Food, in RuneScape, is what enables the player to regain Health, although some foods may have other effects as well. Food can be obtained through the Cooking skill, as a drop from certain Monsters, from other players, or from non-player characters. The highest healing food for non-members is an anchovy pizza; for members it is the rocktail soup with 1 bite. However the fastest healing food for members with multiple bites are summer pies which only takes 0.6 seconds per bite (3x faster than some types of food).
The Legacy update has slightly changed the way food healing works. You can find out your maximum health recovery from eating food by multiplying your constitution level by 25. So if your constitution level is 50, then you can heal up to 1250 lifepoints. This means that you can also find out the required level to eat any food by taking the maximum heal of that food and dividing that by 25. If your constitution level is lower than this number, then you will be restricted to healing the maximum for your level.
There are many types of food: fish, meat, bread, cakes, pies, and pizza. Some foods, such as pies, cakes and pizzas, have two or more "bites" or "slices". This is a downside that can easily be remedied by using the food on a Cornucopia in battle (but it doesn't interrupt your attacks) then using it to heal your life points. There are also foods which grow from the ground such as potatoes, cabbages, and onions; those items can be put into baskets and sacks. You could also get food as a treasure trail reward, in the form of purple sweets or biscuits. Lastly, there are holiday items food such as pumpkin and easter egg. It is strongly recommended that a player does not eat holiday items, as all are rare and extremely valuable.
Note: Eating 1 part of a pie only takes 0.6 seconds and eating 1 shark for example takes 1.8 seconds (3x longer), so overall you can heal faster with high level pies and the limit is 330 with summer pies.
Some foods affect stats other than life points. Wine increases life points, though it temporarily lowers the drinker's Attack level while their Strength level temporarily increases. Beer raises your Strength while reducing your Attack. The negative effects eventually wear off though, and the affected stats go back to normal in time. Most effects do not stack.
Raw baron sharks are caught under the influence of the juju fishing potion. When cooked this food heals an initial 2000 life points and then 50 life points a second, for 10 seconds. Wearing a shark's tooth necklace extends it another 5 seconds, making it able to heal 2750 life points total.
This potion is consumed in 4 doses (1000 life points per sip). It has other side effects. While possibly not as efficient for dangerous combat situations it may prove useful for staying long doing activities such as agility.
This potion is consumed in 6 doses (1000 life points per sip). It has other side effects. While possibly not as efficient for dangerous combat situations it may prove useful for staying long doing activities such as agility.
This potion is consumed in 4 doses (1300 life points per sip). It has other side effects. While possibly not as efficient for dangerous combat situations it may prove useful for staying long doing activities such as agility.

Here are factors to consider when choosing the right food:
Heal per bite: players should try to find food that heals more in one bite than the max hit of dangerous monsters they train on. This should not pose a problem for players who train on much weaker monsters than they are.
Space: some items require space, like baskets of strawberries to take out strawberries. Monsters drop items that requires space, so consider a monster's drops and frequency of drops when bringing food.
Time to eat: try to avoid eating during combat if it is not deadly. Eating in combat is wasteful if you get damaged while eating. Some areas have aggressive monsters that hit hard and foods that take multiple bites, like cake, cause problems. You cannot attack while you are eating either.
Purple Sweets and biscuits are the only stackable food in the game. Purple sweets heal 200 life points and restore 20% run energy per serving, and biscuits restore heal 250 life points and 10 prayer points each.
The animations for eating food were updated with the release of the Dungeoneering skill.
In Daemonheim, it is possible to "feed" a fellow party member by using a piece of food on them, which makes them perform the eating animation and heal, using the food from your inventory. This is not possible outside of Daemonheim.
On German servers, the old eating animation is still in effect.
Most foods take 3 game ticks to eat; exceptions are purple sweets and pies.
