Mammalian Infant Food Macronutrients ~ Especially Human

There have been two major stories in the IHC-News of late, a mega-Facebook thread that has raised the issue of PUFA in baby formulas, a minor altercation between moi and Matt Stone on Facebook about a study on "autistic rats", and quite a few conversations on this blog involving PUFA of late that has prompted this post.  It is a prelude to at least two posts on the issue to come:  (1) The Pete Evans / Paleo Way / WAPF-inspired / Nora Gedgaudas defended liver-based baby formula controversy, and (2) Tim Noakes' recommendations of "LCHF" for babies.

#LCHFollies ~ Is there a place for beer, wine, spirits in the Banting lifestyle?

You're kidding, right?

What?  This is a serious question?  Why yes it is!

I've got some things to say -- hopefully in the next week or so -- about Tim Noakes running afoul of the Health Professions Council in his country for advocating a woman wean her child onto a LCHF diet.  But I had a Twitter exchange of my own the past couple of days, in which I basically encouraged folks to hijack the #WeSupportTimNoakes hashtag.  This is being started to, well, support Noakes against his percieved persecution.  Said Twitter exchange took me to a podcast page with a sidebar image showing the Facebook post screenshot below, and leading me to this podcast:  Alcohol and the LCHF Diet: Can you drink when Banting?

For Real??
No ... not the Onion website!

The Frassetto High Carb Paleo Diet in Diabetics - Part II

Part I

U Masharani, P Sherchan, M Schloetter, S Stratford, A Xiao, A Sebastian, M Nolte Kennedy and L Frassetto

{Apologies in advance:  No idea if this is truly as scattered as I think it might be, but I'm currently working on a number of projects, including "real job" stuff.  So rather than hold this up for perfecting, I'm hitting the publish button!}

The Take-Aways, Such as they are ...

In this three week trial, researchers used food questionnaires to assess usual intake prior to the study.  
... on the basis of our intake questionnaire and food recall responses, we expected the parameters of the subjects on the ADA recommended diet to remain unchanged from baseline, but in fact they also improved reducing the differences observed with the two diets.
I'm going to go out on a limb and suggest that the baseline reporting was, as has been demonstrated many times, flawed and subject to under reporting.  Indeed, the fact that both groups lost weight despite being fed "weight maintaining" calories in the intervention, and a -- gasp! -- actual US Dietary Guidelines-compliant "low fat - high carb" diet indicates that ... well ... what would you say?  Probably, that they weren't eating what they claimed, and when this has been assessed in metabolic ward studies, the macros have come out decidedly higher in fat as a percent.  That's an educated guess.

Insulin Secretion in the Progression of Type 2 Diabetes ~ First/Early Phase

Random Bump:

There has been some discussion of diagnosing diabetes type going on in my comments of late and I thought this might be a good post to bump in response.  It's pretty specific, but contains links to some background blogging.

I think it would be safe to say that I'm of the belief -- and the scientific evidence seems overwhelming in support -- that peripheral insulin resistance is either non-existent or plays a minor role in T2 diabetes.  

Nonetheless, the concept of IR remains, but for the most part is diagnosed using a fasting HOMA-IR score based on fasting insulin and glucose levels.  This is considered a measure of hepatic IR, but even here appears to be a flawed measure.    The "swamped insulin receptor" model is flawed.  Not saying it doesn't perhaps play a role, but glucose uptake is not the first defect nor the main determinant of elevated circulating glucose.  

The WHO even classified Type 2 Diabetes as such (1999):
7.2 Type 2 (predominantly insulin resistance with relative insulin deficiency or predominantly an insulin secretory defect with/without insulin resistance)
There is much evidence for the latter, and the former?  Well, it seems the evidence points far more conclusively to relative insulin deficiency vs. any sort of receptor swamping dysfunctional clogged sink model.  

This is also why I believe LC will never "cure" T2, because the GSIS is the first thing to go with chronic carb restriction.  This is well known and why low carbers are told to "carb load" with 150 grams for several days before a standard OGTT.   Insulin does far more than regulate blood glucose levels, it should be a no brainer in my opinion to aim for NORMAL insulin signaling/glucose regulation where possible.

The Frassetto High Carb Paleo Diet in Diabetics - Part I

New Study!!!

Metabolic and physiologic effects from consuming a hunter-gatherer (Paleolithic)-type diet in type 2 diabetes

Why Frassetto Paleo?

The first thing I do when I see a new paleo diet study is try to find out WHAT the diet actually was.  So even before I got the full text, I saw the "group" author and the description of the ramped up diets and knew it was her brand of paleo.  Here's a summary from this post, which has links to individual posts I've done on the other various studies.

Ancestral Health Dishonesty ~ Phinney, the Osage and more Buffalo Feces!

Howdy all!  This one's been languishing in the draft bin for a bit as I hadn't had the time to round out the continuing saga of buffalo hunters.  It certainly belongs in the "I don't call it the Incestral Health Community for nothing" file!  As I was publishing up the Buffalo Roaming post the other day, "news" came across Jimmy Moore's Instagram feed that Stephen Phinney was unloading some ancestral dishonesty on the attendees of the CONvention of the American Society of Bariatric Physicians (or was it the Nutrition and Metabolism half of the event, who cares, same general schtick, over and over).  I include a screenshot of the slide here to confirm that this is the same slide I'd seen Phinney use before as you'll see here in a bit.  Essentially, this appears to be the same talk, different CONference.

Where the Buffalo Roam ...

 {If you came here from social media looking for the PaleoFX [ ... excuse me ... Paleo f(x) ]  related content, do a quick browser search on "Deer Play" to skip on down.}

Oh, give me a home where the buffalo roam
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day
Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day .....

I want to thank Nina Teicholz.  This is a serious thank you, although I doubt she'd take it that way.  But for her referencing shenanigans, I would have never had the slightest inclination to read W.W. Newcomb Jr.'s The Indians of Texas: From Prehistoric to Modern Times.   I'm not going to describe this dense book as a page turner, and Newcomb's language is of an era when his chapter titles were acceptable.  But none the less it's been quite informational.  It's also interesting to piece together with accounts from the northern plains.

Nutritional Ketosis is an Oxymoron

This is going to be a rather short post, and I'm not going to reference it.  I simply don't have time.  (As always, feel free to contest any claims you feel are erroneous in the comments.)  But something has been bothering me for a long time about the whole nutritional ketosis thing, or what I call NuttyK, and I just couldn't put my finger on it.   And then it hit me, as I was looking into the buffalo hunting thing ...

Humans likely do have a long history of being in ketosis for periods of time.  Ketosis ... as in the metabolic adaptation to starvation to preserve lean mass and reduce glucose consumption by the brain.  These humans were in prolonged periods of caloric deficit without a "need" to be ... in other words they weren't overweight dieters getting most of their energy from surplus stores.  They were in starvation ketosis.
