Food (MGS3)
From the Metal Gear Wiki
This article is based on the food eaten in Metal Gear Solid 3: Snake Eater.
Eating food replenishes stamina. How much stamina Snake has affects how quickly he recovers from injury. The greater it is, the faster he heals. Having low stamina (less than 50%) causes Snake's hands to shake while holding weapons. Also, his tummy will start to rumble, alerting guards to his location. Both of these effects increase as his stamina gets lower.
Naturally occurring foods (i.e. everything but rations, instant noodles, Calorie Mates, and the Hive of Pain Hornets) can spoil over time. Spoiled items should be discarded, as eating spoiled food will give Snake food poisoning that must be cured with digestive medicine. However, many enemies, if they find spoiled foods that Snake has thrown, will eat them and get food poisoning themselves. This strategy can be very helpful in defeating The Fear.
