The term "inedible" refers to substances that are not safe or suitable for consumption. This can include items that are toxic, spoiled, or otherwise unfit to eat. Common examples of inedible items are certain types of mushrooms, spoiled food, and non-food materials like plastic or metal. Inedible items can pose health risks if ingested. For instance, consuming inedible substances can lead to food poisoning or other serious health issues. It is important to distinguish between edible and inedible items, especially when foraging for wild foods or preparing meals at home.
