Fruit is good - stay off oranges and pineapple and grapefruit for the first couple of months as they may be too acidic.
Also stay away from chocolate, sweets, cake, biscuits, icecream apart from minimilks, fizzy drinks, squashes unless they have no added sugar. All this will make you ill!
You will find that your tastebuds have probably gone haywire anyway so food will not taste as it should - it comes back, promise.
I have a friend who had a bypass in June and her main problem is with carbohydrates - anything remotely carb and she dumps for England - the hospital is trying to sort her out. Its rare so dont worry about it!
