In the food and health-oriented world, you are defined by the food you consume. Food Classes imagines a land and government that monitors its citizens' food consumption, questioning the values of privacy, equality, the price of sustainability, and an alternative "class system". Each citizen has a sensor implemented inside the oesophagus which tracks the nutrition that the person will ever eat. The sensor radiates a shape of a five-petal flower on the person’s neck, which reflects the different food types the person digests. For example, when someone eats a vegetable or a fruit, one of the petal leaves will be filled in green for 24 hours. People who eat healthy to be efficient and productive, while people who eat unhealthy food are seen as inefficient and overall a burden on the system. Therefore, the healthiest do not pay taxes, as they only improve society. The unhealthy pay a heavy price for their nutrition habits. 

Eventually, people become affected by that policy. The healthier food is in extreme demand and therefore very expensive. As people are aware of each other’s nutrition by looking on each other’s necks, people suffer from discrimination over their flower’s status.
