In fact I recall in an early episode, Wesley Crusher fell into a holographic body of water, and when he left the holodeck and went to the bridge, he was still wet.
But replicated food is not holographic food. It is resequenced molecules from ship's waste. Commander Tucker once answered space-program fan mail on Enterprise. schoolchildren wrote to the crew about their mission and one kid wanted to know what happens to the ships waste? Tucker answered with an astonished, "a poop question?" and then responded by explaining how they resequence the molecules in their poop and garbage to replicate items like boots and hand-held tools. There were no food replicators on the first enterprise so they had an onboard chef that noone saw. It is through extrapolation we can conclude that replication of food eventually evolved through the same means.
Lab grown meat, on the other hand sounds dangerous. While the cells of animal flesh have been cloned in small amounts for medical purposes such as skin grafts, these larger sheets could en up more like mush than animal flesh due to the lack of excercise. Its still inconclusive what stretching will do for it. Real animals will still need to be harvested to provide stem cells.
