Oh, but I'm sure canola is perfectly safe.

> Crop Rotation

>  Following Canola or Mustard
>
> Research in Saskatchewan has shown that flax sometimes does poorly after canola or mustard. This is due to toxic compounds in mature canola and mustard plants and their seedling residues. However, research in Manitoba has shown that flax yields on canola stubble were generally not affected, although small reductions occurred in some years. The problem is most evident where straw and trash from the previous canola crop have not been adequately spread on the soil surface. Canola straw should, therefore, be spread uniformly, and spring volunteer seedlings should be controlled at an early stage in order to minimize possible toxic effects. Seeding into untilled canola stubble can also minimize the problem.

What exactly is your point here? You think canola oil is unsafe to eat?

I don't know---maybe you could explain whether it is.  I did find the

Is it the erucic acid that concerns you?

Not particularly.  There may be more than one thing wrong with it.  The
biggest question seems to be the antithyroid effects of glucosinolates.

The first sentence of the letter should've been a warning:
"Recently I bought a cooking oil that's new to our supermarkets..."

Not only that, but before that 90 day period, there was no history, no
books, no nothing. How did we get through a day?

Some of the claims are ludicrous. Although rape is a member of the brassica or mustard family, it is not the source of mustard gas used in chemical warfare.

Don't provide links like the .gov search results and expect most people to
spend the time reading all those things. Provide excerpts which support what
you're saying, along with links for those of us who want to read more.
Otherwise, your credibility is immediately suspect. You *may* have a
secretary, but that person is not in this newsgroup.

The significance of the pubmed link was that Mary G. Enig (co-author of
the Con-ola article) is a degreed research scientist.  The pubmed link
is a list of some of her published articles.

I'm not questioning the credibility of any of the articles. I'm saying that
expecting us to read them all is like writing a college paper with footnotes
saying "Some book - I forgot which", or "This book, and guess which page".

Wow.  The point of my last post to you was that people weren't supposed
to read all those papers.  Most of them have little to do with canola.
They were just supposed to see that she has published a lot of
peer-reviewed research and so is less likely to be a crackpot.  Get it?

Only one published study in recent ten years and nine published studies in
total is not very impressive.

So that's why arguably the most prestigious university in the world

open his parachute wide and then argued cogently his case based on
evidence. Go figure!  :=)          jack

If it takes 660 pages to bamboozle them into believing
in God, they're not that gullible.

The 660 pages being the Bible?
Well, if they actually read it.
Seems that America is the most religiously fundamentalist country in
the world, and when questioned, the most ignorant about the details of
their holy book. So I would say that Dawkin's theories about children
believing what parents or elders tell them without question for their
own physical safety and so they believe anything they are told is
pretty right. I'm so glad my parents shoved nothing down my throat,
except a healthy questioning of everything. What is it the Jesuits say
about "give me the child until he is seven and I will give you the
man"?  At least they were honest.       jack

No, the 660 pages being the book they flog at the bottom of
the rant at that URL.  _Does God Believe in Atheists_, by
John "Fallacy of Presuming the Conclusion" Blanchard.

>Well, if they actually read it.

The bible is a f.cking mess.  Nobody who has "actually read
it" as an entire work could come away believing any of it,
because it's internally inconsistent to a crippling degree.

And the KJ version is not an entire work in the first
place.  The Apocrypha, which were also "the word of God",
were edited out of it by men.  The stories of Jesus being
a serial killer in his youth are particularly interesting.

>Seems that America is the most religiously fundamentalist country in

Second to many muslim countries, unfortunately.  We may
have state-sponsored religion, but we haven't succumbed
to anything like Sharia quite yet.

Sounds like some sort of weird hostage exchange deal to me...  :-)

The Jesuits, at least here in the U.S., also have had a reputation for
turning out some of the best-educated converts from Catholicism to
atheism or agnosticism, so perhaps it all balances out.  Or maybe that's
what they're talking about in your quote above.

I think you're ok unless you are a pig who is eating massive quantities
of babassu and mandioca.  Even then, take your iodine and all will be
well.

This 'canola thing' is a prennial weed; popping up at regular intervals.
I have no doubt that its origins can be traced to the corn oil
industry/lobby in the USA.
The Snopes article de-bunks it thoroughly but lazy people come across the
mis-information and predictably push the 'big red button' without further
thought.
