Global rise of potential health hazards caused by blue light

-induced circadian disruptions in modern aging societies (Hatori et al., 2017)

While this article could’ve easily addressed the havoc wreaked on most animals (hibernating, migrating, reproducing, etc.) or even many plants by artificial light, the focus is on humans.

Mutual influence of sleep and circadian clocks on physiology and cognition

“The 24-hour sleep-wake cycle is one of the most prominent outputs of the circadian clock systems (Heyde et al., 2018)”

[Patron link]

Sleep disruption and circadian arrhythmia induce metabolic, cognitive, and immunological impairments. Is it causal? YES.

 

 

Sleep is highly conserved across the animal kingdom, since the dawn of time.

Interesting comparison: unlike hibernation or a coma, sleep is highly reversible. Lots of rebound regulation: lots of wakefulness makes you tired; lots of sleep leads to increased wakefulness.

Studies have shown improved memory performance after naps and extended sleep durations. Imo, you don’t need to go from 6 to 9.5 hours overnight, but keep that “9.5” on your radar.

Diet is easy, just eat like an adult. You can go 10 days without even eating! Try that with sleep. No, don’t try that. Most definitely incompatible with survival. Sleep deprivation impairs cognitive functions.

As a marker of health: cognitive function >>> how many reps you can do at the gym.

Circadian rhythms, sleep deprivation, and human performance

“Much of the current science on, and mathematical modeling of, dynamic changes in human performance within and between days is dominated by the two-process model of sleep-wake regulation, which posits a neurobiological drive for sleep that varies homeostatically (increasing as a saturating exponential during wakefulness and decreasing in a like manner during sleep), and a circadian process that neurobiologically modulates both the homeostatic drive for sleep and waking alertness and performance (Goel et al., 2013).”

[Patron link]

 

 

Acute and chronic sleep restriction degrade neurobehavioral functions, attention, cognitive speed, and memory. Strictly according to the studies (not your n=1), < 5.5 hours is bad, < 7 hours is suboptimal, and ~ 9.5 hours may be optimal. Seems like a lot; who has time to sleep 9.5 hours?!

Above image shows cerebral blood flow (orange) in the same person’s brain during a Psychomotor Vigilance Test performed in the morning and afternoon. Interestingly, most participants perform better in the afternoon and this is associated with more blood going to a different part of the brain.

“Sleep is a ubiquitous biological imperative that appears to be evolutionarily conserved across species.” Mandatory for optimal attention and cognitive performance.

Metabolism of starvation/fasting =/= low carb diet

The Biology of Starvation (intro)

The Biology of Starvation: Renal Gluconeogenesis

[Patron link]

One of the major [obvious] differences in metabolism between fasting and low carb dieting is nitrogen metabolism… because you’re eating protein on a low carb diet, not so much while fasting. During fasting/starvation your body tries to downregulate the urea cycle because you can’t really afford to be ‘wasting’ amino acids/protein. I bet you never thought about the muscle-sparing effect of fat-derived fuels like that!

 

 

“Glucose production in starvation” is important because you need to make all of it and reduce the use of it.

7 Worst Heart Health Sins (Page 20)

I read this on a magazine cover and my level of impending disappointment rapidly increased as I approached page 20. Aaaaand….

[Patron link]

It wasn’t horrible! Could use some tweaking, but hit a lot of important points and didn’t say “NO RED MEAT EVER.”

1/ You sneak a smoke.

DUH. Smoking cigarettes is the worst way to get your nicotine hit imaginable. Use a patch, chew nicotine gum, suck on a lozenge. Just. Don’t. Smoke. It also ages your skin faster.

 

 

2/ You skip your walk.

BOOM! We all know the power of a good walk, amirite? Get sunlight and fresh air, get off your butt as often as possible!

Poor sleep, “dietary disinhibition,” and weight gain

“Dietary disinhibition”

In school, the concept was taught like this: recruit a bunch of people and tell them it’s for a cookie taste-testing project. Give them a form with a bunch of questions about cookie quality (taste, texture, sweetness, etc.) and a plate of cookies.

[Patron link]

SWITCHAROO!

They aren’t there for a cookie taste-test. It turns out that some people experience “dietary disinhibition” wherein if they eat one cookie, they think something like “well, I’ve blown my diet for the day, so might as well just eat the whole plate of cookies” (actually, I’m pretty sure it’s way more complicated than that, but I learned it in a nutrition class, not a psychology class).

It’s not a lot of people — most would just take a bite and fill out the questionnaire — but it’s been replicated in enough settings that it’s probably a real phenomenon.

Activate #Nrf2, then optimize: Brussels sprouts

Hahaha What can’t you do, Nrf2?

Remember The Day Almonds Became Interesting? Namely, “the long series of  unlikely events that must occur in order for the bifidogenic effects of almonds to manifest.” Well, it happened again. Or the opposite.

[Patron link]

I’m not a huge fan of antioxidant supps for a variety of reasons, including but not limited to ATBC and CARET. There are certainly some exceptions to this, although your body can handle itself quite well under most circumstances.

I am, however, a pretty big fan of periodically doing things like activating #Nrf2, because anti-cancer. Advantage is that if there’s nothing going on, Nrf2 is degraded pretty quickly (can’t really say the same about antiox supps). If there is something going one, Nrf2 rallies the troops to swiftly restore balance: pathways pathways pathways -> DEAD CANCER CELLS.

 

IT DOESN’T GET ANY EASIER THAN THIS, FAM

 

One of the major ways Nrf2 gets it done is by inducing the synthesis of endogenous protective compounds like glutathione. Glutathione synthesis requires sulfury stuff, particularly (if it’s available), cysteine. Guess what?

 

 

Sulforaphane activates Nrf2 and breaks down to provide cysteine for glutathione synthesis. WEIRD COINCIDENCE, I KNOW RIGHT?

WHAT CAN ANY REMOTELY REASONABLE PERSON CONCLUDE FROM THIS?

Caffeine, large meals, and bright light in the evening induce circadian misalignment. That’s why these are better suited earlier in the day.

Caffeine reduces sleep pressure (which is supposed to start low in the morning and peak shortly after sunset) and delays melatonin onset (Burke et al., 2015). After dinner, make it a decaf or just pass.

 

Caffeine is an adenosine antagonist, and the accumulation of adenosine in the brain throughout the day is thought to be a chemical mediator of sleep pressure. Caffeine also delays and reduces melatonin, which increases your sleep needs, or at least time in bed/darkness.

The BROAD Study or Meat

Is eating meat necessary?  Optimal?

THE ANSWER MAY SURPRISE YOU

Hint: it’s more important to not eat processed refined junk foods.

 

Exhibit A. The BROAD study: a randomized controlled trial using a whole food plant-based diet in the community for obesity, ischaemic heart disease, or diabetes (Wright et al., 2017)

Tl;dr: it worked.

 

 

The longer version: it was a low-fat vegan diet supplemented with 50 ug B12 (methylcobalamin) daily.

 

Participants were advised to eat until satiation.

We placed no restriction on total energy intake.

Participants were asked to not count calories.”

If meat causes cancer…

Disclaimer: I’m meat-cancer agnostic.  *IF* meat causes cancer (and I don’t think it does), it happens extremely slowly and only at very high levels of intake: to get statistically significant risk ratios, researchers usually look to top vs. bottom quartiles, which is quite a large difference in intake.

Meat-cancer studies Tl;dr: some studies show positive associations, some neutral, and none are negative (ie, it’s unlikely meat prevents cancer).

That said, if meat does cause cancer, here is how it might happen:

1. The “Maybes:” AGEs, leucine/mTOR, methionine, etc., but only in combination with numbers 2 & 3.  Not by themselves.

2. Circadian arrhythmia and cancer: potential mechanisms

3. Most animal foods have a lot of linoleate 18:2n6 or at least a lot more n6 than n3 (grass-fed is usually a little better in this context).  More on this below.
