Which substance is included in the definition of food according to city health regulations?

The definition of food according to city health regulations includes substances that are intended for human consumption, which makes ingredients used in food preparation a primary component of this definition. This encompasses everything from raw ingredients to the final packaged products that are meant to nourish people. The regulations aim to ensure that any item categorized as food is safe, sanitary, and suitable for human consumption, which aligns with the broader goal of protecting public health.

The inclusion of only substances that are specifically for human consumption is crucial. While alcoholic beverages are consumed by humans, they typically fall under a different regulatory category focused on alcohol laws. Catered meals involve the service and preparation of food, but they are often considered a service rather than a definition of food itself. Pet food, while important for animal health, is not included in the definition of food for human consumption under these regulations, as it is intended for animals. Thus, the correct answer emphasizes the focus on ingredients used for human consumption as the fundamental definition of food in this context.
