I don't fly a lot, but have taken about 2 trips a year for the last 6-8 years. I've always brought my own food- not drinks since the new regulations. Coming back from Ireland last year I had cheese, bread, chocolate.... I think they took away some bananas (produce is a problem coming back into the US)

I've never had a problem packing food on a domestic flight and have brought sandwiches, luna bars, fruit, trail mix, etc. But it sounds like some people have had problems.
