Dear Mark: Wheat and Asthma, Minimalist Winter Shoes, High-Fat Rat
Cognition Study, and Sun Exposure Timing
Mark’s Daily Apple
by Mark Sisson: I
Will Never Go Back to the Broken Conventional Wisdom of My Past
edition of “Dear
Mark” runs the gamut. The topics will be somewhat familiar,
since I tackle wheat, minimalist shoes, high-fat diets in the news,
and vitamin D, but with interesting spins on each. First, I discuss
the link between wheat and asthma. Next, I do a somewhat exhaustive
search of the available winter minimalist shoe options, a topic
that I’ve never had cause to explore for myself. Since I do
this for you guys, though, I tried to help out. After that, it’s
my quick but (in my mind) pretty conclusive take on the latest article
to pin cognitive decline on a high-fat diet for a reader who’s
dealing with a similar condition herself (or himself; the gender
of the name “Jo” is somewhat ambiguous). And finally,
I discuss whether or not there’s a best time of day to obtain
vitamin D from the sun.
I love the
website and your books. I have been eating paleo for the past
4 months and notice a huge difference in my athletic performance
and general out look on life. I have suffered from asthma my entire
life. After eating a sandwich made with french bread (refined
wheat) or a plate of pasta (which is rarely now), I find my breathing
slightly labored even while sitting. Is there any research supporting
the removal of gluten and wheat help asthmatics?
I would love
to know you thoughts…
I think so,
yes. Something called baker’s asthma, which has been identified
at least the 1700s and is exactly as it sounds, is linked
to the ingestion (this time via the clouds of airborne flour to
which bakers are constantly exposed) of gliadins, the protein
subfractions that make up gluten.
also a related condition called wheat-dependent
exercise-induced anaphylaxis where wheat-related proteins make
it through the intestinal wall into the blood and cause an immune
response that manifests as an asthma attack. It’s “exercise-induced”
because exercise seems to speed up the rate at which the wheat
gliadins make it into the blood, but even those at rest had evidence
of an immune response to the gliadins.
also evidence of plain-old
wheat-induced asthma – no exercise necessary.
you’re on to something, Drew. You can keep experimenting if
you like, but I’d suggest just staying away from the stuff
myself! Good luck!
I’m very addicted to my Vibrams, and with this nor’easter
coming through I had to go back to my winter boots, and while
they do keep me dry and warm, I’m hating it!
through the site but didn’t find anything as far as some
type of minimalist shoe for winter? Any recommendations?
made a winter type shoe. I see they used to make one that kind
of looks like it would be helpful, but they don’t sell it
I share your
addiction. For folks who actually have real seasons with a real
winter, the minimalist winter shoe is something of a white whale
– an enigma hovering just out of reach, a product that you
know should exist but that you can never actually pin down. I’ve
never really looked into it for my own feet, since they rarely see
cold weather, but let’s see what’s out there, yeah?
First, a quick
glance at the minimalist wintery offerings from the well-known companies
Nothing meant for winter that I could see.
Life Frost Glove: waterproof, insulated, Vibram sole.
Road Hi and Off
Road Mid look to be decently protective options.
They’ve got an entire winter
boot collection for women, albeit a fairly small one.
Phoenix Boot: sheepskin lining, 5 mm Vibram sole, lighter and
more flexible sole as of 2012, roomy toebox (very important, in
my experience, for true barefoot feel), naturally water-resistant.
Now, how about
the shoe options that might not be officially minimalist but are
Moccasin now makes a full lineup of minimalist moccasins,
some of which are winter proof. They’ve been around for decades,
so they should be pretty high quality.
Shoes has a Troop
Boot. It’s not billed or promoted as minimalist, but as
from Birthday Shoes suggests, it can certainly be modified to become
an effective, minimalist winter boot. They’ve got
‘em in women’s, too.
an actual minimalist army boot out, as well – the Belleville
Minimalist Training Boot. Read the review.
