civilization] are much more extensive than the most common diseases such as diabetes, cardiovascular disease, and stroke, as well as caries, periodontal disease, and others. For example, the consumption of predominantly soft, highly processed food has made the teeth’s job of grinding food almost obsolete, with fatal consequences that have not really been recognized. Since we no longer abrade our teeth, like we do all other body tissues, they may be causing diseases whose causes remain unrecognized because we lack a view into the past.

How Long Do Hunter-Gatherers Sleep?

Paleobetic diet
Probably needs 8 hours a night, if not more. And why is the light on?!

From The Lancet Neurology:

Prospective epidemiological studies in industrial societies indicate that 7 h of sleep per night in people aged 18 years or older is optimum, with higher and lower amounts of sleep predicting a shorter lifespan. Humans living a hunter-gatherer lifestyle (eg, tribal groups) sleep for 6-8 h per night, with the longest sleep durations in winter. The prevalence of insomnia in hunter-gatherer populations is low (around 2%) compared with the prevalence of insomnia in industrial societies (around 10-30%). 

Fun fact: Adult horses only sleep for 3-5 hours per day. And in a herd, there’s usually one “standing watch” for predators while the others sleep.
