RuneScape/Food

Food is used to heal (regain hitpoints). Different foods heal different amounts of hitpoints.

The food items that can be cooked like fish and meat will often have a higher selling price raw compared to cooked when dealing with other players. This is because there is some demand by players to buy raw foods specifically to raise their cooking stats.

Fish and shellfish
Every player needs food to heal their HP. Since the higher fish heal a large amount of HP, there is a great market for them.

It is recommended that players do not sell their fish to General Stores or Fish Stores, but instead, sell them to other players.

Falador and Edgeville bank are the best places to sell fish. Or for members the Catherby bank is also good.

The low level fish (shrimp, sardine, herring, and anchovies) are rarely bought. Lobsters and sharks are the best to sell for fast money making.

Meat
Some monsters will drop meat when they die. It is a common source of food and can help heal your hit points if eaten once it has been cooked. However there is always some chance of failure in cooking that could instead result in burning the food.

Burnt meat is what you get when you fail to cook raw meat properly. It is completely useless, so drop it if you accidently burn your meat.
