I'm on quite a few mailing lists, and I don't usually post an intro like
this, but what the heck. I've got a lot to say, so I might as well start
with an intro.
I've been vegetarian for 11 years, vegan for the last few of those years,
and mostly (75%+) raw for the last year. Well, up until this month. :)
After a great deal of reading (mostly on-line) over the past maybe 6
months, I've decided to start the transition from mostly raw foods vegan
to something more like paleo. It is (intentionally) a slow process.
I'm not buying anything non-paleo, slowly introducing meat and eggs into
my diet, and slowly finishing off food stocks that I have (mainly grains).
I figure this will give me some time to adjust, and also means that I
don't throw food away. Estimating the size of my pantry (compared to my
gut :), it will probably take me several more months before I'm eating
a diet that could reasonably be called paleo.
I am mainly interested in nutrition, with an emphasis on primary research.
I have been through graduate school, and am aiming towards medical school
right now, so I'm comfortable reading the real stuff. I've joined this
list as well as several other diet related lists mostly for the nutrition
science content.
I tend to lurk on most mailing lists. I'm often too busy to keep up
reading lists regularly, so by the time I get to it, other people have
usually already written what I would have said. Also, sometimes my
comments are very specific, so I will generally just reply to the author.
So, you may not hear many replies from me, but I'm still here.
At first I thought I was going to be unique in coming to paleo from
veganism, but from what I've read so far on this list many of you
have done the same. If people would like to comment about making that
transition I'd love to hear it. What worked? What didn't work?
I have a several more questions too:
Should I purchase the new edition of Neanderthin? (Ray and Troy,
obviously, should not be answering this question :) I'm not a big
fan of buying books, especially when more accurate and up-to-date
information is typically available on the web. For those of you that
read on-line, how helpful do you find your paper copy of Neanderthin
compared to, say, beyondveg.com, paleofood.com, MEDLINE, the american
journal of clinical nutrition web site, etc? The same question
goes for _Fats that Heal, Fats that Kill_, _Protein Power_, etc.
There are zillions of books on nutrition. I'm pretty happy that I
never bought _Diet for a New America_, and I'm wondering if I won't
feel the same way about any of these other books.
Paleo literature tends to advocate paleo diets for cancer prevention.
How is skin cancer from sunlight explained? I assume this kind
of cancer is not common among hunter-gatherers, despite the fact
that they spend so much time in the sun. However, I have never seen
literature in the field of dermatology that challenges the notion that
prolonged exposure to ultraviolet light increases risk of skin cancer.
As a long time sufferer of chronic psoriasis and psoriatic arthritis,
I'm very interested in research -- or even anecdotal accounts --
of dietary intervention for treatment of psoriasis. My research has
turned up nothing really conclusive (fish oil, maybe), but since it
is now believed that psoriasis is an auto-immune disease, I wonder
if a paleo diet might help -- or any other diet for that matter.
A question about fats: I think most sources agree (and recent
discussion here confirms) that a diet high in saturated fats is
not healthy (compared to, say, monounsaturated fats). So, why does
the paleo diet encourage eating foods such as suet, schmaltz, lard,
and coconut oil? A quick poke at the USDA database reveals:
coconut oil 86.5% saturated (!)
beef fat, tallow 49.8% saturated
Fat, mutton tallow 47.3% saturated
fat, chicken 29.8% saturated
olive oil 13.5% saturated, 73.7% monounsaturated
Strangely, the pork fat entries in the USDA database are not 100% fat.
For 100g servings, I find the following fat content:
Pork, fresh, backfat, raw 32.21g/88.69g fat 36% saturated
Pork, fresh, separable fat, raw 23.52g/67.7g fat 34% saturated
Pork, fresh, separable fat, cooked 24.49g/63.9g fat 38% saturated
I don't know why cooked pork fat would be only 63% fat, but if
we believe the USDA information it's still high in saturated fat
compared to the rest of its fat content. So, what am I missing here?
Why wouldn't it be better to eat olive oil instead of lard?
A related question: how does one acquire coconut oil? When I open
a coconut, I see a clear liquid (USDA calls this "coconut water"),
and a white flesh (USDA calls this "coconut meat, raw"). The flesh
can be blended, but I've never observed oil to separate out of it
(like it does with some nuts). Bottled coconut oil seems wasteful
and non-paleo to me; I'd rather just eat raw coconuts.
Is there a better online reference for nutrient information than
the USDA database? The USDA listings have many shortcomings (e.g.,
lack of trans fat info, lack of antinutrient info). The NDS is a
little out of my price range ($8500). I don't know of any other
nutrient databases.
Another question on the USDA database. Has anyone here successfully
downloaded the raw USDA data (in text or DBF format) and converted
it into a usable, searchable database? I have filemaker pro and
can load the .DBF files, but I'm not skilled enough with database
programs to convert the data to a usable form. I want to do more
complex searches than the USDA web site allows (for example, sort the
data by a nutrient, or determine the nutrition content of a recipe or
meal plan), so the limited search tools on the web are insufficient.
What constitutes a "balanced" variety of meats? What types or cuts
of meat should be avoided? What should be included?
More generally speaking, is it possible to eat a balanced, healthy
(paleo) diet without taking supplements? It's discouraging to hear
the Troy Gilchrist say that he takes a dried liver supplement _and_
a DHA supplement. I would like to get all my nutrition from whole
natural foods if possible.
For any of you in the san francisco bay area, what are some good
places to acquire wild game meats? I have found organic beef at a
local health food store, but nothing else.
Any specific comments about Coleman Natural beef?
(www.colemannatural.com) According to their web site, their cows
are fed from feedlot (doesn't say what feed though) for their last
100-120 days. I'm guessing this probably destroys any benefit that
the 12-18 months of grass feeding might have provided. Am I wrong?
What is better meat? (I only mention Coleman because it's easily
found in local stores.)
Is maple syrup paleo? How about carob? Nutritional yeast?
Whew! That was just the few questions I had on the top of my head.
I didn't expect this to be quite so long, so I think I'll stop now..
