Boyd’s Bible Dictionary:

In Bible sense, food of any kind
(Gen. 1:29; Lev. 2; 6:14-23; Matt. 15:37; Luke 24:41).

Concise Bible Dictionary:

Several Hebrew and Greek words of various significations are so translated, but scarcely any refer to flesh; the general meaning is food of any sort (Gen. 1:29-30; Ezek. 47:12; Acts 27:33-36).
