Quim, I started about 10 years ago, and it's been great. To be fair, I was never what you would call a fussy eater, but there were a few major things I just didn't eat and it started to annoy me, because I couldn't remember ever even trying a lot of them. So far, I have added to my diet:
Tomatoes
Cheese
Olives
Jam
Dried fruit
Sponge cake (this one may have been a bit of a tactical error....)
Custard (that one too)
Sadly, though, I have been defeated by coffee and aniseed. I have tried to hard, but it is not to be.
Speaking of hard - today, not only is there an artisan food market outside the office, which includes a stall selling nutella doughnuts, but work has given us all a chocolate for valentine's day, and not one but two people in my team have brought in cake for their birthday! But I am staying strong!
