from seed oil scout's egg testing:
"The primary driver of high Omega-6 (linoleic acid) in chicken eggs is the feed. Conventional chickens are raised on a slurry of corn and soy—both crops that are high in unstable polyunsaturated fatty acids (PUFAs).
-Conventional Feed: A ratio of nearly 11:1 (Omega-6 to Omega-3).
-Soy-Free Feed: A ratio of approximately 4.5:1.
The Sunflower Swap: Some farms (Shirttail Creek) remove soy but replace it with sunflower oil or meal, which is also high in linoleic acid.
The Flax Hack: Other farms pump chickens full of flaxseed to artificially jack up the Omega-3 numbers on the label. "
Since your eggs may have more linoleic acid than ideal it is best to keep all your other sources low and your total as low as possible.
in texas, Ken's Henz are a great non soy non-gmo choice


in medicine, there is a saying: "don't just do something, stand there"
often observing, waiting, being patient and staying calm is the best and hardest course of action
there may be a time to act, but that time does not always have to be now


don't fear fructose!
as long as you are not consuming excessive calories compared to your energy demands, fructose does not produce harmful effects.
however, excess fructose above your caloric needs does get converted to bacterial endotoxins in the gut which damages multiple organs, specifically the liver
so the most important point in creating health, is balancing energy demands with the beneficial effects of carbohydrates

my kids have never had a bowl of cereal. they have eaten cereal even terrible ones but always dry and always in the setting of it being like "halloween candy".
even the concept of cereal for breakfast grosses them out since they are so used to homemade pancakes, muffins, eggs, bacon, sausage and filling food for breakfast.
if you start kids young with delicious foods and explain to them why we eat different breakfast from their friends they don't fight you and embrace good eating.
we tried saying "you can't have fruit loops" but it wasn't as effective as me letting them have fruit loops when on vacation and showing them that 2 hours later they were hungry and moody for them to understand our reasoning.
talking to kids like they are adults instead of just saying "no" is never as effective as helping the learn from experience, especially bad experiences.

i unplugged from all news several years ago. when at work i always find out about the newest thing and getting information by word of mouth is a wonderful filter.
i spend a lot of time reading books, scientific papers and using computers and technology but have become allergic to news alerts, latest thing podcasts, and twitter like feeds.
mostly on nostr I post and ghost and prefer content that is first principled and scientific or has stood the test of 5+ years of time.
almost all of the academic busy work that faculty deal with such as grant writing, paper writing, yearly performance review and peer review is made 1000 times easier with large language models and moonshot. K2 is a game changer.
once you get on a glp-1 you will be on it for life unless you also make significant lifestyle modifications.

when you play a greyscale game, your mind activates to fill in the color. it is also easy to put it down because it i less "addictive" due to lower visual stimulation.
my kids love puzzle games on @daylightco and it is fun to watch them team up to solve them.
embrace boredom.
sometimes it is exactly what your brain needs
our need for sleep and the importance of long amounts of uninterrupted sleep may be driven by our mitochondria
During wakefulness, your neurons fire constantly, consuming enormous amounts of ATP. This drives the electron transport chain (ETC) at maximum capacity, which creates two critical problems: energy depletion and oxidation
1. Energy depletion: ATP gets hydrolyzed to ADP and AMP. The resulting low ATP/ADP ratio is a direct metabolic stress signal. Adenosine (formed from these breakdown products) accumulates and is a well-established sleep pressure molecule.
When we sleep neuronal activity decreases, allowing the electron transport chain to operate at lower capacity and reducing oxidation production and allow the reduction (opposite of oxidation) to catch up
the mitochondrial quality control mechanisms (mitophagy, biogenesis, fission/fusion dynamics) actively repair damage and replace dysfunctional mitochondria at a greater rate during sleep.

it is widely accepted in veterinary medicine that many canine skin disorders are as a result of zinc deficiency and poor gut health. after treating any topic fungal or bacterial infections, most vets will suggest a probiotic supplemented with minerals to maintain high quality fur grown and skin health. very rarely do we see this offered in human medicine but it in fact clears up many skin issues though to be "autoimmune"

the basis of modern virology
in medicine it is always enlightening to find natural controls. the Amish population serve as a human control --- but from a genetic standpoint, chimps serve as a control as well.
chimps in captivity have an approximate 2% cancer incidence yet share 99% similar genetics as humans. either that 1% genetic difference accounts for all of the increased malignancies in humans or humans have done something to themselves that create all of the malignancies that plague our modern health.
many will say that we get cancers because we live longer but captive chimpanzees live twice as long (15+ years more) than wild chimps so their lack of cancer is eye opening.

People feel invigorated after an ice bath because cold receptors in your skin trigger sympathetic nervous system activation. Plasma norepinephrine and dopamine spike within seconds since your physiologic response is to "get out as fast as possible"
Then your pituitary gland pumps out beta-endorphins to bind opioid receptors to counteract the pain of the cold exposure (just like a runners high)
Vasoconstriction shunts blood to your core. When you exit, peripheral vasodilation creates a surge of oxygenated blood to your muscles and brain.
Your cognitive override of all these systems trying to get you out of the bath is fed by a later dopamine reward and your normal warm environment then feels like a luxury.


the concept of the "6 month dental health check and cleaning" is largely a construct of dental insurance coverage. it was created as part of a pepsodent tooth paste advertisement in the 1950s and then solidified by dental insurance.
when you sign up for a dental plan you are essentially prepaying for the teeth "cleaning". this is why if you are self pay they rarely ever call you to get your teeth cleaning since they know you won't want to pay for it if you haven't already prepaid via your employer plan.
there has never been any scientific backing to visiting a dentist twice a year. is it a good idea...maybe but also is like visiting a mechanic when you don't have an issue...


this viral control study is the best modern one that I have read. They purposely inoculated people with H3N2 and then compared the transmission in masks
vs no mask and unfortunately only one transmission event occurred. It was so hard to get people sick with H3N2 even when being quaranteened in the same room that they concluded that it must be the ventilation rather than then possibility that something might be wrong with the theory of contagion.
