Research / Sunshine and Human Health
« Last post by austinw90 on December 29, 2020, 05:04:43 PM »
One of the most overlooked health habits is getting regular sun exposure. Objectively speaking, this is probably the single most important factor after proper food, water, and sleep. Bright light exposure to our retinas regulates proper serotonin and melatonin expression - vital for mood and sleep. And, of course, allows us to synthesize vitmamin D in our skin, which is actually not a vitamin, but a seco-steroid hormone.

Our ancestors probably received 10x more sun exposure than we do nowadays.

Here's an article I've done summarizing and distilling all of the proven health benefits of sun exposure - or rather the proven consequences of a sun deficiency.

Included is a robust bibliography containing hundreds of peer-reviewed scientific studies of all types.

Note that that figure is for tallow from grain fed beef.  The figures I've seen for grass fed beef are in the 2:1 range.

Awesome, Warren Drew!! I'm getting 5 lbs. 100% grassfed tallow this Saturday at the farmers market! YEAH!!

Also, interesting to note from the first link, the only sources of EPA and DHA omega 3s are from fish oils. Looks like they're probably the best bet to source your omega 3s.....apparently all PUFA oils (polyunsaturated fatty acid oil), ie corn oil, canola oil, are pro inflamatory and are bad for your health. So basically omega 6 oils are pro inflam, and omega3s are anti inflam.

Hm, that is interesting! We do eat mackerel or saury at least twice a week, so that should do it. However, I can't imagine all Paleo man had access to fish, so maybe not that much of it is needed? That is also interesting about inflammatory oils!

P.S. I think I might have find a way to get mutton fat (actually lamb fat) at the farmers market!

ETA: I just found this great table that shows different fats and their omega ratio (scroll down for the table):

ETA2: I just found this as well about how much essential fatty acids we actually need:

Current reviews and textbooks call the omega-6 linoleic acid and the omega-3 alpha-linolenic acid “essential fatty acids” (EFA) and cite the EFA requirement as one to four percent of calories. Research suggests, however, that the omega-6 arachidonic acid (AA) and the omega-3 docosahexaenoic acid (DHA) are the only fatty acids that are truly essential. Eicosapentaenoic acid (EPA) occurs in fish products but is probably not a normal constituent of the mammalian body, and in excess it interferes with essential AA metabolism.

...For women who are seeking to conceive, pregnant, or lactating, the EFA requirement may be as high as one percent of calories. In other healthy adults, however, the requirement is infinitesimal if it exists at all. The best sources of EFAs are liver, butter, and egg yolks, especially from animals raised on pasture.

..An excess of linoleate from vegetable oil will interfere with the production of DHA while an excess of EPA from fish oil will interfere with the production and utilization of AA. EFAs are polyunsaturated fatty acids (PUFAs) that contribute to oxidative stress. Vitamin E and other antioxidant nutrients cannot fully protect against oxidative stress induced by dietary PUFAs. Therefore, the consumption of EFAs should be kept as close to the minimum requirement as is practical while still maintaining an appetizing and nutritious diet.

I checked the two that it said ARE essential, and they are both available in grass-fed meats, eggs (and dairy).
big thanks for your post

Research / Ketones stabilize brain function
« Last post by Warren Dew on May 21, 2020, 06:55:57 PM »
A couple of times recently, I've talked to smart people in my age range - I'm 60 - and they've remarked that they don't think they're as intelligent as they once were.  I have not noticed any degradation in myself.  This paper suggests that my switching to a ketogenic paleo diet a decade ago may be why.

"Large-scale life span neuroimaging datasets show functional communication between brain regions destabilizes with age, typically starting in the late 40s, and that destabilization correlates with poorer cognition and accelerates with insulin resistance. Targeted experiments show that this biomarker for brain aging is reliably modulated with consump- tion of different fuel sources: Glucose decreases, and ketones increase the stability of brain networks."

Food Journals / Cautionary tales #25
« Last post by Warren Dew on December 26, 2019, 12:30:49 AM »
Had another period of high chocolate consumption over most of this year.  The store I got the 100% chocolate from stopped selling it, and Ghirardelli released a 92% that's regularly available, so switching to the 92% may have something to do with it.  However, a job where I often felt the need to get caffeine from chocolate to stay up late or wake up in the morning probably didn't help either.  Weight again went up, to a maximum of about 158.

I've managed to get my sleep schedule under control, my chocolate consumption has dropped in the last week or two, and my weight is down to 154.  However, in a possibly unrelated event, I had a full fledged cold, which I can't trace to anything nonpaleo.  However, having the heat out in half of the home and thus constantly going back and forth between a 70F area and a 55F area, both dry, may have been part of the issue.

Had a very nice rib roast, with asparagus and melted lemon butter, for Christmas dinner; my wife, three preteens, and I finished about half of the roast.

I'm a software engineer.  I've never had to do more than say "no, thank you" or "I don't eat that stuff" more than a couple of times.  I have lots of coworkers who eat unhealthy snacks all day and are overweight, but they all realize it's unhealthy, so once they realize I have a diet I really stick to, they don't tend to push.
