Does anybody know where i can find a list of excatly what can and can't be taking into the ground (food/drink wise)?

Also, can you watch a game, then leave the stadium and re-enter?

Yes.

No bottles, (if my memory serves me right you can take in a plastic bottle with no lid, just put the lid in your back pocket)..but apart from that any-thing, you can take in a cool bag

I wasn't ever checked about anything. They just let us straight through the turnstiles, then we walked up to the stadium and wandered around until we found some seating that we liked. No one check us about anything, which was a surprise considering that we had bag checks at Cardiff, and drinks taken off us + bag checks at Wembley for the 08 CC.

Pretty much what happened to us, between three of us we had two big cameras and decent sized lenses, they never even asked what was in our bags...

Word of warning though, I wouldn't rely 100% on it being the same, I'm a diabetic so I get some leeway on food and drink I'm allowed to take in, dunno about anyone else if they decide to get strict.

I'm an alcoholic, doesn't mean they'll let me take beer in though

I went in last year and had the 2 kids with me and a bag full of snacks, drinks etc. They searched it but everything was fine (well not everything )
