Food with high moisture, like bread, milk or fresh vegetables, spoils quickly because microbes grow easily in them. In contrast, foods like pickles, ghee and dried grains last for months as they lack moisture or air, preventing microbial growth. Preservation methods such as drying, oiling or refrigeration help extend the freshness of such items for longer periods.
