Too much fertilizer makes vegetables poisonous?

Lessee ... massive overfertilization, cold conditions and low light levels.
Nope ... none of those conditions prevail in my garden.
When people push N in an imbalanced manner in order to force poundage of
green veggies, they are not trying to grow _healthy_ veggies anyways; they
are trying to grow _lots_ of veggies without any but statutory regard for
the healthfulness of them. Plants need a lot of different nutrients, not
simply N, in order to produce the vitamins they are normally grown for.
According to my understanding, the standard NPK analysis for properly aged
compost is about 1-1-1. Thus, this is a problem that an organic gardener
would actually have to work very hard to have. It can't be done
accidentally in the normal home gardening situation.
What this research tried to establish is that it is possible to do stupid
things with plants. What it does NOT establish is that these stupid things
are likely to occur in a home setting.
I've read some of the other material published by the New Alchemy Institute
and, quite frankly, they remind me of chicken shakers dressed in beads,
feathers and paint. They have a mystical / political point to make and I
want nothing to do with it.
Their butterhead lettuce testing looked at a measly 42 heads. That sample
size is too small to be useful for anything except scaring the unwary.
for the mustard arsenic issue....

This is a change in subject.
