Now I am not someone who believes everything I hear, but an
interesting excerpt I heard on the Channel 5 programme about fitness

than those grown and eaten in the 20's
can anyone really confirm this which must be yet another really good
reason to grow your own food as much as possible, and why are they
less nutritious. They gave two examples cabbage and spinach.

It's possible that the high use of nitrogen fertilizer may cause that or
the modern varieties used for quick growing. Certainly it's noticeable
that some older varieties of veg have more taste ie. Majestic potatoes
for chips.
It's because they have taken all those great chemicals out of them,
insecticides etc.
