I agree it won't happen in the very near future, but it will in the longer
term as the science becomes harder to ignore. At some point it must
inevitably become a problem, as Cordain acknowledges in the appendix of
The Paleo Diet. It took about 15-20 years for Atkins' diet to become
popular, and Atkins only figured out part of the puzzle. My guess is that
within another 20 years evolutionary nutrition and medicine will become
fairly widely known.
I don't eat a "hunter's diet" either. I mainly use the supermarket, though
I sometimes fish and sometimes get some hunted meat and wild fruits from
my brother-in-law. I noted the estimates of carrying capacity for hunter
gatherers because they are the only numbers I know of that can serve as
useful approximations of how many people could eat a supermarket
approximation of the Paleo diet. If anyone has any additional numbers I
would be pleased to see them.
Once the studies come out showing some people being essentially "cured" of
what were thought to be incurable diseases by dietary change, there will
be others scrambling to buy the foods that provided the "cure." There will
be lots of people who would rather die than dramatically change their
diets, just as there are many who continue to smoke despite the known
risks, but it won't take a major shift to make the already expensive Paleo
foods even more expensive.
I know a young woman who had physician-diagnosed Grave's disease
(hyperthyroidism)--a supposedly incurable disease--and had a total
remission of symptoms just by eliminating gluten foods from her diet. Her
specialist said she never has to see him again. When the studies start
showing improvements like this, people will gobble up the Paleo foods. The
problem is getting the studies funded, of course, but once a few studies
report results and get in the mass media, people will clamor for more
studies. It's hard to break into the mass media in a major way, of course,
but my guess is the correct science will eventually rise to the surface.
> I see a gradual change happening.
I agree, and as that change occurs the demand for Paleo (healthy) foods
will increase. Eventually increase in demand will outpace increase in
supply and the prices will rise--not for all foods, but for the Paleo
foods, which are much more difficult to mass produce than the modern foods.
> Assuming we are right in our beliefs about food, eventually the science
will catch up and the more offensive aspects of the modern diets will be
reduced. We can see that happening already, as KFC and MacDonalds try to
eliminate trans fats from their foods. A small step but maybe in the right
direction.
Yes, and the UK is ahead of the US in eliminating the worst food
ingredients, like trans fats. As I said, it may be possible to make
gradual changes to society's diet, aiming for a realistic goal. Shooting
for the foods of 1900 may be overreaching, but even if we could reduce or
eliminate just the most egregious foods and food ingredients of the last
50 years (like trans fats and loads of refined sweeteners) it would be a
major improvement. And perhaps American society could be encouraged to
replace gluten grains with gluten-free grains.
> Low fat diets are already on their way out, maybe because the science
behind them isn't there, or maybe just because of changing diet fads.
I wouldn't declare victory on that one quite yet. Dr. Dean Ornish has
given another boost to low-fat diets with his research and misguided
writings on his insanely low-fat diet. Ornish's work has been discussed in
these fora.
> Small changes can make a big difference in peoples' health. Cutting out
wheat and adding more fat made a big felt difference for me. I don't tell
people about paleo, I tell them how much relief I got from migraines and
painful joints after cutting out wheat. Small steps.
Same here. I don't even call it Paleo to the unitiated--it's too
offputting. I refer to it as ancestral, natural, wild, the original diet,
etc. But again, the biggest problem is not convincing other people, the
biggest problem is that when enough people are convinced this will
eventually have negative unintended consequences for Paleo dieters,
because there simply are not enough Paleo foods--not even in the
supermarkets--to feed even the industrialized nations, much less the total
world population, and Paleo foods are not as prone to mass production as
modern foods.
