What is the main reason for storing food away from walls?

Storing food away from walls is primarily important to allow for air circulation. Proper air circulation helps maintain a consistent temperature around food items and prevents the buildup of humidity, which can lead to spoilage or mold growth. Additionally, this practice can enhance the overall cleanliness of the storage area by making it easier to clean and inspect for potential issues, such as pests or product deterioration.

While preventing damage, reducing odors, and minimizing pest attraction are important considerations in food storage, they are not the primary reason for the specific practice of keeping food away from walls. Proper air circulation ultimately contributes to maintaining the quality and safety of the stored food, making it the crucial factor in this context.
