Kosher foods are permitted in the Jewish religion—Trayf foods are forbidden. Meat and dairy products cannot be combined or eaten in the same meal. The only seafood that is kosher are fish with fins and scales (no lobster, clams, calamari, octopus, or crab). Every fruit, vegetable, and grain is allowed except for grape products. No animal that died of natural causes can be eaten. Only animals with no flaws or diseases can be eaten. Gelatin cannot be eaten because it is made from horse-hooves.
