Fresh apple

The Fresh apple is a food item found in Fallout 3 and Fallout: New Vegas.

Characteristics
It can restore some of your hit points without irradiating you. It is one of the few edible food items that doesn't give you any radiation, besides other fresh fruits or vegetables, and food found in a non-compromised vault.

Additionally, in Fallout: New Vegas it can reduce Starvation and Dehydration during hardcore mode.

Fallout 3

 * Fresh apples and all other fresh items are mostly found in Rivet City Science Lab. There are four apples here. Be aware that taking them is a crime.
 * One can be found in the ladies' room of Arlington Library, at the base of the garbage can.

Fallout: New Vegas

 * These can be found on Legion troops more than anywhere else.
 * Certain Fiend bases will also have them, for instance, the shelf near Cook-Cook.
 * The kitchen behind an easy locked door in Vault 3 has 4 apples on the shelves.

Fallout 3

 * If dropped on the ground in Rivet City, some of the scientists will pick them up.
 * If you stand around long enough, Janice Kaplinski will eat the ones in the lab.

Fallout: New Vegas

 * Since the apples in New Vegas couldn't have come from the Rivet City experiments, It is suggested that somewhere there is an apple tree that produces them.
