: And why are collards usually recommended over kale?

Terry, I have been asking that same question for a couple years. Someone on another forum forwarded my question to Dr. Fredric Frye. Here is his answer.

T.B

Quoted e-mail message to Dr Frye along with his reply.

> "Someone posed this question recently, "I'm wondering why some people

say
Kale should be in the occasional category since Kale and Collards are
the
same species of plant? Kale has a favourable Cal:phos ratio and a very
low
oxalate level. Collards do have a higher Cal:phos ratio then kale but
the
oxalate level in collards is extremely" high *relative* to kale. Both
are
goitrogens, so why is collard acceptable as a staple while kale is
relegated to "occasional"?

"An excellent question! I have recommended both for
herbivorous/folivorous lizards. Helen Benton (Columbus,
Ohio, who has about 70 iguanas and other assorted beasties)
has been feeding both with excellent results and no
nutrition-related disorders whatsoever".

" Depending upon their availability at your greengrocer, I
see no rationale for selecting one over the other. By the
way, the oxylate content of collards is still, in my opinion,
hardly worth a concern; ditto for the small amount of thio-
cyanate level in both as compared to white head cabbage."

Cheers,

Fredric
