It is important to keep food away from humidity, air, light and high temperatures. (Think HALT to help you remember). Of these, high temperatures are the most destructive to the quality of food.
When you have a choice, avoid storing food in clear plastic containers which diminishes nutrition and quality of food with exposure to light. In humid climates, transfer food in #10 cans to ziplock or other closeable bags and return it to the cans for further protection.
