Humans acquire, store, and discard food using a variety of methods.
People may grow, fish, or hunt some of their food, or they may purchase most of it from supermarkets or specialty stores.
If there is limited access to energy sources, people may store small amounts of foods and get most of what they eat on a day-to-day basis.
In homes with abundant space and energy, however, people purchase food in bulk and store it in freezers, refrigerators, and pantries.
For example, someone who is not hungry may eat a piece of cake that has been baked in his or her honor.
People eat according to learned behaviors regarding etiquette, meal and snack patterns, acceptable foods, food combinations, and portion sizes. For example, for some groups it is acceptable to lick one's fingers while eating, while for other groups this is rude behavior.
A cultural group provides guidelines regarding acceptable foods, food combinations, eating patterns, and eating behaviors.
Compliance with these guidelines creates a sense of identity and belonging for the individual.
In either case there must also be proper disposal facilities to avoid environmental and health problems.
There are innumerable flavors and food combinations.
