Blimey! I got another crown...I must be on a roll!
Mrs JC I'm glad your DH stood up to Il's AND got an apology! But its a shame they caused so much grief in the first place!
Fauve, I'm currently using Tescos the GI Guide which I picked up for 99p but its been written by Rick Gallop who wrote the original GI diet book (I think ) It has some recipes though not many but it does cover the principles quite well. There are also a whole load of recipe books with guidelines on the market. I believe there is a Good Housekeeping one and Antony Worrall Thompson has done one too. His is quite good but the food is rather cheffy so I can't get my DD to eat it, and I refuse to start cooking seperate meals...that way madness lies!
Basically its Atkins but with complex carbs allowed, so you can have more fruit and veg and you can eat some pasta and rice although the wholemeal or brown options are lower GI. Basmati is supposed to be lower GI too and sweet potatos are better than normal, then new potatos. You can lower the GI of the carbs by mixing a high carb with something low carb that slows down the time your body takes to absorb it...ie a baked potato on its own isn't all that good but mixed with some beans and its a much better option! Hmmm that all sounds a bit confusing sorry! Try and get hold of the Tesco book or one of Rick Gallop's other books (I think they're pblished by Virgin) as he gives lists of green(ok), amber(in moderation), and red(no way) foods.
Sorry for this long, rambling post but I hope it helps!
