and probably just so the government can persuade us to shell out on overpriced fruit and veg from supermarkets 
the reason i think it is bullshit is because i decided after a christmas of stuffing myself with junk food and drinking most evenings a bit more than usual i was going to detox and since early january i have been making a converted effort to eat at least 5 portions of fruit and veg a day. as prior to this i was lucky to manage one or 2. mainly because of the cost but also because i dont like it :o
well after my weeks of diligent healthy eating, i have not noticed ANY difference, womens mags would have you believe you will have "glowing skin" if you eat lots of fruit and veg and all sorts of other wonderful benefits.
but no. i feel and look as shit as i ever have. 
or does it take longer than a month to work? :o
