I just came across this article where they talk about kale and broccoli and says that it is actually dangerous! I was shocked when reading it, but it seems like a serious article. Whart do you people think? Have anyone else here heard about this? Please read this article!:
The author appears to have made an addendum stating that it was a satiric piece meant to demonstrate how easily any food can be demonized.
Afterall, who could write, "At current rates of growth, by 2350, almost all the world’s cropland will be devoted to kale" with a straight face? I am fairly certain there is an XKCD comic for this...
EDIT: There it is.
Not to make this post a total waste, this year we have had numerous breaks in in the garden (I took the plunge and surrounded it with deer fence. Problem over). Rabbits and deer have always avoided collards and kale and cabbage and broccoli, even though they represent easily 50% of the garden (I plant about 100 collards every year, similar amts of kale). Ground hogs eat them but it is always juveniles, when they disperse in June, and I noticed that this year ground hog left on its own (of course, I chased him with a pitchfork or flooded or smoked his burrow a number of times, so it might not be only nutrition). I can grow turnips outside the fence and they don't get bothered much.
Now it is amazing to step into the garden and see the chicory gone, the chard gone, the beets gone, the squash whacked, the beans heavily damaged, the carrots damaged, and no brassica has been touched. And I have often wondered why. I wonder if it is because this area has extremely low soil iodine (it used to be "goiter Belt" before iodized salt), and wildlife act accordingly. The groundhog at least actually eats pounds per day when given the chance. It may also explain why deer and rabbits are often browsers, eating a bit of everything, possibly to avoid too much of a given toxin. It reminds me that I can eat my pound of collards a day in the winter, but it is prudent to eat a fork or so of seaweed.
