The Lostaways have several sources of food.
Natural
Protein
- Pork from feral boars, generally hunted and killed by John Locke. (However, since filming with boars is a production nightmare, boar has been deemphasized as part of the Lostaway diet.)
- Seafood, including fish and sea urchin, usually procured by Jin, who was raised by a fisherman, and mussels, which can be pulled off the rocks at the beach
- The Tailies successfully caught, killed and cooked up a feral chicken, however chickens have not seen near the main camp
- Danielle is depicted in a deleted scene on the Season 1 DVDs as eating a raw egg, likely liberated from a bird's nest
Carbohydrates
- Fruit, including plantains, bananas, mangos, guava and papayas, often gathered by Kate
- Coconut milk and the flesh of the coconut
- The contents of Sun's garden, which are unidentified, but which may include edible plants
Artificial
- The Dharma Supply Drop, which provides them with Dharma-branded staples familiar to consumers of the Western diet, including junk food like Apollo Bars, Dhallomars and Dharma Ranch Dressing. This food, originally discovered in the Hatch, was the source of The Big Feast. It may be irradiated, as the ranch dressing, at least, can last for seven years without refrigeration.
