i'm with lofty, i'd actually find it really difficult not to eat 5 portions a day, most days it's more like 7-8 portions. and i don't drink much fruit juice so most, if not all, of my daily portions come from fruit and veg. it's really easy, you just need to get into the mind-set. i've just made a lasagne and it's got carrots, onions and mushrooms in it, loads of them, along with the mince and the tomatoes, so there's a whole pile of them to start with. a nice bowl of salad and chopped tomatoes with it, and a couple of nectarines this evening, not to mention the veg soup and salad sandwich for lunch. easy.
ps. how old do you have to be to qualify as one of the oldies??
